【摘要】：直放站是移动网络无线系统的一个重要组成部分，它能覆盖到移动基站信号较差的地方，扩大并加强移动网络覆盖区域和强度。移动网络覆盖的强弱很大程度取决于直放站监控系统的使用，使用它对各监测点运行情况的数据采集。因此，对研究直放站监控系统的运用具有很大的意义和价值。而现在我国大多直放站设备生产厂商是小厂家，生产制造设备的技术水平不足，直放站设备出现故障后一般通过用户反映才能知道设备实际的使用情况，设备没有网络监控，而直放站设备使用很大一部分都是使用在室内、偏远山区一些信号深层覆盖区域，处理问题很慢，如没有监控，很难快速解决直放站设备问题，势必会严重影响网络通信质量和网络指标。在这种情况下，监控系统的建成使用很有必要。本文针对我国国内电信运营商移动无线网络各类直放站的使用情况，各直放站网络监控点分布特点（如无电信有线传输、范围较广、距离遥远、数量众多、不够集中等），并根据现代移动无线通信技术的应用及发展情况，提出一种利用GSM短消息进行数据传输的无线参数采集方案，来远程遥控网管数据。GSM移动无线网络比较完善，覆盖面大、运行稳定，根据无线通信技术应用发展趋势，，文章提出一种新方案，利用GSM无线网络短信业务进行远程无线数据采集实现监控直放站设备的目的，即利用短消息数据传输来进行网管数据的遥测。成本低是系统最大的优势，具体体现在设备投资建设成本低，设备运行成本低，设备维护费用低等方面。研究无线直放站网络采用SMS进行数据自动采集实现网络监控，本课题具有一定的创新性和实用价值。课题主要是研究基于GSM无线网络短消息传输模型，实现无线网络直放站设备运行数据远距离传输。建成直放站监控系统，为更好维护直放站设备提供可靠的依据。这个系统具有成本低的优势，综合造价小，在一次性投资建设成本低，设备成本低，系统运行成本低，系统维护费用低等几个方面都有所体现。本课题分析研究了移动无线GSM网络短消息的传输原理，解决直放站在使用过程中实时数据远距离传送的问题，实现自动采集及传送直放站监控数据，更好的维护及优化直放站网络。本文的工作主要集中在以下几个方面： 1．监测中心主机与短信模块的通信。监测中心通过短信模块实现与下位机的通信，从而实现监测数据的接收与监测命令的发送。 2．单片机控制短信模块收发短消息。将现场采集的数据传送到上位机的短信模块，并接收上位机发送的监测命令。 3．现场数据采集系统。用单片机系统实现电压、发射功率的数据采集，并按一定格式存入数据存储区，供传输数据时取用。 4．监测软件的设计。通过简单直观的人机界面显示来反映系统的工作流程，便于工作人员进行各种操作。
[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.
