Measuring tool management function submodule, be substantially carried out the creation of measuring tool, the control of measuring tool state and The calculating of measurement result；

Management function submodule is drawn in display, is mainly responsible for the display process of control measuring tool, measurement result.

As it can be seen that measuring and calculating module is applied in measurement process, mainly measurement process is controlled, is specifically being surveyed Control measuring tool obtains measurement result during amount.It should be noted that realization process about survey calculation is herein not It repeats, sees detailed description below.

It should be noted that custom formula setup module can specifically use the setting method of following any measure equation To realize the customized of measure equation；Measuring and calculating module specifically can realize meter using following any measurement method It calculates.

Firstly, being illustrated to the specific implementation process of custom formula setting.Specifically, this application provides a kind of surveys The setting method of formula is measured, this method can be applied in measuring device, it should be noted that measuring device can be a survey Amount system.See Fig. 3, it illustrates the detailed processes of the setting method of measure equation, include the following steps S301~S303.

S301: the measure equation of user's input is obtained；Wherein measure equation is made of measurement element, and measurement element includes surveying Measure result items, measurement index item and the calculation to measurement index item.

Wherein, the structure of measure equation mainly includes three parts, respectively measurement result item, measurement index item and to measurement The calculation of index item.The three parts may be collectively referred to as measurement element.Wherein, it is calculated obtained by measurement result item, that is, measure equation As a result title；Measurement index item, that is, measurement result obtains relied on parameter factor；Calculation generally includes operator Number and/or operation function etc., indicate the calculating process to measurement index item.

By taking C=A+B as an example, what C was indicated is measurement result item, and A and B are respectively measurement index item, and+expression is to measurement The calculation of index item A and B.Certainly, this is only one and simply illustrates, and measurement index item and calculation may be used also To be more complicated form.

If can not just be obtained according to calculation it is understood that measurement index item cannot be calculated in measuring device Measurement result item.Therefore, measurement index item is that measuring device can directly measure to obtain or can be based on other measurement indexes The measurement index item that item is calculated.

User can input customized measure equation to measuring device, and input mode can be various forms, including but It is not limited to input by character, sound, image etc..

A kind of specific input mode is to provide set interface, includes measurement result item, measurement index item in set interface And the input control of calculation；Obtain measurement result item, the measurement index item and to survey that user is inputted by input control The calculation of figureofmerit item.

Specifically, in order to facilitate user's input, measuring device provides set interface, includes input control in set interface Part.Input control can be there are many form, for example, input control includes Text Entry, so that user can be by external defeated Enter equipment input measurement element.

Alternatively, input control may include selection control, as input control includes: measurement index item option control and Calculation option control, is provided with multiple alternative measurement index items in measurement index item option control, and user can be with It selects therein any one or more, the operation of measurement index item is selected to be equivalent to the operation of input measurement index item.Similarly, The input operation of calculation is also possible to the operation that user selects calculation in calculation option control.

Still it is illustrated by taking ultrasonic diagnostic equipment as an example.

Assuming that user wants to know about the case where this measurement result item of ratio of head circumference (HC) and humerus long (FL), but ultrasound There is no configurations to obtain the corresponding measurement method of measurement result item in equipment.Therefore, the measurement knot can be obtained in order to realize Fruit, user can be a kind of its customized measure equation, and in order to facilitate the customized measure equation of user, ultrasonic device can be aobvious Show screen display set interface, includes equation editing frame and Formula Input Technology panel in set interface.

It include the option for each measurement index item that ultrasonic device can measure in Formula Input Technology panel, In, it include the head circumference HC and long FL of humerus.It should be noted that the measurement index item for including in panel is that measuring device can be straight It connects measurement to obtain or can be based on the measurement index item that other measurement index items are calculated, panel is by these measurement index items It is supplied to user, allows the user to remove to calculate new measurement index item, new measurement index item using these measurement index items I.e. above-mentioned measurement result item.In addition, further include having various calculations in Formula Input Technology panel, as basic operation formula+,-, × ,/etc. and basic mathematical function sin, cos etc..

For example, user input measurement result items Ratio_HC_FL in equation editing frame at this time, and in Formula Input Technology panel The middle selection head circumference HC and long FL of humerus and oeprator/and *.The measure equation finally entered can be with are as follows: Ratio_HC_FL= [HC.HC'mm']/[FL.FL'mm']*100；Wherein, that HC.HC is indicated is measurement index item head circumference (i.e. perimeter) HC, FL.FL That indicate is the long FL of measurement index item humerus.Head circumference HC being set to one in ultrasonic device, there is measurement on a large scale to refer to Item is marked, may include multiple specific measurement index items under the measurement index item, for example, in addition to head circumference can also include head circumference Major diameter OFD, the pregnant age GA etc. gone out by circumference calculating, what the HC.HC of user's input was indicated be head circumference lower on a large scale this have The measurement index item of body.The meaning of FL.FL known to similarly.

