The specific embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to invention:
As shown in Figure 1, medical transfusion wireless alarm system, it is characterized in that comprising data acquisition and data transmission terminal, data receiving terminal and data management terminal, wherein said data acquisition and data transmission terminal and data receiving terminal radio communication, data receiving terminal is connected with the data management terminal by the RS232 interface.
Data acquisition and data transmission terminal
The metering of transfusion overall weight as shown in Figure 2.In this system, high-precision LOAD CELLS J2 (precision is 1 gram, 1～5 kilogram of the scope of weighing) is lower to hang infusion bottle, and the variable signal of liquid quality becomes the differential signal of telecommunication through A1+ and A1-output in the infusion bottle after LOAD CELLS picks up.This signal is through inputing to the A/D conversion port of SN8P1917 single-chip microcomputer after the Filtering Processing, wherein R6 is thermo-sensitive resistor, and circuit is played temperature compensation function.SN8P1917 converts the analog electrical signal of LOAD CELLS to digital signal.
Data storage cell is mainly stored be weigh that range of weighing selection, character code, Unit code, nominal data, start-up picture when showing selected, warning comparing data etc. initial data.The data such as range of weighing selection, character code, Unit code, nominal data, start-up picture selection are system data, can be burned onto in the storage chip by cd-rom recorder is disposable.The warning comparing data is for selecting to arrange data, depending on the large bottle of transfusion and nurse station apart from distance by the button setting.For saving input/output port, generally adopt Serial E
2PROM, the AT93C46 that native system adopts.AT 93C46 is the memorizer of the electric erasable of 1K byte.CS: be chip select pin, Low level effective.SK: be control clock foot.DO: be the data output pin.DI: be the data input pin.ORG: be 8 bit data and 16 data selections, ORG=1,16 bit data; ORG=0 is 8 bit data.The control sequential all need satisfy the sequential requirement of serial communication.As shown in Figure 3.
In native system data acquisition and the data transmission terminal, button is more, and the I/O of SN8P1917 is limited, and therefore design selects HD7279A to realize keyboard matrix.Keyboard mainly comprises: (1) starts/closes button; (2) Conversion of measurement unit button; (3) peeling (making zero) button; (4) demarcate button; (5) the affirmation button is set; (6) numeral is removed button; (7) manual/auto selection; 17 buttons such as (8) 0～9 digital keys, as shown in Figure 5.Demarcating button is system's button, uses when system calibrating.0～9 digital keys is in order to the weight of address digit (being the disease bed label) that transfusion patient is set and transfusion and alarming value is set, and for distinguishing this three kinds of values, adds identification code before these three kinds of values.The first bit digital is 9, the data representation address digit of back, and for example 90010, the expression address digit is 10; The first bit digital is 8, the weight of the data representation of back transfusion, and for example 82000, the weight of expression transfusion is 2000 grams; The first bit data position 7, the alarming value that the data representation of back arranges, for example 70205, during weight to 205 gram of the weight (comprise infusion bottle, infusion bottle is generally standard weights) of expression transfusion, system sends transfusion terminated call signal.After these data inputs, automatically deposit in the AT93C46 memorizer.
Be designed with HD7279A keyboard display driver chip in native system data acquisition and the data transmission terminal, can drive 88 sections LED charactrons, but the power consumption of charactron be relatively large, so adopt LCD to show in the native system.The built-in 1/2 bias voltage ratio of SN8P1917 single-chip microcomputer, the liquid crystal drive of 4*12 position can show 5 pen section numerals.VLCD: be LCD driving power input pin; COM0～COM3: for LCD drives common port; SEG0～SEG11: for LCD drives the section foot.As shown in Figure 4.LCD1 is 8 sections segment type LCD, and concrete numbers and symbols is according to different system designs.
Each data acquisition of native system and data transmission terminal are according to certain time slot transmitting system data.When alarming value that the weight of transfusion liquid arranges less than system, launch terminal starts the alarm calls program automatically.System data comprises address digit data and the last weight two parts of transfusion, and 8 bit address numbers are front, and 16 weight datas are rear, and totally 24, system data adopts wireless signal transmission.The call circuit principle as shown in Figure 5.When P5.2 is high level, the VT2 saturation conduction, by the high-frequency oscillating circuits starting of oscillation that VT1 and inductance L 2 etc. forms, electromagnetic wave is launched by antenna E.When P5.2 is low level, VT2 cut-off, the high-frequency oscillating circuits that is comprised of VT1 etc. is owing to not having power supply and not starting of oscillation.Therefore SN8P1917 constantly changes the height of P5.2 level by program, just can control the vibration of oscillating circuit and stop, thereby the information that will send is modulated on the high frequency carrier.Modulation signal is by the output of P5.2 end, and this signal is square wave.The native system designed, designed a kind of coding standard, utilize the width of square wave to express data message, thereby realize transmitting and receiving of data.
Among Fig. 6, provided the coding protocol that native system is formulated.The pulsewidth TA=200us of pulse A among the figure, this pulse representative " 0 "; The pulsewidth TB=400us of pulse B, this pulse representative " 1 "; The pulsewidth TC=600us of pulse C, this pulse represents initial symbol.When transmitting data, transmit exactly the combination of these 3 kinds of pulses
Data receiving terminal
Data receiving terminal at first gets off the signal coupling of launch terminal emission, and is demodulated to original data signal.Circuit theory diagrams as shown in Figure 7.VT1, VT2 have formed receiving demodulation circuit, jointly consist of the reception tuning circuit and carry out the detection demodulation by VT1 and relevant element, then the signal of VT2 after to demodulation amplifies, and carrying out shaping at the corresponding signal of resistance R 8 output to homophase and the end of oppisite phase of operational amplifier A 1, the square wave of the outfan outputting standard of A1 is connected to the P2.0 mouth of AT89S52.P2.1 and S0 join, if S0 is not pressed, program will loop warning, vibration prompt; After S0 was pressed, program was returned initialization.Luminous tube VD2, buzzer B1 are connected with P2.2, P2.3, P2.4 respectively with vibrator YD, by send the different pulse signal of frequency to these port lines, realize sound, flash of light and vibration prompt.
Data receiving terminal connects calling sick bed numerical signal (address information) is presented on the LED, will receive that simultaneously transfusion liquid weight data signal and sick bed numerical signal are sent to host computer by the RS232 mouth.Host computer is placed in the caretaker room of nurse station.Be composed of system program in the host computer, system program will receive that each system data processes and pass through interface display.Interface display sick bed number and the last weight of transfusion that dynamically shows each sick bed, the staff of nurse station can control the transfusion situation of each sick bed in real time.
Simultaneously, data receiving terminal can be designed to miniaturization like the same migration terminal of mobile phone, and medical personnel can carry.The migration terminal receives warning message with the form prompting medical personnel of acousto-optic, and the transfusion address information (sick bed label) that medical personnel check warning by " reading " key on the migration terminal is deleted the transfusion address information of having served by " removing " key.As shown in Figure 8.
The data management terminal
The data management terminal is based on PC, and PC manages the data that data receiving terminal sends by the RS232 mouth.Show corresponding transfusion address information (sick bed label) and the last information such as weight of transfusion liquid of reporting to the police at computer monitor, and patient's relevant medical information.Such as Fig. 1.
