Embodiment Construction

[0028] The invention is composed of a crossing monitoring mechanism, a crossing signal transmission mechanism, a relay transmission mechanism, a railway locomotive monitoring mechanism and a central processing mechanism. The camera infrared camera of the crossing monitoring agency, the transmitter of the crossing signal transmission mechanism, and the solar panel are all installed on the poles at the crossing and in the crossing machine room; the locomotive monitoring agency includes a microwave transceiver device, a locomotive signal processing device, and a screen monitoring device. It is installed in the cab of the locomotive; the crossing signal receiving device, the sound and light alarm device, and the guardrail device are installed at the crossing; the central processing mechanism is installed in the control room; the relay transmission mechanism is installed on the roadside. When the locomotive is 5 kilometers away from the crossing, the screen will automatically turn o...

Abstract

The bidirectional monitor and control system is composed of the monitor and control mechanism (MCM) at railroad junction (RJ), relay facility, MCM on rail vehicle, and central processing mechanism. MCM) at RJ transfers the collected situations to the signal transmission mechanism at RJ. Passed through relay of repeater facilities, or turning transmission, the said collected situations are transmitted to MCM on rail vehicle, and displayed through screen. Through microwave, bidirectional transferred situations of train and commands of driver are transferred to signal reception device at RJ; and using signal process device makes RJ know the distance between the train and RJ, and makes guardrail act, red or green lights bright, and alarm sound hoots. Using walkie-talkie, dispatcher in central dispatching room tells driver the status at RJ so as to make dual monitors. The invention lets driver know status at RJ, as well as lets RJ know the distance so as to solve safety issue at RJ.

Description

Technical field: [0001] The invention relates to a monitoring system, in particular to a visual two-way monitoring system for railway crossing safety. Background technique: [0002] my country's current railway crossings are divided into manned and unattended crossings. There are no safety measures for unattended crossings, and people in the passage mainly rely on "stop once, watch twice, and pass three times". After the information that the train will pass, the guardrail is manually put, the red light is turned on and the alarm bell is sounded. This crossing safety system belongs to passive monitoring. As a locomotive driver, he does not know the situation of the crossing. How to enable a high-speed locomotive to monitor various safety conditions at the crossing in real time through image signals at a distance of 3-5 kilometers from the crossing , so that the locomotive can take corresponding measures in advance in an emergency to ensure the safety of the operation and the ...
