Pile foundation perpendicularity deviation monitoring device and method based on standard time synchronization

The invention discloses a pile foundation perpendicularity offset monitoring device and method based on standard time synchronization. A vehicle-mounted control system is used for collecting working data of a drilling machine on the ground, and a wireless intelligent collecting and monitoring device is used for collecting real-time azimuth data of a drilling bucket in a drill hole; determining the data acquired by the two in the same time period through the synchronous recording time; when the drilling bucket takes soil to the ground for a short time, data collected by the wireless intelligent collecting and monitoring device is sent to the vehicle-mounted control system through wireless communication; the vehicle-mounted control system combines drilling machine and drilling bucket data obtained in the same time period to obtain the drilling track of the drilling bucket in the time period, the track is compared with a preset track, if the track exceeds a threshold value, an alarm prompt is given, and drilling
