Technical Field

[0002] The present application relates to the field of communications, and in particular provides a communication method, a board, an energy storage valve control system, and a storage medium. Background Art

[0003] Energy storage valve control systems typically utilize a multi-board design (e.g., control board, interface board, input / output board, display panel, etc.), each of which may have different functions or architectures. The application software configured on these boards can run based on an operating system or directly on a processor. The physical communication interface between the boards can be a point-to-point bus interface or a shared bus interface, such as Ethernet, RS485, Controller Area Network (CAN), or Low-Voltage Differential Signaling (LVDS).

[0004] 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.

[0005] Application Contents

[0006] The purpose of this application is to provide a communication method, board, energy storage valve control system and storage medium, aiming to solve the problem that the current communication method between boards is usually based on the physical signal interface driven by the same operating system, with poor portability, scalability and flexibility.

[0007] 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. The communication system includes a driver layer, an operating system layer, and an application layer, and also includes a unified system communication interface layer established between the operating system layer and the application layer. The communication method includes:

[0008] Opening, through the first process, a source port corresponding to the first process to obtain a first communication channel identifier, and writing the first data into the first shared space according to the first communication channel identifier;

[0009] Opening a destination port corresponding to the inter-board communication agent through the inter-board communication agent to obtain a first communication channel identifier, and reading first data from the first shared space according to the first communication channel identifier;

[0010] Writing the port number of the destination port corresponding to the inter-board communication agent into the first data through the inter-board communication agent to generate first target data;

[0011] Sending the first target data to the driver layer through the inter-board communication agent;

[0012] driving at least one physical communication interface of the board card to send the first target data to the physical communication interface of at least one other board card through the driver layer;

[0013] The unified system communication interface layer includes an inter-board communication agent, a destination port corresponding to the inter-board communication agent, and a source port corresponding to the first process.

[0014] On the first aspect, a communication method is provided based on a communication system running on a board, 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, there is no need to know the address of the data recipient, only Based on the mapping relationship between each group of virtual ports, communication between different boards can be achieved, and there is no restriction on the types of operating systems running on different boards. This inter-board communication method is transparent to the user (user transparency means that the user does not need to care about the specific communication implementation method. It is transparent and invisible to the user and the user only needs to use it). Based on this, by pre-establishing the mapping between different virtual ports, the data sender (i.e., the first process) and the data receiver (i.e., at least one other board) can be flexibly bound, thereby enabling different data routing. It can be applied to any board and has good portability, scalability, and flexibility. The first aspect specifically enables a board to send data unidirectionally to at least one other board, that is, one send and one receive or one send and multiple receive.

[0015] In a first implementation of the first aspect, opening, by a first process, a source port corresponding to the first process to obtain a first communication channel identifier, and before writing the first data to the first shared space according to the first communication channel identifier, includes:

[0016] Through the inter-board communication agent, a globally unique first communication channel identifier 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.

[0017] The first implementation method of the first aspect is to establish a globally unique first communication channel identifier and a globally unique first shared space based on the inter-board communication agent according to the actual needs of the user before inter-board communication, according to the port number of the source port corresponding to the first process configured by the user and the port number of the destination port corresponding to the inter-board communication agent, so that based on the first communication channel identifier, the mapping between the source port corresponding to the first process and the destination port corresponding to the inter-board communication agent is realized, and based on the first communication channel identifier and the first shared space, the first process writes data and the inter-board communication agent reads data, thereby realizing communication between the first process and the inter-board communication agent, and then realizing communication between the first process and the inter-board communication agent, and further realizing communication between the first process and other boards, with good scalability and flexibility.

[0018] Based on the first or second implementation of the first aspect, in the second implementation of the first aspect, the number of destination ports corresponding to the inter-board communication agent is multiple, and each destination port corresponding to the inter-board communication agent is mapped to a source port corresponding to the first process;

[0019] The communication method also includes:

[0020] 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.

