Aiming at the problems of heating measurement data remote acquisition and short range measuring nodes deployment in building energy consumption monitoring system, the integration technology of ISM wireless network and 4G network is applied in the process of heat metering data acquisition and processing. With the research on effective ISM networking mode and 4G network data transmission technology, a remote wireless heat metering system was constructed and a data acquisition platform based on cloud server was established. By using ISM network, heat data acquisition for metering nodes can be flexible and the cost of wire laying can be reduced. With 4G network and TCP/IP cloud server technology, real-time optimization management of heat metering data can be effectively implemented. The system also provides a solution to multiple terminal data application.
