Title:
CONTROL DEVICE, ELEVATOR SYSTEM, AND INFORMATION PROCESSING DEVICE
Document Type and Number:
Japanese Patent JP2020117320
Kind Code:
A
Abstract:
To provide an elevator system capable of detecting an accurate load detection value without a lot of work even when the load detection value of a car shows abnormal.SOLUTION: A control device 10 comprises a linear approximation calculating part 17, an abnormality diagnosis part 18 at a balanced car, and a bias-value/gain-value adjustment part 21, where the linear approximation calculating part calculates a linear approximation expression of a torque command value corresponding to a load detection value based on data series of the torque command value recorded in a torque command value recording part 16 for each load detection value detected by a car internal load detection part 12, the abnormality diagnosis part at a balanced car diagnoses the load detection value as abnormal when the load detection value calculated by the linear approximation expression in the balanced state between the car in a specified section and the torque deviates from a specified value, and the bias value/gain value adjustment part adjusts a bias value and a gain value to use for detecting the load detection value from an output value of a load sensor by the car internal load detection part 12 when the load detection value is diagnosed as abnormal.SELECTED DRAWING: Figure 1
