Embodiment Construction

[0008] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings. figure 1 It is a schematic diagram of a wireless digital photo frame 1 provided by the present invention, which includes a wireless network module 2 , a network processing unit 3 , a control unit 4 , a storage unit 5 , a display unit 6 , and a liquid crystal display 7 . Among them, the network processing unit 3, the control unit 4, the storage unit 5, and the display unit 6 are realized by FPGA. The wireless network module 2 completes the function of the wireless network interface and receives photo data sent from the computer 8 . The network processing unit 3 receives the data transmitted from the wireless module 2 and first judges whether it is the data of the UDP protocol, and then judges whether it is the photo data sent by the computer 8. After the above jud...

Abstract

The invention discloses a wireless digital photo frame based on an FPGA for implementation. The wireless digital photo frame can update photos through a WIFI wireless network. The wireless digital photo frame is composed of a display module comprising a liquid crystal displayer, a control module implemented through the FPGA and a wireless network module. A computer wirelessly transmits data to the wireless network module in a WIFI mode; a UDP protocol is used for wireless network transmission of the data; after the data are received, judgment of network data and full hardware decoding of UDP protocol data are completed through the FPGA; lastly, the data are displayed through the display module. Compared with an existing digital photo frame, the wireless digital photo frame has the advantages of wireless transmission, full hardware logic implementation, stable operation and a higher updating speed, thereby being capable of being applied to families, offices and other occasions for displaying digital photos.

Description

Technical field: [0001] The invention belongs to the field of data transmission and processing, in particular to a wireless network data processing structure and control logic design and realization based on FPGA (Field Programmable Gate Array), and is mainly applied to wireless transmission and display of digital photos. Background technique: [0002] In recent years, digital photo frames have gradually replaced traditional wooden photo frames and are used as a tool for people to view photos. Digital photo frames are generally connected to storage devices through USB interfaces or SD cards and other memory card interfaces, and store the data in the storage devices. The image files are displayed on the LCD monitor. [0003] If this digital photo frame needs to update the photos, it usually needs to unplug the attached memory card, plug it into the computer and copy it before updating, which is inconvenient to update and needs to take up a large-capacity memory card.
