2 results about "Threshold crossing" patented technology

This disclosure relates to the field of intelligent robot technology, and more particularly to a threshold-crossing method and a mobile robot. The method includes: controlling the mobile robot to move along a preset route; determining a target threshold based on map information of the mobile robot's current location; or, determining the target threshold based on environmental information along the mobile robot's current route; and adjusting the mobile robot's obstacle-crossing actions to the target threshold so that the mobile robot can cross the target threshold. This disclosure utilizes zoning information or environmental information to determine the target threshold, and adjusts the corresponding obstacle-crossing actions according to the actual situation of the target threshold, avoiding repeated trial actions that lead to low task execution efficiency or damage to the robot body, thereby improving the success rate of threshold crossing.

This invention relates to the field of circuit board monitoring and fault diagnosis technology, and discloses a circuit board fault prediction method and system. The method includes collecting voltage and current signal data of the circuit board during operation, extracting time-series features to obtain a dynamic state change sequence; inputting the dynamic state change sequence into a preset support vector machine to obtain a state evolution trajectory, calculating the time point when the evolution rate changes abruptly, as the starting point of instability; calculating the amplitude intensity value of the starting point and judging the stability qualitative change trend; if a stability qualitative change trend exists, performing spectral decomposition on heterogeneous data sources to obtain a risk score for overall system instability; extracting state fluctuation features based on the risk score to determine the system safety boundary; if the state evolution sequence exceeds the system safety boundary, a potential threshold crossing occurs, generating a warning signal; extracting subtle feature sequences based on the warning signal to obtain the final stability assessment. This method can achieve accurate prediction of circuit board faults.
