Abstract
The invention relates to a near-electricity alarm, belongs to the technical field of electric engineering safety cap alarm devices and especially relates to the near-electricity alarm capable of realizing grading alarming. The near-electricity alarm comprises an induction module, an A/D conversion module, a single-chip microcomputer, a power supply circuit, a wireless communication module, an LED light emitting module and a voice alarm module. The single-chip microcomputer is connected with the A/D conversion module, the power supply circuit, the wireless communication module, the LED light emitting module and the voice alarm module. When the near-electricity alarm approaches a high-voltage electric area, the induction module generates a corresponding induction current in a high-voltage alternating electromagnetic field, the induction current enters an input port of the single-chip microcomputer through the A/D conversion module and is compared with a set threshold in the single-chip microcomputer, a comparison result enters the voice and LED modules from an output port of the single-chip microcomputer, and corresponding grading alarming is carried out; in addition, GPS positioning communication with an external control room is carried out through the wireless communication module connected with the single-chip microcomputer. The safety of the personnel is substantially improved by the near-electricity alarm.
Description
Technical field
The present invention relates to a kind of alarming in short range of electric power device and belong to electrical engineering safety helmet alarm device technical field, especially a kind of can the alarming in short range of electric power device of classifying alarm.
Background technology
Usually need when working under environment under high pressure to wear alarming in short range of electric power device, common alarming in short range of electric power device adopts watch style, when wearing personnel mistakenly entering into charged region, alarming in short range of electric power device can again noncontact under conductive wire scenario, induced voltage sends continuous print alarm song, prompting personnel withdraw deathtrap in time, thus realizing the function of protection against electric shock and warning, reduce the generation of electric shock casualty accident.
Prior art there is also following deficiency: 1, only arranges single threshold, under the environment that electromagnetic interference is serious, and poor anti jamming capability, it is easy to false alarm; 2, alignment system is lacked, it is impossible to show up rapidly enforcement repairing and rescue.
Summary of the invention
The technique effect of the present invention can overcome drawbacks described above, it is provided that a kind of alarming in short range of electric power device, it greatly improves the safety of personnel.
For achieving the above object, the present invention adopts the following technical scheme that it includes induction module, A/D modular converter, single-chip microcomputer, power circuit, wireless communication module, LED light module and voice alarm module, single-chip microcomputer respectively with A/D modular converter, power circuit, wireless communication module, LED light module and voice alarm module electrical connection, when close to electrification in high voltage region, induction module produces corresponding faradic current in high-voltage alternating electromagnetic field, single-chip microcomputer input port is entered by A/D modular converter, in single-chip microcomputer with the threshold ratio set relatively, comparative result enters voice from single-chip microcomputer output port and LED module carries out corresponding classifying alarm, simultaneously by the wireless communication module with single-chip microcomputer connection, GPS positioning and communicating is carried out with external control indoor. .
Faradic current compares with current threshold successively in single-chip microcomputer, and when faradic current is less than one-level current threshold, personnel are distant outside safe distance from high-voltage power supply, can normal operation, alarming in short range of electric power device need not be reported to the police; When faradic current more than one-level current threshold less than two-level current threshold value time, alarming in short range of electric power device audio alert, simultaneously LED module sends green glow, and personnel can short stay; When faradic current more than two-level current threshold value less than tertiary current threshold value time, alarming in short range of electric power device audio alert, simultaneously LED module sends gold-tinted, and personnel can judge to take measures voluntarily; When faradic current exceedes tertiary current threshold value, audio alert LED module simultaneously sends HONGGUANG, and personnel need to leave at once to guarantee safety.

Detailed description of the invention
The alarming in short range of electric power device of the present invention, including induction module, A/D modular converter, single-chip microcomputer, power circuit, wireless communication module, LED light module and voice alarm module, single-chip microcomputer electrically connects with A/D modular converter, power circuit, wireless communication module, LED light module and voice alarm module respectively.
When close to electrification in high voltage region, induction module produces corresponding faradic current in high-voltage alternating electromagnetic field, enters single-chip microcomputer input port by A/D modular converter. In single-chip microcomputer with the threshold ratio set relatively, comparative result carries out the classifying alarm of correspondence from single-chip microcomputer output port entrance voice and LED module. Simultaneously by the wireless communication module with single-chip microcomputer connection, and external control indoor carry out GPS positioning and communicating. In electrification in high voltage region, the position of trapped personnel can be conveyed to control room by wireless communication module by alarming in short range of electric power device, it is simple to implement rapidly rescue; In high voltage fault region, it is possible to determine abort situation by wireless communication module, repair personnel is made to reach the spot the very first time.
Three current thresholds are had: one-level current threshold, two-level current threshold value and tertiary current threshold value in single-chip microcomputer.
Faradic current compares with current threshold successively in single-chip microcomputer, and when faradic current is less than one-level current threshold, personnel are distant outside safe distance from high-voltage power supply, can normal operation, alarming in short range of electric power device need not be reported to the police; When faradic current more than one-level current threshold less than two-level current threshold value time, alarming in short range of electric power device audio alert, simultaneously LED module sends green glow, and personnel can short stay; When faradic current more than two-level current threshold value less than tertiary current threshold value time, alarming in short range of electric power device audio alert, simultaneously LED module sends gold-tinted, and personnel can judge to take measures voluntarily; When faradic current exceedes tertiary current threshold value, audio alert LED module simultaneously sends HONGGUANG, and personnel need to leave at once to guarantee safety.
Power circuit is used for driving single-chip microcomputer.
