The left side of body of person.
Based on the above technical solution, as shown in fig. 7, the vital sign collector 201 includes following at least one
Kind:
Acquire the pyroelectric infrared detector 2011 of body temperature.
Pyroelectric infrared sensor 2011 includes Fresnel Lenses, rpyroelectric infrared detecting head and amplifying circuit, comparator
And power supply.Its connection relationship is as shown in Figure 8.
Since pyroelectric infrared sensor 2011 is only just sensitive to continuous fast-changing infrared signal, and in nature
Infrared signal is typically all slowly varying or constant, it is therefore desirable to which probe segment, which needs one, to carry out infra-red radiation
The device of modulation, this needs use Fresnel Lenses before rpyroelectric infrared detecting head.Rpyroelectric infrared detecting head mainly by
Sensing element, high level load resistance and field-effect tube composition.The material of pyroelectric crystal used in sensing element is zirconium titanium
Lead plumbate system pyroelectric ceramics (PZT).
The piezoelectric transducer 2012 of acquisition breathing and heartbeat.
In breathing, with wall of the chest muscle relaxation, thorax replaces deformation, and the electrical impedance of body tissue will also generate alternate
Variation.Test proves that respiratory impedance value is directly proportional to Pulmonary volume.Therefore, breathing spray rate can be calculated by impedance method.Cause
This, can incude the alternating deformation of thorax by piezoelectric transducer 2012.
Since the amplitude of respiratory impedance signal with motion disturbance signals trend varying with frequency is different, with the increasing of frequency
Add, the amplitude of variation of impedance signal relevant to breathing increases, on the contrary, the amplitude of the interference signal caused by moving can but drop
It is low.Therefore, motion artifacts can be eliminated using the method that dual frequency impedancepneumography and adaptive processing technique combine.
The measurement of heart rate uses piezoelectric transducer.The contraction and diastole of human body ventricular cycle can generate the period in thorax abdomen
The deformation of property.This cyclic deformation of thorax abdomen, measures heart rate with this when pressure sensor experiences heartbeat.
The piezoelectric transducer 2012 can be fixed on belt type sensing zone, and belt type sensing zone is then bundled in lifeguard
Member's thorax abdomen, so that piezoelectric transducer 2012 is tightly attached to human body navel, 2012 induction pressure of piezoelectric transducer becomes when human body respiration
Change.
Acquire the acceleration transducer 2013 of user's posture.
The measurement of human body attitude is realized in the measurement of user's posture based on three axial acceleration transducers.Establish right angle seat
Mark system, X, Y, Z axis is mutually orthogonal, and the vector variation on any direction in space can resolve into point on tri- directions X, Y, Z
Amount variation；During tumble, acceleration transducer incudes the acceleration of object, speed and the equal variation mapping of three kinds of vectors of displacement
To rectangular coordinate system, user is under static or horizontal uniform speed motion state, and the acceleration of Z-direction is acceleration of gravity, anxious
Acceleration is all 0 in other both directions.When wearer falls, ideally z-component, which occurs to change from maximum value, is
0, and X or the component of Y-axis are then maximum from 0 variation, this variation occurs for specifically X-axis or Y-axis, then after being fallen by wearer
Posture determine lie down be X-axis change, lie on one's side for Y-axis variation.If body posture is between lying down and lying on one's side, then X-axis and Y
The component of acceleration of axis will meet preset condition, still be able to obtain the acceleration profile different from standing by calculating analysis.
But in a practical situation, it is difficult to differentiate the Crack cause for posture of droping to the ground according only to the change of component of acceleration, gently
Easily there are many false positives (detect and fall and reality is not fallen) or false negative (is not detected tumble and actually falls
).In general, false positive situation can speed, integral be asked twice by being asked in the primary integral of time-domain progress acceleration
The mode of displacement, comprehensive analysis wearer's body attitudes vibration are screened；And false negative situation is removed using above comprehensive
Outside posture analysis, it is also necessary to which wearer independently participates in the detector efficiency that could effectively improve.
