METHOD AND DEVICE FOR DETECTING FAULT OF SIGNAL PROCESSING EQUIPMENT AND OPTICAL INTERFACE BOARD ONLINE

WIPO Patent Application WO/2010/145438

A1

A method and device for detecting the fault of a signal processing equipment and an optical interface board online are disclosed. The signal processing equipment includes n function modules F1, F2… Fn, and n fault detecting points T1, T2… Tn for determining whether there is a fault in said n function modules, wherein n is a natural number. When the detecting result of said detecting point Ti indicates there is a fault in the function module Fi, the corresponding detecting points of the other function modules directly associated with the function module Fi are detected continuously, and the reason of the fault is determined according to all the fault function modules. The present invention divides the equipment or the board into different modules in accordance with functions, a fault detecting point being set in each module. Therefore, the fault source point of the equipment or the board can be detected and located quickly without artificial participation, and the self-detection can be done automatically when the board is idle to detect problems promptly, so as to improve the testability and the on-site maintainability of products.
