Fault diagnosis system of heat meter based on VC++

The popularization of heat metering promotes the demands of the remote transmitting system market and heat meter market, which requires higher standards on hot water flow meter management during the using period. Develops a system of hot water flow meter fault diagnosis based on VC++. Adopts multiple-time data longitudinal comparison and single moment data crosswise comparison to solve the problems of unrepresentative and big error using single moment data, and considers the data storage features of different remote transmission system, which provides a good theoretical basis and data support for the heat meter management and charging.
