Description
Technical Field
The utility model relates to a liquid crystal display technology field, in particular to E-INK network structure based on wireless mode of passing through.
Background
E-INK electronic INK displays have many advantages, including readability, flexibility, and low power consumption. The reflectance and contrast of electronic ink is better than other display technologies. They appear like ink on paper, a medium that people feel comfortable reading and handling. The E-INK can be used as an electronic price tag in a supermarket, or can be used as a gate mark in a conference room, a hospital consulting room or an office building office, and the display content (such as the price of the electronic price tag, the ongoing conference introduction in the conference room, the hospital consulting room introduction and the like) of the E-INK display screens needs to be modified by an upper computer (server) through network connection.
In the existing design, most of the E-INK display screens adopt wireless technologies such as Bluetooth or WIFI, a wireless module is arranged on each E-INK, or a communication network is formed by the E-INK display screens and an upper computer (server) in a wired connection mode. However, when a large number of E-INK display screens are required (e.g., price labels for supermarkets, numerous hospital rooms, and distributed areas are not in one area), the overall equipment cost may be increased if wireless equipment is provided on each E-INK or wired communication equipment is additionally provided on each E-INK.
Disclosure of Invention
In order to solve the technical problem in the background art, the utility model provides a E-INK network structure based on wireless mode of passing through can greatly reduced prior art in E-INK network equipment's investment cost.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a E-INK network structure based on wireless pass-through mode, E-INK include a plurality ofly, arrange respectively in a plurality of districts, every district all has a plurality of E-INK, a plurality of E-INK in every district passes through I2C bus interconnect, every district all has an E-INK to pass through the wireless pass-through module of RS485 bus connection 2.4G serial ports to through 2.4G wireless network connection server.
Each E-INK is provided with an I2C interface.
At least one E-INK of each zone is provided with an RS485 bus interface.
The server is also connected with a 2.4G serial port wireless receiving module and is connected with a 2.4G wireless network through the 2.4G serial port wireless receiving module.
Compared with the prior art, the beneficial effects of the utility model are that:
1) in the hardware design of the E-INK network structure of the utility model, the E-INK in each area is connected by the I2C bus, the I2C bus does not need to be additionally provided with a communication module, the main control MCU of the E-INK can be directly connected with the output I2C port through the port, and the network investment cost of each E-INK is greatly reduced;
2) in a plurality of E-INKs of each area, only one E-INK is provided with the RS485 communication module and matched with the wireless module, the E-INK provided with the RS485 bus interface is used as a master station of an I2C bus, a server sends display information of the area to the I2C master station through a 2.4G wireless network, then the I2C master station sends the display information of the area to other E-INKs, and other E-INKs do not need to be additionally provided with hardware communication equipment;
3) the 2.4G wireless module is connected with an external 2.4G wireless module in a RS485 serial port transparent transmission mode, the wireless transmission distance of the 2.4G wireless module is far longer than that of Bluetooth and WIFI under the condition that the 2.4G wireless module is not matched with other network equipment, the reliability is high, and the investment cost is lower than that of GPRS.
Drawings
Fig. 1 is a diagram of the network communication connection structure of the present invention;
FIG. 2 is a diagram of an embodiment of the design of the E-INK main control chip.
Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1, in an E-INK network structure based on a wireless transparent transmission mode, the E-INK is divided into a plurality of areas, and for example, an electronic price tag of a supermarket and an electronic tag of a consulting room of a hospital are taken as examples, a shelf of the supermarket or the consulting room of the hospital is divided into areas according to floors, so that the number of shelves of the supermarket is large, and each floor can also be divided into a plurality of areas.
Each area is provided with a plurality of electronic tags E-INK, and each E-INK is provided with an I2C interface. At least one E-INK of each zone is provided with an RS485 bus interface.
A plurality of E-INKs in each area are connected with each other through an I2C bus, and each area is provided with one E-INK which is connected with a 2.4G serial port wireless transparent transmission module through an RS485 bus and is connected with a server through a 2.4G wireless network. The server is also connected with a 2.4G serial port wireless receiving module and is connected with a 2.4G wireless network through the 2.4G serial port wireless receiving module.
