Structure and method of automatically sensing node position based on partial pressure in replaceable node body sensor network

Abstract

The invention provides a structure for automatically sensing a node position based on voltage division in a replaceable node body sensor network. The structure comprises intelligent modules, each of the intelligent modules comprises a casing which is provided with a Pogo female seat, clamping pieces are arranged at wearing positions, and each of the clamping pieces is provided with a Pogo male seat matched with the Pogo female seat. The structure is characterized in that a jack 1 of each of the Pogo female seats is connected to the GND, a jack 2 of each of the Pogo female seats is connected toone end of a resistor R1 and an input end of an ADC, the other end of the resistor R1 is connected to a VCC, the input end and output end of the ADC are connected to an MCU, a resistor R2 is connected between a pin 1 and a pin 2 of each of the Pogo male seats, and the intelligent modules and the clamping pieces are connected through the Pogo female seat and the Pogo male seat. During connection,the pin 1 is matched with the jack 1, the pin 2 is matched with the jack 2, the resistance values of the resistors R2 in the clamping pieces at the wearing positions are different, and the resistancevalues of the resistors R1 in the intelligent modules are the same. The invention also provides a corresponding automatic sensing method, and the problem that module wearing positions need to be manually designated is solved completely.

Description

technical field [0001] The invention belongs to the field of intelligent wearable technology, and in particular relates to a structure and method for automatically sensing node positions based on voltage division in a replaceable node body sensor network. Background technique [0002] In the human body motion capture system, a body sensor network is required, such as figure 1 shown. That is to attach smart modules containing motion sensors to various parts of the human body to achieve the purpose of tracking the movement data of various parts of the body. [0003] The wearing form of the body sensor network is generally: it is worn on the body in the form of sportswear or sports protective gear, and each intelligent module is embedded in the corresponding position of the sportswear or sports protective gear, such as figure 2 shown. [0004] The advantage of this method is that it is simple to wear, and the body parts corresponding to each node are fixed. But the disadva...

Problems solved by technology

But it brings a problem, that is, what part of the body each node is actually attached to, needs to be specified by the user when using it, which is a cumbersome process
