Five, embodiment

This device embodiments is described respectively below.Because the effect of this device and the realization of function are on the hardware foundation of this device, finish by the common support of a series of programs in some the concrete methods and the computing machine of packing into, therefore when the explanation embodiment, in certain scope, method and the program that some are concrete will be described specially:

(1), adopts computer printer port and IEEE 1284 standards.This device is for realizing that input and output patch simultaneously, employing has the parallel port conduct that the input and output function can man-machine interaction work and the interface channel of computing machine, with the definition of the IEEE1284 standard of in March, 1994 IEEE (international electric slip-stick artist tissue) issue to port, get 5 condition lines of state group as the basic passage that connects input, take 8 data lines as the basic passage that connects controlled output, take and latch control usefulness when encode as output channel with 1 nAUTOFEED control line.In order to connect more input equipment, the port that is provided with 31 input interface channels in this device docks with 5 condition lines of Methods for Coding and parallel port.Output device also can be encoded on the basis of 8 fundamental lines and be produced 255 tunnel output channel connectivity ports, according to purposes with take passage what encode, latch adaptive with level voluntarily outside machine, makes output connector 13 by the user.

(2), main frame connectivity port.The main frame connectivity port is one 15 pin ' D ' shape plug-in unit, has connected 32,10,11,12 and 13 pin of the condition line group of main frame parallel port, as the inlet of input channel coded signal; 2,3,4,5,6,7,8 and 9 pin that connected the data line group of main frame parallel port are as the basic controlling port of output channel; Introduce when 14 pin nAUTOFEED control lines are encoded as output channel and latch control usefulness, and introduced 21 pin low levels of main frame parallel port, as loading level the precoding of scrambler.

(3), input channel connectivity port working method.The input channel connectivity port 5 of on-off circuit 6 ₁Provide 31 tunnel input channels parallel access, offered 4 peripheral hardware connectivity ports on the machine box, patched use simultaneously, adopted 1～31 tunnel mode of working one by one for the input of different purposes, the mode of also can 1～8 tunnel concurrent working and 15～0 tunnel working is one by one implemented the access parameter of unified standard.This access parameter standard is: the switch level pulse signal of 1HZ～20KZH is low level (0V) when not working, during work be high level (+5V).Input channel inserts and must at first will transmit and carry out outer demodulation of machine or level adapted according to this standard, makes the input connector, from 3 ₂Wired access 5 ₁ Electric equipment 1 preferably adopts the method for remote-control transmitting to send out control or information acquisition, and signal is from 2 ₁The method of remote-control transmitting will transmit and give 3 ₁

About working method and concurrent working mode one by one, in general the input channel mode of working one by one is suitable for input is adopted when sending out the control device, as remote-control handle etc., input channel concurrent working mode is suitable for information monitors the occasion of collection in real time and uses, and its uses is that the fundamental line passage of condition line group obtains information.

Input channel generally is used to drive or collection, the processing of the information of a sensor device of equipment itself, exist the various concrete conditions and the requirement of the method for the frequency that transmits and collection, as 1. because of electric equipment input end work transmission frequency difference cause sampling error avoid way; 2. improve the speed that identical code repeats; When 3. input end was as remote control transmitter, 31 passages had lacked, and required number that increases the control button or the like.This device is for adapting to these needs, and the mode of the working signal that input is launched and disposal route have proposed a kind of high level and kept phase sampling processing method, the contents are as follows:

(1), the timer of signals collecting can be regulated.Be that the frequency that sampling period or software obtain code can be regulated.The trigger pip of input equipment is autotelic by hitting by the operator, or the result who produces at random by external sensing equipment, it is different that the high level of the switch level that its trigger pip of various device produces is kept the phase (promptly ' opening ' action holds time), the operator manually is generally about 300 milliseconds by the normal high level phase of keeping of switch level that percussion is given birth to, if adopt the high level of the switching pulse that sensor contact takes place keep the phase that will to keep the phase than the switch level that manually-operated takes place much smaller, in order on input channel, accurately to obtain trigger pip according to different situations, timer for sampling adopts optional way, and this device has adopted the timing way (seeing attached list 1) of optional timer sampling in the 0.1-100 millisecond.

(2), high level is kept the first sample code method of formation in the phase.If the content that some code drives only need be moved back 1 code drive actions takes place, only need to carry out once, for example mouse left click, right click only press down and take place once, should adopt high level to keep the method that the first sample code generates in the phase.And for example input equipment is the operation of handle button one class, does once to trigger, and produces one time drive actions, is the method (seeing attached list 1) that the first sample code generates.

