[0002] Energy storage valve control systems usually adopt a multi-board design (for example, control board, interface board, input and output board, display panel, etc.), and each board may have different functions or architectures. The application software configured on these boards can run based on the operating system or directly on the processor. The physical communication interface between boards may be a point-to-point communication bus interface or a shared bus interface, such as an Ethernet interface, RS485 interface, Controller Area Network (CAN) interface, Low-Voltage Differential Signaling (LVDS) interface, etc.

[0003] Currently, the communication method between boards is usually based on a physical signal interface driven by the same operating system, which has poor portability, scalability and flexibility. Summary of the invention

[0005] A first aspect of an embodiment of the present application provides a communication method, which is implemented based on a communication system running on a board, wherein the communication system includes a driver layer, an operating system layer, and an application layer, and further includes a unified system communication interface layer established between the operating system layer and the application layer, and the communication method includes:

[0006] Opening, through a first process, a source port corresponding to the first process to obtain a first communication channel identifier, and writing first data into a first shared space according to the first communication channel identifier;

[0007] By means of an inter-board communication agent, a destination port corresponding to the inter-board communication agent is opened to obtain the first communication channel identifier, and the first data is read from the first shared space according to the first communication channel identifier;

[0008] By means of the inter-board communication agent, the port number of the destination port corresponding to the inter-board communication agent is written into the first data to generate first target data;

[0011] The unified system communication interface layer includes the inter-board communication agent, the destination port corresponding to the inter-board communication agent, and the source port corresponding to the first process.

[0012] In the first aspect, a communication method implemented based on a communication system running on a board is provided, a unified system communication interface layer is established between the operating system layer and the application layer of the communication system, and an inter-board communication agent based on the unified system communication interface layer is configured in advance in the unified system communication interface layer according to actual needs, and a communication channel identifier and a shared space are established according to the port number of each group of virtual ports (that is, the source port and the virtual port) to establish a mapping relationship between each group of virtual ports, so that when inter-board communication is required and the user does not know the address of the data recipient, it is not necessary to know the address of the data recipient, and only Based on the mapping relationship between each group of virtual ports, communication between different boards can be realized, and there is no restriction on the types of operating systems running on different boards. This inter-board communication method is transparent to users (user transparency means that users do not need to care about the specific communication implementation method, it is transparent and invisible to users, and users only need to use it). Based on this, by pre-establishing the mapping between different virtual ports, the data sender (that is, the first process) and the data receiver (that is, at least one other board) can be flexibly bound, so that different data routing can be performed, which can be applied to any board, with good portability, scalability and flexibility.

[0017] The communication method further comprises:

[0018] In the case where a plurality of first target data are generated by the inter-board communication agent, all the first target data are packaged and sent to the driver layer by the inter-board communication agent.

[0019] A second implementation of the first aspect, when there are multiple destination ports corresponding to the inter-board communication agent, based on the pre-established mutual mapping relationship between each destination port corresponding to the inter-board communication agent and a source port corresponding to a first process, the inter-board communication agent can generate multiple first target data according to the first data sent by multiple first processes, and package them to the driver layer, so as to be sent to other boards through the driver layer, thereby realizing unidirectional batch data communication between different boards.

[0023] By means of the inter-board communication agent, according to the port number of the destination port corresponding to the other inter-board communication agent, the source port corresponding to the inter-board communication agent is opened to obtain a second communication channel identifier, and the second data is written into the second shared space according to the second communication channel identifier;

[0108] Step S104, sending the first target data to the driver layer through the inter-board communication agent, and proceeding to step S105;

[0109] Step S105 : driving at least one physical communication interface of the board through the driver layer to send the first target data to the physical communication interface of at least one other board.

[0110] In the application, the port number of the destination port corresponding to the inter-board communication agent and the port number of the source port corresponding to other inter-board communication agents of other boards are set to be the same and globally unique in advance according to the actual needs of the user, so as to establish a mutual mapping relationship between the destination port corresponding to the inter-board communication agent and the source port corresponding to the other inter-board communication agents, so that after receiving the first target data carrying the port number of the destination port corresponding to the inter-board communication agent, the other boards can open the source ports corresponding to other inter-board communication agents with the mapping relationship according to the port number of the destination port corresponding to the inter-board communication agent, and send the first data to the other processes according to the correspondence between the source ports corresponding to the other inter-board communication agents and the destination ports corresponding to other processes running on the other boards.

