摘要
针对传统船舶通信信道负载调控过程中出现的调控精度低、响应时间长的问题,设计一种基于无线局域网的信道负载调控技术。利用无线网关协议,对信道的载频特征进行分析,在此基础上,确定信道负载状态字的输出格式,将BFP算法作为主帧定义进行信道输出状态的实时控制,实现船舶通信信道的负载调控。通过仿真实验验证了该技术的有效性,结果表明,无线局域网负载调控技术较传统负载调控技术的精度高出了24.78%,且响应时间较为合理,符合理想的信道负载调控标准。
Aiming at the problems of low precision and long response time in load regulation of traditional ship communication channel,a load regulation technology based on wireless local area network(WLAN)is designed.Using the wireless gateway protocol,the carrier frequency characteristics of the channel are analyzed.On this basis,the output format of the channel load state word is determined.The BFP algorithm is used as the definition of the main frame to control the channel output state in real time,so as to realize the load regulation of the ship communication channel.The simulation results show that the accuracy of load control technology in WLAN is 24.78%higher than that of traditional load control technology,and the response time is reasonable,which meets the ideal channel load control standard.
