摘要
水文遥测是为满足防汛抗旱指挥系统建设的要求,进行实时水文监测的自动测报系统。水文监控跨越地域大,监控的作业点分散于野外、环境恶劣、数量多且无人值守。在汛期时要求通讯速率高,轮询响应时间短,传统的水文遥测系统的通信方式已经不能满足水利信息化和防洪抗旱的要求。根据我国水文采集的现状,结合GPRS通信网络的特点,本文研究和设计了基于GPRS的无线水文遥测终端机。
论文首先介绍了水文遥测终端机的设计依据和原则。根据水文遥测终端机的功能,提出了水文遥测终端机的设计内容、外部结构要求和性能指标。
论文设计的水文遥测终端机由水文数据传感器模块、无线通信模块、电源模块和主控制器模块组成。通过系统整体化研究和各模块细化研究,对各模块进行了设计。主控制器模块硬件设计主要以SST89E554RC微控制器为核心,通过外围电路设计实现了各模块间的结合;软件设计以程序开发软件Keil为平台,以实现水文遥测终端机通信和多重功能为目标,对程序进行了模块化设计。通过硬件电路设计和模块化软件流程设计,主控制器模块实现了水文数据的采集、处理、存储、传输等功能。针对水文遥测终端机供电特点,电源模块重点研究了遥测终端机的节电方式,提出了分区供电的电源管理方法和中断激活分时操作的混合工作模式,最大限度的保证系统的电源供给。
论文设计完成了基于GPRS的无线水文遥测终端机,对改善我国水文信息采集的工作效率和工作效果、增强水文信息采集的广域性、实现水文站的无人值守提供了有力的技术支持。
Hydrological telemetry is an automatic system of hydrological monitor to meet request to flood control and drought relief command system. Hydrological monitoring is across large geographical. And monitoring operating points scattered in the wild, bad environment, unattended equipment. In the flood season, the high speed communication and communication is demanded. Traditional communication of Hydrological telemetry system cannot meet the demand of water information and flood control and drought. According to the status of hydrological information sampling and GPRS net characteristic, the scheme of hydrological information sample terminal system based on GPRS is put forward.
The design basis and principles of hydrological telemetry terminal is introduced in this thesis at first. The design elements, external structure demand and performance indicators is put forward according to function of hydrological telemetry terminal.
In this thesis, the hydrological telemetry terminal is composed by Hydrological data sensor module, wireless communication module, power supply module and main controller module. These modules is designed through the whole system research and detailed study. The hardware of main controller module is designed centered on SST89V554RC. And the combination of each module is achieved by external circuit design. The software is designed modular using Keil as platform to achieve the targeting of hydrological telemetry communications and multi-functional terminal. The function like sampling, processing, storing and transmission of hydrological data is realized. For the power supply characteristics of hydrological telemetry terminal, the power-saving mode is focused on in power supply module. The power management method of supply division and the mixed working mode of interrupted activation-timesharing is put forward. The reliable work is ensured maximum.
In this thesis, the system of wireless hydrological data transferring based on GPRS is designed. It helps to improve efficiency and effectiveness, wide-area and the convenience of hydrological signal sampling and provide technical support of realization unattended hydrometric station.