Further, which further includes the power switch, buckle and bayonet for opening or closing wearable device,
On wearing accessory 204, bayonet is arranged on shell 203 for buckle setting；When bayonet and buckle mutually clamping, shell 203
It is fixed on wearing accessory 204.Bayonet is internally provided with the trigger for triggering power switch short circuit, when buckle and bayonet card
After connecing, buckle squeezes or contact trigger, so that the trigger is triggered.
Exemplary, trigger is the shorting switch for being shorted power switch.Optionally, when buckle and trigger not in contact with
Or when squeezing, shorting switch is opened, and power switch, which can be realized, opens or closes wearable device；When buckle contacted with trigger or
When extruding, shorting switch is closed, and power switch is shorted；Optionally, when buckle and trigger not in contact with or squeeze when, short circuit is opened
It closes, power switch, which can be realized, opens or closes wearable device；When buckle is contacted or is squeezed with trigger, shorting switch
It opens, power switch is shorted.
It is exemplary, it is assumed that trigger is level generator, and wearable device further includes controller, when controller detects triggering
When device is triggered, power switch failure is controlled, i.e. power switch is shorted.Optionally, when buckle and trigger not in contact with or not
When extruding, level generator output is low level；When buckle is contacted or squeezed with trigger, level generator output is
High level；When controller detects the high level of level generator output, control power switch is shorted.Optionally, when buckle with
Trigger not in contact with or when not squeezing, level generator output is high level；When buckle is contacted or is squeezed with trigger, electricity
Flat generator output is low level；When controller detects the low level of level generator output, control power switch is shorted.
In this way, trigger can prevent rescue personnel, trigger is triggered so that malfunctioning switch at work, in this way, preventing
Because of situations such as the occurrence of maloperation, body squeeze, equipment collision leads to wearable device error cut-off machine.
Exemplary, wearable device further includes work light；When the not connected individual soldier's communication terminal of booting, work light
For red, after connecting individual soldier's communication terminal, work light is green.
Embodiment three
Fig. 9 is a kind of structural schematic diagram for coal mine emergency rescue system that the embodiment of the present invention three provides, and the present embodiment can
The case where suitable for underground work or rescue, as shown in figure 9, the coal mine emergency rescue system includes:
Emergency command dispatching platform 30；Interchanger 40；Multihop routing 50；Individual soldier's communication terminal 60；
Any environment detection equipment 10 of embodiment one, and or any wearable device 20 of embodiment two.
Wherein, emergency command dispatching platform 30 by interchanger 40 and multi-hop road 50 by respectively with individual soldier's communication terminal 60,
Environment detection equipment 10 and or wearable device 20 connect；Environment detection equipment 10 and wearable device 20 are communicated with individual soldier eventually respectively
60 connection of end.Above-mentioned connection is all to be able to achieve the electrical connection of communication.
In the present embodiment, since each user requires to wear wearable device 20, individual soldier's communication terminal 60, therefore two are carried
Person needs to correspond, and can pass through bluetooth connection.Individual soldier's communication terminal 60 can also pass through bluetooth with environment detection equipment 10
Connection；5.8G frequency can be passed through between emergency command dispatching platform 30, interchanger 40, environment detection equipment 10 and multihop routing 50
The WiFi connection of section, individual soldier's communication equipment 60, environment detection equipment 10 pass through 2.4G frequency range between multihop routing 50 respectively
WiFi connection.
Wherein, network used in WiFi connection can be multihop network, with rapid deployment and be easily installed, non-view
Away from transmission, the features such as self-healing ability is strong, networking flexibility, strong scalability, it is fragile to be suitable for Mine Communication bad environments, network
Bad working environment.
Using the wireless multi-hop characteristic of multihop network, make all terminals of emergency rescue system can be wirelessly
It networks, extends the coverage area of wireless network；Using the self-organizing of multihop network, self-healing ability, when system node is installed to
It behind designated position, can automatically configure in network, after some nodes break down, using self-healing ability, network can be rapid
Resume work state.
