Event-driven measurement system comprising a master sensor and associated measurement method. The invention relates to an event-driven measurement system (1) and its associated method, in which a network (10) of sensors performs measurement cycles comprising: measuring a parameter from time t0 until time t when the measurement reaches a threshold or limit time, then sending a read request (22); at least one master sensor (110) is selected from among these sensors; a logic circuit (12) receives two requests (22) from the master sensor (110), determines (31), for each request (22), a measurement time tmes, determines (32) a difference Δtmes between these measurement times tmes, and when the difference Δtmes is greater in absolute value than a value Δtmes-th, triggers (33) a measurement event (4).

The application discloses a world time continuous solution method, comprising: obtaining and preprocessing the solution result files of each session in a predetermined time range; applying uniform constraints to each session after preprocessing, and performing parameter blocking and local parameter elimination; constructing a sliding time window in a target time range, parameterizing the world time by using a segmented linear function in the window, and establishing a session and time node mapping relationship; constructing a sliding time window on a global time axis, collecting sessions in the window, superimposing a session weight equation, adding a time node smoothing constraint, and jointly solving the world time residual increment; superimposing a priori on the joint solution result, recovering a tidal term, and generating a world time continuous sequence. The application solves the problems of the existing world time product, such as limited time resolution based on daily parameter level combination, insufficient utilization of session level observation geometry and equation information, sensitivity to modeling differences of different session types, and difficulty in adapting to the existing reference framework.
