某型水下航行体北斗状态实时监控系统

Real time monitoring system for Beidou status of an underwater vehicle

针对某型水下航行体内部北斗偶发性工作异常问题,设计一种独立的航行体内部北斗状态实时监控系统,对航行体当前北斗工作状态相关参数进行连续测量和实时解算,并依据相关判断准则进行临时介入性操控,提高北斗通信及定位有效率,从而提高航行体的实航安全性和可靠性。该系统设计中充分考虑航行体内部结构及工作环境,在兼顾原总线协议、控制条件及控制流程等相关要求基础上,摒弃常用的隔离、开关等大尺寸、高功耗元件组建方法,采用小尺寸、低功耗的组合集成式设计方案,实现某型水下航行体北斗状态的实时监控功能。该监控系统通过环境试验和电磁兼容性等相关测试,并在国内某水域搭载某型水下航行体完成实航试验测试,试验结果表明该监控系统可在航行体北斗工作异常时介入操控,提高航行体实航安全性和可靠性。

Aiming at the accidental abnormal operation of Beidou in an underwater vehicle,an independent real-time monitoring system of Beidou status is designed,which continuously measures and calculates the relevant parameters of the current Beidou status of the vehicle,and carries out temporary intervention control according to the relevant judgment criteria,so as to improve the efficiency of Beidou communication and positioning,so as to improve the navigation performance of the vehicle safety and reliability.In the design of the system,the internal structure and working environment of the vehicle are fully considered.On the basis of considering the original bus protocol,control conditions and control flow and other related requirements,the commonly used large-size and high-power components such as isolation and switch are abandoned,and the small-size and low-power integrated design scheme is adopted to realize the real-time monitoring function of the Beidou state of an underwater vehicle.The monitoring system has passed the environmental test and electromagnetic compatibility test,and carried a certain type of underwater vehicle in a domestic water area to complete the actual navigation test.The test results show that the monitoring system can intervene in the control when the Beidou of the vehicle is abnormal,and improve the navigation safety and reliability of the vehicle.
