an outdoor LEU equipment working condition monitoring device

Abstract

The invention discloses an outdoor LEU equipment working state monitoring device, which comprises a temperature and humidity sensor, an image sensor, a monitoring extension, a communication host and an industrial control computer. The temperature and humidity sensor is arranged in an LEU equipment cabinet, and the image sensor is installed on the LEU cabinet. The temperature and humidity sensor and the image sensor are respectively connected with a monitoring extension through a data line, the monitoring extension is connected with a communication host through the data line, and the communication host is connected with an industrial control computer. The LEU equipment working status indicator lamp is reflected to the camera in the camera support through the reflector, the camera transmitsthe image data to the monitoring extension, after the monitoring extension processes, the image data is transmitted to the industrial control computer through the network host computer, and the workercan view the LEU equipment on the industrial control computer. In the same case, the temperature and humidity sensor data are transmitted to the industrial control computer in the same path for inspection by the staff.

Description

technical field [0001] The invention relates to the field of railway signal equipment, in particular to an outdoor LEU equipment working state monitoring device. Background technique [0002] LEU refers to Lineside Electronic Unit line side electronic equipment. With the increasing speed of trains, only relying on the way of sending blockage information to on-board equipment by track circuits can no longer meet the requirements of safe high-speed train running in terms of information volume. It is necessary to increase transponder equipment to provide a large number of fixed information and variable information. LEU is a data transmission device, which is used to receive the data message sent by the train control center and send it to the active transponder. The outdoor LEU equipment is to prevent the attenuation of the train control transmission signal. The cabinet of the LEU equipment is installed beside the track far from the signal mechanical room, and communicates wit...

AI Technical Summary

Problems solved by technology

[0003] The LEU equipment has an indicator light to indicate the working status of the equipment, but it is located beside the track far from the signal machinery room. The working status of the equipment (operation status indicator light) cannot be known to the signal maintenance personnel in a timely and intuitive manner, and the signal maintenance personnel can only be passive. Only when there is a problem or failure of the LEU equipment and the transponder does not work properly can it respond, which brings great hidden dangers to the driving safety of the high-speed railway.
