The Wireless And Intelligent Monitoring System Of Expressway Based On RFID Technology

As the economic artery, expressway has great action, with the development of national economy. To some extent, the expressway utilization is proportional to the growth of our economy. Compared with the common road, the express design stands with a high, traffic big and fast driving characteristics, the level of the current design of the intelligent monitoring system is low. The driver who drives the vehicle can not communicate to the monitoring center. The single means of monitoring due to the low utilization and high accident.In order to improve the efficiency and the safety of expressway, the expressway needs the advanced monitoring system. The article raised the new idea that use the RFID technology in the intelligent monitoring system of the expressway for real-time supervision of the vehicles which entered the expressway in whole course, forms 10 multi-functional modern intelligent monitoring system, for example exchanging data and the prompt between the monitoring center and driver.This paper carried out a detailed particular design of the device on vehicle, the core of the wireless and intelligent monitoring of the expressway. By analyzing the RFID, GPRS, voice, display, clock and other related technologies which the system needs, choosing the appropriate modules and chips, accomplishing the object which reading tag by RFID reader and building the remote network by GPRS technology. The device of the intelligent monitoring system of the expressway transmit the collected data to the monitoring center via GPRS/GSM network,and the monitoring center also can prompt the important information back to the device on vehicle for the driver by GPRS/GSM network. The intelligent monitoring system actualizes the aim of monitoring the expressway and vehicles which entered the expressway by exchanging data between the monitoring center and the device on vehicle.
