Description

Technical Field

[0001] This application relates to the field of communication protocol conversion technology, and in particular to a communication protocol conversion method and apparatus. Background Technology

[0002] With the development of technology, the interconnection between automated equipment is becoming increasingly important. The communication protocols between them are also diverse. Currently, no single protocol can properly adapt and connect all equipment produced by different manufacturers and at different times. Communication management units are used to solve the problem of communication protocol conversion between automated equipment.

[0003] Currently, communication management units are typically used to solve the problem of communication protocol conversion between automated devices. Existing invention CN201911315186.9 discloses a protocol conversion device and method on a communication management unit. An information acquisition module receives information uploaded by a lower-level device; a protocol identification module parses and analyzes the information to obtain its protocol type; a decapsulation module decapsulates the information acquired by the information acquisition module according to its protocol type; a packaging module packages the decapsulated information according to the protocol of the upper-level device; and an information uploading module uploads the packaged information to the upper-level device. This device can automatically identify the protocol type of the access device, thereby achieving secure and reliable protocol conversion by the communication management unit.

[0004] However, the method provided by this invention for identifying the protocol type of the lower-level machine is as follows: First, information of a first protocol type is sent to the lower-level machine. If the lower-level machine can recognize it and respond accordingly, the information received by the information acquisition module belongs to the first protocol type; otherwise, it does not belong to the first protocol type. The same method is used to sequentially verify whether it belongs to the second protocol type, the third protocol type, and so on, until the correct protocol type is found. Since there are many protocol types, multiple identification processes are generally required to identify the protocol type of the lower-level machine, resulting in low protocol conversion efficiency.

[0064] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0065] To facilitate understanding of the technical solution provided by this invention, the terminology of this invention will be explained below.

[0066] Communication management unit: Equipped with multiple downlink communication interfaces and one or more uplink network interfaces, it functions as a front-end unit or monitoring computer. It collects and aggregates communication data from all intelligent monitoring / protection devices within a substation and uploads it in real-time to the upper-level master station system (monitoring center backend unit and Distributed Control System (DCS)) to perform remote signaling and telemetry functions. On the other hand, it receives commands from the backend unit or DCS and forwards them to the intelligent series units within the substation, enabling remote control of the opening and closing of various switchgear or parameter setting of devices, thus achieving remote control and remote adjustment functions. It should also be equipped with multiple serial interfaces to facilitate communication with other intelligent devices within the substation. Communication management units are generally used in substations and dispatch stations. Through the control platform, the communication management unit controls the downlink Remote Terminal Unit (RTU) devices to collect remote signaling and telemetry information, feeding the messages back to the dispatch center. The control center administrator then processes and analyzes the messages to select the commands to execute, achieving the goal of remotely outputting dispatch commands.

[0067] Communication protocol, also known as communication procedure, refers to an agreement between communicating parties regarding the control of data transmission. This agreement includes standardized provisions for data format, synchronization methods, transmission speed, transmission steps, error detection and correction methods, and control character definitions. Both communicating parties must adhere to these provisions; it is also called a link control procedure. Common communication protocols include Modbus, BACnet, and the OPC specification protocol.

[0068] Point table: A term used in the automation control system industry. It describes the usage of various variables within an automation control system. In automation control, data points are simply called points, and the number of variables used in an automation control system is called the point count. Point tables serve as important bases and protocol standards for equipment providers, software providers, and system integrators. The entire construction of an automation control system is based on the descriptions and specifications of variables in the point tables. Typically, each variable has a corresponding unique variable name, device name, device address, register, register address, and other related information.

[0069] Polling is a method by which the CPU decides how to provide services to peripheral devices, also known as "Programmed I / O". The concept of polling is that the CPU periodically sends out queries to each peripheral device in sequence to see if it needs its service. If it does, it provides the service, and after the service is completed, it queries the next peripheral device, and so on, continuously.

[0070] Data point: A data item collected by the bottom-end device. Different data points represent different meanings, such as data points representing voltage or data points representing current. Each data point can have multiple attributes (e.g., name, ID, function code, etc.).

