Distributed intelligent hierarchical system for heat metering and controlling

A key factor of rational energy consumption management is the accurate measurement. Measuring and charging heat consumption are rarely worked out in the prevalent warm-water heating systems. The developed modern heat-meter device, which includes micro-controller, is self-calibrating and self-testing. It uses several correction algorithms in order to increase accuracy after authentication. The discrete devices are connected to a local concentrator via M-bus. The concentrator collects calculated data from measured values and information about the state of the heat-meter. Consumption data and information about the work-state events are logged and stored by the measuring unit. The concentrator is connected to the central supervisory system through mobile communication channel (GSM). In this system, the meter devices respond to arising failures on the one hand with the help of their own algorithms, on the other hand based on information from the concentrator and from the center. The center is able to collect information about measuring and usage, based on requested information. This solution highly increases the speed and the accuracy of the system.
