The technical solution adopted for the present invention to solve the technical problems is: provide a kind of Parking-space information detection method, in parking lot, above each parking stall, wireless ultrasonic pick-up unit is installed, install wireless geomagnetism vehicle detection apparatus at gateway, parking lot place, described wireless ultrasonic pick-up unit and wireless geomagnetism vehicle detection apparatus all carry out radio communication with the radio communication base station in parking lot; Described radio communication base station is used for the status information transmission on parking stall each in received parking lot to custom system; Described wireless ultrasonic pick-up unit detects the state on the parking stall below it in intermittent mode, once find that the state of current detection result and a front testing result is inconsistent, then current parking space state is mail to described radio communication base station by communication; The event information in described wireless geomagnetism vehicle detection apparatus monitor vehicle turnover in real time parking lot, once there be the event information in vehicles while passing parking lot to occur, this event information is mail to described radio communication base station by wireless geomagnetism vehicle detection apparatus immediately, and described radio communication base station broadcasts a sense command to the wireless ultrasonic pick-up unit on all parking stalls; The state on the parking stall below it is detected after described wireless ultrasonic pick-up unit receives sense command, once find that the state of current detection result and a front testing result is inconsistent, then current parking space state is mail to described radio communication base station by communication, upgrade the parking lot status information of custom system via described radio communication base station.
Wireless ultrasonic pick-up unit on described parking stall periodically detects parking stall state according to the cycle set.
Described wireless ultrasonic pick-up unit adopts wireless data communications and powered battery mode to work.
Described wireless geomagnetism vehicle detection apparatus adopts wireless data communications and powered battery mode to work.
Beneficial effect
Owing to have employed above-mentioned technical scheme, the present invention compared with prior art, there is following advantage and good effect: the present invention is by working in longer cycle detection mode by ultrasonic detection technology, while reaching high detection accuracy, average power drawn reduces greatly, this device is enable to adopt powered battery, and Signal transmissions can adopt wireless mode, thus taken into account facility this two large advantage detecting the high and wireless working method of degree of accuracy and bring, the cost input of minimizing installation.Utilize wireless geomagnetism vehicle detection apparatus to carry out Real-Time Monitoring in gateway, parking lot to the vehicle in whole parking lot information of coming in and going out simultaneously, utilize vehicle information of coming in and going out to trigger all parking stalls and carry out a passive detection, the status information of the current each parking stall of real-time update, compensate for the not enough problem of the real-time periodically detected with this.Therefore, achieve and the parking space information real-time high-accuracy in whole parking lot is detected, and the installation of whole detection system is very simple and convenient.
