Description

無線射頻辨識讀取裝置與其功率設定方法 Radio frequency identification and reading device and its power setting method

本發明係關於無線射頻辨識,特別係關於無線射頻辨識讀取裝置與其功率設定方法。 The present invention relates to radio frequency identification, and more particularly to radio frequency identification reading device and its power setting method.

無線射頻辨識(RFID,Radio Frequency Identification)系統是現代貨品或倉儲管理的利器。無線射頻辨識的讀取裝置可以透過無線射頻信號,讀取商品上的主動式或被動式無線射頻辨識標籤所記載的訊息,再把所讀到的訊息對資料庫進行存取,以便快速完成進貨、銷貨、點貨、與/或結帳的動作。 Radio Frequency Identification (RFID) system is a powerful tool for modern goods or warehouse management. The radio frequency identification reading device can read the information recorded on the active or passive radio frequency identification tag on the product through the radio frequency signal, and then access the read information to the database to quickly complete the purchase, The actions of selling, ordering, and/or checkout.

讀取裝置必須適應各式各樣的讀取場景。舉例而言,在大賣場或是大型倉儲的貨品閘口,可以設置大型的門式關口供貨車或是堆高機進出。在門式關口的兩側與上下兩方可以設置一或多個天線,讀取裝置可以一次讀取在貨車或堆高機貨棧上的大量物品的多個標籤訊息。由於門式關口的尺寸較大,可能有數公尺寬高,因此所發出的無線射頻信號的強度需要加強。 The reading device must adapt to various reading scenarios. For example, in the goods gates of hypermarkets or large warehouses, large gated gate delivery vehicles or stackers can be set up to enter and exit. One or more antennas can be installed on both sides and upper and lower sides of the door gate, and the reading device can read multiple tag information of a large number of items on the truck or the stacker at one time. Due to the large size of the door gate, which may be several meters wide and high, the intensity of the radio frequency signal sent out needs to be strengthened.

另一個場景可能為瑕疵物品的檢修台。檢修員可以使用桌面上設置的讀取裝置,或是手持讀取裝置來讀取單一個瑕疵物品。由於檢修台上可能置放了其他瑕疵物品或已經修復好的物品,如果桌面型或手持型 的讀取裝置發出了過強的無線射頻信號,可能會讀取到不想要讀取的物品的無線射頻辨識標籤,使得檢修員無所適從。 Another scenario might be an inspection platform for defective items. The maintenance worker can use the reading device set on the desktop or the hand-held reading device to read a single defective item. Since other defective items or items that have been repaired may be placed on the inspection table, if the desktop type or handheld type The reading device sent out an excessively strong radio frequency signal, which may read radio frequency identification tags of items that you don’t want to read, making the maintenance staff at a loss.

換言之,從上述兩個較為極端的使用情境可以了解到,如果能夠容易調整無線射頻信號的輸出功率,將可以大幅地便利讀取裝置的使用,以適用於各種使用情境,進而改善使用者經驗。 In other words, it can be understood from the above two more extreme usage scenarios that if the output power of the radio frequency signal can be easily adjusted, the use of the reading device can be greatly facilitated to adapt to various usage scenarios, thereby improving user experience.

When the application processor 210 detects that the user touches the first button or touch button, it will set the power to the next larger setting parameter. When there is no larger setting parameter, the power remains unchanged. When the application processor 210 detects that the user touches the second button or touch button, it will set the power to the next smaller setting parameter.

When the knob is rotated in the first direction, the knob can issue commands to the first universal I/O interface, which can increase the setting parameters of the radio frequency signal power. When the knob is rotated in the second direction, the knob can issue commands to the second universal I/O interface, which can reduce the setting parameters of the radio frequency signal power.

However, in an embodiment, as shown in FIG. 2, the application processor 210 may directly cause the radio frequency front-end transceiver circuit 130 to adjust the power of the front-end power amplifier. Generally speaking, since the power range that can be adjusted by the back-end power amplifier is smaller than the power range that can be adjusted by the front-end power amplifier, the application program of the application processor 210 can decide which power to adjust according to the amount of power to be adjusted. One power amplifier, or decide to adjust two power amplifiers.

The barcode reading device The setting can switch the above-mentioned N power setting parameters through a universal I/O interface. After the barcode reading device reads and recognizes the barcode equivalent to a single button, the application program executed by the application processor 210 receives the corresponding switching command from the barcode reading device and sets the power Go to the next setting parameter among the N setting parameters. Or after the barcode reading device sends a character string, the application program executed by the application processor 210 interprets the switching command represented by the character string, and then sets the power to the next setting among the N setting parameters parameter. In other words, every time the barcode is scanned, the setting parameter will be switched to the next one.

Suppose there are N setting parameters arranged in order of power level, and N is a positive integer greater than one. After the barcode reading device reads and recognizes the first type of barcode, the application processor 210 receives the corresponding switching instruction from the barcode reading device, and sets the power to the next larger setting parameter . When there is no larger setting parameter, the power remains unchanged. After the barcode reading device reads and recognizes the second type of barcode, the application program executed by the application processor 210 receives the corresponding switching instruction from the barcode reading device and sets the power to the next Smaller setting parameters. When there is no smaller setting parameter, the power remains unchanged. Or after the barcode reading device sends out the character string, the application program executed by the application processor 210 interprets the switching instruction that the setting parameter represented by the character string becomes larger or smaller, and then sets the power to N The next setting parameter among the setting parameters becomes larger or smaller.

在某一範例當中,具有N種條碼。假定有N個以功率大小依序排列的設定參數,N為大於一的正整數,每種條碼對應到一種設定參數。 當該條碼讀取裝置讀取並且辨識出上述第X種條碼之後(X為介於1與N之間的正整數),該應用程式處理器210所執行的應用程式收到該條碼讀取裝置傳來的相應切換指令,會將功率設定到第X個設定參數。或者是當該條碼讀取裝置送出字串之後,該應用程式處理器210所執行的應用程式解譯出該字串所代表的第X種設定參數的切換指令,接著將功率設定到N個設定參數當中的第X個設定參數。 In a certain example, there are N types of barcodes.

Or after the barcode reading device sends a character string, the application program executed by the application processor 210 interprets the switching command of the Xth setting parameter represented by the character string, and then sets the power to N settings The Xth setting parameter among the parameters.

在一範例當中,具有某種條碼,其解譯出來的字串符合某一種用於調整功率的格式,該格式包含了上述的X值,亦即對應到N個設定參數當中的第X個設定參數。該條碼讀取裝置或該應用程式處理器210所執行的應用程式可以用於解析該格式的字串以取得N值。接著,該應用程式處理器210所執行的應用程式會將功率設定到第X個設定參數。 In one example, there is a certain barcode, and the decoded string conforms to a format used to adjust power. The format includes the above X value, which corresponds to the Xth setting among the N setting parameters parameter. The barcode reading device or the application program executed by the application processor 210 can be used to parse the format string to obtain the N value. Then, the application program executed by the application processor 210 will set the power to the Xth setting parameter.

In another example, the application processor 210 may use a percentage to set the power, such as 17.5% of the maximum output power. After the barcode reading device or the application processor 210 can interpret the character string of the barcode, a 17.5% percentage can be obtained. Then, the application processor 210 will set the output power to 17.5% of the maximum output power. In another example, the application processor 210 can directly set the output power value, such as 0.0175 watts. The barcode reading device or the application program executed by the application processor 210 can interpret the barcode string to obtain a power value representing 0.0175 watts.