[0021] A second implementation of the first aspect, when there are multiple destination ports corresponding to the inter-board communication agent, based on a pre-established mapping relationship between each destination port corresponding to the inter-board communication agent and a source port corresponding to a first process, enables the inter-board communication agent to generate multiple first target data based on the first data sent by the multiple first processes, and package and send them to the driver layer for transmission to other boards via the driver layer, thereby enabling unidirectional batch data communication between different boards. The second implementation of the first aspect can specifically enable unidirectional batch data transmission from a board to at least one other board.

[0022] Based on the first aspect, or the first or second implementation of the first aspect, in a third implementation of the first aspect, the communication method further includes:

[0025] Opening 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 agent through the inter-board communication agent to obtain the second communication channel identifier, and writing the second data into the second shared space according to the second communication channel identifier;

[0026] Opening, by the second process, a destination port corresponding to the second process to obtain a second communication channel identifier, and reading second data from the second shared space according to the second communication channel identifier;

[0027] The unified system communication interface layer further includes a source port corresponding to the inter-board communication agent and a destination port corresponding to the second process.

[0028] The third implementation of the first aspect is based on a pre-established mapping relationship between each group of virtual ports of the board, by making the port number of the source port corresponding to the inter-board communication agent of the board the same as the port number of the destination port corresponding to other inter-board communication agents of other boards, a mapping relationship between the virtual ports of different boards can be established. This allows the user to achieve inter-board communication based on the mapping relationship between the virtual ports of different boards without knowing the address of the data receiver, without having to know the address of the data receiver. There is no restriction on the type of operating system running on different boards. This inter-board communication method is transparent to the user. Based on this, by pre-establishing the mapping between the virtual ports of different boards, the data sender (i.e., the other board) and the data receiver (i.e., the second process) can be flexibly bound, thereby enabling different data routing. It can be applied to any board and has good portability, scalability and flexibility. The third implementation of the first aspect, based on the first aspect, can further achieve a board receiving data sent by at least one other board in a unidirectional manner, i.e., one send and one receive or multiple send and one receive, thereby achieving bidirectional data communication between different boards as a whole.

[0029] Based on the third implementation of the first aspect, in a fourth implementation of the first aspect, before the physical communication interface of the driving board receives, through the driver layer, the second target data sent by the physical communication interface of the other board, the method includes:

[0030] Through the inter-board communication agent, a globally unique second communication channel identifier 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.

[0031] The fourth implementation method of the first aspect is to establish a common and globally unique second communication channel identifier and a common and globally unique second shared space based on the inter-board communication agent according to the actual needs of the user before inter-board communication, according to the port number of the source port corresponding to the inter-board communication agent configured by the user and the port number of the destination port corresponding to the second process, so that based on the second communication channel identifier, the mapping between the source port corresponding to the inter-board communication agent and the destination port corresponding to the second process is realized, and based on the second communication channel identifier and the second shared space, the inter-board communication agent writes data and the second process reads data, thereby realizing communication between the inter-board communication agent and the second process, and then realizing communication between the second process and other boards, with good scalability and flexibility.

[0033] The communication method also includes:

[0034] When multiple packaged second target data are obtained through the inter-board communication agent, the inter-board communication agent is used to unpack and parse all the second target data to obtain the port numbers of multiple source ports corresponding to the inter-board communication agent and multiple second data.

[0035] The fifth implementation method of the first aspect is that, when there are multiple source ports corresponding to the inter-board communication agent, based on the pre-established mutual mapping relationship between each source port corresponding to the inter-board communication agent and the destination port corresponding to a second process, the inter-board communication agent can, when receiving multiple packaged second target data sent by at least one other board, unpack the package to obtain the port numbers of the multiple destination ports corresponding to the other inter-board communication agents and multiple second data, and then distribute the multiple second data to each second process 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, thereby realizing unidirectional batch data communication between different boards. The fifth implementation method of the first aspect can specifically realize the unidirectional reception of batch data sent by at least one other board by the board.

