具体实施方式
下面将结合本公开的实施例中的附图，对本公开的实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开的实施例提供一种货架系统，如图1和图2所示，包括：货架10、信号发射单元20、信号接收单元30和处理单元40。其中，货架10包括承载体101，承载体101可以承载物品，物品一般为非透明的，例如可以将待出售的商品摆放在承载体101上。信号发射单元20位于承载体的一侧，与承载体101之间形成一定距离，信号发射单元20用于发射信号。信号发射单元20所发射的信号可以为光学信号、电学信号、声学信号等。信号接收单元30用于接收信号发射单元20发射的信号。信号接收单元30设置于货架10的承载体101上。当接收到信号发射单元20发射的信号时，信号接收单元30会发生电学变化，并将该电学变化 输出给处理单元40。处理单元40与信号接收单元30电连接(图中未标识出连接关系)，用于根据信号接收单元30输出的信号，获取承载体101上物品的存放状态。物品的存放状态例如可以是承载体101上某一区域内是否存在物品，又例如可以是物品的存放数量等。
需要说明的是，第一，货架10可以为单层货架10，也可以为多层货架10。当为多层货架10时，相应的承载体101也具有多个，且层叠设置。
第二，信号接收单元30设置于承载体101上并不限于直接设置于承载体101上，也可间接设置于承载体101上，例如将包括信号接收单元30的信号接收板设置于承载体101。
信号接收单元30可以设置于承载体101的上方，也可设置于承载体101的下方，只要在没有物品遮挡的情况下能接收到信号发射单元20发射的信号即可。
第三，相对于信号接收单元30在被物品遮挡而未接收到信号发射单元20发射的信号，当信号接收单元30由于没有被物品遮挡而接收到信号发射单元20发射的信号时，可以输出不同的量值。
第四，信号发射单元20固定于货架10上，其设置位置可以使其发射的信号射向承载体101，以使没有被物品遮挡住的信号接收单元30能接收到信号发射单元20发射的信号。例如对于承载体101上有物品存放的位置，由于物品覆盖了信号接收单元30，使被物品覆盖了的信号接收单元30无法接收到信号发射单元20发射的信号，而对于承载体101上没有存放物品的位置，信号接收单元30可以接收到信号发射单元20发射的信号。两种情况所产生的电学变化不同，处理单元40可根据该电学变化获取承载体101上是否有物品存放。
第五，处理单元40固定于货架10上，可根据其与信号接收单元30的连接关系，合理设置其位置。处理单元40例如可以为处理器，处理器可以是中央处理单元(CPU)或者具有数据处理能力和/或程序执行能力的其它形式的处理单元，例如现场可编程门阵列(FPGA)或张量处理单元(TPU)等。
第六，本领域技术人员应该明白，所述货架系统还包括电源线，用于向该货架系统进行供电。
本公开的实施例提供一种货架系统，通过设置信号发射单元20、信号接收单元30和处理单元40，并使信号接收单元30设置于货架10的用于承载物品的承载体101上，可使得处理单元40能根据信号接收单元30输出的信号获知货架10 上物品的存放状态，从而可节省人力物力进行物品存放状态的巡视。
在本公开的一个或多个实施例中，信号接收单元30为多个，且阵列排布于承载体101上。
由于信号接收单元30均与处理单元40连接，因而，将信号接收单元30阵列排布可易于布线而与处理单元40实现电连接，而且信号接收单元30阵列排布容易对每个信号接收单元30的位置信息进行判断。阵列排布例如可以呈矩形阵列排布、三角形阵列排布、圆形阵列排布等。在一个实施例中采用矩形阵列排布，此种设置可以更方便对于被物品覆盖和未覆盖的信号接收单元30的面积进行计算，进而获取物品存放的数量，提高处理速度和实时性。
在本公开的一个或多个实施例中，如图1和图2所示，信号发射单元20包括信号发射板201，信号发射板201与承载体101相对设置。
可以理解的是，信号发射板201与承载体101之间的间距能足够容纳物品。
此外，每层的承载体101都对应一个信号发射板201。当货架10为多层时，本层的信号发射板201可靠近上一层的承载体101设置。
