摘要
Abstract
In smart home temperature control system,when environment temperature fluctuates slightly,it is inadvisable for temperature control system to adopt traditional time⁃triggered mode,since latency and packet loss are apt to deteriorate due to severe channel competition and a waste of node energy is inevitable. In order to solve the problem,a novel temperature con⁃trol system based on event⁃triggered mechanism is proposed. temperature is sampled periodically by wireless sensing node. Ac⁃cording to triggering condition,event⁃trigger determines whether the current sample should be transmitted or not. When actuator node receives new sample value,the control law is updated with random mutation particle swarm algorithm. Simulation shows that,on the premise that input state is stable and meets control requirement,compared with time⁃triggered mode,less samples are needed to be transmitted when using event⁃triggered mechanism,which brings convenience to application of resource⁃con⁃strained wireless sensor and actuator network in smart home.关键词
