The invention relates to the technical field of integrated circuit low-power-consumption control, and discloses a low-power-consumption control method and system for a fuze chip. The low-power-consumption control method of the fuze chip is applied to chip control equipment, and specifically comprises the following steps: S101, detecting the working state of a functional module electrically connected with the fuze chip within a preset stage time, and judging whether the current state of the functional module is an idle state or not; and S102, if the function module is in the working state, monitoring the operation parameters of the function module, and determining whether the operation parameters of the function module have threshold value changes within the preset stage time. Through precise detection of the idle state of the functional module and delay protection and state verification before the clock is closed, it is ensured that necessary data storage and state synchronization are completed before the functional module enters the low-power-consumption state, system faults caused by sudden interruption of clock signals are avoided, and meanwhile the low-power-consumption requirement and operation reliability are considered.

This invention discloses a multi-stage time synchronization method for a structural health monitoring array, comprising: preprocessing a floor acceleration signal with unknown time delay; calculating the initial delay of the floor acceleration signal based on cross-correlation; calculating the residual time delay of the floor acceleration signal based on wave propagation constraints; calculating the residual time delay of the floor acceleration signal based on cross-spectral phase; reconstructing the synchronized floor acceleration signal using the initial delay, residual time delay, and residual time delay; calculating the displacement response through integration; and outputting the inter-story displacement. This invention divides the synchronization process into three sequential stages: the first stage rapidly reduces the large time delay to the order of several vibration periods; the second stage further refines the process, controlling the residual time delay within one period; and the third stage utilizes phase information to achieve high-precision synchronization while limiting the frequency range to avoid the influence of high-frequency noise.

The invention discloses a frequency agility frequency synthesizer system capable of keeping phase consistency, relates to the technical field of frequency synthesis, and forcibly constrains an originally asynchronous and random frequency updating request to a determined time node generated by a frequency dividing circuit. And the frequency of the synchronous trigger signal becomes a common divisor of all preset output frequencies, namely the output frequency and the trigger frequency are in an integral multiple relationship. No matter when the system sends out a frequency hopping instruction, the actual frequency switching action is always standardized at the determined zero-phase time points, so that the phase randomness introduced due to uncertain instruction arrival time is eliminated, the phases of output signals are strictly consistent in any two processes of hopping from the same frequency to the same frequency, and the frequency hopping efficiency is improved. And phase maintenance and repeatability are realized.
