Description of the Invention: [Technical Field] The present invention relates to a warehouse management system and method, and more particularly to a warehouse management system and method based on RFID technology. [Prior Art]
傳統的倉庫管理通常係採用條碼技術來管理貨# 的。當貨物進入倉庫時，作業人員使用條碼設備掃插—下 貨物上的條碼，就可以將該貨物的基本資訊錄入庫存彡 統，完成入貨的操作。出貨的操作與入貨是相同的。然而， 使用條碼技術必須要有人工的參與，因此提高了人力成 本。此外，人工操作必然會帶來效率低及出錯率高等弊端。 為了解決上述弊端，越來越多的企業採用RFID( RadioTraditional warehouse management usually uses bar code technology to manage goods#. When the goods enter the warehouse, the operator uses the barcode device to scan the barcode on the goods, and then the basic information of the goods can be entered into the stock system to complete the operation of the goods. The shipping operation is the same as the incoming goods. However, the use of bar code technology requires manual involvement, thus increasing manpower costs. In addition, manual operations will inevitably lead to low efficiency and high error rates. In order to solve the above drawbacks, more and more enterprises adopt RFID (Radio
Frequency Identification，無線射頻識別）技術來代替條碼 技術。所述RFID技術係一種非接觸式的自動識別技術， 它透過射頻訊號自動識別目標物件並獲取相關資料，識別 工作無須人工的參與，並可在各種惡劣環境下工作。 RFID主要由三部分組成：電子標籤、天線及閱讀器。 所述電子標籤㈣合元件及晶片組成，其安裝於貨物上， 可以用來儲存貨物的基本資訊。所述天線㈣讀取電子標 併發送給閱讀器’或者用於將閱讀器所發出的指 1、、。電子標戴。所述閱讀器用來接收及處理電子標籤 的貝訊或者向電子標籤發送資訊。般都有兩個以 二Ϊ介面，閱讀器在讀到電子標籤的資訊時可以同時 知道該電子钱的資訊是由哪―個天線介 4 201033906 利用RFID技術可以不需要人 條碼，然而，這樣會產± f業去㈣田貨物上的 的電子標籤的資訊時，就是讀取到貨物上 庫還是出庫呢?解決此問題二=道該貨物是要入 法係將讀取到的電子方法通常有兩種，第一種方 較， 參 ❹ 則，若庫存系統中不存在兮^目^〇物為出庫，否 ㈣方法係根據天線判=物為入庫； -在倉庫的_置_個天::斷在’:庫圓的：置我一們 固天線3,當門外的天線3先讀取到貨物 閲讀器2就可以判斷該貨物是要入庫的 ；紙夺 存有=上存“中往_ 愈主更夕條資訊，每次讀取到一條 籤資訊時’都要與該庫存祕中的所有資訊進行對比，: 效率很低’並且會給庫存系統的健㈣來貞擔。採 二種方法來判斷貨物的入庫或者出庫時，rfid閲讀器2 及天線3、4不管是有貨物進出還是沒有貨物進出時都必須 一直處於開啟狀態’這必然造成資源的浪費，如浪費電源 而且會損耗RFID設備，使RFID設備的壽命降低。 【發明内容】 _ 鑒於以上内容，有必要提出一種倉庫管理系統及方 法，其採用紅外線感測器控制RFID閱讀器及天線的開啟 201033906 與關閉，節省了資源，且可以準確地判斷貨物的入庫與出 .庫。 / 一種倉庫管理系統，其利用無線射頻識別技術管理貨 • 物的出庫及入庫。該系統包括電子標籤、天線及閱讀器。 該系統還包括：置於倉庫門内的第一紅外線感測器及置於 倉庫門外的第二紅外線感測器，用於偵測是否有貨物經過 該紅外線感測器的掃描區域，並在有貨物經過時發出訊 號；及控制伺服器，用於接收上述紅外線感測器發出的訊 ® 號，根據該訊號控制閱讀器及天線的開啟與關閉，接收出 庫或者入庫的貨物上所安裝的電子標籤的資訊，根據所接 收的上述紅外線感測器發出的訊號的先後順序判斷該貨物 是要入庫還是出庫，並將上述資訊記錄到一個庫存系統中。 一種倉庫管理方法，其利用無線射頻識別技術管理貨 物的出庫及入庫。所述無線射頻識別包括電子標籤、天線 及閱讀器。該方法包括：準備一個控制伺服器及兩個紅外 Φ 線感測器，其中第一紅外線感測器放置於倉庫門内，及第 二紅外線感測器放置於倉庫門外；開啟上述兩個紅外線感 測器及控制伺服器；第一紅外線感測器及第二紅外線感測 器偵測是否有貨物經過其掃描範圍；當上述兩個紅外線感 測器中的其中一個偵測到有貨物經過其掃描範圍時，該偵 - 測到貨物的紅外線感測器向控制伺服器發出訊號；控制伺 . 服器根據該訊號控制閱讀器及天線開啟；天線偵測上述貨 物上所安裝的電子標籤的資訊，並將該資訊傳送給閱讀 器；閱讀器將該資訊傳送給控制伺服器；控制伺服器判斷 6 201033906 該貨物是要入庫還是出庫，並將該資訊記錄到一個庫存系 _ 統中；當上述兩個外線感測器中的另一個偵測到有貨物經 過其掃描範圍時，該另一個紅外線感測器向控制伺服器發 • 出訊號；及控制伺服器根據該訊號控制閱讀器及天線關閉。 相較於習知技術，本發明所提供之倉庫管理系統及方 法只需要一個RFID天線，因此可以降低成本。此外，利 用紅外線感測器控制RFID閱讀器及天線的開啟與關閉， 節省了資源，並且可以準確地判斷貨物的入庫與出庫。 ®【實施方式】 參閱圖2所示，係本發明倉庫管理系統較佳實施方式 的硬體架構圖。該系統的硬體架構圖主要包括控制伺服器 1，RF1D閱讀器（下稱閱讀器）2，RFID天線（下稱天線） 3，紅外線感測器5、6，及倉庫管理伺服器7。 所述紅外線感測器5、6用於偵測貨物的出庫或者入 庫，其分別置於倉庫的門内及門外。本實施例中，紅外線 φ 感測器5置於倉庫的門内，紅外線感測器6置於倉庫的門 外。當該紅外線感測器5、6偵測到有貨物經過其掃描範圍 時，向控制伺服器1發出訊號，告訴控制伺服器1可能有 貨物要入庫或者出庫。 所述的控制伺服器1用於接收紅外線感測器5、6發 、 出的訊號，根據該訊號控制閱讀器2及天線3的開啟與關 . 閉。該控制伺服器1還用於接收出庫或者入庫的貨物的基 本資訊，將該貨物的基本資訊記錄到倉庫管理伺服器7中 的庫存系統中。 7 201033906 所述的閱讀器2及天線3在控制伺服器1的控制下開 _ 啟或者關閉。當閱讀器2及天線3在開啟狀態時，可以透 • ‘ 過射頻訊號自動識別安裝有RFID電子標籤（下稱電子標 * 籤）的貨物，並獲取該電子標籤的資訊。所述電子標籤的 資訊係指儲存於該電子標籤中的、該電子標籤所安裝的貨 物的基本資訊，包括貨物名稱、料號、生產廠商、產地等。 所述的倉庫管理伺服器7用於儲存貨物的基本資訊。 