[specific embodiment]
In order better to understand technology contents of the present utility model, now with a kind of effect preferably embodiment illustrate, wherein Fig. 1 is the functional-block diagram of the utility model inductive automobile anti-theft system embodiment, and Fig. 2 is the signal inductor functional-block diagram of the utility model inductive automobile anti-theft system embodiment.The inductive automobile anti-theft system is hidden and is installed in the automotive interior space, wherein inductive automobile anti-theft system (following abbreviation system) comprising: anti theft host 201 is electrically connected with signal inductor 301,302,303,304 respectively with anti theft host 201 ..., vibration sensor 202, alarming horn 102, LED light 103, wireless communication module 101 and back battery 203.
Above-mentioned signal inductor 301,302,303,304 ... as shown in Figure 2, be made up of inductive head 501, magnetic test coil 502, amplifier 503, output circuit 504, the structure composition of signal inductor sees for details in the summary of the invention of the utility model specification sheets; In the present embodiment, the inductive head 501 of signal inductor is to adopt split unitized construction mode, more helps convenient the installation.It is suitable with transformer working principle to be wound with magnetic test coil 502 its principle of work on the inductive head 501, those skilled in the art all know, under moment that the DC current of passing through in detected lead is grown out of nothing or the moment from having to do not having or pulsatory current or other situation, magnetic test coil 502 can output have this principle of corresponding signal; Principle according to this, to the different operating state of vehicle distinct device the sign testing result signal of magnetic test coil output when the moment of bulb opening and closing and motor running (for example show as the variation of exporting number of pulses in the detection signal result) also inequality, its signal is sent into amplifier 503 amplify, convert this amplifying signal to output signal that micro controller system can discern by output circuit 504 then and offer main frame and handle.
Described signal inductor 301 is the working signals that are used to obtain central controlled lock, this signal inductor is that the supply line of central controlled lock or other control path related with the central controlled lock working phase are carried out non-contacting inductive pick-up, is the supply line of inductive pick-up central controlled lock in the present embodiment.
Described signal inductor 302 is the working signals that are used to obtain steering indicating light, this signal inductor is that the supply line of steering indicating light or other control path related with the steering indicating light working phase are carried out non-contacting inductive pick-up, is the supply line of inductive pick-up steering indicating light in the present embodiment.
Described signal inductor 303 is the mode of operations that are used to obtain the ignition lock circuit, this signal inductor be to ignition lock when ACC or the ON gear, the a certain equipment that carries out work for or other therewith the control path that is associated of equipment work carry out non-contacting inductive pick-up, be the supply line of inductive pick-up petrol feed pump motor in the present embodiment.
Described signal inductor 304 is to be used to obtain a working signal of limit circuit, this signal inductor is that the supply line of room light lamp (this illumination lamp ignition during car door opening) or other are carried out non-contacting inductive pick-up with the control path that the action of opening the door is associated, and is the supply line of inductive pick-up room light lamp in the present embodiment.
Workflow of the present utility model is such: in this embodiment, be to utilize former car remote controller to set antitheft to the utility model anti-theft system main frame and remove theft-proof.
Known, most of vehicle central controlled lock can glimmer with steering indicating light when locking or unblanking, the different manufacturers different automobile types lock, unblank at central controlled lock any action when taking place steering indicating light flicker number of times be not quite similar, but in any when action of locking or unblanking, the number of times of steering indicating light flicker generally all can be above 3 times.
Default is antitheft: during a certain actuating signal that signal inductor 301 collects that central controlled lock locks or unblank, do the legitimacy of further its actuating signal of judgement by signal inductor 302, when the sign testing result signal of signal inductor 302 output meets above-mentioned flicker condition, system enters the time-delay of removing anti-theft state and judges, if (do not open ignition lock to the ON gear) when signal inductor 303 has signal output in delay time, system enters anti-theft state.
System removes antitheft: antitheft principle is the same with setting, when signal inductor 301,302 collects and meets central controlled lock and lock or unblank a certain actuating signal of condition, system enters the time-delay of removing anti-theft state and judges, there are following two kinds of situations in sign testing result signal according to signal inductor 303 outputs in delay time: first kind of situation, petrol feed pump is the moment mode of operation, and system enters releasing anti-theft state synchronous signal inductor 301,302 and still is in the acquisition of signal mode of operation; Second kind of situation, petrol feed pump are continuous duty, and system enters the anti-theft state acquisition of signal work of danger signal inductor 301,302 simultaneously of removing.
Relation between ignition lock, driving engine, the petrol feed pump is that those of ordinary skill in the art knows, and no longer repeats here.
Under system is in anti-theft state, if vibration sensor 202 is triggered or signal inductor 304 output one signals (car door is opened), then anti theft host 201 will control alarming horn 102 send 103 flickers of alarm sound, LED light simultaneously anti theft host 201 also can export an alerting signal and give radio communication mold block assembly 101, by the phone of radio communication mold block assembly 101 timely contact car owner appointments, realize remote warning function.
Native system also comprises a back power supply 203 in addition, and back power supply 203 usefulness are wired to anti theft host 201, and the power supply of native system is provided provide when the power supply of native system is not connected with automobile storage battery.
