由於電子紙顯示幕具有耗電低…次刷新可以長時間顯 不圖案的特點’目前已有利用電子紙來製造電子標籤用 於超市價格標籤’倉庫庫存標牌以及其他標識牌。通常 的超市貨架用電子紙標籤包括-電子紙顯示幕，-電子 紙驅動模組以及-無線射賴別（RFID)模組外部讀 寫器通過發送射頻信號將物品的名稱、價格等資料資訊 發送至RFID模組，rfid模組獲取資料後電子紙驅動模組 刷新電子紙顯示幕顯示物品的名稱、價格等資訊。 [0003]但是這種基於RFID技術的電子纸標籤，每一個電子紙標 籤上的顯示内容是使用者根據電子紙標籤放置的位置和 相對應的物品在外部讀寫器上設定的，外部讀寫器讀取 電子紙標籤中RF10模組的電子編碼，然後將使用者預先 設定的顯示内容資訊發送至該電子紙標籤。首先，採用 這種被動式的刷新方式，每個電子紙標籤只能被動接收 外部讀寫？I發送的刷新内容。其次，使用者需要預先根 據每個電子紙標蕺放置的位置和相對應的物品一 一設定 的每個電子紙標籤對應顯示的物品和物品資訊，程式繁 瑣且工作量大，另外出錯幾率也較大。 [0004] 此外普通RFID的射頻識別距離一般為幾十釐米到幾米， 傳輸距離較短，而通常的超市貨架或者倉庫用電子紙標 1013227468-0 顔觀#單编號A〇m 第3頁/共23頁 M436196Since the electronic paper display screen has low power consumption... the second refresh can display the characteristics of the pattern for a long time. At present, electronic paper is used to manufacture electronic labels for supermarket price labels, warehouse inventory signs and other identification cards. The usual electronic shelf labels for supermarket shelves include - electronic paper display screens, - electronic paper drive modules and - wireless radio frequency (RFID) module external readers send information such as the name and price of the item by sending RF signals. To the RFID module, after the rfid module obtains the data, the electronic paper drive module refreshes the electronic paper display screen to display the name and price of the item. [0003] However, the RFID-based electronic paper label, the display content on each electronic paper label is set by the user according to the position where the electronic paper label is placed and the corresponding item is set on the external reader, external reading and writing The device reads the electronic code of the RF10 module in the electronic paper label, and then sends the user-preset display content information to the electronic paper label. First, with this passive refresh method, each e-paper label can only passively receive external reads and writes. The refresh content sent by I. Secondly, the user needs to pre-set the information of the items and articles corresponding to each e-paper label set according to the position where each electronic paper label is placed and the corresponding item. The program is cumbersome and the workload is large, and the probability of error is also higher. Big. [0004] In addition, the RFID recognition distance of ordinary RFID is generally several tens of centimeters to several meters, and the transmission distance is short, and the usual supermarket shelf or warehouse electronic paper label 1013227468-0 Yan Guan #单号A〇m Page 3 / Total 23 pages M436196

Referring to FIG. 7, a content update system 130 for updating information displayed on the electronic tag 103 in the third embodiment of the present invention. In the third embodiment, the wireless communication module 43 of the electronic tag 103 receives the electrical signal containing the bar code information transmitted by the bar code input interface 33, and sends the bar code information and a communication verification password to the main control through the antenna 73. End 83. In this embodiment, the communication verification password is a dynamic password. In other embodiments, the communication verification password may also be a fixed password 0 _2]. In the same manner as the first embodiment, the main control terminal 83 receives the barcode information sent by the wireless communication module 43 and determines the corresponding item according to the barcode information. . 1013227468-0 The main control terminal 83 simultaneously receives the communication verification secret 10120057 production order number A〇101 S 9 pages/total 23 pages M436196 1101.06 gj" correction pin ^ page I. code, and The information of the item corresponding to the received barcode information and the communication verification password are fed back to the electronic tag 103. The wireless communication module 43 of the electronic tag 1〇3 receives the information of the item and the communication verification password, and the wireless communication module 43 verifies whether the communication verification password is consistent with the previous transmission. If yes, the electronic paper driving module 53 According to the information of the item, the content displayed on the electronic paper display screen 13 is refreshed; otherwise, the item information displayed on the electronic paper display screen 13 is not updated, and the electronic paper driving module 53 drives the electronic paper display screen 13 to display an error prompt. [0033] Please refer to FIG. 8 'the content updating method for updating the information displayed on the electronic tag 103 in the third embodiment of the present invention, including the following steps: [0034] Step S31, receiving bar code information of the item. [0035] Step S32' sends the received barcode information and a communication verification password to the main control terminal. [0036] Step S33, the main control terminal 83 receives the barcode information sent by the electronic tag 103, and determines the corresponding item according to the barcode information. [0037] In step S34, the main control terminal 83 feeds back the information of the item determined in step S3 and the communication verification password to the electronic tag 103. [0038] Step S35, the electronic tag 103 receives the information of the article and the communication verification password ‘ and verifies whether the communication verification password is consistent with the previous transmission. If yes, the process proceeds to step S6; if not, the process proceeds to step S7. [0039] Step S36, the electronic paper driving module 53 refreshes the content displayed on the electronic paper display screen 13 according to the information of the item. [0040] Step S37, the electronic paper driving module 53 drives the electronic paper display screen 13 to display a 10120057.
