In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with drawings and embodiments pairThe utility model is described in further detail.
Referring to Fig. 1, the nearly electric prior-warning device structural representation of a kind of high-voltage line providing for the utility model embodiment.
The prior-warning device that the present embodiment provides comprises information acquisition device, and wherein information acquisition device comprises that electric field signal detects sensingDevice 1 and displacement transducer 2, it is current after certain displacement that electric field signal detecting sensor 1 is used for detecting workmenThe electric-field intensity of position, the electric field signal detecting sensor 1 that the present embodiment provides is power frequency electric field signal detection sensor 1In rod-pulling type Straight Wire Antenna, but it should not serve as the restriction of the utility model protection domain, art technology peopleMember can select other sensors according to actual conditions, and it all should fall into protection domain of the present utility model.
And displacement transducer 2 is mainly used to detect workmen's shift length, in the present embodiment, displacement transducer 2 is selectedMiniature acceleration device, but it should not serve as the restriction of the utility model protection domain, and those skilled in the art can rootSelect other displacement transducer 2 according to actual conditions, it all should fall into protection domain of the present utility model.
The prior-warning device that the present embodiment provides also comprises calculator 3 and controller 8, wherein information acquisition device and calculator 3Connect, calculator 3 is connected with controller 8, and information acquisition device is collecting the electricity of current location after displacement information and displacementAfter field intensity, the displacement information recording and electric-field intensity are delivered in calculator 3, calculator 3 is by calculating and comparing, thus the high-voltage line electric pressure of definite workmen's environment of living in, and the actual measurement electric-field intensity and the peace that relatively recordFull electric-field intensity, if actual measurement electric-field intensity is more than or equal to safety electric field intensity, illustrates that workmen enters danger so, there is the danger being electrically shocked in region. Now calculator 3 is by defeated the comparing result of actual measurement electric-field intensity and safety electric field intensityEnter to controller 8, judge whether to send early warning information by controller 8. Controller 8 is calculating after result, by electric fieldThe actual measurement electric-field intensity that signal detection sensor 1 detects, shift length and the calculator that displacement transducer 2 detects3 results that calculate are all presented on output and display 6.
In the time that actual measurement electric-field intensity is more than or equal to safety electric field intensity, controller 8 is controlled alarm 4 and is reported to the police, reportAlert device 4 is connected with controller 8, and whether controller 8 reports to the police for controlling alarm 4. Alarm 4 is set to acousto-optic reportAlert device 4, audible-visual annunciator 4 can be sounded and light alarm signal simultaneously, reminds workmen in deathtrap,Inform that workmen releases deathtrap in time, ensure workmen's safety. The sound that audible-visual annunciator 4 provides and lightLine warning is the reliability in order to improve system, prevents that workman may ignore some warning letter under complex environment conditionBreath, ensures that workman just can know in time and return at the beginning of can entering deathtrap to the full extent.
In addition, controller 8, in the time receiving judged result, sends to wireless communicator 5 by early warning signal simultaneously, passes throughEarly warning information is sent to control centre by wireless communicator 5, and wherein early warning information comprises actual measurement electric-field intensity and workmenHigh-voltage line electric pressure of living in, wireless communicator 5, in the time that early warning information is sent to control centre, is exported and display 6On demonstrate accordingly actual measurement electric-field intensity and workmen's high-voltage line electric pressure of living in. Control centre receives these lettersAfter breath, store on the one hand, will help on the other hand control centre to understand in time workmen's environment of living in and workMake state, in the time that workmen is in the hole, control centre also can notify workmen away from deathtrap in timeOr send rescue personnel to carry out rescue work.
The prior-warning device that the present embodiment provides also comprises alignment sensor 9 and attitude transducer 10, alignment sensor 9 and appearanceState sensor 10 is electrically connected with controller 8 respectively, and wherein alignment sensor 9 is for Real-time Obtaining workmen's geographical positionPut, attitude transducer 10 is for Real-time Obtaining workmen's attitude. When control centre receives, controller 8 transmission comesWhen warning message, controller 8 can send workmen's geographical position to control centre simultaneously, and control centre can basisRescue action is implemented in workmen position, and control centre also can know environmental geography described in workmen in real time in additionPositional information and duty, and record diverse geographic location electric-field intensity information. Attitude transducer 10 will get constructionPersonnel's attitude information is sent to controller 8, and attitude information is sent to control centre by controller 8, and attitude herein passesWhether sensor 10 is main detects workmen and falls down, controller 8 receive confirm after attitude information workmen whether inPrecarious position, for example, the workmen's that controller 8 receives attitude in falling down state, illustrates constructor for a long timeMember has now run into unsafe condition, sends alarm signal, and attitude early warning signal is sent in control with Time Controller 8The heart, early warning signal reminds staff around to succour in time workmen, and control centre also can send personnel in time simultaneouslyLaunch rescue work according to the geographical location information receiving.
The warning device providing in the present embodiment also comprises charger and power circuit converter, and charger is used to early warning dressPut direct current is provided, power circuit converter is used for 220V alternating current to be converted to direct current, and charger is charged.
