Infrared reflection-type wireless detector and parking lot parking spot control system

The utility model relates to an infrared wireless detector of a parking lot and simultaneously relates to a parking lot parking spot control system, wherein the infrared wireless detector is used to detect an occupation situation of the parking lot parking spot. The infrared reflection-type wireless detector comprises a micro-control unit, an infrared sensor, an ambient light sensor, a wireless communication module, a power supply, a wireless remote control module and a LED indication module, wherein the micro-control unit is used to process signal data; the infrared sensor is used to emit an infrared ray and detect an infrared signal reflected by a vehicle so as to determine a vehicle distance and a parking state; the ambient light sensor is used to detect ambient light changes and start detection work of the infrared sensor; the wireless communication module is used to send and receive the signal data; the power supply is used to provide power for each part of the detector; the infrared sensor, the ambient light sensor and the wireless communication module are connected with a micro-control unit signal respectively; the wireless remote control module is connected with the micro-control unit signal and is used to emit the signal to remotely control a display state of an illuminating lamp in the parking spot; the LED indication module is used to display a working state of the detector and a power supply state.