[0111] In the application, the inter-board communication agent triggers the driver layer to drive at least one physical communication interface of the board to send the first target data to the physical communication interface of at least one other board, so as to realize one-to-one reception or one-to-multiple reception. When realizing one-to-multiple reception, each physical communication interface of the board sends the first target data to a physical communication interface on another board.

[0112] In one embodiment, before step S101, the following steps are included:

[0113] Through the inter-board communication agent, a globally unique first communication channel ID and a globally unique first shared space are established according to the port number of the source port corresponding to the first process and the port number of the destination port corresponding to the inter-board communication agent.

[0114] In the application, before the first inter-board communication is performed, the port number of the source port corresponding to the first process and the port number of the destination port corresponding to the inter-board communication agent are configured in advance according to the actual needs of the user through the inter-board communication agent, and then a globally unique first communication channel ID and a globally unique first shared space are established according to the port numbers of this group of virtual ports. The first communication channel ID is used to realize the mapping between the source port corresponding to the first process and the destination port corresponding to the inter-board communication agent, so that the first process can send the first data to the destination port corresponding to the mutually mapped inter-board communication agent after opening the corresponding source port. The specific implementation method is: the first process writes the first data into the first shared space according to the first communication channel ID, and the inter-board communication agent reads the first data from the first shared space according to the first communication channel ID, thereby realizing the communication between the first process and the inter-board communication agent, and then realizing the communication between the first process and other boards, and the scalability and flexibility are good.

[0115] In one embodiment, the inter-board communication agent corresponds to multiple destination ports, and each destination port corresponding to the inter-board communication agent is mapped to a source port corresponding to a first process;

[0116] The above communication method also includes the following steps for implementing the second unidirectional inter-board communication (specifically, a board sends data in batches unidirectionally to at least one other board):

[0117] In the case where a plurality of first target data are generated through the inter-board communication agent, all the first target data are packaged and sent to the driver layer through the inter-board communication agent.

[0118] In the application, when the number of destination ports corresponding to the inter-board communication agent is multiple, multiple first processes can simultaneously send data to the inter-board communication agent unidirectionally through the corresponding source ports. The principle of each first process sending data unidirectionally to the inter-board communication agent is the same as steps S101 to S103, which will not be repeated here. The inter-board communication agent can generate multiple first target data according to the first data sent by the multiple first processes, and then package all the first target data and send them to the driver layer, so as to send them to other boards through the driver layer, thereby realizing unidirectional batch data communication between different boards.

[0119] like Figure 3 As shown, the communication method provided in the embodiment of the present application further includes the following steps S201 to S204 for implementing the third type of unidirectional inter-board communication (specifically, a board unidirectionally receives data sent by at least one other board):

[0120] Step S201: drive the physical communication interface of the board to receive second target data sent by the physical communication interface of at least one other board through the driver layer, and then proceed to step S202.

[0121] In the application, the inter-board communication agent triggers the driver layer to drive at least one physical communication interface of the board to receive the second target data sent by the physical communication interface of at least one other board, so as to realize one-send-one-receive or multiple-send-one-receive. When multiple-send-one-receive is realized, each physical communication interface of the driver board receives the second target data sent by a physical communication interface on another board.

[0122] Step S202: Obtain and parse the second target data through the inter-board communication agent to obtain the port number and second data of the source port corresponding to other inter-board communication agents, and then proceed to step S203.

