| Abstract: | The data acquisition and transmission unit(DTU) is studied to solve the problem of supervising and early-warning system applied to long-distance water transmission tunnels or mine excavating operations.The know-how of the DTU is an embedded microprocessor with RS485 optical fiber network interface.Under the MODBUS communicating protocol,32 such DTU's can be integrated into a spatially distributed system;with each DTU possessing up to 512 channels of detection signals and sensor outputs.The timely,accurate assembling and prediction of information and events in monitoring and hazard-alarming of long-distance water transmission tunnels or in mine excavating operations are achieved by the online data management software of the central computer.The system offers a new security option for the excavation of tunnels and mines. |
