Description
Technical field
The utility model relates to a kind of controller of intelligent overturning antidecubitus air mattress, belongs to the controller technology field.
Background technology
Bedsore is because the long-term pressurized of local organization, continuous ischemia, anoxic, malnutrition occur and causes tissue fester's necrosis.The old man of long-term bed, and the patient of thereby paralysis or high paraplegia former owing to traffic accident, industrial injury etc.Because these crowd's long-term beds, health can't be freely movable, very easily Pressure Ulcers.Bedsore prevention air cushion has the effect of prevention and treatment bedsore, its mechanism is: adopt physiology and principle of dynamics, control the inflation/deflation that air pump replaces air bag by controller, thereby the rolling that makes air cushion be fluctuation-type constantly changes the implantation position of the bed person, reaches the blood circulation that improves the implantation position, the effect of air circulation.Prior art has bedsore prevention air cushion, but exist a lot of not enough, for example intelligent product is short of, can not automatically carry out aeration quantity control according to people's body weight, mode of operation is single, and operation interface is unfriendly, without from warning circuit etc., these deficiencies not only can affect the market of product self, and also can use to the patient simultaneously makes troubles.
Summary of the invention
In order to solve above-mentioned a series of technical matters, the utility model provides a kind of controller of intelligent overturning antidecubitus air mattress.
The technical solution of the utility model is: comprise control module, described control module is come air cushion is inflated by the control air pump, be connected by rotating air valve between described air pump and the air cushion, described rotation air valve is driven by stepper motor, be used for changing the inflation position of air cushion, described control module is provided with pressure monitor, described gas pressure detector is connected with the rotation air valve, and air pressure signal fed back to single-chip microcomputer, the mode of operation parameter that function button is connected with single-chip microcomputer and provides single-chip microcomputer to set, described single-chip microcomputer drives with air pump and is connected, and described single-chip microcomputer is connected with stepper motor by driving circuit.
Described control module also comprises display screen, and described display screen is connected with single-chip microcomputer, shows the parameter value of air cushion mode of operation.

Described control module also comprises constant pressure source, and described constant pressure source provides voltage to described controller.
Described single-chip microcomputer is 8 single-chip microcomputers.
Described function button is comprised of 6 buttons, the respectively switching of corresponding parameter, and the increase and decrease of parameter starts and stops.
What described air pump driving circuit adopted is bidirectional triode thyristor zero passage voltage trigger circuit.
The beneficial effects of the utility model are and can come the aeration quantity of air cushion is controlled according to body weight for humans, adopt liquid crystal display frequently, and man-machine interface is friendly, and warning circuit is arranged, and guarantee that product is more safe and reliable.
Description of drawings
Fig. 1 is the utility model control circuit block diagram.
Wherein, the 1st, control module.
Embodiment
Referring to Fig. 1, this bedsore prevention air cushion controller hardware forms and comprises control module, constant pressure source U9, described control module is provided with single-chip microcomputer U1, function button U2 and control circuit thereof, LCDs U 3 and signal circuit thereof, stepper motor U4 and control circuit thereof, rotate air valve U5 and control circuit thereof, Pressure monitoring U6 and control circuit thereof, Buzzing module U7 and control circuit thereof, air pump drives U8 and control circuit thereof, wherein, function button U2 control circuit is connected with single-chip microcomputer U1, single-chip microcomputer U1 is connected with display screen U3 signal circuit, and single-chip microcomputer U1 is connected with stepper motor U4 control circuit, and stepper motor U4 connects and air valve U5 is rotated in control, rotating air valve U5 control circuit is connected with Pressure monitoring U6 control circuit, Pressure monitoring U6 control circuit is connected with single-chip microcomputer U1, and single-chip microcomputer U1 is connected with Buzzing module U7 control circuit, and single-chip microcomputer U1 drives the U8 control circuit with air pump and is connected; Single-chip microcomputer U1 and each control circuit are connected in constant pressure source U9 and the described control module.
The course of work, referring to Fig. 1, constant pressure source is to alternating current 220V civil power process transformation, rectification, provide 5V voltage to single-chip microcomputer U1 after the filtering, LCDs U3 is after start, the above air cushion mode of operation can occur and select the interface, the user is at first by the K1 (making progress) in the function button module, K2 (downwards) key switches parameter such as the body weight value that will adjust, cycling time etc., then use K3 (increase), K4 (successively decreasing) key is adjusted the design parameter size, after selection is finished, just can press start key K5 work, single-chip microcomputer U1 is according to the model selection instruction of key-press input, then controlling air pump by pin output PWM ripple inflates the A gas circuit, simultaneously air pressure detect the U6 control circuit with regular time the interval repeatedly detect the atmospheric pressure value that rotates air chamber in the air valve U5, after amplifying, pass to single-chip microcomputer U1 and carry out the A/D processing, and the air pressure threshold corresponding with selected mode of operation, when if air pressure reaches threshold value, air pump can stop inflation, and keeps one period corresponding with the mode of operation of selecting; Then single-chip microcomputer U1 control step motor U4 drives and rotates the air valve rotation, so that A, two gas circuits of B communicate, because the air pressure in the A gas circuit is than the height of B gas circuit, gas shifts in can be from the A gas circuit to B, until A, B gas circuit air pressure reaches balance, when the pressure of air chamber does not change in detecting rotation air valve U5, A is described, B gas circuit air pressure is balance, and the equilibrium state of maintenance a period of time, time length is also corresponding with the mode of operation of selecting, then single-chip microcomputer U1 again Driving Stepping Motor U4 drive and rotate air valve U5 rotation so that air pump is aimed at the B gas circuit and to its inflation, the A gas circuit is outwards venting then.Single-chip microcomputer U1 circulation aforesaid operations, the sequenced inflation/deflation that A, B gas circuit are circulated will make springing up of air cushion undulate, thereby finishes patient's the action of standing up.