Multihop network is the full Wireless network based on multi-hop communication, according to its distribution node, mainly by multi-hop gateway, more
Hop router and multi-hop terminal composition.Underground coal mine multihop network is different from ground multihop network reticular structure, needs to combine coal
The topological structure of mine underworkings is designed.In fully mechanized workface, with the operation of development machine, point tunnel is constantly to being pushed forward
Into, be suitable for setting up linear chain topology, and for air return lane, air inlet, fully-mechanized mining working fully mechanized mining area for, fit
In setting up annular chain topology, it is identical for setting up principle.
The optical cable in main tunnel is connected by router with the coal mine local area network on ground, and multihop network connection is connected on optical cable,
It is responsible for the forwarding of data between cable network and multihop network.Multiple router hops are interconnected by wireless multi-hop communication, are constituted wireless
Backbone network, there are two types of network interface card, a kind of support IEEE802.11g agreement, another kinds to support IEEE802.11a association for multiple router hops tool
View.In this multihop network, the wireless transmission in mining area is may be implemented in multi-hop terminal.
And in underground coal mine, due to tunnel environment complexity, the decaying of electromagnetic wave is different from ground environment, coarse with wall
The factors such as degree, wall gradient, tunnel dust, tunnel humidity are related, while the electromagnetic wave attenuation in tunnel near region and far field is bright
Aobvious difference.
In ground environment, the decaying of wireless signal is mainly the attenuation model as caused by path loss are as follows:
Wherein, P (ds) indicate away from transmitting node dsReceived signal power at rice；d0Indicate away from 1 meter of transmitting node away from
From；P0It indicates in d0Locate received signal power；R is fading factor, related with the complexity of environment.
At near region, electromagnetic wave attenuation can be indicated with the electromagnetic wave attenuation model of free space:
Lp(dB)=92.4+20lg (d)+20lg (f)；
Wherein, d indicates distance, and unit is km；F indicates frequency, and unit is GHz.
At far field, electromagnetic wave attenuation is influenced very greatly by tunnel environmental parameter, mainly coarse by wall in conjunction with experience
Degree, wall gradient and electromagnetic wave main mould influence of fading approximate can be indicated to drag:
Wherein, LIt is coarseIndicate loss, L caused by wall roughnessInclinationIndicate loss caused by wall gradient,
LMain mould decayingIndicate that electromagnetic wave main mould attenuation loss, h indicate r.m.s. roughness, z indicates transmission range, and λ indicates electromagnetic wavelength, W
Indicate that tunnel maximum width, H indicate tunnel maximum height, Δ indicates inclination angle, and d indicates tunnel length, εrIndicate wall phase
To dielectric constant.
In the design for carrying out underground coal mine wireless Mesh netword, electromagnetic wave attenuation reason should be carried out in conjunction with tunnel specific environment
By analysis.Meanwhile the design of node spacing is rationally carried out, because the signal that the increase of node spacing can reduce cochannel node is dry
It disturbs, but spacing is excessive also to reduce reception power.
Since multihop network has the characteristics that dynamic self-organization, self, wanted in carrying out the design of multihop routing criterion
Comprehensively consider the stability of routing, guarantee minimal weight path performance, calculating of the efficient algorithm to minimal weight path guarantees nothing
Key issues of routing of loop.Existing Routing Protocol mainly selects to route with hop count, is not able to satisfy underground coal mine chain
The requirement of multihop network.Switch (Metric of Interference and Channel in conjunction with interference metric and channel
Switching, MIC) criterion, the multihop network of underground coal mine is studied.
The criterion MIC of the multihop routing are as follows:
IRU1=ETT1N1；
If CH (prev (i)) ≠ CH (i), CSCi=w1；
If CH (prev (i))=CH (i) .CSCi=w2；
Wherein, p indicates path, and N indicates nodes number, and ETT is desired transmission time, and S, B respectively indicate data
The size of packet and the link bandwidth of transmission data.Wherein, N1Indicate interfering nodes when data transmission on link 1, prev (i) table
Show that the node of the i-node previous dive on the p of path, CH (i) are expressed as the channel of node i distribution, w1 < w2 indicates to be greater than 0 weight.
