Research On Distributed Network Measurement And Control System Of Smart Home

Smart home systems are mainly divided into wiring systems and wireless network systems.They have the advantages of safety,convenience,and humanity,enabling people to enjoy a comfortable and convenient life.Aiming at the problems of complex switch control,inconvenient operation,centralized control wiring and difficulty in obtaining and monitoring of environmental data in smart home systems,this paper proposes a distributed network consisting of home parameter monitoring network,home switch control network and gateway nodes.Measurement and control system program.The home parameter monitoring network uses ZigBee wireless network to transmit data.It contains up to 100 parameter monitoring nodes.The node is composed of CC2530 controller circuit,power supply circuit,antenna circuit and measurement circuit.It is responsible for obtaining various peripheral environmental parameters.The home switch control network contains a maximum of 100 switch control nodes.The nodes are composed of STM32 controller circuits,power supply circuits,switch circuits,communication circuits,touch circuits,and relay circuits,and are responsible for controlling the connectivity of the electrical or outlet power supplies.The gateway node is responsible for interacting the system data with the server,and the user can remotely monitor and control the home.Aiming at the problem of excessive energy consumption of the classical LEACH protocol algorithm,based on the advantages of LEACH protocol and FCM algorithm,a smart home wireless sensor routing algorithm is proposed.The clustering preprocessing phase is added in the algorithm,and the limiting factors such as the degree of membership,remaining energy,and the base station distance factor are added to the cluster head selection.The data transmission process uses a dynamic transmission mode to solve the problem of inaccuracy of cluster centers and unreasonable selection of cluster heads.Single problem with data transfer mode.Simulation results show that the smart home parameter monitoring node control algorithm can achieve the goal of balancing the energy of the wireless network,reducing the overall consumption of the network,and extending the life span of the network.The distributed network monitoring and control system controls the switch control nodes through the RS485 bus.Several switch control nodes can be configured in an interlock mode.The interlocked switch control nodes can control the functions of one or more electric appliances.The intelligent home parameter monitoring node control algorithm reduces the energy consumption sent and received by the network,and the parameter monitoring node can use a longer time,and the time interval for battery replacement increases.The distributed network monitoring and control system in this paper satisfies the design requirements of the system and provides a feasible implementation scheme for the smart home system.
