Problems solved by technology

[0003] The above-mentioned technical scheme can only send the derailment information to the monitoring center in a different place. Although it has played an alarm role, it cannot promptly notify the derailed locomotive and nearby locomotives to take effective protective measures when derailing, so that the train is very easy to continue to slide after derailing and cause For secondary accidents such as collision and rollover, if the early warning method and early warning system of the prior art are used, the best time to prevent the secondary accident of the train will be missed, and the derailed locomotive cannot be braked in time.

Embodiment Construction

[0019] In the present invention, at the beginning of the derailment of the vehicle, the early warning information is automatically sent and the emergency braking of the locomotive is controlled to prevent the secondary accident of the train from happening, and the derailment signal of the locomotive is collected through the sensor connected to the rail and the acceleration sensor installed in the locomotive cab. Send vehicle derailment warning information to the derailed locomotive 100 and nearby locomotives by means of wireless digital transmission, and take emergency braking measures for the vehicles. Below, will refer to figure 1 , figure 2 with image 3 A detailed description.

[0020] According to the automatic early warning method for vehicle derailment provided by the present invention, in step a, the gravity sensor 2 is installed on the sensor connecting rod 1 between the two rails. When a derailment accident occurs, the wheel will break away from the original rail ...

Abstract

The invention relates to a car derailment warning method, which comprises the following steps: a sensor is mounted on a sensor connecting rod between two rails; when derailed wheels press the sensor connecting rod, the sensor sends out derailment signals to ground control equipment; a main control unit of the ground control equipment receives the derailment signals and sends out derailment early warnings and emergency breaking instructions; a coding unit codes the derailment early warnings and emergency breaking instructions and sends coded instructions to a derailed train and a nearby train by a transmitter; a vehicle station located on the derailed train or the nearby train receives and analyzes the derailment early warnings and emergency breaking instructions; a breaking device of the train is initiated to stop the train. The car derailment automatic early warning system comprises the sensor connecting rod, the sensor, the main control unit, the coding unit, the transmitter and the vehicle station. The method and system of the invention can avoid the occurrence of a secondary accident to the train after derailment and reduce loss of casualty and property caused by the accident.

Description

technical field [0001] The invention relates to an automatic early warning method for vehicle derailment and an automatic early warning system for vehicle derailment. Background technique [0002] The early warning system in the prior art includes a GPRS module. When a derailment accident occurs, the monitored derailment information is sent to a monitoring center in a different place through the GPRS module for alarming. [0003] The above-mentioned technical scheme can only send derailment information to the monitoring center in a different place. Although it has played an alarm role, it cannot promptly notify the derailed locomotive and nearby locomotives to take effective protective measures when derailing, so that the train is very easy to continue to slide after derailing and cause For secondary accidents such as collision and rollover, if the early warning method and early warning system of the prior art are adopted, the best opportunity to prevent the secondary accide...
