[Abstract]:Power carrier communication technology refers to the technology of using carrier modulation / demodulation to transmit signals on the power line. In recent years, with the development of the Internet of things, the development of intelligent home and intelligent buildings, and the breakthrough of high-speed data transmission technology on the electric power line, and the existing more perfect power line network as support, the electric power is made. The carrier communication technology is more and more used in the field of communication. On the basis of the power line carrier module, this paper puts forward a network routing scheme which is more suitable for the low voltage power line carrier communication network, and applies the software design scheme to the hardware platform to test the family security and health monitoring in the smart home. The system equipment can play a very good role. The system equipment can be applied to the intelligent community and the building range to meet the requirements for the application of more scenes. This paper is divided into the following parts: (1) based on the characteristics of the power line carrier communication, an improved network routing scheme is proposed based on the tree structure as the network base. In one main multi slave mode, the network is completed by the sub node's response to the main node and the stochastic delay response mechanism of the lower network. The performance simulation of the network algorithm is carried out through the analog home network structure in the NS2 simulator, and the reliability of the communication is proved. (2) STM32 is used as the basic control module and the serial communication is used. The control mode is connected with the power line carrier module to achieve the function of connecting the power line. (3) the Android system is used to make the control interface and the hardware is connected to the hardware to realize the monitoring of each node in the network. The physical connection of the whole system through the power line, without additional lines, can save the cost of communication; through intelligence. It can not only monitor the temperature and gas concentration of the family, but also automatically monitor the safety of the family.
