【摘要】：直放站是移動網(wǎng)絡(luò)無線系統(tǒng)的一個(gè)重要組成部分，它能覆蓋到移動基站信號較差的地方，擴(kuò)大并加強(qiáng)移動網(wǎng)絡(luò)覆蓋區(qū)域和強(qiáng)度。移動網(wǎng)絡(luò)覆蓋的強(qiáng)弱很大程度取決于直放站監(jiān)控系統(tǒng)的使用，使用它對各監(jiān)測點(diǎn)運(yùn)行情況的數(shù)據(jù)采集。因此，對研究直放站監(jiān)控系統(tǒng)的運(yùn)用具有很大的意義和價(jià)值。而現(xiàn)在我國大多直放站設(shè)備生產(chǎn)廠商是小廠家，生產(chǎn)制造設(shè)備的技術(shù)水平不足，直放站設(shè)備出現(xiàn)故障后一般通過用戶反映才能知道設(shè)備實(shí)際的使用情況，設(shè)備沒有網(wǎng)絡(luò)監(jiān)控，而直放站設(shè)備使用很大一部分都是使用在室內(nèi)、偏遠(yuǎn)山區(qū)一些信號深層覆蓋區(qū)域，處理問題很慢，如沒有監(jiān)控，很難快速解決直放站設(shè)備問題，勢必會嚴(yán)重影響網(wǎng)絡(luò)通信質(zhì)量和網(wǎng)絡(luò)指標(biāo)。 在這種情況下，監(jiān)控系統(tǒng)的建成使用很有必要。本文針對我國國內(nèi)電信運(yùn)營商移動無線網(wǎng)絡(luò)各類直放站的使用情況，各直放站網(wǎng)絡(luò)監(jiān)控點(diǎn)分布特點(diǎn)（如無電信有線傳輸、范圍較廣、距離遙遠(yuǎn)、數(shù)量眾多、不夠集中等），并根據(jù)現(xiàn)代移動無線通信技術(shù)的應(yīng)用及發(fā)展情況，提出一種利用GSM短消息進(jìn)行數(shù)據(jù)傳輸?shù)臒o線參數(shù)采集方案，來遠(yuǎn)程遙控網(wǎng)管數(shù)據(jù)。GSM移動無線網(wǎng)絡(luò)比較完善，覆蓋面大、運(yùn)行穩(wěn)定，根據(jù)無線通信技術(shù)應(yīng)用發(fā)展趨勢，，文章提出一種新方案，利用GSM無線網(wǎng)絡(luò)短信業(yè)務(wù)進(jìn)行遠(yuǎn)程無線數(shù)據(jù)采集實(shí)現(xiàn)監(jiān)控直放站設(shè)備的目的，即利用短消息數(shù)據(jù)傳輸來進(jìn)行網(wǎng)管數(shù)據(jù)的遙測。成本低是系統(tǒng)最大的優(yōu)勢，具體體現(xiàn)在設(shè)備投資建設(shè)成本低，設(shè)備運(yùn)行成本低，設(shè)備維護(hù)費(fèi)用低等方面。研究無線直放站網(wǎng)絡(luò)采用SMS進(jìn)行數(shù)據(jù)自動采集實(shí)現(xiàn)網(wǎng)絡(luò)監(jiān)控，本課題具有一定的創(chuàng)新性和實(shí)用價(jià)值。 課題主要是研究基于GSM無線網(wǎng)絡(luò)短消息傳輸模型，實(shí)現(xiàn)無線網(wǎng)絡(luò)直放站設(shè)備運(yùn)行數(shù)據(jù)遠(yuǎn)距離傳輸。建成直放站監(jiān)控系統(tǒng)，為更好維護(hù)直放站設(shè)備提供可靠的依據(jù)。這個(gè)系統(tǒng)具有成本低的優(yōu)勢，綜合造價(jià)小，在一次性投資建設(shè)成本低，設(shè)備成本低，系統(tǒng)運(yùn)行成本低，系統(tǒng)維護(hù)費(fèi)用低等幾個(gè)方面都有所體現(xiàn)。本課題分析研究了移動無線GSM網(wǎng)絡(luò)短消息的傳輸原理，解決直放站在使用過程中實(shí)時(shí)數(shù)據(jù)遠(yuǎn)距離傳送的問題，實(shí)現(xiàn)自動采集及傳送直放站監(jiān)控?cái)?shù)據(jù)，更好的維護(hù)及優(yōu)化直放站網(wǎng)絡(luò)。 本文的工作主要集中在以下幾個(gè)方面： 1．監(jiān)測中心主機(jī)與短信模塊的通信。監(jiān)測中心通過短信模塊實(shí)現(xiàn)與下位機(jī)的通信，從而實(shí)現(xiàn)監(jiān)測數(shù)據(jù)的接收與監(jiān)測命令的發(fā)送。 2．單片機(jī)控制短信模塊收發(fā)短消息。將現(xiàn)場采集的數(shù)據(jù)傳送到上位機(jī)的短信模塊，并接收上位機(jī)發(fā)送的監(jiān)測命令。 3．現(xiàn)場數(shù)據(jù)采集系統(tǒng)。用單片機(jī)系統(tǒng)實(shí)現(xiàn)電壓、發(fā)射功率的數(shù)據(jù)采集，并按一定格式存入數(shù)據(jù)存儲區(qū)，供傳輸數(shù)據(jù)時(shí)取用。 4．監(jiān)測軟件的設(shè)計(jì)。通過簡單直觀的人機(jī)界面顯示來反映系統(tǒng)的工作流程，便于工作人員進(jìn)行各種操作。
[Abstract]:Repeater is an important part of wireless system in mobile network. It can cover places where the signal of mobile base station is poor. The extent and intensity of mobile network coverage depends to a large extent on the use of the repeater monitoring system, which is used to collect data on the operation of various monitoring points. It is of great significance and value to study the application of repeater monitoring system. Nowadays, most manufacturers of repeater equipment in China are small manufacturers, and the technical level of manufacturing equipment is insufficient. After failure of repeater equipment, it is generally possible to know the actual use of the equipment through user reflection, and the equipment does not have network monitoring. A large part of the equipment used in the repeater station is used indoors, and in remote mountainous areas, some signals cover deep areas. It is very slow to deal with the problem. If there is no monitoring, it is difficult to solve the problem of repeater equipment quickly, which will seriously affect the network