本申请提出一种智能货柜，参照图1至图5，智能货柜包括柜体10、柜门11以及设置在所述柜门11上的锁孔，所述智能货柜还包括：
锁体20，设置在所述柜体10上，所述锁体20包括锁舌21；第一检测模块31，设置在所述柜体10上，设置为检测所述柜门11的开关状态；第二检测模块32，设置在所述锁体20内部，设置为检测所述锁舌21的伸出状态；第三检测模块33，设置在所述柜门11上，设置为检测所述锁舌21是否伸入锁孔中；控制模块，分别与所述第一检测模块31、第二检测模块32、第三检测模块33以及锁体20电连接。
在本实施例中，锁体20为电插锁，在接收到控制信号后会控制锁舌21伸出，具体的，锁体20设置在柜体10上并位于柜门11的上方，锁体20远离柜体10与柜门11的铰接轴设置。在柜门11上设置有对应的锁片，锁片上设置有锁孔。在柜门11关闭后，锁体20的锁舌21与下方的锁孔相对。柜门11在打开和关闭时会发送第一检测信号至第一检测模块31，控制模块接收到上述第一检测信号，可判断柜门11是处于打开状态还是关闭状态。同样，锁舌21的伸缩过程同样会引起第二检测模块32发送第二检测信号，控制模块接收到上述第二检测信号后可判断锁舌21是否伸出。锁舌21伸入锁孔和离开锁孔都会发送第二检测信号，控制模块接收到上述第散检测信号后可判断锁舌21是否锁入锁孔中。
在本实施例中，柜体10分为上中下三段，上段设置为安装电源模块、PLC、通信模块等电控组件。中段一侧开口设置，内部形成有容纳货物的容腔，在容腔中设置有货架，在容腔内还可设置有对应的自动取货机构。在容腔的顶部和/或侧壁还设置有灯管，设置为提供照明。在柜体10的下端容置有设置为制冷的压缩机。在柜体10的上段还设置有冷凝管，冷凝管与压缩机连通。冷凝管机壳对电控组件降温，还可通过风扇将冷空气抽入中段的容腔中，以控制容腔内部的温度，使智能货柜可存储牛奶、饮料等需要低温储存的货物。
在本实施例中，柜门11则设置在柜体中段的开口处，且柜门11的右侧与开口的右侧铰接，在柜门表面靠近左侧边缘处设置有把手。锁体20设置在柜体10的上段，并靠近柜门11的上端设置。锁体20远离柜体10与柜门11的铰接轴设置，并位于把手的正上方。由此可与铰接轴一起作用，实现对柜门11的左右两侧的锁定。
本专利在现有电插锁基础上，在锁舌21上内嵌一颗磁铁，保持电插锁内部电气方案不变，把此款电插锁安装在柜机上，锁片安装在柜门11对应位置，同时在柜门11型材内部锁舌21落下的对应位置安装干簧管或霍尔开关，此此路信号同样是给到上位机系统。当门关闭，锁舌21落下状态，此路信号可以感应到关信号。由此，当三路信号都为关时，此时智能货柜处于锁止状态，当用户扫码购物时，云端下发开锁指令，此时锁内部第二检测信号为开，之后第三检测信号也为开，当用户拉开门后，第一检测信号也变成开，用户正常进行购物。当用户关门时，三路信号依次变为关，分别为第一检测信号感应为关时，电插锁锁舌21落下，外部第二检测信号感应为关、内部第二检测信号为关。检测信号时软件上需对此三路信号做先后区分。如果信号先后顺序发生异常，则可间接反应智能货柜存在骗关行为，针对异常行为可能存在以下几种，具体处理方式如下表：
通过对三组信号进行严密的逻辑控制后，不仅可以有效检测智能货柜锁是否故障，同时可以实现智能货柜防骗关的功能。
一般违规的骗关手段，会先用一个磁铁靠近第一检测模块31，来模拟柜门关闭的状态，此时第一检测模块31同样会发出第一检测信号至控制模块，控制模块判定柜门11关闭发送关锁指令至锁体20，锁体20控制锁舌21伸出。在没有第三检测模块33的情况下，第二检测模块32检测到了锁舌21伸出后即判断满足结算条件。但事实上柜门11却还处于打开状态。本申请通过设置第三检测模块33设置为验证锁舌21是否进入锁孔中。如果是则满足结算条件，避免了骗关的情况发生。
