[0068] see figure 1 , which is a schematic diagram of the patient bed positioning device provided in this embodiment.
[0069] The patient bed positioning device provided in this embodiment includes: a control board 100 , a bed control box 200 and a motor 300 .
[0070] The control board 100 includes a knob 110 , a knob encoder 120 and a microprocessor 130 .
[0071] The doctor can control the movement of the patient bed by rotating the knob 110, which can be rotated clockwise or counterclockwise. The rotation direction of the knob 110 corresponds to the movement direction of the patient bed, for example, the clockwise rotation of the knob 110 corresponds to the patient bed going in, and the counterclockwise rotation of the knob 110 corresponds to the patient bed getting out of bed.
[0072] Different rotation angles of the knob 110 correspond to different numbers of pulses output by the knob encoder 120 . For example, when the rotation angle of the knob 110 is 90°, the num...

[0091] It should be noted that there may be some burrs in the pulses sent by the rotary encoder 120 received by the microprocessor 130. In some cases, for example, the burrs have a relatively wide width, and these burrs may be mistaken for pulse signals, so that The number of pulses obtained by the microprocessor 130 is not accurate. Further, the number of pulses after frequency multiplication is also inaccurate. Therefore, before the number of pulses is multiplied, the microprocessor 130 may also perform digital filtering on the pulses to remove burrs in the pulses.
[0092] It should be noted that when the knob 110 is rotated, the pulses output by the rotary encoder 120 include two pulses, which are A pulses and B pulses.
[0093] see figure 2 , which is a schematic diagram of the principle of the rotary encoder 120 provided in this embodiment.
[0094] Wherein, the pulse of channel A is the pulse output from node A, and the pulse of channel B is the pulse output from nod...

[0125] The patient bed positioning device provided in this embodiment further includes buttons on the control panel 100, and the rotary encoder 120 includes buttons, and the buttons correspond to the buttons.
[0126] When the button is pressed, the key of the rotary encoder 120 is triggered to send a press signal to the microprocessor 130 .
[0127] It should be noted that when the knob 110 is rotated, the rotary encoder 120 continuously outputs pulses to the outside. When the button is pressed, the key of the rotary encoder 120 is triggered and sends a pressing signal to the microprocessor 130. The pressing signal is used to prompt the microprocessor 130 to process the currently received pulses to obtain the number of pulses.
[0128] see Figure 4 , which is a schematic diagram of the principle of generating a press signal provided by this embodiment.
[0129] Figure 4 Among them, the node S is the output node corresponding to the pressing signal. The principle of gener...