(3), high level is kept multidigit sample code method of formation in the phase.Because some action needs to repeat a certain driving content after button is pressed, for example send out character ' H ' a plurality of and to screen, go, mouse shift action etc., if adopt the method for (2) the first sampling, it is just slow that triggering once produces an action, therefore must adopt high level to keep the method for full position code generation sampling in the phase, after button pressed down, each ' 1 ' was exactly a repetitive operation.This method is obtained the different concrete also differences of implementing according to the position:

A, the multidigit sample code generates rises behind the step every position method (seeing attached list 1).

B, damping position method (seeing attached list 1) behind the step that the multidigit sample code generates.

(4), high level is kept marshalling code generation method in the phase.This is a new method of this device invention.Because this device provides realization ' to go programming by keyboard, operate with telepilot ' operating environment, make the computer remote control manipulater of producer's exploitation convenient as the remote manipulator of televisor, some big application program straighforward operation is not enough with 31 channel code definition, the volume of the remote-control handle of doing can not strengthen, button uses inconvenience too much on the contrary, not easy to operate, therefore the present invention proposes high level and keep the method that full position marshalling code generates in the phase, adopt this method that each button need not be cooperated by other button, as ' ↑ SHIFT ' on the computer keyboard or ' CAPS LOCK ' is strong, just can work as 2 or 3 uses, it is 62 or 93 codes that 31 channel codes can be derived.High level is kept definite method of full position marshalling in the phase, at first will maximum full figure places ' 1 ' may take place to sample devices triggering work organizes into groups, by ' 1 ' order that occurs, determine every group contain ' 1 ' what, and give every group code, general first group is former channel code, second group is branch code, and Code Number is that former channel code adds ' 100 ', and the 3rd group also is branch code, Code Number is that former channel code adds ' 200 ', and so on.Then in practicality by the position occurrence number of each action, in that group, ' sitting in the right seat ' promptly obtains the code of that group.

When the operator keeps the operation of the method for timer counting in the phase at enforcement remote-control handle equipment high level, as adopt 100 milliseconds timing cycle to sample, obtain first group of code (code of former passage) and must adopt and touch method, promptly flicking key keeps the 0.1-0.4 triggered time of second; Obtain second group of code and should adopt and heavily touch method, promptly heavy button keeps the 0.5-0.8 triggered time (seeing attached list 1) of second.

(5), high level is kept full position counting method in the phase.Signal number by the timer repeated acquisition in high level is kept the phase is counted, and the timing signal multilist shows that the time that trigger action ' opens ' is long in a certain passage generation high period, otherwise timing signal represents that less the time that trigger action ' is opened ' lacks.It is relevant that full position counting method and input channel, sampling period (being timing signal) and high level are kept phase length, therefore this counting channel code has the potential of spreading code, the quantity of information of expansion input code on same passage is implemented in and produces a plurality of pulse information codes that switch level is kept on the passage.The pulse information code of these expansions is to keep length (high level is kept the length of phase) by input trigger means time of ' opening ' on a certain passage, take place ' 1 ' what and produce.In addition, this method is for gathering screen-icon flash signal counting, and development computer remote control screen target clicker also is very useful.

(6), high level is kept the first sampled signal stored count method in the phase.For with the quantity of information being a class input equipment of gathering purpose, in order constantly to obtain the purpose of sensor real-time information, can be before the equipment of each passage be started working, determine relative initial amount, adopt high level to keep the first counting method in the phase then, its code occurrence number is carried out stored count, how much characterize the real-time information amount that this code is taken place with counting; Further, carry out correlation analysis and can also handle (seeing attached list 1) as two-dimentional real-time information with time two information records of stored count and generation.

High level is kept the content that phase sampling processing method comprises six aspects, the timer that is signals collecting can be regulated, high level is kept the first sample code method of formation in the phase, high level is kept multidigit sample code method of formation in the phase, what comprise that multidigit sampling duplicated code generates plays behind the step damping position method behind the step that rises that generates every position method and multidigit sample code, high level is kept marshalling code generation method in the phase, high level is kept full position counting method in the phase, high level is kept interior the first sampled signal stored count method of phase etc., wherein 1 is to be provided with a kind of time, and all the other 5 is the concrete practice.The parallel channel that this device adopts and the access way of on-off circuit, for the enforcement of this scheme provides reliable and stable branch art support, guaranteed that each passage requires to choose different input signal acquisition methods according to reality, make high level keep the running flexibly cleverly of phase sampling processing method, in same working environment, show what one's be, guarantee that the fastest the execution the most accurately drives or the most accurate image data, can control the high level of input triggering simultaneously and keep the quantity of information of phase with the expansion input code.Above-mentioned 1～6 enforcement can be accomplished on each passage, all represents with the form of different API codes, is provided with in the action center program, also can select in user program.

