Weak link tracking system

The utility model relates to a weak link tracking system which is characterized by comprising an on-line data sharing unit which is connected with a data collection and monitor control unit, wherein the on-line data sharing unit is also in communication with a comprehensive data unit and a plurality of client ends through a network State estimation results are saved by an on-line data sharing platform of the weak link tracking system, and cooked data are directly acquired from the on-line data sharing platform by all kinds of modules. Compared with a prior mode, the weak link tracking system is advantageous in that repeated construction and repeated maintenance of a state estimation system can be prevented, all kinds of modules can be free of repeated state estimation computation, and good real-time performance is realized.
