Description

Technical Field

[0001] The utility model relates to a safety distance alarm and protection device for rail vehicles, belonging to the technical field of safety distance alarm for rail vehicles. Background Art

[0002] The anti-collision alarm device for locomotives in mine roadways is composed of a signal transmitting component and a signal receiving component installed on both sides of the roadway. When a locomotive passes by, it gives out an audible and visual alarm. The vehicle safety distance alarm and prompt device includes a power supply module, a transceiver, a display device arranged at the rear of the vehicle, and a ranging probe. The transceiver, the display device, and the ranging probe are all connected to the power supply module. The display device and the ranging probe are connected to the transceiver through a communication module, which helps the driver of the following vehicle adjust the vehicle speed according to the provided information such as the vehicle distance, so as to reduce the occurrence of rear-end collisions.

[0003] However, the above devices have the following problems or disadvantages: (1) They cannot solve the safety distance protection alarm for rail vehicles; (2) There are no two side walls similar to those in roadways in the depot, so the signal receiver and signal transmitter cannot be installed. Technical difficulties: (1) The installation position and wiring of rail vehicles; the integration degree of rail vehicles is relatively high, and the equipment installation situation needs to be considered. (2) Since there are no side walls on both sides, the signal transmitter and receiver cannot be fixedly installed, and the signal source of the audible and visual alarm cannot be determined. Therefore, the installation positions of the signal transmitter and receiver must be reconsidered. Summary of the Utility Model
