Anti-error unlocking method and anti-error lock cylinder

摘要

The present application provides an anti-error unlocking method, constant to: obtain parameters of the lock cylinder; obtain unlocking data; the unlocking data comprising: when the unlocking conditions are satisfied, the upward displacement ΔH of the pin and the distance h between the tip of the key and the ejection mechanism; get a trigger node to judge if the current key is a good key; get actual data once the tip of the wrench reaches the trigger node; the actual data including the upward ΔH 'displacement of each pin; comparing ΔH 'of the real data with ΔH of the unlocking data; if these are not identical, an eject operation will be performed. The error-proof lock cylinder provided in the present application is to obtain a trigger node to judge whether the current key is a good key and to judge the correctness of the current key at the position of the trigger node through a comparison, When the judgment conditions are not satisfied, the key ejection operation will be performed immediately, which can make judgment quickly during key insertion and thus avoid problems caused by continuous insertion , and allows the user to immediately know a bad key and correct.
