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
And this method adopts three-point wireless detection and identification technology, its technology is still immature and cost remains high, and the most important thing is to need to install at least three above card reader devices (signal angle, strength, time difference) and other 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 interpreted by the card reader has large errors and mistakes

no. 1 approach

[0055] like figure 1 As shown, in the RFID-based underwater safety guarantee system of the present invention, a plurality of directional wireless signal transceivers 2 are installed at the bottom of the swimming pool for communicating with RFID electronic tags. Each directional wireless signal transceiver 2 has a unique transceiver ID, and the transceiver ID contains an address code. Based on the address code, the accurate current position of the swimmer in the swimming pool can be known through logical calculation, which can also be considered as a fixed coordinate position. The directional wireless signal transceiver 2 is installed and laid on the bottom of the swimming pool by an embedded or plastic-wood floor method. The directional wireless signal transceiver 2 is preferably directional, because the directional wireless signal transceiver 2 is installed at the bottom of the swimming pool, so its sending and receiving signal direction is along a fan-shaped signal radiation...

no. 2 approach

[0098] Multiple RFID tags are embedded inside. When a swimmer wears a transceiver, the transceiver will receive signals from multiple RFID tags. According to the ID of the RFID tag, the most accurate position of the swimmer can be determined. Its working principle is: multiple directional RFID electronic tags are installed at the bottom of the swimming pool, and the electronic tags have a unique position ID code. When the transceiver receives the RFID electronic tag position ID, it will be together with the unique ID physical code and event ID code Send to the omnidirectional wireless signal transceiver on the shore. When the transceiver does not receive and recognize the ID position code of the RFID electronic tag at the bottom of the pool, it only sends its own unique ID physical code to the omnidirectional wireless signal transceiver, so as to provide the system with basic information about personnel in the field. When the omnidirectional wireless signal transceiver receive...

Abstract

A kind of anti-drowning safety guarantee system based on RFID technology, comprising: the RFID electronic tag worn on the swimmer, the RFID electronic tag has a unique electronic tag ID; a plurality of directional wireless signal transceivers installed on the bottom of the swimming pool, directional wireless The signal transceiver can receive the event ID generated by the RFID electronic tag. Each directional wireless signal transceiver has a unique transceiver ID, and the transceiver ID contains an address code; the servo pan / tilt LED beam guide light can project lights with different effects On the water surface of the swimming pool; intelligent terminal central controller, which is used to receive the event ID, physical code ID and transceiver ID from the wireless signal transceiver, and control the LED beam guide light of the servo pan / tilt according to the event ID Turn on and off; among them, when turning on the LED beam guide light of the servo pan / tilt, the central controller of the intelligent terminal sends the event ID and the transceiver ID to the LED beam guide light of the servo pan / tilt, and the LED beam guide light of the servo pan / tilt is controlled according to the event ID Lighting effects and control the projection position according to the address code in the transceiver ID.

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...
