--bluetooth communication module 3: the data transfer of core processor 1 is become to meet the signal of Bluetooth communication protocol standard, and will receive the signal that meets the Bluetooth communication protocol standard and convert the data that core processor 1 can receive to.
Core processor 1 is connected with bluetooth communication module 3, infrared induction module 4, control unlocking signal output loop 14 in also being connected with simultaneously, be used for the release of core processor 1 and shut instruction sending automobile to and controlling 16, and carry out circuit such as driving engine or automotive pump or connect mechanism and carry out the operation of release or locking; Core processor 1 also is connected with status indicator lamp 15, is used to refer to the mode of operation of Car Burglar Alarm, at the state of setting up defences by certain frequency scintillation; Core processor 1 is connected with anti-theft alarm loudspeaker control loop 12, is used to control anti-theft loudspeaker 18 and sends chimes of doom and prompting sound; Core processor 1 is connected with steering indicating light control loop 13 and is used to control indicator 17, is used to point out the car owner.
Working process of the present utility model is: infrared emission, receiving sensor are built in the automobile passenger storehouse, the preceding windscreen and the side window glass that see through automobile send infrared signal outward to car body, and the continuous intensity of returning the infrared signal of penetrating that detects, judge by software synthesis whether car owner or object enter the actual induction zone, and send relevant information to core processor.
Because infrared transmission/receiving sensor sends signal outside car in glass, and because the shape and the light transmittance of preceding windscreen and side window glass have nothing in common with each other, just be same the position that sensor is installed in vehicle of the same race, but because preceding windscreen and side window glass pad pasting whether, with the film that pastes different brands infrared reflection all there is very strong influence, and the residing environment of vehicle to be the rainy day different with various natural conditions such as fine, daytime and evenings, these factors all might cause the erroneous judgement of infrared induction module disconnected.In order to realize the commonality of product, can adapt to above various vehicle, the different installation sites of vehicle of the same race, and the pad pasting of the different brands that pastes of vehicle glass, the problem above my company solves by following design:
1, the signal of infrared emission is modulated, and the signal of infrared pickoff reception is amplified and demodulation, to get rid of the infrared interfering signal of wavelength of the same race in environment and the background.
2, owing to the reflectivity and the adhering film to glass of glass curvature, glass are fixed, under the certain situation of infrared emittance, the echo amplitude and the phase place that receive are also fixed, therefore by hardware and software filtering, compare by judging 15 seconds the mean intensity of Infrared intensity and front that receives whether significant change is arranged, have human body or object to enter the actv. reflector space if having then judge, if there is not significant change, then thinking does not have human body or object in the actual induction zone.Get rid of of the influence of this fixing infrared external reflection in this way to car owner's position judgment.
3, under the environment in daytime or evening, in short time (for example 15 seconds), background can be thought variation seldom (position of the position of intensity of sunlight, the sun and the moon and street lamp) can not change in other words substantially.Therefore pass through software filtering, compare by judging 15 seconds the mean intensity of Infrared intensity and front that receives whether significant change is arranged, have human body or object to enter the actv. reflector space if having then judge, if there is not significant change, then thinking does not have human body or object in the actual induction zone.Get rid of this factor of environmental in this way and get rid of.
4, car rains outward, because infrared pickoff is over against the infrared signal of the raindrop meeting reflecting part of vehicle glass outside, cause erroneous judgement disconnected, therefore by in certain distance, placing two or more infrared receiving sensors, because infrared launcher is placed on the geometric centre of receiving sensor, therefore each sensor of normal circumstances receives infrared signal strength and understands some difference, but not too large.
Software compares by 15 seconds the mean intensity of Infrared intensity and front of judging each infrared pickoff reception whether significant change is arranged, and the amount that requires to change is wanted basic identical effective detection of just calculating.Since two or more infrared pickoffs over against the mobility status of raindrop of glass outside can be not just the same, certainly have slight difference, and employed infrared pickoff can detect this difference, whether the variable quantity of judging each infrared receiving sensor by software similar methods, can be implemented in and can not judge in the rain in disconnected effective surveyed area whether human body or object are arranged by accident.And the car owner in the accurate inspection of the needs service area is much larger than the distance between two or more sensors, so the signal situation of change that two or more infrared reception propagated sensation devices are received is the same substantially, therefore can normally detect the car owner and whether reach near the service area of car door.