The measurement index item provided in Formula Input Technology panel can wrap containing unit, in formula as measured above, single quotation marks Interior mm indicates millimeter, is the unit of the measurement index item in same square brackets.After user selects measurement index item, unit can be with Automatic addition.Alternatively, unit can be what user oneself was manually entered by external input device.

, can also be by it should be noted that when if user wants to modify the measurement element in some existing measure equation It is realized according to aforesaid way.Custom formula edit mode is realized by visual edit graphical interfaces, is realized humanized The mode of operation of simple, intuitive.

S302: the target configuration sentence that target configuration file to be generated includes is determined；Wherein target configuration sentence is used for Indicate that target configuration file is performed how to handle the measurement element that measure equation includes.

Wherein, it after obtaining the customized measure equation of user, needs to generate configuration file according to measure equation, need in other words Measure equation is saved in configuration file.Match it is understood that computer equipment needs to rely in actual operation File is set, includes the relevant information of operation in configuration file, in the application scenarios of the application, the configuration file of measuring device Middle record has how measuring device specifically executes measure equation, is just able to achieve the survey calculation purpose of measure equation.

It should be noted that configuration file is made of configuration sentence.The configuration that the configuration file of different function type includes Statement type is different.Therefore, it is first determined measuring device needs to generate which or which configuration file, for the ease of retouching It states, configuration file to be generated is known as target configuration file, then, it is determined that the configuration file needs of this kind of function type include Which has configure sentence, and for ease of description, the configuration sentence that target configuration file includes is known as target configuration sentence.

When what target configuration sentence indicated is that target configuration file is measured equipment execution, how measuring device is specifically handled The measurement element that measure equation includes.Process content may include but be not limited to: how measuring device be enable to be calculated Measurement index item obtains measurement result item how is calculated after measurement index item, obtained measurement index item and measurement knot How fruit item shows etc..

In order to make it easy to understand, this application provides the target configuration files of following three kinds of different function types.Specifically, exist In practical application, measuring device can configure following three target configuration file: listing formulas configuration text according to measure equation Part, formula details configuration file, index item detailed configuration file.

Listing formulas configuration file, for indicating how measuring device shows the measure equation being made of measurement element.

Concrete application scene is that in actual measurement, measuring device can show measure equation list, for selection by the user It uses.What measure equation list included is all measure equations that measuring device can be realized, therefore the customized measurement of user Formula also may be embodied in the measure equation list.The displaying process of measure equation list need to rely on listing formulas configuration File, therefore the customized measure equation of user needs to add in configuration file.Specific adding procedure is needed in formula The configuration sentence on how to show the customized measure equation is added in list configuration file.

Formula details configuration file, for indicating how measuring device calculates the measurement result item of measure equation.It needs It is noted that the measurement index item title that measuring device built-in system defines may be with the customized measurement index key name of user Claim corresponding conversion relationships that are different, therefore may include the two in the configuration file.In addition, configuration file can also include how Show measurement result item.

Concrete application scene is, after user selects some measure equation in measure equation list, measuring device executes should The corresponding formula details configuration file of measure equation, to obtain measurement result item.Also, according to the display side of configuration file Formula shows measurement result item.

Index item detailed configuration file, the measurement index item for being included for indicating how to obtain measure equation.Namely It says, which is to prepare each basic data, the measurement that basic data, that is, measure equation includes for the calculating of measure equation Index item.Since measurement index item can be the measurement result item that other measurement index items are calculated, measurement index item It is also assumed that being a kind of measurement result item, therefore the function of the configuration file and above-mentioned formula details configuration file is passed Formula be it is roughly the same, it is also seen that this point from citing below.

It should be noted that the above-mentioned function of target configuration file is realized, it is based on the mesh for including in target configuration file The function that standard configuration sets sentence is realized, therefore the function of configuration file is it is also assumed that be the function of configuring sentence.

Which measurement function measuring device needs to realize, then the corresponding configuration file of these functions can be generated.Determine to After the configuration file of generation, it can also determine that the configuration file needs the configuration sentence for including, and can determine Measure the rule of element composition configuration sentence.

S303: it according to the measurement element of measure equation, generates target and configures sentence, target configuration sentence is for forming target Configuration file.

