Method for improving operation density of rail vehicles and preventing head-on collision and rear-ending collision

摘要

The present invention provides a method for improving operation density of rail vehicles and for preventing head-on collision and rear-ending collision. Said method divides a rail line into equidistant electronic zones, the length of a zone being greater than the shortest safe distance between two running vehicles. Said method installs a locomotive passing detection alarm device in each zone, when a locomotive travels at high speed on the rail, the locomotive passing detection alarm device corresponding to the zone occupied by the locomotive itself will simultaneously access adjacent front and back zones, and determine whether the two adjacent zones are simultaneously occupied by locomotives. If the two adjacent. zones are simultaneously occupied by locomotives, the locomotive passing alarm device will send an alarm signal to the locomotives to warn or otherwise take measures. The aforesaid method can avoid locomotive head-on collision and rear-end collision and increase transportation density according to the vehicle speed and distance at the same time, thus improving the transportation efficiency.

1. A method for improving operation density of rail vehicles and for preventing head-on collision and rear-ending collision comprising
dividing a rail line into equidistant electronic zones each with a length greater than the shortest safe distance between two running vehicles and installing a locomotive passing detection alarm device (Mi) in each of the zones, wherein the locomotive passing detection alarm device comprises a whole range sensor component disposed within each of the zones, wherein a signal processing circuit is connected to a signal output terminal of the whole range sensor component, and wherein an alarm signal transmitting circuit (IC3) is connected to the output terminal of the signal processing circuit, transmitting a signal from the signal processing circuits in each zone to signal processing circuits in each adjacent zone; wherein when a first rail vehicle occupies one of the zones (Li), the signal processing circuit of the locomotive passing detection alarm device (Mi) generates an Li occupied signal, wherein when the first rail vehicle exits the zone (Li) and enters the onward adjacent zone (Li+1), the signal processing circuit of the locomotive passing detection alarm device (Mi+1) corresponding to the adjacent zone Li+1 generates an Li+1 occupied signal and transmits the Li+1 occupied signal to the signal processing circuit of the locomotive passing detection alarm device Mi, which changes the Li occupied signal to an Li free signal, wherein when zone Li is occupied by the first rail vehicle and adjacent zone Li+1 is occupied by a second rail vehicle, and each of the signal processing circuits of the locomotive passing detection alarm devices Mi and Mi+1 simultaneously transmit an occupied signal to the opposite signal processing circuit, a trigger signal is generated by each of the signal processing circuits to initiate an alarm signal transmitting circuit to give an alarm signal to each of the rail vehicles in zones Li and Li+1.