在一实施例中，参照图1至图5，所述第一检测模块31包括干簧管或霍尔开关，所述柜门11上设置有与所述第一检测模块31对应的第一磁性件。在本实施例中，第一磁性件包括设置在柜门11上的第一磁铁，上述干簧管或霍尔开关设置在柜体10上，在柜门11关闭时，第一次磁铁靠近干簧管或霍尔开关，实现对柜门11开关状态的检测。此外第一检测模块31还可选择设置在柜体10中的行程开关，当柜门11关闭时触动行程开关输出第一检测信号，无需设置第一磁性件也可实现对柜门11开关状态的监控。值得注意的是，上述控制模块可选PLC控制板，上述的干簧管、霍尔开关或行程开关与控制模块电连接，实现控制信号和第一检测信号的传输。
在一实施例中，参照图1至图5，第二检测模块32包括设置在所述锁体20内部的微动开关或红外对管，所述微动开关和红外对管的探测端朝向所述锁舌21设置。在本实施例中上述的微动开关和红外对管设置在锁体的内部，同样与控制模块电连接，实现控制信号和第二检测信号的传输。锁体20包括壳体、滑动设置在壳体内部的锁舌21、驱动锁舌21伸缩的线圈以及与线圈电连接的PCB板，PCB板与控制模块电连接。微动开关设置在PCB板上，其探测端位于锁舌21的运动路径上。在锁舌21伸出时会触动微动开关导通发送电信号。在锁舌21收缩时微动开关断开电信号发生改变。红外对管同样设置在PCB上，包括发射管和接收管，上述发射管和接收管分设于发射路径的两侧。在锁舌21收缩时，接收管可接收到发射管发出的红外光，当锁舌21伸出后，由于锁舌21的阻挡，接收管接收不到发射管发出的红外光，由此输出的信号发生改变，通过对上述信号的甄别即可获知锁舌21的伸缩状态。
在一实施例中，参照图1至图5，所述第三检测模块33包括设置在所述柜门11中的干簧管或霍尔开关，所述锁舌21上设置有与所述第三检测模块33对应的第二磁性件22。在本实施例中，干簧管又叫磁簧开关，磁簧开关是由两片磁簧片密封在玻璃管内，通常由铁和镍这两种金属所组成。两片磁簧片呈重迭状况但中间间隔有一小空隙，仅约几个微米。外来适当的磁场将会使两片磁簧片接触，簧片的作用相当与一个磁通导体。在尚未操作时，两片簧片并未接触，在通过永久磁铁或电磁线圈产生的磁场时，外加的磁场使两片簧片端点位置附近产生不同的极性，当磁力超过簧片本身的弹力时，这两片簧片会吸合导通电路；当磁场减弱或消失后，干簧片由于本身的弹性而释放，触面就会分开从而打开电路，由此可实现对锁舌21中的第二磁性件22的检测。
霍尔开关就属于这种有源磁电转换器件，它是在霍尔效应原理的基础上，利用集成封装和组装工艺制作而成，它可方便的把磁输入信号转换成实际应用中的电信号，同时又具备工业场合实际应用易操作和可靠性的要求。霍尔开关的输入端是以磁感应强度B来表征的，B值达到一定的程度（如B1），霍尔开关内部的触发器翻转，霍尔开关的输出电平状态也随之翻转，由此可实现对锁舌21中的第二磁性件22的检测。
在一实施例中，参照图1至图5，所述锁舌21的自由端设置有安装孔，所述第二磁性件22设置在所述安装孔中。在本实施例中，第二磁性件22为设置在安装孔中的磁性小球。上述的干簧管、霍尔开关或行程开关与控制模块电连接，实现控制信号和第一检测信号的传输。在一实施例中，参照图1至图5，所述智能货柜还包括设置在所述柜体10上，并靠近所述柜体10和柜门11的铰轴设置的第四检测模块，所述第四检测模块设置为检测所述柜门11的开关状态。由于干簧管、霍尔开关以及行程开关具备一定的探测范围，可能存在柜门11没完全关闭却触发了第一检测模块31和第三检测模块33的情况。通过在靠近铰轴的区域设置第四检测模块可从两路上检测柜门11的位置，避免了检测误差，同时也增加了骗关的难度。
