可穿戴电子设备通信终端自适应负载均衡系统设计

Design of adaptive load balancing system for wearable electronic device communication terminal

当前使用的通信终端负载均衡系统因缺乏移动性和自主性,无法在动态环境中达到稳定通信的效果,为了解决该问题,设计了可穿戴电子设备通信终端自适应负载均衡系统。使用虚拟化服务器,将物理服务器虚拟成若干个服务实例,获得控制权限。利用编码器信号采集装置采集编码器信号,设计负载均衡硬件设备。通过探针监测、接收和计时触发模块,获取反馈的采集指令。计算等待响应的请求百分比,根据负载均衡处理需求判断结果,计算负载信息更新数量,设计负载信息更新流程,完成通信终端的负载均衡处理。由实验结果可知,该系统在静态环境下的2段号提取时间比实际时间少30 ms,在动态环境下的1段号提取时间比实际时间少14 ms,能够达到稳定通信的效果。

Due to the lack of mobility and autonomy,the current communication terminal load balancing system can’t achieve the effect of stable communication in a dynamic environment. In order to solve this problem,an adaptive load balancing system for communication terminals of wearable electronic devices is designed. Use the virtualized server to virtualize the physical server into several service instances to obtain control permissions. The encoder signal acquisition device is used to collect the encoder signal,and the load balancing hardware equipment is designed. The feedback acquisition instruction is obtained through the probe monitoring,receiving and timing trigger module. Calculate the percentage of requests waiting for response,calculate the number of load information updates according to the judgment results of load balancing processing requirements,design the load information update process,and complete the load balancing processing of the communication terminal. The experimental results show that the2-segment number extraction time of the system in the static environment is 30 ms less than the actual time,and the 1-segment number extraction time in the dynamic environment is 14 ms less than the actual time,which can achieve the effect of stable communication.