本發明的另一個實施例中，該倉庫管理伺服器7與上述控 ® 制伺服器1的功能可以集成在一台伺服器中。 參閱圖3所示，係圖2中控制伺服器1的功能模組圖。 該控制伺服器1主要包括紅外線訊號接收模組10,識別模 組11，控制模組12，貨物資訊接收模組13，及記錄模組 14 ° 所述的紅外線訊號接收模組10用於接收紅外線感測 器5、6發出的訊號，該訊號表示紅外線感測器5或者紅外 ^ 線感測器6偵測到有貨物經過其掃描區域。 所述的識別模組11用於識別所接收的訊號是哪一個 紅外線感測器傳送的，以判斷所掃描的貨物是要出庫還是 入庫。若紅外線訊號接收模組10先接收到紅外線感測器5 發出的訊號，則該識別模組11判斷該貨物是要出庫的，否 * 則，若紅外線訊號接收模組10先接收到紅外線感測器6 . 發出的訊號，則該識別模組11判斷該貨物是要入庫的。 所述的控制模組12用於控制閱讀器2及天線3的開 啟與關閉。在本實施例中，在閱讀器2及天線3關閉的情 201033906 況下’當紅外線訊號接收模組10接收到紅外線感測器5 或紅外線感測器6發出的訊號時’控制模組12開啟閱讀器 • 2及天線3;以及當紅外線訊號接收模組1〇接收到紅外線 感測器5及紅外線感測器6各自發出的訊號時，控制模組 12關閉閱讀器2及天線3。詳細地，若紅外線感測器5掃 描到了貨物的經過，而紅外線感測器6沒有掃描到貨物的 經過，則說明有貨物要出庫，但是還沒有被運出倉庫門口， φ 因此，需要開啟閱讀器2及天線3,讀取該貨物上的電子 標籤資訊。若紅外線感測器5掃描到了貨物的經過，之後 紅外線感測器6又掃描到了貨物的經過，則說明貨物已經 出庫完畢，為了節省資源，將閱讀器2及天線3關閉。反 之，若紅外線感測器6掃描到了貨物的經過，而紅外線感 測器5沒有掃描到貨物的經過，則說明有貨物要入庫，但 是還沒有被運進倉庫門口，因此，需要開啟閱讀器2及天 線3讀=該貨物上的電子標籤資訊。若紅外線感測器6掃 春描到了貨物的經過之後，紅外線感測器5又掃描到了貨物 的經過，則說明貨物已經入庫完畢，為了節省資源，將閱 讀器2及天線3關閉。 所述的資訊接收模組13用於接收閱讀器2傳送的貨 物上所安裝的電子標籤資訊，根據該資訊得到該出庫或者 入庫的貨物的基本資訊。 ^ • 所述的記錄模組14用於將該貨物出庫或者入庫資 訊’及/或該貨物的基本資訊記錄到倉庫管理祠服器7的庫 存系統中。 9 201033906 參閱圖4所示，係本發明倉庫管理方法較佳實施例的 實施流程圖。 ’ 步驟S10,用戶開啟紅外線感測器5、6及控制伺服器 ' 1 ° 步驟S11，紅外線感測器5及紅外線感測器6偵測是 否有物體經過其掃描範圍。 若沒有偵測到物體經過其掃描範圍，則返回步驟 S11，繼續偵測。 ® 否則，若紅外線感測器5或者紅外線感測器6偵測到 物體經過了其掃描範圍，則步驟S12，該紅外線感測器5 或者紅外線感測器6向控制伺服器1發送訊號，使其控制 開啟閱讀器2及天線3。為了便於以下描述，本實施例中， 假設紅外線感測器5偵測到了物體經過其掃描範圍。上述 所述物體有可能是安裝有電子標籤的貨物，也可能是其他 的物品或者人。 g 步驟S13，天線3偵測該物體是否安裝有電子標籤。 若該物體上安裝有電子標籤，則說明該物體是有待出 庫或者入庫的貨物，轉入執行下述步驟S14，或者，若該 物體上沒有安裝電子標籤，則說明該物體是其他的物品或 者人，返回執行上述步驟S11。 步驟S14，天線3將偵測到的電子標籤的資訊傳送給 . 閱讀器2。 步驟S15，閱讀器2將該電子標籤資訊傳送給控制伺 服器1。 10 201033906 步驟S16，控制伺服器1判斷該貨物是要入庫還是出 •庫。其中，若是紅外線感測器5先偵測到有物體經過其掃 ·' 描範圍，並向控制伺服器1發出的訊號，則控制伺服器1 - 判斷該貨物是要出庫，否則，若是紅外線感測器6先偵測 到有物體經過其掃描範圍，並向控制伺服器1發出的訊 號，則控制伺服器1判斷該貨物是要入庫。進一步地，在 步驟S16中，控制伺服器1將該貨物的出庫或者入庫資 訊，及/或該貨物的基本資訊，即上述電子標籤的資訊，記 ® 錄至倉庫管理伺服器7的庫存系統中。 步驟S17,另一個紅外線感測器，即本實施例中的紅 外線感測器6偵測是否有物體經過其掃描範圍。 若沒有物體經過紅外線感測器6的掃描範圍，則返回 步驟S17，繼續偵測，或者，若偵測到有物體經過紅外線 感測器6的掃描範圍，則轉入執行下述步驟S18。 步驟S18，該紅外線感測器6向控制伺服器1發送訊 ^ 號，使其控制關閉閱讀器2及天線3。 以上所述僅為本發明之較佳實施例而已，且已達廣泛 之使用功效，凡其他未脫離本發明所揭示之精神下所完成 之均等變化或修飾，均應該包含在下述之申請專利範圍内。 【圖式簡單說明】 • 圖1係傳統的採用RFID技術實現倉庫管理的系統硬 體架構圖。 圖2係本發明倉庫管理系統較佳實施方式的硬體架構 圖0 11 201033906 圖3係圖2所示伺服器的功能模組圖。 圖4係本發明倉庫管理方法較佳實施例的實施流程 圖。 • 【主要元件符號說明】 控制伺服器 1 紅外線訊號接收模組 10 識別模組 11 控制模組 12 貨物資訊接收模組 13 記錄模組 14 12Frequency Identification (radio frequency identification) technology replaces bar code technology. The RFID technology is a non-contact automatic identification technology, which automatically recognizes target objects and acquires related data through radio frequency signals, and recognizes that the work does not require manual participation and can work in various harsh environments. RFID is mainly composed of three parts: electronic tags, antennas and readers. The electronic tag (4) is composed of components and wafers, which are installed on the goods and can be used to store basic information of the goods. The antenna (4) reads the electronic tag and sends it to the reader' or for the finger issued by the reader. Electronic standard wear. The reader is used to receive and process the electronic tag or send information to the electronic tag. Generally, there are two interfaces. When the reader reads the information of the electronic tag, he can know at the same time which information the electronic money is. 4 201033906 Using RFID technology, you can use barcodes. However, this will be produced. When the f industry goes to (4) the information on the electronic tag on the goods, is it to read the goods on the warehouse or out of the warehouse? Solve this problem. 