摘要
电力线载波通信可靠性是制约其广泛应用最重要的一个因素。该文从通信可靠性的角度,论述了电力线载波通信组网的特点和方法,分析了自动组网的必要性,提出适用于低压配电网电力线载波通信的类蚁群算法(like-antcolonyalgorithm),给出自动路由协议框架,并建立了自动路由模型。通过该模型,可以动态识别低压配电网信道质量,并根据信道质量变化,动态维护电力线载波通信网络路由,保证通信网络的有效性,为建立控制类网络提供一种简单有效的组网方法。仿真和试验研究表明,该方法可以有效延长电力载波通信距离和提供系统通信的可靠性。
The reliability (PLC) is the most important of Power Line Communication one of the factors that limit the application of PLC in practice seriously. The specialties and the methods of building up the PLC networks are discussed in the view of communication reliability, and the necessity of routing automatically is analyzed simply. A kind of ant colony algorithms named Like-Ant Colony Algorithm (LACA) is put forward, which is applicable for communicating in low-voltage networks, and the frame of automatic routing protocol and the relative automatic route model are given. With this model, the quality of channels can be identified real-time, and the dynamic route tables of PLC nodes can be modified to keep the available state of communication as following the change of channel quality, and an effective method of searching the optimum route for PLC is presented for building up general controlling networks. The emulation and the experimentation indicate that the LACA is a simple and effective method of extending the distance and improving the reliability of PLC.
