Abstract
Present invention discloses a kind of automobile oil tank anti-theft systems, bottom in automotive oil tank is fixed with pressure sensor, the pressure sensor exports inductive signal to controller, the controller connection CAN bus obtains vehicle current working parameter, to relay, the control terminal of the relay is connected on the conducting wire of connection battery and loudspeaker the controller output drive signal.The advantage of the invention is that can remind car owner's vehicle oil stolen in time, the property safety of the people ensure that, and principle is simple, the cost of investment is less, profit reciprocation with higher.Existing market vehicle on sale does not occur the new-type fuel tank with this function, and the application of device can attract consumer, increase the desire to purchase of consumer.
Description
Technical field
The present invention relates to automotive oil tank fields.
Background technique
The stolen oil of oversize vehicle, be one very puzzlement oversize vehicle driver the problem of, some illegal points in society
Son is made a desperate move to obtain wrongful interests, is offended state's laws and is invaded people's interests.Wherein " oil thief " is exactly it
In it is typical a kind of, they set about mainly for the fuel tank of large-scale vehicle, and theft vehicle oil, which is resell at a profit, exchanges interests, such event for
Often occur, passenger-cargo carriage driver has a horror of pain disease.
Heavy Duty Commercial Car fuel tank is generally fairly simple, typically exposed outside vehicle, and the vehicle of factory is not any
Anti-theft protection measure so that " oil thief " stolen is easy.
Summary of the invention
The technical problem to be solved by the present invention is to realize that one kind is at low cost, structure is simple, can reliably carry out to fuel tank
The system of anti-thefting monitoring.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of automobile oil tank anti-theft system, automotive oil tank
Interior bottom is fixed with pressure sensor, and the pressure sensor exports inductive signal to controller, and the controller connects CAN
Bus obtains vehicle current working parameter, the controller output drive signal to relay, the control terminal string of the relay
It is associated on the conducting wire of connection battery and loudspeaker.
The vehicle current working parameter is the revolving speed and speed of engine.
System is equipped with the communication unit communicated with user mobile phone, the controller output drive signal to communication unit.
Control method based on the automobile oil tank anti-theft system:
When engine speed and speed are simultaneously 0, start anti-theft program；
Obtain pressure value P0 in simultaneously storage tank；
Monitor tank pressure value P1 in real time；
When P1 is less than P0 and difference is greater than the set value, loudspeaker alarm is controlled；
When engine speed is greater than 0, anti-theft program is closed.
Alarm signal is issued to user mobile phone by communication unit when P1 is less than P0 and difference is greater than the set value.
The advantage of the invention is that can remind car owner's vehicle oil stolen in time, the property safety of the people, and principle ensure that
Simply, the cost of investment is less, profit reciprocation with higher.Existing market vehicle on sale does not occur novel with this function
The application of fuel tank, device can attract consumer, increase the desire to purchase of consumer.
Detailed description of the invention
The content of width attached drawing every in description of the invention expression is briefly described below:
Fig. 1 is automobile oil tank anti-theft system block diagram.
Specific embodiment
Below against attached drawing, by the description of the embodiment, for example related each component of a specific embodiment of the invention
Shape, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle, manufacturing process and
Operate with method etc., is described in further detail, to help those skilled in the art to inventive concept of the invention, technology
Scheme has more complete, accurate and deep understanding.
As shown in Figure 1, increasing a pressure sensor in the bottom of oil tank of vehicle, pressure sensor main function is monitoring
The pressure when position, we judge the increase either reduction state of oil mass in fuel tank by the variation of pressure.
Under normal conditions, vehicle oil is stolen occurs mainly in night, and at this time the state of entire vehicle is stationary state,
Main feature under vehicle stationary state is exactly the revolving speed and speed while being 0 of engine, we are in the present invention with features described above
The basis signal started to work for follow up device.After the control unit of pressure sensor receives above-mentioned signal, pressure sensing
Device is started to work, and pressure sensor records the pressure of the position at this stage.When stationary vehicle, one can consider that in oil tank of vehicle
Oil be it is stationary, the pressure signal of pressure sensor should be a definite value at this time, definite value at this time we be defined as
P0.When " oil thief ", which opens mailbox, to steal, the liquid level in oil tank of vehicle can be reduced, and liquid level reduction means in fuel tank
Pressure can generate variation, equally be thought deeply in turn, and the pressure signal that position is fixed under vehicle stationary state, in fuel tank occurs
Variation indirectly shows stolen with oil in oil tank of vehicle, this fashionable dress it may be considered that the liquid level of fuel tank internal is gradually reducing
Setting remind car owner to check in time.
Specific security method: stationary vehicle, the pressure sensor control unit in fuel tank receive engine and turn
When the signal that speed and speed are simultaneously 0, pressure sensor work, tank pressure P0 when detecting static；
During pressure sensor works, if the pressure signal of pressure sensor does not change, pressure is big in other words
Small signal when certain section is hovered illustrates that any variation does not occur with oil mass in oil tank of vehicle；When pressure sensor is believed
When number great changes will take place and pressure is becoming smaller always, we, which define when oil pressure pressure signal is reduced to P1 by P0, is determined as danger
Point illustrates being gradually decreased in oil tank of vehicle with oil at this time, indicates that vehicle is stolen with oil for the present invention, at this time pressure sensing
The pressure signal of variation is inputed to car alarming control unit by device controller；
After car alarming unit receives alarm signal, immediately start the warning device of vehicle, car owner is reminded to check in time
Oil tank of vehicle, the alarm method can be short message prompting and be also possible to be integrated in inside vehicle with vehicle, while vehicle interior
Music centre loudspeaker reminds car owner.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
