The multi-beam laser of anti-outside destroy hi-line detects prior-warning device
technical field:
The utility model relates to a kind of more line detector, and particularly a kind of multi-beam laser of anti-outside destroy hi-line detects prior-warning device.
background technology:
Transmission line of electricity is the artery of electric system, and its running status directly determines safety and the benefit of electric system.But power circuit often suffers outside destroy in recent years, cause line tripping, cause the probability of large area blackout in ascendant trend rapidly, cause our very big attention.Safeguard transmission line of electricity safety, ensure that the stable of electric power has great significance for reply national development and people's lives.The form of transmission line of electricity outside destroy is numerous, has construction violating the regulations, high-stem plant and the ultrahigh equipment such as tower crane, vehicle to pass through overhead transmission line and directly causes wire cut-out etc.Meanwhile, be there is the shortcoming of cycle length by artificial line walking, make the prevention effect of outside destroy unsatisfactory, this brings serious threat to the safety and stablization of electric system.At present, various places operation power administrative authority is according to different situations, take the safe precaution measure based on video frequency graphic monitoring, but, because needs carry out Real Time Observation by personnel on backstage, cannot ensure for a long time effectively to monitor position, and, by early warning system that is infrared, microwave sounding, because detection range is near, rate of false alarm is high.As publication number is: CN203812350U patent discloses the anti-outside destroy remote-control device of a kind of laser class, what this device adopted is single beam laser detection, if there is flying object to interdict laser, false alarm phenomenon will occur.
summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of can round-the-clockly monitor electric power pylon ambient conditions, note abnormalities and alarm, false alarm phenomenon can not be there is, transmission line of electricity safety can be guaranteed, ensure that the multi-beam laser of the anti-outside destroy hi-line that electrical power stabilization is run detects prior-warning device.
A kind of multi-beam laser of anti-outside destroy hi-line detects prior-warning device, comprise laser transmitter, laser receiver, alarm host machine, phonetic alarm, visual alarm, solar power supply apparatus, high-definition camera, during work laser transmitter and laser receiver staggered relatively, laser receiver is connected with alarm host machine and solar power supply apparatus by cable, and alarm host machine is connected with phonetic alarm, visual alarm and solar power supply apparatus respectively by cable.Laser transmitter is at least provided with two generating lasers.Laser receiver is at least provided with two laser pickoffs, its circuit connects in parallel, the laser only having all laser pickoffs not receive opposite generating laser to send, pilot lamp just can be bright, and alarm host machine will send warning message to phonetic alarm and visual alarm.
Solar power supply apparatus comprises solar panels and lithium battery, lightweight, long service life, is easy to install.
The beneficial effects of the utility model are, laser characteristics is excellent, and quality is higher, and detection range is far away, greatly reduces the false alarm that climatic environment produces.Installation and Debugging are easy, stable, serviceable life, flexible configuration of setting up defences, and strick precaution precision is high, and laser monochromaticity is strong, and good directionality, each other without crosstalk, can meet the security protection requirement of higher level.Wide adaptability, versatility is good, and strong interference immunity is noiseless to miscellaneous equipment, also has that cost is low, construction volume is few.Round-the-clock electric power pylon ambient conditions can be monitored, note abnormalities and alarm, false alarm phenomenon can not occur, transmission line of electricity safety can be guaranteed, ensure that electrical power stabilization is run.
accompanying drawing illustrates:
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the connection diagram of each parts of the utility model.
In figure: 1 laser transmitter, 2 laser receivers, 3 alarm host machine, 4 phonetic alarms, 5 visual alarms, 6 solar power supply apparatus, 7 high-definition cameras.
embodiment:
As shown in Figure 1, a kind of multi-beam laser of anti-outside destroy hi-line detects prior-warning device, comprise laser transmitter (1), laser receiver (2), alarm host machine (3), phonetic alarm (4), visual alarm (5), solar power supply apparatus (6), high-definition camera (7), during work laser transmitter (1) and laser receiver (2) staggered relatively, laser receiver (2) is connected with alarm host machine (3) and solar power supply apparatus (6) by cable, alarm host machine (3) by cable respectively with phonetic alarm (4), visual alarm (5) and solar power supply apparatus (6) are connected.Described laser transmitter (1) is at least provided with two generating lasers.Described laser receiver (2) is at least provided with two laser pickoffs, its circuit connects in parallel, the laser only having all laser pickoffs not receive opposite generating laser to send, pilot lamp just can be bright, and alarm host machine (3) will send warning message to phonetic alarm (4) and visual alarm (5).Described solar power supply apparatus (6) comprises solar panels and lithium battery, lightweight, long service life, is easy to install.
Principle of work: laser transmitter (1) is set on a shaft tower of adjacent hi-line, another shaft tower arranges laser receiver (2), the direct directive receiver (2) of directed intense laser beam that transmitter (1) is launched.Convert the light signal received to on-off model at receiver (2) by photoelectric signal processor, when confirmation signal is normal or segment beam is interdicted, pilot lamp all stops working, and keeps monitored state; And when light beam is all by blocking, then signal is not normal, and pilot lamp is lighted simultaneously, and alarm host machine (3) will send warning message to high-definition camera (7) phonetic alarm (4) and visual alarm (5), high-definition camera (7) is opened automatically simultaneously, can monitor on-the-spot real-time condition.Thus realize to laser optical path the monitoring of system-wide journey of process.
