QDD debugging and testing system

Abstract

The invention discloses a QDD debugging and testing system which comprises a host, a debugging board and a module to be tested. The host is used for outputting protocol instructions; the debugging board and the host establish communication through a local area network; debugging and testing system software is installed in the debugging board; the module to be tested is connected with the debugging board through a flat cable; the debugging board selects a corresponding test function from the debugging and testing system software according to the protocol instructions so as to test the module to be tested; and after the test is completed, the debugging board feeds back a test result to the host. On the basis of being suitable for the QDD module, the QDD debugging and testing system uses the protocol instructions as the communication format of the host and the debugging board, so that the communication quality is ensured, the communication success and failure can be determined through the replied content, the debugging and testing quality of the module to be tested is ensured, and the debugging time of the module to be tested is saved.

Description

technical field [0001] The invention belongs to the technical field of optical module testing, and in particular relates to a QDD commissioning system. Background technique [0002] At present, most of the module debugging and testing methods are mainly to issue commands through the serial port / parallel port through the PC, and the commands are transmitted to the communication interface circuit, then transmitted to the control unit, and finally transmitted to the optical module. By issuing different commands, the purpose of debugging and testing the module is achieved. [0003] In the above-mentioned existing module debugging and testing methods, the serial port / parallel port communication rate is low, and the serial port / parallel port transmission command may occasionally fail to transmit, and the communication quality cannot be guaranteed. Serial port / parallel port communication requires USB communication line for transmission, which is difficult for remote control. And ...

AI Technical Summary

Problems solved by technology

[0003] In the above-mentioned existing module debugging and testing methods, based on the low communication rate of the serial port / parallel port, and using the serial port / parallel port to transmit commands, occasionally transmission failures may occur, and the communication quality cannot be guaranteed.

Serial port / parallel port communication requires USB communication line for transmission, which is difficult for remote control

And there is no special commissioning system for QDD modules, no commissioning system with integrated DSP parameter debugging function