[0071] Bottom-level equipment: Used for monitoring and responding to the control of the main control equipment, such as monitoring voltage and current, and responding to the main control equipment's power-on and power-off commands.

[0072] Main control equipment; used to control the bottom-end equipment based on data monitored by the bottom-end equipment or user operations.

[0073] Telemetry (telemetry information): Remote measurement. Acquiring and transmitting operating parameters, including various electrical quantities (voltage, current, power, etc. on the line) and load flow.

[0074] Remote signaling (remote signaling information): Remote signals. Collects and transmits various protection and switching information.

[0075] Remote control (remote control information): Remote control. Receiving and executing remote control commands, primarily for opening and closing circuit breakers, and remotely controlling some switch control equipment.

[0076] Remote adjustment (remote adjustment information): Remote adjustment. Accepts and executes remote adjustment commands to remotely adjust controlled devices, such as adjusting generator output power.

[0077] The method provided in this embodiment of the invention is applied to a communication management machine. The communication management machine can also be called an internetwork connector or a protocol converter.

[0078] Example 1

[0079] This invention provides a communication protocol conversion method, such as... Figure 1 As shown, the method may include the following steps:

[0080] S110, the first protocol process is run to poll the data points in the first protocol point table.

[0081] The first protocol process is a process that handles the communication needs of at least one bottom device that adopts the first communication protocol. It can send commands to the bottom device, receive data sent by the bottom device, etc. It is configured with a corresponding protocol point table for each bottom device, and the protocol point table includes the first protocol point table corresponding to any one of the bottom devices.

[0082] When the first protocol process is running, the first protocol process polls the data points in the first protocol point table corresponding to each first bottom device.

[0083] The first data point is any data point in the first protocol point table, and each first data point represents a data item monitored by the first bottom-end device.

[0084] The first protocol point table includes the first feature data of the first data point, and the first feature data may include the acquisition path. The acquisition path indicates the source of the variable values ​​acquired by the communication management unit.

[0085] The first characteristic data represents the attribute of the first data point in the first protocol point table, and may include one or more of the following: table ID, variable name, acquisition path, data point type, and data point identifier. When receiving control commands from the master control device, the acquisition path may also be referred to as the target path, which will be explained in detail below.

[0086] In one example, the first protocol point table corresponding to the first bottom device is shown in Table 1.

[0087] Table 1 First Agreement Point Table

[0088]

[0089]

[0090] As shown in Table 1, the first protocol point table includes 6 data points. When the first data point is polled, its first characteristic data includes: table ID is 1, variable name is voltage, acquisition path is P2 / D1 / I1, data point type is telemetry, and data point identifier is 1. This indicates that the data point has a table ID of 1 in the first protocol point table; it acquires voltage data; the acquisition path is P2 / D1 / I1, where P2 represents the identifier of the first protocol process, D1 represents the device ID of the first bottom-end device is 1, and I1 represents the table ID of 1, indicating that the data source of this data point is the point with ID 1 in the first bottom-end device with ID 1 under the process of process number P2; the data point type indicates the behavior pattern of the data, and the data point identifier is used to distinguish the data. The meanings of the characteristic data of other data points in the table are similar.

[0091] S120, based on the first feature data and the first communication protocol corresponding to the first protocol process, a data acquisition command is sent to the first bottom device corresponding to the first protocol point table.

[0092] Based on the first feature data of the first data point and the first communication protocol corresponding to the first protocol process, a data acquisition command conforming to the first communication protocol is generated and then sent to the first bottom-end device corresponding to the first protocol point table. This data acquisition command is used to instruct the first bottom-end device to upload data.

[0093] Then, continue polling other data points in the first protocol point table until all rows in the first protocol point table have been traversed, and then start polling another protocol point table in the first protocol process.

[0094] S130, receive and store the variable values ​​corresponding to the acquisition path returned by the first bottom device in response to the acquisition command.

[0095] The first bottom-end device responds to the acquisition command and returns the variable value corresponding to the acquisition path. The communication management unit receives the variable value and uses the acquisition path as the data identifier of the variable value, and stores the variable value in the database.

