Abstract

At present, most heat network monitoring systems adopt wireless GPRS/CDMA transmission mode, and the data are transmitted back to the information center by the RTU or intelligent instrument of each heat exchange station.The topological structure of the network mostly adopts the star structure. The specific method of transmitting data through the network is very important. APN technology is one of the access modes, which USES the platform of telecom operators to form a private network to achieve the purpose of data monitoring.
