Abstract: Provided is a precise fault location method for a collector line in an onshore wind farm. The method includes sends sending, by a slave unit, a high-voltage pulse signal at the beginning of a collector line to measure a cable length at a fault point of the collector line. A master unit and the slave unit send high-voltage pulse signals to each other to measure a cable length at any point on the collector line, thereby obtaining a geographical location corresponding to the cable length. The two measured cable lengths are compared and if the measured lengths are inconsistent, the master unit is moved, to make the two measured lengths equal with multiple approaches. In this case, the position of the master unit is a geographical location corresponding to the fault point.

Abstract: There are provided in embodiments of the present disclosure a living body detection method, system and a non-transitory computer-readable recording medium. The living body detection method includes: acquiring device information of a terminal used to acquire an image of an object to be detected; determining a device risk level of the terminal; determining a living body detection strategy based on the device risk level of the terminal. The above technical solution adjusts the living body detection strategy by utilizing the device information of the terminal, which guarantee a true living body to go through a pass of the detection at a smaller cost, and at the same time makes it difficult for a false and malicious living body to go through a pass of the detection, thereby greatly reducing security risk of the living body detection, enhancing the user experience, and preventing the malicious request from occupying the system resources.
