In order to reduce the waste of energy sources by the conventional auxiliary and public units (also called auxiliary and public equipment), the application provides a control method of the auxiliary and public equipment, so as to reduce the waste of energy sources by the auxiliary and public units. The public and auxiliary equipment control method is applied to the server. The public and auxiliary equipment controlled by the scheme is provided with interfaces for remote state acquisition and remote control. So that the server can detect the state of each public and auxiliary equipment and control the start and stop of the public and auxiliary equipment.

The public auxiliary equipment can be additionally provided with PLC hardware, a WIFI module interface, a Modbus communication interface and the like, so that the public auxiliary equipment has data communication capability. Or other equipment (such as a computer or a control device) can remotely acquire the state data of the public and auxiliary equipment through an additionally arranged interface and can control the equipment.

Referring to fig. 1, fig. 1 is a flowchart of a control method of a public and auxiliary device according to an embodiment of the present application, and the steps included in the method will be described with reference to fig. 1.

And S100, determining whether the workshop needs to use the public and auxiliary equipment in a preset time period from the current moment.

The specific length of the preset time period can be set according to actual requirements, and the specific length is not limited here.

The auxiliary equipment refers to equipment or environmental equipment for achieving process conditions, and can be, for example, constant temperature dehumidification equipment, vacuum equipment, cold water equipment, circulating water equipment, compressed air equipment, nitrogen production equipment and the like. The public auxiliary equipment control method can be used for controlling any type of public auxiliary equipment.

Wherein, constant temperature dehumidification equipment, cold water equipment, circulating water equipment, compressed air equipment and the like are public auxiliary equipment for achieving process conditions. The nitrogen making equipment and the vacuum equipment are environmental equipment.

In the case where a plurality of types of public and auxiliary devices exist at the same time, the public and auxiliary devices can be controlled by the public and auxiliary device control method for each type of public and auxiliary device.

There are several implementations of determining whether a plant needs to use a public auxiliary device.

In the first embodiment, the specific mode of determining whether the workshop needs to use the public and auxiliary equipment in the preset time period from the current moment can be that all production tasks in the workshop are acquired in the preset time period from the current moment. Then, a standard operation flow associated with each production task is obtained, wherein the standard operation flow comprises process steps and process conditions of each process step. It is then determined whether the plant requires a common auxiliary equipment for assisting in achieving the process conditions based on the process conditions.

Because the process steps of the standard operation flow correspond to the process conditions, whether the public and auxiliary equipment is needed for each production task can be determined based on the process conditions. The determination mode starts from a standard operation flow, so that whether each production task needs to use public and auxiliary equipment or not can be accurately determined, and the accuracy of the scheme is improved.

Wherein the process conditions are, for example, whether vacuum, temperature range, etc. conditions are required. The parameters may be setting parameters of the stirring device, such as rotational speed, stirring time, etc.

Optionally, the recipe for each process step may also be included in a standard operational flow. The formula is the type and amount of materials to be added. The specific implementation of the process conditions or parameters and recipe is not limited here.

Since the process conditions define the execution environment of the process steps, which often requires maintenance by the public and auxiliary equipment, it is possible to determine whether the public and auxiliary equipment is needed after the process conditions are defined.

For example, if the male auxiliary equipment is a vacuum equipment, then in the event that the process conditions are such that a vacuum is required, this is an indication that the male auxiliary equipment is required to be used. The examples herein are for ease of understanding only and should not be construed as limiting the application.

The production tasks and the standard operation flow associated with each production task can be obtained in advance and stored in a storage medium, and can be directly called when the production tasks are needed to be used. Or the production tasks and the standard operational flows associated with each production task may be obtained from production facilities in the plant.

In a second embodiment, determining whether the shop floor needs to use the auxiliary equipment within a preset period from the current moment includes determining whether a request opening instruction sent by automatic production equipment in the shop floor is received, wherein the receipt of the request opening instruction indicates that the shop floor needs to use the auxiliary equipment, and the non-receipt of the request opening instruction indicates that the shop floor does not need to use the auxiliary equipment.

And determining whether the public and auxiliary equipment is needed to be used in the workshop by judging whether the automatic production equipment sends a request starting instruction or not. Therefore, whether the public auxiliary equipment is needed in the workshop or not and the total demand load of the public auxiliary equipment can be determined more simply and conveniently.

The request opening instruction also needs to include a demand load corresponding to the production equipment, so that the total demand load of the workshops to the public and auxiliary equipment can be determined later.

