Abstract State information acquisition is an indispensable part for MCSEM(marine controllable source electromagnetic) transmitter system which is important for MCSEM exploration. Especially under the conditions of high voltage, high temperature and strong interference, it plays an inestimable role in the reliable and stable operation of the instrument. Based on the principles of simplicity, ease of use, reliability and high safety factor, the state acquisition technology for the new generation of MCSEM transmitter system is designed and implemented by using the technology of CAN bus, serial port, optical fiber and wireless network. Test shows that the technical scheme of state acquisition is simple, stable and reliable.It has meet the harsh requirements of MCSEM transmitter system and has been applied to the exploration of nature gas hydrate in South China Sea.
