Flexible GPS/GPRS based System for Parameters Monitoring in the District Heating System
Keywords:Distributed measurement systems, GPS/GPRS, computer data acquisition, low power microcontroller
Energy consumption for heating purposes accounts for a significant part of the budgetsÂ of individual and collective users. This increases the importance of issues relatedÂ to the monitoring of heating energy flows, analysis of flow parameters, verificationÂ of fees and, in the first place, minimization of energy consumption. The goal of thisÂ paper is to develop, by employing Global Positioning System receivers, measurementÂ techniques that are suited to the continuous monitoring of the heating substation parameters.Â This paper presents the design and implementation of GPS/GPRS (GlobalÂ Positioning System/General Packet Radio Service) system for low power data acquisitionÂ using MSP430 Texas Instruments microcontroller for monitoring of the heatingÂ substation parameters. The system is implemented in heating stations for a temperatureÂ and pressure monitoring. It contains GPS/GPRS gateway and 8 analog sensorÂ inputs. Acquisition module and the server base station are suitable for industrial applications,Â home applications and for other appliances. The proposed measurementÂ procedures, which are different from commercially available measurement units, areÂ based on general-purpose acquisition hardware and processing software, thus guaranteeingÂ the possibility of being easily reconfigured and reprogrammed according toÂ the specific requirements of different possible fields of application and to their futureÂ developments.