IRU in formula (9)1The interference of adjacent node, the interference in CSC representative of data flow are represented, CSC is selected according to formula (11).
Meanwhile MIC judgement does not have isotonicity.In underground coal mine design, by introducing the dummy node of node, by MIC
The link weight for being decomposed into order-preserving is assigned to method on virtual link, solves the problems, such as that MIC criterion does not have isotonicity.
Due to the particularity of underground coal mine, the multi-hop node of underground is generally in stationary state, network topology structure variation
Smaller, tunnel is long and narrow, and the number of nodes needed is more, and the handling capacity of network can be dropped with the increase of chain-shaped network hop count
It is low.For Reactive routing protocols to network resource utilization height, handling capacity is big, but data transmission has delay between equipment；Priori formula
The efficiency of transmission of Routing Protocol is high, can be reduced using tabledriven algorithm and is delayed end to end.As it can be seen that single multihop routing agreement
It is unable to satisfy the demand of underground coal mine multihop network, needs the side combined using Reactive routing protocols and Proactive routing protocols
Method reduces the expense of Routing Protocol using agreement AODV such as the combination of agreement AODV and agreement FSR, improves handling capacity, while benefit
It is reduced and is delayed with FSR.
It is worth explanation, the equipment that individual soldier's communication terminal can will contact is grouped, can be by the voice of transmission
Or the equipment that text is sent to a certain group.
Individual soldier's communication terminal 60 or emergency command dispatching platform 30 further include camera and display, wherein camera record

Example IV
Figure 10 is a kind of flow chart for safety detection method that the embodiment of the present invention four provides, and the present embodiment is applicable to well
The case where lower operation or rescue, this method are applied to safety detection device, which is applied to individual soldier's communication terminal or emergency refers to
Dispatching platform is waved, as shown in Figure 10, this method may include:
Step 301, the sign information for obtaining characterization wearer's vital sign.
Wearer refers to the user for wearing wearable device, and the wearable device and safety detection device are wirelessly connected.Sign is special
Sign is that wearable device acquires and is sent to installation detecting device.Here, sign information includes: heart rate, respiratory rate, body temperature
Deng.
Step 302, the environmental information for obtaining locating subsurface environment.
Step 303, according to sign information and or environmental information, determine wearer if appropriate for continue underground work.
The present embodiment can determine wearer if appropriate for continuation underground work by three aspects.
In a first aspect, determining wearer if appropriate for continuation underground work by sign information:
Specifically, normal person, under rest state, heart rate, that is, pulse is 60-100 beats/min.When cardiac insufficiency, shock,
When the drug poisoning such as high fever, serious anaemia and pain, thyroid crisis, myocarditis and atropine, heart rate and pulse are significant
Accelerate.When increased intracranial pressure, dissociation, pulse slows down.
Specifically, 37.4~38 DEG C are low-heat, and 38.1~39 DEG C are generated heat for moderate for normal person, 39.1~41
DEG C be high fever, 41 DEG C the above are excessive heats.Pulmonary tuberculosis, bacillary dysentery, Bronchopneumonia, encephalitis, malaria are more common in body temperature raising
The illnesss such as disease, hyperthyroidism, heatstroke, influenza and trauma infection contamination.Body temperature is lower than normal: seeing shock, big bleeding, slowly
Property deeline, it is old and frail, Hypothyroidism, severe malnutrition, exposed and waited so long in low temperature environment.
Specifically, when tachypnea, excited, movement may occur for normal person, feed, temperature increase.Abnormal person sees
In illnesss such as high fever, pneumonia, asthma, heart failure, anaemias.When breathing slows down, increased intracranial pressure, encephalic may occur for normal person
Tumour, anesthetic, sedative use excessive, the illnesss such as pleurisy.
In conclusion whether judge sign information in normal range (NR), but since subsurface environment is different from ground environment,
The normal range (NR) of the sick sign of the normal range (NR) and normal person of the vital sign of personnel in the pit is slightly different, therefore, device for underground man car
The normal range (NR) of the vital sign of member needs independent measurement to summarize.
