Research on Optimization Simulation of Road Multi-channel Bidirectional Signal Transmission Speed

对道路多通道双向信号传输速度进行优化,可有效提高道路信号传输的效率。实际道路多通道传输受到光强分布不均的影响,导致无法保证快速传输信号。传统方法未考虑信号的分布统计特性极易影响信号输入输出特性,导致其传输速度慢,节点负载均衡度较差,数据丢包现象严重等问题。提出一种基于随机谐波和噪声改善的道路多通道双向信号传输速度优化方法,根据信号在道路多通道中传输时散射光收集特性和光电转换特定,确定信号分布统计特性以及信号输入输出特性,构建信号在道路多通道进行双向传输的模型,并根据信号传输过程中随机谐波和噪声分布概率,对道路多通道双向信号传输模型进行优化,根据优化后模型,实现道路多通道双向信号优化传输。实验结果表明,所提方法信号传输的速度较快,且信号传输过程中,节点的负载均衡度较高,信号中数据的丢包率较低,可实现道路多通道双向信号传输速度优化的目的。

Traditionally, methods are easy to cause the slow transmission rate, poor load balance of node and serious data packet loss. In this paper, a method for optimizing the transmission rate of multi-channel bidirectional signal based on the random harmonics and improvement of noise was presented. According to the characteristic of scattered light collection and the light-transfer characteristic of signal during the road multi-channel transmission, the statistical characteristic of signal distribution and the characteristic of signal input and output were determined. Then, the model of bidirectional signal transmission of road multi-channel was constructed. Based on the probability of random harmonic and noise distribution in the process of signal transmission, the bi-directional signal transmission model of road multi-channel was optimized. On the basis of the optimized model, multi-channel bi-directional signal transmission was achieved. Simulation results show that the proposed method has high signal transmission rate, and the node has high load balance during signal transmission. Meanwhile, it has low packet loss rate of data in the signal, which can achieve the optimization of transmission rate of multi-channel bidirectional signal.
