Research of Workstation Base on CAN Bus

摘要

On the upgrade standard of mine monitor system work station, the RS-485 communication mode cannot meet the challenge. And there are some faults in these modes, and they will infect the capacity of the monitor system To a certain extent, for example: the limited workstation's node number and limited transmitting distance, as well as unavailable communication among nodes, and for the primary importance is that the principal and subordinate communication mode brings about trouble for developing of the watching and controlling of the safety, this paper addressed CAN bus workstation and analyzed the feasibility of turning the RS-485 workstation into CAN bus .The result verified that workstation basing on CAN bus was feasible.