communication quality and network indicators. In this case, the establishment and use of the monitoring system is very necessary. This paper aims at the use of various kinds of repeater stations in China's domestic telecom operators' mobile wireless networks, and the distribution characteristics of the network monitoring points of each repeater station (such as no telecommunication wired transmission, etc.). According to the application and development of modern mobile wireless communication technology, a wireless parameter acquisition scheme using GSM short message for data transmission is proposed. To remote control network management data. GSM mobile wireless network is relatively perfect, large coverage, stable operation. According to the development trend of wireless communication technology, this paper puts forward a new scheme. The purpose of remote wireless data acquisition based on GSM wireless network short message service is to realize the purpose of monitoring repeater equipment, that is, to use short message data transmission to carry out telemetry of network management data. Low cost is the biggest advantage of the system. It is embodied in the aspects of low cost of equipment investment and construction, low cost of equipment operation and low cost of equipment maintenance, etc. This paper studies that wireless repeater network uses SMS to collect data automatically to realize network monitoring. This subject has certain innovation and practical value. This paper mainly studies the short message transmission model based on GSM wireless network, realizes the long-distance transmission of the equipment running data of the wireless network repeater station, and builds up the repeater monitoring system. This system has the advantages of low cost, low comprehensive cost, low construction cost in one-time investment, low equipment cost, low operating cost of the system. In this paper, the transmission principle of short message in mobile wireless GSM network is analyzed and studied to solve the problem of remote transmission of real-time data in the process of using repeater. Automatic acquisition and transmission of repeater monitoring data, better maintenance and optimization of repeater network. The work of this paper is mainly focused on the following aspects:. 1. The communication between the host computer and the short message module of the monitoring center, which realizes the communication between the monitoring center and the lower computer through the short message module, so as to realize the receiving of the monitoring data and the sending of the monitoring command. 2. The single chip microcomputer controls the SMS module to send and receive short messages. The data collected in the field is transmitted to the SMS module of the host computer, and the monitoring commands sent by the host computer are received. 3. Field data acquisition system. Data acquisition of voltage and transmitting power is realized by single-chip microcomputer system, and stored in data storage area according to certain format, which can be used when transmitting data. 4. The design of monitoring software. It can reflect the work flow of the system by simple and visual display of man-machine interface, which is convenient for the staff to carry out various operations.
