[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0021] The purpose of the present invention is to provide a high-precision deformation integrated detection device, which solves the problems in the prior art that the meteorological station has errors caused by terrain influence during data collection, high daily operation and maintenance costs, and insufficient functional integration degree.

[0022] To make the above objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] As Figure 1 and Figure 2 shown, the present invention provides a high-precision deformation integrated detection device, including: a meteorological acquisition module, a GNSS positioning module, a data storage module, a serial port module, a solar photovoltaic module, and a data detection module disposed in a waterproof chassis;

[0024] The meteorological acquisition module includes a temperature and humidity sensor, a barometric pressure sensor, a wind speed sensor, a wind direction sensor, and a piezoelectric weighing rain gauge; the meteorological acquisition module is connected to the data detection module through the serial port module; the data detection module is also respectively connected to the GNSS positioning module, the data storage module, and the solar photovoltaic module; the meteorological acquisition module is used to collect meteorological data in real time; the GNSS positioning module is used to receive satellite signals and generate positioning data; the data detection module is used to integrate the meteorological data and the positioning data and achieve landslide deformation early warning through a preset edge computing algorithm; the data storage module is used to store the meteorological data and the positioning data; the solar photovoltaic module is used to supply power to the data detection module.

[0025] Specifically, the weather collection module described in this embodiment includes a temperature sensor, a barometric pressure sensor, a humidity sensor, a wind direction sensor, a rainfall sensor, and an anemometer; the data storage module is connected to the data detection module and can be externally connected to a USB flash drive and an SD card; one end of the serial port module is connected to each sensor and the anemometer, and the other end of the serial port module is connected to the data storage module; the solar photovoltaic module is connected to the data detection module; the temperature and humidity sensor uses an industrial general standard interface, which is convenient for accessing other devices and systems, and is used to monitor the temperature and humidity status near this detection device. A relatively high-precision sensing core and related devices are used inside the temperature and humidity sensor to ensure that the product has high reliability and excellent long-term stability. The rain gauge is a piezoelectric weighing rain gauge, which mainly consists of a rain collector, a weighing body, a sensor, a recorder, etc. The rain collector collects rainwater, and the weighing body weighs the collected rainwater. The sensor converts the gravity received by the weighing body into an electrical signal, and the magnitude of the electrical signal is proportional to the weight of the rainwater. The recorder calculates and records the precipitation according to the electrical signal transmitted by the sensor. This rain gauge can measure the total precipitation of each rainfall, and can also obtain the change of precipitation over time through continuous recording. Since it measures precipitation by weighing, it is not affected by factors such as rainwater evaporation and splashing, and has a high measurement accuracy, especially suitable for measuring solid precipitation such as snow and hail. The wind speed and direction sensor can output through multiple communication interfaces (RS232, RS485, etc.), and uses the relationship between the speed of ultrasonic waves propagating in the air and the wind speed to measure the wind speed, and can continuously measure the wind speed.

[0026] The wind speed sensor of the present invention is composed of two pairs of ultrasonic transducers. One pair is used to transmit ultrasonic waves, and the other pair is used to receive ultrasonic waves. When ultrasonic waves propagate in the air, their propagation speed will be affected by the wind speed. When the ultrasonic waves propagate along the wind direction, their propagation speed will increase; when the ultrasonic waves propagate against the wind direction, their propagation speed will decrease. By measuring the time difference or frequency difference of the ultrasonic waves propagating in the downwind and upwind directions, the wind speed can be calculated. The range of this sensor for measuring wind speed is 0.5 - 65 m / s, and the maximum allowable error is ±0.5 m / s; when measuring the wind direction, the measurement range is 0° - 360° (wind speed is 0.5 - 65 m / s). This sensor has high precision, fast response speed, is not affected by environmental temperature and humidity, and can measure wind speed and wind direction simultaneously;

[0027] The barometric pressure sensor in this embodiment is a capacitive barometric pressure sensor, which generally consists of a fixed electrode and a movable electrode. The movable electrode is generally composed of an elastic diaphragm. A capacitor is formed between the two electrodes. Its working principle is that when the atmospheric pressure acts on the elastic diaphragm, the diaphragm will deform, thus changing the distance between the two electrodes. According to the capacitance calculation formula, the change in the electrode spacing will cause a change in capacitance. By measuring the change in capacitance, the magnitude of the atmospheric pressure can be calculated. This kind of sensor has high precision, good stability and small temperature coefficient.

