遥测遥控航标的设计.docVIP

摘 要 我国是世界上河流众多的国家之一，数量多，流程长，而且很多河流水域具有重要的航运价值。然而我国许多河流一年之中水位变化频繁，水位发生变化后，指示航标极易偏离初始位置，无法准确指示航道位置，影响航行、人身及财产安全。为了提高航标维护人员的工作效率，降低人工维护成本，遥测遥控无人值守的自动航标系统的研究应用势在必行。 本文主要研究了基于GSM短消息服务功能、GPS定位系统的遥控遥测航标系统的设计与应用。本设计中，采用模块化的设计思想，将整个系统分为控制中心和航标船两个子系统，分别对控制中心的水位监测单元，报警单元和航标船的中心处理单元，供电单元，动力制动单元，GPS定位单元，船体故障检测单元以及连接二者的GSM无线通信单元从方案可行性，到电路设计，再到程序设计作了详细的研究与分析，最终完成了整个的设计。 该系统通过监控中心实时检测河流水位异常信息，通过GSM网络的短信功能，将异常信息发送给航标船。航标船接收异常信息，根据水位信息作出相应的调整，保证船体始终能够正确导航。 关键词：航标船,遥控遥测,GSM,GPS ABSTRACT China is one of the countries that have many of rivers in the world not only the huge number, but also the long process. Many of them have the important value in shaping. However , the level of these rivers changes frequently in a year, making the indicating mark deviates from the initial position highly, so the indicating mark can not indicate the accurate channel position ,probably affecting navigation ,personal and property safety. In order to improve the navigation aid maintenance personnel’s working efficiency and reduce artificial maintenance costs, the research and application of automatic navigation system of remoting unattended is imperative. This paper mainly studies the design and application of remote control and telemetry navigation system of GPS positioning system,based on the GSM short message service function.This design adopts the idea of modular design,and the whole system is divided into the control center and the navigation mark ship two subsystems,this design respectively research on water level monitoring unit of control center, an alarm unit and the central processing unit of the navigation mark ship, power supply unit, dynamic braking unit,GPS positioning unit, The fault detection unit of the ship and the GSM wireless communication unit connected between them,from the feasibility of the scheme, the circuit design, and then to the program design makes a detailed research and analysis, and finally finished the whole design. The system through the control center detects the