[0096] In one example, the acquisition command indicates that the acquisition path of the first bottom device is P2 / D1 / I1. The variable monitored by the point with ID 1 in the first bottom device is voltage, and the first bottom device returns the voltage value to the communication management unit.

[0097] S140, the second protocol process is running to poll the data points in the second protocol point table.

[0098] The second protocol point table includes the second feature data of the second data point, and the second feature data includes the acquisition path.

[0099] The second protocol process is a process that handles the communication needs of at least one master control device that adopts the second communication protocol. It can receive commands sent by the master control device for controlling the bottom device, send data to the master control device, etc. It is configured with a corresponding protocol point table for each master control device, and the protocol point table includes the second protocol point table corresponding to any one of the first master control devices.

[0100] Moreover, the first communication protocol is different from the second communication protocol.

[0101] When the second protocol process is running, the second protocol process polls the data points in the corresponding second protocol point table of each first master control device once.

[0102] The second data point is a data point in the second protocol point table, and each second data point represents a data item controlled by the first master control device.

[0103] The second feature data represents the attribute of the second data point in the second protocol point table, and may include one or more of the following: table ID, variable name, acquisition path, data point type, and data point identifier.

[0104] Second protocol point table of a certain first master control device

[0105] In one embodiment, the second feature data of the second data point may include one or more of the following: table ID, variable name, acquisition path, data point type, and data point identifier.

[0106] In one example, the table of second protocol points corresponding to the first master control device is shown in Table 2.

[0107] Table 2 Second Agreement Points Table

[0108] ID in table variable name Collection path Data point type Data point identifier 1 #1 Voltage P2 / D1 / I1 telemetry 100 2 #2 Voltage P2 / D2 / I1 telemetry 101 3 #3 Power-on status P2 / D3 / I3 remote message 102

[0109] As shown in Table 2, the second protocol point table includes three data points. When the first data point is polled, its second characteristic data includes: table ID 1, variable name #1 voltage, acquisition path P2 / D1 / I1, data point type telemetry, and data point identifier 100. This indicates that the data point has a table ID of 1 in the first protocol point table; voltage data is extracted; the acquisition path is P2 / D1 / I1, where P2 represents the process number of the first protocol process, D1 represents the device ID of the first bottom-end device (ID 1), and I1 represents the table ID 1, indicating that the data source of this data point is the point with ID 1 in the first bottom-end device with ID 1 under the process of process number P2; the data point type indicates the behavior pattern of the data, and the data point identifier is used to distinguish the data. The meanings of the characteristic data of other data points in the table are similar.

[0110] S150, based on the second feature data and the second communication protocol corresponding to the second protocol process, sends the variable values ​​corresponding to the acquisition path to the first master control device corresponding to the second protocol point table.

[0111] Based on the acquisition path in the second feature data of the second data point, the variable value of the acquisition path identifier of the second data point is extracted from the database. A data frame conforming to the second communication protocol is generated based on the second communication protocol, the second feature data, and the variable value. The data frame includes the variable value. Then, the data frame is sent to the first master control device corresponding to the second protocol point table. After receiving the data frame, the first master control device completes the upload of the data from the first bottom-end device using the first communication protocol to the second master control device using the second communication protocol.

[0112] Then, continue polling the second protocol point table. If the upload path of a row that is polled is "NULL", skip that row.

[0113] The communication protocol conversion method provided in this embodiment of the invention uploads data from the bottom device to the master control device that uses a different communication protocol than the bottom device by configuring a point table. This realizes the communication protocol conversion between devices, which can improve the protocol conversion efficiency. Moreover, configuring the point table in the communication management machine is very simple and easy to implement, which can effectively improve the applicability of the communication management machine.

[0114] Example 2

[0115] In some embodiments, the first feature data further includes a first data point type and a first data point identifier, and the acquisition path includes a first bottom-end device ID of the first bottom-end device. Step S120: Based on the first feature data and the first communication protocol corresponding to the first protocol process, a acquisition command is sent to the first bottom-end device corresponding to the first protocol point table, which may include the following steps:

[0116] S121, if the first data point type belongs to the first target data point type, then extract the first data point identifier and the first bottom device ID of the first data point from the first protocol point table.

