【摘要】：为了保证通讯基站工作的稳定性,基站监控系统不可或缺。基站监控系统一般采用2M专线网络进行组网从而实现监控中心对基站的集中监控,这种监控方式需要为基站专门铺设通信线缆,成本较高。也有部分方案采用GPRS或短信实现监控组网,但这两种方案在网络速率和实时性方面受限较大。现阶段,VPN技术成熟稳定,并且3G/4G通信发展迅速,网络覆盖率不断增加、稳定性也不断增强。基于这些情况,本文尝试采用VPN和3G/4G组网方式构建一个基站监控系统。本文开发的基站监控系统由VPN服务器、监控中心和基站现场监控单元三部分组成。整个基站监控系统的开发可以分为三点描述:1)通过向运营商申请一个固定公网IP地址,在Linux系统上采用L2TP协议构建VPN服务,为监控中心和现场监控单元的通信提供数据链路;2)在Windows系统下采用Node.js技术实现监控中心Web后台接口,从而为现场监控单元进行数据同步和上传提供通信接口,并采用MFC编程框架实现监控中心桌面客户端;3)在Linux系统中使用RS485通信协议实现现场监控单元的现场数据采集,定时向监控中心传输数据,并结合SQLite数据库的触发器功能实现数据存储、告警关联,实现监控系统的告警处理;采用Node.js技术实现现场监控单元Web后台接口,从而为监控中心主动监控现场监控单元提供通信接口。通过以上工作,本文设计并实现了一个基于VPN组网的基站远程监控系统,该系统实现了基站基本信息设置、基站数据的实时监控、基站历史数据和告警数据查询功能。
[Abstract]:In order to ensure the stability of communication base station, the base station monitoring system is indispensable.The base station monitoring system generally uses 2m special line network to form the network to realize the monitoring center to the base station centralized monitoring, this kind of monitoring way needs to lay the communication cable specially for the base station, the cost is high.Some schemes also use GPRS or SMS to implement monitoring and networking, but these two schemes are limited in network speed and real time.At present, 3G/4G technology is mature and stable, and 3G/4G communication is developing rapidly, network coverage is increasing, and stability is increasing.Based on these conditions, this paper attempts to use VPN and 3G/4G to build a base station monitoring system.The base station monitoring system developed in this paper consists of three parts: VPN server, monitoring center and base station monitoring unit.The development of the whole base station monitoring system can be divided into three parts: 1) by applying for a fixed public network IP address to the operator, the VPN service is constructed by using the L2TP protocol on the Linux system.To provide data link for the communication between the monitoring center and the field monitoring unit. The Web background interface of the monitoring center is realized by using Node.js technology under the Windows system, which provides the communication interface for the data synchronization and uploading of the field monitoring unit.The MFC programming framework is used to realize the desktop client of the monitoring center. In the Linux system, the RS485 communication protocol is used to realize the field data acquisition of the field monitoring unit, and the data is transmitted to the monitoring center at regular time.Combined with trigger function of SQLite database to realize data storage, alarm association, alarm processing of monitoring system, Node.js technology to realize Web background interface of field monitoring unit,Thus, the communication interface is provided for the active monitoring and control unit of the monitoring center.Through the above work, this paper designs and implements a base station remote monitoring system based on VPN network. The system realizes the base station basic information setting, the base station data real-time monitoring, the base station history data and the alarm data inquiry function.
