Abstract
A power safety distance voice prompt system can judge a distance from a high-voltage electrified body by detecting the intensity of an electromagnetic field by adopting the distribution of an electromagnetic field near a high-voltage power line or the high-voltage electrified body; and the high-voltage electromagnetic fields with different levels have the different electromagnetic intensities, so that different levels of safety distances can be judged, and the safety production of an operator can be prompted by playing voice. The system is not influenced by surrounding environmental temperature; and the safety distance near the high-voltage power line or the high-voltage electrified body can be judged conveniently, exactly and fast; and the operation of a user is quite simple.
Description
Technical field
The utility model relates to a kind of electric power safety system, and what be specifically related to is that a kind of electric power safety is apart from speech prompting system.
Background technology
Around high-voltage power line and high-voltage charged body, be easy to take place the dead accident of person electric shock, this danger-restricted area is being perplexed the operation of electric power system always and is being threatened power consumer one line worker; At present, a kind of language alarm that can be used for electric power system is arranged, it adopts the infrared induction principle, mainly eliminated cooperation filter window such as element is made up of the germanium lead titanate ceramics of high Seebeck coefficient and lithium tantalate, sulfuric acid swill, can detect the infrared energy variation that object radiates out with the noncontact form, and it is become signal of telecommunication output, this device is because relatively more responsive to variation of temperature, when in very big environment of winter, the summer temperature difference, the reliability of its work just is difficult to hold.Therefore, under high-voltage fence, also there is not a kind of very good security alerting system available at present.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provide a kind of electric power safety apart from speech prompting system, utilization has the distribution of electromagnetic field intensity near high-voltage power line or high-voltage charged body, intensity by detection of electromagnetic fields just can the judging distance high-voltage charged body distance, the high-voltage electromagnetic field intensity difference of different brackets, the safe distance of different brackets be can judge and speech play, prompting operation person's safety in production passed through.
The utility model is to be achieved through the following technical solutions: electric power safety comprises electromagnetic field intensity sensor unit, single-chip microcomputer processing unit, power amplifier unit, power supply unit and control button unit apart from speech prompting system;
The electromagnetic field intensity sensor unit is to adopt field effect transistor to sense the voltage of alternation;
The single-chip microcomputer processing unit is to adopt mould/number conversion circuit, monolithic intelligent computer system and customized voice chip to form;
Power supply unit is to adopt 4 3A batteries, and the power supply of 6V/500mAH is powered to native system;
The control button unit is the selective or indication of high pressure that is provided with different brackets;
The utility model compared with prior art, beneficial effect is, utilization has the distribution of electromagnetic field intensity near high-voltage power line or high-voltage charged body, intensity by detection of electromagnetic fields just can the judging distance high-voltage charged body distance, the high-voltage electromagnetic field intensity difference of different brackets, can judge the safe distance of different brackets and pass through speech play, prompting operation person's safety in production, the utility model system is not subjected to the influence of ambient temperature, can be convenient, accurately, judge near the safe distance of high-tension electricity transmission line or high-voltage charged body quickly, and the user operates very simple.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail;
Fig. 1 is a flow chart of the present utility model;
Fig. 2 is an example illustration intention of the present utility model.
Embodiment
As shown in Figure 1, electric power safety comprises electromagnetic field intensity sensor unit, single-chip microcomputer processing unit, power amplifier unit, power supply unit and control button unit apart from speech prompting system;
The electromagnetic field intensity sensor unit is to adopt field effect transistor to sense the voltage of alternation;
The single-chip microcomputer processing unit is to adopt mould/number conversion circuit, monolithic intelligent computer system and customized voice chip to form;
High pressure such as 10KV, 35KV, 110KV and 220KV because of different brackets, its electromagnetic field distribution is different, induce the voltage of alternation by the alternating electromagnetic intensity sensor, and the conversion of the mould/number conversion circuit by the STC12C2052AD single-chip microcomputer, and the calculating judgment processing by monolithic intelligent computer system, when magnetic field intensity during greater than the numerical value of regulation, system just triggers the content that stores in the customized voice chip, drives loudspeaker by power amplifier and emits voice.
As shown in Figure 2, be specific embodiment of the utility model:
In the present embodiment, adopt 4 3A batteries, the power supply of 6V/500mAH is powered to native system, and at start quiescent current≤2mA (indicator light demonstration), operating current≤100mA, the shutdown electric current is mA, and in default: 10KV≤2 meter, 35KV≤2.5 meter, 110KV≤3.5 meter, 220KV≤4 meter, more than all be per 0.5 meter/one grade setting;
Its use step of phonetic alarm that applies to native system is as follows:
1, open alarm mains switch 1, the indication of native system voice " is welcome electrification safe distance phonetic alarm ", and the 10KV indicator light on " current working voltage is 10KV " while scope of application indicator light interface 2 lights;
2, if need of work changes, press the working range selector switch, whenever press once, indicator light cycle changes once, is indicated to the current application voltage range, and equipment stores automatically, needn't reset after the shutdown;
3, phonetic alarm during switch yard, plays out voice suggestion from loudspeaker 3 in the staff enters certain voltage transformer station:
(1), you have entered 2 meters of 10KV safe distances, please don't be close;
(2), you have entered 2.5 meters of 35KV safe distances, please don't be close;
(3), you have entered 3.5 meters of 110KV safe distances, please don't be close;
(4), you have entered 4 meters of 220KV safe distances, please don't be close;
4, finish using, ask powered-down.
Above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, as the technical solution of the utility model being made amendment or being equal to replacement, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