[0117] The first target data point types include telemetry and remote signaling.

[0118] Determine whether the first data point type is telemetry or tele-signaling. If it is telemetry or tele-signaling, extract the first data point identifier and the first bottom device ID from the first protocol point table.

[0119] In one example, the first protocol point table is shown in Table 1. The first data point is the second data point in the point table. The data type of this data point is telemetry. Then, the first data point identifier of the first data point extracted from the first protocol point table is 2, and the first bottom device ID is 1.

[0120] S122, query the topology table of the first protocol process for the port ID and the communication address of the first bottom device corresponding to the first bottom device ID.

[0121] The first protocol process contains a topology table, which describes the correspondence between the first protocol process and the tables of ports, devices, and points. Querying the topology table of the first protocol process yields the port ID and communication address of the first bottom-end device corresponding to its ID.

[0122] The communication management unit is equipped with at least one port, through which the first protocol process communicates with the bottom device.

[0123] In one example, the topology table for the first protocol process is shown in Table 3.

[0124] Table 3 Topology of the First Protocol Process

[0125]

[0126] The correspondence between the first bottom-end device ID, port ID, and communication address of the first bottom-end device is shown in Table 3. The first communication protocol is Protocol Q. The communication management unit communicates with the first bottom-end devices named Device 1 and Device 2 through port ID 1 in the topology table, and with the first bottom-end device named Device 3 through port ID 2.

[0127] S123, based on the first communication protocol, uses the port ID, the first bottom device communication address and the first data point identifier to generate a data acquisition command.

[0128] Based on the first communication protocol, the port ID, the first bottom device communication address, and the first data point identifier are combined to generate a data acquisition command that conforms to the first communication protocol.

[0129] S124, send a data acquisition command to the first bottom device.

[0130] The acquisition command is sent to the first bottom-end device through the port indicated by the port ID.

[0131] The method provided in this embodiment of the invention generates a collection command that conforms to the first communication protocol by configuring a first protocol point table on the communication management machine and generating the first feature data of the first data point based on the first communication protocol. This allows communication with the first bottom-end device using the first communication protocol to complete the issuance of the collection command. This improves protocol conversion efficiency, is easy to implement, and effectively enhances the applicability of the communication management machine.

[0132] Example 3

[0133] In some embodiments, step S130: receiving and storing the variable value corresponding to the acquisition path returned by the first bottom device in response to the acquisition command may include the following steps:

[0134] S131, Receive data returned by the first bottom device in response to the acquisition command.

[0135] The first bottom-end device responds to the acquisition command and returns data to the communication management unit, which then receives the data.

[0136] S132, parse the data to obtain the first data point type, port ID, first bottom device ID, and the first data point identifier and variable value of the first data point.

[0137] The first protocol process of the communication management machine parses the data returned by the first bottom device to the communication management machine, and obtains the first data point type, port ID, first bottom device ID, and the first data point identifier and variable value of the first data point.

[0138] S133, query the identifier of the first protocol point table corresponding to the port ID and the first bottom device ID in the topology table of the first protocol process.

[0139] By searching the topology table of the first protocol process, the identifiers of the first protocol point table corresponding to the aforementioned port ID and first bottom device ID are matched.

[0140] In one example, the topology table of the first protocol process is shown in Table 3. If the port ID is 1 and the first bottom device ID is 1, then the corresponding identifier of the first protocol point table is the protocol Q device 1 point table.

[0141] S134, if the first data point type belongs to the first target data point type, determine the acquisition path corresponding to the first data point type and the first data point identifier in the first protocol point table.

[0142] The first target data point types include telemetry and remote signaling.

[0143] Determine whether the first data point type is telemetry or teleindication. If it is telemetry or teleindication, query the first protocol point table for the corresponding acquisition path that matches the first data point type and the first data point identifier.

[0144] In one example, the first data point type is telemetry, the first data point identifier is 1, and the identifier of the first protocol point table is Protocol Q Device 1 Point Table, as shown in Table 1. From Table 1, the acquisition path corresponding to the first data point type and the first data point identifier being 1 is P2 / D1 / I1.

