As shown in fig. 2, the computing device may also include a memory 203. The memory 203 is used for storing application program codes for executing the scheme of the present application, and the execution is controlled by the processor 202.

The following describes a method for testing a communication protocol according to an embodiment of the present application with reference to the accompanying drawings.
Fig. 3 is a flow chart diagram illustrating a method of testing a communication protocol, according to an exemplary embodiment. As shown in fig. 3, the method for testing the communication protocol may include the following steps.
Step 31: the testing device of the communication protocol obtains the configuration file.
The configuration file comprises a down command and a first response command corresponding to the target communication protocol.
The command (including issuing command and response command) fields of the configuration file in the present application include, but are not limited to, frame header, communication protocol version number, device address, device type, command control word, command information, check field, frame end.
Specifically, the frame header is used to indicate a flag bit for starting transmission of the communication protocol.
The communication protocol version number is used to represent the version number that the communication protocol follows, where the communication protocol typically has multiple versions.
The device address is an address mark of a lower computer (second electronic device in the application), wherein the lower computer cannot communicate if the address is not matched.
The device type is used to represent the device code of the lower computer. For example, air conditioning, diesel engines, batteries, etc. have different equipment codes.
The command control word (corresponding to the response feedback of the lower computer) is used to indicate the code of the command issued by the upper computer (the first electronic device in the present application). For example, the code of the command such as analog quantity, remote control, setting parameter, etc. is acquired. Similarly, the response feedback of the lower computer is used for representing the coding of the content type of the response feedback of the upper computer by the lower computer. For example, command frames are normal, command frame address errors, command frame control command errors, etc.
The command information (corresponding to the response information of the lower computer) includes an information body of the upper computer issuing the command. Similarly, the response information includes an information body of the lower computer response command.
One or more check fields are provided, and the correctness of the transmission data is checked according to a preset check mode.
The end of frame is the communication protocol transmission end character.
The correctness of the transmission data is checked according to a preset check mode because the check field is required. Therefore, in order to facilitate calculation of the check value corresponding to the check field in the command, the configuration file in the present application adopts a file format capable of writing a function. For example, the excel file is used to generate the configuration file, so that a corresponding check function can be written for the check field in the excel file, and one or more check values can be generated in the check field. For other information in the command field, the configuration file may be entered by the relevant personnel line by line according to the communication protocol content.
Optionally, the configuration file may further include one or more of a test command sequence number, a test command name, a number system flag bit, a data type, a data proportion, a transfer data type, a data value, and an end of frame.
Specifically, the test command serial number is used to represent the serial number of the test command on the test interface of the test software.
The test command name is the Chinese description of the displayed test command in the test interface of the test software. For example, analog quantity is obtained, the remote control oil engine is started, the remote control switch power supply is started, and the like.
The number system flag bit is used for indicating the number system of the data in the configuration file. E.g., 10, 16, etc. For example, when the command of 'setting the starting temperature of the air conditioner' is issued, setting parameters are manually filled, 30 degrees of 10 system are filled, which is more convenient and visual than 16 system, and when the flag bit is 10 system, the test software can convert 30 of 10 system into 30 of 16 system (namely 1 EH) and issue.
Data types include floating point types (including double-precision floating point numbers and single-precision floating point numbers), signed integer types, unsigned integer types, character types, and the like. In the command information of the command field, the value may be directly filled in, and then converted to 16 by test software, or to a us information exchange standard code (American standard code for information interchange, ASII) code. In the response information of the command field, the test software converts the 16-ary (or ASII code) value of the relevant 1 or more bytes into a readable 10-ary according to the data type hint.
The data ratio is used to represent the number of transmit integers.
The transmission data type is used to represent a number system when transmitting data in a command field, for example, converting the data in the command field into 16-ary, or ASII code transmission.
The data value is used to represent a numerical value of command information and response information of the display command field according to the above-described number constraint condition.
The end of frame is a data transfer end identifier.
