Abstract
At present, China's ongoing heating system, the great demand for heat meters. As China's rapid development of urban construction, the city's water, electricity, gas and heating form of management fees and the issue has become more prominent, the paper design of a smart Based on MSP430 heat meters.
The technological level of China-made heat meters is still quite low, and test the accuracy and reliability of foreign products is still a considerable gap. In this paper, the current charge of domestic reform measures of the urgent need for heat meters of the status quo, the analysis of heat meters on the basis of principle, from the traffic detection, temperature detection and low-power design of the three aspects of design improvements, a design Intelligent heat meters.
This paper first introduced the background and development of heat meters significance, given the related concept of heat meters, gave a briefing on MSP430F147 MCU principle and performance, followed by the heat meters in all major hardware components (the main control unit, Flowmeter, matching temperature sensors, etc.) have carried out a comparative analysis of each of the major circuit and a detailed explanation. On the software side, the paper of the system design process flow chart for the overall design, and each of the major parts such as the flow measurement and temperature measurement, and other parts of the flow chart of a note, complete software design.
Key words: MSP430; low power consumption; RS485 communications
