At the same time, we can adjust the machine in a timely manner according to the current operating status, so that the operation of the machine can tend to be executed in the direction of human control.

[0003] Existing industrial monitoring equipment usually monitors data based on the modbus RTU protocol. However, the monitoring equipment in the prior art is large and inconvenient to carry. In addition, the corresponding monitoring equipment usually requires external equipment wiring and debugging, cannot realize wireless communication to obtain data, the wiring operation is complicated, the data storage space is small and it is not convenient to export data for problem analysis, cannot flexibly obtain real-time data for data analysis operations, cannot judge the status and accuracy of the data, and realize data verification. Summary of the invention

[0004] The purpose of this application is to provide a data verification method, device, electronic device and storage medium, which can quickly and easily view and verify the data of the monitoring equipment without complicated wiring operations, making the data verification of the monitoring equipment more flexible, and can obtain the data status in time to realize dynamic verification of the data.

[0010] The data to be verified is verified to obtain a verification result.

[0011] In the above implementation process, the target data in the return data sending queue data obtained according to the polling instruction is obtained to obtain the data to be verified for verification. The data of the monitoring device can be checked quickly and easily without complicated wiring operations, making the data verification of the monitoring device more flexible, and the data status can be obtained in time to realize dynamic verification of the data.

[0012] Furthermore, the step of obtaining the returned data according to the polling instruction includes:

[0013] Sending a first polling instruction in the polling instructions, determining whether first return data corresponding to the first polling instruction is received within a first time threshold, and determining that the first return data is the return data;

[0014] If yes, send the second polling instruction in the polling instruction, obtain the second return data corresponding to the second polling instruction, and determine that the second return data is the return data, until all polling instructions in the polling instruction are sent;

[0015] If not, a timeout timer is enabled according to the first function, first return data after timeout corresponding to the first polling instruction is obtained, and the first return data after timeout corresponding to the first polling instruction is determined to be the return data.

[0016] In the above implementation process, polling instructions are issued in sequence, and return data is received within a preset time threshold. Limiting the receiving time of the return data can ensure the real-time nature of data verification and avoid affecting the data status due to too long a time.

[0020] If not, determine whether the queue data contains data that needs to be sent. If the queue data contains no data that needs to be sent, enable the polling delay timer according to the third function.

[0021] In the above implementation process, when the first return data after timeout corresponding to the first polling instruction is received within the second time threshold of the timeout timer, the first return data after timeout corresponding to the first polling instruction is parsed in time to ensure the accuracy of the data and reduce data errors.

[0026] Furthermore, the step of matching the frame header data of the response data according to the target instruction in the instruction buffer of the queue data to obtain the first array includes:

[0027] Matching the frame header data with the slave number and function code in the target instruction to determine whether the target byte data of the frame header data is matched;

[0028] If so, determine that the frame header data is correct data, mark the frame header position, and obtain the first array.

[0029] In the above implementation process, the frame header data is matched according to the slave number and the function code, so that the accuracy of the frame header data can be accurately verified, support can be provided for subsequent data verification, and the flexibility of data verification can be improved.

[0030] Furthermore, the step of verifying the data to be verified and obtaining a verification result includes:

[0031] Determine whether the target byte of the data to be verified is a preset length;

[0032] If so, determine that the data to be verified is correct data, obtain the verification code of the data to be verified, and determine whether the verification code is correct. If the verification code is correct, clear the data according to the fourth function.

[0033] In the above implementation process, the accuracy of the data to be verified is determined according to the length of the target byte, and the check code of the data to be verified is further verified, which can improve the accuracy of the verification, avoid verification errors, and improve the verification efficiency.

[0049] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0050] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0051] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0052] Embodiment 1

[0053] Figure 1 is a flow chart of a data verification method provided in an embodiment of the present application, such as Figure 1 As shown, the method includes:

[0054] S1, obtain the initialized queue data;

[0055] S2, obtain the returned data according to the polling instruction;

[0056] S3, sending the target data in the queue data according to the returned data to obtain the response data;

[0057] S4, parsing the response data to obtain the data to be verified;

[0058] S5, verifying the data to be verified and obtaining a verification result.

