DSMS-80Ⅱ data acquisition system, a multi-function dam safety monitoring device, is developed for real-time monitoring, capable of receiving various types of outputs from sensors to increase monitoring functions. The system communication uses RS-485 interface to enhance transmission distance, to form a distributed network structure for stations, and to decrease disturbance among stations. As powered directly by a storage battery, charged by AC or float-charging solar energy, the system has a good performance of anti-interference and anti-lightning. The system developed by using a single chip can be connected to the computer for the purpose of real-time monitoring.