In the third embodiment, when the public and auxiliary equipment is environment-type public and auxiliary equipment, the method for determining whether the public and auxiliary equipment is needed to be used in the workshop in the preset period from the current moment may be that all production tasks in the workshop are acquired in the preset period from the current moment. It is then determined, for each production task, whether the production task requires the use of a public and auxiliary device, for the type of product produced by the production task.

Wherein, the production task is clear in the foregoing description, and is not repeated here for the sake of brevity.

The environment of the production process is usually provided by the public and auxiliary equipment, as the environment required for the production process of different products is different. Therefore, the type of the product produced by the production task can know what type of public and auxiliary equipment is needed to be used by the production task, so that whether the public and auxiliary equipment is needed to be used by the production task can be determined.

For example, if the product created by the production task is an adhesive, it may be determined that the production process of the product requires control of humidity. Thus, it can be determined that the production task requires the use of a common auxiliary device for controlling humidity. The examples herein are for ease of understanding only and should not be construed as limiting the application.

Optionally, a corresponding relation table of the product type and the public auxiliary equipment type may be stored in advance, and under the condition that whether the production task needs to use the public auxiliary equipment or not needs to be determined, the public auxiliary equipment corresponding to the product type may be found out by determining the product type produced by the production task and then from the pre-stored corresponding relation table.

Wherein, the same product type can correspond to a plurality of different public and auxiliary devices.

If it is determined that the plant does not need the auxiliary equipment, all the auxiliary equipment can be turned off.

And S200, if the workshop needs to use the public auxiliary equipment, determining the total required load of the workshop on the public auxiliary equipment.

The total demand load of the workshops on the public and auxiliary equipment is determined, and the following several implementation methods are available.

In the first embodiment, if the standard operation flow associated with each production task is obtained before, the mode of determining the total demand load of the workshop on the public auxiliary equipment may be to determine, for each production task in a preset time period, the demand load of the production task on the public auxiliary equipment based on the process conditions included in the standard operation flow associated with the production task. The total demand load is then derived based on all of the determined demand loads.

Because the demand load of different production tasks on the public and auxiliary equipment can be different, the demand load corresponding to each production task is determined according to the process conditions, so that the obtained demand load of each production task is more accurate. And further, the total demand load obtained finally is more accurate.

Alternatively, the method may be that in a standard operation flow, a demand load is marked for each process condition in advance, and in the method of determining the demand load of the production task on the public and auxiliary equipment based on the process condition included in the standard operation flow associated with the production task, the demand load corresponding to the process condition may be obtained directly from the process condition.

Alternatively, the required load level may be marked for each process condition in advance in the standard operation flow, and accordingly, the required load of the production task on the public auxiliary equipment may be determined based on the process condition included in the standard operation flow associated with the production task.

The number and names of the demand load levels may be set according to actual demands, which are not limited herein.

The demand load can be represented by a numerical value, and correspondingly, the load capacity of the public auxiliary equipment can also be represented by a numerical value.

Or the demand load can be represented by grades, and the load capacity of the public auxiliary equipment required by the demand load of different grades is different. In this case, the load capacity of the male and female devices may be expressed as the number of required loads that can support the respective levels.

The level of the demand load may be divided according to actual demands, and the specific division manner is not limited herein.

For example, if the demand load can be divided into two levels of low load and high load, the load capacity of the male and female devices can be expressed as that the first male and female device can support two high loads at the same time or five low loads at the same time.

In the second embodiment, if the request start instruction sent by the automatic production equipment in the workshop is received, whether the workshop needs to use the public and auxiliary equipment or not is determined in a preset period from the current moment. The specific way of determining the total demand load of the workshops on the public and auxiliary equipment may be to analyze all the request opening instructions received in the preset period from the current moment to obtain the total demand load.

Because the request opening instruction already comprises the demand load, a plurality of demand loads can be obtained by analyzing each request opening instruction.

Optionally, after the demand load corresponding to each request opening instruction is obtained by parsing, the total demand load may be obtained by summing the demand loads corresponding to each request opening instruction, so as to obtain the total demand load.

Or after the demand load corresponding to each request opening instruction is obtained through analysis, the mode of obtaining the total demand load can be that the demand load corresponding to each request opening instruction is summed, and the redundant load is added on the basis of the summation value to obtain the total demand load. The redundant load is used for providing redundancy for the obtained total demand load so as to ensure that the total demand load can meet the demands of all production tasks of the workshop on the public and auxiliary equipment within the preset time period.

And S300, determining the starting quantity of the public auxiliary equipment required to be started based on the total demand load.

