【Abstract】 The key to the intelligent switch cabinet lies on the communication system design. After analyzing the composition of the intelligent switch cabinet, the highly reliable PROFIBUS-DP field bus is used to design a module composed of SPC3 and 87C196KC as the hardware, with a master-slave structure. The communication circuit is constructed to realize the data exchange function of the system. At the same time, the main program is developed from the software perspective. By the system simulation, the reliability of the data communication of the intelligent switch cabinet is verified.更多还原
