Method and system for supporting transparent transmission of serial interfaces

Abstract

The invention discloses a method for supporting transparent transmission of serial interfaces. The method comprises the following steps: a first universal asynchronous serial interface of a micro-controller receives real-time communication data of monitored equipment in an interruption receiving manner, and stores the real-time communication data in a first cache array; the newly received data in the first cache array is forwarded to a second universal asynchronous serial interface, and forwarded to communication equipment through the second universal asynchronous serial interface; the second universal asynchronous serial interface of the micro-controller receives the data of the communication equipment in an interruption receiving manner, and stores the data in a second cache array; and the newly received data in the second cache array is forwarded to the first universal asynchronous serial interface, and forwarded to the monitored equipment through the first universal asynchronous serial interface. By means of the method disclosed by the invention, transparent transmission of data can be realized; furthermore, interfaces of the monitored equipment cannot be occupied; and the transmission delay is very low.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a method and system for supporting transparent transmission of a serial interface. Background technique [0002] Because of its simplicity and ease of implementation, the serial interface is used for device-to-device communication in many self-developed and designed equipment. As people's requirements for equipment intelligence are getting higher and higher, the function division of control units in equipment is becoming more and more detailed, there are more and more control units, cross-linking is becoming more and more complicated, and system debugging and testing are becoming more and more difficult. The probability of system problems in the early stage of development is getting higher and higher, and it is becoming more and more difficult to locate and analyze problems from the data obtained from the monitoring terminal, especially when the number of tests of the whole syste...

Problems solved by technology

As people's requirements for equipment intelligence are getting higher and higher, the function division of control units in equipment is becoming more and more detailed, there are more and more control units, cross-linking is becoming more and more complicated, and system debugging and testing are becoming more and more difficult. The probability of system problems in the early stage of development is getting higher and higher, and it is becoming more and more difficult to locate and analyze problems from the data obtained from the monitoring terminal, especially when the number of tests of the whole system is limited, it is even more difficult to analyze and solve the occasional problems that appear in the tests. extremely difficult

At present, in the debugging and testing phase, the equipment that may have problems is generally monitored by an external serial interface storage disk, but this method must occupy a serial interface on the equipment, and the monitored data is the suspected serial interface forwarded by the processor. The data sent and received by the interface cannot implement online and non-interference data monitoring for the communicating equipment

Checking domestic and foreign patents and literature, there is no introduction and description about the method of supporting transparent transmission of serial interface
