通过串口下载数据至LED显示屏控制卡的方法,传输速度慢,传输距离短。而利用网络技术,通过局域网通信的方法,使用Socket通信,可以避免通过串口下载的这些不足之处。同时,对于串联路由器的网络结构对局域网通信的限制问题,切合LED控制卡的实际,给出了详细可行的解决方案,能够保证在任何局域网环境下都能够实现LED控制卡的数据下载。
Through the serial port to download data to the LED display control card method, the transmission speed is slow, the transmission distance is short. The use of network technology, through the LAN communication method, the use of Socket communication, to avoid these shortcomings downloaded through the serial port. At the same time, the limitation of the network structure of the serial router to the LAN communication meets the actuality of the LED control card and gives a detailed and feasible solution, which can ensure the data download of the LED control card in any LAN environment.