2. The electronic method that the goods are to be read into the legal system usually has two Kind, the first one, the reference, if there is no 目^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Broken in ': library circle: set me a solid antenna 3, when the antenna 3 outside the door reads the cargo reader 2 first, you can judge that the goods are to be stored in the warehouse; The more the main eve information, every time you read a signing information, you have to compare all the information in the inventory secret:: the efficiency is very low, and will give the inventory system the health (four) to bear. Method to determine the inbound or outbound cargo, rfid reader 2 and antenna 3, 4 Whether there is goods in and out or no goods in and out must always be in the open state 'This will inevitably lead to waste of resources, such as wasting power and loss of RFID equipment, reducing the life of RFID equipment. [Invention] _ Content, it is necessary to propose a warehouse management system and method, which uses an infrared sensor to control the opening of the RFID reader and the antenna 201033906 and shut down, saves resources, and can accurately determine the inbound and outbound storage of the goods. A management system that uses radio frequency identification technology to manage the delivery and storage of goods and materials. The system includes an electronic tag, an antenna, and a reader. The system further includes: a first infrared sensor placed in the warehouse door and placed outside the warehouse door a second infrared sensor for detecting whether a cargo passes through a scanning area of the infrared sensor and sends a signal when a cargo passes; and a control server for receiving the signal sent by the infrared sensor ®, according to the signal to control the reader and antenna to open and close, receive the library or into The information of the electronic tag installed on the goods is judged according to the order of the signals sent by the infrared sensors, whether the goods are to be put into the warehouse or not, and the above information is recorded into an inventory system. The utility model utilizes radio frequency identification technology to manage the outbound and warehousing of the goods. The radio frequency identification includes an electronic tag, an antenna and a reader. The method comprises: preparing a control server and two infrared Φ line sensors, wherein the first The infrared sensor is placed in the warehouse door, and the second infrared sensor is placed outside the warehouse door; the two infrared sensors and the control server are turned on; the first infrared sensor and the second infrared sensor detect whether The goods pass through the scanning range; when one of the two infrared sensors detects that the goods have passed the scanning range, the infrared sensor that detects the goods sends a signal to the control server; The server controls the reader and the antenna to be turned