The metal sheath of the first cable and the shielding layer of the second network cable are connected to the metal inner layer of the electronic protection box; the display controller is connected to the information display console through the third cable and the fourth network cable. The third cable has a metal sheath and the fourth network cable has a shielding layer. The metal sheath of the third cable and the shielding layer of the fourth network cable are respectively connected to the metal inner layer of the electronic protection box and the grounding of the equipment cabinet in the railway signal room.

[0107] In the embodiment of the present invention, the information display console is connected to the display controller via a network cable and a cable, and the display controller is further connected to the liquid crystal display via a network cable and a cable. As an optional embodiment, the railway signal equipment house is located in the station signal building, and the information display console can be but not limited to an industrial control computer, equipped with a communication module to achieve information interaction with the display controller, and powered by the existing signal power supply equipment in the station signal building.

[0108] In the embodiment of the present invention, the maintenance manager of the railway signal room equipment can input the railway signal room equipment information to be displayed through the information display console, and the information display console transmits the input railway signal room equipment information to the corresponding display controller, and the display controller displays the received railway signal room equipment information on the liquid crystal display. As an optional embodiment, the display controller is also used to monitor the working state of the information display node device composed of the display controller, the liquid crystal display and the electronic protection box. When the working state of the information display node device is abnormal, the display controller outputs an alarm message and transmits it to the information display console. After receiving the alarm message, the information display console gives an alarm prompt to remind the maintenance manager of the railway signal room equipment to handle it.
