Remote Data Collection System for Rural Distribution Network Based on GPRS and VPN

A new remote data acquisition system for rural distribution network is proposed in this paper.The previous communication modes have shortcomings such as high construction costs,serious data losses,low capacity of resisting disturbance in the rural area.The remote data acquisition system,whose data transmission platform consists of GPRS and the tunnel transmission technique of VPN,is proposed and it also overcomes all the shortcomings of the previous rural communication modes.Through the experiment,the results declare that the communication mode with GPRS and VPN can span the independent,secure and steady communication tunnels,and realize the steady wireless communications between rural distributed RTU and monitoring center,but,also advance the reliability and security of the data transmission.The whole system can realize the data acquisition and communication system for rural distribution network unattended,low costs and low maintenance costs combined with the edited software program on the host computer.
