Abstract: A positioning tag replacement method and a positioning server to implement replacement between positioning tags, where the method includes obtaining, by a positioning server, a moving trajectory of a first positioning tag and a moving trajectory of a second positioning tag, where the first positioning tag corresponds to a first positioned object, and the second positioning tag has no corresponding positioned object, and setting, by the positioning server, the second positioning tag to correspond to the first positioned object when the positioning server determines that the moving trajectory of the first positioning tag and the moving trajectory of the second positioning tag meet a preset condition. The method features low costs, simple and convenient operations, and easy implementation, and avoids that in an operation process, a positioned object escapes being monitored in a positioning system.

Abstract: A rectifier and an electrical power facility in which the rectifier is disposed are provided that relate to the field of electromechanical technologies. The rectifier includes a rectifier circuit, a relay, and a controller. The rectifier further includes a detection resistor and a detection circuit, where the detection resistor is connected in series to a winding in the relay, a detection point of the detection circuit is set between the detection resistor and the winding, and an output end of the detection circuit is connected to the controller. When a voltage detected at the detection point of the detection circuit is abnormal, the detection circuit outputs an alarm signal to the controller, and after receiving the alarm signal, the controller stops outputting a driving signal to the driving end of the rectifier circuit.
