Liquid crystal screen interference self-recovery method applied to acquisition terminal

The invention discloses a liquid crystal screen interference self-recovery method applied to an acquisition terminal, and the technical scheme comprises an avoidance mechanism method and a self-recovery mechanism method which are respectively used for coping with two conditions that a liquid crystal screen is interfered to display wrong data and a liquid crystal screen control chip is crashed due to strong interference. According to the invention, the liquid crystal screen of the acquisition terminal can be prevented from being influenced by interference signals fundamentally; the pulse test death rate of the acquisition terminal group is reduced; the service life of the liquid crystal screen of the field acquisition terminal is effectively prolonged; the method has strong compatibility and is suitable for various acquisition terminals. 本发明公开了一种应用于采集终端的液晶屏干扰自恢复方法，其技术方案包括规避机制和自恢复机制两种方法，分别应对液晶屏受到干扰显示错误数据和液晶屏控制芯片受到强干扰死机两种情况。本发明可实现根源上避免采集终端液晶屏受到干扰信号的影响；降低了采集终端群脉冲测试死机率；有效的延长了现场采集终端液晶屏的使用寿命；兼容性强，适用于各种采集终端。
