Abstract

The invention relates to a design method of a portable double-sensing filtering high-precision measuring device for muscle strength. Firstly, an adapter fixing frame, a height adjusting support, a support base and a portable transport case are designed to form a combined support system, the weight of a tester and the weight of a chassis are used to resist bottom backward tilting moment possibly caused by force exertion of the tester, an Anhui Bengbu DYLY017 tension and pressure sensor and an LASCAUX Lijing STC tension sensor are installed to measure the muscle strength of the neck or other positions of the tester, an STM32 single-chip microcomputer with an AD collection channel collects muscle strength data, the muscle strength data is transmitted to a PC end through Bluetooth, a nonlinearlow-pass device is designed to firstly filter the data, and then an error compensation correction type Kalman filter is constructed to carry out error correction and Kalman filtering on the measurement data of the double sensors, so that data fusion is realized, and the measurement precision and reliability are improved. The method solves the problem that an existing muscle measuring device is complex to install and use and cannot achieve field measurement, and the measuring precision is improved.

Description

technical field [0001] The invention relates to the field of sports medical instrument design, in particular to a method for designing a portable muscle strength high-precision measuring device. Background technique [0002] Accurate measurement of muscle strength is of vital importance to improving the training level of athletes and aircraft pilots. The data of related muscle strength measurements can also provide data support for the recovery of physical functions of patients during rehabilitation. At the same time, muscle measurement data can also provide support for It provides an important basis for the selection of relevant athletes and aircraft pilots. The current commercially available cervical muscle strength or muscle strength measurement devices are bulky, and generally after a successful installation, they can only be placed in a special testing institution, and personnel are organized to come to the site for testing, which makes it inconvenient to use on many oc...
