Description
Technical field
The utility model relates to a kind of improved general hand controller, is used for the light control and the motion control of conventional accelerator, analog machine, cobalt-60 therapy machine and general treatment bed, belongs to the light in the accelerator and the control assembly of motion.
Background technology
Traditional hand controller does not possess versatility, and every kind of Medical Devices must be equipped with own special-purpose hand controller, and the hand controller signal adopts the switching value transmission, contains much information, and each motion all needs line to be connected with outside, makes the stube cable heaviness.And motion control can't speed governing, and the hand controller volume is bigger again, and surperficial button is many, and structure is loaded down with trivial details, has increased failure rate.
The utility model content
The purpose of this utility model is to provide a kind of general hand controller, and is simple in structure, easy to operate, reliability is high.
General hand controller described in the utility model, comprise housing and button, the control circuit of being made up of single-chip microcomputer, analog to digital converter and potentiometer is set in the housing, the communication terminal of single-chip microcomputer connects the control end of Medical Devices, the data input pin of single-chip microcomputer is the output terminal and the button that is arranged on the housing of connection mode number converter respectively, the input end of analog to digital converter connects potentiometer, and the sliding end of described potentiometer is provided with the speed governing knob.
Single-chip microcomputer through handling, sends by the form of communication terminal with serial signal after obtaining signal that analog to digital converter transmits.By be provided with can so that, when motion control speed governing knob mediates, when the speed governing knob when middle position rotates forward, motor just changes; When rotating backward, the motor counter-rotating.And along with the increase of the anglec of rotation, rotating speed of motor also increases, up to maximal value.
In the utility model:
The communication terminal of single-chip microcomputer adopts the RS232 standard with being connected of Medical Devices, uses six core spring wires, and designs simplification can be saved employed cable and wire.
Single-chip microcomputer can adopt AT89C51, by the operation of its control whole procedure.FLASH storer in the AT89C51 sheet can carry out electricity easily and wipe, and is in debug process, very convenient.After powering on, single-chip microcomputer is read the program in the FLASH successively, controls the work of each parts, goes round and begins again.
Analog to digital converter can adopt serial a/d converter TLC0838, takes out the signal of potentiometer by it, thereby obtains velocity magnitude and direction.
The communication terminal of Medical Devices and microcontroller communication end the RS232 standard be connected, the program setting of single chip computer AT 89C51 is common prior art, can directly use to get final product.
The general hand controller of the utility model, by in housing, being provided with by single-chip microcomputer, the control circuit that analog to digital converter and potentiometer are formed, the communication terminal of single-chip microcomputer connects the control end of Medical Devices, the data input pin of single-chip microcomputer is the output terminal and the button that is arranged on the housing of connection mode number converter respectively, the input end of analog to digital converter connects potentiometer, the sliding end of potentiometer is provided with the speed governing knob, after single-chip microcomputer obtains signal that analog to digital converter transmits, through handling, send by the form of communication terminal with serial signal, simple in structure, easy to operate, the reliability height.Can be used for the light control and the motion control of conventional accelerator, analog machine, cobalt-60 therapy machine and general treatment bed, motion control can be adopted the stepless speed regulation mode, panel is by increasing compound keys, reduce the quantity of motion control knob, save panel space, the hand controller signal adopts serial code output, saved the quantity of signal wire, hand controller and aerial lug adopt six core spring wires, and be easy to use, elegant in appearance.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is a control flow chart of the present utility model.
Among the figure: U1, single-chip microcomputer U2, analog to digital converter RP1, potentiometer SW1, SW2, button.
Embodiment
Below in conjunction with the embodiment accompanying drawing the utility model is further described.
As shown in Figure 1, the communication terminal of single-chip microcomputer U1 connects the control end of Medical Devices, the data input pin of single-chip microcomputer U1 is the output terminal and the button SW1 and the button SW2 that are arranged on the housing of connection mode number converter U2 respectively, and the input end of analog to digital converter U2 connects potentiometer RP1.
The sliding end of potentiometer RP1 is provided with the speed governing knob, perhaps is associated with speed governing knob on the housing.
Button SW1, SW2 can be buttons, also can be the compound keys groups.
Communication terminal connects Medical Devices and adopts the RS232 standard, can use six core spring wires, saves employed cable and wire.
Single-chip microcomputer adopts AT89C51, by the operation of its control whole procedure.FLASH storer in the AT89C51 sheet can carry out electricity easily and wipe, and is in debug process, very convenient.After powering on, single-chip microcomputer is read the program in the FLASH successively, controls the work of each parts, goes round and begins again.
Analog to digital converter adopts serial a/d converter TLC0838, takes out the signal of potentiometer RP1 by it, thereby obtains velocity magnitude and direction.
Principle of work: the effect of analog to digital converter U2 is the displacement signal of potentiometer to be become 8 binary voltage signals of size variation, and sends single-chip microcomputer U1 to.This signal has not only been represented the sense of rotation of motor, has also represented the rotational speed of motor.After single-chip microcomputer U1 obtains signal that analog to digital converter U2 transmits, through handling, send with the form of serial signal.
Rotate to be example by being provided with frame, when potentiometer RP1 mediated, its output valve was 128, and this moment, motor did not change.When rotational potentiometer RP1 forward, it was worth greater than 128 o'clock, and motor just changes, and this value is big more, and motor speed is fast more; When rotational potentiometer RP1 backward, it was worth less than 128 o'clock, the motor counter-rotating, and this value is more little, and motor speed is fast more.Light control is adopted " the table tennis formula " key mode, promptly click, lamp is bright; Click, lamp goes out again, and is transferred to single-chip microcomputer U1 by switching value.
Can also be with compound keys group 1 (button SW1) effectively the time by being provided with, speed governing knob controlling collimating apparatus, frame, bed vertically, bed laterally, bed lifting, bed revolution motion.Press compound keys group 2 (button SW2) effectively the time, speed governing knob controlling collimating apparatus Y is to, Y1, Y2, X to, X1, X2 motion.
As shown in Figure 2, be a kind of control flow chart that can realize of the present utility model.Hand controller start back self check is if unusually just send false command, if normally just can carry out light control or motion control and send relevant instruction.
