Design Of Vehicle Guidance System Based On Piezoelectric Sensor

With the rapid development of China’s economy and the continuous improvement of people’s living standards,the demand for private cars is increasing,which puts forward a new challenge to the construction of urban infrastructure.In order to meet the needs of social development.This requires the design of a high-performance intelligent parking management system,so that the management of the parking lot can be remote and convenient intelligent management.To solve all kinds of problems caused by parking problems.Intelligent parking management,will improve the image of the company o r enterprise,and improve the company’s economic benefits.Especially for large parking lots,it is very important to design an intelligent management system.At present,the mainstream of the detection technology of the parking lot at home and abroad is the detection technology of the ground sense coil.The detection technology has convenient operation,high accuracy,high reliability and low cost.But it also has some shortcomings,such as installation,trouble must be embedded into the road,the measurement accuracy is easily affected by the surrounding environment,the use of sensors to detect vehicles is relatively complicated,too many restrictions.Other common parking space detection technology,infrared detection technology,ultrasonic testing te chnology,etc.Either vulnerable to the impact of the surrounding environmental factors,or because of the cost of the reasons for a large number of input use is not realistic.This paper presents a piezoelectric sensor based vehicle distribution counting device.Solve the problem of large public parking lots on how to get the number of parking and the distribution of vehicles and other issues,and the use of RFID technology in the parking lot entrances and exits,to facilitate the parking of vehicles.The device takes the pressure generated by the vehicle storage in the parking space as the detection signal,MCU receives all regions of the piezoelectric sensor input signal and store high and low to determine the number of parking the vehicle.The device can al so realize the visual analysis of the distribution of the vehicle.When a vehicle storage into parking spaces,the piezoelectric sensor will produce piezoelectric signal,after amplification and detection,input to the microcontroller processing.Finally,o n the LCD screen display parking parking specific distribution.This design through the Proteus software circuit design,build the circuit platform to achieve system simulation.A convenient,efficient and inexpensive vehicle distribution counting device is adopted to realize the counting function of the vehicle.This design detailed introduces the design of the vehicle distribution counting device,hardware design and software design.The device has the advantages of stable operation,convenient insta llation,reliable operation and convenient management,and has high application value and wide application prospect for large scale and complex parking places.
