The composition of console subsystem of microcomputer interlock system includes: console microcomputer, station field display device, operation device for station watchman to handle operation, voice output and communication interface with other subsystems.

Computer interlock console display device is the most used graphic display. This is true both at home and abroad. The size of the monitor should be 20 inches or 21 inches, considering the distance between the duty officer and the monitor screen. Smaller screens can be used in smaller stations below 20 switches to help reduce costs.

Large station can use multiple screens to display the entire station graphics. The duty officer is not good at viewing the large-size display at a closer distance and the cost is high, so it should not be used. For the hub presentation center, large screen projectors can be used as the display equipment. The graphics display is used as the station equipment, which not only displays rich colors and vivid images, but also can display text, which is used as the output of operation tips and alarm information, and with voice output to make the prompt and alarm content clearer and clearer.

In domestic microcomputer interlocking project, some users are required to use the traditional unit optical disc to take care of the operator's habit and worry about short monitor life and high maintenance cost. In this case, the lighting conditions for the lamp are not obtained from the combination frame, but are controlled by the additional output circuit of the lamp in the console microcomputer. The display effect is exactly the same as in the case of relay interlock, but avoids the large number of connecting cables between the console and the machine room, reducing the workload of construction and maintenance.