[0036] Based on the third or fourth implementation of the first aspect, in a sixth implementation of the first aspect, the second process and the first process are the same process.

[0037] A sixth implementation of the first aspect, when the second process and the first process are the same process, can implement bidirectional communication between the same process within the board and the inter-board communication agent.

[0038] Based on the first aspect, or any one of the first to sixth implementations of the first aspect, in a seventh implementation of the first aspect, the communication method further includes:

[0039] Opening, by the third process, a source port corresponding to the third process to obtain a third communication channel identifier, and writing the third data into the third shared space according to the third communication channel identifier;

[0041] The unified system communication interface layer further includes a source port corresponding to the third process and a destination port corresponding to the fourth process.

[0042] The seventh implementation method of the first aspect is based on the pre-established mapping relationship between each group of virtual ports, so that when intra-board communication is required and the user does not know the address of the data recipient, the user does not need to know the address of the data recipient to achieve communication between different processes in the same board card. This intra-board communication method is transparent to the user. Based on this, by pre-establishing the mapping between different virtual ports, the data sender (that is, the third process) and the data receiver (that is, the fourth process) can be flexibly bound, so that different data routing can be performed. It can be applied to any board card and has good portability, scalability and flexibility.

[0043] Based on the seventh implementation of the first aspect, in the eighth implementation of the first aspect, the unified system communication interface layer further includes an intra-board communication agent;

[0044] Opening a source port corresponding to the third process by the third process to obtain a third communication channel identifier, and before writing the third data into the third shared space according to the third communication channel identifier, includes:

[0045] Through the intra-board communication agent, a globally unique third communication channel identifier 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.

[0046] The eighth implementation method of the first aspect is to establish a common and globally unique third communication channel identifier and a common and globally unique third shared space before conducting intra-board communication based on the intra-board communication agent according to the actual needs of the user, 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 configured by the user, so that based on the third communication channel identifier, the mapping between the source port corresponding to the third process and the destination port corresponding to the fourth process is realized, and based on the third communication channel identifier and the third shared space, the third process writes data and the fourth process reads data, thereby realizing communication between the third process and the fourth process, that is, realizing communication between different processes within the board, with good scalability and flexibility.

[0047] Based on the seventh or eighth implementation manner of the first aspect, in a ninth implementation manner of the first aspect, the third process and the first process are the same process.

[0048] An eighth implementation of the first aspect, when the third process and the first process are the same process, can enable the same process within the board to communicate with other processes within the board and other processes outside the board respectively.

A common communication channel identifier (Identity) is established based on each group of source ports and destination ports. Document, ID) and shared space are used to establish a mapping relationship between each group of virtual ports (i.e., source port and virtual port). This makes it possible to establish a mapping relationship between each group of virtual ports (i.e., source port and virtual port) when intra-board communication or inter-board communication is required and the user does not know the address of the data receiver, without having to know the address of the data receiver. Only based on the mapping relationship between each group of virtual ports, communication between different processes within the board or between different boards can be achieved. There is no restriction on the types of operating systems running on different boards. This communication method is transparent to the user. Based on this, by pre-establishing mappings between different virtual ports, the data sender and the data receiver can be flexibly bound, thereby enabling different data routing. This method can be applied to any board, has good portability, scalability, and flexibility, can effectively shorten the R&D cycle, and is easy to maintain and test.

[0101] According to the port number of each group of virtual ports, a globally unique communication channel ID and a globally unique shared space corresponding to each group of virtual ports are established, and the communication channel ID is stored in the shared space;

[0102] The intra-board and inter-board communication agents are also used to:

[0103] Configure the communication channel within the same board or between different boards. The specific configuration content includes but is not limited to: source port, destination port, port number of the source port, port number of the destination port, communication channel ID, port type, data size, channel depth, driver type, etc.

