摘要
随着海上运输业的不断发展,关于港口运输交通的研究日益增加。在原有智能港口运输交通流模拟系统使用过程,常因模拟结果误差较大,造成港口交通研究结果可靠性较差的问题。因而,设计线性模型下智能港口运输交通流模拟系统。硬件方面,安装船载GPS收发装置,设定系统控制器,其他硬件部分沿用原有设备。引用线性模型优化交通流模拟计算法,构建高精度智能港口运输交通流模拟模型,提升系统的模拟精度。至此,线性模型下智能港口运输交通流模拟系统设计完成。通过系统测试对比可知,此系统的模拟结果误差数值低于原有系统模拟结果误差数值。综上可知,线性模型下智能港口运输交通流模拟系统模拟精度较高。
With the continuous development of maritime transportation, the research on port transportation is increasing. In the process of using the original intelligent port traffic flow simulation system, the reliability of port traffic research results is often poor due to the large error of simulation results. Therefore, the traffic flow simulation system of intelligent port transportation under linear model is designed. In terms of hardware, install GPS transceiver on board, set system controller, and use the original equipment for other hardware parts. By using the linear model to optimize the traffic flow simulation calculation method, a high-precision intelligent port traffic flow simulation model is constructed to improve the simulation accuracy of the system. So far, the design of intelligent port transportation traffic flow simulation system under linear model is completed. Through the comparison of the system tests, it can be seen that the error value of the simulation results of this system is lower than that of the original system. In conclusion, the simulation accuracy of the intelligent port transportation traffic flow simulation system under the linear model is high.
