In the embodiment of the present invention, the structures of the three man-machine interaction units are completely the same, and referring to fig. 1, each man-machine interaction unit includes: a man-machine interaction host, a display terminal (OP) and an input device; and the man-machine interaction host is respectively connected with the display terminal and the input device.
The input device mainly includes: a MOUSE (MOUSE) and a Keyboard (Keyboard).
As shown in fig. 2, the man-machine interaction host includes: the CPU module, and the power module, the display module, the voice module, the storage module (the storage module 1 and the storage module 2) which are mutually standby structures, and the Ethernet communication module (the Ethernet communication module 1 and the Ethernet communication module 2) and the serial communication module (the serial communication module 1 and the serial communication module 2) which are mutually redundant structures which are respectively connected with the CPU module;

In the man-machine interaction host, the data storage modules 1 and 2 are standby, the Ethernet communication modules 1 and 2 are redundant, the serial communication modules 1 and 2 are redundant, and the weak links in the aspects of data storage and communication realize double redundancy.
Referring also to fig. 1, three man-machine interaction units communicate with two logical hosts through two network switches. For each man-machine interaction unit, the Ethernet communication module 1 in the man-machine interaction host communicates with M1 and M2 through the network switch 1, and the Ethernet communication module 2 in the man-machine interaction host communicates with M1 and M2 through the network switch 2. The ethernet communication modules 1,2 of the three man-machine interaction hosts communicate with each other through the network switches 1, 2.
In the embodiment of the invention, the first and second man-machine interaction units are the main systems, and two sets of complete terminal equipment including display terminals (namely OP1 and OP 2) corresponding to the man-machine interaction hosts (namely, the man-machine interaction host 1 and the man-machine interaction host 2) and input equipment (namely, MOUSE1, MOUSE2, keyboard1 and Keyboard 2) are also used in parallel, are arranged in an operation duty room, display the station state and the working state of the interlocking system to a vehicle duty operator, receive operation commands and give relevant voice prompts and alarms.

In the scheme, the man-machine interaction host hardware in the three man-machine interaction units is kept consistent, so that the hardware redundancy of the layer 3 is realized.
The following describes the working principle and working principle of the system.
1. The working principle is as follows.
Different pictures are respectively displayed on the display terminals (OP 1, OP 2) of the first and second man-machine interaction units, wherein one display terminal (OP 1) displays the left half part of the station yard interface, and the other display terminal (OP 2) displays the right half part of the station yard interface, and the whole station yard interface is formed by splicing. Meanwhile, any display terminal can display the function of the whole station interface through screen shrinking operation. The two man-machine interaction hosts are operated in parallel, so that the transportation efficiency can be greatly improved.
The man-machine interaction hosts in the first man-machine interaction unit and the second man-machine interaction unit are respectively connected with two logic hosts through each network switch to realize redundant connection, namely one Ethernet communication module in each man-machine interaction host is connected with two logic hosts through one network switch; the man-machine interaction hosts in the first man-machine interaction unit and the second man-machine interaction unit send operation information to two logic hosts in parallel through two network switches, the two logic hosts respectively perform operation processing and are consistent in real time, and the two logic hosts keep synchronous operation and execute partial related outdoor equipment through the two logic hosts; the representation information of the two logical hosts and the system operation information are respectively sent to three man-machine interaction units through two network switches; the three man-machine interaction units interact information through two network switches; the man-machine interaction host in the third man-machine interaction unit receives operation information from the man-machine interaction hosts in the first and second man-machine interaction units through the two network switches.
The man-machine interaction host in the first and second man-machine interaction units is directly connected with the autonomous machine of the CTC system through a serial communication module with a mutual redundancy structure, sends out station site representation information to the CTC system, and receives an operation command of the CTC system; the man-machine interaction host in the third man-machine interaction unit is connected with the centralized monitoring system through serial communication modules which are of redundant structures, and state information of the station yard and the interlocking system is transmitted to the centralized monitoring system in real time.
2. A power supply principle.
The first human-computer interaction unit and the second human-computer interaction unit adopt independent power supply modes, the input power supply of the first human-computer interaction unit is a first path of power supply, and the input power supply of the second human-computer interaction unit is a second path of power supply; the mode effectively solves the problem that the man-machine interaction systems 1 and 2 are powered off simultaneously after faults such as power failure of an input power supply system and tripping of intermediate equipment are avoided, and therefore influences on railway driving safety and transportation efficiency are reduced.
The third man-machine interaction unit selects the first power supply or the second power supply to supply power through the quick switching device, and when one power supply fails, the third man-machine interaction unit automatically switches to the other power supply through the quick switching device, so that the redundant configuration of the power supply input of the man-machine interaction unit 3 is realized.
