The invention relates to the technical field of automatic driving, and discloses a multi-sensor synchronous triggering system and method. The multi-sensor synchronous triggering system at least comprises multiple sensors, a main control module and a signal generation unit, and the main control module is in communication connection with the signal generation unit and the multiple sensors; the signal generation unit generates a main trigger signal according to a preset trigger period and preset time, and sends the main trigger signal to the main control module; and the main control module performs abnormity monitoring on the main trigger signal to obtain a monitoring result, generates a redundant trigger signal according to a trigger period, and outputs the main trigger signal or the redundant trigger signal to the multi-path sensor according to the monitoring result to trigger the synchronous operation of the multi-path sensor. According to the invention, the stability of synchronous triggering of multiple sensors is improved, and high-precision synchronous triggering is also realized when the main control module is abnormal.
本发明涉及自动驾驶技术领域,公开了一种多传感器同步触发系统及方法。该多传感器同步触发系统至少包括多路传感器、主控制模块和信号发生单元,其中,主控制模块分别与信号发生单元和多路传感器通信连接;信号发生单元按照预设触发周期和预设时间生成主触发信号,并将主触发信号发送至主控制模块;主控制模块对主触发信号进行异常监测,得到监测结果,以及按照触发周期生成冗余触发信号,并根据监测结果,将主触发信号或者冗余触发信号输出至多路传感器,以触发多路传感器的同步操作。本发明提升了多路传感器同步触发的稳定性,在主控制模块发生异常时也实现高精度的同步触发。
