Embodiment 1

[0030] The system composition of this embodiment is an implementation method for debugging serial ports in a dual-master control system. The system consists of a main control board A and a main control board A', an interface board, and a backboard.

[0031] 1) The main control board A is the configuration main control, and the main control board A' is the debugging main control, such as figure 2 Shown:

[0032] When the serial port CON1202 of the main control board A' needs to be connected to the serial port of the interface board A, access the EPLD-2204 of the main control board A' through the serial port CON1201 of the main control board A through the inter-board bus 207, and configure the EPLD-2204 register to select the interface board A serial port, and open the controllable driver A'206 of the main control board A', and the group of serial port signals is connected to the interface board processor module B208 through the backplane. At this time, the main control board ...

Embodiment 2

[0036] The system composition of this embodiment is an implementation method for debugging serial ports in a dual master control system. The system consists of a main control board A, a main control board A', an interface board A, and an interface board B backplane.

[0037] 1) The main control board A is the configuration main control, and the main control board A' is the debugging main control, such as Figure 4 Shown:

[0038] When the serial port CON1202 of the main control board A' needs to be connected to the serial port of the interface board A, access the EPLD-2204 of the main control board A' through the serial port CON1201 of the main control board A through the inter-board bus 207, and configure the EPLD-2204 register to select the interface board A serial port, and open the controllable driver A'206 of the main control board A', and the group of serial port signals is connected to the interface board processor module B208 through the backplane.

Abstract

The invention discloses a method for implementing a debugging serial port in a dual main control system. The system includes a main control board A, a main control board A', at least one interface board, and a backboard; the main control board A and the main control board A' back each other; at least one group of serial buses are arranged on the main control board A and the main control board A';the main control boards and the interface board are interconnected through a socket. In the invention, a configuration main control can access a debugging main control at any time through a board bus,and then it is ensured that the debugging main control serial port can freely switch between various interface boards and a board processor; no difference exists between the actual operability and anold design, and the number of the debugging serial ports of the dual main control system is reduced by half.

Description

technical field [0001] The invention relates to the field of circuit design, in particular to a method for transmitting and processing serial port signals between a main control board and an interface board on a communication device. Background technique [0002] On a distributed system communication device, there are multiple card slots on one device. The slots are divided into main control slots and interface board slots. Different slots are connected to each other through the backplane. The whole system is controlled by the main control board to manage. Usually the main control board panel will provide a debugging serial port to debug the main control board itself and the interface board. A typical system architecture is attached figure 1 As shown, the system is mainly composed of three parts: the main control board, the backplane, and the interface board. There are usually one or two main control boards and many interface boards. When there are two main control boards...
