Abstract

The utility model provides an antitheft monitoring fuel quantity sensor of an automobile. The antitheft monitoring fuel quantity sensor comprises a support, a data tube, a magnetic floater, a fuel inlet tube of a fuel tank, a fuel return tube and a circuit controller. A core of the circuit controller is a microprocessor, and the data tube and the magnetic floater form a fuel quantity sensor. The technical scheme includes that the microprocessor is connected with an external infrared sensing module, and the infrared sensing module is used as a signal detecting end for detecting whether people approach the fuel tank or not; an alarm controller interface is used as a signal detecting end for detecting whether an alarm controller works or not when the automobile is parked. The antitheft monitoring fuel quantity sensor has the advantages that an antitheft fuel monitoring function is integrated in the fuel quantity sensor, the antitheft monitoring fuel quantity sensor can be used just like a common fuel quantity sensor, and is used with the external alarm controller, so that an antitheft fuel alarm effect can be realized, protection measures can be automatically implemented when the automobile stops running, the antitheft monitoring fuel quantity sensor can give an alarm when fuel is about to be stolen, a driver can be reminded of paying attention to the automobile, thieves can be scared away, and loss due to thievery on the fuel of the automobile can be reduced.

Description

Automobile burglar oil monitoring fuel-quantity transducer

Technical field

The utility model relates to automobile oil mass sensor, especially automobile burglar oil monitoring fuel-quantity transducer.

Background technology

At present; long-distance freight transportation vehicle is increasing; many people do not stop the transportation around goods is busy; driver and conductor is in freight transportation process; have for a long time and all with car, travel; because the long-distance fatigue of transportation is done suitable rest adjustment and can hardly be avoided; some lawless persons make profit as one's only aim; be certain about driver's fuel oil in oil tank of vehicle of setting about to steal when tired rest; because the fuel tank of large-scale haulage vehicle all exposes; without any safeguard measure fuel oil, be easy to stolenly, cause damage to car owner and driver.

Summary of the invention

The utility model proposes automobile burglar oil monitoring fuel-quantity transducer, integrated fuel-quantity transducer and guard against theft oil monitoring are integrated, product can be used as conventional oil quantity sensor, coordinate antitheft alarming controller to use, play guard against theft oil alarm function, can be when vehicle stop moves automatic guard setup, when having people to steal fuel oil, send warning, remind driver to note on the one hand, frighten on the other hand thief away, thereby lower the stolen loss of vehicle fuel.

The technical solution adopted in the utility model is: automobile burglar oil monitoring fuel-quantity transducer, comprise bearing, data pipe, magnetic float, fuel tank oil inlet pipe, scavenge pipe, circuit controller, the core of circuit controller is microprocessor, data pipe, magnetic float forms fuel-quantity transducer, on microprocessor, draw ignition lock and power interface, a control port of microprocessor is connected with transistor switching circuit, to fuel level sensor, provide detectable voltage signals, it is characterized in that: microprocessor is connected with outside infrared ray sensing module, on microprocessor, also draw alarm controller interface,

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

Beneficial effect: the integrated fuel-quantity transducer of the utility model and guard against theft oil monitoring are integrated, product can be used as conventional oil quantity sensor, be used in conjunction with outside alarm controller, play guard against theft oil alarm function, can be when vehicle stop moves automatic guard setup, when having people to steal fuel oil, send warning, remind driver to note on the one hand, frighten on the other hand thief away, thereby lower the stolen loss of vehicle fuel.

Embodiment

As Fig. 1,2 automobile burglar oil monitoring fuel-quantity transducer, comprise by bearing 1, data pipe 4, magnetic float 5, fuel tank oil inlet pipe 8, scavenge 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 pipe 8, scavenge pipe 3 connect on bearing, and fuel tank oil inlet pipe 8, scavenge 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 pipe is connected with screen pack 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, data pipe shown in Fig. 1, magnetic float form fuel-quantity transducer, on microprocessor, draw ignition lock and power interface, a control port of microprocessor is connected with transistor switching circuit, to fuel level sensor, provide detectable voltage signals, microprocessor is connected with outside infrared ray sensing module, also draws alarm controller interface on microprocessor;

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;

Principle of work of the present utility model 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 kill, ignition lock cuts out U1-11 and can't detect vehicle operating voltage signal, U1-13 controls triode Q2, triode 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, sending second method alarm command passes to alarm controller by JP2-3 and sends forte and report to the police,

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

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

In the utility model, as long as proposed the circuit square frame shown in Fig. 3, to one skilled in the art, can realize easily.
