Description

Technical Field

[0001] This utility model, a dynamic monitoring device for wind and sand based on a TOF photoelectric sensor, belongs to the field of wind and sand environment monitoring technology. Background Technology

[0002] Soil wind erosion, a core cause of soil desertification, triggers severe weather disasters such as sandstorms and dust storms, causing immense damage to the ecological environment and severely impacting human production and lives. For example, frequent sandstorms lead to a sharp decline in air quality, harming human health, burying farmland, damaging infrastructure, and causing huge economic losses. Wind erosion is generally monitored by wind erosion volume, which refers to the difference between the mass of surface material blown away by the wind and the amount deposited within a certain period—essentially, the change in ground elevation. Therefore, accurate and real-time monitoring of wind and sand dynamics is crucial for preventing wind erosion disasters and reducing their severity, providing key data support for formulating effective ecological protection and disaster prevention decisions.

[0003] In the current field of wind and sand dynamic monitoring, various technical methods already exist. Existing patent CN213301049U (application date: November 23, 2020) discloses a simple monitoring device for wind erosion and deposition, including a monitoring device body. A conical probe is installed at the bottom of the monitoring device body, zeroing plates are installed on the lower left and right sides of the monitoring device body, connecting rods are installed on the upper left and right sides of the monitoring device body, a connecting seat is installed on the top of the outer side of the connecting rod, a photovoltaic panel is installed on the top of the connecting seat, a battery is installed in the upper inner cavity of the monitoring device body, a GPS positioning system is installed on the top of the battery, and an indicator light is installed on the top outer wall of the monitoring device body. However, this utility model patent requires manual observation for monitoring wind erosion and deposition, which is labor-intensive, and the measurement data cannot be uploaded, reducing the efficiency of wind erosion and deposition monitoring. Utility Model Content

[0004] To address the technical problems in wind and sand monitoring, such as high manpower consumption, inability to upload measurement data, and inability to obtain real-time wind and sand change data, this invention proposes a dynamic wind and sand monitoring device based on a TOF photoelectric sensor.

[0005] To solve the above-mentioned technical problems, the specific technical solution of this utility model is as follows:

[0006] Wind and sand dynamic monitoring device based on TOF photoelectric sensor, such as Figure 1 As shown, it includes a main control unit and a wind erosion bridge assembly, with the main control unit and the wind erosion bridge assembly spaced apart.

[0007] The main control unit includes a support column 1, a distribution box 2 is provided in the lower middle part of the support column 1, and a main control box 3 is provided in the lower middle part of the support column 1 and on the back of the distribution box 2; a solar panel 4 is provided in the upper middle part of the support column 1, and the solar panel 4 is fixed to one side of the support column 1 by a connecting rod.

[0008] The wind erosion bridge assembly includes a sensor, a level 5, and a wind erosion bridge.

[0009] The sensors include a stress sensor 10 and a TOF photoelectric sensor 9.

[0010] The wind-eroded bridge includes two columns 6, a crossbeam 7, and a ground beam 8. The crossbeam 7 is fixedly connected to the top of the two columns 6, and the ground beam 8 is fixedly connected to the bottom of the two columns 6 at a height of 1 / 4. The bottom of the two columns 6 is inserted downward below the ground surface, and the ground beam 8 is buried below the ground surface. A level 5 is provided on the upper surface of the crossbeam 7, and multiple TOF photoelectric sensors 9 are spaced apart on the lower surface of the crossbeam 7. Multiple stress sensors 10 are spaced apart on the lower surface of the ground beam 8. The installation positions of the TOF photoelectric sensors 9 and the stress sensors 10 correspond one-to-one.

[0011] The sensor is connected to the main control box 3.

