Anti-drowning system, anti-drowning method, anti-drowning swimming pool, and construction method and reconstruction method for swimming pool

Abstract

The invention provides an anti-drowning system, an anti-drowning method, an anti-drowning swimming pool, and a construction method and a reconstruction method for the swimming pool. The system comprises a plurality of first radio-frequency identification electronic tag devices, wearable second radio-frequency identification electronic tag devices and at least one radio signal acquisition device, wherein the first radio-frequency identification electronic tag devices have address codes for expressing the positions thereof in the swimming pool, and are arranged at the bottom of the swimming pool in the form of an array; each second radio-frequency identification electronic tag device has a unique identification number and at least comprises a water pressure detection sensor used for judging whether the corresponding swimming person is in a drowning state or not, the second radio-frequency identification electronic tag devices carry out radio-frequency identification with the first radio-frequency identification electronic tag devices at the bottom of the swimming pool respectively, and the address code of the first radio-frequency identification electronic tag device with the strongest radio-frequency signal is used as the address code of the position of the corresponding second radio-frequency identification electronic tag device in the swimming pool; and the radio signal acquisition device carries out radio communication with each second radio-frequency identification electronic tag device, and can send the address code of the position of each second radio-frequency identification electronic tag device in the swimming pool to a control terminal.

Description

technical field [0001] The present invention relates to the technical field of safety assurance, and more specifically, to an anti-drowning safety monitoring and assurance system based on RFID Internet of Things technology. Background technique [0002] Swimming is both a traditional and a popular sport that is practiced in various forms every year by both adults and children. In recent years, child drowning incidents in swimming pools have continued to occur. As far as Shanghai is concerned, there have been many child drowning incidents in some more formal swimming pools in recent years. This not only brings great grief to the family, but also poses a business risk to the business unit. How to ensure children's swimming safety and how to strengthen the protection mechanism of swimming pools is a common hot topic in society. [0003] The current overall solution and technology have the following core problems: [0004] 1. Not suitable for densely populated waters: For exam...

AI Technical Summary

Problems solved by technology

[0004] 1. Not suitable for densely populated waters: For example, the design of using underwater infrared detection and judging the static time of obstructions is not suitable for crowded waters, and is not suitable for synchronous and integrated intelligent supervision of a large number of people

[0005] 2. High false alarm rate: Due to the problem of the alarm algorithm, the false alarm rate of the SOS alarm signal is high, causing panic and disharmony on the scene, which invisibly increases the pressure and fatigue of lifeguards

Moreover, the physical reaction mechanism when an SOS event occurs is too primitive and monotonous, and cannot be effectively detected and dealt with in a timely manner.

[0006] 3. The alarm prompt is not clear and is subject to real-time networking with the network PC server: most of the current existing technologies use video surveillance or swimming stroke image comparison algorithms. Carry out data collection and definition of individual swimmers

Moreover, the implementation of image acquisition, comparison and calculation results is more complicated and must rely on real-time online operation with network PC servers and CCTV monitoring systems to achieve poor reliability.

[0007] 4. Inaccurate position judgment: Taking spatial three-dimensional recognition and positioning as an example, there are currently RFID three-dimensional multi-point detection and recognition technology algorithms. Although it can achieve rough position judgment, it is prone to position drift due to external factors. Unstable and unreliable, it is easy to mislead lifeguards to the wrong position and lose the best rescue time

Moreover, this method adopts three-point wireless detection and identification technology, which is immature and high in cost, and the most important thing is to install at least three or more card reader devices (three-dimensional signals such as signal angle, strength, and time difference) in the open. Three-dimensional algorithm), in addition to affecting the appearance, because the water surface and underwater environment and conditions are uncertain and messy, the position of the tag signal read by the card reader has large errors and mistakes