Wherein, the measurement according to the rule of measurement element composition configuration sentence, according to the step S301 measure equation obtained Element generates target and configures sentence.Target configuration sentence can form target configuration file.

Configuration file can be various forms, such as (EXtensible Markup Language, can by text formatting, XML Extending mark language).In the configuration file of XML format, configuration file includes node label, and the sentence that node label includes is i.e. Configure sentence.

Three target configuration files of XML format are illustrated below.

Assuming that three target configuration files be based on above-mentioned measure equation Ratio_HC_FL=[HC.HC'mm']/ [FL.FL'mm'] * 100 and obtain.Measurement result item in the measure equation is Ratio_HC_FL, and measurement index item includes HC.HC, FL.FL, calculation include being divided by and multiplied by 100.

The title of listing formulas configuration file are as follows: EquataionList.xml, the structure for configuring sentence are as follows:

The value of parameter can be shifted by the formula in oval basic data and Formula label node in a kind of situation It obtains, such as the KW_Arg3 that OFD (HC) is relied on is exactly directly to be calculated by formula KW_Arg3=2*KW_Arg2.

Parameter value needs to rely on some end value of other measurement items, such as measurement index item GA result in another case Item relies on measurement item KW_GA, and end value is calculated by the calculation formula in Formula label node, and the calculating is public Formula are as follows:

KW_GA=CallExternDataEx (KW_AC, KW_Arg1)/KW_Arg1.The wherein function in the calculation formula CallExternDataEx (KW_AC, KW_Arg1) indicates the KW_Arg1 end value that AC measurement item is obtained from measuring device system, This requires measuring device systems to save the basic data of some measuring tool.Preservation process needs pass through What SetExternDataEx (KW_HC, KW_Arg1) was realized, it indicates to join the KW_ELLIPSE_LCIR perimeter of HC measurement item Number KW_Arg1 is saved in memory, facilitates other measurement index item should by CallExternDataEx function call when calculating Parameter value.

In practical applications, there may be wrong or other do not meet measuring device requirement for the measure equation of user's input The problem of, therefore the measurement element in step S303 according to measure equation, it can also include pair before generating target configuration sentence Measure equation carries out the step of legitimacy verifies.

Specifically, as shown in figure 4, to measure equation carry out legitimacy verifies the step of may include steps of S401~ S402。

S401: according to syntax tree building rule, the corresponding syntax tree of building measure equation.

Wherein, the corresponding syntax tree of measure equation is each measurement element that measure equation is indicated in the form of tree node. Since tree has traversal rule, the measure equation can be restored according to traversal of tree rule.Construct the purpose of syntax tree It is, in order to use syntax tree to verify the legitimacy of measure equation.

Specifically, building process may comprise steps of A1-A4.

A1: morphological analysis is carried out to measure equation, to extract the lexical element that measure equation includes；Wherein lexical element is used In the lexical structure for indicating measure equation.

Wherein, firstly, analyzing using morphology resolver measure equation, lexical element is obtained.

For example, writing flex morphology resolution file according to the syntax rule of open source morphology resolver flex, then passing through Morphology resolution file is generated morphology resolver code by flex tool, is provided with interface function, interface function in the code file The measure equation that user inputs can be divided into independent lexical token token one by one.

Lexical token token is broadly divided into six major class, specifically includes floating number, oeprator, basic mathematical function, name Title, measurement item unit and space newline.

It is that forms, the lexical token token such as bottom index are denoted as by [0-9]+" " [0- that floating number, which includes integer, decimal, e, 9] * ([Ee] [-+]? [0-9]+)? | " "? [0-9]+([Ee] [-+]? [0-9]+) number of regular expression matching out.Operator Number include+,-, * ,/, ^ ,=,；, () etc. symbols, token be denoted as symbol itself.Basic mathematical function class include " SIN ", " COS ", " TAN ", " SUM ", " MIN ", the common mathematicals function such as " MAX ", lexical token token are denoted as function itself.Name Claim the variable name mainly relied on including measure equation, function name etc., lexical token token is denoted as by [a-zA-Z] [a-zA-Z0- 9_] * regular expression matching character string.Measurement item unit mainly includes " cm ", " m ", " mm ", " cm/s ", " m/s ", " mm/ s","cm²" all common units are waited, lexical token token is denoted as unit itself.Although space, line feed and branch end mark It can be identified as special lexical token token, but the practical token is skipped and do not handled, is equivalent to no token.

