specific Embodiment approach

[0063] Specific implementation methods include:

[0064] Step 1: Perform wireless coverage and decoding equipment connection to the station, and work normally. When equipment maintenance is required, bring the front-end equipment to the electrical equipment maintenance site.

[0065] Step 2: Connect the front-end equipment in the working area and power on. The camera is adjusted to the position of the equipment being maintained, and the images are collected and output to the local display LCD screen. Adjust the screen to meet the requirements through the LCD.

[0066] Step 3: The video encoder processes the analog AV video signal and converts it into an MPEG-4 media stream. The sound signal is also digitized.

[0067] Step 4: The processed audio and video data are transmitted to the wireless transmission device through the network.

[0068] Step 5: The wireless transmission device converts the received audio and video data into wireless signals and transmits them to the w...

Abstract

The disclosed maintenance method for electric signal device in railway communication field comprises: wireless covering the maintenance area, connecting wireless transmission device with codec, moving the work position of front-end device with video code / decode and wireless transmission on the covered area to collect information on different position and direction, then real-time bidirectional transmitting image and sound for field condition. This invention introduces much convenience to commanders and maintenance staff to solve problem as soon as possible.

Description

technical field [0001] The invention belongs to the technical field of railway communication, and in particular relates to a maintenance method and device for electrical signal equipment. Background technique [0002] The electrical signal equipment is deployed in the signal machinery room, the station yard, and the interval. The maintenance personnel are responsible for the daily maintenance and troubleshooting of the signal equipment. Once the signaling equipment breaks down, it will inevitably affect the normal operation of the train, which requires maintenance personnel to quickly troubleshoot and make the signaling equipment run normally. For relatively simple problems, maintenance personnel can generally solve the problem. For more complicated faults, maintenance personnel need the guidance of the technicians of the electric power section or the road bureau or the command of the leader. The current means are only telephone and static images. If the description of the ...
