The invention relates to a vehicle-mounted control display system with dual-system safety redundancy display, which comprises a first control system, a second control system and a display screen, the first control system and the second control system mutually back up program data of each other, are mutually cascaded through a vehicle-mounted network and are used for mutually monitoring states of each other; the signal output ends of the first control system and the second control system are jointly connected with a signal synthesizer for synthesizing the two paths of display signals into one path of display signal; and the output end of the signal synthesizer is connected with the display screen and is used for outputting one path of display signal to the display screen and respectively displaying the contents of the first control system and the second control system. The two control systems are displayed on the same display screen at the same time, an independent touch control system is arranged, and when one control system cannot display due to failure of a control part, the other control system can start a corresponding program to replace the failure system to continue displaying.
本发明是一种带有双系统安全冗余显示的车载操控显示系统,包括第一控制系统、第二控制系统和显示屏,所述第一控制系统与第二控制系统互相备份对方程序数据,并通过车载网络相互级联,用以互相监测对方状态,所述第一控制系统和第二控制系统的信号输出端共同连接信号合成器,用于将两路显示信号合成一路显示信号;所述信号合成器的输出端连接显示屏,用于将一路显示信号输出到显示屏上,分别显示第一控制系统和第二控制系统的内容。本发明将两个控制系统同时显示在一个显示屏上,并且有独立的触摸控制系统,当一个控制系统由于控制部分的失效而无法显示时,另一个控制系统会启动相应的程序,代替失效系统继续显示。
