【摘要】：隨著3G/4G無線通信網絡在全國范圍內的普遍使用和商業(yè)運營的成熟,公眾對無線通信的質量和穩(wěn)定要求越來越高。在三大運營商的基站項目合并劃歸鐵塔公司統(tǒng)一管理的背景下,對基站監(jiān)控系統(tǒng)的設計做了分析,研究了基站監(jiān)控系統(tǒng)的數據處理方式和無線傳輸方式的設計與實現(xiàn)。本文設計的監(jiān)控系統(tǒng)重點是采用了基于嵌入式系統(tǒng)的ARM微處理器作為監(jiān)控系統(tǒng)的監(jiān)控前端控制模塊,4G無線網絡通信作為監(jiān)控系統(tǒng)的傳輸通道。本文分析了監(jiān)控系統(tǒng)的需求,對監(jiān)控系統(tǒng)的整體方案進行了分析,分模塊對系統(tǒng)的功能進行了設計,將系統(tǒng)分成三個主要模塊來介紹,包括數據采集模塊、前端控制模塊和網絡傳輸模塊。首先對數據采集模塊,分析了需要采集的數據類型,對不同的數據類型采用了不同的采集方式。其次重點對前端控制模塊進行分析,搭建了嵌入式系統(tǒng)的開發(fā)環(huán)境虛擬機,移植了ARM開發(fā)板的操作系統(tǒng),在ARM開發(fā)板上通過自動化運行程序實現(xiàn)了對數據的預處理,選用實時發(fā)送報警信息數據、定時發(fā)送正常工作數據和監(jiān)控中心查詢之后才發(fā)送數據的方式。最后對網絡傳輸模塊進行介紹,通過4G無線網絡通信的方式實現(xiàn)監(jiān)控前端與監(jiān)控中心服務器的數據通信,采用Nginx和PHP技術在ARM開發(fā)板上進行web-server服務器的搭建,之后開放兩個網絡接口實現(xiàn)數據傳輸和命令接收。該系統(tǒng)通過實驗室環(huán)境和現(xiàn)場各項測試,測試結果表明,通過選用ARM組成前端控制系統(tǒng)的主控單元對數據進行預處理,能夠減少數據的傳輸量,提高數據傳輸的效率。通過采用3G/4G無線網絡傳輸的方式克服了偏遠地區(qū)監(jiān)控系統(tǒng)架設困難的難題。
[Abstract]:With the widespread use of 3G/4G wireless communication network and the maturity of commercial operation, the quality and stability of wireless communication are increasingly required by the public. Under the background that the base station project of the three major operators is merged into the unified management of the Iron Tower Company, the design of the base station monitoring system is analyzed, and the design and implementation of the data processing mode and wireless transmission mode of the base station monitoring system are studied. The emphasis of this paper is to use the ARM microprocessor based on embedded system as the monitoring front-end control module and 4G wireless network communication as the transmission channel of the monitoring system. This paper analyzes the requirements of the monitoring system, analyzes the overall scheme of the monitoring system, designs the functions of the system by modules, and introduces the system into three main modules, including the data acquisition module. Front-end control module and network transmission module. Firstly, the data types needed to be collected are analyzed for the data acquisition module, and different data collection methods are adopted for different data types. Secondly, the front-end control module is analyzed, the virtual machine of embedded system development environment is built, the operating system of ARM development board is transplanted, and the data preprocessing is realized through the automatic running program on the ARM development board. The method of sending alarm information data in real time and sending normal working data and monitoring center inquiry is chosen. Finally, the network transmission module is introduced, the data communication between the monitoring front end and the monitoring center server is realized by 4G wireless network communication, and the web-server is built on the ARM development board using Nginx and PHP technology. After that, two network interfaces are opened to realize data transmission and command receiving. The test results show that the data can be preprocessed by using ARM as the main control unit of the front-end control system, which can reduce the amount of data transmission and improve the efficiency of data transmission. By using 3G/4G wireless network transmission, the difficult problem of remote monitoring system is overcome.
