Research on Hydrological Environment Monitoring Equipment based on Embedded System

Aiming at the shortcomings of traditional water environment monitoring device, a hydrological environment monitoring equipment based on embedded system is proposed in this thesis. The hydrological parameters information monitored by the equipment mainly includes water turbidity, air particulate concentration, atmospheric pressure data, and so on. These field data of water environment are collected by special sensors, which are driven by an embedded platform based on S3C2440 microprocessor. The embedded platform obtains the monitoring data through the IIC communication protocol. Then, the hydrological environment monitoring data is stored in the embedded database and displayed on the LCD screen of the equipment on site. Furthermore, when the hydrological environment parameters exceed the predetermined monitoring standards, the monitoring information will be sent to users in the way of SMTP based e-mail and alerted automatically by the equipment. The remote users can access the hydrological monitoring equipment remotely and query the real-time monitoring information of the hydrological site in the form of web pages through the network. The test results show that the embedded hydrological environment monitoring equipment proposed in this thesis is convenient for monitoring the main hydrological parameters in time, and can fully meet the design requirements.