By taking this measure equation of above-mentioned Ratio_HC_FL=[HC.HC'mm']/[FL.FL'mm'] * 100 as an example, Flex word The measure equation is finally divided into 13 lexical token token by method resolver, be respectively as follows: Ratio_HC_FL ,=, [, HC.HC、mm、]、/、[、FL.FL、mm、]、*、100。

A2: the syntactic type of lexical element is determined.

Specifically, syntax analyzer can be used to analyze lexical element, determines syntactic type.

For example, writing Bison syntax parsing file, and utilize according to the syntax rule of open source grammar parser Bison Syntax parsing file generated syntax parsing code, the code file are provided with interface function by Bison tool, and interface function can be known The lexical token token that other Flex resolver generates, and the customized grammer of user is matched, thereby executing corresponding operation.

For customized measure equation, Bison grammar parser is mainly matched: operation expression, full stop expression formula, A few class syntactic types such as function call, parameter list, assignment statement.

Wherein between operation expression+,-, * ,/, ^, as a result still be expression formula, be grammatically recursive；Variable, number Value belongs to termination expression, is end symbol, grammer not recurrence；Function call is shaped like function name, (, parameter list) form C language style function call；Parameter list sentence is divided with comma, is used for function call sentence；Shaped like title ,=, expression Formula is assignment statement.

Syntactic type corresponding to lexical element can be determined according to the method described above, by taking above-mentioned 13 lexical tokens as an example, The corresponding syntactic type of 13 lexical tokens is as follows:

Ratio_HC_FL be formula name ,=be assignment statement, [HC.HC mm] be as a whole parameter ,/be operation Symbol, [FL.FL mm] are that parameter, * are operator, 100 are parameter as a whole.

A3: according to the corresponding relationship in syntax tree building rule about syntactic type and node type, syntactic element is determined Corresponding node type.

Wherein, it is previously provided with the corresponding relationship of syntactic element and syntactic type.Such as the following table 1, it illustrates corresponding relationships An example.

Table 1

Syntactic type	Node type
		Integer, floating number in parameter list	Constant node: " K "
Measurement index item in parameter list	Title reference node: " N "
		+ ,-, * ,/, ^ operator	Corresponding operator node: "+- */^ "
" expression formula, expression formula " format list	Parameter list node: " L "
		'=' assignment statement	Evaluation node: "="
" SIN (expression formula) " built-in function calls	Function call node: " F "
		" DEF (expression formula) " custom function is called	Function call node: " C "
Bracket, branch, line feed, space etc.	Nothing

According to above-mentioned corresponding relationship, syntactic type can be converted to node type, what node type indicated is to be built Syntax tree interior joint type.Node type is different, then position of the node in syntax tree is also not quite similar.

A4: according to the node type of lexical element, the syntax tree of lexical element building measure equation is used.

Wherein, according to the corresponding node type of lexical element, the measurement element in measure equation is configured to syntax tree Node.By taking this measure equation of above-mentioned Ratio_HC_FL=[HC.HC'mm']/[FL.FL'mm'] * 100 as an example, construct Syntax tree is as shown in Figure 5.

It should be noted that the building of syntax tree has at least two effects, first is that legitimacy verifies are carried out, second is that specifically Execute measure equation.The detailed description of second effect may refer to the explanation about measurement process, not repeat herein.

S402: legitimacy verifies are carried out to measure equation based on syntax tree.

Wherein, since node type each in syntax tree is all derived from same base class, it can be easy to each node structure The syntax tree built out carries out the operation such as traversal and recurrence, and realizes that the legitimacy of expression formula detects by these operations.

Specifically, legitimacy verifies include any one of following three or multinomial: grammatical soundness verification, logically true Property verification, arithmetic unit legitimacy verifies.Syntax tree recursive traversal parsing from top to bottom since root node to building, is completed Above three verification.

It is verified about grammatical soundness.

Wherein, the grammar parser that the detection of grammatical representation formula legitimacy can be generated by open source Bison tool is realized.If The grammer of customized measure equation is unsatisfactory for its rule and requires, will error and throw exception prompt letter when constructing syntax tree Breath.

It is verified about logical correctness.

Wherein, measure equation is associated with specific business, it is possible that syntactically correct but formula logic is unsatisfactory for business In the case where demand, such as measure equation name re-defines, measure equation includes measurement index item measuring device system not Definition, the custom function parameter in measure equation are illegal etc..Therefore, logical correctness is introduced when parsing syntax tree Testing mechanism.

