随着经济社会的不断进步,LCD广告牌作为面向公众的信息显示终端之一,有着极其广泛的民用和商业价值。虽然市场中已经出现了各种类型的LCD广告牌,但大多数LCD广告牌信息显示采取的是预先将显示信息固化在系统之中,这失去了信息的时效性,特别不方便用户更新显示内容。少数LCD广告牌采用了与微机直接相连,用微机来传送信息,这种系统解决了信息刷新问题,但由于有线连接,制约了系统放置的随意性,特别是对于面向多地区多客户的广告公司来说,给系统的实时更新和维护带来了诸多不便。该文设计采用无线传输技术,实现了对广告牌内容及显示方式的灵活设置,具有很好的应用价值。

With the continuous economic and social development, LCD billboards, used as a public information display terminal, has a very wide range of civil and commercial value. Although there have been various types of LCD billboards in the market, most LCD Billboard information is stored in the system in advance, leaving the information out of date.
