Abstract

The invention provides a compartment space occupancy rate detection method, device and system and a storage medium. The method comprises the steps: controlling a sound wave generation module to transmit a transmitting signal of a preset time length to a compartment to be detected; calculating the duration of an echo signal received by a sound wave receiving module, wherein the echo signal is a sound wave signal reflected back by the transmitting signal after passing through the compartment; and determining the space occupancy rate of the compartment to be detected according to the preset timelength of the transmitting signal and the duration of the echo signal.

Description

technical field [0001] The present application relates to the technical field of detection and identification, and in particular, to a method, device, system and storage medium for detecting the space occupancy rate of a vehicle compartment. Background technique [0002] The existing space occupancy detection method of the carriage is to set a plurality of detection points at a certain distance from each other on the top of the carriage, and use the detection points to detect the remaining space height of the carriage directly below, and then according to the height information detected by each detection point And the interval between detection points to calculate the remaining space of the compartment. [0003] The above-mentioned method needs to install multiple detection points on the vehicle when detecting the space occupancy rate of the vehicle, which has the problem that it is not universal and inconvenient among different vehicles. Contents of the invention [0004...
