[0086] In yet another specific embodiment of the present disclosure, referring to FIG. 9, the control circuit 612 further includes a noise filtering circuit 6122 configured to filter noise in an analog pressure status value sent by a pressure sensor 6111, and send the noise-filtered analog pressure status value to the analog-digital conversion circuit 6121.

[0087] In the present disclosure, the noise filtering circuit 6122 performs noise filtering on the analog pressure status value sent by the pressure sensor 6111, avoiding inaccurate signal detection caused by noise interference in the analog signal, and improving signal accuracy.

[0088] In yet another specific embodiment of the present disclosure, the pressure sensor 6111 includes a plurality of sub-pressure sensors, which are set on the same protection panel for mutual sensing and verification, or the plurality of sub-pressure sensors are respectively set at contact positions of different protection panels and the status control mechanism of the protection panels to sense the status information of the different protection panels.

[0089] Specifically, the display mechanism 62 includes: an LED indicator light and a display screen.

[0090] The present disclosure displays the status information of the protection panel 11 through the LED indicator and/or the display screen, which can provide medical personnel with an intuitive display effect and is easy to install and maintain.

[0091] The LED indicator light and/or the display screen receives the status information sent by the plurality of sub-pressure sensors, and performs different displays based on the status information.

[0092] For example, the LED indicator light may indicate the working status of the protection panel in different colors. For example, when the protection panel is in the working status, the LED indicator light may display green, and when the protection panel is in the lay-down position, the LED indicator light may display red. The LED indicator light may also indicate the working status of the protection panel in a display method. For example, when the protection panel is in the working status, the LED indicator light may be in stable display, and when the protection panel is in the lay-down position, the LED indicator light may be flashing display.

[0093] Therefore, the present disclosure may set a plurality of sub-pressure sensors for the same protection panel to verify mutual sensing. The present disclosure may also display differently for different protection panels, and display the status information of the different protection panels through the display mechanism, avoiding inconvenience in use caused by the need for medical personnel to comprehensively observe the radiotherapy treatment couch, and further improving use experience of the radiotherapy treatment couch.
