A real-time landslide monitoring Beidou receiver and its working method

Abstract

The invention discloses a Beidou receiver of real time landslide monitoring type and a working method of the Beidou receiver. The receiver is composed of a receiver antenna unit, a receiver host unit and a power source. The receiver host unit includes an inner circuit and a control panel. The inner circuit includes a BDS positioning module, a serial port to USB module, a switch control module, an indication lamp module, a GPRS wireless control module and a power supply module. The control panel is composed of a USB interface, a configuration switch, an indication lamp, a GPRS antenna interface, a power interface and a receiver antenna interface. The receiver antenna interface transmits satellite signals received by the receiver antenna unit to the inner circuit for processing and then transmits processed original observation data to a service terminal through the GPRS wireless control module for related positioning and calculating. The receiver provided by the invention is small in size and simple in operation and can be arranged on a landslide mass in a large scale and collect data in real time. Therefore, rich and effective displacement data observation values are provided for landslide monitoring early warning.

Description

technical field [0001] The invention relates to the technical field of Beidou navigation systems, in particular to a real-time landslide monitoring Beidou receiver. Background technique [0002] The GNSS (Global Navigation Satellite System) global satellite navigation system and the components of the GNSS receiver can be divided into three parts: the receiver antenna unit, the receiver host unit and the power supply. The main function of the antenna unit is to convert the weak electromagnetic wave of the GNSS satellite signal into a current, and process the signal through the amplifier, frequency converter and band-pass filter; and the main function of the receiver unit is to track the signal transmitted by the antenna , processing and measurement. [0003] The surveying GNSS receivers currently on the market have the following disadvantages for landslide monitoring: first, they do not support wireless network communication for wireless transmission of their observation dat...

Problems solved by technology

[0003] The surveying GNSS receivers currently on the market have the following disadvantages for landslide monitoring: first, they do not support wireless network communication for wireless transmission of their observation data; Operation (For example, Leica GRX 1200 Pro receiver supports network parameter configuration function, but it can only use wired network, especially for landslides and other disasters that cannot be connected to wired network, the combination of GPRS wireless network communication and GNSS receiver is effective solve this problem); third, most of the functions contained in the receivers on the market are redundant for real-time landslide monitoring, which causes a waste of resources; fourth, there is no real-time GNSS only for landslide monitoring on the market The receiver, with simple functions, is only responsible for transmitting the original data to the server, and the client is only responsible for data collection, so the cost is reduced in both hardware and software, and hardware losses caused by landslides are reduced
