Detecting method for empty parking spot of mechanical garage

Abstract

The invention discloses a detecting method for an empty parking spot of a mechanical garage. The detecting method includes detecting current values generated by lifting a motor under a parking condition and a non-parking condition; comparing the current values with an initial value; judging whether or not a vehicle parks on the parking spot according to the comparing result. A detecting structure is simple and compact, and a detecting switch is not required besides a distribution box. The detecting method is high in accuracy, energy saving, economic and environment friendly. By the use of the detecting method, data support is provided for further development of the mechanical garage, to be specific, for a horizontally lifting garage, the lower empty parking spots can be parked firstly according to the judged data, thus, parking and taking time can be saved greatly, electric energy is saved, and center of gravity of the structure moves down to allow safety to be facilitated.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a method for detecting the vacancy of a mechanical garage parking space. Background technique [0002] Nowadays, mechanical parking garages are generally designed in clusters, with many and dense parking spaces. For example, in the underground three-dimensional garage, if there is no manual statistics for each garage unit, it is not easy to see the parking space on the upper floor from the car. This requires parking guidance systems. The parking guidance system can guide the vehicle to drive to an area where there is a parking space. After parking in an empty parking space, the parking space is judged as parked, and the parameters of the guidance system are changed. In short, a parking guidance system needs to be supported by data on whether the garage is vacant or not. [0003] In the past technology, the vacancy judgment of flat parking spaces in large parking lots is ge...

Problems solved by technology

This technology can also be applied to mechanical three-dimensional parking spaces to judge the vacancy of parking spaces. The traditional method adds radio eye detection to each parking space, but the number of detection points increases, the structure is complicated, the failure rate increases, and the accuracy is not high (if there are foreign objects Covering the probe will also show that the parking space has been parked), and the structural cost will increase by about 600 yuan per parking space
