Detailed description of the invention
We combine to illustrate and are specifically described the utility model below:
Fig. 1 is the structural representation that a kind of vehicle intelligent of the present utility model responds to anti-infringement warning, this system comprises microwave proximity transducer 1, audio frequency voice operated sensor 2, ambient light sensor 3, processor platform 4, wireless signal transceiver 5, vehicle-mounted video monitoring host 6, infrared light compensating lamp 7, wherein: microwave proximity transducer 1, audio frequency voice operated sensor 2, the signal output part connection handling applicator platform 4 respectively of ambient light sensor 3, the infrared light compensating lamp 7 of processor platform 4 control linkage, and by adopting radio communication between the wireless signal transceiver 5 of spi bus connection and vehicle-mounted video monitoring host 6.。
The logical organization that native system respectively forms is as shown in Figure 2:
Microwave proximity transducer 1 is made up of microwave Doppler module 11 and filter amplification circuit 12, this microwave proximity transducer is the microwave detector for moving object adopting Doppler radar (Doppler Radar) principle design, sent and reception 5.8GHz microwave signal to 360 degree of spaces by active oscillator circuitry by microwave Doppler module 11, it is an intermediate-freuqncy signal that the difference on the frequency of transmission and Received signal strength exports, and filter amplification circuit 12 includes an op amp, export to processor platform 4 by after intermediate-freuqncy signal filter and amplification;
Audio frequency voice operated sensor 2 is made up of microphone 21, audio amplifier circuit 22, active bandpass filiter circuit 23, level sensor chip 24.The aud. snl. collected by microphone 21, through audio amplifier circuit 22, amplitude is amplified certain multiplying power, aud. snl. after amplification is by active bandpass filiter circuit 23 frequency-selecting, the especial sound signal produced when filtering out this car of infringement is input to level sensor chip 24, and after sound reaches some strength, level sensor chip 24 exports a high level to processor platform 4.
Ambient light sensor 3 is made up of photosensor 31 and resistance sampling circuit 32.Photosensor 31 produces the electric current of different current value, through resistance sampling circuit 32, forms certain magnitude of voltage and exports to processor platform 4.
Processor platform 4 comprises microprocessor 41, and micro-process adopts MSP430 series monolithic.The outward sign that microwave proximity transducer 1, audio frequency voice operated sensor 2 and ambient light sensor 3 are collected by microprocessor platform 4, the I/O interface being aggregated into microprocessor 41 carries out analyzing and processing, the detecting of intelligence and distinguish target close to and encroach on, and in good time send warning.
