Detailed description of the invention
Below in conjunction with the accompanying drawings, the present invention is further illustrated.
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and be embodied as
Mode, is further elaborated to the present invention.Should be appreciated that detailed description of the invention described herein is only in order to explain this
Invention, is not intended to limit the present invention.
As Figure 1-5, this detailed description of the invention adopts the following technical scheme that it comprises sensing harvester, photoelectricity
Change-over circuit, decoding conversion module, alarm, central processing unit, wireless transport module, signal conversion module；Sensing is adopted
Storage is connected with photoelectric switching circuit, and photoelectric switching circuit is connected with decoding conversion module, and decoding conversion module is with alarm even
Connecing, central processing unit is connected with alarm, wireless transport module, PC end respectively, and wireless transport module is with signal conversion module even
Connecing, signal conversion module is connected with PC end.
Further, in described alarm, set 3v built-in power, add 5819 Schottky diodes simultaneously and put
Power down protection, Access Control circuit.Switch is opened, and sends an acoustic alarm, and green indicating lamp lights, and infusion alarm starts work
Make.Use electronic cell is conveniently replaceable, and can increase the service life, and reduces volume, reduces cost.
Design on control circuit: infusion alarm uses processor of single chip computer, is greatly reduced original paper number and circuit board size,
Reduce system cost.
First power supply is carried out voltage stabilizing and transformation, the voltage that output is suitable for, powers for circuit.Testing circuit is mainly by photoelectricity
Sensor forms, and the change in voltage of photosensitive sensor is input to control circuit, and control circuit is according to the change in voltage inputted
The difference of signal thus export low and high level, be input to warning circuit, warning circuit, at infusion-completed alarm, reaches transfusion report
The effect of alert device.
Warning circuit designs: transfusion state is shown by instruction status circuit.Normal infusion state instruction green light is interrupted
Glittering, warning circuit is not reported to the police；When transfusion will drip off state, state instruction red light is interrupted glittering, and buzzer sends report simultaneously
Alert.The rectangular pulse produced by 555 intervalometers composition astatic multivibrators controls the step cry of loudspeaker.For
Multivibrator can determine the intermittent time according to T=0.7* (R12+2R13) * C1, and ON time is T1=0.7* (R12+
R13) * C1, charging interval T2=T-T1 can be calculated ON time by circuit diagram: T=0.7* (510K+2*20K) * 330uF
=1.235KHZ.The function of 555 intervalometers is mainly determined by two comparators.The output voltage control RS of two comparators triggers
Device and the state of discharge tube.Plus voltage between power supply and ground, when 5 feet are unsettled, then the homophase input of voltage comparator C1
The voltage of the inverting input that voltage is 2VCC/3, C2 of end is VCC/3.If the voltage triggering input TR is less than VCC/3, then
Comparator C2 is output as 0, rest-set flip-flop can be made to put 1, make outfan OUT=1.If the voltage of threshold value input TH is more than
2VCC/3, the voltage of TR end is more than VCC/3 simultaneously, then C1 is output as 0, and C2 is output as 1, can be set to 0 by rest-set flip-flop, makes defeated
Go out is 0 level.
Wireless network transmissions designs: alarm signal output transmission uses PT2262/2272 to be that a kind of CMOS technology manufactures
The general coding-decoding circuit of low-power consumption low price, PT2262/2272 at most can have 12 (A0-A11) three-state address end pins (outstanding
Sky, connects high level, connects low level), combination in any can provide 531441 address codes, and PT2262 at most can have 6 (D0-D5) data
End pin, the address code of setting and numeric data code, from 17 foot Serial output, can be used for radio transmitter.
1. coding chip PT2262: the coding signal sent by: address code, numeric data code, synchronous code form one complete
Code word, after decoding chip PT2272 receives signal, its address code is after twice is compared verification, and VT foot just exports high level,
Meanwhile corresponding data pin also exports high level, if transmitting terminal presses & hold always, coding chip also can be launched continuously.
When transmitter does not has button to press, PT2262 disconnects power supply, and its 17 foot is low level, so the height of 315MHz
Frequently radiating circuit does not works, and when there being button to press, PT2262 obtains electric work, and its 17th foot exports modulated serial number and it is believed that
Number, when the high frequency transmission circuit starting of oscillation that 17 feet are 315MHz between high period and launch constant amplitude high-frequency signal, when 17 feet are low flat
The high frequency transmission circuit of period 315MHz stops oscillation, thus high frequency transmission circuit receive completely control in PT2262 17 feet output
Digital signal, thus high-frequency circuit is completed amplitude keying (ASK modulation) and is equivalent to the amplitude modulation that modulation degree is 100%.
PT2262/2272 is that chip is launched/received to a pair band address, the wireless remote control of data encoding function.Wherein launch
Carrier oscillator, encoder and transmitter unit are integrated in all over the body by chip PT2262-TR, make radiating circuit become the most succinct.
While PT2272 receives signal, 17 human hair combing wastes the high level gone out gives the P2.7 mouth of single-chip microcomputer, at this moment monolithic
Machine just sends, to PT2262, the data come and processes.It is contemplated that to unlatching type less than the remote control distance of L4 latch-type, have
Time only have the half of latch-type to be even less than, and occur that signal receives unstable phenomenon because under unlatching state,
Remote signal needs synchronization per second about 30 times, when single-chip microcomputer produces interference to it or has other burst to disturb, and equipment
The interference produced after energising itself can make remote signal interrupt, so that system is operated in the labile state of a kind of jump.Institute
We used the PT2272 (L4) of latch-type, data guarantor for some time while receiving signal in this circuit arrangement
Stay.When launching blackout, the data output end of PT2272 still keeps original state, until next time receives new signal
Input.
The running voltage of SP receiver module is 3 volts, quiescent current 2mA, and it is Armstrong circuit, receiving sensitivity
For-105dbm, reception antenna is preferably the wire of 25～30 centimetres, it is therefore desirable to erect.Receiver module itself is without decoding
Integrated circuit, therefore receiving circuit is only a kind of assembly, only apply in physical circuit, carry out secondary development competence exertion should
Some effects, this are designed with lot of advantages, and it can coordinate with various decoding circuits or single-chip microcomputer, design circuit side flexibly
Just.
The operation principle of this detailed description of the invention is: uses single-chip microcomputer for processing chip, utilizes photoelectric sensor to transfusion
In bottle, residue medicinal liquid is monitored, and will drip off with warning circuit instruction medicinal liquid, then warning message by network transmission in time
Notify medical worker.Further, show, in nurse station, berth of reporting to the police accordingly.When medicinal liquid reaches alarm limit, send chimes of doom also
And display lamp variable color.Setting battery in infusion alarm, when battery electric quantity is too low, display lamp quits work.And infusion alarming
Device low cost to be had and volume are little, it is simple to use, the advantages such as capacity of resisting disturbance is strong, little power consumption.
The above, only in order to technical scheme to be described and unrestricted, those of ordinary skill in the art are to this
Other amendment or equivalent that bright technical scheme is made, without departing from the spirit and scope of technical solution of the present invention,
All should contain in the middle of scope of the presently claimed invention.
