Research Of Led Display Monitor Based On Zigbee Module Wireless Communication Technology

The LED electron display monitor is the collection microelectronic technology, the computer technology, the information processing and management technology in a body’s large-scale display monitor system. It is bright, brightness is high, the life is long, the work stable reliable and so on merits become the numerous demonstration media as well as the outdoor work demonstration ideal choice. In domains and so on bank, postal service telecommunication, hospital, sports complexes, negotiable securities, airport, school, road traffic, market shopping obtained the widespread application. Along with the21st century society informationization’s advancement, the LED display monitor’s application prospect is broad. Emerges from the late80s until now, the correlation technique and industry have made the considerable progress, becomes important present information issue media method, is also one of the21st century’s mainstream products. The traditional wired LED display monitor is away from and factor and so on space limits, has fettered screen’s application. This article designs based on ZigBee the technical wireless LED display monitor through the PC machine control Chinese character demonstration, may realize the short distance wireless control, is not away from the spatial limit, causes the LED display terminal both to be advantageous installs and changes places, and reduced the operating cost; At the same time, the modulation may assemble the LED display monitor, caused the screen size dimension to be possible to assemble according to the actual need, enhanced its usability, was the LED display monitor’s further application has created the condition.This article narrated in detail based on ZigBee the module wireless communication technology LED electron display monitor’s research design process. First elaborated that based on the wireless transmission’s LED lattice screen display system’s overall project design, divides according to the function the system into the superior machine transmission administration module, the wireless receiving and dispatching module and the LED lattice display module three parts, then narrates each module hardware circuit design and the software design in detail. The hardware circuit studied in the LED display module to demonstrate driving circuit’s design with emphasis; The software aspect,has carried on the superior machine transmission administration module serial port transmission and Chinese character character conversion lattice, CC2430programmings with emphasis and so on wireless receiving and dispatching. Finally, carries on the programming using Keil uVision2and the VC++6.0, the Proteus7.0software carries on the circuit diagram the design with to realize, and carries on two software jointing shake down testing conformity to the hardware simulation experiment system, realizes system’s basic function.
