Abstract
The invention discloses an automobile antitheft device based on multiple sensors. The automobile antitheft device aims to solve problems that false alarm rate of existing alarms keeps high while most of the existing alarms are voice alarms, accordingly alarming sound becomes noise polluting environments, furthermore, alarm distances are limited, and automobiles cannot be effectively controlled after the alarms give an alarm. The automobile antitheft device comprises a micro-control unit MCU, a power module, a keyboard module, an alarm module, a sensor group module and a global communication GSM (global system for mobile communications) module, the micro-control unit is respectively connected with the power module, the keyboard module, the alarm module and the sensor group module, and a sensor group consists of a plurality of sensors. When the automobile antitheft device judges that an automobile is in an alarming condition, the micro-control unit MCU directly transmits automobile condition information to an automobile owner via a GSM network, an ignition system or an oil circuit of the automobile is actively blocked, and accordingly an antitheft purpose is achieved.
Description
Technical field
The present invention relates to technical field of automotive electronics, be specifically related to a kind of automotive theft proof system.
Background technology
Develop rapidly along with electronic information technology; Sensor technology, In-vehicle networking, data communication, Computer Processing technology and intelligent control technology etc. are widely used in the automobile burglar technology, and the automobile burglar product develops to highly intelligent, functional diversities direction.Main flow automobile burglar equipment in the market can be divided into mechanical type Car Burglar Alarm, electronic type Car Burglar Alarm, chip type Car Burglar Alarm and network type Car Burglar Alarm by its structure and function.Yet all there is certain shortcoming in these automobile burglar technology, mainly show two sides: the one, and the high and most annunciator of alert device rate of false alarm all is an audio alert, chimes of doom has also become the environmental pollution noise like this; The 2nd, alarm distance is limited, after warning, can not effectively control car.
Summary of the invention
To above-mentioned prior art, the technical matters that the present invention will solve is: the high and most annunciator of annunciator rate of false alarm all is an audio alert, and chimes of doom has also become the environmental pollution noise like this; Alarm distance is limited, after warning, can not lack car is effectively controlled.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of alarms and security systems for automobiles based on multisensor is provided; Comprise micro-control unit MCU, power module, Keysheet module, alarm module and sensor groups module; Micro-control unit MCU is connected with power module, Keysheet module, alarm module and sensor assembly respectively; It is characterized in that: also comprise the global communication gsm module, described global communication gsm module confirms that in system automobile is in the state of meeting the alert condition and sends note down or dial and report to the police to the car owner; Said sensor groups module is made up of small microwave motion sensor, acceleration pick-up, the two sensitive first pyroelectric infrared sensors of passive type and Hall element.
Said power module is that related device is supplied power in the system with Vehicular accumulator cell as power supply source and the direct supply that is converted into 5V and 3.3V.
Said alarm module car light when carrying out short message alarm, audio alert constantly glimmers, and abnormal condition appear in the expression automobile; Confirm that in system automobile is under the state of meeting the alert condition, micro-control unit MCU directly blocks the firing circuit or the oil circuit of automobile.
Compared with prior art, the beneficial effect that has of the present invention shows:
Make full use of otherness and the complementarity of multiple sensors on performance, the sensor information of gathering is merged through active data adjudicate alert again,, strengthen the reliability of anti-theft system to reduce the rate of false alarm of annunciator.On alarm response, the GSM module that induces one relies on cordless communication network to make Car Burglar Alarm not receive the restriction of distance.When judging that automobile is in the alert, the micro-control unit MCU of anti-theft system will directly issue the car owner to vehicle condition information through the GSM net, further reach theft-proof purpose through ignition system or the oil circuit of blocking automobile again.
Description of drawings
Fig. 1 is the native system hardware block diagram.
The specific embodiment
To combine the accompanying drawing and the specific embodiment that the present invention is done further description below.
The present invention includes micro-control unit MCU, power module, Keysheet module, alarm module and sensor groups module; Micro-control unit MCU is connected with power module, Keysheet module, alarm module and sensor assembly respectively; It is characterized in that: also comprise the global communication gsm module, said sensor groups is made up of several sensors.
Wherein, the sensor groups module is made up of four kinds of sensors, and the monitoring to the real time environment of vehicle is accomplished in their collaborative works; Power module then provides electric energy by the Vehicular accumulator cell step-down; The alarm response module is responsible for the relevant treatment behind the micro-control unit MCU judgement alert, sound and light alarm, sends the SMS short message and with the operation of waiting indefinitely of automotive ignition system or Fuel path lock; The information that micro-control unit MCU then gathers sensor groups is handled and is adjudicated, if judgement is alert, micro-control unit MCU will notify the alarm response module, informs the relevant action of carrying out.
Embodiment one sensor-level module
The sensor groups module is made up of small microwave motion sensor, acceleration pick-up, the two sensitive first pyroelectric infrared sensor RE200B of passive type and Hall element, is responsible for collection and first treatment to automobile real time environment status information.
Embodiment two warning corresponding modules
Automotive theft proof system is also constantly flicker of car light when carrying out short message alarm, audio alert, and abnormal condition appear in the expression automobile.Confirm that in system automobile is under the state of meeting the alert condition, microprocessor can carry out automobile from latching operation, and micro-control unit MCU directly blocks the firing circuit of automobile, even if the burglar also can't be driven away car into the car.
Flashing light alarm and automobile self-locking system utilize the I/O interface control darlington array of microprocessor, and when " IN " pin input high level, corresponding " OUT " pin drags down the conducting of power relay coil with the pin level of power relay; When " IN " pin input low level, corresponding " OUT " pin outgoing level is identical with the chip power supply level, promptly identical with the relay input voltage, the relay coil blocking-up.Because the adhesive (open contact) of relay contact, the signal with the I/O mouth of microprocessor that breaks off (normally closed contact) change; Make that microprocessor can Control of Automobile car light circuit and the switching of engine ignition circuit, and then realize the flashing light alarm of automobile burglar and from latching operation.The warning execution module can also use traditional speech pattern to report to the police when the GSM network is reported to the police.Native system is selected digital pulse coding modulating voice synthesis chip for use, and this chip is to be stored in the chip after the analog signal with sound becomes digital signal, is triggered the speech chip of audio playback by level signal.
