Technical Field

[0001] The utility model relates to the technical field of measurement sensors, in particular to an embedded intelligent warning device based on GNSS displacement monitoring. Background Art

[0002] A GNSS receiver is used for long-term online monitoring of the displacement of the ground surface. After the device is installed, it will not be manually moved. When there is a slight displacement on the ground surface, the data monitored by the GNSS device will also change, so as to monitor the displacement of the ground surface. The GNSS receiver is suitable for fields such as mine surface subsidence and slope monitoring with a large range, many monitoring points, and low observation frequency, landslide and earth-rock dam displacement monitoring, etc.

[0003] At present, most GNSS receivers in China mainly refer to devices that track satellites, receive satellite data and transmit the received satellite data to the upper computer. GNSS receivers usually do not include the necessary receiving antenna and antenna cover for GNSS protection. These three parts exist independently. When installing the monitoring point, the GNSS receiver needs to be placed in the monitoring main box and connected to the GNSS satellite receiving antenna through a feeder line. Moreover, the satellite receiving antenna is protected by a fiberglass antenna cover. Usually, the installation schematic diagram of the monitoring point is as Figure 1 , and the connection of the devices in the monitoring main box is as Figure 2 .

[0004] Under the existing technology, in addition to configuring a receiving antenna and an antenna cover for the GNSS receiver, it is also necessary to configure a support and protection device to reduce the failure of electronic products caused by various corrosions and protect sensitive electronic components.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides an embedded intelligent early warning device based on GNSS displacement monitoring, and has the following beneficial effects:

[0018] 1. The embedded intelligent early warning device based on GNSS displacement monitoring greatly improves the device's protection ability through integrated design.

The power supply and debugging interfaces are waterproof designed. The device reaches the IP protection level, is more suitable for long-term use in the wild, and can be used without protection or with low protection. By installing a waterproof breathable valve, the device's performance is improved. Installing the waterproof breathable valve can greatly reduce fogging and condensation inside the housing, reduce electronic product failures caused by various corrosions, protect sensitive electronic components, and the high air permeability can balance the housing pressure, enabling better heat dissipation and decompression effects inside the housing.

[0019] 2.

The machined housing has the GNSS antenna signal receiving plane higher than the horizontal plane of the aluminum alloy lower housing. Signals reflected by surrounding ground objects below the horizontal plane of the aluminum alloy lower housing can all be reflected off (blocked), greatly reducing the errors caused by multipath signals, effectively eliminating the multipath effect, and further improving the monitoring accuracy.

[0021] 4. The embedded intelligent early warning device based on GNSS displacement monitoring can meet the usage requirements of different scenarios because it has both 4G GSM communication and WIFI wireless communication methods.

[0022] 5. By installing a variable neck adapter, the device based on GNSS displacement monitoring can have multiple quick installation methods. The variable neck adapter has installation screw holes and can be connected to different carriers for installation to adapt to different installation environments.

[0023] 6. The embedded intelligent early warning device based on GNSS displacement monitoring is more suitable for industries with limited installation conditions, such as reservoir dams, bridges, construction sites, etc., because it is convenient and fast to install, easy to select points, easy to construct, and easy to monitor.

[0024] 7. The embedded intelligent early warning device based on GNSS displacement monitoring also integrates a temperature and humidity sensor, which can provide the user with the temperature and humidity values at the installation point at the same time, facilitating the user to master the environmental conditions at the installation site and further study the correlation between settlement data and environmental data.
