When the electronic price tag 100 slides in the sliding slot 210, the power supply rail 240 is in contact with the charging interface 140 to realize electrical connection. The power supply rail 240 may be disposed on any side of the inner wall of the sliding slot 210, for example, the power supply rail 240 may be disposed on the upper side 212 of the inner wall of the sliding slot 210, may be disposed on the lower side 214 of the inner wall of the sliding slot 210, and may be disposed on the back 216 of the inner wall of the sliding slot 210, i.e., the side facing the back of the electronic price tag 100 (i.e., the opposite side of the display screen 110). The power supply rail 240 is located at a position corresponding to the position of the charging interface 140 on the housing 150. In fig. 3B, the power supply rail 240 is described as being disposed on the upper side 212 of the inner wall of the chute 210. The signal circuits of the power supply rail 240 and the charging interface 140 are corresponding and can be coupled together, that is, when the power supply rail 240 and the charging interface 140 are electrically connected in a contact manner, the number and the arrangement positions of the signal circuits inside the power supply rail 240 and the charging interface 140 are in one-to-one correspondence, and can be connected and coupled together in a preset manner.
The communication circuits in the communication interface 120 and the communication rail 220 differ according to the communication protocol. For example, the I2C communication protocol, the UART communication protocol, and the SPI communication protocol are different from each other. However, the communication rail 220 and the power supply rail 240 correspond to the number and arrangement positions of signals in the communication interface 120 and the charging interface 140 in one-to-one correspondence. Taking the I2C communication protocol as an example, the communication interface 120 and the charging interface 140 require at least 4 signal circuits (power VDD, ground GND, clock signal SCL, data signal SDA), each corresponding to one contact. The communication interface 120 and the charging interface 140 require a minimum of 4 contacts for transferring signals and/or voltages, said 4 contacts corresponding to 4 signal circuits, respectively. Specifically, the charging interface 140 may include a high-voltage contact VDD (corresponding to a high-voltage signal VDD) and a low-voltage contact GND (corresponding to a low-voltage signal GND), and the communication interface 120 may include a clock signal contact SCL (corresponding to a clock signal SCL) and a data signal contact SDA (corresponding to a data signal SDA). The plurality of contacts are arranged in parallel at intervals. The communication rail 220 and the power supply rail 240 also comprise 4 signal circuits (power supply VDD, ground GND, clock signal SCL, data signal SDA), the power supply rail 240 comprises a high voltage signal circuit VDD (corresponding to the high voltage signal VDD) and a low voltage signal circuit GND (corresponding to the low voltage signal GND), and the communication rail 220 comprises a clock signal circuit SCL (corresponding to the clock signal SCL) and a data signal circuit SDA (corresponding to the data signal SDA). The arrangement positions of the 4 signal circuits are in one-to-one correspondence with the arrangement positions of the 4 signal circuits in the communication interface 120 and the charging interface 140, and are arranged in parallel at intervals.
The communication rail 220 and the power rail 240 may be juxtaposed on the same side of the side wall inside the chute 210 and spaced apart in parallel. The communication track 220 and the power supply track 240 may also be disposed on different sides of the inner wall of the chute 210. Fig. 3B illustrates an example in which the communication rail 220 and the power supply rail 240 are disposed at an interval in parallel on the upper side of the inner wall of the chute 210. The communication track 220 and the power supply track 240 may be conductive metal materials.
The communication port 260 may be provided on the rail 200. Specifically, the communication port 260 may be provided at an end of the rail 200 in wired communication, i.e., electrical connection, with the communication rail 220. When the electronic price tag system 001 is in operation, the communication port 260 is in wired communication, i.e., electrically connected, with the control device 300, thereby enabling the control device 300 to be in wired communication with the plurality of electronic price tags 100. The communication port 260 may also be provided at other locations on the rail 200, such as the upper side, the lower side, etc. The communication port 260 may also be electrically connected to the power rail 240, and when the rail 200 is in operation, the communication port 260 is electrically connected to an external power source, which may be the control device 300. The communication port 260 may be a general data interface such as a USB interface, a TypeC interface, a UART interface, or the like. The plurality of rails 200 may be electrically connected by wires through the communication ports 260 of each other. The control device 300 may also enable wired communication connections with the plurality of rails 200 and the electronic price tags 100 mounted on the plurality of rails 200 via the communication port 260.
It should be noted that two or more communication ports 260 may be provided on each rail 200. The two or more communication ports 260 are electrically connected to each other. Each communication port 260 may be electrically connected to the communication ports 260 of the other rails 200, or may be electrically connected to the control device 300. Two or more communication ports 260 may be respectively disposed at both ends of the guide rail 200, or may be disposed at other portions of the guide rail 200, for example, an upper side, a lower side, and the like.
