Abstract: For the core commercial area with an inch of land, the underground three-dimensional garage is a high-quality solution for parking spaces and parking needs without occupying space on the ground. How to reduce the demand for parking space as much as possible while ensuring the normal operation of the system is a problem that plagues the design of the stereo garage system. Based on this, this article introduces a threedimensionalgarage electrical and control system, expounds its design ideas, control principles and functional characteristics. Practice has proved that the system has strong adaptability to vehicle models, low construction cost of electrical system, and high automation of parking equipment, it provides a new idea for the traditional underground mechanical parking system to develop to automation, convenience and high effi ciency
