Development of Data Acquisition Module for Dam Safety Monitoring Based on MSC1210

Safety of dam is very important for the social stability and smooth development. A kind of multi-functional data acquisition module based on SCM MSC1210 is introduced, which is a core component of a distributed dam safety monitoring automation system. The system is composed of monitoring sensor, data acquisition module, and monitoring host computer. The module of data acquisition is in charge of output data acquisition, processing, and storing from monitoring sensors, and communication with monitoring host computer. Besides, it can check signals of voltage, current, frequency, and impedance, and communicate with host computer using RS-485 and GPRS wireless and mutual backup modes. The working principle, hardware composition, and anti-jamming measures of the data acquisition module are studied with stress. The system adopts the new progress in measuring and communication technologies, and improves the precision, reliability, expansibility, and simplification of the application.
