The selection of detection module sensor
To realize the purpose for reasonably selecting senser element, now the stolen mode of motor vehicle is analyzed.Generally speaking burglar is most normal
Theft means have following several method：
1. vehicle carrying method：Directly vehicle is dragged away or vehicle is packed into other delivery vehicles using trailer and is transported.Such deathwatch
Extremely short the time required to mode, burglar can speed away scene.
2. destroy car body method：Burglar directly destroys motor vehicle door lock or glass in unattended parking site with instrument
It makes a forcible entry into vehicle, is electrically sailed away vehicle with connecing.
3. copy key or unlocking master-hand：Key is replicated or opens car door with unlocking tool, directly vehicle drives away.
4. steal vehicle-mounted object：Burglar dismantles car body exterior part or smashes the interior article of vehicle window theft.
Phenomena such as these behaviors of burglar can cause body oscillating, tilt, while be also 9 ~ 10 μm with centre wavelength
The biological information of human body such as infra-red radiation.According to the abnormal phenomenon that burglar's theft motor vehicle is triggered, appropriate monitoring devices is selected
Data acquisition is carried out, and uses appropriate data processing algorithm, it is possible to realize the purpose of accurate early warning.
In order to extract enough information, realize the accurate judgement to monitoring objective, select sensor that should follow
Basic principle：It reasonably selects sensor and is subject to optimum organization, to realize the demand of system high-precision, low cost；It selects different
The sensor of species, difference in functionality plays the advantage of each sensor, information sharing, the possibility for reduce false, failing to report；Choosing
With multiple congener sensors, rational deployment, removal monitors dead angle, improves the reliability of system.Based on above analysis, choosing
The monitoring modular of burglary-resisting system is formed to lower sensor：
1. microwave Doppler sensor.It can be used for detecting the shifting of human body or object using sensor made of Doppler effect
It is dynamic, the sensor people or object close to when the frequency that receives of receiver change, can be with when frequency is changed to setting value
It is judged as that someone or object enter the early warning range of burglary-resisting system；
2. vibrating sensor.It, can be to the vibration of car body particular frequency bands using vibrating sensor made of acceleration detection device
It is monitored, alarm can be generated in the situation that car body is destroyed by external force；
3. obliquity sensor.Whether obliquity sensor monitoring car body there is change of pitch angle compared with initial position, if this angle
The variation of degree is the threshold value for occurring with specific frequency or reaching setting, it is possible to be judged as that motor vehicle is integrally handled upside down.
4. pyroelectric infrared sensor.The infrared radiation that a length of 9 ~ 10 μm of pyroelectric infrared sensor centering cardiac wave is quick
Sense is able to detect that the infrared information of human body radiation, may be used as the interior monitoring devices of human body invasion；
5. Hall switch device.It can be to the car door of motor vehicle, engine compartment cover and case cover by Hall switch device
Illegal open is monitored.
Change, body oscillating, the change of car body position state and biological information of human body of above several Sensor monitoring wave frequency rates etc.
Different aspect, then by being reasonably laid out removal monitoring dead angle, it becomes possible to the enough information needed for motor vehicle antitheft is obtained, it is maximum
The uncertainty of information is eliminated to degree, improves the reliability of alarm
Meet the fusion treatment of alert information
Multi-sensor information fusion refers to collaboration using multiple sensors, and various heat transfer agents is effectively combined, shape
The process of the uniformity description to environment is obtained into high performance sensory perceptual system.Compared with single-sensor, multisensor letter
Breath merges the uncertainty in reduction information, the accuracy of raising system acquisition information, reduces the cost of system, improves system
Reaction speed etc. has significant advantage, therefore information fusion technology may be employed, the data that monitoring modular gathers are carried out
Fusion treatment.
Information fusion model can be represented from several respects such as function, structure and mathematical models to study.Functional mode is from melting
The process of conjunction is set out, description information fusion include which major function, database and into row information merge when system respectively form
Interaction process between part；The composition that structural model is merged from information illustrates the soft and hardware of information fusion system
The man-machine interface of composition, related data flow, system and external environment；Mathematical model is then information fusion algorithm and integrated logic.
The functional mode of multi-sensor information fusion can be divided into the fusion of detection grade, tracking fusion, property level fusion three
A level.And alert levels are divided into " vehicle carrying ", " car body destruction ", " illegal to open " and " enter vehicle to steal by this burglary-resisting system
Surreptitiously " four classes, and judged using different information fusion models.Wherein " vehicle carrying ", " car body destruction " and " illegally open
Open " it is the information fusion for detecting grade, is a distributed detection system, each group Sensor monitoring target is mutual indepedent, Lothrus apterus,
Their Information Pull combined techniques can be carried out to comprehensive superposition；" entering vehicle theft " is the fusion of property level, need to be to target identities
Carry out Combined estimator, can utilize instruct method progress fusion treatment.
In detection grade fusion, the structural model of system uses serial structure.Judge in microwave Doppler sensor node
As a result on the basis of, the detection information with inclination sensor, vibrating sensor and Hall switch device merges respectively, processing procedure
For：The reaction signal of microwave Doppler sensor shows someone or object proximity.When people or the close of object reach early warning distance
Afterwards, if inclination sensor judges that tilting of car body angle reaches the threshold value of setting, show there is " vehicle carrying " situation；If vibrating sensing
Device also generates sensing to the vibration of car body particular frequency bands, then is judged as " car body destruction "；If it is installed on the Hall switch of car door
Device is made a response, and shows car door or front and rear hatchcover by " illegal to open ".Its respective structure type.
Tree is used for the deterministic process of " the entering vehicle theft " of the fusion of application attribute grade.According to " car body destruction "
Or the node judging result of " illegal to open ", in addition the detection information of infrared sensor, it is possible to judge whether someone enters
It is interior.