[0104] In application, the communication method provided in the embodiment of the present application can be applied to different boards of the energy storage valve control system (including the above-mentioned boards and at least one other board), and the energy storage valve control system can be applied to flight equipment in the aviation / aerospace field, electric vehicles or car batteries in the automotive field, etc.

[0105] As shown in FIG2 , the communication method provided in an embodiment of the present application includes the following steps S101 to S105 for implementing a first type of unidirectional inter-board communication (specifically, a board sending data unidirectionally to at least one other board):

[0108] In an application, the first process can be any process running on a board that needs to send data to other processes running on other boards. Based on the user's actual needs, a set of virtual ports, consisting of a source port corresponding to the first process and a destination port corresponding to the inter-board communication agent, is configured in advance at the USCI layer of the board via the inter-board communication agent. The inter-board communication agent then establishes a globally unique first communication channel ID and a globally unique first shared space based on the port numbers of these virtual ports. The first communication channel ID is stored in the first shared space.

[0109] In the application, the process of the first process unidirectionally sending the first data to the inter-board communication agent is as follows:

[0110] The first process opens the source port corresponding to the first process, reads the globally unique first communication channel ID from the first shared space, and writes the first data into the first shared space according to the first communication channel ID;

[0111] The inter-board communication agent opens the destination port corresponding to the inter-board communication agent, reads the globally unique first communication channel ID from the first shared space, and reads the first data from the first shared space according to the first communication channel ID, thereby realizing the unidirectional sending of the first data by the first process to the inter-board communication agent.

[0112] Step S103: Write the port number of the destination port corresponding to the inter-board communication agent into the first data through the inter-board communication agent to generate first target data, and then proceed to step S104;

[0113] Step S104: Send the first target data to the driver layer through the inter-board communication agent, and proceed to step S105;

[0114] 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.

[0115] In the application, according to the actual needs of the user, 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, 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 the other boards receive the first target data carrying the port number of the destination port corresponding to the inter-board communication agent, they can open the source port corresponding to the other inter-board communication agent 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 port corresponding to the other inter-board communication agent and the destination ports corresponding to other processes running on the other boards.

[0116] In an application, the inter-board communication agent triggers the driver layer to drive at least one physical communication interface of a board to send first target data to the physical communication interface of at least one other board, implementing a one-transmit-one-receive or one-transmit-multiple-receive scenario. When implementing a one-transmit-multiple-receive scenario, each physical communication interface of a board sends the first target data to a physical communication interface on one other board.

[0117] In one embodiment, before step S101, the following steps are included:

[0118] 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.

[0119] In the application, before performing the first type of inter-board communication, 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 based on the port numbers of this group of virtual ports. The first communication channel ID is used to achieve 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, after opening the corresponding source port, send the first data to the destination port corresponding to the mutually mapped inter-board communication agent in a targeted manner. The specific implementation method is: the first process writes the first data to 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 communication between the first process and the inter-board communication agent, and then realizing communication between the first process and other boards, with good scalability and flexibility.

[0120] 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 the first process;

[0121] The above communication method further includes the following steps for implementing the second type of unidirectional inter-board communication (specifically, a board sending unidirectional batch data to at least one other board):

[0122] 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.

[0123] In an application, if the inter-board communication proxy corresponds to multiple destination ports, multiple first processes can simultaneously send data unidirectionally to the inter-board communication proxy via the corresponding source ports. The principle of each first process sending data unidirectionally to the inter-board communication proxy is the same as steps S101 to S103 and will not be repeated here. The inter-board communication proxy can generate multiple first target data corresponding 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 for transmission to other boards via the driver layer, thereby achieving unidirectional batch data communication between different boards.

[0124] As shown in FIG3 , the communication method provided in the embodiment of the present application further includes the following steps S201 to S204 for implementing a third type of unidirectional inter-board communication (specifically, a board unidirectionally receives data sent by at least one other board):

[0125] Step S201: The physical communication interface of the driving board receives second target data sent by the physical communication interface of at least one other board through the driving layer, and then proceeds to step S202.

