[0023] In the following description, specific details are set forth such as particular system configurations, techniques, etc., in order to provide a thorough understanding of the embodiments of the application. However, persons skilled in the art will understand that the application can be practiced without these specific details. In other instances, well-known structures, devices, circuits, and methods have not been described in detail in order to avoid obscuring the description of the application.

[0024] In order to make the objectives, technical solutions and advantages of the application clearer, the following will be described by specific embodiments in conjunction with the accompanying drawings.

[0025] Reference Figure 1 The embodiment provides a communication connection schematic diagram of a monitoring host commonly used in the prior art, as shown in Figure 1 The monitoring host is in communication connection with a plurality of collection terminals (1, 2... n) in the south direction. Since the communication protocols of different collection terminals and the monitoring host can be different, when the southward communication protocol of the monitoring host is tested, a common technical means is to design a communication protocol test tool for each communication protocol, use the communication protocol test tool to simulate the communication process with the monitoring host, so as to test the communication protocol of the monitoring host and the collection terminal. However, with the continuous strengthening of the function of the monitoring system, the southward protocol of the monitoring host is more and more, and the test tool needed is more and more, and too many test tools are used at the same time, which will cause the problem of flashing due to too much resource occupation.

[0026] Based on the above problems, the embodiment provides a multi-communication protocol test method, as shown in Figure 2Fig. 1 shows a flowchart of the implementation of the method for testing multiple communication protocols according to an embodiment of the present application, which is applied to a communication protocol testing terminal, and is described in detail as follows:

[0027] S101: Select a communication protocol between the target device.

[0028] In this embodiment, the target device can be the monitoring host described above, and the communication protocol testing terminal is used to simulate multiple acquisition terminals and communicate with the monitoring host. The following takes the monitoring host as the target device to explain the method for testing multiple communication protocols provided by the present application. It can be understood that the target device can also be other devices with multiple communication protocols.

[0029] Specifically, when the user needs to test the communication protocol between the monitoring host and a certain acquisition terminal, the communication protocol between the two is first obtained, which includes but is not limited to CAN communication protocol, Modbus communication protocol and 7E communication protocol. Different communication protocols correspond to different protocol analysis functions.

[0030] In one possible implementation, before S102, the method provided by the present embodiment further includes:

[0031] Obtaining the communication mode corresponding to the target communication protocol selected by the user, and establishing a communication connection with the target device through the communication mode.

[0032] In this embodiment, at least one communication mode can be included under various communication protocols, including serial communication, network communication, etc. Some communication protocols can only be connected through network communication, or only through serial communication, and some communication protocols can be connected through multiple communication modes, such as the modbus communication protocol which can be connected through network or serial port. After the communication protocol is determined, the communication protocol testing terminal can display at least one communication mode option corresponding to the selected communication protocol on the display interface for the user to select. After the user selects the communication mode, the communication protocol testing terminal establishes a communication connection with the monitoring host through the selected communication mode.

[0033] S102: Calling the protocol analysis function corresponding to the target communication protocol, analyzing the query packet sent by the target device, and determining the protocol measurement point carried in the query packet.

[0034] In the embodiment, after the communication protocol test terminal establishes a communication connection with the monitoring host, the monitoring host sends a query message of regular data to the communication protocol test terminal. After receiving the query message, the communication protocol test terminal calls a corresponding analysis function of the communication protocol to analyze the query message, and determines the protocol test point carried in the query message through a function code in the query message. The protocol test point information carried in the query message can be a test point ID (identity).

[0035] In one possible implementation, before S103, the method provided in the embodiment further includes:

[0036] Obtaining communication protocol content of the target communication protocol;

[0037] Identifying data names of each data in the communication protocol content, and converting the communication protocol content into a protocol content test table based on the data names of each data, and displaying the protocol content test table;

[0038] The communication protocol content includes a test point identification number, a test point description and simulation values corresponding to each protocol test point.

[0039] In the embodiment, each communication protocol includes corresponding communication protocol content. In order to facilitate a user to view the communication protocol content, the embodiment designs a communication protocol content display box in a display interface of the communication protocol test terminal, and sets an import button. The user clicks the import button, selects a storage address of the communication protocol content, finds a communication protocol content file, imports the communication protocol content file, automatically identifies data names of each data in the communication protocol content, determines protocol content corresponding to different protocol test points, and then inserts the communication protocol content corresponding to each protocol test point into each column title (or row title) in the protocol content test table, with each row (column) in the table corresponding to the communication protocol content of one protocol test point, to obtain the protocol content test table. Finally, the protocol content test table is displayed in the communication protocol content display box, as shown in Figure 3

[0040] In the embodiment, taking the data names as column titles as an example, the zoom ratio of the protocol content test table in the communication protocol content display box can be determined based on the number of column titles. When the number of column titles is small, the zoom ratio is large, and when the number of column titles is large, the zoom ratio is small, so that the communication protocol content display box can display all data names in the communication protocol content.

