摘要：

将传统多频段信号源切换控制算法应用在分布式通信网络当中无法实现稳定的信号源切换，为此提出多频段信号源远程切换控制算法。利用通信网络监控设备采样实时信号，并计算传输信号的所处频段。以通信信号的传输路径为基础实现对多频段信号源的定位。安装远程控制设备并在其中设置切换控制的触发条件，最终通过切换接入点排序和电压与电流转换控制两个步骤，实现多频段信号源的远程切换控制。为验证远程切换控制算法的可行性，分别从控制抗阻塞性能和稳定性能两个方面实现测试，从而得出测试结论:远程切换控制算法比传统切换控制算法的抗阻塞性能提高了2.2%，且切换控制稳定性能更高。

Abstract:

The traditional multi-band signal source switching control algorithm can not achieve stable signal source switching in distributed communication network. To solve this problem, a remote switching control algorithm of multi-band signal source is proposed. The real-time signal is sampled by communication network monitoring equipment and the frequency band is calculated. Based on the transmission path of communication signal, the location of multi-frequency signal source is realized. The remote control equipment is installed and the trigger condition of switching control is set in it. Finally, the remote switching control of multi-frequency signal source is realized by switching the sequence of access points and the conversion control between voltage and current. In order to verify the feasibility of the designed remote handoff control algorithm, the anti-blocking performance and stability performance of the control were tested. The results show that the anti-blocking performance of the designed remote handoff control algorithm is 2.2% higher than that of the traditional handoff control algorithm, and the handoff control stability is higher.

Key words: distributed network, communication network, multi-band signal source, the remote control, switch control, switching the trigger condition
