Abstract: A target device receives a plurality of pieces of first data, where each piece of the plurality of pieces of first data includes first ephemeris information and/or first almanac information. The target device identifies abnormal first data among the plurality of pieces of first data, where the plurality of pieces of first data include the abnormal first data, and the plurality of pieces of first data are obtained by the target device from a plurality of access network devices. A plurality of pieces of first ephemeris information and/or a plurality of pieces of first almanac information in the plurality of pieces of first data correspond to a first satellite. The target device may determine, by using the plurality of pieces of first ephemeris information and/or the plurality of pieces of first almanac information, that a piece of first ephemeris information and/or a piece of first almanac information is abnormal.

Abstract: An enclosing wallboard firm-connection device includes an enclosing wall, a column body and a door. The column body is mounted on the enclosing wall, the door is mounted on the column body.
