Embodiment Construction

[0053] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0054] refer to figure 1 , a force measuring method is provided in an embodiment of the present invention, comprising the steps of:

[0055] S1. Obtain the pressure value of the first gas in the airbag and the current temperature of the first gas when the measured pressure acts on the airbag.

[0056] In this step, the above-mentioned airbag is a flexible sealing capsule made of high-elastic rubber material, or a part is a flexible sealing capsule, such as the upper and lower sides of the capsule are parallel plates, the plate The peripheral side of the bar is sealed and connected by a flexible air-impermeable material. The above-mentioned airbag is generally provided with an air inlet and an air outlet. The air inlet is used to fill the airbag with gas. The air inlet is provided with a valve core. In another...

Abstract

The present invention discloses a force measurement method and device, and a force measurement device. The method comprises: obtaining first gas pressure value in an air bag when measured pressure is acted at the air bag and the current first gas temperature; calculating the gas pressure difference between the first gas pressure value and the initial gas pressure value in the air bag when the air bag is zero load; searching a force measurement correction parameter corresponding to the first gas temperature value in a temperature parameter list; and according to the gas pressure difference value, the force measurement correction parameter and the calibration proportion coefficient, calculating the pressure value of the air bag, wherein the calibration proportion coefficient is a coefficient through preset weight calibration after the pressure at the outer surface of the air bag is converted to internal gas pressure difference. The force measurement method and device, and the force measurement device employ gas pressure change of the air bag and the correction of the pressure value through adoption of the temperature to perform force measurement, the air bag is employed to make a force measurement device, the force measurement device is simple in usage condition and can be conveniently used on an intelligent wearable device, such as intelligent shoes and the like.

Description

technical field [0001] The invention relates to the field of force measurement, in particular to a force measurement method, device and force measuring instrument. Background technique [0002] At present, the use of human health monitoring equipment such as electronic scales and body fat meters is becoming more and more popular. The principle of general electronic scales is: when the object to be weighed is placed on a horizontal scale platform, its weight is transferred to the weighing scale through the scale body. The sensor, the sensor then produces a force-electric effect, which converts the weight of the object into an electrical signal (voltage or current, etc.) that has a certain functional relationship (generally proportional) to the weight of the object being weighed. This signal is amplified by the amplifying circuit, filtered and then converted into a digital signal by an analog / digital (A / D) converter, and the digital signal is then sent to the microprocessor (C...
