HIGH-PRECISION BEIDOU MONITORING PILE INTEGRATED WITH ELECTRONIC GYROSCOPE

摘要

A high-precision Beidou monitoring pile integrated with an electronic gyroscope, comprising a monitoring pile body (1), a DTU (2) and a GNSS receiver (3) mounted inside the monitoring pile body (1), a GNSS measuring antenna (4) fixed to the top of the monitoring pile body (1), and a photovoltaic power supply system (5) fixed to the monitoring pile body (1). The DTU (2) is connected to a COM interface of the GNSS receiver (3) by means of a serial port line (3.3); the GNSS measuring antenna (4) is connected to an ANT interface of the GNSS receiver (3) by means of an antenna connecting line (4.1); the photovoltaic power supply system (5) is separately connected to the DTU (2) and the GNSS receiver (3) by means of a power line (5.4) to supply power for equipment. An electronic gyroscope (3.1), a GNSS board, and an MCU are integrated on a PCB motherboard of the GNSS receiver (3) to improve the positioning precision and the timeliness of the BeiDou monitoring pile. The GNSS measuring antenna (4) receives BeiDou navigation satellite signals, and transmits the signals to the motherboard of the GNSS receiver (3) for decoding; the GNSS receiver (3) sends satellite data received by the DTU (2) and real-time data information of the electronic gyroscope (3.1) simultaneously to a server, thereby implementing real-time auxiliary correction of a GNSS solution result to achieve high-precision monitoring.
