CELL FAULT MONITORING SYSTEM AND METHOD

Provided in the present invention are a cell fault monitoring system and method. A sampling module monitors, during dormancy and in real time, the state of a corresponding cell, and sends a fault signal when the cell is faulty; the fault signal wakes up a bridging module and all sampling modules by means of an annular daisy chain, which is formed by connecting the bridging module with several sampling modules; the bridging module wakes up a processing module; and after being woken up, the processing module can analyze and process the fault of the cell. By means of the present invention, fault detection and wake-up of a cell fault monitoring system during dormancy can be completed by means of an annular daisy chain, without the need for complex circuit modules and components, such that the system is simple, the reliability is good, and the cost is low. La présente invention concerne un système et un procédé de surveillance de défaut de cellule. Un module d'échantillonnage surveille, pendant la dormance et en t
