This system aims to accelerate users to find parking spaces and improve the management efficiency of the parking lots. This paper introduces the process of establishing the mesh networks in detail and uses HC-SR04 type ultrasonic sensor and CC2430 sending and receiving module to constitute the information of wireless networks’ collection node. The paper also puts forward the best parking model based on the shortest path algorithm and uses LED dot matrix display technology to complete the display of information and the function of guilding. The paper has analyzed the users’ behavior of the micro parking in detail and has also concluded the main factors which has effect on parking. It puts forward the best parking model based on the shortest path algorithm. It changes the assurance of the best parking space into the solution of the shortest path of weighted graph in graph theory. Introduce the ant colony algorithm, Dijkstra algorithm and Floyd algorithm carefully. Choose the best algorithm as the parking guidance algorithm of the Parking lot. Then, describe the best parking space after making a little change of the algorithm. Taking advantage of Matlab software programs and s
