一种无线多点远程监控系统的设计与实现

Design of Wireless Multi-Spots Long-Distance Supervisory Systems

为了解决内河航标船发生碰撞实时远程监控的问题,笔者利用超声波雷达测距技术和远距离无线数据传输技术,结合基于轮询机制的点到多点的通信协议,设计了一种包括多个远端模块和一个中心模块的点对多点的无线数据通信系统。此套系统能即时检测船只发生的碰撞,并在中心机房的PC上实时显示状态以及声光报警。目前此套系统已经在某内河航标船上得到实际应用,取得了良好的效果。此外该系统经过较小的修改可适用于其他实时性要求较高、数据量不大的应用。

In order to solve the problem of monitoring collisions of the inland river navigation aid ship, uses the ultrasonic wave radar and the long-distance range wireless data transmission technology. Also with the round inquires based on communication protocol, designed one kind of spot to the multi - spots wireless data communication system, this set of systems could immediately examine the collision when the ships occurred, and the messages as well as the sound and light alarms will be showed on PC at control room. At present this set of systems have already deployed in some inland river navigation ships, and obtained the good effect. In addition this system with smaller revision is also suitable for other timely highly relative requests and small data quantity application.
