[0046] In the embodiments of the present invention, the operation representation and method based on automatic testing are implemented through three parts: simulation software, screen recording software, and platform operation terminal. Among them, the simulation software is deployed in the interlocking / operation representation machine system, responsible for starting other software in the host, simulating mouse operations on the operation representation machine, and performing image recognition on the display interface of the operation representation machine, communicating with the platform operation terminal through the TCP protocol, and obtaining operation / recognition commands. The screen recording software is deployed in the interlocking / operation representation machine system, responsible for recording the operation and display process of the operation representation machine, recording the video data of the test process, communicating with the platform operation terminal through the TCP protocol, and obtaining video recording / stop commands.

The system initialization command includes electrolysis unlocking and starting the simulation. The screen recording software performs recording preparation, which includes, first, the screen recording software sending a request for screen recording parameters to the platform operation terminal. Then, the platform operation terminal feeds back the requested video saving FTP parameters to the screen recording software. The FTP parameters include the path, username, password, and port.

[0048] Step S4: The simulation software performs initialization operations and sends an initialization success flag to the platform operation terminal. Step S5: The platform operation terminal starts automatic testing and sends a start recording command to the screen recording software, and the screen recording software starts recording.

[0053] Step S13: After the platform operation terminal stops the automatic testing, it sends a stop recording command to the screen recording software.

[0054] Step S14: The screen recording software stops recording, saves the file, and uploads it to the FTP.

The operation display machine software, the interlocking host software, and the simulation software are all set in the operator simulation module. Among them, as Figure 2 shown, the data flow of the operator simulation module is as follows: First, during the automatic test process, the simulation software forwards the received test execution command to the operation display machine software. Then, the operation display machine software sends the test execution command to the interlocking host software. Finally, the interlocking host software executes the test execution command and sends the device status information to the simulation software through the operation display machine software.

[0056] In the embodiment of the present invention, the maximum length of the test execution command is a preset number of bytes. Among them, two bytes represent a button state. The device status information transmitted by the operation display machine software to the simulation software is of fixed length. The content of the device status information includes a packet header and several device information packets. Among them, the content of the packet header is the length of the entire data packet. Each device information packet in several device information packets includes a data type, a data length, and data content.

[0057] In the embodiment of the present invention, it also includes that the operation display machine system determines whether to enter the automatic test mode, including that the operation display machine software obtains the automatic test flag through the interface function of the simulation software. The automatic test flag is the return value of the simulation software. Among them, if the return value of the simulation software is true, it means that the current is in the automatic test mode.

[0058] The above method can realize automatic, efficient, and comprehensive testing of the interlocking software and / or the operation display machine to ensure the reliability and safety of the interlocking software and / or the operation display machine.
