For example, the aforementioned reaction time represents the shortest interval time of the discrete detectors for two consecutive detections, and the range is about 1 to 50 seconds, and the preset value can be about 8 seconds. In practice, the discrete detector can be an infrared sensor or other sensing device.
第3圖是依照本發明一實施例之一種開放式冷藏櫃的控制方法300的流程圖,第4圖是依照本發明一實施例之一種開放式冷藏櫃的控制方法300的時序圖。開放式冷藏櫃包含櫃體與捲簾裝置,櫃體具有開放式展示面,捲簾裝置具有透明捲簾。如第3圖所示,控制方法300包含步驟310、320(應瞭解到,在本實施例中所提及的步驟,除特別敘明其順序者外,均可依實際需要調整其前後順序,甚至可同時或部分同時執行)。至於實施該些步驟的硬體裝置,由於上一實施例已具體揭露,因此不再重複贅述之。 3 is a flow chart of a control method 300 for an open refrigerator according to an embodiment of the present invention, and FIG. 4 is a timing chart of a control method 300 for an open refrigerator according to an embodiment of the invention. The open refrigerated cabinet comprises a cabinet and a roller blind device, the cabinet has an open display surface, and the roller blind device has a transparent roller blind. As shown in FIG. 3, the control method 300 includes steps 310 and 320. It should be understood that the steps mentioned in the embodiment can be adjusted according to actual needs, except for the order in which the sequence is specifically described. It can even be executed simultaneously or partially). As for the hardware device for carrying out these steps, since the previous embodiment has been specifically disclosed, the description thereof will not be repeated.
於步驟310,感應是否有至少一人體位於櫃體的開放式展示面前。步驟320,當人體位於櫃體的開放式展示面前時(如第4圖之有人狀態410),驅動馬達去控制捲簾裝置將透明捲簾維持在捲回的狀態,使得開放式展示面呈現敞開的狀態,以便於消費者拿取櫃內所陳列的食品。 In step 310, it is sensed whether at least one human body is located in front of the open display of the cabinet. Step 320, when the human body is located in front of the open display of the cabinet (as in the human state 410 of FIG. 4), the drive motor controls the roller blind device to maintain the transparent roller blind in the rewinding state, so that the open display surface is open. The state, so that consumers can take the food displayed in the cabinet.
於一實施例中,步驟320包含:基於一顧客平均選購時間Toc(繪示於第4圖)以決定透明捲簾在捲回的狀態下的維持時間。舉例來說,前述的顧客平均選購時間Toc代表單一使用者平均在櫃體前選購的時間,其範圍約在 10~400秒之間,預設值可約為40秒。 In one embodiment, step 320 includes determining a maintenance time of the transparent roller blind in the retracted state based on a customer average purchase time Toc (shown in FIG. 4). For example, the aforementioned average customer purchase time Toc represents the average time that a single user purchases in front of the cabinet, and the range is about The preset value can be about 40 seconds between 10 and 400 seconds.
於一實施例中,步驟320更包含:基於人體位於櫃體的開放式展示面前的停駐時間,來延長透明捲簾在捲回的狀態下的維持時間,藉此,在銷售尖峰期時,於步驟320能自動延長捲簾開的時間,以避免捲簾關閉而影響顧客消費。實作上,當顧客的停駐時間愈長,維持時間就會被延長得更久(如第4圖之延時狀態420)。 In an embodiment, step 320 further includes: extending the holding time of the transparent roller blind in the rewinding state based on the dwell time of the human body in front of the open display of the cabinet, thereby, during the peak period of sales, In step 320, the opening time of the roller blind can be automatically extended to prevent the roller blind from closing and affecting customer consumption. In practice, the longer the customer's dwell time, the longer the hold time will be (as in the delay state 420 of Figure 4).
於一實施例中,步驟320更包含:設定透明捲簾在捲回的狀態下的維持時間不超過一最大持續時間Tmc(繪示於第4圖),亦即將此最大持續時間Tmc作為維持時間的上限值,以避免維持時間被無限制的延長。舉例來說,前述的最大持續時間Tmc代表透明捲簾最大可持續開啟的時間,其範圍約在30~1000秒之間,預設值可約為300秒。 In an embodiment, the step 320 further includes: setting the maintenance time of the transparent roller blind in the rewinding state to not exceed a maximum duration Tmc (shown in FIG. 4), that is, the maximum duration Tmc is taken as the maintenance time. The upper limit is used to avoid an unrestricted extension of the maintenance time. For example, the aforementioned maximum duration Tmc represents the maximum sustainable opening time of the transparent roller blind, and the range is about 30 to 1000 seconds, and the preset value may be about 300 seconds.
於一實施例中,步驟320更包含:當顧客離開,無人體位於櫃體的開放式展示面前時(如第4圖之無人狀態440),控制器150開始進行維持時間倒數。當維持時間倒數結束後(如第4圖之結束狀態430),若未感應到人體,控制捲簾裝置將透明捲簾捲出,使得開放式展示面被透明捲簾遮蔽。藉此,當遇到離峰期時,於步驟320能自動縮短捲簾開的時間,以達到節能效果。 In one embodiment, step 320 further includes: when the customer leaves without the human body in front of the open display of the cabinet (such as the unmanned state 440 of FIG. 4), the controller 150 begins to perform the countdown of the maintenance time. When the end of the maintenance time is over (as in the end state 430 of Figure 4), if the human body is not sensed, the control roller blind device rolls the transparent roller blind so that the open display surface is obscured by the transparent roller blind. Thereby, when the peak period is encountered, the time of opening the curtain can be automatically shortened in step 320 to achieve the energy saving effect.
於一實施例中,步驟310包含:藉由一離散型偵測器每間隔一反應時間去偵測否有人體位於櫃體的開放式展示面。舉例來說,前述的反應時間代表離散型偵測器連續兩次偵測的最短間距時間,其範圍約在1~50秒之間,預設 值可約為8秒。實作上,離散型偵測器可為紅外線感應器或其他感測裝置。 In one embodiment, step 310 includes detecting, by a discrete detector, a reaction time interval between the human body and the open display surface of the cabinet. For example, the aforementioned reaction time represents the shortest interval time of the discrete detectors for two consecutive detections, and the range is about 1 to 50 seconds. The value can be approximately 8 seconds. In practice, the discrete detector can be an infrared sensor or other sensing device.
