The invention discloses a touch screen gesture recognition system of a power operation monitoring center. The touch screen gesture recognition system comprises pressure sensing modules arranged on a touch screen in a matrix manner, a trajectory extraction module, a storage module and a trajectory comparison module, wherein each pressure sensing module is provided with a counting unit and a timing unit which are used for counting and timing pressure acting on the pressure sensing module; the trajectory extraction module is used for recording the positions of the pressure sensing modules receiving the pressure so as to form the trajectories of operations on the touch screen; the storage module is used for storing the standard operation trajectory of various operation gestures on the touch screen; the trajectory comparison module is used for comparing the operation trajectories extracted by the trajectory extraction module and the standard operation trajectories stored in the storage module and performing corresponding operations according to matched standard operation trajectories.
