智能电网是一种新颖的数字化的电气网络,它将电能的生产、配送和控制有机地整合在一起.ZigBee网络由于具有低成本、低功耗、低数据率以及低复杂度等特点,适合应用于智能电网;但是其与无线局域网(WLAN)在同一区域共存将造成ZigBee网络性能的显著下降.针对这一问题,提出了一种多信道的干扰避免策略.通过应用多信道通信的方法,传统的信道切换算法中的“信道切换请求(CSR)的传输受干扰影响”问题得到解决,从而提高了CSR传输的可靠性.实验结果表明,与传统的信道切换算法相比,本文提出的干扰避免策略提高了信道切换的成功率,增强了ZigBee网络在 WLAN 干扰下的可靠性.
Smart Grid is a novel digital electrical network that integrates the production, distribution and control of electrical energy.ZigBee network is suitable for applications due to its low cost, low power consumption, low data rate and low complexity However, its coexistence with wireless local area network (WLAN) in the same area will lead to a significant decrease in the performance of ZigBee network.Aiming at this problem, a multi-channel interference avoidance strategy is proposed.Through the application of multi-channel communication, , The problem of transmission interference affected by channel switching request (CSR) is solved and the reliability of CSR transmission is improved.Experimental results show that compared with the traditional channel switching algorithm, The interference avoidance strategy improves the success rate of channel switching and enhances the reliability of the ZigBee network under WLAN interference.
