Title:
電動ベッド
Document Type and Number:
Japanese Patent JP6905255
Kind Code:
B2
Abstract:
To provide an electric bed that has achieved less expensive and highly accurate feedback control, and is capable of executing interlocking control for a back angle and a knee angle with improved usability.SOLUTION: An electric bed 1 includes an operation signal control unit 50 for executing interlocking control of a movable part of a landing part 18 involved in adjustment of a back angle and a knee angle. The operation signal control unit 50 includes a storage part 504 for storing a plurality of interlocking control points on a coordinate plane of the back angle and the knee angle involved in the interlocking control, an interlocking control setting value calculation part 506 for calculating a control line subjected to curve approximation based on the interlocking control points with a start reference point indicating coordinate points of the back angle and the knee angle on the basis of a sensor signal from a sensor for detecting a motion of the movable part involved in a motion of the landing part 18, and calculating a setting value for executing the interlocking control toward an actual target point calculated and set on the control line, and an FB control part 30 for executing feedback control toward the actual target point according to the control line based on the setting value.SELECTED DRAWING: Figure 4
