配合參考圖1及圖2，第一載送板台11由第一接收區21移動至檢測區31。因在移動第一載送板台11的過程中，第一載送板台11之第一側之板台RFID標籤111先通過該RFID讀取器13之天線131，該RFID讀取器13之天線131先讀到第一載送板台11之第一側之板台RFID標籤111。之後，該RFID讀取器13之天線132再讀到第一載送板台11之第一側之板台RFID標籤111。依據上述的讀取組合訊號，該控制器16可判斷第一載送板台11由第一接收區21移動至檢測區31。在一實施例中，該讀取組合訊號包括一移動觸發訊號，係讀取板台RFID標籤之訊號，以此作為移動狀態的移動觸發訊號。Referring to FIGS. 1 and 2, the first carrier stage 11 is moved from the first receiving area 21 to the detection area 31. In the process of moving the first carrier stage 11, the stage RFID tag 111 of the first side of the first carrier stage 11 first passes through the antenna 131 of the RFID reader 13, and the RFID reader 13 The antenna 131 first reads the pallet RFID tag 111 on the first side of the first carrier pallet 11. Thereafter, the antenna 132 of the RFID reader 13 is read again to the pallet RFID tag 111 on the first side of the first carrier pallet 11.

Thereafter, the antenna 131 of the RFID reader 13 is read again to the pallet RFID tag 112 on the second side of the first carrier pallet 11. According to the above-described read combination signal, the controller 16 can determine that the first carrier stage 11 rotates counterclockwise in the detection area 31.

配合參考圖2及圖4，當鋼品41放置在第一載送板台11或第二載送板台12時，因鋼品41會覆蓋板台RFID標籤114或板台RFID標籤124，讀取器13完全讀不到板台RFID標籤114或板台RFID標籤124，只能讀到鋼品RFID標籤411。因此，當讀取器13僅讀到鋼品RFID標籤411，且沒有讀到板台RFID標籤114或板台RFID標籤124時，表示有鋼品在載送板台上，需將其與載送板台進行配對。讀取器13所讀取的該至少一讀取組合訊號包括一配對觸發訊號，該配對觸發訊號係讀取鋼品RFID標籤之訊號，且未讀到板台RFID標籤114或板台RFID標籤124之訊號。Referring to FIG. 2 and FIG. 4, when the steel product 41 is placed on the first carrier tray 11 or the second carrier tray 12, the steel 41 will cover the pallet RFID tag 114 or the pallet RFID tag 124, and read The picker 13 can not read the pallet RFID tag 114 or the pallet RFID tag 124 completely, and can only read the steel RFID tag 411. Therefore, when the reader 13 reads only the steel RFID tag 411 and does not read the pallet RFID tag 114 or the pallet RFID tag 124, it indicates that there is a steel product atOn the carrier plate, it needs to be paired with the carrier plate. The at least one read combination signal read by the reader 13 includes a pairing trigger signal, which reads the signal of the steel RFID tag, and does not read the table RFID tag 114 or the table RFID tag 124. Signal.
若讀取器13讀到鋼品RFID標籤，且讀到板台RFID標籤114或板台RFID標籤124時，表示鋼品RFID標籤是周遭的鋼品，不是放在第一載送板台11或第二載送板台12上的鋼品，無須進行配對處理。If the reader 13 reads the steel RFID tag and reads the pallet RFID tag 114 or the pallet RFID tag 124, it means that the steel RFID tag is the surrounding steel, not placed on the first carrier plate 11 or The steel on the second carrier table 12 does not need to be paired.
本發明之載送板台移動識別系統10另包括二接收區RFID讀取器14、15，分別設置於二接收區21、22。其中，第一接收區RFID讀取器14設置於第一接收區21的第二側，第二接收區RFID讀取器15設置於第一接收區22的第二側。The carrier table movement recognition system 10 of the present invention further includes two receiving area RFID readers 14, 15 disposed in the two receiving areas 21, 22, respectively. The first receiving area RFID reader 14 is disposed on the second side of the first receiving area 21, and the second receiving area RFID reader 15 is disposed on the second side of the first receiving area 22.
