[Abstract]:With the increasing popularity of cars in China, the problem of parking difficulties in large cities is becoming increasingly prominent. The deployment of parking guidance system is one of the important ways to solve the parking problem. In view of the lack or singleness of guidance information in underground parking lots, this paper studies and designs a parking guidance system, which aims at improving parking efficiency and improving users' experience of time and effort in the past parking process. By studying the current situation of parking guidance system and the actual parking situation in Beijing, the author makes a detailed analysis on the functional requirements of parking guidance system. According to the idea of modular design, the system is divided into three modules: the access control module, the area control module and the parking station status recognition module. Based on the design and implementation of the hardware platform of the induction system, bus communication and image signal transmission technology are applied. Combined with embedded software and upper computer software flow design, the whole operation of the induction system is realized. The hardware design of the system includes the schematic design and implementation of the entrance and exit control module, the area control module and the parking station status recognition module. The entrance and exit control module includes the detection of the ground inductance coil, the gate control, the voice broadcast and 485 communication, the power circuit and so on, which is based on the STC15 single chip computer. The area control module includes multi-computer communication and CAN bus communication circuit with STM32 single chip microcomputer as the core. Parking status recognition module includes ultrasonic parking space detection, traffic light indication, camera image signal transmission circuit and so on. The software design includes the design and implementation of the embedded software flow of the import and exit control module and the design of the software flow of the host computer at the entrance and exit. The design and implementation of the embedded software flow of the area control module and the software flow design of the upper computer in the parking lot. Design and implementation of embedded software flow of parking station status recognition module. It should be pointed out that this paper designs and implements a method of time-sharing and long-distance transmission of multi-channel image signals, which is especially suitable for the image acquisition of every parking space in a large underground parking lot. Parking guidance system is an effective means to achieve fine management. Finally, the author carries on the principle verification and the practical application test to each part of the software and hardware of the induction system. The induction system has been deployed in a large underground parking lot for trial operation. The test results give the statistical data of parking induction time in seconds. The results show that the parking guidance system designed in this paper can guide the parking of large underground parking lots and improve the parking efficiency, and the scale of the system is flexible and flexible.