on according to the signal; the antenna detects the electricity installed on the cargo The information of the sub-tag and transmit the information to the reader; the reader transmits the information to the control server; the control server judges 6 201033906 whether the goods are to be put in or out of the warehouse, and the information is recorded to an inventory system. When the other of the two external line sensors detects that the goods have passed the scanning range, the other infrared sensor sends a signal to the control server; and the control server controls the reading according to the signal. The antenna and antenna are turned off. Compared with the prior art, the warehouse management system and method provided by the present invention only requires one RFID antenna, thereby reducing the cost. In addition, the infrared sensor is used to control the opening and closing of the RFID reader and the antenna, which saves resources and can accurately determine the inbound and outbound goods. ® [Embodiment] Referring to Figure 2, there is shown a hardware architecture diagram of a preferred embodiment of the warehouse management system of the present invention. The hardware architecture diagram of the system mainly includes a control server 1, an RF1D reader (hereinafter referred to as a reader) 2, an RFID antenna (hereinafter referred to as an antenna) 3, an infrared sensor 5, 6, and a warehouse management server 7. The infrared sensors 5, 6 are used to detect the outbound or inbound storage of the goods, which are respectively placed inside and outside the door of the warehouse. In this embodiment, the infrared φ sensor 5 is placed in the door of the warehouse, and the infrared sensor 6 is placed outside the door of the warehouse. When the infrared sensor 5, 6 detects that the goods have passed the scanning range, it sends a signal to the control server 1, telling the control server 1 that there may be goods to be stored or unloaded. The control server 1 is configured to receive signals from the infrared sensors 5 and 6, and control the opening and closing of the reader 2 and the antenna 3 according to the signals. The control server 1 is further configured to receive basic information of the goods in the warehouse or the inbound, and record the basic information of the goods into the inventory system in the warehouse management server 7. 7 The reader 2 and the antenna 3 described in 201033906 are turned on or off under the control of the control server 1. When the reader 2 and the antenna 3 are turned on, the goods can be automatically identified by the RFID signal (hereinafter referred to as an electronic label), and the information of the electronic label can be obtained. The information of the electronic tag refers to the basic information of the goods stored in the electronic tag, including the name of the goods, the item number, the manufacturer, the place of origin, and the like. The warehouse management server 7 is used to store basic information of the goods. In another embodiment of the present invention, the functions of the warehouse management server 7 and the above-described control server 1 can be integrated into one server. Referring to FIG. 3, it