Problems solved by technology
The advantage of this is that the principle is simple, but the amount of parameters is quite large, and the angle of each action needs to be tested in practice. It seems simple but actually requires a lot of work.
And the flexibility of control is poor, because the gears are limited

The invention relates to a surgical bed tabletop automatic control system and method. When receiving a control signal, a controller reads a tabletop inclination angle value theta1, a backplane bendingangle value theta2 and a tabletop height value H1; when the control signal is a signal for tabletop back-tilt control and / or backplane down-fold control, it is determined whether theta1, theta2 and H1 satisfy a condition 1, and when the condition 1 is satisfied, control is performed to perform a tabletop back-tilt operation and / or to perform a backplane down-fold operation; when the control signal is a signal for tabletop back-tilt control and backplane up-fold control, it is determined whether theta2 is smaller than theta1, when theta2 is smaller than theta1, it is determined whether theta1,theta2 and H1 satisfy a condition 2, and when the condition 2 is satisfied, a tabletop back-tilt operation and a backplane up-fold operation are performed; when the control signal is a signal for tabletop front-tilt control and backplane down-fold control, it is determined whether theta2 is greater than theta1, when theta2 is greater than theta1, it is determined whether theta1, theta2 and H1 satisfy a condition 3, when the condition 3 is satisfied, control is performed to perform a tabletop front-tilt operation and to perform a backplane down-fold operation, and when the condition 3 is not satisfied, operation is stopped.
Description
technical field [0001] The invention relates to the technical field of operating table tops, in particular to an automatic control system and method for operating table tops. Background technique [0002] When designing the operating bed, it is necessary to specify the limit angles of each action, for example: the maximum left-right tilt angle of the table top is 25 degrees, the maximum front-back tilt angle of the table top is 30 degrees, the maximum back panel folding angle is 70 degrees, and the back panel folding down maximum angle The angle is 40 degrees, etc. At the same time, the maximum angle that these actions can achieve is also limited by the height of the table. Only when the table is higher than the ground can the realization of the limit angle be guaranteed. When the table top is low, some actions cannot reach the limit angle, such as the back panel folding down and the table top tilting backward. If the action angle is too large, the head board will touch the...
