The invention discloses a pedestrian safety protection independent laser device and method. The device comprises a plurality of linear laser devices and a laser transceiving sensor, wherein the linear laser devices emit linear laser to irradiate pedestrians to form a plurality of laser warning lines; the laser transceiving sensor emits a laser light curtain to cover the pedestrians, and senses whether pedestrians or vehicles exist on the path or not; when the laser transceiving sensor detects that the pedestrians pass through the path through laser light curtain scanning, the linear lasers emit linear laser; and when the laser transceiving sensor detects that the pedestrians disappear on the path through laser light curtain scanning, the laser transceiving sensor sends a closing signal to the linear lasers. Whether pedestrians or vehicles exist on a path (such as a zebra crossing) or not is sensed by the laser transceiving sensor, the linear laser devices emit linear laser when the pedestrians pass, and the linear laser devices are turned off until the pedestrians completely pass, so that the pedestrians are intelligently protected to pass safely in the whole process, energy consumption is reduced, meanwhile, damage of laser rays to people is reduced, and safety and reliability are higher.

    本发明公开了一种行人安全防护独立型激光装置及方法,该装置包括多个线状激光器和激光收发传感器,线状激光器发射线型激光以照射于行人身上形成多条激光警示线,激光收发传感器发射激光光幕覆盖于行人,同时感测路径上是否有行人或车辆,当激光收发传感器通过激光光幕扫描探测到有行人经过时,线状激光器发射线型激光,当激光收发传感器通过激光光幕扫描探测行人在路径消失后,发送关闭信号给线状激光器。通过激光收发传感器感测路径(如斑马线)上是否有行人或车辆,有行人通过时使线状激光器发射线型激光,直到行人完全通过后关闭,从而实现全程智能守护行人安全通行,节省能耗,同时减少激光线对人的损伤,更加安全可靠。
