Embodiment 1

[0063] A kind of seat cushion for children's sitting posture detection provided by the present invention, the cushion comprises a cushion body, a measurement monitoring module L1, a plurality of pressure sensors L2 and a data transmission module L3 distributed in the cushion in an array form are arranged in the cushion; wherein (set in the cushion Please refer to the distribution structure diagram of some devices figure 1 ):

[0064] The plurality of pressure sensors are arranged as a pressure sensor array L2 with 36 rows and 36 columns, and are evenly arranged in the cushion to monitor the data of the pressure distribution of the human sitting posture; (for the distribution schematic diagram of the pressure sensors, please refer to figure 2 ); where each small square, for example, square "1" represents a pressure sensor array with 6 rows and 6 columns.

[0065] The measurement monitoring module L1 includes a control chip L11 and a sensor measurement circuit L12 connected in...

Embodiment 2

[0083] The invention discloses a device for interacting with a cushion, through which the data detected by the cushion can be further fed back to the user.

[0084] The device includes a data receiving and transmitting module A1, a main control chip A2 and a video and audio decoding module A3 (for the specific device structure diagram, please refer to Figure 5 );in:

[0085] The data receiving and transmitting module A1 is connected to the main control chip A2 for receiving the sitting posture data and further transmitting it to the main control chip A2;

[0086] The main control chip A2 is connected to the video and audio decoding module A3, which is used to turn on the timing mode when it is judged that what is received is bad sitting posture information after receiving the data, and when the duration of the detected bad sitting posture exceeds the preset time threshold Afterwards, control the video and audio decoding module A3 to send a vibration reminder, and / or make a v...

Embodiment 3

[0095] In this embodiment, the child's sitting posture detection cushion provided in Embodiment 1 and the device for interacting with the cushion provided in Embodiment 2 are further implemented to further realize the child's sitting posture detection, which specifically includes the following steps:

[0096] 1. The user starts to use the cushion, and detects the data of the pressure sensor array through the sensor measurement circuit in the cushion;

[0097] 2. The control chip provided in the seat cushion collects the data transmitted by the sensor measurement circuit; among them, for the received pressure array data, the control chip first collects the pressure distribution map data based on the data acquisition module;

[0098] Secondly, based on the sitting posture recognition module, under this module, the data in the sitting posture data sample database is used as the training sample, and the sitting posture recognition model is constructed through the convolution algori...

Abstract

The invention discloses a child sitting posture detection cushion, a device interacting with a cushion and a sitting posture monitoring method. The child sitting posture detection cushion is characterized in that pressure sensors are uniformly arranged in the cushion to monitor human body sitting posture pressure distribution data; for the processed pressure distribution diagram, modeling is performed on the pressure distribution diagram data by using a convolution algorithm, and sitting posture data of the user is obtained by using a modeling model; and after the device processes sitting posture data of a user and detects that the duration time of a bad sitting posture exceeds a preset time threshold, vibration is emitted and / or video and audio are / is made to remind the user. The child sitting posture detection cushion is used for detecting the sitting posture of the child in real time on the basis of the cushion and the device. According to the child sitting posture detection cushion, the convolution algorithm is used for processing the electronic data placed in the form of the image array to replace direct manual feature finding for the data detected by the sensor to establish amodel, and the convolution algorithm is directly used for directly performing intelligent modeling on the data without human intervention.

Description

technical field [0001] The invention relates to the field of intelligent interaction, more specifically, to a sitting posture monitoring cushion, a method for detecting sitting posture based on the cushion, and an interactive device for intelligently interacting with the cushion. Background technique [0002] With the progress of society, children's learning pressure is also increasing, and sitting for a long time has become a norm. Poor sitting posture has caused more and more children to experience varying degrees of vision loss, hunched back, spinal injuries, etc., seriously affecting children's physical and mental development. [0003] Common methods for detecting children’s sitting posture mainly include wearable, distance detection, infrared detection, and binocular camera; common sitting posture prompts or feedback methods include vibration, sound and light, light, and screen display. However, due to the inconvenience and easy loss of wearing, it is not suitable for ...
