The invention discloses a redundant traffic countdown screen fault solving method comprising a fault detection input unit which is used for detecting the input state of fault detection equipment and monitoring the working state of a traffic countdown screen; the display unit is used for displaying data; the IO bus is used for controlling all digital display of the traffic countdown screen; the method has the advantages that the method for solving the traffic countdown screen fault in a redundant mode is adopted, when the traffic countdown screen breaks down, the display mode of the traffic countdown screen is changed, and the traffic countdown screen is displayed in a 9-second fixed-range mode. A countdown fault detection mechanism is used to find that a unit display unit of the traffic countdown screen is damaged; temporary faults of the traffic countdown screen are handled in a convenient mode, great significance is achieved for guaranteeing traffic safety, and great product marketization potential is achieved.
本发明公开了一种冗余式解决交通倒计时屏故障的方法,包括故障检测输入单元,所述故障检测输入单元用于实现检测故障检测设备的输入状态,监测交通倒计时屏的工作状态;显示单元,所述显示单元用于显示数据;IO总线,所述IO总线用于交通倒计时屏的所有数码显示控制;本发明的有益效果是:采用一种冗余式解决交通倒计时屏故障的方法,使得在交通倒计时屏在发生故障时,改变交通倒计时屏的显示方式,在交通倒计时屏采用9秒定程显示的使用场景下,通过倒计时故障检测机制发现交通倒计时屏的个位显示单元有损坏情况发生;通过便利的方式处理交通倒计时屏的临时故障,对保障交通安全具有极大的意义,具有较大的产品市场化潜力。