is a functional module diagram of the control server 1 in FIG. The control server 1 mainly includes an infrared signal receiving module 10, an identification module 11, a control module 12, a cargo information receiving module 13, and a recording module 14°. The infrared signal receiving module 10 is configured to receive infrared rays. The signal from the sensors 5, 6 indicates that the infrared sensor 5 or the infrared sensor 6 detects that the goods have passed through its scanning area. The identification module 11 is configured to identify which infrared sensor is transmitted by the received signal to determine whether the scanned product is to be outbound or inbound. If the infrared signal receiving module 10 first receives the signal from the infrared sensor 5, the identification module 11 determines that the goods are to be out of the library, and if no, the infrared signal receiving module 10 first receives the infrared sensing. The signal sent by the identification module 11 determines that the goods are to be stored. The control module 12 is used to control the opening and closing of the reader 2 and the antenna 3. In this embodiment, when the reader 2 and the antenna 3 are turned off, the control module 12 is turned on when the infrared signal receiving module 10 receives the signal from the infrared sensor 5 or the infrared sensor 6. The reader 2 and the antenna 3; and when the infrared signal receiving module 1 receives the signals from the infrared sensor 5 and the infrared sensor 6, the control module 12 turns off the reader 2 and the antenna 3. In detail, if the infrared sensor 5 scans the passage of the goods, and the infrared sensor 6 does not scan the goods, it indicates that the goods are to be taken out of the warehouse, but have not been shipped out of the warehouse door, φ therefore, it is necessary to open the reading. The device 2 and the antenna 3 read the electronic tag information on the goods. If the infrared sensor 5 scans the passage of the goods, and then the infrared sensor 6 scans the passage of the goods, it indicates that the goods have been discharged, and in order to save resources, the reader 2 and the antenna 3 are turned off. On the other hand, if the infrared sensor 6 scans the passage of the goods, and the infrared sensor 5 does not scan the goods, it indicates that the goods are to be put into the warehouse, but have not been transported into the warehouse door. Therefore, the reader needs to be turned on 2 And antenna 3 read = electronic label information on the goods. If the infrared sensor 6 scans the passage of the goods, the infrared sensor 5 scans the passage of the goods, indicating that the goods have been stored, and in order to save resources, the reader 2 and the antenna 3 are turned off. The information receiving module 13 is configured to receive the electronic tag information installed on the goods transmitted by the reader 2, and obtain basic information of the goods that are outbound or inbound according to the information. ^ The recording module 14 is used to record the goods outbound or inbound information' and/or the basic information of the goods into the inventory management system of the warehouse management server 7. 