Swimming pool directional wireless signal trigger based on RFID technology

Abstract

The invention discloses a swimming pool directional radio signal trigger based on an RFID (Radio Frequency Identification) technology. The directional radio signal trigger comprises a unique transceiver ID, an LED (Light Emitting Diode) event indicator lamp and a miniature pinhole camera, wherein the transceiver ID contains address codes; the address codes are used for determining a fixed coordinate position of a swimmer in the swimming pool through logical computing, meanwhile, when the directional radio signal trigger is activated, the miniature pinhole camera mounted therein monitors and photographs images of a local site area of the directional radio signal trigger in real time. The swimming pool directional wireless signal trigger based on the RFID technology, provided by the invention, is applied in a drowning prevention safety guarantee system based on the RFID technology, can be used for monitoring water bottom state of the swimming pool in an event area through a shore-side monitoring system, and can learn real-time state image information.

Description

technical field [0001] The invention relates to the technical field of safety assurance, and more specifically, relates to a swimming pool directional wireless signal trigger based on RFID 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 example, the design of usin...

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 detected and dealt with effectively 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. Perform data collection and definition of individual swimmers

Moreover, the implementation of the image acquisition and comparison and calculation results is more complicated and must be realized by relying on real-time online operation with the network PC server and CCTV monitoring system;

[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 (signal angle, strength, time difference, etc.) In addition to affecting the appearance, when 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;

[0008] 5. The underwater state of the swimming pool in the event area cannot be monitored and obtained by the shore surveillance camera and the real-time state video information