參考圖6，當第一載送板台11移入檢測區31時，沒有鋼品在第一載送板台11上，且又旋轉朝向第二側(倉庫側)，之後讀取器13之天線131及天線132均讀到鋼品RFID標籤。且先前的第一接收區RFID讀取器14及第二接收區RFID讀取器15均未讀到鋼品RFID標籤，則表示是由倉庫送出的鋼品放在第一載送板台11上，可將鋼品與該第一載送板台11進行配對處理。Referring to Fig. 6, when the first carrier stage 11 is moved into the detection zone 31, no steel is on the first carrier stage 11, and is rotated toward the second side (warehouse side), after which the antenna of the reader 13 Both the 131 and the antenna 132 read the steel RFID tag. If the previous first receiving area RFID reader 14 and the second receiving area RFID reader 15 do not read the steel RFID tag, it means that the steel sent by the warehouse is placed on the first carrying board 11 The steel product can be paired with the first carrier platen 11.
當第一載送板台11在檢測區31旋轉至第一側(堆高機入口側)，之後移動至第一接收區21時，若第一接收區RFID讀取器14讀到鋼品RFID標籤及第一載送板台11之板台RFID標籤，便可再次確認該第一載送板台11上的鋼品是由倉庫送出的鋼品。When the first carrier plate 11 is rotated to the first side (the stacker inlet side) of the detection zone 31 and then moved to the first receiving zone 21, if the first receiving zone RFID reader 14 reads the steel RFID The label and the pallet RFID tag of the first carrier pallet 11 can reconfirm that the steel on the first carrier pallet 11 is a steel product sent from the warehouse.
在一實施例中，該鋼品RFID標籤儲存一鋼品身份碼及一鋼品類別碼。該板台RFID標籤儲存一板台編號、一板台類別碼及一位置識別碼。因此，讀取器可藉由讀取的RFID標籤內所儲存的資料判斷是鋼品RFID標籤或是板台RFID標籤。In one embodiment, the steel RFID tag stores a steel identification code and a steel category code. The board RFID tag stores a board number, a board category code and a location identifier. Therefore, the reader can determine whether it is a steel RFID tag or a pallet RFID tag by reading the data stored in the RFID tag.
本發明之實施例中，利用所讀到載送板台上所裝設之RFID標籤的訊號，即可推測出該載送板台上是否有鋼品存在、載送板台的移動方向以及其轉動方向等資訊，經實務驗證後，本系統之準確度接近100%。本發明載送板台移動識別系統利用分析和處理讀取組合訊號，即可準確判定出鋼品與載送板台之配對資訊，以及其移動之狀態。In the embodiment of the present invention, the RFID tag installed on the carrier plate is read.The signal can be inferred whether there is steel on the carrier plate, the direction of movement of the carrier plate and the direction of its rotation. After the actual verification, the accuracy of the system is close to 100%. The carrier plate mobile identification system of the present invention can accurately determine the pairing information of the steel product and the carrier plate and the state of its movement by analyzing and processing the combined signal.
本發明載送板台移動識別系統可解決鋼品在入庫時，周遭鋼品RFID標籤的干擾以及移動過程中之狀態判別等技術瓶頸，讓倉庫在鋼品入庫得以實現自動化作業的目標。本發明載送板台移動識別系統可有效識別鋼品身份與載送板台編號外，亦可用以偵測載送板台的位置、移動方向以及轉動狀態等資訊，並將此資訊提供給接收系統整合應用，以實現自動化作業。The mobile pallet identification system of the invention can solve the technical bottlenecks such as the interference of the steel products in the storage of the steel products and the state discrimination during the movement of the steel products, so that the warehouse can achieve the goal of automatic operation in the steel product storage. The carrier movement identification system of the invention can effectively identify the steel product identity and the carrier plate number, and can also detect information such as the position, moving direction and rotation state of the carrier plate, and provide this information to the receiving. The system integrates applications for automated operations.
惟上述實施例僅為說明本發明之原理及其功效，而非用以限制本發明。因此，習於此技術之人士對上述實施例進行修改及變化仍不脫本發明之精神。本發明之權利範圍應如後述之申請專利範圍所列。However, the above embodiments are merely illustrative of the principles and effects of the invention and are not intended to limit the invention. Therefore, those skilled in the art can make modifications and changes to the above embodiments without departing from the spirit of the invention.
