Description

Technical Field

[0001] The present invention relates to the technical field of industrial automation, and in particular to a method, system, electronic equipment and storage medium for executing a sequential control program. Background Art

[0002] If a control system can be decomposed into several independent control actions, and these actions must be executed strictly in a certain order to ensure the normal operation of the production process, then this kind of control of the system is called sequential control, and the corresponding control program is a sequential control program. In the actual production process, there are the following situations: the control objects of multiple sequential control programs include the same common equipment and different independent equipment. Because the calling time of multiple sequential control programs for common equipment is different, the start and stop time of the common equipment cannot meet the requirements of each sequential control program.

[0003] In the prior art, there are the following processing methods for the above situation: 1. Sequential control program startup interlock. When multiple sequential control programs need to call a common equipment group, when one of the sequential control programs calls the common equipment group, the remaining sequential control programs are locked and cannot be started, so as to avoid conflicts in the use of the common equipment group by multiple sequential control programs. 2. Sequential control programs wait in a queue. When multiple sequential control programs are started, the execution actions of the sequential control are executed in sequence according to the time sequence of the sequential control program startup, so as to avoid conflicts in the use of the common equipment group by multiple sequential control programs. 3. Multiple sequential control programs run at the same time. When one of the sequential control programs ends, the running status of other sequential control programs is judged. If other sequential control programs are still running, the common equipment will not be stopped at this end.

[0004] As mentioned above, when the interlocking and queuing methods are used to handle the above scenarios, the sequential control can only be executed in a staggered manner, which greatly prolongs the entire production time and reduces the production efficiency. If the method of running while judging the running status of other sequential control programs in real time is adopted, it will occupy additional programming resources of the sequential control program.

DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] Example 1 like Figure 1 The figure shows a working scenario applicable to the present embodiment: the raw materials in the storage tank sequentially pass through the bottom valve, the delivery pump and the valve into the reactor, wherein there are three groups of valves and reactors, that is, one group of bottom valves and the delivery pump corresponds to three groups of valves and reactors. According to the production process requirements, the bottom valve, the delivery pump and the valve need to be opened in sequence, so a sequential control program is used to operate the equipment, wherein the bottom valve and the delivery pump are common equipment, and the three valves are independent equipment, so three sequential control programs are required to operate the three groups of equipment respectively, namely: bottom valve, delivery pump, valve 1; bottom valve, delivery pump, valve 2; bottom valve, delivery pump, valve 3. In order to avoid conflicts among the three sequential control programs when calling common equipment, the prior art generally adopts the interlocking and queuing method between the three sequential control programs for staggered execution, which affects production efficiency; or adopts the method of running while judging the running status of other sequential control programs in real time, which will occupy additional programming resources of the sequential control program. For this reason, if Figure 2 As shown, this embodiment provides a method for executing a sequential control program, comprising the following steps: Step 102, receiving the start and stop signals of the sequential control programs of all independent devices at the same level, and generating corresponding common program start and stop signals respectively. Among them, the start and stop signals of the sequential control programs are used to operate the start and stop of a group of equipment. Taking the above scenario as an example, there are three sequential control programs in total, and a group of equipment includes a bottom valve, a delivery pump and one of the valves. No matter which group of equipment is started or stopped, the common equipment therein, that is, the bottom valve and the delivery pump, will be involved, and according to the production process requirements, the common equipment of the upper level needs to be opened before the independent equipment of the lower level. Therefore, whenever a sequential control program start and stop signal is received, a common program start and stop signal is generated to operate the common equipment of the upper level.

[0020] Step 104, based on the OR operation results of all public program start and stop signals of the same level, a public program start and stop operation result signal is generated. The OR operation result of all public program start and stop signals means that when there is a start signal, the OR operation result is start; when all signals are stop signals, the OR operation result is stop. That is, among all public program start and stop signals, as long as there is a start signal, the generated public program start and stop operation result signal is a start signal, otherwise the generated public program start and stop operation result signal is a stop signal.

[0021] Step 106, based on the public program start-stop operation result signal, control the start-stop of the public equipment at the previous level, and generate a public equipment start-stop status signal. Taking the above scenario as an example, if the public program start-stop operation result signal is a start signal, it means that at least one valve needs to be opened, then the public equipment at the previous level is controlled to start, that is, the bottom valve and the delivery pump, and the public equipment start-up status signal is generated at the same time; of course, if the public equipment is already in the start-up state, it can be maintained in the start-up state, and the public equipment start-up status signal is also maintained. If the public program start-stop operation result signal is a stop signal, it means that all three valves are closed, then the public equipment at the previous level also needs to be stopped, and the public equipment stop status signal is generated at the same time.

