Abstract
The utility model relates to an anti-theft and anti-hijack alarm for an automobile, comprising an anti-theft and anti-hijack alarm and a high voltage ultra-low frequency guarding device two suites. If robbers open the automobile door (cover), break the glass, touch the seats, start the igniter for fire, shorting or dismounting the battery, the utility model can dispatch speech calling and acousto-optic signals, cut off the ignition circuits and create pause high voltage and ultra-low frequency noise for anti-theft and self-defense, and the utility model also has the functions of alarm timing and alarm status automatic setting. The utility model is suitable for various automobiles and can also be used for warning other important facilities.
Description
The utility model belongs to a kind of guard and alarm control setup, the anti-theft alarm controller of holding of particularly a kind of automobile self-defence formula.
The car equipment burglar alarm is the effective means of the criminal of preventing robber crime.The Different Kinds of Automobiles burglar alarm adopts the switching regulator sensor mostly both at home and abroad at present, it is simple in structure, rate of false alarm is little, shortcoming is not reset after the warning if switch sensor is triggered, then annunciator can not recover warning automatically, and this type of sensor is committed a crime into the car and just warning can't be set for breaking glass in addition.Because annunciator relies on automobile storage battery power supply is provided, as long as the robber hatches a little scheme, storage battery is removed (opening circuit) or short circuit, annunciator has just lost effectiveness.The defective of general burglar alarm maximum is that warning function is only arranged, and the not anti-self-defense capability of stealing.Defend oneself though the utilization that has continues the high potential of generation volts up to ten thousand, cause easily and defend excessively and accidentally homicide, if the robber takes the failure-free insulation measures, the high pressure defence will be ineffective.
The purpose of this utility model provides a kind of anti-theft alarm, anti-automobile self-defence formula antitheft alarm system of defending oneself, preventing abduction and tamper-proof function of stealing of having both, it is applicable to various automobiles, also can be used for the warning of other critical facilitys, reduce robber's opportunity as far as possible, ensure country, collective and individual's property safety effectively.
The utility model is made up of anti-theft annunciator and high pressure ulf defence device two external members of holding, and anti-theftly holds that annunciator comprises feed circuit ［ 1 ］, warning switch circuit ［ 2 ］, carries out warning circuit ［ 3 ］, timer ［ 4 ］, carries out control circuit ［ 5 ］, prevents kidnapping switch circuit ［ 6 ］, language call circuit ［ 7 ］, pause switch circuit ［ 8 ］, alarm indicator ［ 9 ］; High pressure ulf defence device comprises the ulf defence system of high pressure defence system, ultralow-frequency oscillator ［ 13 ］ and ulf actuator ［ 14 ］ composition that feed circuit ［ 10 ］, blocking oscillatot ［ 11 ］ and high-voltage inverter ［ 12 ］ are formed.Its two external member adopts 12V automobile storage battery and backup power parallel operation respectively.