通过信号发射板201与承载体101相对设置，使信号发射板201发射的信号能垂直的射向承载体101。这样，信号发射板201与承载体101所形成的存放物品的空间中，被物品遮挡的信号接收单元30无法接收到信号发射板201发射的信号，而未被物品遮挡的信号接收单元30则可以接收到信号发射板201发射的信号，从而根据承载体101上所有信号接收单元30输出的信号，可获取货架10的承载体101上物品的存放状态。其中，信号发射板201可进行整面信号发射，以使承载体101上任意位置在没有被物品遮挡时，都可以接收到信号发射板201发射的信号。
在本公开的一个或多个实施例中，信号接收单元30为光敏元件，信号发射单元20为光信号发射单元。
其中，光敏元件可以为光敏电阻、光敏二极管等光敏器件。
光敏元件种类较多，可选择性较广，因而可选择较能较好成本较低的光敏元件。
在本公开的一个或多个实施例中，如图3所示，所述信号发射板201为导光板。在此情况下，所述信号发射单元20还包括设置于导光板一侧的光源202。
具体的，光源202例如可以为条形光源。光源202发出的光经过导光板后成 为面光源，导光板的靠近承载体101的一侧为出光侧。面光源向下照射射向承载体101，面光源的出光更加均匀。
如图4a、图4b和图4c所示，在承载体101的存在物品的位置处，光线照射在物品上，从而使得被物品覆盖的光敏元件无法接收到光线，而在承载体101的不存在物品的位置处，光线照射在光敏元件上。以光敏元件为光敏电阻为例，当光敏元件未接收到光照时，其阻值较大，当接收到光照时，其阻值变小。
可以理解的是，对于导光板、光源202的固定方式不做限定，只要使二者相对位置不发生移动即可。此外，对于放置在货架10上的物品可以为不透明包装的物品。
在信号接收单元30为光敏元件的情况下，通过导光板配合光源202的方式，既使得结构简单又使得成本较低。
在本公开的一个或多个实施例中，如图5和图6所示，所述货架系统还包括告警模块60。告警模块60与处理单元40电连接，用于当物品的存放数量小于预定阈值时，产生告警信息。其中，物品的存放状态包括物品的存放数量。
具体的，当货架10为多层货架10时，可基于每层的物品的存放数量独立与预定阈值进行比较而产生告警信息，也可基于货架10上多层的物品的存放数量与预定阈值进行比较而产生告警信息。其中，预定阈值可以根据实际需要进行设定，每层货架10所设定的阈值可以不同，也可根据实际售货情况及物品需求量对设定阈值进行实时调整。
此外，告警模块60固定于货架10上，具体设置位置可根据实际情况进行设定。告警模块60产生告警信息的形式不做限制，例如可以通过喇叭进行缺货状态播报等。
本公开的实施例中，通过告警模块60产生告警信息，可提醒工作人员货架10上的物品处于即将缺货状态，从而进行提前预警。
在本公开的一个或多个实施例中，如图7所示，所述货架系统还包括通信模块70，用于将告警模块60产生的所述告警信息发送至移动终端。
可以理解的是，当处理单元40具有控制功能时，通信模块70与处理单元40连接，以在处理单元40的控制下，将所述告警信息发送至移动终端。否则，所述货架系统可以包括控制单元，与告警模块60、通信模块70等连接，以控制通信模块70将告警模块60产生的告警信息发送至移动终端。
由于移动终端包括手机、IPAD等比较普及，因此，通过将告警信息发送至移动终端，可使工作人员即使离开工作区域，也可及时获得告警提示，从而可及时对物品进行补充。
在本公开的一个或多个实施例中，通信模块70还用于将标识货架10的标识信息以及所述货架上物品的存放数量发送至移动终端。
具体的，当货架10为多层货架10时，可对货架10的每层赋予一个唯一的标识信息，而将每层的标识信息以及该层中物品(即该层的承载体101上的物品)的存放数量发送至移动终端。或者，也可给一个货架10赋予一个唯一的标识信息，而将该货架10的标识信息以及该货架10每层(即每个承载体101)上的物品的存放数量发送至移动终端。或者，也可给一个货架10赋予一个唯一的标识信息，而将该货架10的标识信息以及该货架10所有层(即所有承载体101)上的物品的存放数量发送至移动终端。
本公开的实施例中，通过将标识货架10的标识信息以及所述货架10上物品的存放数量发送至移动终端，可使工作人员随时了解各货架10，甚至货架10的各层的物品的存放数量。
可选的，如图2、图3、图6和图7所示，承载体101和信号发射板201之间设置有支架102，承载体101和信号发射板201由支架102固定。这样，使得本公开的货架系统结构简单且方便实现。
可以理解的是，支架102属于货架10的一部分。