[0145] S134, stores variable values ​​based on the acquisition path.

[0146] The data identifier, which is used as a variable value, is stored in the database.

[0147] In one embodiment, the collection path and variable value are stored in the database as key name and key value, respectively.

[0148] In one embodiment, the database is a non-relational database used to store remote signaling and telemetry.

[0149] In one example, the database used to store telemetry data is shown in Table 4.

[0150] Table 4 Database

[0151]

[0152]

[0153] The method provided in this embodiment of the invention uses the acquisition path as the identifier of the variable value and stores the variable value in a non-relational database. It is fast, and the non-relational database is easy to expand, good at handling multiple processes and multiple concurrency, and has very high stability.

[0154] Example 4

[0155] In some embodiments, the second feature data further includes the second data point type, the second data point identifier, and the upload path of the second data point, wherein the upload path includes the first master control device ID of the first master control device. Step S150: Based on the second feature data and the second communication protocol corresponding to the second protocol process, send the variable value corresponding to the acquisition path to the first master control device corresponding to the second protocol point table, which may include the following steps:

[0156] S151, if the second data point type belongs to the first target data point type, then extract the second data point identifier and the first master control device ID of the second data point.

[0157] The primary target data point types include telemetry and telecontrol. The upload path indicates the location to which the communication management unit sends the variable values.

[0158] Determine whether the second data point type is telemetry or telesignaling. If it is telemetry or telesignaling, extract the second data point identifier from the second protocol point table and extract the first master control device ID from the upload path.

[0159] In one example, the table of second protocol points corresponding to the first master control device is shown in Table 5.

[0160] Table 5 Second Agreement Points Table

[0161]

[0162] When polling the first row of data points in Table 5, if the data point type is telemetry, then extract the second data point identifier of the second data point: 100, and extract the first master control device ID: 1 from the upload path P1 / D1 / I1.

[0163] S152, extract the variable values ​​corresponding to the acquisition path.

[0164] Extract variable values ​​from the database that are identified by the acquisition path of the second data point.

[0165] In one example, if the second data point is the first data point in Table 5, then the variable value identified by the collection path P2 / D1 / I1 is extracted.

[0166] S153, query the topology table of the second protocol process for the first port ID and the first master control device communication address corresponding to the first master control device ID.

[0167] The second protocol process contains a topology table, which describes the correspondence between the second protocol process and the tables of ports, devices, and points. Querying the topology table of the second protocol process yields the first port ID and the first master control device communication address corresponding to the first master control device ID.

[0168] The communication management unit is equipped with at least one port, through which the second protocol process communicates with the bottom device.

[0169] In one example, the topology table for the second protocol process is shown in Table 6.

[0170] Table 6 Topology of the Second Protocol Process

[0171]

[0172] The correspondence between the first master control device ID, port ID, and communication address is shown in the first row of data points in Table 6. The second communication protocol is Protocol A, and the communication management unit communicates with the first master control device named Device 1 through the port with port ID 1 in the topology table.

[0173] S154, based on the second communication protocol, sends variable values ​​to the first master control device according to the second data point identifier, the first port ID, and the first master control device communication address.

[0174] Based on the second communication protocol, the first port ID, the second data point identifier, the first port ID, the first master control device communication address, and the variable value are combined to obtain a data frame, and the data frame is sent to the first master control device communication address of the first master control device through the port represented by the first port ID.

[0175] The method provided in this embodiment of the invention generates a data frame that conforms to the second communication protocol by configuring a second protocol point table on the communication management machine and generating the second feature data of the second communication protocol and the second data point. The data frame can then be sent to the first bottom-end device using the first communication protocol to complete the data upload. This method can improve the protocol conversion efficiency, is easy to implement, and effectively improve the applicability of the communication management machine.

[0176] Example 5

[0177] In some embodiments, such as Figure 2 As shown, the method provided in this embodiment of the invention may further include the following steps:

[0178] S160 runs the third protocol process, and based on the corresponding third communication protocol of the third protocol process, receives and parses the control commands of the second master control device to obtain the command value and the third characteristic data of the third data point.

