The embodiment of the invention provides a combined inertial navigation system synchronization signal generation method and device, a medium and electronic equipment. The method comprises steps of carrying out analysis of a received positioning signal, and obtaining a second pulse signal and the standard time information; generating a synchronization signal corresponding to each sensor of the combined inertial navigation system by taking the second pulse signal as a reference; and outputting the synchronization signal and the standard time information to a corresponding sensor in the combinedinertial navigation system. The method is advantaged in that the synchronization signal required by each sensor in the combined inertial navigation system can be generated by taking the obtained pulsesignal as a reference, the high-precision synchronization signal can be continuously provided for the combined inertial navigation system under the condition that the synchronization signal cannot beobtained from the outside, and normal operation of the combined inertial navigation system is maintained.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method for generating a synchronous signal of an integrated inertial navigation system and a device for generating a synchronous signal of an integrated inertial navigation system. Background technique [0002] At present, unmanned driving equipment needs to use a variety of sensors for positioning, obstacle avoidance, map building, etc., such as using GPS sensors or GPS and inertial sensors combined inertial navigation equipment for positioning, orientation, single and binocular cameras, RGB cameras, etc. Vision equipment is used for positioning and mapping, and single-line and multi-line lidar are used for positioning and obstacle avoidance. [0003] In the prior art, when different sensor devices need to synchronize data on unmanned devices, software synchronization or hardware synchronization can only be achieved between two sensor devices, and it cannot be used for ...
