具有模组识别及数据存储功能的智能模组控制系统

Smart Module Control System

逐点校正技术在LED行业已经被广泛应用,使得LED显示屏的均匀性得到很大的提升。但是,由于在通常LED系统中,体现模组特性的逐点校正数据是保存在接收卡中的。由于数据载体与其所体现对象的不一致,导致了在模组更换后,校正数据不能体现其实际相关的模组,造成更换位置的均匀性变差。这种因素的存在制约了逐点校正技术的使用。为从根本上解决这一问题,我们提出了智能模组的解决方案。此方案将校正数据存储在模组上,当软件检测到模组被更换后,自动将此模组的校正数据读出、并传输到接收卡,从而实现校正数据的自动更新。同时,此系统在模组间只需增加一根信号线进行通讯(即:单线传输),具备高可靠性。最后、此系统可具备低成本的模组故障辅助检测、电源检测功能,具备较高的实用价值。

The widespread application of the pixel-by-pixel correction greatly improves the uniformity of LED display. However, the correction data is stored in the receiving card in the conventional LED display control system. Therefore, after the module is replaced, the correction data can’t represent its actually related module and it leads to the worse uniformity of the position where the module is replaced because of the inconformity of data carrier and the object it embodies. The existence of these factors restricts the use of pixel-by-pixel correction technology.In order to solve the problem fundamentally, we come up with the solution of smart module. In this way, the correction data can be stored in the module. When the software detects that the module is replaced, the correction data of the module can be read out and transferred to the receiving card, thus realizing auto update of the correction data. Meanwhile, the system adopts single-wire transmission between modules, which is of high reliability. Last but not least, the system has functions of module fault detection and power detection at a low cost, which is of high practical value.
