The elevator hall call self-checking method according to claim 3, characterized in that: The program version comparison test is performed, the elevator hall call as the operation host sends program version query data to other hall calls, and other hall calls reply with their own program version information after receiving the query, so as to judge the program version of the elevator hall call. If the program version is lower than that of other normal hall calls, the elevator hall call will choose to upgrade its own program data from other hall calls, specifically including: The operation host sends program version query data to other external calls through the communication line, and the program version query data includes query instruction identification, sender information, receiver information, program version request field, timestamp, sequence number, checksum and encryption information; After receiving the query data, other hall calls parse the data and reply with their own program version information, which includes the hall call ID and the current program version number; The operating host receives the reply information of other external calls, parses the program version number of each external call, compares its own program version number with the program version numbers of other external calls, and determines whether there is a version difference. If the program version number of the operating host is lower than that of other external calls, it chooses to upgrade its own program data from other external calls.

5. An elevator call self-checking device, characterized in that: include: A control unit is used to put the elevator into the hall call detection mode, control the elevator master control to release the occupation of the communication line, and set the elevator hall call to the self-detection mode; The display unit is used to display the model, communication ID number and program version number of the elevator call in the self-test mode to verify whether the power supply, microcontroller and display unit of the elevator call are normal; The communication test unit is used to test the communication unit in the self-test mode. It sends test data to the elevator master control through the elevator call as the operation host, and receives the relevant data replied by the elevator master control as the slave. It determines whether the communication unit is normal according to whether the reply data can be received correctly. The input / output test unit is used to perform input / output unit testing in the self-test mode, automatically cross-interconnect the input / output unit communication buttons in the elevator hall call, automatically run the input / output unit button test in the program, and output the results in the display unit to determine whether the input / output of the elevator hall call is faulty; The version comparison and upgrade unit is used to perform program version comparison test in self-detection mode. It uses the elevator hall call as the operation host to send program version query data to other elevator hall calls, receives program version information replied by other elevator hall calls, and determines whether the program version of the elevator hall call is lower than that of other normal hall calls based on the comparison result. If it is lower, it chooses to upgrade its own program data from other hall calls.

6. An elevator hall call self-checking device according to claim 5, characterized in that: The control unit is also used to generate a corresponding self-test report according to the self-test result after the self-test is completed, and store the self-test report in the storage unit or send it to the elevator management system.

7. An elevator hall call self-checking device according to claim 6, characterized in that: The communication test unit also includes an error detection and retry mechanism, which is used to automatically retry sending test data and record an error log if the reply data from the elevator master control is not correctly received during the communication unit test.

8. An elevator hall call self-checking device according to claim 7, characterized in that: The input / output test unit also includes a fault location function, which is used to locate and mark the faulty input / output unit according to the test results during the input / output unit test. The version comparison and upgrade unit also includes a version compatibility check function, which is used to check whether the program version of the elevator hall call is compatible with the program version of other hall calls before the program version comparison test.

9. A computing device, characterized in that The method comprises a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the elevator call self-checking method according to any one of claims 1 to 4 when executing the computer program.

10. A computer-readable storage medium, characterized in that: The storage medium stores a computer program, and when the computer program is executed by the processor, the steps of the elevator hall call self-checking method according to any one of claims 1 to 4 are implemented.
