A catenary operating state detection device

Abstract

The invention discloses an overhead contact system operation state detecting device which is connected with an image acquisition terminal that is arranged on the top of a rail transit vehicle and is used for acquiring video images of the overhead contact system. A protective cover is arranged outside the image acquisition terminal. The overhead contact system operation state detecting device comprises a processor, a positioning unit, a temperature acquisition unit, a temperature control unit, a signal triggering unit and a power supply control unit, wherein the positioning unit, the temperature acquisition unit, the temperature control unit, the signal triggering unit and the power supply control unit are connected with the processor. The positioning unit comprises a base station positioning module, an inertial navigation module and a satellite positioning module. Through cooperation of the base station positioning module, the inertial navigation module and the satellite positioning module, real-time positioning data of the rail transit vehicle are acquired. The temperature acquisition unit is used for acquiring temperatures inside and outside the protective cover. The temperature control unit is used for adjusting the temperature in the protective cover according to the temperature information inside and outside the protective cover. The signal triggering unit is used for outputting a triggering signal which triggers the image acquisition terminal to acquire the video image of the overhead contact system. The power supply control unit is used for controlling the power supply of the image acquisition terminal.

Description

Technical field [0001] The invention relates to the field of contact nets, in particular to a device for detecting the operation state of the contact nets. Background technique [0002] The catenary is a high-voltage transmission line that is erected in a zigzag pattern over the rails in an electrified railway for the pantograph. The catenary is the main frame of the railway electrification project. It is a special form of transmission line that is erected along the railway line to supply power to the rail vehicles. Therefore, in order to ensure the normal operation of rail transit vehicles, a safety monitoring system for the operation of the catenary must be used to monitor the catenary in real time. [0003] In the prior art, the video image information of the catenary is generally collected by a single or multiple cameras, and abnormal analysis is performed on the catenary based on image processing technology. However, when multiple cameras simultaneously collect the video imag...

Problems solved by technology

[0003] In the prior art, catenary video image information is generally collected by single-channel or multi-channel cameras, and catenary abnormalities are analyzed based on image processing technology. However, when multiple cameras simultaneously collect video image information of catenary, it cannot be well Complete multi-camera synchronous collection of information

[0004] In the prior art, the positioning data acquired by the catenary operation status safety monitoring system is generally installed on the roof of the vehicle with a satellite positioning antenna, and the analog signal is transmitted to the receiver in the vehicle through the antenna. This method is not convenient for wiring, and its Signals can also be inaccurate

[0005] Since the train is running at high speed, its roof installation device has special requirements, its installation position and installation space are subject to many restrictions, and the existing roof control device is not highly integrated.
