【Abstract】 A software design of data collection and transmission layer about remote measurement and control system in oil well based on RTU is introduced. The software design to achieve data collection, data transmission and outside relay control in various sensors is discussed. Modbus/RTU and Modbus/TCP communication are also analyzed. The results show that with the help of configuration software, the system can work in more than one mode, which makes it available in different occasions.更多还原
