Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only for explaining the utility model, and be not used in restriction the utility model.
The utility model has disclosed a kind of automobile component antitheft alarm system, referring to Fig. 1, it has: be installed on middle control circuit 1 in operator's compartment, at least one magnet-switch 3, the positive pole, anode power cord 4 of being drawn by automobile batteries 2 positive and negative electrodes be the antitheft loop of each magnet-switch and the series connection of middle control circuit respectively; Described magnet-switch is arranged on to be needed between antitheft automobile component and car body, and in the time that automobile component departs from car body, magnet-switch disconnects; Described middle control circuit comprises open circuit judge module, referring to Fig. 2, open circuit judge module is connected into closed antitheft loop by described positive and negative power lead and automobile batteries, each magnet-switch, sends open circuit signaling in the time that positive and negative power lead, automobile batteries or arbitrary magnet-switch disconnect; Warning power supply, in order to provide report to the police time required working power; Upper electrical switch, connects with described warning power supply, and arriving at open circuit signaling is to connect warning power supply to export described working power; Combined aural and visual alarm, connects working power, send sound and light alarm after electric.
Referring to Fig. 3, in use, automobile batteries, each magnet-switch, open circuit judge module are connected into closed antitheft loop by positive and negative power lead.Simultaneously referring to Fig. 1, one of them magnet-switch is installed in fuel tank 5 places, a magnet-switch is installed in spare tyre 6 places, in the time having people steal arbitrary parts wherein or cut short power lead, open circuit judge module judges that the disconnection of returning sends open circuit signaling, upper electrical switch is subject to drive closed, and combined aural and visual alarm obtains the electric sound and light alarm that sends.
The effect that combined aural and visual alarm plays and threatens robber, reminds car owner and the periphery masses.But when automobile component is stolen sometimes, car owner, or not the time of incident city, just can not stop combined aural and visual alarm, combined aural and visual alarm can become noise source and perplex resident around always.So a time delay module need to be set limit the warning duration of combined aural and visual alarm.Therefore in described in preferred embodiment control circuit also comprise one connect working power time delay module and be serially connected in working power and combined aural and visual alarm between halt switch, time delay module start timing after electric, meter disconnects to controlling halt switch after setting-up time.
After automobile component is stolen, automobile batteries stops to middle control circuit power supply, and combined aural and visual alarm required electric power is provided by the power supply of reporting to the police.For ensureing that warning power supply has sufficient electric weight, usually just needs monitoring alarm power supply.Therefore control circuit also comprises a low pressure alarming module that connects warning power supply in described in preferred embodiment.
Referring to Fig. 4, the judge module of opening a way in preferred embodiment comprises that one end connects the wire fuse FB1 of described positive power line, the other end of wire fuse connects one end of the first capacitor C 1 and the 3rd resistance R 3, the other end of the 3rd resistance connects the negative electrode of the second resistance R 2 and the second diode D2 and sends described open circuit signaling, and the other end of the first electric capacity, the second resistance is connected described negative power line ground connection with the negative electrode of the second diode.Described upper electrical switch adopts the 2nd PMOS pipe (PMOS2), and its gate pole connects described open circuit signaling, the positive pole of its power supply taking alarm (VBat) that drain, and its source electrode is exported described working power, the negative earth of warning power supply.In Fig. 4, interface P2 takes over control and steals loop, and in the time that antitheft loop disconnects, the current potential of R3 and R2 point of connection reduces, the PMOS2 conducting that is triggered, and the warning power supply (9V direct current (DC)) that interface P1 connects is sent described working power VDD by PMOS2.
Referring to Fig. 6, mainly comprise that at time delay module described in preferred embodiment model is the first counting chip (U2) of CD4060 and the second counting chip (U3) that model is CD4020, CD4060 is made up of 14 grades of binary string linage-counter positions, and CD4020 is 14 binary string linage-counters.Two input pins (the 10th pin and the 11st pin) of the first counting chip connect the crystal oscillator that frequency is 32.768Hz (Y1), the output pin (pulse of the 3rd pin output 2Hz) of the first counting chip connects the input end of the second NAND gate (U4B), the input end (the 10th pin) of output termination second counting chip of the second NAND gate, the mouth (the 3rd pin) of the second counting chip connects two input ends of the first NAND gate (U4A) and connects the gate pole of described halt switch (PMOS1), and the mouth of the first NAND gate connects another input end of the second NAND gate.U2 and U3, power on 1 hour can a high level of output after 20 points, make PMOS1 cut-off, combined aural and visual alarm stop alarm by this.P3, the P4 interface on Fig. 6 right side connect combined aural and visual alarm, because combined aural and visual alarm is ripe circuit, so do not draw in figure.
Referring to Fig. 5, mainly comprise a NMOS pipe (NMOS1) and the 2nd NMOS pipe (NMOS2) in the module of low pressure alarming described in preferred embodiment, the gate pole of the one NMOS pipe connects one end of the 8th resistance R 8 and the tenth resistance R 10, the power supply (VBat) of reporting to the police described in another termination of the 8th resistance, the drain electrode of the one NMOS pipe connects one end of the 12 resistance R 12 and the 9th resistance R 9, one end of another termination the 11 resistance of the 9th resistance and the gate pole of the 2nd NMOS pipe, the drain electrode of the 2nd NMOS pipe connects the other end of described wire fuse and the other end of the 12 resistance by LED light and the 7th resistance of series connection, the other end ground connection of the tenth resistance and the 11 resistance, the source ground of the one NMOS pipe and the 2nd NMOS pipe.
In the time that warning power supply has electricity, Vbat high potential, NMOS1 gate pole high potential, NMOS1 conducting, NMOS2 gate pole active potential, NMOS2 cut-off, LED lamp is not luminous.In figure, P5 is the interface that connects LED lamp.In the time that warning power supply does not have electricity, Vbat active potential, NMOS1 gate pole active potential, NMOS1 cut-off, NMOS2 gate pole high potential, NMOS2 conducting, LED lamp is luminous.Prompting user changes battery or charging.
In the time of normal replacing storage battery, fuel tank and spare tyre, need to make warning device quiet.Therefore at toggle switch S of the shelter of its shell device.Stir this switch, warning device is muted.Referring to Fig. 4, toggle switch S is serially connected between the drain electrode and warning positive source of upper electrical switch.