When making the computer program remote-control handle, if it is not enough to feel to import the button of 31 passages, can select (4) high level to keep full position marshalling code generation method in the phase, be used for increasing the input channel function, deriving 31 the tunnel under the feelings that do not increase hardware is 62 the road or 93 the tunnel, has avoided common keyboard employing ' SHIFT ' or ' Capslock ' key to come the extended keyboard function; The continuous action of button if desired as moving up and down about mouse action etc., should be adopted multidigit sampling duplicated code method of formation; If input channel is used for the information acquisition of sensor, can select 5 high level to keep in the phase full position counting method or 6 high level are kept the first sampled signal stored count method in the phase, trigger pip to sensor is counted processing, can on same passage, expand the quantity of information of input code, be implemented in and produce the pulse information code that switch level is kept on the passage.These have guaranteed the range of control of input and the precision that quantity of information is gathered, and offer out the person and remove to develop the computer interface product that innovation more meets society need.

Should illustrate, this device is the operation circuit connection that offers electric equipment in the mode of passage, each operation circuit need take passage of this device, if for example an electric equipment has 3 tunnel inputs to send out the control circuit, what this device provided so 31 the tunnel can insert 10 these electric equipments, and in addition surplus 1 passage is not used.Be terrible more input control or sampling channel, can adopt high level to keep full position counting method in the phase on the one hand, obtain the quantity of information of expansion input code on the same passage, be implemented in and produce a plurality of pulse information codes that switch level is kept on the passage.

(4), output channel connectivity port working method.Holding circuit 8 provides 8 basic passages of output, by output channel connectivity port 11 ₁, give electric equipment 14, as the input type passage, stipulated the access parameter of unified standard, this access parameter standard is :+5V level inserts, the working method of 8 tunnel drivings of accepting one by one.Therefore, operating voltage and access normal voltage coupling for output channel, also in order to increase the port number of output, the user in use, what of amount expand the back with 8 basic output channels and use as required, should at first make 1～255 passage of encoding process generation to 8 basic passages device outside, carry out the latching of adaptive and controlled passage of voltage simultaneously, make the device of output connector 13, again by 13 ₁With 11 ₁Mutually in succession.1～255 output-controlled passage, all represent in the mode of code, its form is an api function, each controlled ports provides 2 codes, be controlled beginning code and controlled end code, the developer encodes outside device on the circuit that latchs with the nAUTOFEED control line as latching output level ' 1 ' or ' 0 '.The code of whole controlled passage complete shut-downs also is provided.

Mode scheme as the networking of an electric equipment unit, input channel is for implementing control one by one to exporting 255 numerous controlled passage, make operation directly perceived, the program of being developed of this device provides controlled output channel ' 255 road monitor boards ', 255 icons appear on indicator screen, choose click one by one by mouse, to controlled output channel unlatching, duration, close with the setting and the control project of controlled code and select.It is the center of an output channel master control, Surveillance center.Certainly, the special requirement of some application program, some controlled outputs commonly used or specific use are logical

Road or project simultaneously should be by wireless telecommunications system or the controls of input remote controller, and everything is finished by the code definition of the user interactions mode of action center.

(5), on-off circuit.On-off circuit 6 has 32 switching tubes, and 1 switching tube is used for teleswitch control, and 31 switching tubes are used for coding.Switching tube is C9013, by 32 tunnel working methods designs of adopting the crowd to know, sees a Figure of description 2:1 channel switch, decoding circuit figure.The duty of 32 passages of 32 switch controlled adopts the working method of operation one by one.During input equipment work, the level of the switching pulse of sending here on its a certain parallel channel is from 3 ₂Through input channel connectivity port 5 ₁Be added in the B utmost point 6 of switching tube C9013 ₂, a certain passage of input equipment is not when working, and switch level is an off state always, 5 ₁Be low level 0V, corresponding C 9013 is ended always, the C utmost point 6 ₁Keep high level 5V; When if a certain passage of input equipment is worked, the 5V high level is by input connector 3 ₂Through input channel connectivity port 5 ₁Be added in the B utmost point 6 of switching tube C9013 ₂, C9013 is triggered the C utmost point 6 ₁Conducting immediately, saturated, overturning is low level 0V.6 ₁Be connected 7 of next stage scrambler 74HC245 ₁Pin, 7 ₁Pin is that 19 pin of 74HC245R enable control and the control of 1 pin direction, makes 74HC245 obtain the 0V level of the work that triggers.
