2 results about "Near critical" patented technology

The application discloses a kind of anti-misoperation control methods of telescopic support, it includes: real-time acquisition of the current state of support and wind data;When support is in folded state, judge whether wind data satisfies unfolding condition;If it satisfies, then cumulative unfolding timing;If it does not satisfy, then clear zero unfolding timing;When unfolding timing reaches preset unfolding delay, control support to execute unfolding action and update current state to unfolded state;When support is in unfolded state, judge whether wind data satisfies folding condition;If it satisfies, then cumulative folding timing;If it does not satisfy, then clear zero folding timing;When folding timing reaches preset folding delay, control support to execute folding action and update current state to folded state.The application is through the delay judgment mechanism of "cumulative-clearing", ensure that only when wind condition continues to be stable and meet the requirements, trigger support action, effectively filter transient wind fluctuation, avoid the frequent misoperation caused by gust oscillation near critical wind speed.