在一实施例中，参照图1至图5，还可在柜门的下方设置另一个锁体，在柜门上设置与该锁体的锁舌对应的锁孔。该锁体同样位于远离柜门门轴的一侧，具体可相对的设置在上方锁体的正下方，实现对柜门的上下两端双重锁定，避免从下端撬开柜门盗损货物的情况发生。下方的锁体仅需安装于上方锁体中的第二检测模块对应的微动开关即可，控制模块接收到第三检测信号之后即可控制下方锁体锁定。
本申请还提出一种货柜控制方法，参照图1至图7，该货柜控制方法应用于上述的智能货柜，包括以下步骤：
S21：接收第一检测模块31发送的第一检测信号，判断柜门11的开关状态；在本步骤中，当柜门11的状态发生变化后，第一检测模块31会产生第一检测信号，并将第一检测信号发送至控制模块，控制模块分析上述第一检测信号，判断柜门11目前为打开状态或关闭状态。
S22：在确定柜门11关闭后，发送关锁指令至锁体20，控制锁舌21伸出；在本步骤中，在控制模块判定柜门11为关闭状态后，会发送关锁指令至锁体20，锁体20接收到上述关锁指令后驱动锁舌21伸出。
S23：接收第二检测模块32发送的第二检测信号，判断锁舌21的伸缩状态；在本步骤中，锁舌21的伸缩状态改变后，第二检测模块32会产生第二检测信号，并将第二检测信号发送至控制模块，控制模块分析上述第二检测信号，判断锁舌21目前为伸出状态或收缩状态。如果第二检测模块32没有发出第二检测信号，则判断货柜故障，具体可能是锁体20故障，也可能是第二检测模块32故障。
S24：在确定锁舌21伸出后，接收第三检测模块33发送的第三检测信号，判断锁舌21是否伸入锁孔中。在本步骤中，在控制模块判定锁舌21为伸出状态后，如果锁舌21伸入锁孔中，第三检测模块33会产生第三检测信号，并将第三检测信号发送至控制模块，控制模块接收到上述第三检测信号即可判断锁舌21伸入锁孔中。
在满足上述三路信号均为关闭状态，则控制智能货柜进入结算流程。本申请通过对三组信号进行严密的逻辑控制后，不仅可以有效检测智能货柜锁体20是否故障，同时可以实现智能货柜防骗关的功能。
在一实施例中，参照图1至图7，所述接收第一检测模块31发送的第一检测信号，判断柜门11的开关状态的步骤前，还包括：
S11：接收用户的购买申请信息，控制锁体20开锁；在本步骤中，当用户扫码购物时，云端下发开锁指令，此时锁内部第二检测信号为开，之后第三检测信号也为开。
S12：接收第一检测模块31发送的第一检测信号，根据第一检测信号判断柜门11的开关状态，并在柜门11打开后进入取货流程；当用户拉开门后，第一检测信号也变成开，用户正常进行购物。
S13：再次接收第一检测模块31发送的第一检测信号，判断柜门11的开关状态，在柜门11关闭后判定取货流程完毕，并计算取货流程的取货时长；在用户完成取货后，将柜门11关闭，第一检测模块31发送第一检测信号至控制模块，控制模块根据第一检测信号判断柜门关闭。随后计算柜门11一开一关之间的时长，即上述的取货时长。
S14:确定取货时长大于第一预设时长，判断取货流程异常。在本步骤中，控制模块将上述的取货时长与第一预设时长比对，第一预设时长为2~3min。确定取货时长超出第一预设时长则判定取货流程异常，货柜存在盗损风险，随后控制模块将异常情况发送至云端或管理人员的移动设备，上传本次取货流程中货柜外置摄像头录制的取货视频，以供人工判断和处理异常。
在一实施例中，参照图1至图7，所述控制智能货柜进入结算流程的步骤前，还包括：
将接收到关锁指令至接收到第三检测信号时的落锁时长与第二预设时长进行比对；在本步骤中，锁体20接收到关锁指令一般会立即执行关锁动作，从锁体20接收到关锁指令到锁舌21落入锁孔之间的时间间隔为毫秒级，定义以上时间段为落锁时长，第二预设时长为50~500ms，通过将落锁时长和第二预设时长比对可从时间维度上进行判定信号是否延迟。
