The main control unit will dream of this: ι to the horizontal state of the special corresponding to the corresponding control; =,: special: the second terminal of the key is replaced by the motor device to drive the doctor's advice% And, and control the drive of the device to the rapid gravity: the motor device in the head block of the bed, so that the motor device in operation of the horse will not pass the feedback signal from the ^ ^ feedback signal to the main control unit. When the medical bed is in operation, the main control star-i is lowered to a position close to the operating speed of the horizontal plane; the w degree modulation function is used to control the motor device to achieve the purpose of the impulse. In the second embodiment of the root, when the head block of the hundred-bed bed different from the first embodiment is now close to the horizontal M331371, the main control unit will provide a corresponding control signal again to control the selection. The switch is switched back to the first winding of the second terminal of the motor device, so that the speed of the head block of the medical bed is restored to normal for buffering purposes. [Embodiment] The present application is applicable to each Medical beds in medical institutions, especially medical beds with automatic control systems. When medical personnel want to perform emergency medical treatments such as CPR on patients, an external control device can be used to make patients feel uncomfortable. In this case, the medical bed is automatically and quickly restored to a horizontal state. Please refer to the first figure, which is a block diagram of the control system for controlling the lifting speed of the medical bed in the present case. The system comprises a main control unit. 10. A driving unit 20, a switching unit 30, and a motor unit 40. The main control unit 10 is coupled to the driving unit 20, the switching unit 30, and the motor unit 40. The driving unit 20 is also coupled to the switching unit 30 and the motor. The unit 40 is connected to the motor unit 40. The main control unit 10 is configured to generate a control signal to control the entire medical bed after internal calculation according to an external control command (contro 1 command). The lifting operation of the display, that is, the operation of the motor unit 40 causes the medical bed to be inclined, curved, raised or lowered. Therefore, the user can input a control command for controlling the tilting, bending, ascending or descending state to the main control unit 10 through an external controller (not shown) disposed around the medical bed. wherein the external controller is set There is a special button (not shown), your J female cardiopulmonary resuscitation #f (cardio pulmonary resuscitation, 7 M331371 cp R) fast name ugly, etc. When the Weir bed will be rendered by the original = use this CPR fast new, Medical disease can be automatically restored to a horizontal heart with a square #" or a tilted state: the treatment of the patient (10). According to ΐΐ::20, at least one driving circuit (not shown) is used to generate the peak according to the control signal provided by the technical system to drive the motor single-. Medium _ less - two two, set one::::r (four) single two = r so 'drive unit 2 ◦ can use the selected motor device, further to touch the motor unit 40 + _ ^ for the motor t Set the power required for operation. The device has a 2 to 匕: a motor device, and each of the motor devices operates normally. The first winding is used to control the speed of the control group to control the speed of the operation; and the second winding speed is operated to operate, that is, the device is faster than the preset speed, so that the motor is strong and the motor is strong. The drive signal can be used to drive the horse's clothes to perform a forward or reverse action. Starting i: When: Use = at this time the head block of the medical bed surface is shown as Yang, which is 1 filial: = complex level state. Please refer to the figure of the second picture speed "to adjust the medical bed recovery level" "also in the case" because the main control unit 10 only needs to switch one motor M331371 to the early switch + only one selection switch As an indication. And the road r2〇早元10 includes a speed control circuit 110 and an angle calculation electric circuit, and the angle between the head block and the horizontal plane of the treatment bed is raised by the angle of the gigantic block, and the speed of the operation is performed. Control circuit Η0. The speed control circuit 11Q is used to control the horse to calculate the electric power...the obtained angle value is two = I set the speed of operation. The replacement order 7110 provides the corresponding control t early and switching unit 3Q. Among them, the driving signals supplied to the driving unit 20 are control signals A, B, C, and D.

