Study Of Groundwater Detector Based On MSP430

China is a populous country, although the total water resources are abundant, but water resources per capita is far lower than the world average, in China's existing water resources, groundwater resources dominant. But affected by industrial development and some of the illegal enterprise underground drainage, to the groundwater pollution, appear many such as salt, water erosion and sedimentation of groundwater problems. Therefore, the temperature of groundwater, water level, PH value, PH, turbidity, the monitoring of parameters such as conductivity has become the top priority. This topic focuses on the domestic and foreign relevant detector's development present situation and the actual demand of groundwater, the groundwater temperature detection, water level detection, turbidity, etc, are studied, is committed to developing a resolution of 0.01 ? high precision in temperature detection intelligent monitor groundwater.In this paper, based on the research status at home and abroad, with MSP430 as the main controller and formulated a series of control scheme. According to the practical application, to determine the test parameters using the sensor, detection methods.In the aspect of hardware, the system divided into two parts, lower place machine and superordination machine. Under a machine according to temperature, water level and turbidity designed separate signal measurement and signal processing circuit, sensor will eventually induced by the signal processing circuit is converted into a physical signal data sent to the single-chip microcomputer, after processing to send digital tube display, at the same time through wireless radio frequency module for wireless transmission parameters of groundwater. PC via wireless receiving module and the next bit machine communication, finish on groundwater hydrology data for processing and storage. If the collected data and system setting data difference is too big, then start alarm circuit.In the aspect of software design, through the C language to achieve single-chip microcomputer to collect data receiving, processing, display and storage, by PC interface, realize the groundwater quality, according to terminal monitoring data and using software to complete the image analysis of measured data.This topic through the development of the detector of groundwater, can realize to the groundwater temperature, water level and the parameters of the turbidity of real-time monitoring, can quickly reflect the water quality of the groundwater, make a reference for groundwater quality assessment.
