基于3G技术的船舶远程监测系统

Remote monitoring system basis on 3G for ships

目前常规的基于GSM和GPRS的无线通信技术由于其传输速度问题,在内河船舶远程监测上的应用受到限制。结合正在推广的3G技术,将其很好地应用到船舶的远程监控系统中,解决了目前基于GSM和GPRS无线信息传输所存在的传输量不足的缺点。介绍了基于3G的船舶远程监测和故障诊断系统的总体结构、船用TD-SCDMA系统的构成、TD-SCDMA信道的估计、上下行链路容量的估测以及软件的设计,这也使图像和声音这些反映船舶营运状态的重要信息真正应用到船舶远程监测系统中,极大地提高了船舶监测及故障诊断的准确性。

Due to the low transmission speed, common wireless communication technologies such as GSM and GPRS could not be successfully used for river-going ship remote monitoring. This article proposes the use of 3G technology into the remote monitoring system of ship. Remote monitoring and fault diagnosis system based on 3G is introduced in this paper. Structure of marine TD-SCDMA wireless communication system is described, together with the transmission channel estimation, capacity calculation and software design. This technology could overcome the diffieulty of signal transmission in the present wireless communication system based on GSM and GPRS and could also transfer multi-media information including pictures and sounds, which could be used to judge the working condition of maehines on board ship and hence improve the accuracy of remote monitoring and failure diagnosis for river-going ships greatly.
