In σmaxOn the maximum section of moment of flexure, and the place farthest from central shaft.Therefore the calculation formula of maximum (normal) stress is
Direct stress is directly proportional to moment of flexure, and moment of flexure is bigger, and direct stress is bigger, at the same direct stress also with ymax/IZIt is relevant, i.e., with cutting
The size and dimension in face is relevant.Then
Formula is rewritable to be
W is bending resistant section coefficient, and the shape in its section is relevant, and account bar section is shaped as circle then
Power FB on the left of cross bar is not fixed, mainly calculates the power that cross bar can bear using formula, so as to really
Determine the coefficient of elasticity and length of spring, make when power is excessive, tent can be collected normally, without damaging cross bar.
The allowable stress of bar is 205pa, and length 200mm, diameter d are 10mm.The weight of bar is 14N, so maximum curved
Square is.
Bending resistant section coefficient is
Bending resistant section coefficient is
Try to achieve
FBmax=93.57N
So
|Fs|max=FB+ G=93.57+14=107.57N
The elastic force that spring is in elongation state can not be too small no more than 107.57N, elastic force, and otherwise tent is easy to meeting
Automatic reduce is unable to normal use, and it is 100N tentatively to take elastic force.The coefficient of elasticity of spring takes 2000N/m, and the length of spring takes
150mm。

Transmit-receive radio road is connected with P1 mouths, when single-chip microcomputer output is low level, infrared transmitter normal work.Infrared radiation receiving circuit
It is connected with P3 mouths, when P3 mouths receive low level, warning device is not alarmed then；When there is unknown object to swarm into, infrared ray receives dress
Put and do not receive infrared ray, the level for reaching P3 mouths is then high level, and now single-chip microcomputer will make a response, what single-chip microcomputer was sent
Square-wave pulse signal exports through P3.7 mouths, and warning circuit receives the signal that single-chip microcomputer is sent, LED flicker, and loudspeaker send sound
Sound is alarmed.
Inverting amplifier is carried inside 80C51, is primarily used to form oscillator.When using single-chip microcomputer, draw at two

Warning circuit circuit receives pulse signal and starts warning device.When alarm activation, LED flashes, and loudspeaker send sound
Sound prompting is dangerous.
Software control process corresponding with above-mentioned hardware circuit described in detail below：
Whole control software includes：Main program, pulse signal generating routine, interrupt service routine.It is mono- that it is stored in 80C51
In piece machine, the control mode of whole program is when detecting that someone swarms into, and low and high level is exported at intervals of 1 second by P3.7 mouths
Pulse signal goes to drive sound light alarming circuit (can once realize by making P3.7 mouths negate every 1 second).
Specifically, 1 second time can allow timer to repeat ten realizations of timing 100ms.It can be circulated with register R1
Counter initial value is 10.Programmed using interrupt mode, whole program is made up of main program and interrupt service routine two parts.
The function of main program:Play monitoring, be mainly used to judge whether that someone swarms into, in the reception whether of infrared ray
It is disconnected.Start in program, system initialization judges whether that someone swarms into after terminating, and is alarmed if having, if without if return to upper level after
It is continuous to judge whether that someone swarms into.
Pulse signal generating routine flow：Waited by timing 100ms, and continuous timing finally gives a cycle 10 times
The square-wave signal using 1s as the cycle, repeat this process, finally give the square-wave pulse signal in a row 1s cycles, this final row arteries and veins
Rush signal and exported to be connected with warning circuit by single-chip microcomputer P3.7 mouths and drive light emitting diode to be flashed with 1s frequencies and buzzer call
Alarm.Interrupt service routine is whether to judge timing to the time, and the input of warning circuit is negated on time.
In addition, the core parts of sound control circuit are Electret condenser microphones, voice signal is converted into 80C51 by Electret condenser microphone can
With the signal of identification.Light-operated circuit is mainly to compare integrator work by photo resistance and twin voltage, and photo resistance is main
The break-make of control circuit.Twin voltage compares the voltage that integrator inputs by comparing both positive and negative polarity, exports low and high level.
Wherein, whole control principle is：The signal input of sound control circuit is P3.5, and light-operated circuit then inputs through P1.6 mouths
To single-chip microcomputer, two circuits control LED simultaneously, and during the day because illumination acts on, the resistance very little of photo resistance can be ignored
Disregard, circuit is in the conduction state, and the delivery outlet output high level of light-operated circuit, no matter whether surrounding has sound, LED is not
It can light.When the same day is dimmed sound, the resistance of photo resistance tends to be infinitely great, causes light-operated circuit to belong to off state, light
Circuit output low level is controlled, if having sound to send around having, Electret condenser microphone receives voice signal and is converted into electric signal, electricity
Signal enters SCM system via P3.5 mouths, and now LED is bright, after voice signal disappears, the bright 60 seconds automatic extinguishings of LED
Go out.
