DETAILED DESCRIPTION

[0029] The technical solutions in the present application will be clearly and completely described below in conjunction with the drawings in the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0030] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0031] At present, most of the mainstream GNSS monitoring equipment on the market adopts back-end solution, which has high requirements for servers and communication networks. Especially in some remote mountain environments, server solution will consume more resources and is not conducive to later maintenance. Therefore, there is an urgent need for a GNSS receiver terminal that reduces the complexity of server solution and installation and maintenance costs.

[0032] Please refer to Figures 1 to 5 In the first aspect, the present application provides a GNSS receiver terminal, and the technical solution is as follows:

[0033] The GNSS receiver terminal 1 includes a host 2 and a power supply system 3. The power supply system 3 is detachably mounted on the host 2 and is used to supply power for the operation of the host 2.

[0034] The host 2 at least includes a communication module 21, and a full-network high-precision antenna 22, a positioning module 23, and a controller 24 respectively connected to the communication module 21, and the positioning module 23 is also connected to the full-network high-precision antenna 22;

[0035] The full-network high-precision antenna 22 is used to receive satellite signals and transmit the satellite signals to the positioning module 23 for processing to obtain the original satellite observations; the communication module 21 is used to receive the original satellite observations and calculate the position information on the host 2 end; the controller 24 is used to control the operation of each module in the host 2.

[0036] Among them, in actual applications, the technology used by the GNSS receiver terminal 1 to receive satellite signals and solve the position information is RTK technology. RTK technology represents real-time dynamic relative positioning information. Simply put, the satellite data observed by the GNSS receiver terminal 1 located at the base station is sent out in real time through the data communication link (radio station), and the mobile station GNSS receiver terminal 1 located nearby receives the radio signal from the base station GNSS receiver terminal 1 while observing the satellite. The mobile station GNSS receiver terminal 1 processes the received signal in real time to give the three-dimensional coordinates of the mobile station, which represents the position information and estimates its accuracy. RTK technology can obtain centimeter-level positioning accuracy in a very short time, and is widely used in the fields of map control measurement, construction layout, engineering measurement and topographic measurement.

[0037] Among them, in the prior art, when installing the receiver equipment at the monitoring point, it is necessary to install the receiver body, the antenna, the solar panel and the underground battery. The solar panel and the underground battery are used to power the receiver body. The installation steps are extremely complicated and will consume a lot of manpower and material resources, which is not conducive to subsequent maintenance. In order to solve the above problems, the GNSS receiver terminal 1 includes a host 2 and a power supply system 3 detachably connected to the host 2. The power supply system 3 is used to power the host 2. There is no need for an underground battery, which improves the convenience of disassembly and assembly of the GNSS receiver terminal 1 and saves labor costs.

[0038] Among them, in actual application, the host 2 is provided with a communication module 21, which is the core module of the GNSS receiver terminal 1 and is used to solve the original satellite observation quantity, wherein the original satellite observation quantity at least includes pseudorange observation quantity, carrier limit observation quantity, Doppler shift observation quantity, and signal attenuation observation quantity. The communication module 21 is usually provided with a communication interface, such as a network port, a serial port, and a USB interface for connecting with other modules. The communication module 21 is at least connected to a full-network high-precision antenna 22 through the communication interface, wherein the full-network high-precision antenna 22 is used to receive satellite signals and is equipped with a low-noise amplifier circuit, which can achieve high-precision positioning, and can connect different satellite positioning with the GNSS receiver terminal 1, thereby improving the compatibility of the GNSS receiver terminal 1. The full-network high-precision antenna 22 transmits the received satellite signal to the positioning module 23. The positioning module 23 decodes the satellite signal to obtain the original satellite observation, and then sends the original satellite observation to the communication module 21 for local solution to obtain location information, so as to avoid all the original satellite observations being transmitted to the back-end server, causing the server to consume too many resources. Among them, after the communication module 21 selects local solution, the communication module 21 will directly solve the original satellite observation. The specific solution process includes: analyzing the Kalman filter, median, mean and other filtering algorithms to adapt to the deformation monitoring of the GNSS receiver terminal 1 in different scenarios, and then further filtering and denoising the real-time solution results of the original satellite observations, so that the GNSS receiver terminal 1 can meet the requirements of universal deformation monitoring and improve the real-time monitoring. After the communication module 21 selects the server solution, the original satellite observation will be transmitted to the back-end server for solution through the positioning module 23 and the full-network high-precision antenna 22.

[0039] Among them, in actual applications, after the communication module 21 completes the calculation and obtains the position information, the communication module 21 can upload the position information to the platform through the positioning module 23 and the high-precision antenna 22 of the entire network to ensure the timeliness and accuracy of the positioning of the GNSS receiver terminal 1.

[0040] Among them, in actual applications, the controller 24 is used to control the coordinated operation of each module in the host 2 to ensure that the host 2 realizes the local solution function.

[0041] Furthermore, the host 2 also includes a program upgrade module 26 , which is connected to the communication module 21 and is used to remotely upgrade the communication module 21 .

[0042] Among them, in actual application, the host 2 also includes a program upgrade module 26. Specifically, the program upgrade module 26 is built into the host 2 and connected to the communication module 21. In the prior art, a USB interface is usually set on the communication module 21. When the GNSS receiver terminal 1 needs to be upgraded, the data line is connected to the background server through the USB interface for upgrading. This method is relatively complicated and consumes a lot of human resources. Therefore, this application adopts a built-in program upgrade module 26 to remotely upgrade the communication module 21 through the menu interface of the GNSS receiver terminal 1, simplifying the upgrade operation and reducing labor costs. And by updating the communication module 21 in real time through the program upgrade module 26, the flexibility of the GNSS receiver terminal 1 to adapt to different environments can be improved.

[0043] Furthermore, the host 2 also includes a storage module 27, which is connected to the communication module 21 and is used to store the position information obtained by the communication module 21 by solving the original satellite observation quantity.

[0045] Furthermore, the host 2 also includes a power module 28 , which is connected to the communication module 21 and is used to supply various voltages required by the host 2 .

[0046] In actual application, by setting the power module 28 to connect the communication module 21, the host 2 is powered for independent operation, ensuring that the host 2 can be used alone, thereby improving the flexibility of the GNSS receiver terminal 1 and saving manpower and material costs.

[0047] Furthermore, the power module 28 is configured as a lithium battery that is automatically charged by solar energy.

[0048] Among them, in actual application, the power module 28 is a built-in module connected to the communication module 21, and can be set as a lithium battery automatically charged by solar energy.

[0051] Furthermore, the host 2 also includes a wireless configuration module 30 and a self-organizing network module 25.

[0052] In actual application, the host 2 also includes a wireless configuration module 30, which is connected to the communication module 21 and is used to install wireless devices on the host 2, ensuring that the user can connect to the host 2 through the mobile phone APP and view the configuration information of the host 2, which is convenient for production and field staff to maintain the host 2.

[0053] Furthermore, the host 2 also includes a connection structure 31 , which is disposed at the bottom of the host 2 and is detachably connected to the power supply system 3 .

[0054] Please refer to Figures 3 to 5 In actual applications, the host 2 also includes a connection structure 31, which is arranged at the bottom of the host 2 and is detachably connected to the power supply system 3. The connection structure 31 can adopt a mortise and tenon structure, a snap-on structure, and a keyway structure to achieve a detachable connection with the power supply system 3.

[0055] Furthermore, the connection structure 31 is provided with a first threaded hole 32 , and a screw passes through the power supply system 3 and the first threaded hole 32 , so that the power supply system 3 is detachably connected to the host 2 .