For other information except the command field in the configuration file, the configuration file can be input by related personnel line by line according to the content of the communication protocol.
And then, the testing device of the communication protocol reads the configuration file to obtain a issuing command and a first response command corresponding to the target communication protocol.
Step 32: the test device of the communication protocol sends a down command.
Specifically, the testing device of the communication protocol sends a down command to the second electronic device.
Step 33: the test means of the communication protocol receives a second answer command from the second electronic device.
Wherein, the first response command and the second response command both comprise check fields.
In one possible implementation, the test device of the communication protocol determines the check value of the first response command according to the second response command and a preset formula.
Specifically, after receiving the second response command, the testing device of the communication protocol calls a check function corresponding to a check field of the issuing command in the configuration file, and calculates a check value of the first response command according to parameters and the check function in the second response command.
In the above scheme, the testing device of the communication protocol determines the check value in the first response command according to the preset formula and the second response command. In this way, whether the target communication protocol is adopted between the testing device of the communication protocol and the second electronic equipment or not can be detected according to whether the check value in the second response command is consistent with the check value in the first response command or not, and whether an error occurs in the check value in the second response command in the transmission process can also be detected.
Step 34: and the testing device of the communication protocol determines that the target communication protocol is adopted between the first electronic equipment and the second electronic equipment under the condition that the second response command is consistent with the first response command.
Wherein the first reply command and the second reply command each include at least one parameter.
Specifically, as shown in fig. 4, the method for determining that the second response command is consistent with the first response command by the test device of the communication protocol includes the following steps.
S1, the testing device of the communication protocol executes comparison operation on the parameters in the second response command and the parameters in the first response command.
Specifically, the comparison operation includes: the test device of the communication protocol determines the receiving parameters and the configuration parameters, and determines the first field and the second field, and in the case that the content of the second field is determined to be the same as the content of the first field, the test device of the communication protocol determines that the receiving parameters and the configuration parameters are the same.
The configuration parameters are any one parameter of the first response command, and the receiving parameters are parameters corresponding to the configuration parameters in the second response command. The first field belongs to a configuration parameter, the second field belongs to a receiving parameter, and the length of the first field is the same as that of the second field.
For example, when the configuration parameter is obtained by taking 2 bytes from the frame header to obtain the first field, the receiving parameter is also obtained by taking 2 bytes from the frame header to obtain the second field, and then, in the case that the content of the second field is the same as the content of the first field, the testing device of the communication protocol determines that the receiving parameter and the configuration parameter are the same.
Wherein the lengths of the first field and the second field are related to the data type in the configuration file. For example, the data type in the configuration file is of a character type, the length of the first field and the second field takes 1 byte, or the data type in the configuration file is of an unsigned integer type, the length of the first field and the second field takes 2 bytes, or the data type in the configuration file is of a floating point type, the length of the first field and the second field takes 4 bytes.
S2, under the condition that the parameters in the second response command and the parameters in the first response command are the same, the testing device of the communication protocol determines that the second response command is consistent with the first response command.
In the scheme, the testing device of the communication protocol extracts and compares the fields in the receiving parameters (belonging to the second response command) and the configuration parameters (belonging to the first response command), is irrelevant to the factors such as Chinese character description, byte total length and the like of the parameters, and further improves the universality of the scheme of the test communication protocol.
In this way, the test device of the communication protocol determines that the second response command is consistent with the first response command when the parameters in the second response command are determined to be the same as the parameters in the first response command, and determines that the target communication protocol is adopted between the first electronic device and the second electronic device when the second response command is determined to be consistent with the first response command.
In the application, the testing device of the communication protocol determines the issuing command according to the configuration file, compares the received second response command with the first response command in the configuration file, and determines the communication protocol between the testing device of the communication protocol and the second electronic equipment. In this way, the configuration file is independent of the test program of the device, and when the communication protocol between two devices (such as the test device of the communication protocol and the second electronic device) is tested, only the configuration file required by the device is required to be configured, and the communication protocol between the two devices can be determined by utilizing the universal test program.
