Problems solved by technology
[0003] Prior art CN105480250B discloses an anti-derailment bogie and derailment detection method based on bearing saddle positioning detection. The saddle is installed between the side frame and the axle box positioning device, and it also includes a derailment detection device installed on the inner side of the four bearing saddles; this patent mainly uses laser displacement meters to realize derailment early warning, but the alignment of laser displacement meters The requirements of the environment are high, and the change of the environment will affect the detection accuracy, which will greatly increase the false alarm rate of derailment
[0004] In summary, it is now necessary to design a rail vehicle anti-derailment control device and anti-departure control method to solve the problems in the prior art that derailment warning cannot be performed or the false alarm rate of early warning is high

The invention discloses an anti-off control device for a rail vehicle, which comprises: an anti-off device, which is seated on a track; an obstacle remover, which is fixed on the lower end of the anti-off device, and is located In the gap; wherein, the first ultrasonic ranging sensor and the second ultrasonic ranging sensor are arranged in the obstacle remover; the first ultrasonic ranging sensor is used to measure the distance a of the inner surface of the obstacle remover; the The second ultrasonic distance measuring sensor is used to measure the distance b between the obstacle remover and the bottom of the rail surface; it also includes a PLC control module, which is connected with the first ultrasonic distance measuring sensor and the second ultrasonic distance measuring sensor The sensors are electrically connected to receive the measurement data of the first ultrasonic distance measuring sensor and the second ultrasonic distance measuring sensor; in addition, the present invention also provides an anti-off control method. The real-time monitoring of the running status of rail vehicles is realized, which greatly reduces the false alarm rate of fault alarms; improves the safety of vehicles, and makes the anti-off control safer and more reliable.
Description
technical field [0001] The invention relates to the technical field of rail traffic, in particular to a rail vehicle anti-drop control device and a drop-off control method. Background technique [0002] The rail vehicle anti-drop control is related to the safe running of the vehicle. As a new type of urban rail car, the rail tram is gradually popularized and applied. It adopts the monorail steel wheel guiding mode, which is different from the traditional train guiding mode and the structure of the guiding device, resulting in the anti-drop control strategy. It is also different from the traditional traditional anti-off control, so it is very important to design a safe and reliable anti-off control strategy. [0003] Prior art CN105480250B discloses a derailment-proof bogie based on bearing saddle positioning detection and a derailment detection method. The derailment-proof bogie includes an axle box positioning device, a side frame, a bolster, a basic braking device and an a...
