Utility model content
The purpose of this utility model is exactly provide a kind of in power construction operation process to solve above-mentioned deficiency; the personal safety of operating personnel in the construction of energy available protecting; prevent electric system short circuit over the ground, ensure that transmission line of electricity that electric power safety runs is anti-outer broken with close to early warning system.
The technical solution that the utility model adopts to solve the problems of the technologies described above is as follows:
Transmission line of electricity is anti-outer broken with close to early warning system, native system mainly includes detection agency, cpu system, wireless transmitter module and alarm mechanism, described detection agency is primarily of electric field detecting device and distance detector composition, described alarm mechanism is primarily of wireless receiving module, STM master control borad, voice guard and LCDs composition, described electric field detecting device is powered by power module, detect whether there is electrified body around by its Three-Dimensional Electric Field probe, when electrified body being detected, this electrified body electric field signal is gathered, be converted into voltage signal, through protection circuit, amplifying circuit, filtering circuit and comparator circuit, AD acquisition function finally by single-chip microcomputer obtains original signal, alarm mechanism is sent to by cpu system and wireless transmitter module, described distance detector is powered by power module, the ultrasonic signal of short pulse duration is launched towards periphery by its ultrasonic listening module, calculate the distance of ultrasonic listening module and barrier when running into barrier, this signal is sent to alarm mechanism by cpu system and wireless transmitter module, described alarm mechanism is powered by power module, by the signal that its wireless receiving module reception electric field detecting device and distance detector send over, after being analyzed by STM master control borad, if the time in of around there is electrified body and be less than the safe distance of this electrified body with ultrasonic listening module distance, alarm mechanism will send acousto-optic early warning by voice guard, be shown the real-time distance whether having charged object and electrified body and ultrasonic listening intermodule by LCD screen.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: whether have electrified body around the heavy mechanical equipments such as monitoring crane that 1, can be real-time and engineering truck; Heavy mechanical equipment and the distances between engineering truck and ultra-high-tension power transmission line such as monitoring crane that 2, can be real-time; 3, totally digital circuit controls, and avoids the error because the factor such as device aging, temperature causes; 4, device structure is simple, dependable performance and each to measure item accurate; 5, adopt wireless communication technique, be easily installed in alarm mechanism telecommunication in detection agency on the heavy mechanical equipments such as crane and engineering truck and pilothouse, without the need to wiring, installing simply; Whether have around the heavy mechanical equipments such as 6, Information Monitoring is shown by LCD screen in real time, the real-time known crane of operating personnel and engineering truck electrified body and and electrified body between distance.
Accompanying drawing explanation
Fig. 1 is that transmission line of electricity of the present utility model prevents the outer broken theory diagram close to early warning system;
Fig. 2 is the internal logic block diagram of distance detector of the present utility model;
Fig. 3 is the internal logic block diagram of electric field detector of the present utility model.
Embodiment
By Fig. 1, shown in Fig. 2 and Fig. 3, transmission line of electricity is anti-outer broken with close to early warning system, native system mainly includes detection agency, cpu system, wireless transmitter module and alarm mechanism, described detection agency is primarily of electric field detecting device and distance detector composition, described alarm mechanism is primarily of wireless receiving module, STM master control borad, voice guard and LCDs composition, described electric field detecting device is powered by power module, detect whether there is electrified body around by its Three-Dimensional Electric Field probe, when electrified body being detected, this electrified body electric field signal is gathered, be converted into voltage signal, through protection circuit, amplifying circuit, filtering circuit and comparator circuit, AD acquisition function finally by single-chip microcomputer obtains original signal, alarm mechanism is sent to by cpu system and wireless transmitter module, described distance detector is powered by power module, the ultrasonic signal of short pulse duration is launched towards periphery by its ultrasonic listening module, calculate the distance of ultrasonic listening module and barrier when running into barrier, this signal is sent to alarm mechanism by cpu system and wireless transmitter module, described alarm mechanism is powered by power module, by the signal that its wireless receiving module reception electric field detecting device and distance detector send over, after being analyzed by STM master control borad, if the time in of around there is electrified body and be less than the safe distance of this electrified body with ultrasonic listening module distance, alarm mechanism will send acousto-optic early warning by voice guard, the real-time distance whether having charged object and electrified body and ultrasonic listening intermodule is shown by LCD screen, reach the object of available protecting operating personnel personal safety, also effectively prevent simultaneously and occur the electric system serious accident that causes such as short circuit over the ground.
The various module occurred in above-mentioned embodiment and the concrete composition of device and structure are prior art, and the those skilled in the art of the art all obtain, at this without the need to describing in detail in self-control or can commercially buy.
The utility model passes through electric field detecting device and the distance detector of detection agency, effectively can detect the ambient conditions of operator in real time, prevent the heavy mechanical equipment such as crane and engineering truck operating personnel when operation from getting an electric shock when high voltage power transmission near circuitry works, effectively prevent the electric system serious accident such as short circuit over the ground that may occur.When detection agency of the present invention is near ultra-high-tension power transmission line, system can send sound and light alarm, reminds operating personnel to answer shut-down operation, takes care, finally protect the safety of operating personnel, and avoids the harm of the electric system that may therefore cause short circuit over the ground.
