Zigbee-based wireless led display control system

Abstract

The invention relates to a wireless light emitting diode (LED) display screen control system based on ZigBee, which comprises an upper computer and a lower computer, wherein the upper computer comprises a personnel computer (PC) for compiling and displaying programs, the lower computer comprises a wireless LED display screen control card based on the ZigBee, the wireless LED display screen control card is connected with an LED display module and comprises a central processing unit (CPU) (ARMLPC2214), a ZigBee RF transceiver (CC2520), a driving module, a memory expansion module and other basic circuits, and the upper computer and the lower computer realize the wireless data transmission. The wireless LED display screen has the advantages that the data is transmitted in a wireless way, the wiring cost is reduced, in addition, the difficulty of data transmission incapability in the wild or in special places inconvenient for wiring can be solved, the application range of the LED display screen is expanded, the LED display screen control card adopts a 32-bit embedded micro controller, the control card is used as full function equipment in a wireless communication network, and the self networking of the system can be conveniently realized.

Description

technical field [0001] The invention relates to an LED display screen control system, in particular to a ZigBee-based wireless LED display screen control system. Background technique [0002] Although the application range of LED display screens is becoming wider and wider, some problems have been exposed in the application. In terms of the transmission mode of LED display screen information, the existing wired data transmission can no longer meet the technical and economic requirements; Whether it is on the highway, or the large LED display on the airport, dock, building, and square, there are long cables or optical cables, which not only increase the cost, but also easily cause failures in communication; especially in the field or It is some special occasions that are not suitable for wiring that show the limitations of traditional technology. However, existing wireless transmission methods have difficulties in realizing information sharing between display screen systems....
