摘要:
悬挂式轨道交通系统巡检车主动安全系统运用安全激光扫描仪和速度控制模块，能够测得距巡检车1.5 m以内的障碍物，并发出警报提醒驾驶员减速。该系统在1.2 m以内测到障碍物即向PLC(可编程逻辑控制器)发出危险信号，并自动控制电机制动。仿真结果表明，巡检车正常行驶过程中，遇到突发状况时，经过大约0.34 s，滑行0.8 m即可停稳。在中车青岛四方机车车辆有限公司悬挂式单轨试验线上进行现场测试时，该系统顺利通过了安全测试，验证了该主动安全系统的准确性和可靠性。巡检车主动安全系统能够有效避免事故发生，符合巡检车安全运营要求。
Abstracts:
By using the safety laser scanner and the speed control module, the active safety system installed on the suspended rail transit inspection vehicle can detect obstacles within 1.5 m of the inspection vehicle and alert the driver to decelerate. If the obstacle is within 1.2 m, the system will send out a danger signal to the PLC (programmable logic controller) and automatically control the motor braking. A simulation result shows that in case of unexpected conditions while in normal patrol, the vehicle can stop after about 0.34 seconds and glide only 0.8 m. The system has passed safety test smoothly when tested on the hanging monorail experimental line of Qingdao Sifang Locomotive and Vehicle Co., Ltd., the result verifies the accuracy and reliability of the active safety system. Since the system can avoid possible accidents effectively, it meets the requirements of safe operation for patrol vehicles.