[0179] The third protocol process is a protocol process that handles the communication needs of the master control device that uses the third communication protocol. It can receive control commands from the master control device, etc. It contains a protocol point table for each master control device, and the protocol point table includes the third protocol point table for any second master control device.

[0180] The third protocol process can be the same as or different from the second communication protocol.

[0181] The third protocol process is run. After receiving the control command from the second master control device, the third protocol process parses the control command based on the corresponding third communication protocol to obtain the command value and the third feature data of the third data point.

[0182] The third feature data represents the attributes of the third data point in the third protocol point table, and may include one or more of the following: table ID, variable name, acquisition path, upload path, target path, data point type, and data point identifier.

[0183] S170, query the third protocol point table of the third protocol process for the target path corresponding to the third feature data.

[0184] The target path is the control target of the second master control device.

[0185] In one example, the target path corresponding to the third feature data is P2 / D1 / I4, which means that the control target of the second master control device is the bottom device with device ID 1 corresponding to protocol process P2, and the variable represented by the data point with ID 4 in the corresponding protocol point table.

[0186] S180 runs the fourth protocol process, receiving command values ​​and target paths sent by the third protocol process.

[0187] The fourth protocol process is a protocol process that handles the communication needs of the master control device that uses the fourth communication protocol. It can receive command values ​​and target paths sent by the third protocol process, and send control commands to the bottom devices that use the fourth communication protocol. It is configured with a corresponding protocol point table for each bottom device, and the protocol point table includes the fourth protocol point table corresponding to any second bottom device.

[0188] The fourth communication protocol process differs from the third communication protocol. When the third communication protocol differs from the first communication protocol, the fourth communication protocol can be the same as the first communication protocol.

[0189] The fourth protocol process is running, and it receives command values ​​from the target path and the second master control device.

[0190] S190, query the fourth protocol point table of the fourth protocol process for the fourth feature data corresponding to the target path.

[0191] The fourth protocol point table includes the correspondence between the target path and the fourth feature data. By querying the fourth protocol point table, the fourth feature data corresponding to the target path can be obtained.

[0192] The fourth feature data represents the attributes of the fourth data point in the fourth protocol point table, and may include one or more of the following: table ID, variable name, acquisition path / target path, data point type, and data point identifier.

[0193] S200, at least according to the fourth feature data and the fourth communication protocol corresponding to the fourth protocol process, sends a command value to the second bottom device corresponding to the fourth protocol point table.

[0194] The fourth feature data and command value are combined based on the fourth communication protocol to generate a data frame that conforms to the fourth communication protocol. The data includes the command value, and the data frame is sent to the second bottom device.

[0195] The communication protocol conversion method provided in this embodiment of the invention sends commands from the master control device to the bottom device that uses a different communication protocol than the master control device through communication management and configuration point table, thereby realizing communication protocol conversion, improving protocol conversion efficiency, and the configuration point table in the communication management machine is very simple and easy to implement, which can effectively improve the applicability of the communication management machine.

[0196] Example 6

[0197] In some embodiments, the third characteristic data may include the second master device ID, the second port ID, the third data point type, and the third data point identifier. Step S170: Querying the third protocol point table of the third protocol process for the target path corresponding to the third characteristic data may include the following steps:

[0198] S171, query the topology table of the third protocol process, and find the identifier of the third protocol point table corresponding to the second master control device ID and the second port ID.

[0199] The third protocol process contains a topology table, which describes the correspondence between the third protocol process and ports, devices, and point tables. Querying the third protocol process's topology table yields the identifiers of the third protocol point tables corresponding to the second master control device ID and the second port ID.

[0200] In one example, the third communication protocol is the same as the second communication protocol, and the first master control device is the same as the second master control device. The topology table of the third protocol process is shown in Table 6. The correspondence between the second master control device ID and the second port ID and the identifiers in the third protocol point table is shown in the first row of data points in Table 6. The third communication protocol is Protocol A, and the communication management machine communicates with the second master control device named Device 1 through the port with port ID 1 in the topology table.

[0201] S172, If the third data point type belongs to the second target data point type, extract the target path corresponding to the third data point type and the third data point identifier in the third protocol point table represented by the identifier of the third protocol point table.