[0022] Step 108, based on the start and stop signal of the sequential control program and the start and stop status signal of the upper-level common equipment, control the start and stop of the independent equipment. Specifically, the start status signal of the upper-level common equipment can be triggered by the start signal of the current sequential control program, or by other previous start signals of the sequential control program. For example, if all the equipment is in a stopped state, and the sequential control program start signal of valve 1 is received at this time, then after the above steps, the common equipment will be controlled to start first, and then the common equipment start status signal will be generated, and then valve 1 will be opened. If the bottom valve, the delivery pump and valve 2 are working, then the common equipment start status signal already exists at this time, then when the sequential control program start signal of valve 1 is received at this time, valve 1 can be directly opened.

[0023] Step 108 specifically includes: When the sequential control program start signal and the upper level common equipment start status signal are received, the independent equipment is controlled to start. Taking the above scenario as an example, when the sequential control program start signal of valve 1 and the common equipment start status signal are received, valve 1 is opened, and the same applies to other valves.

[0024] When a stop signal of the sequence control program is received, the control of the independent device stops. For example, when a stop signal of the sequence control program related to valve 1 is received, valve 1 is directly closed, and the same applies to other valves.

[0025] In summary, still taking the above scenario as an example, the overall working logic of this embodiment is as follows: When receiving the start signal of the sequence control program related to valve 1, if the start-stop status signal of the common equipment is a start signal at this time, it means that the bottom valve and the transmission pump are in the start state, and valve 1 is directly opened; if the start-stop status signal of the common equipment is a stop signal at this time, then according to the start-stop operation result signal of the common program, the bottom valve and the transmission pump are started first, and the start-stop status signal of the common equipment becomes a start signal, and then valve 1 is opened. The same applies to other valves.

[0026] When receiving the stop signal of the sequence control program related to valve 1, directly close valve 1; if the start-stop operation result signal of the common program is a start signal at this time, it means that there are other valves in the open state, and keep the bottom valve and the delivery pump in the started state; if the start-stop operation result signal of the common program is a stop signal at this time, it means that all valves are in the closed state, and close the bottom valve and the delivery pump. The same applies to other valves.

[0027] In this way, as long as any one of the sequential control programs is started, the common equipment will be started; as long as any one of the sequential control programs has not ended, the common equipment will not stop. Therefore, multiple sequential control programs can be carried out synchronously to effectively ensure production efficiency. Moreover, this embodiment can be implemented only through the transmission of signals, without the need to judge the program, which not only saves programming resources but also improves the efficiency of program execution. It should be noted that the above scenario only shows a relatively simple situation, that is, there are three parallel valves with the same upper-level common equipment. If the number of valves is 100, then when one valve is closed, the prior art needs to judge the status of the remaining 99 valves, then the occupied programming resources will increase sharply, and the program execution efficiency will also drop sharply. The method of this embodiment can effectively avoid this problem.

[0028] Example 2 like Figure 3 The figure shows a working scenario applicable to this embodiment. The difference from the first embodiment is that the common equipment in this embodiment is at the lower level, while the three parallel independent equipment are at the upper level. According to the production process requirements, the independent equipment needs to be started first, and then the common equipment. Figure 4 As shown, this embodiment provides a method for executing a sequential control program, comprising the following steps: Step 202, receiving the sequential control program start and stop signals of all independent devices at the same level, controlling the start and stop of the corresponding independent devices respectively, and generating corresponding public program start and stop signals respectively. Since the independent devices are at the upper level, they need to be started and stopped first, without waiting for the public devices at the lower level to start and stop first. After any independent device is started, the public devices at the lower level need to be started; after any independent device is stopped, it may affect the status of the public devices at the lower level; therefore, it is necessary to generate public program start and stop signals for operating the public devices.

[0029] Step 204, based on the OR operation results of all utility start / stop signals of the same level, a utility start / stop operation result signal is generated. That is, when any independent device is started, there is a utility start signal, the OR operation result is the start signal, and the corresponding utility start / stop operation result signal is the start signal; when all independent devices are stopped, there is only a utility stop signal, the OR operation result is the stop signal, and the corresponding utility start / stop operation result signal is the stop signal.

[0030] Step 206, based on the utility program start-stop operation result signal, control the start-stop of the next level of utility equipment.

[0031] Since the device startup sequence of this embodiment is consistent with the output direction of the OR operation result, there is no feedback to the superior, so this embodiment is simpler than the embodiment 1. The overall working logic of this embodiment is as follows: When receiving the sequence control program start signal of the independent device 1, the independent device 1 is directly started; then, since the independent device 1 is started, the public program start-stop operation result signal at this time must be a start signal, starting the public device or keeping the public device started. The same applies to other independent devices.

