The Software Design And Implementation Of VPN-based Remote Monitoring System For Base Station

In order to ensure the stability of communication base station work,base station monitoring system is indispensable.Base station monitoring system generally use 2M green network method to achieve the monitoring center of the centralized monitoring of the base station,this monitoring method for the laying of communication cables dedicated to the base station,the higher the cost.There are some programs using GPRS or SMS to achieve monitoring network,but these two programs in the network speed and real-time limited.At this stage,VPN technology is mature and stable,and 3G / 4G communication is developing rapidly,the network coverage is increasing and the stability is increasing.Based on these circumstances,this paper attempts to use VPN and 3G / 4G networking to build a base station monitoring system.The base station monitoring system developed in this paper is composed of three parts: VPN server,supervision center and field supervision unit.The development of the entire base station monitoring system can be divided into three parts:1)Through the fixed public IP address,in the Linux system using L2 TP protocol to build VPN services for the monitoring center and the monitoring unit between the communication unit to provide data link;2)In the Windows system using Node.js technology to achieve the monitoring center Web background interface for field monitoring unit for data synchronization and upload,and based on the MFC programming framework to achieve the monitoring center desktop client;3)In the Linux system using the RS485 communication protocol to achieve on-site monitoring unit of the field data acquisition,timing to the monitoring center to transmit data,combined with SQLite database trigger function to achieve data storage,alarm association,to achieve monitoring system alarm;use Node.js technology to achieve onsite monitoring unit Web background interface for the monitoring center to provide communication interface.Through the above work,this paper designs and realizes the base station remote monitoring system based on VPN network.The system realizes base station basic information editing,real-time monitoring of base station data,base station historical data and alarm data query.
