The purpose of this utility model is to overcome the defect that prior art exists, and provides a kind of not affected by environment, be applicable to underground parking or open parking ground, and accuracy of detection is high, without wiring, greatly reduces the wireless vehicle location probe of wiring cost and difficulty.
The technical scheme that realizes the utility model purpose is: a kind of wireless vehicle location probe has feed circuit, magnetoresistive transducer, single-chip microcomputer and wireless zigbee communication module; The output terminal of described feed circuit connects the input end of magnetoresistive transducer and the input end of wireless zigbee communication module simultaneously; Described magnetoresistive transducer all is connected with the single-chip microcomputer two-way communication with wireless zigbee communication module.
The described feed circuit of technique scheme have power supply and low pressure difference linear voltage regulator; The input end of the output termination low pressure difference linear voltage regulator of described power supply; The output terminal of described low pressure difference linear voltage regulator connects the input end of magnetoresistive transducer and the input end of wireless zigbee communication module simultaneously.
The described magnetoresistive transducer of technique scheme is three axle magnetoresistive transducers, and the detection frequency of the geomagnetism detecting chip in magnetoresistive transducer is 1Hz.
Between the described magnetoresistive transducer of technique scheme and single-chip microcomputer, by the I2C interface, be connected.
The described power supply of technique scheme is lithium ion battery, and the voltage of power supply is 3.7V, and the capacity of power supply is 3500mAh.
After adopting technique scheme, the utlity model has following positive effect: whether the utility model can detect this parking stall, device place in time has car to stop, and is sent to receiving equipment by wireless mode, without wiring, installs simple.