[0202] The second target data point type includes remote adjustment and remote control. The third protocol point table includes the correspondence between the third data point type, the third data point identifier, and the target path.

[0203] Determine whether the second data point type is telemetry or teleindication. If it is telemetry or teleindication, extract the target path corresponding to the third data point type and the third data point identifier from the third protocol point table.

[0204] In one example, the third communication protocol is the same as the second communication protocol, and the first master control device is the same as the second master control device. The third protocol point table is shown in Table 7.

[0205] Table 7 Third Agreement Point Table

[0206]

[0207] If the third data point type is remote adjustment and the third data point identifier is 103, then the corresponding target path is P2 / D1 / I4, indicating that the control target of the second master control device is the bottom device with device ID 1 corresponding to the protocol process identified as P2, and the given voltage represented by the data point with ID 4 in the corresponding protocol point table.

[0208] The method provided in this embodiment of the invention configures a protocol point table and a topology table on the communication management machine, searches the protocol point table and topology table of the corresponding third protocol process of the third communication protocol, and obtains the target path, thus providing a target for issuing control commands.

Step S190: Querying the fourth protocol point table of the fourth protocol process for the fourth feature data corresponding to the target path may include the following steps:

[0211] S191, extract the second bottom device ID and the ID in the table from the target path.

[0212] S192, query the topology table of the fourth protocol process for the third port ID, the communication address of the second bottom device, and the identifier of the fourth protocol point table corresponding to the second bottom device ID.

[0213] The fourth protocol process contains a topology table, which describes the correspondence between the fourth protocol process and ports, devices, and point tables. Querying the fourth protocol process's topology table yields the third port ID corresponding to the second bottom-end device ID, the communication address of the second bottom-end device, and the identifier of the fourth protocol point table.

[0214] In one example, the fourth protocol process is the same as the first protocol process. The topology table of the fourth protocol process is shown in Table 3. If the second bottom device ID of the target path is 1, then the corresponding third port ID is 1, the second bottom device communication address is 3000, and the identifier of the fourth protocol point table is Protocol Q Device 1 point table.

[0215] S193, query the fourth feature data corresponding to the ID in the fourth protocol point table represented by the identifier of the fourth protocol point table.

[0216] The fourth protocol point table includes the correspondence between the IDs in the table and the fourth feature data.

[0217] In one embodiment, the fourth feature data may include the fourth data point type and the fourth data point identifier.

[0218] In one example, the fourth communication protocol is the same as the first communication protocol. The identifier of the fourth protocol point table is shown in Table 1. If the ID in the table is 4, then the corresponding fourth data point type is remote adjustment and the fourth data point identifier is 4.

[0219] The method provided in this embodiment of the invention configures a protocol point table and a topology table in the communication management machine, searches the protocol point table and topology table of the fourth protocol process corresponding to the fourth communication protocol, and obtains the fourth feature data, providing the necessary data for the issuance of control commands.

[0220] Example 8

[0221] In some embodiments, the fourth feature data includes the fourth data point type and the fourth data point identifier. Step S200: Sending a command value to the second bottom-end device corresponding to the fourth protocol point table, at least according to the second feature data and the fourth communication protocol corresponding to the fourth protocol process, may include the following steps:

[0222] S201, according to the fourth communication protocol corresponding to the fourth protocol process, generate the target control command by combining the fourth data point type, the fourth data point identifier, the third port ID, the second bottom device communication address and the command value.

[0223] Based on the fourth communication protocol, the fourth data point type, the fourth data point identifier, the third port ID, the second bottom device communication address, and the command value are combined to obtain the target control command.

[0224] S202, send the target control command to the second bottom device corresponding to the fourth protocol point table.

[0225] The target control command is sent to the second bottom device through the port represented by the third port ID.

[0226] The method provided in this embodiment of the invention obtains the target control command by combining the fourth data point type, the fourth data point identifier, the third port ID, the second bottom device communication address, and the command value, and sends the target control command to the second bottom device to complete the issuance of the control command, thereby improving the protocol conversion efficiency.
