AI Technical Summary
In existing technologies, overload detection methods for safety switches are difficult to improve the detection accuracy of analog output parameters without increasing hardware costs and computational burden, leading to misjudgments or missed overload detections.
By acquiring the output detection value of the safety output terminal and the preset calibration feature point set, the target calibration interval is determined, and the calibration output parameter value is calculated based on the piecewise linear calibration method. The overload state is then determined in conjunction with the target output state.
It improves the accuracy and reliability of overload detection of safety switches, reduces the impact of sampling link nonlinearity and device errors, and is suitable for cost-sensitive and real-time-critical applications.
