Design and application of data collecting system and data receiving system for water quality monitoring buoy

To obtain stable time series observations at low power consumption, a data acquisition system for water quality monitoring buoy was designed. It includes CPU module, control/protection module, communication positioning module, and interface expansion module. In this data acquisition system, a CF2 mainboard was used as the CPU module, with the assistant of a multi-functional board, which uses a single chip microcomputer as a control unit. All the following functions, such as collecting data, saving data and communication, and expanding the modules to realize counting, I/O control, AD (Analog to Digital) conversion, timing, and other functions can be accomplished. A double “watchdog” was designed for the control/protection module to achieve the entire process of independent work unattended in all-weather conditions. The water quality monitoring data system was designed for the purposes of remote receiving, storing and displaying of water quality monitoring data. It includes four key components: data acquisition module, data processing module, systematic early warning module, and data display module, which have the following advantage characters: easy operation, high degree of automation, and graphical display intuitively easy to read.