The mode of the validation verification for the measurement index item for including to measure equation name and measure equation are as follows: read measurement and set Standby already existing measure equation and already existing measurement index item, by measure equation to be verified and already existing survey Amount formula is compared, and the measurement index item that measure equation includes is compared with already existing measurement index item.Specifically Implementation is as follows.

Traversal parsing listing formulas configuration file and all measurement index item information configuration files, measure equation name is delayed There are in measurement item title array, all measurement index items are stored in result items title array.After traversing syntax tree, respectively The measurement index item that the measure equation name and measure equation include is looked into measurement item name array and result items title array It operates again.

If finding in measurement item title array duplicate with measure equation name, which is determined as not conforming to Method；If not finding the measurement index item that measure equation includes in result items title array, illustrate the survey in measure equation Figureofmerit item is undefined, and measure equation is equally determined as illegal.

For the legitimate verification mode of custom function parameter are as follows: by the tree node function node position of syntax tree Increase a Parameter nodes, then passes through whether the sum of parameter of left and right subtree for verifying the Parameter nodes joins with increased node Numerical value is equal, verifies to realize to function call number of parameters correctness.

About arithmetic unit legitimacy verifies.

Due to that would generally include multiple and different measurement index items in measure equation, each measurement index item may be different Unit, these measurement index items carry out basic operation operation after, it is likely that there is meaningless unit, it is therefore desirable to unit Legitimacy is verified.Specifically include following content.

Increase basic unit array in grammer tree node, basic unit array includes 5 elements, respectively corresponds 5 kinds of bases Our unit (ratio and constant are without unit).Element value is the unit order in basic unit array.Basic unit type and basic Element value comparison table in unit array is as shown in table 2.

Table 2

Derivative unit is derived by basic unit, and according to the derivation relationship between derivative flat type and basic unit Define derivative unit array.Derivative flat type and the derivative unit array table of comparisons are as shown in table 3.

Table 3

Derivative flat type	Derivation relationship	Array element value
			Frequency	1/s	{0,0,-1,0,0}
Speed	m/s	{1,0,-1,0,0}
			Acceleration	m/s²	{1,0,-2,0,0}
Angular speed	rad/s	{0,0,-1,1,0}
			Angular acceleration	rad/s²	{0,0,-2,1,0}
Area	m²	{2,0,0,0,0}
			Volume	m³	{3,0,0,0,0}
Flow	m³/s	{3,0,-1,0,0}
			Pressure	kg/m²	{-2,1,0,0,0}
Pressure/time	kg/m²/s	{-2,1,-1,0,0}

Operation rule and operation constraint are set, and are arranged between operation rule, operation constraint and the variation of unit array Corresponding relationship, the corresponding relationship is as shown in table 4.

Table 4

Using above three table, the unit of measurement index item in measure equation is verified, whether verify legal.

It is illustrated by taking Ratio_HC_FL=[HC.HC'mm']/[FL.FL'mm'] * 100 as an example.

It is made up of [HC.HC'mm'], [FL.FL'mm'], 100 3 references operation on the right side of the formula assignment statement, Wherein the unit of [HC.HC'mm'] and [FL.FL'mm'] two name nodes is fundamental length unit ' mm ', its corresponding unit Array is { 1,0,0,0,0 }, when according to measurement item operation listed in table being x/y, without constraint condition, Unit array Variation is that x and y array corresponding element subtracts each other, then Unit array will become after [HC.HC'mm']/[FL.FL'mm'] operation For { 0,0,0,0,0 }, behind multiplied by 100, x* constant in corresponding table, this operation does not also constrain unit array, It can continue to operation, it is still { 0,0,0,0,0 } that final array is constant, indicates that result does not have unit.

It is illustrated by taking Ration_BPD_AC=([BPD.BPD'mm']+[AC.GP'g']) * 2 as an example again.

On the right side of the formula assignment statement, the unit of [BPD.BPD'mm'] and [AC.GP'g'] two name nodes is respectively Fundamental length unit " mm " and basis weight unit g, its corresponding units group are respectively { 1,0,0,0,0 } and { 0,1,0,0,0 }, Due to two kinds carry out be "+" method operation, by rule constraint relation table it is found that the constraint condition of x+y be x and y Unit number Group corresponding position element needs equal, and the front two of practical two kinds of unit arrays is not identical, accordingly, it can be determined that its there are units Validation error will lead to legitimacy verifies failure.

Complete above-mentioned verification and verification it is legal after, can generate measuring device system according to measure equation can identify Sentence is configured, configuration file is generated.Wherein measure equation generates the contrast relationship of the configuration file of measuring device system identification such as Shown in table 5.
