| Abstract: | This paper introduces a distributed measuring and monitoring system and its implementation scheme which realizes monitoring of multi point and remote signal on dam of hydrodynamic power station by utilizing PLC. It illustrates the sensor which measures the peg's displacement under water and the method of measuring height of sluice gate by code generator. Then it presents the method to process sample value and to communicate among PLC. This transducer system has good precision and reliability. |
