The specific embodiment

As Fig. 1,2 guard against theft oil monitoring fuel-quantity transducer, comprise by bearing 1, data pipe 4, magnetic float 5, fuel tank oil inlet 8, oil return pipe 3, circuit controller 9, data pipe 4 is connected on bearing, magnetic float 5 moving up and down is enclosed within on data pipe 4, fuel tank oil inlet 8, oil return pipe 3 connect on bearing, and fuel tank oil inlet 8, oil return pipe 3 communicate with bearing oil out port, bearing oil return interface by the oil circuit of bearing inside respectively; The head of fuel tank oil inlet is connected with filtering net 7 by plug 6, and in the direct pedestal mounted chamber of circuit controller 9, circuit controller 9 is drawn connection terminal 2.

As shown in Figure 3, the core of circuit controller is microprocessor, and the data pipe shown in Fig. 1, magnetic float form fuel-quantity transducer, draw ignition lock and power interface on microprocessor; A control port of microprocessor is connected with transistor switching circuit, to fuel level sensor, provides detectable voltage signals; Microprocessor is connected with outside infrared ray sensing module, also draws alarm controller interface on microprocessor;

Ignition lock and power interface are the whether signal detection ends in dormant state of microprocessor, or power input; Whether infrared ray sensing module has people near the signal detection end of fuel tank; When automobile stops, alarm controller interface is the signal detection end whether alarm controller works;

Infrared ray sensing module is arranged on automobile, and above-mentioned alarm controller is an independent circuit module.

As shown in Figure 4, U1 is microprocessor, near object monitor vehicle fuel level height state and oil tank of vehicle dynamically; RS is inner integrated fuel level sensor, infrared emitting module RD0 and infrared emitting and accept module Q0 formation infrared ray sensing module, and infrared ray sensing module is controlled by U1 microprocessor; On microprocessor, draw ignition lock and power interface JP1 and alarm controller interface JP2;

The principle of work of guard against theft oil monitoring fuel-quantity transducer is: when vehicle normally moves, ignition lock provides a voltage signal for alert detecting module, by JP2-6 to U1-11, when U1 detects this signal, U1-13, U1-14 stop the detection to fuel level sensor RS position, detection module sends vehicle operating information command to alarm controller, makes it be in not power consumption of dormant state;

After vehicle stop when operation engine off, ignition lock cuts out U1-11 and can't detect vehicle operating voltage signal, U1-13 controls aerotron Q2, aerotron Q2Q1 and exports to the voltage that fuel level sensor detects, U1-14 detects fuel level sensor RS location status, simultaneously U1-7 output pulse signal drives infrared ray sensing module, and the external infrared detection module of U1-12 is used for reading the power of infrared signal, according to the strong and weak situation of signal, determine and send command status;

When have people near fuel tank near time, when U1-12 detects after infrared ray sensing signal, infrared ray sensing signal is carried out to processing and identification, determine state, if personnel do not send out alarm command near leaving fuel tank at short notice, if stop while surpassing setting-up time, U1-4 sends first method alarm command and by JP2-3, passes to alarm controller and send warning, when there being people to steal fuel level in fuel tank, occur declining, while oil level dropping signal being detected by U1-14, by U1, judge and determine that fuel oil is stolen, now by U1-4, send second method alarm command and pass to alarm controller by JP2-3,

LED1 is working station indicator, indicator lamp Chang Liang during vehicle operating, and when vehicle stop operation enters antitheft detected state, indicator lamp flicker was extinguished after 3 minutes; If break down, indicator lamp glimmers and does not stop always.

As Fig. 5 shows, electric elements of the present utility model are integrated in a circuit card 5, and draw grafting port 6.

As the alarm controller that Fig. 6 shows, the core of alarm controller is also microprocessor, draws guard against theft oil monitoring fuel-quantity transducer interface, ignition lock and power interface on microprocessor, and microprocessor is also connected with annunciator, external alert device in vehicle body; Ignition lock and power interface are the whether signal detection ends in dormant state of microprocessor;

Guard against theft oil monitoring fuel-quantity transducer, alarm controller be by alarm controller interface, the combination of guard against theft oil monitoring fuel-quantity transducer interface, and when having people still not leave in certain hour near near oil tank of vehicle, microprocessor is controlled alarm work in vehicle body; When oil level variation being detected, microprocessor is controlled the work of external alert device.

As Fig. 7 shows, the principle of work of alarm controller is: U2 is microprocessor, JP3 is guard against theft oil monitoring fuel-quantity transducer interface, JP4 is alarm interface, the Complex interface of ignition lock and power interface, by guard against theft oil, monitor the 3rd port of fuel-quantity transducer interface JP3 and take in external command signal, with guard against theft oil monitoring fuel-quantity transducer module communication, U2 determines the mode of operation of annunciator by the impulse singla of the 8th pin identification different coding, when vehicle is in normal operating condition, sensor sends a series of by the impulse singla instruction of specific coding, U2 receives instruction and controls annunciator in dormant state after by conversion identification, substantially do not consume electric energy,

When vehicle stop moves, U2 receives after the cutoff command signal that sensor sends, and makes U2 in waiting for alarm condition; When having people still not leave in certain hour near near oil tank of vehicle, the impulse singla that U2 goes out to report to the police by the 7th human hair combing waste is exported a series of pulse voltages by external aerotron Q4, Q5, control annunciator in the external vehicle body of JP4 (buzzer phone that uses interior of body to carry for reducing costs buzzer phone) and report to the police, remind the driver and conductor who has a rest in car to note taking precautions against fuel oil stolen; If while now receiving oil level variation instruction, U2 the 5th pin simultaneously output alarm impulse singla drives relay K J by aerotron Q6, by JP3 port 7, control outside (high pitch) annunciator (if reducing costs available alternative with electric automobile horn or back-up buzzer) and send high pitch warning, remind driver and conductor at a distance to play fright oil stealer simultaneously;

When having people to cut off the circuit between guard against theft oil monitoring fuel-quantity transducer and alarm controller, U2 can't detect status signal can send chimes of doom equally;

Indicator lamp LED2 is used to indicate controller mode of operation, indicator lamp Chang Liang when vehicle normally moves, after vehicle stop operation engine off, controller enters after security status indicator lamp glimmers 3 minutes and extinguishes, if there is fault-indicating lamp to glimmer always, reminds maintenance.

In fundamental diagram shown in Fig. 4 and Fig. 7, in circuit, be also provided with voltage stabilizer VR1, voltage stabilizer VR2, just very conventional, as long as there is microprocessor, must have it, at this, be not described in detail.

In the utility model, if proposed shown in the circuit square frame shown in Fig. 3, Fig. 6 circuit square frame; To one skilled in the art, can realize easily.