Second aspect determines wearer if appropriate for continuation underground work by environmental information:
Here, judge wearer if appropriate for continuation underground work by subsurface environment.If subsurface environment faces gas
Explosion immediately returns on well then needing that wearer is notified to stop underground work at once, or injects nitrogen to underground.
Analysis tendentious for underground site spontaneous fire, it is extremely important for underground work or rescue work.This reality
Example is applied according to the concentration of the gases such as the concentration of the gas in environmental information, CO, oxygen, shows nitrogen gas concn, fire by calculating
Coefficient analyzes above-mentioned gas concentration parameter and its variation tendency, and the possibility of spontaneous fire of mine is proposed on command centre's host
Property, it is scheduled for commanding and decision-making.In addition, gas explosion is to seriously threaten the accident of mine worker and rescue team member.Therefore, quasi- in time
Really judge whether gas has explosivity in disaster area, prevention gas explosion accident is had a very important significance.
The safety index of fuel gas in the present embodiment: O2 concentration is 0%~30%, CH4 concentration is 0%~100%, CO
Concentration is 0PPm~10000PPm, environment temperature is -20 DEG C~125 DEG C.
The third aspect passes through sign information and environmental information, determines wearer if appropriate for continuation underground work:
According to environmental information and sign information, the operating time of wearer is determined；Obtain wearer's having worked in underground
Time；Whether the working time is more than operating time for judgement；Wherein, it is more than operating time when working time, determines wearer
Be not suitable for continuing underground work.

One is suitble to the operating time of itself, according to environmental information and sign information in the present embodiment, determines the operating time of wearer,
It can be realized by following two method:
Optionally, according to the first default corresponding relationship of living hierachy and sign information, the sign information of wearer is determined
Corresponding living hierachy；According to the second preset relation of environmental information and environmental rating, the environmental information of local environment is determined
Corresponding environmental rating；According to corresponding living hierachy and corresponding environmental rating, operating time is determined, here, two
There is also thirds to preset corresponding relationship for grade and operating time.
Optionally, a deep learning model is established；To deep learning mode input sign sample and environmental samples, obtain
Export result；Output result and corresponding operating time sample are compared, the parameter of deep learning model is updated, until defeated
Result and the error of operating time sample be within a preset range out；Sign information and environmental information are inputted into deep learning model,
Obtain operating time.
Step 304, when determine wearer be not suitable for continue underground work when, export prompt information.
After exporting prompt information, the prompt information can be shown, or be sent to the held individual soldier's communication terminal of the wearer.
Further, this method can also include:
The illness that wearer's appearance is analyzed according to sign information determines the side for solving or alleviating the illness according to illness
Method.By taking heatstroke is target conditions as an example, the method for solving to alleviate includes: that wearer is transferred to shady and cool ventilation environment.
The above method not only can be applied to individual soldier's communication terminal in the present embodiment, but also can be applied to emergency command scheduling and put down
Platform.Since individual soldier's communication terminal can be direct-connected with environment detection equipment and wearable device, transmission speed is fast, therefore, individual soldier's communication
Terminal, which is directed to, needs the case where racing against time, such as whether individual soldier's communication terminal can judge wearer according to environmental information
It is suitble to work on；If subsurface environment faces gas explosion, all people require to flee from underground.Due to emergency command
Dispatching platform can need to transmit layer by layer with environment detection equipment and wearable device, and transmission duration can be longer, and therefore, emergency refers to
The case where dispatching platform can not be strict for time requirement is waved, for example, the judgement of the operating time in underground.
Further, this method can also include:
It obtains and detects user's posture；When the duration that the wearer is in same user's posture is more than preset duration,
Export sound-light alarm.Here, preset duration is more long, and sound-light alarm rank is higher.Here, user's posture is obtained by wearable device
It takes, and is sent to individual soldier's communication equipment.
Exemplary, individual soldier's communication terminal remains static 30 seconds or more, and individual soldier's communication terminal starts to carry out level-one acousto-optic
It alarms (intensity of sound is normal), carries out second level sound-light alarm (intensity of sound is stronger) after 40 seconds, three-level acousto-optic report is carried out after 50 seconds
