Abstract

The invention provides a serial port master-slave communication control system and method to be used for solving the problems that, in the prior art, a master-slave communication structure is complex and the number of serial ports is limited. A main control card counts according to the clock period when sends a control signal to an auxiliary card and stops counting when the number achieves a preset coded value, generates into a coded pulse signal according to the clock period of the coded value and the main control card and sends a debugging serial port signal and a control signal after coding in a time-sharing multiplex mode through a serial port, the auxiliary card receives the debugging serial port signal and the control signal after coding sent by the main control card and decodes the control signal after receives the control signal to gate or close the serial port of the corresponding channel.

Description

technical field [0001] The invention relates to the communication field, in particular to a serial port master-slave communication control system and method. Background technique [0002] Serial port technology is a very mature low-speed communication interface. In today's high-density high-speed systems, it is still widely used in many intelligent and manageable chips and cannot be replaced. In large-scale systems such as communication equipment, one master card and multiple slave cards are often designed to support multiple slave cards. These slave cards are of various types and can be added or removed flexibly. The connection between the slave card and the main control card is usually connected by a shared backplane or cable. In addition to the service signal interface, the interface signals between the slave card and the main control card usually reserve power supply, management, and debugging interfaces; The intelligence is getting higher and higher, there will be mult...
