Groundwater Inspecting System Based on Distributed Bus

Nowadays, the pollution of groundwater has become more and more serious. There are many pollution sources such as fuel, garbage, agriculture and industry related wastes. Because of lack of fresh water,groundwater has been over extracted. Therefore, changes of groundwater including quality, quantity, pH, temperature and water level should be monitored. To satisfy this need, we developed groundwater monitoring system based on distributed bus and sensor technology. This system can give us multi-parameter digital display and remote communication. We also used the HTG method in automatic measurement of groundwater quantity. Many other sensors have been used in detecting the other characters of groundwater. We designed a multi-access device to collect the signals from all kinds of sensors. After getting all the parameters, we transmitted these signals back to the computer by RS-485 distributed bus. The application software running on the computer uses the specific algorithm to process all the data, then changes of groundwater are displayed immediately. So the inspectors can know the situation and make corresponding decisions. The practical use shows that the system has satisfactory performance and good application result.