[0123] In the application, the port number of the source port corresponding to the inter-board communication agent and the port number of the destination port corresponding to other inter-board communication agents are set to be the same and globally unique in advance according to the actual needs of the user, so as to establish a mutual mapping relationship between the source port corresponding to the inter-board communication agent and the destination ports corresponding to the other inter-board communication agents. In this way, after the inter-board communication agent obtains the second data carrying the port number of the destination port corresponding to the other inter-board communication agent, it can open the source port corresponding to the inter-board communication agent with the mapping relationship according to the port number of the destination port corresponding to the other inter-board communication agent, and send the second data to the second process according to the correspondence between the source port corresponding to the inter-board communication agent and the destination port corresponding to the second process running on the board.

[0124] Step S203: Open the source port corresponding to the inter-board communication agent according to the port number of the source port corresponding to the other inter-board communication agent through the inter-board communication agent to obtain the second communication channel ID, and write the second data into the second shared space according to the second communication channel ID, and enter step S204;

[0125] Step S204: Open the destination port corresponding to the second process through the second process to obtain the second communication channel ID, and read the second data from the second shared space according to the second communication channel ID.

[0126] In the application, the second process can be any process running on the board that needs to receive data sent by other processes running on other boards. In advance, according to the actual needs of the user, a group of virtual ports, including the destination port corresponding to the second process and the source port corresponding to the inter-board communication agent, are configured at the USCI layer of the board through the inter-board communication agent. Then, the inter-board communication agent establishes a globally unique second communication channel ID and a globally unique second shared space according to the port numbers of the group of virtual ports, and the second communication channel ID is stored in the second shared space.

[0127] In the application, the process of the inter-board communication agent sending the second data to the second process unidirectionally is as follows:

[0128] The inter-board communication agent opens the source port corresponding to the inter-board communication agent according to the port number of the destination port corresponding to the other inter-board communication agents, reads the globally unique second communication channel ID from the second shared space, and writes the second data into the second shared space according to the second communication channel ID;

[0129] The second process opens the destination port corresponding to the second process, reads the globally unique second communication channel ID from the second shared space, and reads the second data from the second shared space according to the second communication channel ID, thereby realizing the inter-board communication agent unidirectionally sending the second data to the second process.

[0130] In one embodiment, before step S201, the following steps are included:

[0131] Through the inter-board communication agent, a globally unique second communication channel ID and a globally unique second shared space are established according to the port number of the source port corresponding to the inter-board communication agent and the port number of the destination port corresponding to the second process.

[0132] In the application, before the third type of inter-board communication is performed, the port number of the destination port corresponding to the first process and the port number of the source port corresponding to the inter-board communication agent are configured in advance according to the actual needs of the user through the inter-board communication agent, and then a globally unique second communication channel ID and a globally unique second shared space are established according to the port numbers of this group of virtual ports. The second communication channel ID is used to realize the mapping between the destination port corresponding to the second process and the source port corresponding to the inter-board communication agent, so that the inter-board communication agent can send the second data to the destination port corresponding to the first process mapped to each other after opening the corresponding source port. The specific implementation method is: the inter-board communication agent writes the second data into the second shared space according to the second communication channel ID, and the second process reads the second data from the second shared space according to the second communication channel ID, thereby realizing the communication between the inter-board communication agent and the second process, and then realizing the communication between the second process and other boards, with good scalability and flexibility.

[0133] In one embodiment, the number of source ports corresponding to the inter-board communication agent is multiple, and each source port corresponding to the inter-board communication agent is mapped to a destination port corresponding to a second process;

[0134] The above communication method also includes the following steps for implementing the fourth type of unidirectional inter-board communication (specifically, a board receives data sent in batches unidirectionally by at least one other board):

[0135] When multiple packaged second target data are obtained through the inter-board communication agent, all the second target data are unpacked and parsed through the inter-board communication agent to obtain the port numbers of multiple destination ports corresponding to other inter-board communication agents and multiple second data.

[0136] In the application, when the number of source ports corresponding to the inter-board communication agent is multiple, the inter-board communication agent can receive multiple packaged second target data sent by at least one other board, and then unpack to obtain the port numbers and multiple second data of multiple destination ports corresponding to other inter-board communication agents, and then based on the mapping relationship between each group of virtual ports of different boards and the mapping relationship between each group of virtual ports of the same board, the multiple source ports corresponding to the inter-board communication agent can simultaneously send data unidirectionally to multiple second processes, thereby realizing unidirectional batch data communication between different boards. The principle of each source port of the inter-board communication agent sending data unidirectionally to the second process is the same as steps S203 and S204, which will not be repeated here.