[0041] Specifically, as shown in Figure 3 The communication protocol content includes a test point identification number (ID), a test point description, a register address, a size end, an amplification coefficient, precision, a register type, a display value and a plurality of simulation values.​

[0042] The communication protocol test terminal can also acquire user operation on a simulation value in the protocol content test table. If double-click operation on a table of a simulation value is monitored, the table enters an editing mode, and the user can edit data in the table. The communication protocol test terminal saves the simulation value edited by the user in real time.

[0043] S103: The simulation value corresponding to the protocol measurement point carried in the query message is spliced into a reply message by using a protocol analysis function corresponding to the target communication protocol, and the reply message is sent to the target device, so that the target device analyzes the reply message and obtains data corresponding to the protocol measurement point.

[0044] In one possible implementation, each protocol measurement point includes at least one simulation value, and the specific implementation process of S103 includes:

[0045] The simulation value column number selected by the user is obtained, and the simulation value column number selected by the user is used as a first column number.

[0046] The simulation value of the first column number corresponding to the target protocol measurement point in the protocol content test table is found as a target simulation value, and the target protocol measurement point is the protocol measurement point carried in the query message.

[0047] The target simulation value is spliced into the reply message by using a protocol analysis function corresponding to the target communication protocol.

[0048] In this embodiment, since each protocol measurement point in the protocol content test table corresponds to multiple simulation values, in order to determine the simulation value to be returned, the display interface can be provided with a simulation value selection item, and column titles (for example, simulation value 1, simulation value 2, and simulation value 3) of multiple simulation values are provided in the simulation value selection item. After the user selects a column title of a simulation value, the communication protocol test terminal captures data of the protocol measurement point carried in the query message in the protocol content test table under the column title of the simulation value, and then takes the data as a target simulation value. The target simulation value is spliced into the reply message by using a corresponding protocol analysis function.

[0049] S104: The data of the protocol measurement point returned by the target device is obtained, and a test result of the protocol measurement point is determined based on the data and the simulation value corresponding to the protocol measurement point.

[0050] In this embodiment, after the target device receives the reply message sent by the communication protocol test terminal, it parses the reply message to obtain the data corresponding to the target protocol test point, thereby simulating the process of the monitoring host acquiring data from the acquisition device. To test whether the communication protocol on the target device side is correct, the terminal device can use a crawler program to obtain the data of the target protocol test point parsed by the target device and display it in the protocol content test table. The communication protocol test terminal judges whether the simulated value of the column header corresponding to the target protocol test point is consistent with the corresponding data crawled from the target device. If they are consistent, the communication protocol test result of the acquisition function is determined to be normal; if they are inconsistent, the communication protocol test result of the acquisition function is determined to be abnormal.

[0051] In one possible implementation, after S101, the method provided in this embodiment further includes:

[0052] Displays the functional modules corresponding to the target communication protocol.

[0053] In this embodiment, as Figure 3 As shown, each communication protocol in the communication protocol test terminal includes multiple different functions. For example, data display, alarm toggle, and search functions. After each function is executed, the communication protocol test terminal can synthesize the corresponding function execution result into a message using the corresponding protocol parsing function and send it to the target device. The target device then parses the received message using the corresponding protocol parsing function to obtain the corresponding function execution result.

[0054] In this embodiment, the display interface of the communication protocol testing terminal can be pre-set with the layout of various functions, and after the target communication protocol is determined, the corresponding functional modules will be displayed, while functional modules that are not present in the target communication protocol will be hidden.

[0055] In this embodiment, the application integrates multiple protocol parsing functions into the communication protocol testing terminal. During the function development process, if a new function for a certain communication protocol is added, it is determined whether the function is a general function. If the function is a general function, only one set of logic code needs to be developed, and different protocol parsing functions can be called during subsequent use. If the function is not a general function, the logic code for that function is developed, and the corresponding protocol parsing function is called directly in the future. In this way, function development time can be greatly saved.

[0056] From the above embodiment, the embodiment can shorten the pre-use proficiency time of the tester for different test tools, greatly save the pre-test time, and improve the test efficiency. In addition, the application can realize the test process of opening only one tool to monitor the test and verification of multiple southbound protocols in the host, reduce the computer resource occupation, reduce the tool flashing risk, and reduce the later maintenance cost.

[0057] It should be understood that the size of the serial number of each step in the above embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the application.