可选的，所述承载体101包括支撑体1011和线路板1012。信号接收单元30设置于线路板1012上，所述线路板1012位于支撑体1011远离信号发射板201一侧。
其中，信号接收单元30可设置于线路板1012的靠近支撑体1011一侧。根据信号发射板201所发射信号的不同，支撑体1011的材料能使信号发射板201所发射的信号透过，从而可射向线路板1012。当信号发射板202所发射的信号为光信号时，支撑体1011例如可以为玻璃、塑料等透明支撑体1011。在一个或多个实施例中，该支撑体1011为板状，并且因此承载体101也为板状的承载体。另外，在一个或多个实施例中，支撑体1011上可以为网状，并且因此承载体101也为网状的承载体，其在信号接收单元30的对应位置处具有开口，能使信号发射板201所发射的信号透过，从而可射向线路板1012上的信号接收单元30。
一方面，同时设置支撑体1011和线路板1012，位于支撑体1011上的物品不会与信号接收单元30接触，可以起到保护信号接收单元30的作用，以提高信号接收单元30的使用寿命。另一方面，将信号接收单元30设置于线路板1012上时，也可将处理单元40设置于线路板1012上。这样，在制作线路板1012时，通过相应的信号线，可很容易的实现信号接收单元30与处理单元40的电连接。
本公开的实施例还提供一种上述的货架系统的监控物品的方法，如图8所示，包括：
S10、信号接收单元30在接收到信号发射单元20发射的信号时输出第一量值到处理单元40，未接受到信号发射单元20发射的信号时输出第二量值到处理单元40。
此处，当信号接收单元30未接收到信号发射单元20发射的信号时，根据器件自身特性，信号接收单元30输出能被测量的第一量值。当信号接收单元30在接收到信号发射单元20发射的信号时，信号接收单元30会发生电学变化，从而输出能体现该电学变化的第二量值。
其中，第一量值和第二量值可以为电阻、电流、电压等电学特性值。
可以理解，第一量值和第二量值为同类型的电学特性值。
S11、处理单元40根据信号接收单元30输出的信号，获取货架10的承载体101上物品的存放状态。
本公开的实施例提供一种货架系统的监控物品的方法。当信号接收单元30未被物品遮挡时，由于接收到信号发射单元20发射的信号而输出第一量值，当信号接收单元30被物品遮挡时，由于无法接收到信号发射单元20发射的信号而输出第二量值，使得处理单元40可以根据信号接收单元30输出的量值，获取货架10上物品的存放状态，例如可以获取承载体101上某一区域内是否存在物品，或可更精确的计算出物品的存放数量等，从而可节省人力物力进行物品存放数量的巡视。
在本公开的一个或多个实施例中，所述物品的存放状态包括物品的存放数量。所述方法还包括：当物品的存放数量小于预定阈值时，由告警模块60产生告警信息。
具体的，当货架10为多层货架10时，可基于每层的物品的存放数量独立与预定阈值进行比较而产生告警信息，也可基于货架10上所有层的物品的存放数 量与预定阈值进行比较而产生告警信息。
通过告警模块60产生告警信息，可提醒工作人员货架10上的物品处于即将缺货状态，从而进行提前预警。
在本公开的一个或多个实施例中，处理单元40根据所述信号接收单元30输出的信号，获取货架10的承载体101上物品的存放状态，包括：当处理单元40判断有理货动作发生后，根据信号接收单元30输出的信号，计算货架10的承载体101上物品的存放数量。
其中，判断有理货动作发生，包括：获取靠近货架10入口的承载体101上预设区域范围(参考图4a和图4b的虚线框)内的所有信号接收单元30输出的第一量值或第二量值，并进行求和计算得到总量值；将总量值与初始总量值进行比较，若总量值与初始总量值具有差值(即差值不为0)，并在预设时间后，总量值与初始总量值相等，则判断有理货动作发生。
在本公开的一个或多个实施例中，所述方法还包括：获取靠近货架10入口的承载体101上预设区域范围内的所有信号接收单元30输出的第一量值，得到所述初始总量值。