[0126] In an application, the inter-board communication agent triggers the driver layer to drive at least one physical communication interface of a board to receive second target data sent by the physical communication interface of at least one other board, implementing a one-transmit-one-receive or multiple-transmit-one-receive scenario. When multiple-transmit-one-receive is implemented, each physical communication interface of the driver board receives the second target data sent by a physical communication interface on one other board.

[0127] Step S202: Obtain the second target data through the inter-board communication agent and parse it to obtain the port number of the source port corresponding to the other inter-board communication agent and the second data, and then proceed to step S203.

[0128] 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 port corresponding to the other inter-board communication agents, so that 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.

[0129] 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 then proceed to step S204;

[0130] 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.

[0131] In an application, the second process can be any process running on a board that needs to receive data sent by other processes running on other boards. Based on the user's actual needs, a virtual port pair consisting of a destination port corresponding to the second process and a source port corresponding to the inter-board communication agent is configured in advance at the USCI layer of the board via the inter-board communication agent. The inter-board communication agent then establishes a globally unique second communication channel ID and a globally unique second shared space based on the port numbers of these virtual ports. The second communication channel ID is stored in the second shared space.

[0132] In the application, the process of the inter-board communication agent unidirectionally sending the second data to the second process is as follows:

[0133] 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 agent, 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;

[0134] 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.

[0135] In one embodiment, before step S201, the following steps are included:

[0136] 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.

[0137] In the application, before performing the third type of inter-board communication, 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 based on the port numbers of this group of virtual ports. The second communication channel ID is used to achieve 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, after opening the corresponding source port, send the second data to the destination port corresponding to the first process that is mapped to each other. The specific implementation method is: the inter-board communication agent writes the second data to 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 communication between the inter-board communication agent and the second process, and then realizing communication between the second process and other boards, with good scalability and flexibility.

[0138] 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 the second process;

[0139] The above communication method further includes the following steps for implementing the fourth type of unidirectional inter-board communication (specifically, a board receiving data sent in batches unidirectionally by at least one other board):

[0140] When multiple packaged second target data are obtained through the inter-board communication agent, the inter-board communication agent is used to unpack and parse all the second target data to obtain the port numbers of multiple destination ports corresponding to other inter-board communication agents and multiple second data.

[0141] In an application, when there are multiple source ports corresponding to the inter-board communication agent, the inter-board communication agent can receive multiple packaged second target data sent by at least one other board, and then unpack them to obtain the port numbers and multiple second data of the multiple destination ports corresponding to the other inter-board communication agents. 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, and will not be repeated here.

[0142] In one embodiment, the second process and the first process can be the same process. Based on the above-mentioned steps of the first one-way inter-board communication and the fourth one-way inter-board communication, two-way communication between the same process in the board card and the inter-board communication agent can be realized, and then two-way communication between the same process of the board card and other boards can be realized.

[0143] In application, the board communicates with other boards based on the aforementioned communication method. When a board uses the communication method shown in FIG2 to unidirectionally send data to at least one other board, the other board can use the communication method shown in FIG3 to receive the data sent unidirectionally by the board. Similarly, when a board uses the communication method shown in FIG3 to receive data sent unidirectionally by at least one other board, the other board can use the communication method shown in FIG2 to unidirectionally send data to the board.

[0144] Based on FIG1 , FIG4 exemplarily shows a bidirectional communication architecture diagram between two different boards when the second process and the first process are the same process;

[0145] Wherein, the board 100 is the board in the embodiment corresponding to FIG1 ;

[0146] 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 implement unidirectional data transmission from the inter-board communication agent 231 to the process 242;

[0147] 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 implement unidirectional data transmission from the process 242 to the inter-board communication agent 231;

[0148] 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;

[0149] The physical communication interface 102 is connected to the physical communication interface 202 .

