Design And Application Based On PIC Of Remote Terminal Monitoring System On Regimen

With the increasing number of mountain flood and hydrological aspects of droughtand other natural disasters, has posed a major threat to the rapid development of thenational economy, so it is very important to the regulation of the water regime.Hydrological monitoring is an important part of the regulation of the water regime, isan opportunity, a challenge.The situation of our country in various fields, more pointsneed to be monitored, the relatively wide range of distribution, and variousmonitoring points also relatively concentrated between distant. The combination ofthese forms and the development trend, this paper presents a hydrologic remotetelemetry terminal monitoring system design based on the PIC, a telemetry terminalsplaced at each monitoring point telemetry terminal via GPRS wireless communicationthe data sent to the internet, the internet and then send the data to a web server. Thisnot only solves the difficult problems of data acquisition of the various monitoringpoints, and also reduce the cost of system operation and maintenance.This paper describes the current situation of domestic and foreign telemetryterminal and a combination of Hefei Dong Da reservoir water remote terminal controlsystem components and overall design. Described in detail based on thehigh-performance, low-power microcontroller PIC telemetry the terminal hardwaredevelopment and software design, terminal hardware section includes the controllercore minimum system, external sensor, sensor interface circuits, realize wirelesscommunication connection with GPRS DTU the interface circuit is currentlydisplayed data, and set the parameters of the liquid crystal panel and the interfacecircuit; software design is based on the hardware circuits developed on the basis of thecompile environment is based on the PIC microcontroller MPLAB against the watertelemetry terminal required to achieve the functions by programming the andhardware board function block workflow water remote terminal functions. Thesoftware design is completed through the after microcontroller burning mouth burning,the water remote terminals will be reached by the effect of the pre-development.Finally, the monitoring system consisting of water telemetry terminal testingprocess, the system including terminals, solar panels, batteries, charge controller,GPRS DTU, etc.. The test consists of serial testing and monitoring in two ways in thehost software, and the data obtained according to the two test methods to analyze theperformance of the system, it also describes the enlarge of the system performancecan be achieved for oil, electricity, mine, for thermal station unattended monitoringstations, has a broad application space and good prospects.
