Description

撿料方法及系統Material picking method and system

本發明是有關於一種撿料方法，特別是指一種用於在大型倉儲進行撿料作業的撿料方法。 The present invention relates to a material picking method, and in particular to a material picking method for performing material picking operations in large warehouses.

隨著網購風行，為了提升競爭力，越來越多業者標榜快速到貨，而在撿料階段提高撿料的速度，是達成快速出貨的方式之一。目前撿料方式是，倉庫的每一倉儲貨架上的每一種物品對應一電子標籤，每一倉儲貨架配置有一燈塔以指引撿料員，撿料員根據倉儲系統發送的撿料單(紙本或者顯示在電子裝置上)上的物品順序找到物品對應的電子標籤以進行撿料。然而，當倉庫的場域寬廣，撿料員在缺乏自身位置資訊以及缺乏自身位置與要被撿取的物品的相對位置關係的資訊下，只憑自身經驗按部就班地進行撿料，並無法提升撿料的效率。因此，如何縮短撿料時間以提升撿料效率便成為一個值得研究的課題。 With the popularity of online shopping, in order to improve competitiveness, more and more businesses are promoting fast delivery. Improving the speed of picking during the picking stage is one of the ways to achieve fast delivery. The current picking method is that each item on each storage shelf in the warehouse corresponds to an electronic tag, and each storage shelf is equipped with a lighthouse to guide the picker. The picker finds the electronic tag corresponding to the item according to the order of the items on the picking list (paper or displayed on an electronic device) sent by the warehouse system to pick the items. However, when the warehouse is wide, the pickers lack information about their own position and the relative position of the items to be picked. They can only pick items step by step based on their own experience, which cannot improve the efficiency of picking. Therefore, how to shorten the picking time to improve the picking efficiency has become a topic worth studying.

因此，本發明的目的，即在提供一種能縮短撿料時間以 提升撿料效率的撿料方法，其能克服上述現有技術的至少一缺點。 Therefore, the purpose of the present invention is to provide a material picking method that can shorten the material picking time to improve the material picking efficiency, which can overcome at least one shortcoming of the above-mentioned prior art.

於是，本發明撿料方法，應用於一倉庫以協助一撿料員在該倉庫進行一撿料作業，該倉庫存放多種物品。該撿料方法包含以下步驟：(I)供該撿料員隨身使用的一行動裝置收到一撿料請求後，該行動裝置令其中的一定位模組接收設置在該倉庫的N(N

3)個無線收發器各別傳送的一定位訊號，且該定位模組根據該等定位訊號的訊號強度運算出該行動裝置在該倉庫中的一位置資訊；其中，該撿料請求包含與多個待撿物品分別對應的多個待撿物品位置資訊；及(II)該行動裝置令其中的一路徑規劃模組根據該位置資訊及該撿料請求包含的該等待撿物品位置資訊，利用一廣度優先演算法產生一最短撿料路徑，且該行動裝置在顯示的該倉庫的一電子地圖中呈現該最短撿料路徑，該最短撿料路徑包含該行動裝置的該位置資訊、該等待撿物品分別對應的該等待撿物品位置資訊以及由該行動裝置到各該待撿物品的一撿料順序。 Therefore, the material picking method of the present invention is applied to a warehouse to assist a material picker in performing a material picking operation in the warehouse, where a variety of items are stored. The material picking method comprises the following steps: (I) after a mobile device used by the material picker receives a material picking request, the mobile device causes a positioning module therein to receive N (N
Figure 111139471-A0305-02-0003-1
3) a positioning signal transmitted by each of the wireless transceivers, and the positioning module calculates a position information of the mobile device in the warehouse according to the signal strength of the positioning signals; wherein the picking request includes a plurality of position information of the items to be picked corresponding to the plurality of items to be picked; and (II) the mobile device instructs a path planning module therein to calculate a position information of the mobile device in the warehouse according to the position information and the picking request. A shortest picking path is generated by using a breadth-first algorithm based on the location information of the waiting items, and the mobile device displays the shortest picking path on an electronic map of the warehouse. The shortest picking path includes the location information of the mobile device, the location information of the waiting items corresponding to the waiting items, and a picking sequence from the mobile device to each of the waiting items.

在一些實施態樣中，其中，該撿料請求還包括一撿料清單，該撿料清單包含該等待撿物品分別對應的多個物料編號及該等待撿物品分別對應的多個撿料數量。 In some implementations, the pick-up request further includes a pick-up list, which includes multiple material numbers corresponding to the items to be picked and multiple pick-up quantities corresponding to the items to be picked.

在一些實施態樣中，其中，該撿料請求是由一倉儲管理伺服器提供。 In some implementations, the picking request is provided by a warehouse management server.

在一些實施態樣中，其中，在步驟(II)中，該撿料順序 是以該行動裝置的該位置資訊與該等待撿物品分別對應的該等待撿物品位置資訊之間的距離由近而遠依序排列。 In some implementations, in step (II), the order of picking up items is arranged in order from near to far based on the distance between the location information of the mobile device and the location information of the items waiting to be picked up corresponding to the items waiting to be picked up.