确定落锁时长大于第二预设时长，判定锁门异常。在本步骤中，控制模块输出判断结果，如果落锁时长小于和等于第二预设时长则说明信号无延迟，锁舌21成功落锁。如果有延迟即落锁时长大于第二预设时长，则说明存在骗锁情况，外部人员可能通过将磁铁放入锁孔中，模拟锁舌伸出的磁场环境。但是很难同时模拟柜门关闭和锁舌伸出时的分别对第一检测模块31和第三检测模块33的两种磁场环境，本实施例增加了一项判定条件，可进一步避免骗锁。
在一实施例中，参照图1至图7，所述发送关锁指令至锁体20，控制所述锁舌21伸出的步骤前，还包括：接收第四检测模块的第四检测信号，根据第四检测信号，判断柜门11的开关状态。在本步骤中，由于干簧管、霍尔开关以及行程开关具备一定的探测范围，可能存在柜门11没完全关闭却触发了第一检测模块31和第三检测模块33的情况。通过在靠近铰轴的区域设置第四检测模块可从两路上检测柜门11的位置，避免了检测误差，同时也增加了骗关的难度。即使外部人员同时模拟柜门关闭和锁舌伸出时的分别对第一检测模块31和第三检测模块33的两种磁场环境，但是还要模拟出针对第四检测模块的磁场环境，而且在时间顺序上满足闭锁条件，其成功几率更低。
在一实施例中，参照图1至图7，所述在柜门11关闭时，发送关锁指令至锁体20，控制所述锁舌21伸出的步骤还包括：
锁体20接收到所述关锁指令，等待第三预设时长后控制锁舌21伸出；在本步骤中，通常锁体20在接收到关锁指令后，锁体20会立刻执行关锁动作，立刻驱动锁舌21伸出。本步骤中通过预设程序，在锁体20接收到关锁指令后等待第三预设时长再执行关锁动作。其中第三预设时长为一随机时长，具体为0.5~2s，相邻两次关锁动作时等待的第三预设时长不相等，每次关锁动作中的第三预设时长的设定通过内置在锁体20内部的算法控制。
将锁体20接收到关锁指令至接收到第三检测信号时的第一关门时长与所述第三预设时长进行比对；由于上述第二预设时长即锁体20的锁门时长为毫秒级，在此可忽略，因此要求第一关门时长应该等于第三预设时长。
在所述第一关门时长等于第三预设时长时进入结算流程。在本步骤中，如果第一关门时长大于或者小于第三预设时长，说明存在骗关情况或者存在设备异常。
在一实施例中，参照图1至图7，所述在柜门11关闭时，发送关锁指令至锁体20，控制所述锁舌21伸出的步骤还包括：在柜门11关闭后，等待第四预设时长发送关锁指令至锁体20，在本步骤中，锁体20在接收到关锁指令后，锁体20会立刻执行关锁动作，驱动锁舌21伸出。本申请中，通过设置第四预设时长作为检验条件。
将接收到第一检测信号至接收到到第三检测信号时的第二关门时长与所述第三预设时长进行比对；在所述第二关门时长与所述第四预设时长匹配时进入结算流程。由于上述第二预设时长即锁体20的锁门时长为毫秒级，在此可忽略，因此要求第一关门时长应该等于第四预设时长。在本步骤中，如果第一关门时长大于或者小于第三预设时长，说明存在骗关情况或者存在设备异常。
上述两个实施例都是从时间维度上，增加结算条件，由于每次关锁动作中的第三预设时长和第四预设时长为随机时长，因此外部人员不可能按照先后顺序和预设的时间间隔模拟出三路信号，从技术上使骗关行为无法成功。
本申请在功能上完全实现了智能货柜防骗关的功能；同时通过软件检测，可实现检测柜机锁相关部件及锁是否产生异常，一旦有异常可及时通过管理后台给到售后进行预警，方便售后对柜机及时排查故障；可准确判断锁舌21实际状态及柜门11是否真实锁止。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
