Embodiment Construction

[0040] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0041] The study found that deploying RFID readers on the edge of the swimming pool, and attaching RFID tags to the swimmer's head and arms, when the swimmer is swimming, the signal of the worn RFID tag will change periodically. Because swimming itself is a kind of periodic motion, the phase periodic change of the RFID signal thus caused has obvious correlation. Based on this finding, the present invention can determine the position of the swimmer by the trend of the RFID signal change; according to the RFID The periodic characteristics of signal changes identify the movements of swimmers, and then realize the goals of movement recognition and safety monitoring.

[0042] The RFID-based swimming safety monitoring system proposed by the present invention, such as figure 1 As shown, it mainly includes three modules: motion modeling module, motion evaluation modul...

Abstract

The invention provides an RFID-based swimming safety monitoring system. The system comprises an exercise modeling module, an exercise assessment module and a safety monitoring module, wherein the exercise modeling module is used for defining an activity in a single period as an exercise unit according to a periodical characteristic result of a swimming exercise, dividing the state of the swimmingactivity of an object into a non-swimming state and a swimming state, completing state division and transfer according to law analysis on received signals and establishing a personal stroke model by completing exercise unit division; the exercise assessment module is used for realizing stroke recognition and classification and stroke proficiency assessment on the object at least on the basis of the exercise modeling module; and the safety monitoring module is used for completing swimming activity monitoring and safety early-warning according to the received corresponding signals. Through the system, the demand for privacy in a swimming scene and the demand for low interference on the exercise of an RFID tag wearer are both considered, action recognition of the wearer is realized, and therefore the purpose of safety monitoring is achieved.

Description

technical field [0001] The invention belongs to the field of wireless sensing, and relates to the design, deployment and data analysis of a wireless sensing system based on RFID technology, which is used for motion capture and safety detection of monitoring swimming process. Background technique [0002] Swimming is a common way of fitness. It can improve the cardiovascular system, increase lung capacity, improve the function of the respiratory system, improve the ability of the muscular system, improve the mechanism of body temperature regulation, strengthen skin blood circulation, enhance resistance, and achieve Weight loss, bodybuilding goals. According to incomplete statistics, there are currently more than 10,000 swimming places in the country. At the same time, as a sport loved by all, the safety of swimming cannot be ignored. According to the Ministry of Health, it is estimated that 57,000 people die from drowning every year in the country, which is equivalent to mo...