本發明的另一目的在於提供一種撿料系統，其能克服上述現有技術的至少一缺點。 Another object of the present invention is to provide a material picking system that can overcome at least one disadvantage of the above-mentioned prior art.

在步驟S201中，該倉儲管理伺服器1根據該撿料指令與該倉庫的該電子地圖產生並傳送一包含與該五個待撿物品分別對應的五個待撿物品位置資訊及一撿料清單的撿料請求至該行動裝置100。該撿料清單包含該五個待撿物品分別對應的五個物料編號及該五個待撿物品分別對應的該五個撿料數量。 In step S201, the warehouse management server 1 generates and transmits a picking request including five location information of the five items to be picked and a picking list to the mobile device 100 according to the picking instruction and the electronic map of the warehouse. The picking list includes five material numbers corresponding to the five items to be picked and five picking quantities corresponding to the five items to be picked.

接著，在該行動裝置100收到該撿料請求後，該行動裝置100開始接收該三個無線收發器2各別傳送的該定位訊號。然後，該行動裝置100將接收的該等定位訊號提供給其中的該定位模組3，該定位模組3收到該等定位訊號後，執行步驟S202，在步驟S202中，該定位模組3根據該等定位訊號的訊號強度運算出該行動裝置100在該倉庫中的一位置資訊。該位置資訊例如是但不限於該行動裝置100所在位置對應在該倉庫的該電子地圖上的座標點。 Next, after the mobile device 100 receives the pick-up request, the mobile device 100 starts to receive the positioning signals transmitted by the three wireless transceivers 2. Then, the mobile device 100 provides the received positioning signals to the positioning module 3 therein. After receiving the positioning signals, the positioning module 3 executes step S202. In step S202, the positioning module 3 calculates the location information of the mobile device 100 in the warehouse according to the signal strength of the positioning signals. The location information is, for example, but not limited to, the coordinate point corresponding to the location of the mobile device 100 on the electronic map of the warehouse.

之後，該行動裝置100令其中的該路徑規劃模組4執行步驟S203，在步驟S203中，該路徑規劃模組4根據該位置資訊及該撿料請求包含的該五個待撿物品位置資訊並利用一廣度優先演算 法(Breadth-First Search，BFS)產生一最短撿料路徑。該最短撿料路徑包含該行動裝置100的該位置資訊、該五個待撿物品分別對應的該五個待撿物品位置資訊以及由該行動裝置100到各該待撿物品的一撿料順序。該撿料順序是以該行動裝置100的該位置資訊與該五個待撿物品分別對應的該五個待撿物品位置資訊之間的距離由近而遠依序排列。舉例來說，例如圖3所示，該撿料順序是該行動裝置100(該撿料員隨身使用)→物品

。 Afterwards, the mobile device 100 instructs the path planning module 4 therein to execute step S203. In step S203, the path planning module 4 generates a shortest picking path according to the location information and the location information of the five items to be picked included in the picking request using a breadth-first search (BFS) algorithm. The shortest picking path includes the location information of the mobile device 100, the location information of the five items to be picked corresponding to the five items to be picked, and a picking sequence from the mobile device 100 to each of the items to be picked. The picking order is arranged in order from near to far based on the distance between the location information of the mobile device 100 and the location information of the five items to be picked. For example, as shown in FIG3 , the picking order is the mobile device 100 (used by the picker) → item

.

緊接著，該行動裝置100令其中的該路徑規劃模組4執行步驟S204，在步驟S204中，該路徑規劃模組4讀取該儲存模組5所預先儲存的該倉庫的該電子地圖。然後，該儲存模組5執行步驟S205，在步驟S205中，該儲存模組5提供該倉庫的該電子地圖給該路徑規劃模組4。接著，該路徑規劃模組4執行步驟S206，在步驟S206中，該路徑規劃模組4將該最短撿料路徑疊合在該電子地圖上，並傳送包含該最短撿料路徑的該倉庫的該電子地圖至該顯示模組6。 Next, the mobile device 100 instructs the path planning module 4 therein to execute step S204, in which the path planning module 4 reads the electronic map of the warehouse pre-stored by the storage module 5. Then, the storage module 5 executes step S205, in which the storage module 5 provides the electronic map of the warehouse to the path planning module 4. Next, the path planning module 4 executes step S206. In step S206, the path planning module 4 superimposes the shortest picking path on the electronic map and transmits the electronic map of the warehouse including the shortest picking path to the display module 6.

最後，該顯示模組6執行步驟S207，在步驟S207中，該顯示模組6顯示該倉庫的該電子地圖，並在該電子地圖中呈現該最短撿料路徑。藉此，該撿料員從該行動裝置100的該顯示模組6看到該電子地圖中呈現該最短撿料路徑的該撿料順序(該行動裝置 100→物品
