Parking Guidance System Research And Practice

SCM courses have the characteristics of highly practical and applied, this paper with parking guidance system based on single chip research and practice in this case for the project, the students realize the project in the course of each module students analyze and solve problems, improve practical ability, the use of project-driven approach in the teaching content, teaching methods, assessment methods related to the three aspects of the research and explorationFirst, give students a background of project development,with the modernization of chinese cities and the continous development of the International process, Urban car ownership increases dramatically, In crowded urban areas where car parking spaces and the contradiction become more and more prominent.the public parking can not be satisfy the increasing parking demand,how to make full use of the limited resources to meet the parking needs,become the problem to need be solved.Then make the project a model to be achieved,parking guidance system Based on MCU,The main purpose is to design and implement an automated parking guidance system..Course of the study is divided into three parts:First of all,this project discusses the parking guidance system's development of domestic and international status,Then it shows the design of this project,the system determine whether there is a car in the parking space by the ultrasonic which is installed above each parking space,and the information is showed by the light above the parking space,next the sensor transports the data to the PC by bus.PC analyzes all the informations and out through the LED display.At the same time the key of this article is identified:ultrasonic detection module design and development.Secondly,we design the hardware circuit,system circuit is divided into two parts, sensors and PC.This project uses the ultrasonic probe and MCU to achieve the distance function,via RS323 to connect PC with the MCU,Ultrasonic detection using HC-SR04 Ultrasonic Ranging Module.Finally, we design and achieve software part,system software is a program written based on micro controller,the core of the program is the MCU controling the ultrasound to transmit and receive signal. At the same time processes the received signal.Obtained the information if there is a car on the parking space. at the same time,we design the system data transfer part of the process for the system scalability,it not only need to transmit data,it also need to check the transmission of the data,we use the vertical and horizontal parity check method to ensure the accuracy of the data transmission.Parking guidance system to drive the project for the teaching content of teaching can combine theory and practice together, the process is a completion of the project design, installation, programming, debugging, comprehensive ability students complete the process. It overcomes the shortcomings of traditional teaching mode single chip, truly student-centered teaching, to practice as the center, not only improve student interest in learning, but also to mobilize the enthusiasm of the students.