[0059] In the above implementation process, the target data in the return data sending queue data obtained according to the polling instruction is obtained to obtain the data to be verified for verification. The data of the monitoring device can be checked quickly and easily without complicated wiring operations, making the data verification of the monitoring device more flexible, and the data status can be obtained in time to realize dynamic verification of the data.

[0060] In S1, the queue data sent by the server is initialized. The embodiment of the present application performs polling based on the polling rule of the modbusTCP protocol, obtains the register data / parameter return data sent by the slave by sending a polling instruction, and the slave makes a passive response.

[0061] Furthermore, S2 includes:

[0062] Sending a first polling instruction in the polling instructions, determining whether first return data corresponding to the first polling instruction is received within a first time threshold, and determining that the first return data is return data;

[0063] If yes, send the second polling instruction in the polling instruction, obtain the second return data corresponding to the second polling instruction, and determine that the second return data is the return data, until all polling instructions in the polling instruction are sent;

[0064] If not, the timeout timer is enabled according to the first function, the first return data after the timeout corresponding to the first polling instruction is obtained, and the first return data after the timeout corresponding to the first polling instruction is determined to be the return data.

[0065] In the above implementation process, polling instructions are issued in sequence, and return data is received within a preset time threshold. Limiting the receiving time of the return data can ensure the real-time nature of data verification and avoid affecting the data status due to too long a time.

[0066] When the host sends a polling instruction, it will confirm whether the response timeout has occurred based on the response time of the return data from the slave. There may be multiple polling data in each polling cycle. In the embodiment of the present application, two different polling instructions are used as one polling cycle. When the response time exceeds the first time threshold, the polling timeout occurs, and then the timeout timer is enabled again. The next polling data is sent according to the polling delay time, and so on.

[0067] Optionally, the first function of the embodiment of the present application may be a List.pushBack(list, value) function.

[0068] During the polling process of the present application, when the response time meets the requirement of the first time threshold, the slave number subscript curSlaveIndex and the address number subscript curCmdIndex corresponding to the polling instruction are respectively increased by 1. By judging whether the current queue value exists in the queue through the curSlaveIndex subscript value, the order of the polling instructions sent is ensured to follow the first-in-first-out principle.

[0069] Furthermore, the step of obtaining the first returned data after the timeout corresponding to the first polling instruction also includes:

[0070] Determine whether first returned data after timeout corresponding to the first polling instruction is received within a second time threshold corresponding to the timeout timer;

[0071] If yes, perform data analysis on the first returned data after the timeout according to the second function;

[0072] If not, determine whether there is data in the queue that needs to be sent. If there is no data in the queue that needs to be sent, enable the polling delay timer according to the third function.

[0073] In the above implementation process, when the first return data after timeout corresponding to the first polling instruction is received within the second time threshold of the timeout timer, the first return data after timeout corresponding to the first polling instruction is parsed in time to ensure the accuracy of the data and reduce data errors.

[0074] The timeout timer is enabled. If the corresponding data is received (the first returned data after the timeout corresponding to the first polling instruction), the data parsing callback is implemented according to the on_mb_recv_data(packet) function (the second function).

[0075] If no response is received, it is determined whether there is data to be sent in the current queue data. If there is no corresponding data to be sent in the queue data, the polling delay timer is started and the next polling data is sent, and so on. When all polling instructions in a polling cycle are executed, the polling ends. Optionally, the third function can be the same function as the first function, which is used to start the timer.

[0076] Furthermore, S4 includes:

[0077] Matching the frame header data of the response data according to the target instruction in the instruction buffer of the queue data to obtain a first array;

[0078] The target data in the instruction buffer of the queue data is added to the first array to obtain the data to be verified.

[0079] In the above implementation process, the target instruction in the instruction buffer is matched with the frame header data of the response data, so that the response data can be processed in time and the data redundancy caused by the response data can be reduced.

