Description
Technical Field
[0001] The utility model relates to the technical field of electronic price tags, in particular to a long strip photovoltaic power generation advertising price tag with a cholesterol liquid crystal screen. Background Art
[0002] In the current electronic price tag market, most of them use electrophoretic electronic paper technology, which can maintain the pattern after power failure to achieve the purpose of energy saving. Due to the characteristics of the screen, light cannot pass through, so it is not convenient to integrate photovoltaic power generation modules. The shielded colors are not rich enough, and the display is not delicate enough. Many small particles can be observed when looking closely. The aspect ratio is generally 2:1 and not more than 3:1. It is only used to display prices and barcodes. When installed, it is uneven on the shelf, affecting the appearance. The area without price tags is not utilized. The cholesterol liquid crystal display can also display when the power is off, and because the screen can transmit part of the light, it makes it possible to integrate photovoltaic panels behind the screen. Therefore, a simple and easy-to-use long photovoltaic advertising price tag based on a cholesterol liquid crystal display that is the same length as an ordinary shelf is needed, so that the price tags look visually uniform after installation, improve the utilization rate of the price tag space, and can integrate photovoltaic power generation behind the screen.
[0003] In view of the above problems, the utility model document proposes a long photovoltaic power generation advertising price tag with a cholesterol liquid crystal screen. Utility Model Content
[0004] The utility model provides a long photovoltaic power generation advertising price tag with a cholesterol liquid crystal screen, which can be displayed when the power is off, has delicate and rich colors, a large aspect ratio, and is adapted to ordinary shelves in the length direction. After installation, it gives a visually uniform feeling. A photovoltaic power generation panel is added behind the screen, and the area of the entire screen is used to collect ambient light to generate electricity. The price tag content and the advertising content are sent to each device through a base station, supporting one-to-many data transmission.
[0005] The utility model provides the following technical solutions:
[0006] A long photovoltaic power generation advertising price tag with a cholesterol liquid crystal screen, comprising:
[0007] The price tag body includes a main shell, on the inner wall of which an independent temperature sensor board, a screen driver board, a main control board and a battery holder are fixedly mounted, a cholesterol liquid crystal display screen used in conjunction with the screen driver board is embedded and mounted at the shell opening of the main shell, a photovoltaic power generation panel for collecting ambient light to generate electricity is fixedly arranged on the back of the cholesterol liquid crystal display screen, and a battery for collecting electricity is arranged in the battery holder.
[0008] In a possible design, the screen driving board and the independent temperature sensor board are connected via FPC 1, the screen driving board and the main control board are connected via FPC 2, and the battery and the main control board are electrically connected via plug-in wires.
[0009] In a possible design, the main control board is provided with an RGB light for indicating the working status.
[0010] In a possible design, a transparent cover plate for protection is provided on the surface of the cholesterol liquid crystal display screen.
[0011] In a possible design, the multiple price tag bodies are connected to the same base station via WIFI, and the base station is connected to a cloud server via 4G or WIFI communication.
[0012] In a possible design, the base station is electrically connected to a power adapter via a plug-in wire.
[0013] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.
[0014] The working principle and usage process of this technical solution are as follows:
[0015] First, the user uploads the information to be displayed (such as product prices, promotional activities, etc.) to the cloud server through an Internet-connected mobile phone or computer. The cloud server receives and stores this information. The cloud server establishes a connection with the base station through a 4G network or WIFI, and remotely transmits the prepared data to the base station. After the base station receives the data, it stores it in the internal memory and waits for it to be sent. The base station sends the internally stored data wirelessly to multiple price tag bodies according to a preset communication protocol (such as 2.4G, WIFI or BLE). Each price tag body has a unique identifier to ensure that the data can be accurately sent to the target price tag. After the price tag body receives the data sent by the base station, the MCU on the main control board parses the data and controls the screen driver board to drive the cholesterol LCD display to display the corresponding information. At the same time, the RGB light lights up according to the system status (such as successful data reception, sufficient power, etc.), providing users with intuitive visual feedback;
[0016] During the operation of the price tag body, the photovoltaic panel continuously collects ambient light and converts it into electrical energy and stores it in the battery. The battery's electrical energy is boosted or bucked by the power management module and stored in the battery to adapt to the working voltage of the main control chip and the corresponding modules. When the mains power supply is interrupted or insufficient, the battery provides power support for the entire system to ensure the continuous operation of the price tag body. The independent temperature sensor board monitors the temperature inside the price tag body in real time and sends the data to the screen driver board or the main control board through the FPC. The system adaptively adjusts the working parameters according to the temperature data to ensure the stable operation of the equipment and extend its service life.
[0017] The utility model has the following beneficial effects:
[0018] The utility model reduces the labor cost of replacing paper advertisements, has rich colors, and provides a good visual experience. The price tags can be expanded to indoor photovoltaic power generation, and there is no need to replace batteries, which reduces maintenance costs. The price tags can be made the same length as ordinary shelves, and after installation, they look neater and more comfortable than ordinary price tags. Advertisements can be displayed in non-price barcode areas, product pictures can be displayed, and the utilization rate of the plane surface can be improved. At the same time, through upper devices such as mobile phones or computers, with certain PC software or mobile phone APP, content batch management can be achieved through the cloud and base stations, and content can be delivered remotely with one click.
[0019] The utility model realizes remote management of advertising price tags and real-time updating of information by communicating with the 4G or WIFI of the base station through the cloud server, greatly improving the management efficiency and information transmission speed. The base station supports multiple wireless communication methods such as 2.4G, WIFI and BLE, and can adapt to different scenes and needs, enhancing the flexibility and applicability of the system; the price tag body adopts photovoltaic power generation technology, which can collect ambient light and convert it into electrical energy, realize self-sufficiency of green energy, reduce operating costs and reduce the impact on the environment; the independent temperature sensor board monitors the internal temperature of the equipment in real time, and adaptively adjusts the working parameters according to the temperature data, ensuring the stable operation of the equipment and extending its service life.