In summary, the electronic price tag 100 does not need to be configured with a wireless communication module, a power supply module and a control module, and the electronic price tags 100 can be connected and electrically connected with the guide rail 100 in a wired communication manner, so that one set of wireless communication module, power supply module and control module can be shared, and the hardware cost of the electronic price tag system 001 can be reduced.
The control device 300 may include a hardware device having a data information processing function and a program necessary for driving the hardware device to operate. Of course, the control device 300 may be only a hardware device having a data processing capability, or only a program running in a hardware device. For example, the control device 300 may be a master control circuit or other device that drives the electronic price tag 100 but is independent of the electronic price tag 100. Control device 300 may be communicatively connected to server 500 and receive instruction information transmitted from server 500. The indication information may include commodity information of the target commodity. For example, the indication information may be price information of the target product, coupon information, composition information, production place information, product operation rule information, video identification code, current inventory information of the product, and the like. The indication information may further include a two-dimensional code or a bar code, and the user may scan the two-dimensional code or the bar code through the mobile terminal to obtain detailed information of the at least one commodity. Further, the electronic price tag 100 may also be other electronic devices with a display function, and accordingly, the information may also be other text information or picture information to be displayed. The communication connection refers to any form of connection capable of receiving information directly or indirectly. For example, the server 500 may establish a wireless communication connection with the control device 300 through wireless communication to transfer data with each other; the server 500 may also establish a wired communication connection with the control device 300 through a wired direct connection to transfer data with each other; the server 500 may also communicate data with each other by establishing an indirect wired communication connection with the control device 300 through a direct connection with other circuitry via a wire.
The control device 300 may be in wired communication with the at least one rail 200 and the at least one electronic price tag 100 when the electronic price tag system 001 is in operation. The wired communications connection may be a direct electrical connection or an indirect connection through electrical connection with other circuitry. Specifically, when the electronic price tag system 001 operates, at least one of the rails 200 is electrically connected through a respective communication port 260, thereby implementing a series connection (i.e., daisy chain topology) of the plurality of rails 200. The control device 300 may be in wired communication with the communication port 260 of one of the at least one guide rails 200, thereby enabling wired communication with all of the guide rails 200. The wired communication connection between the rails 200 and the wired communication connection between the control device 300 and the rails 200 can be implemented by means of data lines 004 (shown in fig. 1), such as USB interface data lines, TypeC interface data lines, UART interface data lines, and so on.
Each guide rail 200 is slidably provided with at least one electronic price tag 100, and each electronic price tag 100 is in wired communication connection with the corresponding guide rail 200 through the contact connection of the communication guide rail 220 and the communication interface 120, so that each electronic price tag 100 is in wired communication connection with the control device 300 through the guide rail 200. Therefore, the control device 300 may control all of the electronic price tags 100 wired thereto to control the display screen 110 of at least one electronic price tag 100 to display the indication information. The control device 300 may control the states of operation, display, etc. of the connected electronic price tag 100. The control device 300 may control the modification of the information content displayed on the display screen 110 of the connected electronic price tag 100. The control device 300 may receive the indication information transmitted by the server 500, transmit the indication information to the corresponding electronic price tag 100, and instruct the electronic price tag 100 to display the indication information. The control device 300 may manage all the electronic price tags 100 in the store, and the control device 300 may store the correspondence between all the electronic price tags 100 and the products. Each electronic price tag 100 corresponds to a product. The control device 300 may transmit the indication information to the electronic price tag 100 corresponding to the target product according to the corresponding relationship. Specifically, each electronic price tag 100 includes a corresponding device address therein. The control device 300 may store a correspondence relationship between the device address of each electronic price tag 100 and the corresponding product. The control device 300 may specify the device address of the electronic price tag 100 corresponding to the target product based on the target product included in the instruction information, and drive the electronic price tag 100 corresponding to the target product to display the product information of the target product.
As shown in fig. 1, all the rails 200 on one shelf 002 are connected in series by a wired manner, and the control device 300 is connected to one of the rails 200 by a wired manner, so that the electronic price tag system 001 can realize the control of a plurality of electronic price tags 300 through one control device 300 without providing a control device 300 on each electronic price tag 100, thereby greatly reducing the hardware cost of the electronic price tag system 001 and promoting the popularization of the electronic price tag system 001.
As previously described, the communication port 260 of the rail 200 can be electrically connected not only to the communication rail 220, but also to the supply rail 240. The control device 300 is connected to the electronic price tag 100 through the communication port 260 by wire, and not only can be connected to the electronic price tag 100 through the communication port 260 by wire communication, but also can be used as a power supply to supply power to the electronic price tag 100 through the communication port 260. Specifically, the control device 300 may be externally connected to a power supply to supply power to the electronic price tag 100. Therefore, the electronic price tag system 001 can supply power to the plurality of electronic price tags 100 through one power supply without equipping each electronic price tag 100 with a power supply module, thereby greatly reducing the hardware cost of the electronic price tag system 001 and avoiding inconvenience caused by frequent battery replacement.
