The embodiment of the invention provides a parking space state detection method and system. The method comprises the following steps: acquiring magnetic field data of a parking space based on a magnetic field detection method; and if the magnetic field data is in a misjudgment threshold interval, judging the final state of the parking space based on the combination of the magnetic field detectionmethod, the infrared detection method, the millimeter wave detection method and the ultrasonic detection method, otherwise, judging the final state of the parking space based on the magnetic field detection method. According to the method and the system provided by the embodiment of the invention, the final state of the parking space is judged through magnetic field detection, infrared detection,millimeter wave detection and ultrasonic combined detection under the condition that misjudgment possibly exists in magnetic field detection, so that the false detection rate and the missing detectionrate can be reduced. Moreover, except for the magnetic field detection device, other detection devices are started only when the magnetic field detection device may misjudge, the power supply is turned off in other time, and the other detection devices are short in working time and have little influence on the overall power consumption.