The starting quantity is the minimum quantity which meets the requirement that the total load of the public and auxiliary equipment is larger than or equal to the total demand load.

In one embodiment, if the demand load is represented by a numerical value, the total demand load and the load capacity of the auxiliary equipment are both represented by numerical values. And determining the starting quantity of the public and auxiliary equipment to be started only by enabling the sum of the loads of the public and auxiliary equipment to be larger than the total required load, wherein the quantity of the public and auxiliary equipment to be summed is the starting quantity.

For example, if the total required load is 33 and the load capacity of each of the auxiliary devices is 5, it may be determined that the number of required starts of the auxiliary devices is 7. The examples herein are for ease of understanding only and should not be construed as limiting the application.

In one embodiment, because the load capacities of different male and female devices may be different, a specific manner of determining the number of starts that need to start the male and female devices based on the total required load may be to first obtain the load capacity of each male and female device. And then determining that the sum of the load capacities is greater than or equal to the total demand load, and the plurality of public auxiliary equipment with the smallest difference with the total demand load is the public auxiliary equipment to be started, wherein the number of the public auxiliary equipment to be started is the starting number.

For example, if the total demand load is 33, and the load capacity of the male auxiliary equipment 1 is 10, the load capacity of the male auxiliary equipment 2 is 8, the load capacity of the male auxiliary equipment 3 is 15, and the load capacity of the male auxiliary equipment 4 is 9. Since the sum of the load capacities of the male slave device 1, the male slave device 2, and the male slave device 3 is 33, which is equal to the total required load, the number of starts is determined to be 3. And the public auxiliary equipment to be started is public auxiliary equipment 1, public auxiliary equipment 2 and public auxiliary equipment 3. The examples herein are for ease of understanding only and should not be construed as limiting the application.

In one embodiment, if the total required load corresponding to the auxiliary equipment is greater than the total load of all the auxiliary equipment, part of the production tasks in the workshop are postponed and executed, so that the total required load of the production tasks which are not postponed and executed on the auxiliary equipment is smaller than or equal to the total load.

If the total required load corresponding to the public auxiliary equipment is larger than the total load of all the public auxiliary equipment, the public auxiliary equipment cannot bear all production tasks of the current workshop. Accordingly, it is necessary to delay execution of a part of the production task to prevent failure of the production task due to insufficient capabilities of the male and female devices.

Wherein, the production task can be randomly selected to be executed in a postponed way. Or the priority of the production task is preset, and the production task with the later priority is delayed until the total required load of the rest production tasks on the public and auxiliary equipment is less than or equal to the total load.

The specific time length of the delay can be set according to actual requirements, for example, the length of the preset time period can be delayed. Or a delay time is preset, and the production task needing to be delayed is delayed by the delay time. Wherein the delay time is longer than the length of the preset time period.

And S400, starting the public and auxiliary equipment matched with the starting quantity.

In one embodiment, if the load capacity of the same type of public and auxiliary equipment is the same, the public and auxiliary equipment matched with the starting number can be started randomly from all the public and auxiliary equipment. Or selecting from high to low according to the preset public and auxiliary equipment priority.

If the load capacities of the same type of public and auxiliary devices may be different, in S300, it is already confirmed that the public and auxiliary devices to be started (that is, the plurality of public and auxiliary devices with the sum of the load capacities being equal to or greater than the total required load and the difference between the total required load and the sum of the load capacities being the minimum) are already started, and then all the public and auxiliary devices to be started are started.

In one embodiment, if the standard operation flow associated with each production task is obtained, and the process steps of the standard operation flow further include the start time of the execution condition, the specific manner of starting the public and auxiliary equipment matched with the number of starts may be that the earliest start time in all the process steps requiring the public and auxiliary equipment is determined to be the target start time first. And starting the public and auxiliary equipment matched with the starting quantity by taking the target starting time as a base point in advance, wherein the designated time is the time required by the public and auxiliary equipment from starting to stable running.

Because the public auxiliary equipment needs a certain time from starting to stable operation, under the condition that the starting time of the process condition can be known through the process steps, the public auxiliary equipment can be started in advance, so that the public auxiliary equipment is in a stable operation state when the public auxiliary equipment is needed for assistance of the production task, and the process condition can be met stably. The condition that the production task fails due to the fact that the operation of the public and auxiliary equipment is unstable in the just-started stage and stable assistance cannot be provided for the production task is avoided, and the process condition is not met is avoided.

The start time of the execution condition, that is, the start time point of the period of time in which the execution condition needs to be satisfied.