以信号接收单元30为光敏电阻为例，在没有理货装置(例如人手、机械臂等)进入货架10时，位于货架10入口的承载体101上预设区域范围内的光敏电阻全部处于光照中(参考图4a-4c所示)而均输出第一量值。该第一量值为电阻值，或能体现其电阻值的电压或电流值。此时预设区域范围内的光敏电阻的总阻值最小，作为初始总量值。当有理货装置进入货架10时，光线会照射在理货装置上，由于理货装置一般为非透明，从而使被理货装置遮挡的入口处的部分光敏电阻不能接收到光照(参考图9a-图9c所示)输出第二量值。该第二量值为电阻值，或能体现其电阻值变化的电压或电流值。因而预设区域范围内的光敏电阻的总阻值相对初始总量值变大。当理货装置撤出货架10时，预设区域范围内的光敏电阻的总阻值又会变为最小，等于初始总量值。这样，通过检测位于货架10入口的承载体101上处预设区域范围内的光敏电阻总阻值的变化情况，就可以检测到是否有理货动作发生。
其中，本公开将从货架10上拿出或放回物品的动作称为理货。
需要说明的是，由于对于货架10的每层而言，其都构成一个存放物品的空间。该空间具有多个侧面，将其中一个侧面作为拿出、放回物品的必经口，称为 货架10入口。
在设定靠近货架10入口的承载体101上预设区域范围(参考图4a和图4b的虚线框)时，使得该预设区域范围内不放置物品。其中，根据信号接收单元30的设置密度，靠近货架10入口预设区域范围内的所有信号接收单元30例如可以是靠近货架10入口的一排信号接收单元30，也可以是两排甚至多排。
其中，对于预设区域范围可根据具体情况进行合理设置，能用于判断是否有理货装置进入即可。
或者，在本公开的一个或多个实施例中，处理单元40根据信号接收单元30输出的信号获取货架10的承载体101上物品的存放状态，包括：当处理单元40判断有理货动作发生后，根据信号接收单元30输出的信号，计算货架10的承载体101上物品的存放数量。
其中，判断是否有理货动作发生，包括：根据承载体101上输出第二量值的信号接收单元30的变化轨迹，判断是否有理货动作发生。
仍以信号接收单元30为光敏电阻为例，当有理货装置进入货架10时，信号发射单元20的光线会照射在理货装置上，使得被理货装置遮挡的光敏电阻由于不能接收到光照而输出第二量值。而且，随着理货装置的移动，被遮挡的光敏电阻也在发生变化。因而，根据被遮住的光敏电阻的变化轨迹可判断是否有理货动作发生。
通过在确认有理货动作发生后再计算货架10上物品的存放数量，可减少运算量，因而可降低对处理单元40性能的需求。
基于上述，计算货架10的承载体101上物品的存放数量，包括：获取货架10的承载体101上输出第一量值的信号接收单元30的个数n t；通过公式
Figure PCTCN2018108916-appb-000002
计算货架10的承载体101上物品的存放数量m t。
其中，M为承载体101上达到物品存放数量最大值时的总物品数量，n 0为承载体101上达到物品存放数量最大值时输出第一量值的信号接收单元30的个数，N为承载体101上所有信号接收单元30的总个数。
仍以信号接收单元30为光敏电阻为例，每个光敏电阻所占面积为S R，没有光照到光敏电阻时其阻值为R，当承载体101上达到物品存放数量最大值时阻值小于R的光敏电阻数目(即被光照到输出第一量值的光敏电阻数目)为n 0，那么 可以计算出承载体101上达到物品存放数量最大值时，被物品遮住的光敏电阻数目为N-n 0，被遮住的光敏电阻的面积为S R(N-n 0)。
假设被遮住的光敏电阻的面积与承载体101上物品所占面积相等，当承载体101上达到物品存放数量最大值时的总物品数量为M，时，可计算得到每个物品所占的面积S 0，
Figure PCTCN2018108916-appb-000003
在其他任意时刻，可以检测到光敏电阻阻值小于R的数目(即被光照到输出第一量值的光敏电阻数目)为n t，那么此时承载体101上物品的数量m t，

将
Figure PCTCN2018108916-appb-000005
带入到
Figure PCTCN2018108916-appb-000006
中，便可得到上述公式
Figure PCTCN2018108916-appb-000007
基于此，只需要知道承载体101上达到物品存放数量最大值时的总物品数量M、承载体101上达到物品存放数量最大值时输出第一量值的信号接收单元30的个数n 0、承载体101上所有信号接收单元30的总个数N、以及任意时刻承载体101上输出第一量值的信号接收单元30的个数n t，就可以计算得到此时刻承载体101上物品的数目m t。
需要说明的是，上述以信号接收单元30为光敏电阻为例进行推导上述公式，但从推导过程可以看出，最终结果仅与M、n 0、N、n t有关，因此，对于信号接收单元30为其他器件也适用于本公开。
此外，由上述推导可以看出，在计算S 0是以承载体101上物品面积相等为前提的，因此，在实际应用中，可在承载体101上放置同种类的物品。
