Abstract:Tailings pond safety online monitoring system demands real-time communication and continuous acquisition of monitoring data. However, the natural and industrial environment of the system is complex, so how to improve communication reliability of the system has become a big problem. This paper proposes a series of security technologies of multi redundant network communication, distributed intelligent power supply, self diagnosis of network fault, data stored and retransmission, system lightning and surge protection, system data fault tolerance, communication of QoS management and so on. The industrial field test shows that the specific technologies proposed in this paper could effectively improve the reliability of communication.
