Control method of read-write indicating lamp and related device

The invention discloses a control method of a read-write indicating lamp, which comprises the following steps: when a read-write indicating signal generates level jump, outputting a square wave signalto the read-write indicating lamp according to a preset frequency; Determining a signal change period according to the jump period of the level jump; And when the duration of any level jump is greater than the signal change period, outputting a constant level signal to the read-write indicating lamp. By shortening the judgment waiting time of an original signal, redundant flickering is reduced, and wrong indication information is prevented from being transmitted. The invention further discloses a control device of the read-write indicator lamp, an indicator lamp controller and a computer readable storage medium which have the above beneficial effects. 本申请公开了一种读写指示灯的控制方法，包括：当读写指示信号发生电平跳变时，根据预设频率向读写指示灯输出方波信号；根据所述电平跳变的跳变周期确定信号变化周期；当任意一个电平跳变的持续时长大于所述信号变化周期时，向所述读写指示灯输出恒电平信号。通过缩短对原信号的判断等待时间，减少多余的闪烁，避免传递出错误的指示信息。本申请还公开了
