Design and Analysis of Parking Guidance System for Underground Intelligent Stereo Garage in Downtown Business District

The basses of the intelligent measurement and control system used in underground stereo garage at the downtown business district were investigated. Firstly, the principal constituents for vehicle storage and the intelligent supervision systems were explored, the scheme involves the warehousing guidance, access mode and transmission system. Secondly, the modules of overrun detection and the parking place detection in the vehicle guidance system were successfully designed. Thirdly, three-dimensional information of the storage vehicle (i.e., length, width and height) and the position of the vehicle was collected by employing semiconductor lasers and peripheral circuits. STC89C52 Single-chip Microcomputer was adopted to improve the signal acquisition and control the voice prompt and light guide information and their output. Based on this information, the coding, debugging and testing of the control program were completed. The research of the parking vehicle storage intelligent guidance control at the downtown business district reduced the garage control cost, to a certain extent, and improved the cost-effective, which has an important significance for popularization and application of stereo garage.
