【摘要】：能耗管理逐步成为企业管理一项重要内容。能耗管理首先需要能够全面、实时地获取能耗数据,为进一步采取节能措施奠定基础。基于GPRS网络的远程抄表系统借助现场数据采集传输装置(RTU)和GPRS无线通信实现对广域范围内能耗的不间断采集。系统需要实现长时间不间断工作,因此运行可靠性是系统一个非常重要的指标。 本文首先介绍了远程抄表系统的整体结构和组成模块,然后详细分析了GPRS网络的网络特性。GPRS网络具有无连接、网络不稳定等特性,这些特性反映在网络参数会不断变化、服务器无法连接RTU,从而导致网络传输数据丢失。本文在此分析基础上设计了一个简单的应用通信协议和相关通信约定,使得系统即使在出现上述网络通信异常时也能可靠传输数据或者从故障中快速恢复。接着论文通过分析系统的功能需求和非功能需求(硬件资源限制等)设计出系统软件的整体模块结构,然后针对每个模块、具体的功能函数给出了详细的设计实现。最后论文选择了一个重要模块给出了详细的单元测试设计,并且针对本文设计的应用通信协议给出了详细的黑盒测试方法。
[Abstract]:Energy consumption management has gradually become an important part of enterprise management. Energy consumption management first needs to obtain energy consumption data in a comprehensive and real-time manner, which lays the foundation for further energy saving measures. The remote meter reading system based on GPRS network realizes the continuous acquisition of wide area energy consumption with the help of (RTU) and GPRS wireless communication devices. The system needs to work continuously for a long time, so the operational reliability is a very important index of the system. This paper first introduces the whole structure and component module of remote meter reading system, then analyzes the network characteristics of GPRS network in detail. The GPRS network has the characteristics of no connection and unstable network, which are reflected in the network parameters will be constantly changing. The server was unable to connect to RTU, resulting in loss of network transmission data. Based on this analysis, a simple application communication protocol and related communication protocol are designed in this paper, so that the system can transmit data reliably or recover quickly from the fault even if the above network communication exception occurs. Then the whole module structure of the system software is designed by analyzing the functional and non-functional requirements of the system (hardware resource limitation etc.) and then the detailed design and implementation of the specific function are given for each module. At last, an important module is selected to give the detailed unit test design, and a detailed black box test method is given for the application communication protocol designed in this paper.
