Embodiment:
In Fig. 1,2,3, laser superelevation detecting device is comprised of laser transmitter 1 and laser receiver 2 two parts.Laser transmitter 1 is comprised of generating laser, modulated laser power supply and corresponding direction adjustment device; Laser receiver 2 is comprised of laser pickoff, photoelectric signal processor and corresponding supporting mechanism.Laser transmitter 1 will be launched directed intense laser beam, and good directionality, frequency is single, phase place is consistent, is that other light source is unrivaled.See that with I modulated laser light beam (single bundle or multi beam) forms warning line, adopts the mode of blocking warning that bridge, tunnel, urban viaduct etc. are carried out the superelevation protection.
Starting end at zone of protection arranges laser transmitter 1, and fixing with screw 8, and power lead is connected with power supply through connection jaws.Laser transmitter 1 is with the direct directive laser receiver 2 of its directed intense laser beam of launching.Convert the light signal that receives to the switching value signal at laser receiver 2 by photoelectric device, and process through Discr..When confirmation signal was normal, pilot lamp 5 was flame-out, keeps monitored state; And when light beam was interdicted, then signal was not normal, and pilot lamp 5 is lighted, simultaneously output alarm signal.Thereby realize to laser optical path the monitoring of system-wide journey of process.
Totally open, single beam laser superelevation detecting device can be used in monitoring point without the object that descends slowly and lightly, such as Fig. 3, when driving vehicle during through laser transmitter 1 and laser receiver 2, if vehicle superelevation not, the laser that laser transmitter 1 sends can not be blocked, the direct directive laser receiver 2 of laser beam, the signal of laser receiver 2 is normal, and pilot lamp 5 is flame-out, keep monitored state, not output alarm signal; And when driving vehicle process laser transmitter 1 and laser receiver 2, if vehicle super-high, light beam is interdicted, and then signal is not normal, and pilot lamp 5 is lighted, and exports simultaneously the alerting signal of superelevation.Thereby realize the superelevation monitoring to vehicle that laser optical path passes through.
For the object that prevents from descending slowly and lightly blocks laser generation false alarm, often having the place of the object that descends slowly and lightly to use double light beam laser superelevation detecting device, when only having beam of laser to be blocked, the signal of laser receiver 1 is normal, pilot lamp 5 is flame-out, keeps monitored state, not output alarm signal; When two bundle laser were blocked simultaneously, laser receiver 2 signals were not normal, and pilot lamp 5 is lighted, and exports simultaneously the alerting signal of superelevation.
