Design of building temperature automatic measurement and control based on BIM technology and CAN controller
In order to improve the thermal insulation performance and accuracy of the building temperature automatic measure-ment and control system,this study adopts the temperature collector and monitor of building information technology,combined with the heat flow meter technology,and uses the local area network controller to set the monitor to support a variety of protocols and moni-toring performance.The results show that the system achieves 0.45 W heat transfer coefficient in the measurement of building wall temperature performance,which is better than 0.40 W in the traditional heat flow meter method.In terms of measurement and control time,the system recorded 36.103,which is slightly longer than system C's 13.974,but lower than System B's 37.594,demonstra-ting better prediction accuracy.At the same time,the economic and environmental benefits of the system in the common climate re-gion are better than those in the extreme climate region.The analysis of heat flow difference between thermal bridge and non-thermal bridge area of building wall provides key insight for architectural design and construction.In summary,the system based on building information technology has shown excellent performance in terms of measurement accuracy,contributing key technologies to the pro-gress in the field of building energy efficiency.
