Abstract

The invention discloses a sensor deployment method and system based on BIM and simulation. The method is based on the information of BIM. In the simulation environment, the sensor data is represented by the indoor environment variable in the divided hot zone, and the environment variable of the hot zone is used. The influence component on the HVAC terminal is used as a decision variable, with the minimum HVAC misadjustment rate and the minimum number of configured sensors as the optimization goals, and a random search algorithm is used to obtain the optimal deployment scheme of indoor sensors. The invention enables the deployment of indoor sensors to be completed at the architectural design stage, which significantly saves the cost of data collection and scheme testing; at the same time, it adopts a clear and adaptable optimization target, making the optimization result more practical.

Description

technical field [0001] The invention belongs to the technical field of building sensor network deployment and HVAC (heating ventilation and air conditioning) system control, and specifically relates to a building sensor network node deployment method and system based on BIM (building information model) and simulation. Background technique [0002] The HVAC system is the main indoor environment control device in a building, and it undertakes most of the indoor human comfort requirements. Especially in today's increasingly serious urban heat island effect, HVAC system has become an indispensable device in every building. In recent years, with the increasing demand for comfort in buildings, intelligent and refined indoor environment control has become more and more important, and the increase in computing power brought about by the advancement of computer technology and information technology has also made The realization of this requirement is more feasible. As a negative fe...