[0150] As shown in FIG5 , the communication method provided in the embodiment of the present application further includes the following steps S301 and S302 for implementing a first type of unidirectional intra-board communication (specifically, unidirectional data transmission from the third process to the fourth process):

[0151] 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 proceed to step S302;

[0152] 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.

[0153] In an application, the third process and the fourth process can be two different arbitrary processes running on the board. The third process sends third data to the fourth process, and the fourth process receives the third data sent by the third process. Based on the user's actual needs, a set of virtual ports, namely the source port corresponding to the third process and the destination port corresponding to the fourth process, is configured in advance at the USCI layer of the board via an intra-board communication agent. The intra-board communication agent then establishes a globally unique third communication channel ID and a globally unique third shared space based on the port numbers of these virtual ports. The third communication channel ID is stored in the third shared space.

[0154] In the application, the process of the third process sending the third data to the fourth process unidirectionally is as follows:

[0155] 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;

[0156] 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.

[0157] In one embodiment, before step S301, the following steps are included:

[0158] 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.

[0159] In the application, before the first type of 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. Then, based on the port numbers of this set of virtual ports, a globally unique third communication channel ID and a globally unique third shared space are established. The third communication channel ID is used to implement a mapping between the source port corresponding to the third process and the destination port corresponding to the fourth process, so that after the third process opens the corresponding source port, it can send third data to the mutually mapped destination port corresponding to the fourth process.

[0160] As shown in FIG6 , 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 sending data to the third process):

[0161] 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 proceed to step S402;

[0162] 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.

[0163] In applications, based on the same principle, the fourth process can also send fourth data to the third process, and the third process can receive the fourth data sent by the fourth process. Based on the user's actual needs, a virtual port pair consisting of a source port corresponding to the fourth process and a destination port corresponding to the third process is configured in advance at the USCI layer of the board through the intra-board communication agent. The intra-board communication agent then establishes a globally unique fourth communication channel ID and a globally unique fourth shared space based on the port numbers of these virtual ports. The fourth communication channel ID is stored in the fourth shared space.

[0164] In the application, the process of the fourth process sending the fourth data to the third process unidirectionally is as follows:

[0165] 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 the fourth data into the fourth shared space according to the fourth communication channel ID;

[0166] 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 the fourth data from the fourth shared space according to the fourth communication channel ID, thereby enabling the fourth process to unidirectionally send the fourth data to the inter-board communication agent.

[0167] In one embodiment, before step S401, the following steps are included:

[0168] 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.

[0169] In the application, before performing the second type of intra-board communication, 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. Then, based on the port numbers of this set of virtual ports, a globally unique fourth communication channel ID and a globally unique fourth shared space are established. The fourth communication channel ID is used to implement a mapping between the source port corresponding to the fourth process and the destination port corresponding to the third process. After the fourth process opens the corresponding source port, it can send fourth data to the mapped destination port corresponding to the third process.

[0170] 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 achieved.

[0171] Based on Figure 1, Figure 7 exemplarily shows a bidirectional communication architecture diagram between different processes in the same board;

[0172] 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 to implement unidirectional data transmission from the process 141 to the process 142.

[0173] 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 .

[0174] In one embodiment, the third process or the fourth process and the first process may be the same process, and the same process within the board may communicate with other processes within the board and other processes outside the board.

[0175] In applications, data transmitted between processes and inter-board communication agents, or between different processes within the same board, can be messages. Users can control the communication system based on actual needs, using any human-computer interaction method supported by the energy storage valve control system. Communication channels within the same board or between different boards can be configured through the intra-board and inter-board communication agents. Specific configuration details include, but are not limited to, source port, destination port number, source port number, destination port number, communication channel ID, port type, data size, channel depth, and driver type. The port type identifies whether each source and destination port is used for intra-board or inter-board communication. The channel depth defines how much data can be stored in each shared space. The driver type defines the type of physical communication interface.
