The dynamic frequency f of buckling1。
When the utility model is used, directly equipment is mounted on swimming cap by velcro in encapsulating shell and shell, then will swimming
Cap sleeve is on head, and in swimming, when occurring drowned, LED alarm lamp can issue alarm light in time while positioning being cooperated to mark
Label 3 are accurately positioned, and can find drowning person in time.
Compared with prior art, acquirement has the beneficial effect that the utility model:
11 multi-path resolved abilities are strong, and UWB has very high point due to its high working frequency and extremely low duty ratio
Resolution, the multipath signal of burst pulse are not easy to be overlapped in time, it is easy to multipath component are isolated, so transmitting can be made full use of
The energy of signal.Experiment shows the multi-path environment to conventional radio signal multipath fading as deep as 10~30dB, UWB signal
Decline is at most less than 5dB.
2, good concealment, because the frequency spectrum of UWB is very wide, energy density is very low, therefore information transmission safety is high.Separately
On the one hand, since energy density is low, UWB equipment for other equipment interference with regard to very low.
3, registration, impulse has very high positioning accuracy, using ultra-wide band wireless communication, can indoors and
Underground is accurately positioned, and precision reaches as high as 2 centimetres, and general precision is in 15 centimetres.And GPS positioning system can only operate in
Within the visual range of GPS positioning satellite.Different from the absolute geographical location of offer GPS, ultrashort pulse locator can provide phase
To position, positioning accuracy is up to Centimeter Level.
4, strong antijamming capability, UWB Spread spectrum processing gain depend primarily on the duty ratio of pulse and send each bit institute
Umber of pulse.The duty ratio of UWB is generally 0.01~0.001, has the processing gain more much higher than other spread spectrum systems, resists
Interference performance is strong.In general, the gain of UWB anti-interference process is in 50dB or more.
5, low-power consumption, UWB wireless communication system receiver do not have local oscillator, power amplifier, phaselocked loop (PLL), voltage controlled oscillator
(VCO), frequency mixer etc., thus structure is simple, equipment cost will be very low.Since UWB signal is not necessarily to carrier wave, but use interval
Pulse sends data, and the pulse duration is very short, generally between 0.20~1.5ns, there is very low duty factor, so it
Only need very low power.General UWB system only needs the power supply of 50~70mW, is 1/10th of Bluetooth technology.
7, it summarizes, main structure is simple, and design concept is ingenious, safe and convenient to use, by UWB and the ingenious combination of swimming cap,
Wearing using effect is good, and early warning is timely, is capable of the safety of effective protection user.Application environment is friendly, wide market.