The transistor is turned on simultaneously with the transistor Q4, and i: Q2 is turned on simultaneously with the transistor Q3. Only ^, the body is set as the first terminal and the second terminal, :: factory = quasi-motor (four) is positively actuated; when the first terminal connection device will exhibit reverse operation and the child receives positive voltage level, the motor M331371 ^'Although the medical level of the head block is raised (4), the main (4) unit 1 () will turn on the control signal B and the transistor Q3 according to the corresponding control command. . The electro-optical daily peptide Q2 r st is turned on after the transistor is turned on, and no abnormal negative voltage level is supplied to the first terminal of the motor device, and the positive voltage level criterion of the transistor end after the conduction is passed through the switching unit 3 〇哭 = f and: a group of the first 'winding I; of the second terminal of the motor device. As a result, the motor receiving the reverse power is charged to restore the medical bed to a horizontal state. P is true and vice versa. When the user wants to raise the medical department block that is in the horizontal state, as long as the corresponding control unit is input, the fish master control unit 1G will follow the control finger. ^ A and D, the transistor and the transistor are turned on. 唬 At this time, the switching of the selection switch of the positive cell 3Q of the source terminal of the transistor Q1 after the conduction is supplied to the motor device Q4 There is no extreme negative power, the second winding of the second terminal. So, the motor unit that receives the forward power can raise the head block of the bed. Among them, choose to switch 4::,: medical condition To tie a relay. The contents of the case of this case are further explained in the case of -, and ten, please refer to the section: Η ::=: For the patients to carry out the disease. The medical bed raised by the upper beam is restored to a horizontal state, and the method of operating the bed is used. Among them, the third picture is the method of controlling the speed of the operation of the medical bed according to the content of the Zhaji. In the example of the 10 M331371 bed, the user must press a special button set on the external controller of the medical disease. To further enable the doctor:: = to: the state of the song or tilt to return to the horizontal state, such as the corresponding control command provided by the step single V button, the main switch and one. to the switch unit a drive unit; The selection switch will connect one of the output terminals of the n-circuit to the second winding of the second terminal of the motor single signal according to the control signal.

The method of speed method is used to control the operation of the medical bed. First, the user must also press Placed under the medical bed or on the 12 M331371 external controller The special button causes the main control: command to receive the special button: 匕: read the switch 30 and the drive unit 2〇, as in step (10). The drive number ^ select switch will be based on this The control signal is such that the second=== of the second terminal is further phase=::, and the reverse power is supplied to the selection switcher, and the switching path provided by the device is supplied to the horse speed action, the second... , ^ S420 causes the head block of the reading bed to drop rapidly, as in step # ^ i ^ ^ lfL ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ # ϋ 120, the angle calculation circuit 12 obtains the angle calculation The state of the motor in front of the circuit is also used to calculate the angle between the eye and the horizontal plane to determine the current position i of the head block of the bed, as in step s 4 (4). When the main control unit 1() sums up the result of the feedback signal returned by the motor device, "Say 2 = whether the position of the block of the wide gauge block has been a, jin, and the head block and the horizontal plane of the sputum treatment bed The angle between the horizontal planes, that is, the head area S440. Whether it is lower than a preset value, If the main control unit 1 〇 determines that the value is still greater than the preset value, the calculation result of the medical circuit 120 is that the 13 M331371 position of the smashed bed of the squat bed is not yet close to the horizontal plane. Therefore, the speed of the main control unit ig The circuit 11〇 controls the motor device to continue to decrease the saturation velocity value. #Main control unit W judges the calculation circuit of the angle calculation circuit 12〇. The second indicates that the head block of the medical bed is currently under; The crime is close to the horizontal plane. Therefore, the speed control of the main control unit ι〇 provides the corresponding control signal to control the selection cut: the switch is switched back to the first winding of the second terminal of the motor device, so that the medical unit block The speed of the drop returns to normal, that is, the equal speed drops to achieve the purpose of the flush, as in step S45. Finally, when the head of the medical bed has fallen to the bed surface of the water medical bed, it is only half-active, such as step S460, when the water is finished, the end of the motor device is treated. The advantage is that the electronic control method is used to control the speed of the segment to operate, so that in the special case, the fast ball changes: the beds of the shape L can be buffered. In this way, the situation is fast and comfortable: lying = changing from a bow or tilt state to a horizontal state on the bed. The other point that is provided is that the main control unit of the L-bed is returned by the motor unit (4), and the state is based on the calculated state of the knot ==. The speed of the completion of the Lima built 1 set is the advantage provided by the case - the "motor" has two different winding characteristics, when the user's control unit will be under the current dream, the main The first winding of one end of the motor garment is switched to the 14th M331371 second burning group, which speeds up the state of the medical bed.
