Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
Overall system architecture schematic diagram as shown in Figure 1, intelligent transfusion control system of the present utility model includes constituting as follows module: drips speed measurement module, drip speed control module, motor control module, power module, Level Detection alarm module, monitoring temperature management module and man-machine interaction management module composition, its core is controlled work around single-chip microcomputer, and whole system is divided into sensor detecting portion and intelligent control part.
Sensor detecting portion utilizes photoelectric sensor, temperature sensor that the signal detected is converted to the signal of telecommunication that controller can distinguish, sensor detection circuit includes three circuit modules: drip speed measurement module, Level Detection alarm module, monitoring temperature management module.
The signal of telecommunication that control device in intelligent control part exports according to sensor transformation carries out logical judgment, control speed and the display of charactron of drop, completing each task such as automatic detection, automatic speed regulation, digital-scroll technique and warning function of transfusion apparatus, intelligent control part mainly includes four circuit modules: single-chip microcomputer entirety control module, drip speed control module, motor control module, man-machine interaction management module.
AT89C52 selected by core single-chip microcomputer, includes the EEPROM of 4K byte, it is simple to the development stage repeatedly debugs and revises；For improving system reliability, using X25045 to realize hardware monitoring function, this chip provides 512 bytes EEPROM to preserve important systematic parameter.Whenever system power failure, power on after, by serial clock outfan, important systematic parameter is read specific RAM district, makes program recovery properly functioning.
A speed measuring circuit figure as shown in Figure 2, drips a speed measurement module and utilizes infrared tube pulse counting method to complete drop data acquisition and tachometric survey, and reception is managed the most relative with transmitting tube, when dripless is dripped, receives pipe and receives signal, output low level；When having drop to drip, the water droplet fallen has stronger diffuse-reflectance, absorption and certain disperse function to infrared light, cause the bigger change receiving light intensity, receive pipe and can not receive stronger signal, producing a longer pulsation, need through one-level Schmidt trigger shaping, the pulse signal of one forward of output gives singlechip interruption mouth, dripping of drop of measuring that the most just can be correct counts, i.e. the speed of drop.
A speed control circuit figure as shown in Figure 3, drip speed control module and receive the data dripping speed measurement module, medicinal liquid rate of titration is controlled, motor is installed a connecting rod, the other end of connecting rod meets switch S1, whenever motor rotates a circle, switch S1 closes once, then just can send into a count signal by the P3.2 mouth of single-chip microcomputer, within the unit interval, observe count value i.e. can get the rotating speed of motor, thus obtain a feedback quantity, export certain signal and drive motor, control the forward or reverse of motor, and then drive rising or falling of liquid containing bottle to regulate the height of liquid level in tube for transfusion and i.e. control the speed of drop.
Drip speed measurement module to be all connected with single-chip microcomputer with a speed control module.
Circuit for controlling motor figure as shown in Figure 4, circuit uses the switch driving circuit of H type, and whole circuit can be divided into two-stage: the first order connects the I/O mouth of single-chip microcomputer, with penetrating a grade driving force for follow circuit high current；The second level is only drive circuit, and when P3.0 is high level, Q5 turns on, and Q3, Q7 turn on, and the voltage at motor two ends is+5V, and motor rotates forward；When P3.1 is high level, Q6 turns on, and Q4, Q8 turn on, and the voltage at motor two ends is-5V, and motor inverts.Motor control module receives the liquid drop speed data that single-chip microcomputer transmission comes, the speed speed processed by single-chip microcomputer, velocity error according to the velocity amplitude set with current drop determines the forward and reverse of motor, realize, to the control dripping speed module, making speed maintain stable input level according to preset program.
Liquid level detection circuit figure as shown in Figure 5, Level Detection alarm module completes, to the detection of height of liquid level in tube for transfusion, to set early warning liquid level, when liquid level is higher than this early warning liquid level, do not report to the police, drip a speed measurement module and do as usual picking rate information sending into inside single-chip microcomputer；When liquid level is less than this early warning height, triggers alarm device, report to the police, remind doctor to guard in time, prevent the blood backflow phenomenon caused not in time because of monitoring.
nullMonitoring temperature management module uses temperature sensor DS18B20 to carry out the collection of temperature data，And be combined with each other with man-machine interaction management module，Module is managed by posture current for patient by Bluetooth signal transceiver module and monitoring temperature、The transfusion part distance away from tube for transfusion、The information such as the change of patient fluid infusion position body temperature are transferred to single-chip microcomputer，The relatively difference between preset temperature value and actual temperature，By increasing transfusion part temperature-adjusting heating device in system peripherals and utilizing program predetermined in single-chip microcomputer，Automatically the most suitable transfusion speed required for this patient's current state and regulation temperature are calculated，And be shown to manage terminal by speed and temperature information by keyboard and charactron display module，Via voice communications module, the information change of this patient is notified attendant physician，The collection to patient status information is completed with this、Input、Transmit、Feedback and remotely control，Patient is made to obtain optimal transfusion state.
Keyboard as shown in Figure 6 and digital pipe display circuit figure, in native system, keyboard and charactron display module use three LED seven segment digital tubes display liquid drop speed, transfusion temperature, patient temperature information, charactron uses common cathode, owing to the electric current of AT89C52 single-chip microcomputer each I/O mouth only has 1 2mA.So all adding reverse driven in bit code and segment encode, keyboard uses key switch to connect on P1.0, P1.1, P1.2 mouth respectively through pull-up resistor, play determine, upper mediation downward effect, often by upper mediation down key, setting speed value increases one respectively and subtracts one, single-chip microcomputer connects 12MHZ crystal oscillator, it is provided that system clock base value, and RESET connects reset button.
This charactron has low energy consumption, low-loss, low pressure, life-span length, advantage ageing-resistant, that environmental requirement is relatively low to external world；Button uses single-row three buttons；Charactron uses BCD to encode display digit simultaneously, and easily, resource occupation is less in program compiling.
