Embodiment 1

[0107] In this example, the tester wraps the two-handed ring sensor 100 on the wrist, and the collected data is transmitted to the host computer MATLAB software, and the environment for installing the MATLAB software on the host computer is to calculate various parameters. The tester collects data multiple times within a unit time, and performs real-time three-dimensional sensor data modeling on the data, and displays the data after matching and fusing the parameters of the two-hand ring. Such as image 3 As shown, the posture diagram of the two-hand ring gesture; Figure 4 Corresponding image 3 Two-handed clasp gesture, a three-dimensional sensor data modeling model diagram established with MATLAB software. Figure 6 This design, which incorporates a Kalman filter, can easily determine the angle of rotation of the hand by smoothing the input signals obtained from a three-axis accelerometer and gyroscope. Figure 5 The corresponding gestures are shown at the bottom of the . ...

Embodiment 2

[0110] The transmission module 5 (eg, GPS module) in the wristband sensor 100 can collect latitude and longitude information, and obtain position information through latitude and longitude correction processing. The location information can be used as the judgment condition of the machine learning of the server. With the Baidu map SDK embedded in the cloud server 200, the cloud server 200 can analyze the location information in the message CJSON, and analyze the location of the special care personnel. In order to prevent the elderly from getting lost, guardians can preset electronic fences to monitor the scope of activities of the elderly, and remotely understand the current activity area of ​​special caregivers, so as to know well, and do not need to pay attention to the location information of the elderly at all times. Once the elderly are found to exceed the preset activity range , the system raises an alarm and pushes a warning message to the mobile phone number bound to t...

Abstract

The invention discloses an intelligent remote special nursing monitoring system and method based on a double-bracelet sensor. The system comprises the two wearable bracelet sensors and a cloud server, and the bracelet sensors communicate with the cloud server. Each bracelet sensor comprises a positioning module, a sensor module, a control module, a storage module and a transmission module, wherein the positioning module, the sensor module, the control module, the storage module and the transmission module are connected in sequence, the positioning module is used for detecting the position of a user, the sensor module is used for detecting environment and movement sensor information, the control module is used for generating judgment data, the storage module is used for storing the data, and the transmission module is connected with the cloud server and transmits the data to the cloud server through an LEDP protocol. The user can achieve monitoring of a guardian through a computer terminal and a mobile phone APP. The intelligent remote special nursing monitoring system is good in universality and accurate in posture identification, the postures of the person under guardianship is observed in real time, the cost is low, and the system is convenient to carry.

Description

technical field [0001] The invention relates to the technical field of sensor information processing and gesture recognition, in particular to a system and method for remote intensive care monitoring based on two-handed ring sensors that integrate three-dimensional sensor data modeling and human-computer interaction. Background technique [0002] With the continuous development of science and technology, the continuous improvement of control and sensor technology, more and more devices use sensors to collect and observe human behavior characteristics. [0003] Smart bracelets currently on the market, because of their wearable, small size, multi-sensor, Bluetooth 4.0 wireless transmission and other characteristics, make smart devices enter people's lives. Through the combination of wristband and smart phone to measure heartbeat, count steps and record human sleep data and other information. The wristbands on the market are all in the form of a single-handed bracelet. For dev...
