Wearable passive body weight real-time detection device

Abstract

The invention discloses a wearable passive body weight real-time detection device. The device comprises a hollow detection shell (11). The device is characterized in that a bracket (6) is arranged atthe middle of the interior of the detection shell; a rocker (7) is arranged at the top of the bracket; the middle of the rocker is hinged to the bracket; the upper portion of one end of the rocker isfixedly connected with a central shaft rod (9); the central shaft rod passes through a tread hole (16) at the rear portion of the detection shell and is fixedly connected with a foot pressing sheet (10); the lower end of a connecting column is provided with a compression spring (8); the upper portion of the other end of the rocker is provided with a jacking and pressing column (2); a pressure sensor (1) is fixedly connected with the upper wall of the interior of the detection shell, and is located above the jacking and pressing column; the lower portion of the jacking and pressing column is fixedly connected with a magnet (3); the outer side of the magnet is provided with a coil (4); the coil is fixed at a corresponding position on the lower wall of the interior of the detection shell; a multi-function circuit board (13) is arranged in the detection shell; and the circuit board is provided with an electricity storage device, a wireless transmit-receive module, a signal amplification processing conversion circuit, and a control and storage circuit with an embedded program.

Description

Technical field [0001] The invention relates to a wearable weight tester, in particular to a wearable passive weight real-time detection device. Background technique [0002] As we all know, the value of individual body weight changes from birth to death. For a specific person, the change in weight value is obvious in some stages, and the change in some stages is not obvious, with weight gain and weight loss; for a group, some individuals have a large weight change rate, and some have a small weight change rate. Individual body weights are different at the same time. These weight values ​​and their changes and laws can reflect the health level of a person or the nutrition or disease status of the population in a certain area. Doctors often need to evaluate the patient's recovery through various data analysis. Therefore, it is very important to get real and effective weight data. Chinese patent 201610021858.5 discloses a built-in piezoresistive weight sensor for shoes, which c...

Problems solved by technology

Chinese patent 201610021858.5 discloses a built-in piezoresistive body weight sensor in shoes, which can realize daily monitoring of human body weight, but the piezoresistive body weight sensor does not solve the impact of the wet environment in the shoe on its normal work, nor does it specify the detection method How to use the data, there is no power supply device inside, it must be connected to an external power supply, which brings a lot of inconvenience to users