[0032] When a stop signal of the sequential control program related to independent device 1 is received, independent device 1 is stopped directly; if the public program start-stop operation result signal at this time is a start signal, it means that other independent devices are running, and the public device is kept started; if the public program start-stop operation result signal at this time is a stop signal, it means that all independent devices have been stopped, and the public device is shut down.

[0033] Example 3 like Figure 5 As shown, this embodiment provides a sequential control program execution system suitable for Figure 1 In the working scenario shown, the system of this embodiment includes: The common program module is used to receive the common program start and stop operation result signal, control the start and stop of the common equipment, and output the common equipment start and stop status signal to all the independent program modules of the next level; The independent program module is used to receive the start and stop signals of the sequential control program and the start and stop status signals of the common equipment output by the upper-level common program module, control the start and stop of the independent equipment, and output the common program start and stop signals to the OR logic module; The OR logic module is used to receive all the utility program start and stop signals of the same level, and after OR logic operation, output the utility program start and stop operation result signal to the utility program module of the upper level.

[0034] Specifically, there are two or more independent program modules, which respectively control each or each group of independent devices, and each independent program module includes: An independent program startup unit, used to control the startup of the independent device when receiving a sequential control program startup signal and a common device startup state signal output by the upper-level common program module; An independent program stop unit, used to control the independent device to stop when receiving a sequential control program stop signal; The independent program feedback unit is used to output a common program start / stop signal to the OR logic module when receiving a sequential control program start / stop signal.

[0035] by Figure 1 Taking the scenario shown as an example, the working principle of this embodiment is as follows: When independent program module 1 receives the sequential control program start signal, independent program module 1 immediately generates a common program start signal and outputs it to the OR logic module; the OR logic module obtains the common program start-stop result signal as the start signal after OR operation, and outputs it to the common program module; the common program module receives the start signal, immediately controls the bottom valve and the transmission pump to start, and generates a common equipment start status signal, and outputs it to independent program module 1, independent program module 2 and independent program module 3; at this time, independent program module 1 receives the common equipment start status signal and controls valve 1 to open. If independent program module 2 receives the sequential control program start signal later, since independent program module 2 has received the common equipment start status signal, it can directly control valve 2 to open.

[0036] When the independent program module 1 receives the sequential control program stop signal, the independent program module 1 directly controls the valve 1 to close, and generates a common program stop signal and outputs it to the OR logic module; if there are other valves in the open state at this time, the operation result of the OR logic module is still the start signal, then the common program module will not control the bottom valve and the transmission pump to stop after receiving the signal; if all valves are closed at this time, the operation result of the OR logic module is a stop signal, then the common program module will control the bottom valve and the transmission pump to stop after receiving the signal.

[0037] This embodiment divides the control logic of the public equipment independently and writes it into a public program module independently. It does not directly participate in the sequential control program. The public program module is started only by the start signal output by the independent program module. The overall structure design is simple and the operation is efficient. The use of this embodiment can effectively improve production efficiency and save programming resources.

[0038] Example 4 like Figure 6 As shown, this embodiment provides a sequential control program execution system suitable for Figure 3 The working scenario shown, the system diagram of this embodiment includes: The utility program module is used to receive the utility program operation result signal and control the start and stop of the utility equipment; An independent program module is used to receive a sequential control program start and stop signal, control the start and stop of an independent device, and output a common program start and stop signal to an OR logic module; The OR logic module is used to receive all the utility program start / stop signals of the same level, and after OR logic operation, output the utility program start / stop operation result signal to the utility program module of the next level.

[0039] There are two or more independent program modules, which respectively control each or each group of independent devices.

[0040] by Figure 3 Taking the scenario shown as an example, the working principle of this embodiment is as follows: When the independent program module 1 receives the sequential control program start signal, it directly controls the independent device 1 to start. At the same time, the independent program module 1 generates a public program start signal and outputs it to the OR logic module; the OR logic module obtains the public program start and stop result signal as the start signal through OR operation, and outputs it to the public program module; the public program module receives the start signal and immediately controls the public device to start.

[0041] When the independent program module 1 receives the sequential control program stop signal, the independent program module 1 directly controls the valve 1 to close, and generates a common program stop signal and outputs it to the OR logic module; if there are other independent devices running at this time, the operation result of the OR logic module is still the start signal, then the common program module will not control the common device to stop after receiving the signal; if all independent devices have stopped at this time, the operation result of the OR logic module is a stop signal, then the common program module will control the common device to stop after receiving the signal.
