HANDS-FREE ELECTRONIC LOCK SYSTEM

OTANI AKIO

To provide an electronic system capable of stably performing unlocking/locking operation in a hands-free manner.SOLUTION: An electronic lock system has an electronic key 20 including: means for sampling reception electric field strength of a beacon transmitted by an electronic lock 10, stably digitizing unstable reception electric field strength, estimating a distance to the electronic lock 10, and transmitting an unlocking signal to the electronic lock 10; means for stopping processing for transmitting the unlocking signal from detection of the reception electric field strength for a predetermined time duration after transmission of the unlocking signal; and means for stopping estimation of the distance to the electronic lock from the reception electric field strength while the electronic key 20 is connected to a charger 30 by connecting the electronic key 20 to the charger 30 within the stopping period.SELECTED DRAWING: Figure 1

【課題】本発明は安定的にハンズフリーでの解錠、施錠を行うことのできる電子システムを提供する。【解決手段】電子キー２０は電子錠１０が発信するビーコンの受信電界強度をサンプリングして、不安定な受信電界強度を安定数値化し、電子錠１０までの距離を推定し、電子錠１０へ解錠信号を送信する手段、解除信号送信後の予め定められた時間、受信電界強度の検出から解錠信号を送信する処理を停止する手段、その停止期間内に電子キー２０を充電器３０へ接続することで、電子キー２０は充電器３０と接続中、受信電界強度から電子錠までの距離推定を停止する手段を備えることを特徴とする電子錠システム。【選択図】図１
