The specific embodiment
Below in conjunction with drawings and Examples control procedure of the present utility model is further described:
When turning on the power switch, it is bright that light emitting diode sends power supply indicator, and system at first carries out self check, self check by after enter menu parameter duty be set, can require relevant parameter is set according to reality like this, enter duty.Self check not by or make mistakes in the course of the work, system will show error message, and this wrong method is corrected in prompting.When entering actual working state light emitting diode will show the dropping liquid situation both every flicker once, and every one of buzzer is rung once, also can not ring, and is decided by setting.When reporting to the police, buzzer can send continuous beeping sound and warn.Control procedure is: by single-chip microcomputer P2
6Mouth sends low level signal, and this moment, source current was through R2
8, D
8Luminous tube is to P2
6Mouthful, D
8Shinny.If P2
6Mouth sends a high level signal, and electric current will be cut off, and luminous tube extinguishes.Dropping liquid signal and power supply signal are together with a circuit.When sound alarm circuit need send interrupted beeping sound, at first by P2
7Mouth is sent a high level signal, thereby drives Q
2Conducting, electric current is through Q
2, buzzer to ground, make the buzzer sounding.As single-chip microcomputer P2
7The a succession of pulse signal of mouth output, this equipment will send a string beeping sound and report to the police.
Single-chip microcomputer is to the control of matrix display: to account for the I/O mouth more because of this equipment, so this equipment adopts the indirect addressing mode for the control of display.During work by P
0Data are sent in oral instructions, P
2Control signal is sent in oral instructions.Thereby vacate more I/O mouth, both guaranteed control, guaranteed that again colourful function and hommization show other parts.
Button control has partly adopted matrix to add interrupt circuit, can cause that all " keyboard interrupt " causes keyboard scan as long as press any key and touch any position sensor.And the execution relative program, thereby finish function corresponding and task.When not having button and touching position sensor, single-chip microcomputer will not be affected.Available more time is finished intelligent task.
The control procedure of automatic infusion control is as follows: by single-chip microcomputer P1
0The pulse signal that mouth sends is through pulse amplifier Q

7Transistor is closed, and motor is stopped, and finishes tube for transfusion automatic valve closing motion.
The process that single-chip microcomputer detects the motor gyration is: a grating wheel is housed on the rear axle of motor, and dividing equably on the grating wheel has 18 gratings, average 20 ° one on grating.Respectively adorn an infrared transmitting tube and infrared receiving tube in the both sides of grating wheel, infrared transmitting tube is launched infrared light by grating wheel to receiving tube always.When halo rotated with motor, 20 ° of revolutions were just sent out a signal to infrared receiving tube, and this signal is through U2
DAmplify integer and be behind the discernible signal of single-chip microcomputer input single-chip microcomputer INT1 mouth and count and compare, just produce the signal of control motor rotation.
Single-chip microcomputer constantly receives the fluid flow rate signal of detection and the angular signal that rotary angle transmitter sends, and single-chip microcomputer constantly calculates and controls motor and rotates, till reaching the flow that will control.
The power pack of this device, the power supply of this equipment have three kinds of modes: (1) by 110 volts-240 volts, 50-60Hz is by charger, to this equipment charge and power supply.(2) directly insert attaching plug to this equipment charge and power supply by 12 volts of direct currents.(3) directly by this equipment charge lithium battery power supply.Because this equipment needs the DC voltage of 5V, the work of lithium battery is the 2.9-4.2 volt, along with battery consumption voltage will be more and more lower.In order to ensure that this equipment provides a stable voltage, this equipment is by the power supply of lithium electricity the time, by U5
AThe boost DC-DC translation circuit that integrated circuit, MC34063A are formed provides the DC voltage of a 5V all the time to this equipment.When supply voltage is again up to 12 volts when in charging, exceeded the normal power supply voltage of this equipment.The reduction voltage circuit of forming by WY integrated circuit 7805.The voltage that will exceed this equipment stabilizes to the 5V running voltage of this equipment.Power circuit can be worked this equipment in the scope of 2.7-12 volt.
