Cortex_M3 and GPRS based route identification RFID read-write equipment of highway toll collection system

Abstract

The invention relates to Cortex_M3 and GPRS based route identification RFID read-write equipment of a highway toll collection system, comprising a shell, a computer interface slot, a power input interface, a circuit mainboard, a GPRS module and a radio-frequency RFID module, wherein the computer interface slot and the power input interface are arranged on the surface of the shell; the circuit mainboard is positioned in the shell; the GPRS module is used for the wireless communication between highway vehicles and a control center; the RFID module is used for acquiring the information of the highway vehicles; the GPRS module is connected with a GPRS antenna; and the circuit mainboard comprises a microprocessor which is used for taking charge of receiving card information read by the route identification RFID read-write equipment, stores the card information and transmits the card information to the control center through the GPRS and transmits corresponding site information and instant information to the route identification RFID read-write equipment so that the route identification RFID read-write equipment writes the site information and the instant information in a card. The invention can effectively identify car routes, repeal various toll stations positioned on the middle section of a highway, save a large quantity of manpower resources and management cost and enhance the car running efficiency.

Description

technical field [0001] The invention relates to a high-speed, long-distance reading and writing device based on a Cortex_M3 microprocessor and integrating GPRS networking technology and RFID technology, which is suitable for line identification equipment in a non-stop toll collection system on expressways. Background technique [0002] At present, the construction of expressways in China is developing rapidly, especially in the coastal development areas. It is convenient for the masses. At present, the tolls of the expressway are calculated according to the nearest route by the computer according to the starting point and the destination of the driving. At the same time, the right of way unit cannot carry out the correct distribution of benefits because it cannot confirm the route of the vehicle, which is a problem. The national problem of expressway operation and management for many years - the problem of ambiguous route tolls and splitting. [0003] For example, the Shang...
