Embodiment 2

[0048] This embodiment is used to detect the timeliness of the positioning solution of the Beidou monitoring pile.

[0049] Test equipment and tools: two sets of high-precision Beidou monitoring piles with integrated electronic gyroscopes, GNSS measuring antennas, and tripod measuring instruments. (Note: In order to better simulate the deformation of the foundation pit during actual use, this embodiment does not fix components such as GNSS receivers and DTUs on the detection pile, and uses a power box instead of a photovoltaic power supply system to supply power to the corresponding equipment.)

[0050] The specific test process is as follows:

[0051] (1) Two GNSS receivers connected with DTU are placed in the power box and connected to the power supply; one of the two GNSS measurement antennas is used as a base station antenna, placed on the detection pier and fixed; the other GNSS measurement antenna Placed on a tripod surveyor as a rover antenna.

[0052](2) Both differe...

Embodiment 3

[0064] This embodiment is used to detect the monitoring accuracy of Beidou monitoring piles.

[0065] Test equipment and tools: two sets of integrated electronic gyroscope high-precision Beidou monitoring pile equipment (one set as a base station and the other set as a rover), tripod measuring instrument.

[0066] Note: In order to better simulate the deformation of the foundation pit during actual use, this embodiment does not fix components such as GNSS receiver and DTU on the detection pile, and uses a power box instead of a photovoltaic power supply system to supply power to the corresponding equipment.

[0067] The specific test process is as follows:

[0068] (1) Two GNSS receivers connected with DTU are placed in the power box and connected to the power supply; one of the two GNSS measurement antennas is used as a reference value antenna, placed on the detection pier and fixed; the other GNSS measurement antenna Placed on a tripod surveyor as a rover antenna, the rover...

Abstract

The invention provides a high-precision BeiDou monitoring pile with an electronic gyroscope integrated. The high-precision BeiDou monitoring pile comprises a monitoring pile body, a DTU and a GNSS receiving machine, a GNSS measuring antenna fixed to the top of the monitoring pile body and a photovoltaic power supplying system fixed to the monitoring pile body, wherein the DTU and the GNSS receiving machine are installed in the monitoring pile body. The DTU is connected with a COM interface of the GNSS receiving machine through a serial port line; the GNSS measuring antenna is connected with anANT interface of the GNSS receiving machine through an antenna connecting line; the photovoltaic power supplying system is connected with the DTU and the GNSS receiving machine through a power line correspondingly to supply power for equipment. An electronic gyroscope, a GNSS board card and an MCU are integrated on a PCB main board of the GNSS receiving machine to improve the positioning precision and the timeliness of the BeiDou monitoring pile. According to the high-precision BeiDou monitoring pile with the electronic gyroscope integrated, the GNSS measuring antenna receives BeiDou navigation satellite signals, and the signals are transmitted to the mainboard of the GNSS receiving machine to be decoded; the GNSS receiving machine uses satellite data received by the DTU and real-time information of the electronic gyroscope and sends the satellite data and the real-time information to a server synchronously, and real-time auxiliary correction of a GNSS resolving result is realized, sothat high-precision monitoring is achieved.

Description

technical field [0001] The invention relates to the technical field of foundation pit monitoring, in particular to a high-precision Beidou monitoring pile with an integrated electronic gyroscope. Background technique [0002] With the development of the natural environment by humans, various sudden geological disasters, such as mountain torrents and mudslides, have an increasing impact on people. Some roads, bridges and tunnels built in mountainous areas, once damaged by geological disasters, This in turn leads to interruption of traffic and has a serious impact on emergency repairs and other work. Therefore, how to do a good job of early warning for possible address disasters has become an urgent problem to be solved. In the prior art, geological changes are usually detected through satellite remote sensing technology or aircraft aerial photography, and subtle changes in the geological environment cannot be found, which affects the timeliness of monitoring the geological e...