9 201033906 Referring to Figure 4, there is shown a flow chart of a preferred embodiment of the warehouse management method of the present invention. Step S10, the user turns on the infrared sensors 5, 6 and controls the servo '1 ° step S11, and the infrared sensor 5 and the infrared sensor 6 detect whether an object has passed the scanning range. If it is not detected that the object has passed the scanning range, it returns to step S11 to continue the detection. ® Otherwise, if the infrared sensor 5 or the infrared sensor 6 detects that the object has passed the scanning range, the infrared sensor 5 or the infrared sensor 6 sends a signal to the control server 1 in step S12, so that It controls the reader 2 and the antenna 3 to be turned on. In order to facilitate the following description, in the present embodiment, it is assumed that the infrared sensor 5 detects that the object has passed its scanning range. The object mentioned above may be a cargo with an electronic tag installed, or it may be another article or person. g Step S13, the antenna 3 detects whether the object is equipped with an electronic tag. If the electronic tag is installed on the object, it indicates that the object is a cargo to be taken out or stored, and the process proceeds to step S14 described below, or if the electronic tag is not installed on the object, the object is another article or person. Go back and perform step S11 above. In step S14, the antenna 3 transmits the information of the detected electronic tag to the reader 2. In step S15, the reader 2 transmits the electronic tag information to the control server 1. 10 201033906 Step S16, the control server 1 determines whether the goods are to be stored or exported. Wherein, if the infrared sensor 5 first detects that an object has passed the scanning range and sends a signal to the control server 1, the control server 1 - determines that the goods are to be taken out, otherwise, if it is infrared The detector 6 first detects that an object has passed its scanning range and sends a signal to the control server 1, and the control server 1 judges that the goods are to be stored. Further, in step S16, the control server 1 records the outbound or inbound information of the goods, and/or the basic information of the goods, that is, the information of the electronic tags, into the inventory system of the warehouse management server 7. . In step S17, another infrared sensor, i.e., the infrared sensor 6 in this embodiment, detects whether an object has passed its scanning range. If no object passes the scanning range of the infrared sensor 6, the process returns to step S17 to continue the detection, or if an object is detected to pass the scanning range of the infrared sensor 6, the process proceeds to the following step S18. In step S18, the infrared sensor 6 sends a signal to the control server 1 to control the reader 2 and the antenna 3 to be turned off. The above is only the preferred embodiment of the present invention, and has been used in a wide range of ways. Any other equivalent changes or modifications which are not departing from the spirit of the present invention should be included in the following claims. Inside.
