LED显示屏异步控制系统又称LED显示屏脱机控制系统或脱机卡，支持3G和GPRS以及串口网口等通讯功能，该系统通过异步技术有效的解决了同步系统无法进行集群管理、无法进行远程控制的技术薄弱环节。解决了广告LED行业前几年的发展困惑问题。简易的LED显示屏异步控制系统只可以显示数字时钟、文字、特殊字符。而图文led显示屏异步控制系统则可以分区域控制显示屏幕内容，支持模拟时钟显示、倒计时、图片、表格及动画显示，并且具有定时开关机、温度控制、湿度控制等功能。系统具有操作简单、价格低廉、使用范围较为广泛的优点，广泛应用于户扭王块模具 高铁遮板模具 阶梯护坡模具 拱形护坡模具 卵形槽模具 保定室内设计培训 保定平面设计培训外广告，交通诱导，商超，银行，美容院，医院等领域！
LED display asynchronous control system, also known as LED display offline control system or offline card, supports 3G, GPRS, serial port network port and other communication functions. Through asynchronous technology, the system effectively solves the technical weak link that synchronous system cannot carry out cluster management and remote control. It solves the development puzzle of ad LED industry in the past few years. The simple LED display asynchronous control system can only display digital clock, text and special characters. The asynchronous control system of LED display screen can control the content of display screen in different areas, support the display of analog clock, countdown, pictures, tables and animation, and has the functions of timing on-off, temperature control, humidity control, etc. The system has the advantages of simple operation, low price and wide range of use. It is widely used in outdoor advertising, traffic guidance, supermarket, bank, beauty salon, hospital and other fields!
