【摘要】：电力载波通信技术是指应用载波调制/解调技术使信号在电力线上进行传输的技术。近年来,随着物联网、智能家居及智能楼宇的发展,以及在电力线上进行高速数据传输技术的突破,再加上现有的比较完善的电力线网作支撑,使得电力载波通信技术越来越多的被应用于通信领域。本文在电力线载波模块的基础上,提出了一种更加适合低压电力线载波通信网络的组网路由方案,并将软件设计方案应用到硬件平台进行了测试,证明其在智能家居的家庭安全和健康监护方面可以发挥很好的作用。系统设备可应用于智能小区,楼宇范围内,以满足项目可适合更多场景应用的需求。本文共分为以下几个部分:(1)组网部分,根据电力线载波通信的特点,以树状结构为组网基础,提出了一种改进的组网路由方案,采用一主多从的方式,通过子节点对主节点轮流应答以及下层网络的随机延时应答机制,完成组网,并在NS2模拟器中通过模拟家庭网络结构对组网算法进行了性能仿真,证明其通信的可靠性;(2)采用STM32为基本控制模块,采用串口通信的控制方式,与电力线载波模块相连,以达到连接电力线的功能;(3)采用安卓系统制作控制界面,通过手机与硬件相连,实现组网中的各个节点的监控。整个系统的物理连接全部通过电力线,不需要额外的线路,能够节省通信成本;通过智能家居系统,不仅可以监测家庭的温度和气体浓度等,还可以实现监控家庭安全的自动提醒。
[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.
