Infrared light curtain vehicle sensor and method

Abstract

The invention relates to an infrared light curtain vehicle sensor and method. The infrared light curtain vehicle sensor comprises a main sensor, an auxiliary sensor and a system micro-controller, wherein the main sensor comprises a horizontal infrared light curtain sensor capable of sensing vehicle driving-in information and vehicle axle distance length information; and the auxiliary sensor comprises two infrared light curtain sensors which are perpendicular to each other and can measure the widths of vehicles which are driven in. The infrared light curtain vehicle sensor can be used for parking navigation of vehicles in a parking lot conveniently, and the problem that a vehicle navigator or a mobile phone map close to a parking lot is poor in navigation precision, and even cannot be usedis solved; if the infrared light curtain vehicle sensor is combined to a visible light LED array, one-to-one accurate positioning parking navigation consistent to the driving slight of a driver is obtained; by visible light LEDs, error-less walking navigation for a driver and passengers who enter or leave away from the parking lot can be provided; and by voice and light signals, whether the vehicles park and are positioned accurately or not can be prompted, and scratching is prevented.

Description

【Technical field】 [0001] The invention relates to the field of vehicle management in parking lots, in particular to a vehicle induction detection device for indoor parking lot vehicle management of infrared vehicle sensors, in particular to an infrared light curtain vehicle sensor and method. 【Background technique】 [0002] Vehicle detection technology has become very common, and the current mainstream technology is the ground induction coil technology. In indoor parking applications, the limitation of ground induction coil technology is that it is impossible to obtain the geometric size information of the vehicle. Most of them are installed in an embedded way. The installation is more troublesome and inconvenient to use, especially the parking space usage status information and parking space cannot be provided for the management system. The size information of parked vehicles is inconvenient to realize real-time dynamic management of parking spaces, let alone provide one-to...
