Abstract
The invention relates to a train speed limiting device, belonging to the technical field of railway transportation. In the running process of a train, the train speed needs to be controlled in some special sections. If the train speed is controlled only by a train driver, great potential safety hazards exist, for example, fatigue driving and incorrect operation of the train driver result in that the train does not run at a specified speed, and inestimable loss can be caused to lives and property of people. The invention aims to solve the technical problem of enabling the train to run at the specified speed absolutely in some special sections of the railway line. To solve the problem, the invention has the technical scheme that a sensor chip or a signal emitting device is placed on the starting railway line of the special section on the railway line requiring to limit the train speed; when the train wheel is in contact with the sensor chip or the train is in contact with the signal emitting device on the rail, signals are emitted; and a signal receiving device in the train transmits the speed requirement information in the sensor chip or the speed information requirement emitted by the information emitting device to a train speed control device, so that the train speed is effectively controlled.
Description
Technical field is: the railway traffic transportation
Background technology: train is in operational process, and in some highway section, train running speed must limit.The train speed limit was by the engine driver train to be operated in the past, if engine driver's fatigue driving and maloperation all can cause train not travel by as prescribed, this has just increased the hidden danger of train safe operation greatly.Unsafe problems occurs in the train running in order to avoid, and the present invention adopts automatic pressure to limit train speed.
Summary of the invention: 1. invented in the train running process, the position to train speed need limit is provided with sensing chip on the pairing track for a train in this position, or places signal and send out and establish device on the pairing track for a train in this position.
2. after train wheel touches sensing chip, induced signal is passed to signal receiving device on the train; Or train touches the signal of sender unit emission, and signal is passed to the signal receiving device on the train.
3. the signal receiving device on the train is passed to the train speed control setup with signal
4. the sensing chip making current on the track, the numerical value of each electric current is corresponding to a kind of desired train speed, and current values should be placed sender unit on the track in safe range, the corresponding a kind of desired train speed of each signal emissive porwer.
5. speed control unit controls the running velocity of train on the train according to received signal strength.
The specific embodiment
In the train running process, to the position that train speed need limit, on the pairing track for a train in this position, place sensing chip, or on the pairing track for a train in this position, place sender unit; After train wheel touches sensing chip, induced signal is passed to signal receiving device on the train; Or train receives the signal of sender unit emission, and signal is passed to the receiving device on the train, and the signal receiving device on the train is passed to train speed with signal and controlled device; Sensing chip on the track is by electric current, and the numerical value of each electric current is corresponding to a kind of desired train speed; If place sender unit on the track, the corresponding a kind of desired train speed of each signal emissive porwer controls speed device and moves by desired speed according to received signal intensity control train on the train; The train speed device is provided with the speed closing appliance, if need adjust train speed at this traffic coverage, then need open closing appliance earlier, and the locking directive command is responsible for by the special messenger; At need cancellation restriction train speed place, place sensing chip or sender unit on the track for a train herein once more.The qualification speed of the cancellation of intensity of current in the sensing chip or sender unit transmit signal strength representative herein train; The train signal receiving device receives the signal that the cancellation train limits speed, and this signal is passed to the train speed control setup; Train speed controls device to the train speed automatic unlocking.
