Design of parking guidance management system based on Internet
In order to improve the operation efficiency of urban parking lots,an Internet-based parking guidance and manage-ment system was designed.The main control chip of the hardware part of the system is STM32F407 single chip microcomputer.According to the acquisition node,which includes high-definition camera,audio device and high-sensitivity ultrasonic sensor,the node will transmit real-time information to the data processing module through the Internet.The communication module adopts two modes:CAN bus communication and WSNs communication.The software workflow and execution steps of the parking guidance management system are given,and an ACO bionic algorithm based on GA algorithm is adopted to make the parking guidance sys-tem have the ability of global optimization.The test results show that the proposed system has a high efficiency of vehicle entry and departure per unit time during peak hours,the number of vehicles is up to 13,and it can provide a shortest route to the designated parking space.
