Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] The core idea of the present invention is: using the serial data bus, the main control unit on the main control board assigns the bus node number to the main control board and each service board, and then connects to the local serial port externally, and uses the serial number according to the bus node number to The serial data bus realizes the serial data transmission to the main control board and all business boards. At the same time, the local serial ports on the main control board and each service board are reserved, so that data interaction between any local serial port and the serial data bus can be realized.
[0027] As shown in Figure 1, the serial port management device of the communication system equipment of the present invention is distributed on the main control board and each service single board, and the main c...
