Intelligent Heat Meter of Monitoring and Controlling System for Heating Supply Based on GPRS Network

Abstract:

In order to realize long-range real-time online monitor and control of the measured data on the spot, and bring about control consumption of heat-energy according to need, a heat meter is developed for heating supply based on GPRS network technology. Low-power single-chip microcomputer MSP430FW427 is adopted as the measuring instruments in which SIEMENS MC55 module was used as a GPRS communication and LC oscillator coupling technology as flow sensor. In addition, the measurement principle of the heat quantity, the design methods of the software and hardware for heat meter are explained in detail, and the mathematical models of temperature and liquid sensor are established in the paper. Application of GPRS communication technology provides a transparent data transmission channel, thus realizing real-time data exchange between fared knots and monitoring center. On-the-spot operations prove that when the system is in real operation, data transmission rate is about 61.8kbps, thus having more advantages of security，accuracy and data transmission rate, effectively solving the problem of a large number of investment on traditional remote monitoring and control system.
