Study Of Smart Low Power Loss Heating Detection System

For a long time, the charge for heat in the most northern region depended on residence area in our country in winter, resulting in user's poor energy-saving consciousness and a waste of resources. With the implementation of a series of state energy-saving measures, the charge for heat according to actual quantity is necessary. The Imports Calorimeter is so expensive and the demand of calorimeter in our country is so great that developing a low-cost and match international standards calorimeter is a pressing problem. To this situation, this paper based on the principle of heat measurement, analyze a variety of calorimeter on market and compare their advantage and disadvantage, then design a kind of low-loss thermal measurement system which newly has a temperature control function and a wireless data transmission function.In the guidance of teachers and with the help of students, I completed the low-power intelligent Calorimeter design and development task after more than one year efforts. This system is mainly consists of temperature measurement circuit, flow measurement circuit, room temperature controlling circuit, wireless transmitting circuit and singlechip control circuit.In addition, I also added a temperature control unit and made this system has a function of regulating room temperature. In the data collection, because of the cable technology's shortcomings such as the complex structures, the high cost and the tedious maintenance, we decided to use wireless technology.In the choice of wireless transmission modes, I take into account the high cost of GPRS, infrared transmission's strong directional and short distance of Bluetooth. Final, based on the low-cost MSP430F149 singlechip and low-loss RF chip CC1000, developed the wireless data collection system, and it reached the design requirements.The calorimeter is a crucial equipment to boost the charge according to heat. It measures and charges on the basis of the users consumption of heat actually which had been widely accepted. The heat and cost are associated so the user's energy-saving awareness are enhanced. The administration adopt calorimeter to measure heat that not only facilitates the users, but easy to manage.