[0028] The GNSS high-precision positioning module in this embodiment adopts a low-cost and low-power board card, which is based on a BDS / GNSS dual-mode and dual-frequency chip. By using the innovative and developed precise measurement and real-time positioning technology, high-precision position data can be obtained. Under static baseline measurement, the horizontal accuracy is 1.7 mm and the vertical accuracy is 3.9 mm. It can realize landslide warning monitoring and real-time warning.

[0029] Specifically, the present invention has a multi-protocol hybrid communication system, which is compatible with wired interfaces (RS232, RS485, Ethernet) and wireless protocols (WiFi, BLE, 4G / LoRa) to achieve stable data transmission in complex environments. The data format is fully adapted to the ground observation specifications of the China Meteorological Administration and can be directly connected to the national meteorological network, supporting remote control and firmware upgrade. The maximum internal storage capacity of the present invention is 1 million groups. At the same time, the present invention also has an external storage interface, supporting SD cards and USB external USB flash drives to meet more data storage needs.

[0030] Optionally, the present invention integrates multi-mode GNSS (Beidou / GPS / GLONASS, etc.). By receiving the navigation signals transmitted by satellites from the antenna, positioning and calculation are completed to achieve precise positioning and time synchronization of the device. The positioning accuracy can reach a horizontal accuracy of 1.7 mm and a vertical accuracy of 3.9 mm; it improves the edge computing ability, reduces the dependence on the cloud for local data processing, and improves the short-term warning response speed (such as sudden strong wind warning).

[0031] Furthermore, the present invention has a high-reliability power supply and protection design, adopting dual 45W photovoltaic panels and a 30000mAh lithium battery pack to ensure at least 15 days of battery life in continuous rainy environments (with intermittent operation of the camera function); the overall machine has an IP65 protection level, can withstand extreme temperatures from -40°C to 70°C and strong wind impacts of 65 m / s. The shell adopts a lightweight modular structure (size 1280mm×651mm×2450mm, weight 40kg), which is convenient for rapid deployment and maintenance.

[0032] Furthermore, the present invention has extended functions and real-time video monitoring for data management. A video terminal system can be optionally installed to achieve visualization of meteorological scenes and support linkage analysis with meteorological data (such as real-time monitoring of waterlogging conditions during heavy rain); it has large-capacity storage and positioning time service: 1 million groups of data are stored internally, and an external SD card / USB can be used for expansion.

[0033] Optionally, the data detection module of this embodiment can achieve landslide monitoring and early warning, improve the edge computing ability, reduce the dependence on the cloud through local data processing, and improve the short-term early warning response speed. The data detection module is built with existing algorithms, which can refer to the invention patent named "A Geological Disaster Early Warning Method Based on Beidou Displacement Monitoring and Multiple Parameters", as well as the paper "Landslide Displacement Prediction Based on Improved Sparrow Optimization and SVR", published in the journal "Electronic Measurement Technology".

[0034] The integration and compatibility of the present invention break through the discrete layout of single sensors in traditional weather stations. Through the six-element integrated design, the installation complexity and maintenance cost are reduced; a GNSS high-precision positioning module is added to make up for the lack of landslide monitoring; multi-protocol communication is seamlessly connected with the national meteorological network to solve the data island problem. It also takes into account environmental adaptability and reliability. The solar-lithium battery hybrid power supply scheme supports off-grid operation, filling the monitoring gap in remote areas; the IP65 protection and wide temperature range design are suitable for harsh environments such as deserts, oceans, and plateaus. The integration of the video terminal and meteorological data also enhances the visual analysis ability of the disaster site; edge computing optimizes the data transmission efficiency and reduces the dependence on the central server.

[0035] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, based on the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
