The invention discloses a vehicle type recognizer. By using the vehicle type recognizer, the height of a light screen sensor can be adjusted adaptively according to the height of a mounting base body, the vehicle type recognizer is capable of adapting to various terrains, and can be used at a high temperature, low temperature, and under high-humidity and severe environment, the temperature and the humidity in the vehicle type recognizer equipped with the light screen sensor can be controlled automatically, normal stable using of the light screen sensor is ensured and high adaptability is achieved; moreover, energy conservation is achieved since the light screen sensor and double-piezoelectric-film sensors in the vehicle type recognizer are started only to recognize a vehicle when the vehicle is coming; in addition, a distance sensor can detect the distance from the vehicle, a person or other object to the vehicle type recognizer and give an alarm, so that the vehicle type recognizer is effectively prevented from being scraped by the object, moreover, an anti-theft function is achieved.
