摘要
传统舰艇通信数据链传输失效评估方法,存在多链路信息异步数据传输差异化误差过大的问题。从而导致多路通信数据传输时的数据链评估系数与实际传输时效出现偏差,数据链延迟控制准确率降低,铜线数据传输异常。为此,结合数据链的传输分布特征,提出舰艇通信数据链传输时效聚类评估方法研究。首先对聚类评估过程中的时效关系量进行模型量化;然后对其量化模型的聚类评估约束进行定义;最后利用聚类算法对其传输时效进行评估,完成计算。通过与传统评估方法的对比表明:提出的聚类评估方法得到的时效数据与实际传输时效数据之间的误差最小,更适合舰艇的通信数据链传输时效评估。
The traditional failure evaluation method of data chain transmission of ship communication has the large differentiation error of asynchronous data transmission.Therefore,the data chain evaluation coefficient deviates from the actual transmission time,the data chain delay control accuracy is reduced,and the copper wire data transmission is abnormal.Therefore,combined with the transmission distribution characteristics of data chain,the method of ship communication data chain.Firstly,the timeliness relationship in the clustering evaluation process is model quantified;then the clustering evaluation constraints of the quantification model are defined,and finally the clustering algorithm is used to evaluate the transmission duration and complete the calculation.The comparison with the traditional evaluation method shows that the smallest error between the timeliness data and the actual transmission timeliness data is more suitable for the transmission timeliness evaluation of the ship’s communication data chain.
