While the transportation device 30 is carrying a luggage bag with an electronic label 60, the electronic label 60 is transported through the power-supply transmission units 14, the message-update transmission unit 16 and the detection device 20 in sequence. The electronic label 60 is an electronic-paper label having a display screen able to present label information.

[0033] Refer to FIG. 1 and FIG. 2 for the practical process of updating the electronic label of the present invention. The electronic-paper label of a luggage bag of a passenger on board is used as an example herein. After the passenger has checked in, the ground service personnel needn’t print an adhesive luggage label but only need to put the luggage bag on the transportation device 30. Then, the luggage label can be updated. In the process of updating the electronic label of the present invention, the luggage bag is placed on the transportation device 30 firstly. Next, the transportation device 30 is started to move the luggage bag and the electronic label 60. While the electronic label 60 passes through the article sensor 50, the article sensor 50 senses the electronic label 60 and generates an article message indicating that an article is detected and then transmits the article message to the controller 12. Next, the controller 12 controls the power-supply transmission units 14 and the message-update transmission unit 16 to respectively send out charging signals and a message updating signal.

[0034] Next, the transportation device 30 continues to transport the electronic label 60 to pass through the plurality of power-supply transmission units 14 in sequence. Next, the charging signals respectively sent out by the power-supply transmission units 14 are transmitted to the electronic label 60 to charge the electronic label 60.

[0035] The charging efficiency is influenced by the distance between the power-supply transmission unit 14 and the electronic label 60, the transportation speed of the transportation device 30, and the number of the power-supply transmission units 14. Refer to FIG. 3. For example, in the case that the vertical distance between the power-supply transmission unit 14 and the electronic label 60 is 50 cm, while the transportation speed is 139.13 cm/sec, the optimized embodiment has 4 power-supply transmission units 14. Refer to FIG. 4. For example, in the case that the vertical distance A between the power-supply transmission unit 14 and the electronic label 60 is 80 cm, while the transportation speed is 76.74 cm/sec, the optimized embodiment has 4 power-supply transmission units 14.

[0036] Refer to FIG. 1 and FIG. 2 once again. After the charging signals are transmitted to the electronic label 60 through the power-supply transmission units 14, the transportation device 30 transports the electronic label 6 to pass through the message-update transmission unit 16, whereby the electronic label 60 can receive the message updating signal to update the label information presented on the electronic label 60.

[0037] Then, the transportation device 30 continues to transport the electronic label 60 to the detection device 20 at the termination end 34. The controller 12 controls the detection device 30 to capture the picture presented by the electronic label 60 to pick up the label information and generate label content information. Next, the detection device 30 transmits the label content information to the controller 12. Next, the controller 12 retrieves the update comparison information from the database 18 to compare the label content information with the update comparison information. If the label content information is different from the update comparison information, the controller 12 generates an alert message and transmits the alert message to the alert device 40 to make the alert device 40 present an audio alert or a video alert to remind the ground service personnel of the updating error of the electronic label 60. In one embodiment, while the controller 12 finds that the label content information is different from the update comparison information, the controller 12 automatically controls the transportation device 30 to send the electronic label 60 located at the termination end 34 back to the start end 32; then, the controller 12 instructs the transportation device 30 to transport the electronic label 60 to pass through the power-supply transmission units 14 and the message-update transmission unit 16 and let the power-supply transmission units 14 and the message-update transmission unit 16 transmit the charging signals and the message updating signal lest the electronic label 60 be updated incompletely.

[0038] Refer to FIG. 5 for another embodiment of the present invention. The electronic-paper label of a luggage bag of a passenger on board is also used as an example herein.

In the embodiment shown in FIG. 5, the label information of the electronic label 60 carried by a luggage bag 62 is updated at a fixed place, wherein the power-supply transmission unit 14 and the message-update transmission unit 16 are respectively disposed at two sides of the luggage bag 62.

[0040] In the electronic label updating process of the embodiment shown in FIG. 5, the controller 12 uses the power-supply transmission unit 14 to transmit the charging signal to the electronic label 60 firstly; next, the controller 12 uses the message-update transmission unit 16 to transmit the message updating signal. Thereby, the label information presented on the electronic label 60 is updated.

[0041] Next, the controller 12 controls the detection device 20 to capture the picture presented by the electronic label 60 and transmit the label content information to the controller 12. Next, the controller 12 retrieves the update comparison information from the database 18 and compares the label content information with the update comparison information. If the label content information is different from the update comparison information, the controller 12 generates an alert message and transmits the alert message to the alert device 40 to make the alert device 40 generate an audio alert or a video alert to remind the ground service personnel of the updating error of the electronic label 60.

[0042] If the picture presented by the electronic label 60 is correct, the luggage bag 62 is placed on the transportation device 30 and transported to the rear end where the administration of the luggage bags is undertaken.

[0043] In conclusion, the present invention adopts a fully automatic data updating technology to simultaneously perform the electric charging operation and information updating operation of the electronic label carried by an article while the article is being transported, whereby to effectively increase the delivery efficiency of logistics.
