Real-time monitoring method of inclination angle of operating bed tabletop

Abstract

The invention provides a real-time monitoring method of an inclination angle of an operating bed tabletop. The method comprises the steps: employing a single-chip microcomputer to simulate an SPI busfor communication with an inclination angle sensor through an I / O port, transmitting a command, and reading inclination angle data of the operating bed tabletop; sending a command to receive 11-bit binary data related to the angle, selecting to collect the angle data for multiple times, and then reducing errors through an averaging method; and finally, converting the 11-bit binary data into the angle through a conversion formula. By means of the method, the inclination angle of the operating bed tabletop can be monitored in real time, and therefore functions of one-key type body position adjustment, one-key reset, real-time memory and the like of an operating table are achieved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a real-time monitoring method for a high inclination angle of an operating bed table. Background technique [0002] Doctors need to have different posture adjustments when performing different operations, so the operating table needs to have corresponding movements to cooperate with the operation. For example: the operating bed leans left, right, forward, backward, the backboard rises, and the backboard falls. In order to achieve the purpose of real-time monitoring, the tilting state of the operating bed must be known in real time. The more common method now is to use two methods of rotary variable potentiometer and tilt sensor. [0003] The principle of rotating the variable potentiometer is: when the bed moves to different positions, it will inevitably drive the adjustment axis of the variable resistor to rotate, so that the resistance connected to the c...

Problems solved by technology

However, the accuracy of the rotary potentiometer is not easy to control. In addition, initial debugging must be carried out before leaving the factory to determine the resistance of the horizontal position and the resistance of the maximum rotation angle, so that the calculation can be accurate; the principle of the tilt sensor is to use the tilt sensor and the operating bed The table moves together and reads the inclination angle of the tilt sensor synchronously to obtain the inclination angle of the table top of the operating table, but the accuracy generally obtained is not very high now
