Analysis of Data Upload Mode in Intelligent Temperature Control System Based on CAN

Energy saving and emission reduction has been the core of the development of the global economy, the focus of people's attention, based on the CAN bus intelligent temperature control system can save building energy consumption, thereby reducing amount of coal, reducing emissions of pollutants. The data of intelligent control system can use two modes, master-slave mode or take the initiative to upload. Through the experiment and analysis, the conclusion is that the time of room temperature decreased one degree is about 40 minutes, when master-slave mode was used, data processing time is not more than 1s, and the master node can according to need to set the idle time, greatly reducing the frequency of data processing, and not timely processing of the data caused economic losses rarely, when active the uploading mode was used, due to mutual interference upload interval is uncertain. Therefore, the energy-efficient heating system of construction using master-slave mode is better.
