Description
Technical Field
The invention belongs to the technical field of automatic software control, and particularly relates to a DMI software automatic control method and system based on a virtual serial port.
Background
In the field of rail transit, a Driver Machine Interface (DMI), also called a Driver-vehicle device Interface, is a platform for communication between a Driver and a vehicle device. Through the DMI man-machine interface, a driver can acquire a series of driving information such as running speed, alarm speed, distance from a pattern drawing point and the like; on the other hand, the driver also needs to send control commands to the ATP (automatic train protection) through the DMI human machine interface.
In order to ensure safe and reliable train running, potential errors or defects are found, and test work is carried out. As shown in fig. 1, the conventional detection mode is usually realized through hardware key control, the hardware key control includes manual control and mechanical arm control, the hardware key sends the acquired information to the serial port, and the serial port sends the information to the DMI software. But the hardware key control speed is slow, the automatic test is difficult to realize, and the test efficiency is not high; when the DMI human-computer interface is controlled and information is recorded, because the DMI human-computer interface has radiation, a tester needs to manually control the keys for a long time in the operation process, and the long-time radiation irradiation can influence the health of the tester; and the mechanical arm is large in size and difficult to realize desktop-level test.

The man-machine interaction interface software system consists of a button response system and an interface display system, wherein the button response system comprises a vehicle-mounted man-machine interface and two controllable keyboards. When the digital tram vehicle-mounted man-machine interaction system is in an input state, the fixed function key is operated by a driving program, and the input information of the driving program is displayed in an input frame by a vehicle-mounted man-machine interface; the expandable function keys are divided into three levels of menus: pressing keys in the first-level menu to enter a second-level menu; pressing a key in the second-level menu to enter a third-level menu; for example, when the train is in a stop state, the driver presses a 'data' key in the first-level menu of the extensible function keys to enter the second-level menu; then pressing a 'train data' key in the second-level menu to enter a third-level menu; in the third level menu, there are three keys, "confirm", "delete", and "cancel". The driver inputs a new train length by operating the fixed function key and then presses the "ok" button in the three-level menu of the extensible function key. In conclusion, in the application, when the vehicle-mounted human-computer interaction system of the train is controlled, the driver needs to manually press the operable keyboard, and automatic interaction cannot be realized.
