Data acquisition system based on wearable device

The invention relates to the field of wearable device data detection control, in particular to a wearable device-based data acquisition system, which obtains the acceleration and the acceleration direction of a wearable device through a detection module so as to judge the use state of the wearable device, the first use state represents a forbidden state, and the second use state represents a forbidden state. In the first use state, the stretching length of the back fixing strap is adaptively reduced to guarantee assistance, in the second use state, the running state is represented, the stretching length of the back fixing strap is adjusted based on the stress variation of each shoulder strap in unit time, the discomfort of running is reduced on the premise of guaranteeing assistance, and in the third use state, the bending posture is represented, and the comfort of running is improved. The telescopic length of the back fixing belt is increased based on the acceleration of the wearable device, then discomfort
