Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-6, as shown in fig. 1-6, a positionable retail price tag includes an electronic ink screen control circuit with an MCU control unit, a bluetooth BLE minimal system circuit based on NRF52832, and a watchdog circuit with power supply voltage monitoring; the electronic ink screen control circuit with the MCU control unit and the Bluetooth BLE minimum system circuit based on the NRF52832 are communicated through a serial port; the watchdog circuit with the power supply voltage monitoring is connected with the electronic ink screen control circuit with the MCU control unit;

the power source of the ink screen control circuit is an external power source;

The utility model discloses for paper price label, can be used repeatedly, environmental protection more. Compared with the traditional electronic tag, the power consumption is lower, one button battery can be used for 5-10 years, and the battery is basically not required to be replaced.

The power source of the ink screen control circuit is an external power source, the power is supplied to the part of the circuit when the content of the electronic ink screen needs to be modified, and the circuit is in a power-off state after the modification is finished.

Under the condition that the electronic ink screen does not need to be modified, only the electronic ink screen control circuit with the MCU control unit works, and data can be sent once every 10 minutes, so that the power consumption of the circuit is extremely low, and the design can continuously work for 5-10 years under the condition of one button battery.

The ink screen control circuit is communicated with external equipment, the content displayed by the electronic ink screen is acquired through UART communication, the data of the part is refreshed on the electronic ink screen, and the part of the circuit can be powered off after the action of refreshing the electronic ink screen is finished; the commodity information is displayed on the electronic ink screen, and the method comprises the following steps: commodity price, commodity name, commodity origin.

The Bluetooth BLE minimum system circuit based on the NRF52832 selects a low-power consumption Bluetooth chip nRF52832 for sending a Beacon broadcast packet, wherein the broadcast packet comprises: the MD5 check code, the Unix timestamp updated by the ink screen, the residual capacity and the RSSI value; when the electric quantity of the battery is reduced to only 10%, the LED status lamp can slowly flash to prompt a user to replace the battery; meanwhile, the Beacon broadcasting packet also contains the information of the residual electric quantity, and the residual electric quantity and the placement position of each electronic price label can be seen at the computer terminal.

The content displayed on the electronic ink screen capable of positioning the retail price label is operated at a computer end, and a common label template is used; the computer is connected with the scanning gun, scans the two-dimensional code and the bar code on the commodity package to obtain product information, and writes the related product information on the label template.

Referring to fig. 7 and 8, as shown in fig. 7 and 8, after the label of the computer end is prepared, the label is transmitted to the mobile phone end through the internet, the mobile phone end transmits the displayed content to the label configurator through WiFi, and after the label configurator receives the information, the information is transmitted to the electronic price label, and the content of the electronic ink screen of the electronic price label and the content of the data packet of Beacon are updated; after the configuration is accomplished, break off the connection between label configurator and the electronic price label, electronic price label only has the Beacon circuit to have button cell this moment, and all circuits of electronic ink screen part do not switch on, so electronic price label's electric quantity only consumes sending the Beacon data package, and the time interval of sending the Beacon data package is once for 10 minutes, so electronic price label's electric consumption is very low during this time, can await the opportune moment for 5~10 years in succession.

Dispose a plurality of bluetooth gateway on the goods shelves in market, the data package that electronic price label sent is received to bluetooth gateway, and this data package includes: the commodity navigation information comprises MD5 check codes of the commodity information, Unix timestamps updated by an ink screen, remaining capacity and RSSI values, the RSSI values are reported to a background server by the Bluetooth gateways, the RSSI values reported by the Bluetooth gateways are received by the background server, and the positions of the electronic price labels are calculated according to the RSSI values, so that the commodity navigation information is generated.

The Bluetooth gateway receives the RSSI value of the electronic price label and the residual electric quantity of the electronic price label, and prompts a user at a computer end and a mobile phone end when the residual electric quantity is less than 10 percent;

the broadcast packet of the electronic price label also comprises an MD5 check code, the value is used for checking whether the content displayed by the electronic ink screen is the same as the content generated by the computer, and when the MD5 check code is incorrect, a worker is informed to check the content displayed by the electronic ink screen again, so that unnecessary disputes caused by wrong price labeling are avoided.

The label configurator is a matched device, uses a special communication line, and has a physical interface of a 3.5mm earphone hole; the tag configurator supplies power to the electronic price tag through the earphone hole, and the power for refreshing the electronic price tag is obtained from the earphone hole; the earphone hole is provided with a full-duplex UART communication module besides a power module, and the full-duplex UART communication module is used for receiving data and configuration feedback of a tag configurator by an electronic price tag; because the electronic ink screen has the characteristic that the display content is not changed when the power is off, the power supply of the electronic price tag can be pulled out after the content of the electronic ink screen is refreshed.

The utility model discloses electronic price label contains two parts of circuits, wherein one part of circuits can be powered down, which is the key point of the product low power consumption; the characteristic that the display content cannot be changed by using the electronic ink screen when the power is off is a key point that the circuit can be powered off; and the Bluetooth gateway is matched for use, so that the commodity positioning and navigation functions are realized.

It is an object of the invention to provide a circuit hardware configuration for positionable retail price labels different from the prior art, enabling the skilled person to achieve further developments in such a configuration.

The utility model has very low power consumption, and one button cell can be used for 5 to 10 years;

the commodity navigation function is realized by using the Bluetooth positioning technology;

whether the information of the electronic price label is synchronized successfully or not can be checked at the Web end of the computer, so that unnecessary transaction troubles are avoided;

the product circuit is simple, the failure rate is low, and the purpose of mass production can be realized;

the electronic price label can be used many times, while the paper price label is disposable and not environment-friendly.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
