Abstract:

In view of the difficulty of heat fee collection and unreasonable billing by area,a new type of intelligent meter and its accompanying remote automatic meter reading system is designed in this paper.The entire system is composed of warm air measuring appliance,data transmission system and PC.Through real-time measurement of voltage difference of Pt1000 bridge ends by the heat meter,it calculates the temperature by counting the Hall flowing meter.It obtains the flow value of the users in a short period of time by virtue of the final application of flow and heat.The amount of heat value measurement data can be passed through the CAN bus to the PC,whose management system processes the data.Testing shows that this scheme can achieve intelligent measurement of heat fee in communities.

Key words: billing heat;Pt1000;Hall flow meter
