Abstract:Aiming at the performance degradation of network control system caused by packet-loss, taking the urban sewage disposal system monitoring network with wide geographical distribution as study object, based on giving a mathematical model of pump station and subsequently establishing a switch model of monitoring network packet-loss according to the asynchronous dynamical system, this paper puts forward a network packet-loss intelligent compensation strategy. Then the compensation strategy is simulated by the Truetime platform, and some experiments on the operational control of local pumping stations are done. The results show that the compensation strategy is effective to enhance the control performance of the sewage disposal monitoring network system.
