【Abstract】 The framework of telemetry and telecontrol water supply based on digital microwave network is described in this paper. It researched that the parameter of antenna and the special terrain and landform have effect on communication error rate. This paper brings forward data redundancy and cyclic code to control error rate, carrier wave detects and linear increment back arithmetic to ensure the network speed and fault diagnosis methods of hardware. Thus, the reliability and safety of this system are ensured.更多还原
