Mobile video monitoring and high-precision positioning command and dispatching system for railway

Abstract

The invention discloses a mobile video monitoring and high-precision positioning command and dispatching system for a railway. The system comprises a mobile terminal, a wireless communication network and a background processing service center; the mobile terminal comprises a GPS unit, a recording unit, a data processing unit, a compressed encoding unit and a voice broadcasting unit. A collected video stream is pushed to a background server in real time via a handheld terminal integrated with a high-precision GPS chip based on a currently most popular RTMP live broadcasting protocol, meanwhile a current location is positioned by the high-precision GPS chip, a GPS coordinate is uploaded to the server, a command center can open a video in live broadcasting at any time via a management website for watching, and meanwhile, field personnel can be commanded and scheduled by voice or characters; the background server also has a function of storing the live video in real time, and command staffs can also check any video at any time after live broadcasting and meanwhile can check a moving trail of rail operation personnel within a period.

Description

technical field [0001] The invention relates to the technical field of railway track monitoring and command and dispatching, in particular to a real-time monitoring system based on a wireless communication network that integrates real-time mobile live broadcasting of handheld terminal equipment and traditional cameras. Background technique [0002] With the rapid development of railway technology, the scope of railway tracks is getting larger and larger. The current video surveillance system uses fixed-point surveillance cameras to monitor specific locations. The picture is not clear and the cost is too high. Feedback to the railway command center in a timely manner. Even if there are staff to handle it, the on-site situation cannot be clearly fed back to the command center. The command center does not know the details of the scene and the specific location of the track operators. It can only communicate with the operators through walkie-talkies or mobile phones. , to carry ...

Problems solved by technology

[0002] With the rapid development of railway technology, the scope of railway tracks is getting larger and larger. The current video surveillance system uses fixed-point surveillance cameras to monitor specific locations. The picture is not clear and the cost is too high. Feedback to the railway command center in a timely manner. Even if there are staff to handle it, the on-site situation cannot be clearly fed back to the command center. The command center does not know the details of the scene and the specific location of the track operators. It can only communicate with the operators through walkie-talkies or mobile phones. , to carry out real-time command and dispatch work, so how to expand the scope of video surveillance while controlling costs, and how to timely and accurately feed back the on-site operation situation to the command center are important issues that need to be solved urgently
