Embodiment Construction

[0045] The present invention is further described below with reference to the accompanying drawings, taking the application of the pace measurement and transmission system based on pedestrian gait detection in automatic speed control of a walking robot as an example.

[0046] A walking robot is a mobile robot that assists the elderly and those with lower extremity diseases, which will provide support for the user during exercise. And its movement must be synchronized with the user to keep the gait to follow.

[0047] figure 2 This is a schematic diagram of the speed detection and transmission system of this embodiment. It consists of a speed detection part and an output part. The former calculates the speed and movement distance of the subject based on the acceleration information obtained from the subject. The obtained data will be transmitted to the upper computer of the walking robot through wireless communication, and the movement speed of the walking robot will be contr...

Abstract

The invention relates to system and method of walking speed measurement and transmission and aims at providing a pedestrian gait detection-based system and a method of walking speed measurement and transmission. The system comprises an acceleration detection unit comprising a double-spindle acceleration sensor and peripheral circuits, an acceleration processing unit, a gait analysis unit, a speed analysis unit, a wireless communication emission unit, a wireless communication receiving unit and an output terminal. The speed detection system has the advantages of lower cost, convenient use and installation, basically no limitations in use, and better real-time performance and external interfaces in comparison with the prior art. Gait characteristics can be extracted from acceleration data during human movement so as to detect the instantaneous speed, the average speed, the displacement distance, the movement time of and the step number.

Description

technical field [0001] The invention relates to a system and method for measuring and transmitting pace, in particular to a system for extracting gait features from acceleration data during human movement, and detecting instantaneous movement speed, average speed, moving distance, movement time and number of moving steps and method. Background technique [0002] Personal speed detection has important implications in real life. In terms of rollator control, the speed of the user can be measured by the speed detection device on the user's body, and the speed of the rollator can be controlled by the motor, so that people and vehicles can follow, without the need for people to control the moving speed of the rollator through external force. In terms of personal navigation, personal navigation and positioning can be easily realized by detecting personal speed and moving distance, and this solution is particularly important in places where GPS signals cannot be covered. In the m...
