摘　　要：给出了基于G SM/GPRS的海上导航灯标信息的远程监测系统设计方案。系统主要由海上导航灯标现场检测子系统和陆上信息中转子系统两部分组成。考虑到系统的通用性,信息中转子系统还设计了标准的M ODBU S协议,可以很容易地和任何装有M ODBU S协议的监管设备进行通讯。现场检测子系统和信息中转子系统之间以G SM短信方式实现信息和指令交换,信息中转子系统和监管设备之间以标准的M ODBU S协议进行通讯。监管设备一方面可对任一导航灯标进行设置,另一方面也可通过现场检测子系统的“定时发送”和“遇变则报”两种方式实现对多个导航灯标的信息进行轮回和实时的检测。在通讯方面,重点介绍了基于G SM的通讯协议设计方法。经现场调试运行,证明了方案的可行性。It presents a design scheme of GSM/GPRS based remote monitoring system for navigational light buoys. The system is mainly composed of two parts, i. e. , the automatic-measurement sub-systems placed together with light buoys and the information transfer sub-system located on the land used for data receiving and command sending. A standard MODBUS communication protocol is added in the information transfer sub-system,which makes it easy to communicate with any control center in which MODBUS protocol is installed. The information exchange among the measurement sub-systems and the transfer sub system is realized by using GSM. The communication between the transfer sub-system and the control center is through MODBUS protocol. The control center can on the one hand set the commands to each measurement sub system, and can on the other hand get the real time and periodical data of each navigational light buoy. With respect to the communication, it focuses on the design method of GSM communication protocol. It shows that the scheme presented is feasible through lots of tests.
