KJ725-J mine intrinsic safety information transmission

The role of the transmission interface is to convert the data format. The data of the underground substation is uploaded to the ground through the communication cable laid in the roadway, and the transmission interface converts its 485 signal to RS232 signal to the ground central station; The signal is given to the ground central station, so that the central station can collect underground data; at the same time, the transmission interface has the isolation function of intrinsic safety and non-intrinsic safety.