另外，在每个物品都对应于一个信号接收单元30的情况下，也可以直接得出M＝(n-n 0)以及m t＝(n-n t)，即，承载体101上达到物品存放数量最大值时，物品的总物品数量M等于被物品遮住的光敏电阻数目(N-n 0)，以及在任意时刻，承载体101上物品的数目m t等于承载体101上所有信号接收单元30的总个数N减去此时刻承载体101上输出第一量值的信号接收单元30的个数n t。
在本公开的一个或多个实施例中，所述方法还包括：在计算得到承载体101上物品的存放数量后，将本次计算的数量与本次理货动作发生之前的数量进行比较，得到本次理货动作发生后，所述承载体101上的物品存放数量变化情况。
可将本次理货动作发生之前承载体101上物品的存放数量记为m q，本次计算 的承载体101上物品的存放数量为m t与m q存在如下三种关系：
m t>m q，表示有物品被放入；
m t<m q，表示有物品被取出；
m t＝m q，表示物品的存放数量没变或者没有商品被放入或取出。
本公开的实施例通过将本次计算的数量与本次理货动作发生之前的数量进行比较，可获知本次理货动作发生前后，承载体101上的物品存放数量变化情况。
在本公开的一个或多个实施例中，在计算得到承载体101上物品的存放数量后，将本次计算的数量与本次理货动作发生之前的数量进行比较，得到本次理货动作发生后，所述承载体101上的物品存放数量变化情况，包括：在计算得到承载体101上物品的存放数量后，将本次计算的数量与初始数量进行比较，以得到本次理货动作发生后，承载体101上的物品存放数量变化情况；其中，所述初始数量为本次理货动作发生之前承载体101上物品的存放数量；之后将本次的数量值赋予所述初始数量。
即，将每次计算的承载体101上物品的存放数量与初始数量进行比较，而本次比较所用的初始数量均由上一次计算的承载体101上物品的存放数量赋予。
在本公开的一个或多个实施例中，所述方法还包括：由通信模块70将告警模块60产生的告警信息发送至移动终端。
通过将告警信息发送至移动终端，可使工作人员即使离开工作区域，也可及时获得告警提示，从而可及时对物品进行补充。
在本公开的一个或多个实施例中，所述方法还包括：将标识货架10的标识信息以及所述货架10上物品的存放数量发送至移动终端。
具体的，当货架10为多层货架10时，可对货架10的每层赋予一个唯一的标识信息，而将每层的标识信息以及该层中物品(即该层的承载体101上的物品)的存放数量发送至移动终端。或者，也可给一个货架10赋予一个唯一的标识信息，而将该货架10的标识信息以及该货架10每层(即每个承载体101)上的物品的存放数量发送至移动终端。或者，也可给一个货架10赋予一个唯一的标识信息，而将该货架10的标识信息以及该货架10所有层(即所有承载体101)上的物品的存放数量发送至移动终端。
下面提供一种具体的货架系统的监控物品的方法，其中，货架系统的信号接收单元30为光敏电阻，如图10所示，该方法包括：
S20、进行初始化。

S201、获取承载体101上各光敏电阻输出的电阻。
S202、计算得到靠近货架10入口的承载体101上一排光敏电阻的初始总阻值。
S203、计算承载体101上物品的初始数量(记为m)。
其中，S202和S203，都是以S201中获取的信息为前提的。
承载体101上物品的初始数量的计算可通过
Figure PCTCN2018108916-appb-000008
进行计算，M、n 0、N为已知量，而根据S201获取的信息可统计得到光敏电阻阻值小于R的数目，该数目即为n t。
需要说明的是，初始化时，要求货架10没有理货动作。
S21、获取承载体101上各光敏电阻输出的电阻。
S22、判断靠近货架10入口的承载体101上一排光敏电阻的总阻值是否变大，如果变大，则进行S23，否则进行S21。

S24、在预设时间内，判断靠近货架10入口的承载体101上一排光敏电阻的总阻值是否变为初始总阻值，若是，进行S25，否则进行S23。
其中，若在预设时间内总阻值未变为初始总阻值，则可通过告警模块60发出告警，以使工作人员确认是否有物品放置于靠近货架10入口的承载体101上一排光敏电阻上。
S25、获取承载体101上各光敏电阻输出的电阻，计算承载体101上物品的数量m t。

S26、判断承载体101上物品的数量是否小于预定阈值，若是，进行缺货预警。