For example, if a vacuum environment is desired to be satisfied at 07:50, 07:50 is the start time of the process conditions (satisfying the vacuum environment), and examples herein are for ease of understanding only and should not be taken as limiting the application.

The implementation manner of the startup and startup number matching public and auxiliary devices is clear in the foregoing description, and is not repeated here for brevity.

For ease of understanding, the description will be given taking as an example that there are three process steps requiring vacuum equipment. If the vacuum environment (process condition) needs to be satisfied at 07:50 (start time) in process step1, the vacuum environment (process condition) needs to be satisfied at 07:55 (start time) in process step 2, and the vacuum environment (process condition) needs to be satisfied at 07:57 (start time) in process step 3. It can be confirmed that 07:50 is the earliest start time and thus the target start time is 07:50.

If the specified duration is 10 minutes (i.e., the vacuum apparatus takes 10 minutes from start-up to smooth running), then the vacuum apparatus matching the number of starts needs to be started at 07:40.

The examples herein are for ease of understanding only and should not be construed as limiting the application.

In one embodiment, if the standard operation flow associated with each production task is obtained, and the existing process steps further include designating the public auxiliary equipment, the specific implementation manner of starting the public auxiliary equipment matched with the starting number may be that the public auxiliary equipment matched with the starting number and including the designated public auxiliary equipment is started.

Optionally, if the load capacities of the public and auxiliary devices of the same type are the same, after determining the starting number, determining one public and auxiliary device as the designated public and auxiliary device, and randomly selecting the rest other public and auxiliary devices or selecting according to the preset public and auxiliary device priority.

Alternatively, if the load capacities of the same type of public and auxiliary devices may be different, the specific manner of determining the number of starts that need to start the public and auxiliary devices based on the total required load may be to first obtain the load capacity of each public and auxiliary device. And then determining that the sum of the load capacities is greater than or equal to the total demand load, and the public and auxiliary equipment with the smallest difference with the total demand load, including the appointed public and auxiliary equipment, is the public and auxiliary equipment to be started, wherein the number of the public and auxiliary equipment to be started is the starting number. Correspondingly, the mode of starting the public auxiliary equipment matched with the starting quantity is that all public auxiliary equipment to be started is started.

In one embodiment, if the standard operation flow associated with each production task is obtained, and the process steps further include the start time and the shut-down time of the public and auxiliary equipment, the standard operation flow associated with each production task in the workshop can also be obtained in the next preset time period. And then determining the time difference between the closing time of the public auxiliary equipment in the preset time period and the starting time of the public auxiliary equipment in the next preset time period based on the standard operation flow corresponding to the preset time period and the standard operation flow corresponding to the next preset time period.

If the time difference is smaller than a preset time difference threshold, the public and auxiliary equipment is not closed at the closing time in the preset time period.

If the time difference is greater than or equal to a preset time difference threshold, closing the public and auxiliary equipment at the closing time within a preset time period.

The more frequently the switching frequency of the public auxiliary equipment is, the lower the service life of the public auxiliary equipment is. Therefore, if the time difference between the front and the rear is smaller than the preset time difference threshold, the public and auxiliary equipment is not closed. Otherwise, the public and auxiliary equipment is closed. To balance the service life of the public and auxiliary equipment and the energy consumption of the public and auxiliary equipment.

The ending time point of the preset time period from the current moment is the starting point of the next preset time period.

Optionally, if there are multiple start-up times in the next time period, determining the earliest start-up time as the final start-up time. Correspondingly, if a plurality of closing times exist in the preset time period, determining the latest closing time as the final closing time.

In one embodiment, if all production tasks in the workshop are executed and completed within a preset time period, all public and auxiliary equipment is closed.

And when the fact that all production in the workshop is executed within the preset time period is determined to be completed, the fact that the public auxiliary equipment does not need to be continuously started is indicated, and therefore all the public auxiliary equipment is directly closed, and energy waste caused by the fact that the public auxiliary equipment is empty is prevented.

It is then determined whether the total load of the vacuum apparatus can bear the total demand load. If so, determining a minimum number of starts meeting the total demand load, and starting the vacuum equipment matched with the number of starts.

If the total load of the vacuum equipment is smaller than the total demand load, the process 1 of the production line 1 may be performed one process later, that is, the process 1 of the production line 1 and the process 2 of the production line 2 and the process 2 of the production line 3 are simultaneously performed, and accordingly, the other processes of the production line 1 may be performed one process later (or the process 1 of the production line 3 may be performed one process later).
