The invention discloses a rail vehicle early warning braking device for a test line, which comprises an infrared emission unit arranged beside the line, and an infrared receiving unit, a control unit and an execution unit arranged on a vehicle, and the infrared receiving unit and the execution unit are respectively communicated with the control unit; the number of the infrared emission units is multiple, and the multiple infrared emission units are arranged at intervals along a line. The frequencies or duty ratios of infrared signals emitted by the infrared emission units are different; the control unit is used for controlling the execution unit to execute different actions according to different frequencies or duty ratios of the received signals, and the actions comprise alarming and emergency braking and further comprise at least one of load shedding, punishment braking and traction blocking. Due to the adoption of the technical scheme, compared with the prior art, the current position of the vehicle can be obtained by identifying the characteristics of the infrared signal, and the corresponding action is executed according to the current position, so that the safety early warning requirement of a test line is met.
本发明公开了一种用于试验线的轨道车辆预警制动装置,包括布置在线路旁的红外发射单元以及布置在车辆上的红外接收单元、控制单元和执行单元,红外接收单元和执行单元分别与控制单元通信;所述红外发射单元设有多个,多个所述红外发射单元沿线路间隔布置;各红外发射单元所发出的红外信号的频率或占空比不同;所述控制单元用于根据接收信号的频率或占空比的不同控制所述执行单元执行不同的动作,所述动作包括报警和紧急制动,还包括减载、惩罚制动和牵引封锁中的至少一种。由于采用了上述技术方案,与现有技术相比,本发明通过识别该红外信号的特征即可获取车辆的当前位置,并据此执行相对应的动作,从而满足试验线路安全预警需求。
