【摘要】:能耗管理逐步成為企業(yè)管理一項重要內(nèi)容。能耗管理首先需要能夠全面、實時地獲取能耗數(shù)據(jù),為進一步采取節(jié)能措施奠定基礎;贕PRS網(wǎng)絡的遠程抄表系統(tǒng)借助現(xiàn)場數(shù)據(jù)采集傳輸裝置(RTU)和GPRS無線通信實現(xiàn)對廣域范圍內(nèi)能耗的不間斷采集。系統(tǒng)需要實現(xiàn)長時間不間斷工作,因此運行可靠性是系統(tǒng)一個非常重要的指標。 本文首先介紹了遠程抄表系統(tǒng)的整體結構和組成模塊,然后詳細分析了GPRS網(wǎng)絡的網(wǎng)絡特性。GPRS網(wǎng)絡具有無連接、網(wǎng)絡不穩(wěn)定等特性,這些特性反映在網(wǎng)絡參數(shù)會不斷變化、服務器無法連接RTU,從而導致網(wǎng)絡傳輸數(shù)據(jù)丟失。本文在此分析基礎上設計了一個簡單的應用通信協(xié)議和相關通信約定,使得系統(tǒng)即使在出現(xiàn)上述網(wǎng)絡通信異常時也能可靠傳輸數(shù)據(jù)或者從故障中快速恢復。接著論文通過分析系統(tǒng)的功能需求和非功能需求(硬件資源限制等)設計出系統(tǒng)軟件的整體模塊結構,然后針對每個模塊、具體的功能函數(shù)給出了詳細的設計實現(xiàn)。最后論文選擇了一個重要模塊給出了詳細的單元測試設計,并且針對本文設計的應用通信協(xié)議給出了詳細的黑盒測試方法。
[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.
