摘要
导航信息系统硬件在使用无线通信技术进行信息传输时,硬件电路产生寄生电容,导致最终得到的舰船姿态角误差过大,针对这一不足,设计一种无线通信技术的舰船导航信息系统。硬件部分设计惯性导航平台,将PCB板时钟电路与单片机的时钟引脚相连,控制寄生电容大小,设计连接硬件元件电路。软件部分,计算舰船位置导航信息,设定舰船无线通信模式,完成舰船导航信息系统的设计。搭建实验环境,以硬件元件控制的导航信息为实验对象,采用2种传统信息系统与文中设计的信息系统对比,结果表明,文中设计的信息系统得到的姿态角误差最小。
When the navigation information system hardware uses the wireless communication technology for information transmission, the hardware circuit produces parasitic capacitance, which leads to the final error of the ship attitude angle.In view of this deficiency, a ship navigation information system based on wireless communication technology is designed. In the hardware part, the inertial navigation platform is designed. The PCB board connects the clock circuit with the clock pin of the microcontroller to control the parasitic capacitance, and designs the circuit connecting the hardware components. In the software part, calculate the position navigation information of the ship, set the wireless communication mode of the ship, and complete the design of the ship navigation information system. The experimental environment is set up, and the navigation information controlled by hardware components is taken as the experimental object. Two traditional information systems are compared with the information system designed in this paper. The results show that the attitude angle error of the information system designed in this paper is the smallest.
