One-machine and multi-antenna GNSS displacement monitoring system and method

Abstract

The present invention relates to a one-machine and multi-antenna GNSS displacement monitoring system. The system comprises a multi-antenna system, a monitoring host and a monitoring background; the multi-antenna system comprises a reference antenna, a plurality of monitoring antennas and a multi-antenna switching control module; the reference antenna and the multi-antenna switching control moduleare in wired connection with the monitoring host, the monitoring antennas are in wired connection with the multi-antenna switching control module; the monitoring host comprises a data receiving processing module, a signal transmission module and a power supply module, the data receiving processing module is configured to process position data of the reference antenna and the monitoring antennas, and the signal transmission module is configured to transmit the position data of the reference antenna and the monitoring antennas to the monitoring background; and the monitoring antennas are in wireless communication connection with the monitoring background. The monitoring system is employed in the displacement monitoring with dense monitoring points to greatly reduce the monitoring and later maintenance operation, the monitoring points only need one hardware device to achieve effective monitoring, reduce the monitoring cost and improve the stability of the monitoring device.

Description

technical field [0001] The present invention relates to the technical field of satellite positioning and monitoring, more specifically, to a multi-point displacement with multi-antenna in one machine, which can realize multi-point precise positioning by using the global navigation satellite system, so as to monitor the displacement of multiple known points for a long time Monitoring systems and monitoring methods. Background technique [0002] With the wide application and promotion of GPS, GLONASS, Beidou and other satellite positioning systems in surveying, navigation, communication and many other fields, the development of technology has gradually matured, and good development has also been achieved in the field of satellite positioning and monitoring, especially in geotechnical engineering. monitoring has been widely used. [0003] In the existing satellite positioning monitoring system, the positioning antenna is connected one-to-one with the monitoring host, and each ...

AI Technical Summary

Problems solved by technology

[0005] 1. In the traditional monitoring method, each monitoring point requires independent hardware, power supply, communication, and construction. The monitoring cost is too high, and each monitoring station needs to be maintained separately in the later stage, and the stability of the equipment is difficult to guarantee.

[0006] 2. Traditional monitoring methods only use reference stations for positioning assistance, and the monitoring accuracy is not stable enough

[0007] 3. In order to improve the monitoring accuracy, the traditional monitoring method needs to obtain a large amount of monitoring data, which leads to excessive pressure on the power supply and communication system, and has high requirements for data calculation methods
