Description
Technical field
The utility model is related to the anti-drowned positioning bracelets of saving oneself of one kind, belong to brucker survival capsule field.
Background technology
Seashore tourism has become one of the first choice in tourism honeymoon, and bathing beach becomes a kind of fashion trend.And it thereby results in
Seawater be drowned problem be public concern.According to statistics, the number that China's seawater is drowned reaches 57000 person/year.Being drowned, it is complete to have become
Ball is only second to the second largest accident casualty origin cause of formation of road traffic accident.Currently, sea is drowned, prevention is rescued with emergency treatment with using
Raw clothing, She Li sightseeing towers, first-aid personnel is in real time based on rescue, and rescue means are single, inefficiency.Wearing life vest is chased after with tourist
Ask individual character to be reluctant that the original intention tied up is not inconsistent, and can skillfully grasp life vest application method and under emergency situation correct operation trip
Visitor is less.The sudden and unpredictability of another drowning incident, rescue team are difficult to make adequate preparation and are difficult to be accurately positioned
Drowning person position gives rescue personnel and prepares and arrange the time of rescue extremely limited.
Utility model content
The purpose of the utility model is to provide the anti-drowned positioning bracelets of saving oneself of one kind, and collection is portable, saves oneself, positions

Between bottle.
In a kind of anti-drowned positioning bracelet of saving oneself above-mentioned, the starter includes self-test starter, and the self-test is opened
Dynamic device is connected to first electromagnet and the second electromagnet, and pressure sensor is provided in self-test starter.Self-test is opened
It is equipped with pressure sensor in dynamic device, pressure sensor measures the rule of user's arterial pressure and is converted to heart rate, works as detection
To heart rate value increase suddenly, and when reaching given threshold (150 beats/min), self-test starter then makes the first electromagnet,
Two electromagnet power off certain time, wait for that the first electromagnet, the second electromagnet lose magnetism, cannot be by the first electromagnet and the second electricity
The partition that magnet is sucked is fast moved to gas cylinder, and point then quickly punctures gas cylinder, then the first electromagnet and the second electromagnet
Power resumption again, regains magnetism, partition is sucked again.
In a kind of anti-drowned positioning bracelet of saving oneself above-mentioned, the starter further includes manual starter, is manually booted
Device is connected to first electromagnet and the second electromagnet.User can be by pressing the first electricity of manual starter control
The power on/off of magnet and the second electromagnet, to make the point of switching device puncture gas cylinder.
In a kind of anti-drowned positioning bracelet of saving oneself above-mentioned, the device for opening includes partition and point, and point is solid
Due on partition.For point for puncturing closed gas cylinder, partition can obstruct gas, prevent gas from entering spring part and be located at
Cavity in, so that gas is directly entered in air bag by gas passage；Partition can also be inhaled by the first electromagnet and the second electromagnet
Firmly.
In a kind of anti-drowned positioning bracelet of saving oneself above-mentioned, the partition is metal spacer.Using metal spacer, be in order to
Partition (such as iron partition) can be sucked in first electromagnet, the second electromagnet in the energized state.
In a kind of anti-drowned positioning bracelet of saving oneself above-mentioned, the point is metal needle, and the metal needle is coniform.
In a kind of anti-drowned positioning bracelet of saving oneself above-mentioned, the gas storage device further includes waterproof cover, and described first
Electromagnet, the second electromagnet, spring part, gas cylinder and device for opening may be contained in waterproof cover.Waterproof cover can prevent water from immersing
In gas storage device, play the role of the various structure members in protective gas storage device.
It is high-pressure carbon dioxide gas in the gas cylinder in a kind of anti-drowned positioning bracelet of saving oneself above-mentioned.
In a kind of anti-drowned positioning bracelet of saving oneself above-mentioned, it is provided with reset switch in the self-test starter, described the
One electromagnet and the second electromagnet are connect with reset switch.It can make the first electromagnetism by the reset switch in self-test starter

The positioning function of type bracelet.Zigbee locating modules are sent an SOS by ad hoc network to neighbouring the utility model bracelet,
Distress signal is set to be easier to be found by people.GPS positioning module is used to be accurately positioned drowned personnel and stores the position for the personnel of drowning
Information.Wireless communication module is mainly fed back to information in bracelet monitoring system by GPRS, and lifesaving personnel monitor according to bracelet
The distress signal of system feedback, is rescued in time.
After the anti-drowned positioning bracelet of saving oneself of drowning person sends an SOS, wear with the anti-drowned positioning bracelet of saving oneself of money
User can have found drowning person in time according to the distance of anti-drowned save oneself alarm signal and detection that positioning bracelet is sent out, right
Drowning person sues and labours；Meanwhile rescue personnel can have found that anti-drowned positioning bracelet of saving oneself makes in time by bracelet monitoring system
Rescue work is implemented in the position of user in time convenient for rescue personnel.Bracelet monitoring system can monitor simultaneously in a certain range
It is multiple anti-drowned from lifesaving positioning bracelet.
It is the algorithm based on distance for the anti-drowned location algorithm in positioning bracelet of saving oneself, in the feelings of known transmission power
It under condition, is measured in receiving point and receives power, mobile node can be extrapolated to reference node by measuring the signal strength received
The distance of point.In position fixing process, need to utilize two key technologies of ZigBee：(1) mark of ZigBee node：Each
ZigBee node has 64 permanent address, as its unique identification.Permanent address can be mapped as having application layer
The name of meaning, so as to carry out identification to each node.(2) positioning judgement：The foundation of position judgment is wireless signal
Parameter LQI (Link Quality Indicator)：The precision of link signal quality, position judgment is distributed depending on routing node
Density.
There are mainly four types of methods for the process of positioning and calculating：
(1) grid location：ZigBee is positioned into reference mode, latticed to be equally spaced into, mobile node connects respectively
The LQI between reference mode is received, the distance of adjacent node is calculated with LQI, mobile node is calculated with trigonometric function method
Coordinate.
(2) some signal strength positioning：Mobile node is when different positions receives signal, because remote away from reference mode distance
Close difference, the signal strength received are also different.After mobile node receives the LQI values of nearest reference mode, pass through
It calculates or contrasts, determine the position of mobile node.
(3) two signal strength positioning：Mobile node receives two neighboring reference mode signal, calculates its difference, really
Determine transfer point position.
(4) fixed point location：The position that node of maximum LQI values will be received, when as positions of mobile nodes.This side
Method needs smaller network node spacing, precision relatively low.
Compared with prior art, the utility model bracelet such as integrates portable, saves oneself, positioning at the advantages, can prevent from making
User sinks under the water when drowned, and can send distress signals in time so that user is timely rescued；The utility model is anti-
Drowned positioning bracelet of saving oneself can establish information between other anti-drowned positioning bracelet of saving oneself in a certain range and be coupled, and connect
Receive sent out alarm signal and location information each other.Pass through the positioning system of the anti-drowned positioning bracelet of saving oneself of the utility model, rescue
Personnel can have found drowning person in time, and the position of drowning person is accurately positioned, and implement to rescue to drowning person in time.
