Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments; the components of the embodiments of the utility model described and shown in the drawings here can generally be arranged and designed in various different configurations.

[0022] Example 1

[0025] It should be noted that the above-mentioned communication port 100 is a multiplexed port, which means that this port can not only provide power supply but also provide communication function. The multiplexed port generally adopts RS-485 or RS-422. Other ports that can meet the above conditions can also be used.

[0026] In this embodiment, a wired communication electronic tag is proposed. The above technical solution is to solve a series of problems caused by the complicated wiring and transmission process in the electronic tag by using the wired communication port 100. Specifically, through the above wired communication port 100, the port can obtain power and communication at the same time, thereby reducing the cost, safety and maintenance problems caused by the complicated wiring; through the above power module 200, the energy obtained from the wired communication port 100 is converted into the DC power required by the tag circuit, ensuring that the electronic tag has sufficient power supply when working. The power module 200 includes a controller unit and a battery. The two power sources can be used for power supply alone or for powering the tag at the same time, and they are independent of each other and do not affect each other. When the two power sources exist, the external DC24V power is used. At this time, the battery will not power the tag or charge the battery.

[0028] By setting up a wired communication port 100, the power module 200 converts DC power to provide long-term power to the built-in controller unit and battery. The battery does not need to be replaced frequently, thereby reducing long-term maintenance costs. At the same time, the advantages of wired electronic tags are strong anti-interference and good confidentiality, and are used in some application scenarios that require confidentiality.

[0029] Example 2

[0033] RS-485 is a typical serial communication standard. The transmission principle is actually the level inversion principle. The two lines AB complete the recognition of data 0 and 1 by inverting the level at the rate agreed upon by the master and slave during communication. The principle of RS-485 RS-485 uses a pair of differential signal lines for data transmission, that is, the sending end sends positive and negative signals at the same time, and the receiving end recovers the original data by comparing the difference between the two signals.

[0034] RS-422 is a standard serial communication protocol used to transmit data in industrial control systems and long-distance communications. It uses differential signal transmission and has the advantages of strong anti-interference and long transmission distance. The principle of RS-422 RS-422 uses a pair of differential signal lines for data transmission, that is, the transmitter sends positive and negative signals at the same time, and the receiver recovers the original data by comparing the difference between the two signals. This differential transmission method effectively offsets noise and interference and improves the reliability of communication.

The utility model is provided with a detachable battery compartment to facilitate the replacement of aging batteries, and the operation process is simple, saving time and effort, and maintenance is simple, convenient and efficient.

[0037] As a preferred implementation method, refer to Figure 5 As shown, the ink screen 400 also includes a screen driving unit, and the ink screen 400 is electrically connected to the screen driving unit, and the screen driving unit is electrically connected to the control board 300 and the power module 200; the screen driving unit includes a power supply end, which is electrically connected to the output end of the power module and the drain of the second MOS tube U10 through the first inductor L1; two differential signal ends, and a coupling capacitor C25 is electrically connected; one end of the coupling capacitor C25 is electrically connected to the drain of the second MOS tube U10, and the other end is electrically connected to the anode of the clamping diode U17, and the cathode of the clamping diode U17 is grounded; the source and gate of the second MOS tube U10 are electrically connected to the wireless main control chip U4 of the control board 300.

[0039] As an example, see Figures 2 to 5As shown, one end of the wired communication port 100 is rectified by a rectifier bridge to obtain a voltage of about 24V, and the 24V voltage reaches the power module 200; the other end of the wired communication port 100 outputs a differential signal, and the differential signal goes all the way to the wireless main control chip U4 of the control board 300. At this time, the chip triggers the signal to be turned on, so that the first current limiting resistor R1 can be grounded, that is, the signal can change the connection between the first current limiting resistor R1 and the ground, so that the output voltage of the power module 200 changes, and the feedback voltage of the feedback loop composed of the first voltage-dividing resistor R88 and the second voltage-dividing resistor R89 ​​changes, so that the output of the above-mentioned power management chip U6 changes, thereby adjusting the output, so that the output end of the above-mentioned power module can stably output a 3.3V voltage.

[0041] Example 3

[0042] The embodiment of the utility model provides a wired communication electronic tag, which also includes a shell and a control board 300 arranged in the shell.

[0043] As a preferred implementation, the ink screen 400 can be a 2.9-inch electronic ink screen 400.

These two power supplies can be used separately or to power the tag at the same time, and they are independent of each other and do not affect each other; it should be noted that in the dual power supply working principle, the DC24 power supply and the battery need to be electrically isolated to avoid mutual influence between the power supplies. At the same time, the battery needs to maintain sufficient power to ensure normal power supply in the event of a power failure or power outage; when the utility model has two power sources, the external DC24V power is used. At this time, the battery will not power the tag or charge the battery. When the DC24V external power supply is unplugged, the battery will power the tag; the wired communication electronic tag needs to be used in conjunction with a wireless base station to be used normally. By using button registration, the electronic tag can be operated individually or in batches through a computer. At the same time, the wired communication electronic tag also has a screen with front light function. In some application scenarios where the light is relatively dark, the screen content may not be clearly visible. In this case, the screen needs to have a front light function so that the content on the screen can be clearly seen even when the light is relatively dark. The electronic tag is mainly used in areas such as warehouse shelf picking and finding materials.

[0044] It should be noted that the above-mentioned ink screen 400 can also be of other sizes, and users can choose a suitable screen according to actual needs. For example, when it is necessary to display larger pictures, texts and other information, a 5-inch, 6-inch or larger screen can be used, and users can make flexible replacements.

[0045] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or terminal device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or terminal device including the elements.
