Groundwater Remote Monitoring Equipment Based On ATmega128

Groundwater is an important water resources, groundwater monitoring is an important basis for the work of water conservancy. At present, groundwater monitor research is still relatively backward, test equipment accuracy is not high, remote transmission of data transmission module missing or reliability is not high, can not meet the needs of modern real-time monitoring. Based on modern computer technology and communication technology, developing high-performance real-time remote monitoring system for groundwater efficient use of groundwater resources in science has important practical significance. This article describes the AVR microcontroller based portable, high accuracy, high reliability water table test electronic equipment-remote monitor groundwater level design and implementation.The main contents of thesis:to Mega128 for the main chip, the design water level remote monitor hardware system, including control module design, the water level data acquisition and conditioning module design, the water level data in the design of digital-analog conversion module, the water level remote data Real-time transmission module design, the power module design. The water level is developed based remote monitoring device and remote PC monitoring system for the performance of each function module environmental suitability testing and field.Data acquisition modules on the test accuracy, reliability of data remote transmission module testing, and equipment for outdoor operation stability of the test, the remote monitoring device with high accuracy, high reliability, monitoring groundwater, to meet the groundwater Monitoring requirements of modern digital information.
