Embodiment

[0031] Joint bidirectional flexure measurement devices, such as figure 1 As shown, it includes a current-type bidirectional bending sensor, an elastic base 23, a driver, and a data acquisition processor. The current type bidirectional bending sensor is electrically connected with the driver, and the driver is connected with the data acquisition processor in communication.

[0032] The data acquisition processor includes information acquisition and exchange interface, data processing and visualization module. The data processing and visualization module is used to control the information collection and exchange interface, and obtain data for processing or display. In this embodiment, the data acquisition processor is a PC, but the use of embedded systems, mobile phones, tablet computers and other solutions to form the data acquisition processor is also within the protection scope of this patent.

[0033] The driver includes a sensor interface, an information publishing interf...

Abstract

The invention discloses a two-way joint bending measurement device in the technical field of measurement devices, and solves the problem that the two-way joint bending degree cannot be measured. The two-way joint bending measurement device is characterized by comprising an amperometric two-way bending sensor, an elastic base, a driver and a data collection processor, wherein the driver comprises asensor interface, an information distribution interface and an original data processing module; the data collection processor comprises an information collection interchange interface and a data processing and visualization module. The amperometric two-way bending sensor is fixedly installed on the elastic base, and the amperometric two-way bending sensor comprises a light emission assembly, a light receiving assembly and a light guide element. The luminous fluxes of the light guide element correspond to the two-way bending degrees of the light guide element one to one, according to output current, the two-way bending degree of a to-be-measured object is judged, and the function of automatically monitoring two-way bending of the joint of the object in real time on line at a large time interval can be achieved.

Description

technical field [0001] The invention relates to the technical field of measuring devices, in particular to a joint bidirectional bending measuring device. Background technique [0002] The bending of joints is usually attributed to a single degree of freedom measurement problem. Obviously, the bending of many joints in a certain degree of freedom is bidirectional. For example, the wrist can be raised and lowered, and even some finger joints of many people can be bent upwards. With the development of disciplines such as exercise physiology, zoology, and rehabilitation medicine, higher requirements are put forward for the measurement of joint bidirectional bending. The application scenarios of joint bidirectional bending are very extensive, such as biology, zoology, rehabilitation medicine, robotics, and aircraft, and other disciplines, and the application range of joint bidirectional bending includes but is not limited to the above-mentioned disciplines. At present, there is...
