Meanwhile, it should be understood that in the following description, "circuit" refers to a conductive loop constituted by at least one element or sub-circuit through electrical connection or electromagnetic connection. When an element or circuit is referred to as being "connected to" another element or being "connected between" two nodes, it can be directly coupled or connected to the other element or intervening elements may be present and the connection between the elements may be physical, logical, or a combination thereof. In contrast, when an element is referred to as being "directly coupled to" or "directly connected to" another element, it means that there are no intervening elements present between the two.
Fig. 1 is a schematic structural view of an electronic paper pull ring according to an embodiment of the present invention. FIG. 2 is a schematic circuit diagram of an electronic paper pull ring in accordance with an embodiment of the present invention. As shown in fig. 1, the electronic paper-based smart pull billboard of this embodiment includes a billboard body 1 and an electronic paper assembly 2. Wherein the billboard body 1 has a handle member 11 and a receiving portion 12 suitable for gripping. The electronic paper assembly 2 has an electronic ink screen 21 and a circuit assembly 22 (see fig. 2) electrically connected to each other. The electronic paper assembly is disposed in the housing 12.
Fig. 2 is a schematic circuit diagram of an electronic paper assembly of the electronic paper-based smart-grip billboard of the present embodiment. As shown in fig. 2, the electronic paper assembly 2 includes an electronic ink screen 21 and a circuit assembly 22. The electronic ink display screen is a screen using electronic ink. Electronic ink screens are also known as electronic paper display technology. Electronic ink is a new method and technology for innovating information display. Like most conventional inks, electronic ink and lines to change its color are printable on a variety of surfaces, from curved plastic, polyester film, paper to cloth. The difference from conventional paper is that electronic ink changes color when energized and can display a changing image, such as a calculator or cell phone display. The surface of the electronic ink screen is adhered with a plurality of small-volume 'microcapsules', and black particles with negative electricity and white particles with positive electricity are encapsulated, and particles with different colors are orderly arranged by changing charges, so that a visible black and white effect is presented. The electronic ink screen is composed of two substrates, the electronic ink composed of countless tiny transparent particles is coated on the substrates, the particles are formed by sealing a plurality of black and white particles with positive and negative electricity in an internal liquid microcapsule, and the charged particles with different colors can move in different directions due to different applied electric fields, so that the effect of black or white is presented on the surface of the display screen. Thus, black and white patterns and characters similar to printed matters can be displayed on the surface of the electronic paper, the electronic paper looks very similar to paper, and the reflection phenomenon of traditional liquid crystal display does not exist in sunlight. Meanwhile, only when the color of the pixel changes (for example, black to white), power is consumed, and the picture on the display screen can still be reserved after the power supply is turned off, so that the power is saved.
With the development of technology, electronic ink displays may appear in color in addition to black and white.
Further, the circuit assembly 22 includes a display driving circuit 22a and a wireless communication circuit 22b. The display driving circuit 22a is electrically connected to the electronic ink screen 21, and is used for driving the electronic ink screen to display and refresh. The wireless communication circuit 22b is configured to wirelessly receive advertisement content to be displayed and transmit the advertisement content to the display driving circuit.
In the present embodiment, the wireless communication circuit 22b includes a Lora communication module 22b1 and an LTE CAT1 communication module 22b2. The Long Range Radio (Long Range Radio) is a low power consumption local area network wireless standard created by semtech company. The Lora communication module 22b1 is a hardware communication circuit that performs communication in compliance with the Lora protocol. The transmission distance of the Lora communication module can reach 2-5Km in towns and 15Km in suburban areas. The operating frequency of the antenna is ISM frequency bands including 433, 868, 915MHz and the like. The modulation scheme of Lora is based on spread spectrum technology, a variant of linear modulation spread spectrum (CSS), with Forward Error Correction (FEC) capability. Therefore, the Lora communication module has the characteristics of long distance and low power consumption, but has low data transmission rate. LTE (Long Term Evolution ) is a long term evolution of The UMTS (Universal Mobile Telecommunications System ) technical standard established by The 3GPP (The 3rd Generation Partnership Project, third generation partnership project) organization. LTE CAT1 refers to LTE UE-Category 1, also known as eMTC, or LTE-M. According to the definition of 3GPP, UE-Category is classified into 10 classes in total according to the desired quality of service (QoS, quility of Service). Different CAT categories correspond to different quality of service. The purpose of CAT1 is to serve the internet of things and achieve the purpose of low power consumption and low cost LTE connections. CAT1 has advantages in terms of network coverage, speed and latency compared to NB-IoT and 2G modules. Compared with the traditional CAT4 module, the CAT4 module has the advantages of low cost and low power consumption. Meanwhile, CAT1 is suitable for the current home 4G network, and is very suitable for application scenes requiring cost performance, delay, coverage and communication speed.
In the present embodiment, the display driving circuit 22a and the wireless communication circuit 22b are controlled by a controller (not shown in the figure) to perform reception and display of data. The electronic paper pull ring of the present embodiment may further include a memory (not shown) for storing image data required for carousel.
In the present embodiment, in order to reduce the power consumption, the wireless communication circuit 22b keeps the Lora communication module 22b1 in a low power consumption state in an operating state, while keeping the LTE CAT1 communication module in a power-off state. Thus, the Lora communication module periodically attempts to receive signals, minimizing its own power consumption, while the LTE CAT1 communication module remains completely free of power consumption. The Lora communication module informs the controller after receiving the notification message, and the controller further controls the LTE CAT1 communication module to power up to enter a receiving mode.