In the present embodiment, the resistance size of the photo resistance of light-operated circuit is inversely proportional with intensity of illumination, and daylight is strong
Degree is about in 0-100lx or so, therefore the resistance very little of photo resistance.The operation principle of voltage comparator is that to compare both positive and negative polarity defeated
The voltage entered, when positive pole is more than cathode voltage, then export high level.Light-operated circuit inputs a signal into monolithic by P1.6 mouths
Machine.The voltage difference of both positive and negative polarity input is higher away from bigger voltage comparator sensitivity, and slide rheostat is exactly to be used for adjusting sensitivity
's.
When photo resistance is irradiated by light constantly, resistance value very little can be ignored, and circuit is defeated equivalent to path, voltage ratio
Device goes out high level.When without stronger light, photo resistance tends to infinitely great, voltage comparator output low level.Electric signal leads to
Cross P1.6 mouths and be input to single-chip microcomputer.In P1.6 mouths input high level on daytime, P1.7 mouths are caused to export high level, it is whether sound
Sound, light emitting diode also will not be bright all without conducting, lamp.
In the present embodiment, Electret condenser microphone is the critical elements of sound control circuit, and sound is changed into by Electret condenser microphone
Electric signal.Electric signal is exaggerated by special circuit successively, the electric signal that the role transformation of filtering can identify into single-chip microcomputer,
Electric signal is input to single-chip microcomputer by P3.5 mouths.
Because automatic monitoring warning module and audio-switch module are connected on 80C51 single-chip microcomputers simultaneously.Therefore, can pass through
Program is write, monolithic function is rationally and effectively controlled two modules while works.
In preferred embodiment, the intelligent tent can also include：Solar cell 302 and battery；It is described
Solar cell is arranged on the outside of the tent body, and the solar cell is connected with battery, is filled for the battery
Electricity.Below in conjunction with the application demand of reality, the selection calculating process of the solar cell and battery is described in detail：
The ideal power of solar cell is also the peak power (P of solar cellmax=open-circuit voltage x short circuit currents),
In solar cell in actual use, rated power (P) is less than ideal power, because the function of solar cell
Realization be to be determined by the intensity of illumination, and the intensity of illumination is unstable, so in the different periods, its power is
Change, the power output (u) that can finally draw solar cell according to experiment actually only has 70%, so as to cause its specified work(
Rate is consistently less than ideal power.Because electric energy caused by solar cell is used directly to band dynamic load, load is set normally to transport
OK, it is necessary to make the electric energy that solar energy exports equal with the rated power loaded, then Pr=0.7Pmax.Therefore solar cell power
Selection should be according to the rated power of load, i.e. Pmax=1.43P.
Select rational solar cell power, it should according to the rated power of load, only in this way, solar cell
Power output could make load normal work with the consumption power-balance of load.The generating work(power of solar cell simultaneously
It is not only relevant with residing geographical position, it is also relevant with the residing period, therefore during selection solar cell, should consider
Actual conditions.
Because solar cell is to utilize optical energy power, it is therefore necessary to which electricity on daytime, which is stored, to be made for night
With at this moment having to a rationally choosing then battery.
The generated energy of solar cell：
The effective light application time x generating dutations of M=generated outputs x
Then its daily generation can be written as again：The effective light application times of M=output currents (I) x, i.e.,
C=IH (AH)
The capacity of battery is the product of discharge time and discharge current, i.e.,
C=IH (AH)
Again because P=IU, then
For the capacity of accurate calculating accumulator, the charge efficiency of battery is taken into account, the charge efficiency of battery
It is to be determined by charging modes, the charge efficiency of the battery typically used is 65%-80%.The height of charge efficiency under normal circumstances
Low to be weighed by charging interval rate and current rate, the time longer charging current of charging is smaller, and electric energy conversion ratio is higher,
Offset is higher.
Select monocrystalline silicon battery component, peak power output Pmax=25W, rated voltage U=17.2V, peak point current are
1.45A, open-circuit voltage 21V, short circuit current Isc=1.5A, it is assumed that effective light application time is 2 hours, solar cell power generation effect
Rate is u=0.7, and the offset of battery is 1.4, then：
The generated energy of solar cell：
M=Pmax× H × u=25 × 1 × 0.7=17.5W
Then the available capacity of actual battery is：
The accumulator capacity then selected is 1Ah or so, the current production technology comparative maturity of solar cell, the rule of battery
Lattice and species are more and more, alternative also increasing.Under normal circumstances, the output voltage of solar cell is than battery
Height, because the charging of battery is lossy, charging voltage more high recharge efficiency is higher.
The light that do not have thing to block sunshine is should be noted that during solar recharging, should when at night or cloudy
One commutation diode of series winding in circuit, prevents that battery is inversely put a little when solar energy from dropping under voltage.