[0137] In one embodiment, the second process and the first process can be the same process. Based on the above-mentioned steps of the first unidirectional inter-board communication and the fourth unidirectional inter-board communication, bidirectional communication between the same process in the board and the inter-board communication agent can be realized, and then bidirectional communication between the same process of the board and other boards can be realized.

[0138] In the application, the board communicates with other boards based on the above communication method. Figure 2 When the corresponding communication method sends data to at least one other board in one direction, the other board can use Figure 3 The corresponding communication method receives the data sent unidirectionally by the board; similarly, when the board adopts Figure 3 When the corresponding communication method receives data sent unidirectionally by at least one other board, the other boards can use Figure 2 The corresponding communication method sends data unidirectionally to the board.

[0139] based on Figure 1 , Figure 4 An exemplary diagram of a bidirectional communication architecture between two different boards is shown when the second process and the first process are the same process;

[0140] Among them, board 100 is Figure 1 The board in the corresponding embodiment;

[0141] In the board 200, the source port 235-1 corresponding to the inter-board communication agent 231 and the destination port 234-3 corresponding to the process 242 are mapped to each other, so as to realize the unidirectional data transmission from the inter-board communication agent 231 to the process 242;

[0142] The source port 234-4 corresponding to the process 242 and the destination port 235-2 corresponding to the inter-board communication agent 231 are mapped to each other, so as to realize the one-way data transmission from the process 241 to the inter-board communication agent 231;

[0143] The port number of the destination port 135-1 corresponding to the inter-board communication agent 131 is the same as the port number of the source port 235-1 corresponding to the inter-board communication agent 231, and the port number of the destination port 235-2 corresponding to the inter-board communication agent 231 is the same as the port number of the source port 135-2 corresponding to the inter-board communication agent 131;

[0144] The physical communication interface 102 is connected to the physical communication interface 202 .

[0145] like Figure 5 As shown, the communication method provided in the embodiment of the present application further includes the following steps S301 and S302 for implementing the first unidirectional intra-board communication (specifically, the third process unidirectionally sends data to the fourth process):

[0146] Step S301: Open the source port corresponding to the third process through the third process to obtain the third communication channel ID, and write the third data into the third shared space according to the third communication channel ID, and then enter step S302;

[0147] Step S302: Open the destination port corresponding to the fourth process through the fourth process to obtain the third communication channel ID, and read the third data from the third shared space according to the third communication channel ID.

[0148] In the application, the third process and the fourth process can be two different arbitrary processes running on the board, the third process sends the third data to the fourth process, and the fourth process receives the third data sent by the third process. According to the actual needs of the user, a group of virtual ports, including the source port corresponding to the third process and the destination port corresponding to the fourth process, are configured in advance at the USCI layer of the board through the intra-board communication agent, and then the intra-board communication agent establishes a globally unique third communication channel ID and a globally unique third shared space according to the port numbers of the group of virtual ports, and the third communication channel ID is stored in the third shared space.

[0149] In the application, the process of the third process sending the third data to the fourth process unidirectionally is as follows:

[0150] The third process opens the source port corresponding to the third process, reads the globally unique third communication channel ID from the third shared space, and writes the third data into the third shared space according to the third communication channel ID;

[0151] The fourth process opens the destination port of the fourth process, reads the globally unique third communication channel ID from the third shared space, and reads the third data from the third shared space according to the third communication channel ID, thereby enabling the third process to unidirectionally send the third data to the inter-board communication agent.

[0152] In one embodiment, before step S301, the following steps are included:

[0153] Through the intra-board communication agent, a globally unique third communication channel ID and a globally unique third shared space are established according to the port number of the source port corresponding to the third process and the port number of the destination port corresponding to the fourth process.

