Abstract: The present utility model provides a modularized induction flushing device for a urinal and an induction urinal. The modularized induction flushing device comprises a water inlet and outlet assembly, a water drainage assembly, an electromagnetic valve assembly, and a power supply assembly, wherein the modularized induction flushing device further comprises an induction module, the induction module is associated with the electromagnetic valve assembly and is attached to the water inlet and outlet assembly and/or the water drainage assembly, wherein the induction module is configured to be switched between at least two induction modes in a replaceable mode, and the electromagnetic valve assembly responds to different induction modes of the induction module to control flushing of the urinal.

Abstract: The present disclosure relates to a fast numerical simulation method for laser radar ranging considering a speed factor. According to the method, the motion of the laser radar itself and the motion of an object in the surrounding environment are fully considered in the simulation process. The motion of the laser radar itself not only includes the overall motion of the device, but also includes the rotary scanning motion of a laser emitter, so that accurate numerical simulation is provided. In addition, the amount of calculation is simplified by introducing a sampling point set, and the effect of improving the accuracy of simulation by using a small amount of calculation is achieved. The method is especially suitable for a scenario where the laser radar itself and/or surrounding objects are in a high-speed motion state, and can achieve a significantly higher simulation precision than that achieved by existing methods.
