Design of Temperature Measured Terminal with GPRS in the Central Heating Room and Research of the Charging Method by Indoor Temperature Measured

The paper explores a new method of the heating measurement and charging in the central heating system. The method is different from mechanical heat metering and ultrasonic heat metering existing now. However, by measuring the indoor temperature and recording the temperature periodically during the heating period, and upload the data which are measured and stored in the terminal periodically to the Internet serve by GPRS. It can adjust the charging according to the actual indoor temperature which is transmitted by the terminal. Finally not only can the system meet the requirements of the users in the heating period, but also achieve the building energy efficiency. Adhere to people-oriented principle. Make the service of heating become more and more humanized.
