摘要
为进一步提高低压配电网中电表与集中器之间信息的传输效率,将网络编码(Network Coding,NC)应用于电力线载波通信中。结合配电网信道特性对RA码的BP译码算法初始值进行修正,并利用3时隙网络编码通信方式在中继节点对信息进行处理,然后通过广播来实现载波通信信息的传递。仿真和测量结果表明,在电力线信道中经过网络编码后的载波抄表成功率高于传统中继通信方式,而在广播应用之后的网络编码方式抄表成功率显著高于传统中继通信方式,对电力线载波通信具有重要理论和参考价值。
To further improve the information transfer efficiency of meter and concentrator in low-voltage distribution network,network coding is applied in the power line carrier communication.This passage modifies the initial valve of BP decoding algorithm combined with distribution network characteristics,and uses the three timeslot network coding to deal with the received information in the relay node,making the information transmit through broadcasting.The simulation and measurement results show that network coding has a better performance than the traditional relay communication.Furthermore,with the help of broadcasting it gets a far better performance than the traditional relay communication,which has an important theory and reference value for power line communication.
