Investigation Of Intelligent Self-service Parking System

Due to the rapid development of China’s economy, the standard of living improves quickly. The car increased year by year. We enjoy the convenient, efficient, comfortable that the car takes, also plagued by the traffic congestion and parking issue. The urban has a very high population density, but the land resources are limited, most parking lot of residence area, shopping malls, office buildings are built underground. In this underground parking lot people may easily disoriented because of lack of light, narrow and small space, design and other factors. The owner may spend more time on find a parking space or their own car, especially in the large underground parking lot. This may not only caused low availability of the parking resources, but also take the traffic congestion, even affect the road traffic. So how to design intelligent parking management system that can solve the problem that was mentioned.At present, most of the parking management systems are focus on the ―pass in and out faster‖ charge management. Consider less on the automation, intelligence, integration and humanize. To solve this problem, this paper put forward a self-service parking management system, complete parking space monitoring and management, park allodium, get car self-service, get out guide and payment. It include parking card, monitor, CAN communication node, CAN-RS232 node, PC, parking guide, get car terminals. The parking card based on control chip and wireless chip, used to complete the data transmit between parking card and monitor, make the card and monitor a group, and then can accomplish car and parking space connect. Monitor transfer the data to PC by CAN communication node and CAN-RS232 node, and accomplish the data processing by PC, the communication protocol chooses CAN bus. Parking guide help owner parking by publish parking space information actual time. The get car terminals help owner find car quickly by show the car location. The parking cost calculation complete through the PC software. Through the system on the one hand can improve the availability of parking lot, to some extent, also avoid resource waste and parking lot traffic congestion due to the unreasonable manage, on the other hand can help owner avoid unnecessary waste of time, improve the convenience and parking experience for owner.This paper develops and test around the hardware part of the system. Design and work on the parking card, monitor, CAN communication node, CAN-RS232 node, PC, parking guide. Choose the control chip STM32 into each node, complete control and processing, and use the NRF24L01 finish wireless communication. The parking space monitoring and parking guide is finished and test in this paper. Though the test of hardware part, the nodes can finish the preinstall function, the hardware part can be accurate and reliable operation, achieve the design goal, provides a basis for the system to further optimize and improve.
