The following will describe in detail.

Example 1

Referring to fig. 1, fig. 1 is a schematic flow chart of a PLC centralized control method applied to a centralized component of a battery cell according to an embodiment of the present invention. The PLC centralized control method applied to the electrical core formation component capacity described in fig. 1 can be applied to a PLC centralized control system of the electrical core formation component capacity, can also be applied to a local server or a cloud server of the PLC centralized control of the electrical core formation component capacity, and can also be applied to a PLC centralized control of the electrical core formation component capacity. As shown in fig. 1, the PLC centralized control method applied to the cell formation composition may include the following operations:

101. and reading at least one operation request, and determining the PLC to be controlled corresponding to each operation request.

In an embodiment of the present invention, optionally, each operation request is an operation request for indicating that a corresponding control operation is performed on the PLC.

In the embodiment of the present invention, alternatively, PLCs corresponding to different operation requests may be the same PLC, and the number of PLCs corresponding to one operation request is one.

In the embodiment of the present invention, optionally, for each operation request, determining the PLC to be controlled corresponding to the operation request may include:

For each operation request, determining request key information in the operation request, wherein the request key information comprises one or more of serial number information, model information, brand information, production information, memory information, capacity information and memory information of the PLC to be controlled corresponding to the operation request;

for each operation request, determining the PLC to be controlled which is matched with the request key information of the operation request.

Therefore, the to-be-controlled PLC corresponding to each operation request can be determined by determining the request key information in each operation request, which is beneficial to improving the accuracy and reliability of determining each to-be-controlled PLC and the intelligence of determining each to-be-controlled PLC.

102. And for each PLC to be controlled, generating a message queue of the PLC to be controlled according to all operation requests corresponding to the PLC to be controlled.

In the embodiment of the invention, optionally, the message queue of each to-be-controlled PLC includes all operation requests required to be executed by the to-be-controlled PLC; further, all operation requests to be executed by each to-be-controlled PLC included in the message queue of the to-be-controlled PLC are arranged according to a preset time sequence order. For example, when the operation request to be executed by a certain PLC to be controlled includes an operation request a and an operation request B, and the receiving time of the operation request a received by the PLC to be controlled is 03:00:01, and the receiving time of the operation request B received by the PLC to be controlled is 03:00:06, the execution sequence of the operation request a in the message queue of the PLC to be controlled is earlier than the execution sequence of the operation request B, that is, the operation request a is executed first and then the operation request B is executed.

103. And for each PLC to be controlled, based on the message queue of the PLC to be controlled and each operation request included in the message queue of the PLC to be controlled, performing serial writing operation on the PLC to be controlled so as to write each operation request into the PLC to be controlled.

In the embodiment of the present invention, optionally, when each PLC to be controlled performs a serial write operation, the number of operation requests written by each PLC to be controlled is one.

In the embodiment of the present invention, further optionally, for different PLCs to be controlled, each PLC to be controlled can simultaneously perform serial write operation on each operation request included in the message queue of the PLC to be controlled, that is, serial write operation on the operation request can be simultaneously performed between different PLCs to be controlled, and each operation request corresponding to the same PLC to be controlled cannot simultaneously perform write operation on the operation request.

In an embodiment of the present invention, optionally, for example, a specific manner of performing a serial write operation on each PLC to be controlled to write each operation request to the PLC to be controlled may be: firstly, reading a data area to be written, then, modifying the read data according to written points, then, writing back to the data area corresponding to the PLC, and then, polling to read the corresponding data area until the data of the data area is consistent with the data expected to be written, wherein the corresponding data area is the data area in the PLC to be controlled, and then, the next writing operation can be carried out. Therefore, the occurrence of error coverage operation when a plurality of control terminals perform writing operation on the same PLC can be avoided, the number of corresponding operation requests when the same PLC performs data writing operation is one, the improvement of the accuracy and the reliability when the data writing operation is performed is facilitated, the data writing operation can be performed in combination with time sequence, and the accuracy and the reliability when the data writing operation can be further improved.

It can be seen that implementing the centralized control method for the chemical composition PLC applied to the electrical core described in fig. 1 can read at least one operation request and determine the PLC to be controlled corresponding to each operation request, generate a message queue for each PLC to be controlled according to the operation request corresponding to each PLC to be controlled, perform serial write operation on each PLC to be controlled based on the message queue and each operation request of each PLC to be controlled, so as to write each operation request to each PLC to be controlled, when a plurality of operation requests exist in the same PLC to be controlled, perform serial write operation on the PLC to be controlled when a plurality of ends exist in the same PLC to be controlled, sequentially write each operation request corresponding to the PLC to be controlled into the PLC to be controlled, compared with the condition that when a plurality of operation requests exist in the same PLC in the prior art, sequentially perform serial write operation on each operation request, ensure that each operation request can be correctly written to each PLC to be controlled when a plurality of operation requests exist in the same PLC to be controlled, can be controlled in uniform, can prevent the same PLC from being controlled from being subjected to control data from being uniformly, and can further control the accuracy in a unified manner, and can be beneficial to improving the accuracy of the control of the accuracy of the PLC by the centralized control program and the control of the PLC.

In an alternative embodiment, after determining, for each operation request, the PLC to be controlled corresponding to the operation request, the method further includes:

judging whether target PLCs exist in all PLCs to be controlled, wherein the number of operation requests corresponding to the target PLCs is lower than a preset number threshold;

when judging that the target PLC does not exist in all the PLCs to be controlled, triggering and executing the operation of generating a message queue of each PLC to be controlled according to all operation requests corresponding to the PLC to be controlled.

In this optional embodiment, optionally, determining whether the target PLC exists in all PLCs to be controlled may include:

for each PLC to be controlled, determining the number of operation requests corresponding to each PLC to be controlled;

judging whether the target number exists in the number of operation requests corresponding to all PLCs to be controlled, wherein the target number is 1;

when the number of the operation requests corresponding to all the PLCs to be controlled is judged to be the target number, determining the PLCs to be controlled corresponding to the target number as the target PLCs, and determining that the target PLCs exist in all the PLCs to be controlled;

And when the fact that the target number does not exist in the number of the operation requests corresponding to all the PLCs to be controlled is judged, determining that the target PLCs do not exist in all the PLCs to be controlled.

In this alternative embodiment, the preset number threshold may alternatively be 1.

In this optional embodiment, optionally, the number of target operation requests corresponding to the target PLC is one; further optionally, generating the target write data according to the target operation request corresponding to the target PLC may include: determining request destination information of a target operation request according to a target operation request corresponding to a target PLC, wherein the request destination information comprises request operation information, request operation time information, request data information, request writing data area and request data type information; and generating target write data according to the request destination information. Further, the data type of the target write data matches the data type corresponding to the requested write data area.

It can be seen that implementing this alternative embodiment can determine whether there is a target PLC in all PLCs to be controlled in all the PLCs to be controlled, if there is a target PLC, generating target write data according to a target operation request corresponding to the target PLC and executing a corresponding data write operation, so as to write the target operation request to the target PLC, if there is no target PLC, executing an operation of generating a message queue of each PLC to be controlled according to all the operation requests corresponding to each PLC to be controlled, and when it is determined that PLCs to which the operation request belongs are different and there are target PLCs to which the number of operation requests to be written is smaller than a preset threshold, executing parallel data write operations between a plurality of different PLCs is performed when it is determined that the operation requests belong to the target PLCs that the operation requests are different.