[0154] In the application, before the first intra-board communication is performed, the port number of the source port corresponding to the third process and the port number of the destination port corresponding to the fourth process are configured in advance through the intra-board communication agent according to the actual needs of the user, and then a globally unique third communication channel ID and a globally unique third shared space are established according to the port numbers of this group of virtual ports. The third communication channel ID is used to implement the mapping between the source port corresponding to the third process and the destination port corresponding to the fourth process, so that the third process can send the third data to the destination port corresponding to the mutually mapped fourth process after opening the corresponding source port.

[0155] like Figure 6 As shown, the communication method provided in the embodiment of the present application further includes the following steps S401 and S402 for implementing the second unidirectional intra-board communication (specifically, the fourth process unidirectionally sends data to the third process):

[0156] Step S401: Open the source port corresponding to the fourth process through the fourth process to obtain the fourth communication channel ID, and write the fourth data into the fourth shared space according to the fourth communication channel ID, and then enter step S402;

[0157] Step S402: Open the destination port corresponding to the third process through the third process to obtain a fourth communication channel ID, and read fourth data from the fourth shared space according to the fourth communication channel ID.

[0158] In the application, based on the same principle, the fourth process can also send fourth data to the third process, and the third process receives the fourth data sent by the fourth process. In advance, according to the actual needs of the user, a group of virtual ports, including the source port corresponding to the fourth process and the destination port corresponding to the third process, are configured at the USCI layer of the board through the intra-board communication agent. Then, the intra-board communication agent establishes a globally unique fourth communication channel ID and a globally unique fourth shared space according to the port numbers of the group of virtual ports, and the fourth communication channel ID is stored in the fourth shared space.

[0159] In the application, the process of the fourth process unidirectionally sending the fourth data to the third process is as follows:

[0160] The fourth process opens a source port corresponding to the fourth process, reads a globally unique fourth communication channel ID from the fourth shared space, and writes fourth data into the fourth shared space according to the fourth communication channel ID;

[0161] The third process opens the destination port of the third process, reads the globally unique fourth communication channel ID from the fourth shared space, and reads fourth data from the fourth shared space according to the fourth communication channel ID, thereby enabling the fourth process to unidirectionally send fourth data to the inter-board communication proxy.

[0162] In one embodiment, before step S401, the following steps are included:

[0163] Through the intra-board communication agent, a globally unique fourth communication channel ID and a globally unique fourth shared space are established according to the port number of the source port corresponding to the fourth process and the port number of the destination port corresponding to the third process.

[0164] In the application, before the second intra-board communication is performed, the port number of the source port corresponding to the fourth process and the port number of the destination port corresponding to the third process are configured in advance through the intra-board communication agent according to the actual needs of the user, and then a globally unique fourth communication channel ID and a globally unique fourth shared space are established according to the port numbers of this group of virtual ports. The fourth communication channel ID is used to implement the mapping between the source port corresponding to the fourth process and the destination port corresponding to the third process, so that the fourth process can send the fourth data to the destination port corresponding to the mutually mapped third process after opening the corresponding source port.

[0165] In application, based on the above steps of the first unidirectional intra-board communication and the second unidirectional intra-board communication, bidirectional communication between different processes in the board can be realized.

[0166] based on Figure 1 , Figure 7 An exemplary diagram of a two-way communication architecture between different processes in the same board is shown;

[0167] The source port 133-1 corresponding to the process 141 and the destination port 134-1 corresponding to the process 142 are mapped to each other, so as to realize unidirectional data transmission from the process 141 to the process 142;

[0168] The source port 134 - 2 corresponding to the process 142 and the destination port 133 - 2 corresponding to the process 141 are mapped to each other, so as to implement unidirectional data transmission from the process 142 to the process 141 .

[0169] In one embodiment, the third process or the fourth process and the first process may be the same process, and the same process in the board may communicate with other processes in the board and other processes outside the board.

[0170] In the application, within the same board, the data transmitted between the process and the inter-board communication agent, and between different processes can be messages. Users can control the communication system according to actual needs based on any human-computer interaction method supported by the energy storage valve control system, and configure the communication channel within the same board or between different boards through the intra-board communication agent and the inter-board communication agent.
