Design and Application of IC card paid water wells Remote Monitoring System

摘要

Nowadays, the short of water resource has been a problem. To make the use of water resource more effectively, especially the underground water, we designed the IC card paid water wells Remote Monitoring System. The system consists of 3 parts--water wells terminal control unit, the data transmission network and supervisory and trade center. The process includes hardware design and software design. The core point consists of the IC card reading and writing processes and RS485 multi-device communication using MODBUS protocol. After testing, the basic function is completed, and it will be in the future having broad prospects for development in many fields.