[0080] The response data will trigger on_mb_recv_data(packet). The embodiment of the present application performs data parsing according to the modbusTCP protocol. The data parsing triggers the callback in byte mode, which is obtained in the instruction buffer.

[0081] Further, the step of matching the frame header data of the response data according to the target instruction in the instruction buffer of the queue data to obtain the first array includes:

[0082] Match the slave number and function code in the target instruction with the frame header data to determine whether the target byte data of the frame header data is matched;

[0083] If so, determine that the frame header data is correct data, mark the frame header position, and obtain the first array.

[0084] In the above implementation process, the frame header data is matched according to the slave number and the function code, so that the accuracy of the frame header data can be accurately verified, support can be provided for subsequent data verification, and the flexibility of data verification can be improved.

[0085] The embodiment of the present application matches the frame header data using a for loop, starting from i and ending at #packet (the last received byte index). The frame header data is found by corresponding judgment, and the first two bytes of a frame of complete data correspond to the slave number and function code. If the corresponding correct data is received, the flag position of the frame header data is 1, and the data is added to the buff array (the first array) to obtain the data to be checked.

[0086] Furthermore, S5 includes:

[0087] Determine whether the target byte of the data to be verified is a preset length;

[0088] If so, determine that the data to be verified is correct data, obtain the verification code of the data to be verified, and determine whether the verification code is correct. If the verification code is correct, clear the data according to the fourth function.

[0089] In the above implementation process, the accuracy of the data to be verified is determined according to the length of the target byte, and the check code of the data to be verified is further verified, which can improve the accuracy of the verification, avoid verification errors, and improve the verification efficiency.

[0090] Determine the data length of the third byte (target byte) of a complete frame of data received. The data structure is: slave number (1 byte) - function code (1 byte) - data length (1 byte) - register data (several bytes, based on the data length) - CRC16 check (2 bytes). The data in the first array is a complete frame of data. At the same time, determine whether the received CRC16 check code is correct. If it is correct, execute the cmd_list_check_ack (user_cmd_buff) function (the fourth function), which mainly displays the currently read register data. At the same time, clear the current first array and clear the corresponding count variable.

[0091] The embodiments of the present application can quickly and flexibly realize real-time parameter acquisition and verification data through wireless processing, and can realize the function of exporting verification data to an SD card or USB flash drive, and support opening files on a computer to view real-time data.

[0096] The parsing module 3 is used to parse the response data to obtain the data to be verified;

[0097] The verification module 4 is used to verify the data to be verified and obtain the verification result.

The data of the monitoring device can be checked quickly and easily without complicated wiring operations, making the data verification of the monitoring device more flexible, and the data status can be obtained in time to realize dynamic verification of the data.

[0099] Furthermore, the data acquisition module 2 is also used for:

[0100] Sending a first polling instruction in the polling instructions, determining whether first return data corresponding to the first polling instruction is received within a first time threshold, and determining that the first return data is return data;

[0101] If yes, send the second polling instruction in the polling instruction, obtain the second return data corresponding to the second polling instruction, and determine that the second return data is the return data, until all polling instructions in the polling instruction are sent;

[0102] If not, the timeout timer is enabled according to the first function, the first return data after the timeout corresponding to the first polling instruction is obtained, and the first return data after the timeout corresponding to the first polling instruction is determined to be the return data.

[0103] In the above implementation process, polling instructions are issued in sequence, and return data is received within a preset time threshold. Limiting the receiving time of the return data can ensure the real-time nature of data verification and avoid affecting the data status due to too long a time.

[0104] Furthermore, the data acquisition module 2 is also used for:

[0107] If not, determine whether there is data in the queue that needs to be sent. If there is no data in the queue that needs to be sent, enable the polling delay timer according to the third function.

[0108] In the above implementation process, when the first return data after timeout corresponding to the first polling instruction is received within the second time threshold of the timeout timer, the first return data after timeout corresponding to the first polling instruction is parsed in time to ensure the accuracy of the data and reduce data errors.

[0113] Furthermore, the parsing module 3 is also used for:
