Abstract
The utility model relates to an anti-theft device of automobile with a damage-proof host machine, which comprises a host machine, an alarming horn and an automobile ignition control unit. The utility model is characterized in that the alarming horn is a purpose-made alarming horn provided with a controller, a horn controller (24) is composed of an NPN transistor (20) and a PNP transistor (19), and the horn controller is arranged below a front cover of automobile and is directly connected with a battery jar (9) of automobile. When the host machine is damaged, an ignition coil of automobile can be cut off, so that the automobile can not be started, and send outs alarming sound to threaten and remind people. Compared with ordinary anti-theft alarm devices of automobile, the utility model is distinctly more advanced.
Description
The utility model relates to vehicle electric field, particularly is the car alarm that a kind of main frame is not afraid of destruction.
Popular various car alarms are gone up by society at present all a common drawback, in case promptly main frame is destroyed, the function of its anti-theft alarm has also disappeared immediately.Thereby the Car Burglar Alarm main frame is the main object that the robber destroys.
The purpose of this utility model is: provide a kind of under the situation that main frame is damaged, and the one, can cut off automotive ignition and now enclose car can't be started, the 2nd, still can send chimes of doom and intimidate the car alarm of noting with reminds people.
Described main frame is not afraid of the car alarm of destruction, comprise main frame, alarming horn, Automobile Igniting Control unit each several part, it is characterized in that: described alarming horn is a kind of special alarming horn of tape controller, the horn controller (24) that one end of this special alarming horn (12) is formed via NPN aerotron (20) and PNP aerotron (19) links to each other with the positive pole of automobile storage battery (9), and the signal input part of this horn controller links to each other through the loudspeaker control signal output ends of alarm control line (11) with main frame (15); The control signal input line of Automobile Igniting Control unit (25) links to each other with the ignition control signal delivery port of main frame (15) through the base stage of this unit aerotron (23), be connected to relay line bag (22) on the collecting electrode of aerotron (23), the other end of relay line bag (22) links to each other with the positive pole of automobile storage battery (9), and the open contact of this relay is serially connected on automobile switch (7) and the automobile ignition coil pri loop.Described special alarming horn (12) is placed in below the automobile protecgulum, and directly is connected on the automobile storage battery (9).
Below in conjunction with accompanying drawing 1 its principle of work is illustrated.When main frame (15) was in cloth police state, alarm control line (11) was in active potential, and special alarming horn (12) is in power failure state, can not report to the police.The elementary break-make control line of high-tension coil (13), (14) are in off-state simultaneously, and closed automobile switch (7) can't make high-tension coil (8) charged, thereby automobile can not start.If meet alarm factors, then alarm control line (11) loses active potential, special alarming horn (12) obtains 12V voltage, send strong chimes of doom, (13), (14) line are kept off-state simultaneously, and closed automobile switch (7) is of no avail, and high-tension coil (8) still can not obtain, automobile can't start, so realize anti-theft alarm function.
Arbitrary or two whiles are pulled down in destroyed or power lead (2), (3) when main frame (15), and then alarm control line (11) loses active potential (no current potential), and special alarming horn obtains the 12V electricity naturally, sends strong chimes of doom; Simultaneously, (13), (14) line continue to keep off-state, and high-tension coil can't be worked.Therefore, the effect of anti-theft alarm still can be played by under the situation of pulling down in destroyed and power lead (2), (3) at main frame.When main frame is in when disappearing alert state, (11) line often is an active potential, and loudspeaker can not reported to the police, and (13), (14) line normal open can normally start automobile simultaneously.This is described utility model special feature.
Like this burglar alarm under the situation that main frame is damaged, can cut off automotive ignition and now enclose car can't be started, and still can send chimes of doom and intimidate with reminds people and note, obviously than general-utility car burglar alarm advanced person.Wherein, the special alarming horn of tape controller is the elite for design.
Fig. 1 is the utility model schematic circuit diagram.(2) are power cathode (bonding) lead-in wire among the figure, (3) be positive source (12V) lead-in wire, (7) be the automobile switch, (8) be automobile ignition coil, (11) be the alarm control line, (12) be special alarming horn, (13), (14) are the elementary break-make control line of high-tension coil, and (15) are main frame.
Fig. 2 implements circuit diagram for the utility model.(2) are power cathode (bonding) lead-in wire among the figure, (3) be positive source (12V) lead-in wire, (5) be alarming horn, (7) be the automobile switch, (8) be automobile ignition coil, (9) be automobile storage battery (storage battery), (11) are the alarm control line, and (12) are special alarming horn, (13), (14) be the elementary break-make control line of high-tension coil, (15) be main frame, (16) are CPU, (17), (18), (19), (20), (23) be aerotron, (21) be relay normally open contact, (22) be relay line bag, (24) are horn controller, and (25) are ignition control unit.
In conjunction with implementing circuit diagram 2, the utility model implementation process is narrated.When main frame (15) is in the alert state of cloth, CPU (16) gives aerotron (17) base stage one active potential, aerotron (17) ends, (18) conducting, alarm control line (11) obtains active potential, thereby aerotron (20) ends, and then aerotron (19) also ends, alarming horn (5) can not get positive potential, does not report to the police; CPU (16) also is a negative voltage to aerotron (23) base stage simultaneously, aerotron (23) ends, relay line bag (22) can't be connected, relay normally open contact (21) disconnects, the automobile switch (7) that closes also can't make the first utmost point of automobile ignition coil (8) obtain electricity, and secondly utmost point can not produce the high voltage startup driving engine.This state is if meet alarm factors, and then CPU (16) gives aerotron (17) base stage one high potential, aerotron (17) conducting, (18) end, alarm control line (11) loses active potential, then aerotron (20), (19) conducting in succession, alarming horn (5) obtains the 12V positive voltage, thereby reports to the police.CPU this moment (16) still gives aerotron (23) base stage negative potential, and automobile still can not start as a result, thereby has realized the basic function of anti-theft alarm.
If main frame (15) is destroyed or power lead (2), (3) in arbitrary or two whiles pulled down, obviously alarm control line (11) loses active potential (or not having current potential), aerotron (20), (19) conducting, alarming horn (5) obtain the 12V positive voltage and produce warning.Same this kind situation is ended because of aerotron (23), and relay line bag (22) can't be connected, and relay normally open contact (21) can not be closed, and then automobile can not start, and has realized the function of anti-theft alarm.
