Abstract: Provided are data acquisition equipment and a method and system for sharing data between the data acquisition equipment. The method includes: acquiring a gravity sensing value detected in real time by first data acquisition equipment in motion, wherein the first data acquisition equipment is anyone piece of data acquisition equipment in a data acquisition equipment group; when it is detected that the gravity sensing value meets a preset condition, reading data acquired by the first data acquisition equipment according to a predetermined sharing rule; and sending the data acquired by the first data acquisition equipment according to the sharing rule to any at least one piece of second data acquisition equipment in the data acquisition equipment group, wherein there is a pre-established data transmission channel between the second data acquisition equipment and the first data acquisition equipment.