[0012] The beneficial effects of this invention are as follows: This invention proposes a dynamic monitoring device for wind and sand based on a TOF photoelectric sensor. Multiple stress sensors and TOF photoelectric sensors, arranged in a one-to-one correspondence, are set on a wind-eroded bridge to form a sensor array. This array measures the height of wind and sand at different locations, thereby obtaining information on the wind and sand accumulation in the area. The measurement process is more intelligent and the measurement accuracy is higher, greatly improving measurement efficiency and precision. By using a sensor array mode formed by stress sensors and TOF photoelectric sensors to monitor wind and sand conditions, real-time and uninterrupted monitoring of wind and sand is possible, making the collected data more accurate and comprehensively reflecting the wind and sand activity, avoiding deviations in the collected data. Simultaneously, no on-site monitoring by personnel is required, reducing the need for wind and sand monitoring. The process is labor-intensive, making monitoring more automated and intelligent. This monitoring device, through the on-site installation of high-precision sensors, can directly acquire accurate data on wind and sand height and wind erosion conditions, unaffected by sandstorm weather. It can provide more detailed and accurate data information for wind and sand monitoring in local areas. Combined with the data processing unit, it integrates and analyzes the stress change data from the stress sensor on the wind-eroded bridge and the distance data from the TOF photoelectric sensor, which can fully utilize the complementarity of multi-source data to improve the accuracy and reliability of monitoring results, providing stronger data support for the research and prevention of wind and sand environments. At the same time, this monitoring device is equipped with a wireless communication module, which can transmit real-time monitoring data to a remote terminal, realizing remote control of the monitoring device and data viewing. Attached Figure Description

[0013] Figure 1 This figure is a dynamic monitoring device for wind and sand based on a TOF photoelectric sensor, and is also included as an abstract drawing. Detailed Implementation

[0014] The present invention will be further described below.

[0015] like Figure 1 As shown, the distribution box 2 is equipped with a lithium battery pack, and the solar panel 4 replenishes the lithium battery pack with power to ensure the normal operation of the monitoring device. When the lithium battery pack power is lower than the set value, it automatically switches to charging mode; when the lithium battery pack is fully charged, it automatically stops charging to protect the lifespan of the lithium battery pack.

[0016] The main control box 3 contains a microcontroller, a wireless communication module, a data processing unit, and a display and control module;

[0017] The system includes multiple microcontrollers that control sensors, collect data from them, and transmit the collected data to the data processing unit in real time. Each microcontroller is programmed to control a corresponding sensor to monitor sandstorm height, wind erosion conditions, and collect the monitored data.

[0018] The wireless communication module adopts the LoRa wireless standard, supports multiple network standards, adapts to different deployment scenarios, integrates the MQTT protocol, and can communicate with remote terminals to realize real-time data transmission and control command reception. Through preset related functions, the monitoring device becomes more intelligent.

[0019] The data processing unit processes and stores the data monitored by the sensors in real time, enabling parallel acquisition of data from multiple sensors to improve data acquisition efficiency. It also fuses the multi-source data and transmits the processed data to the display and control module and remote terminal in real time. This allows the output fused data to more accurately reflect information such as the trend of wind and sand height changes, the intensity and direction of wind erosion. Furthermore, through data fusion and analysis, the complementarity of multi-source data can be fully utilized to improve the accuracy and reliability of monitoring results, providing stronger data support for the research and prevention of wind and sand environments.

[0020] The display and control module integrates a graphical interface for parameter setting, data querying, and monitoring mode switching. It displays real-time data on wind and sand height and wind erosion conditions in the form of charts and curves, making it convenient for staff to view relevant data changes.

[0021] The wind erosion bridge components are arranged in multiple sets at equal intervals, ranging from 5m to 10m. These wind erosion bridges are typically made of high-strength, wind-erosion-resistant materials, such as special steel or high-performance composite materials, to ensure long-term stable operation in harsh wind and sand environments. By using multiple identical wind erosion bridge components, the measured data on wind and sand height and wind erosion conditions become more accurate and representative.

[0022] The main control box 3 and the sensors are powered through the power distribution box 2.

[0023] The main control box 3 is also equipped with a meteorological interface. When it is necessary to measure meteorological data, such as wind speed and wind direction, the meteorological interface can be used in combination with relevant meteorological sensors to make the device's measurement more diversified and convenient and faster.

[0024] The working principle of this invention is as follows: The monitoring device is positioned above the area to be monitored for sandstorms, with the main control unit and wind erosion bridge components installed at intervals above the sandstorm area. The interval between each set of wind erosion bridge components is selected according to the monitoring requirements. When not monitoring sandstorms, the monitoring device is in standby mode. At this time, except for the stress sensor on the wind erosion bridge which is powered, all other parts stop working to save power. According to the preset program, when the stress sensor on the wind erosion bridge detects a change, the entire device is activated and begins monitoring sandstorms. The stress sensor and TOF photoelectric sensor on the wind erosion bridge simultaneously measure and obtain data. The data is stored and fused by the data processing unit to obtain the final data, which is displayed in real time on the display and control module and transmitted to a remote terminal in real time. The standby time is preset according to the sandstorm changes. If the monitoring device does not detect any data changes after the preset time, the device automatically enters standby mode, thus completing one sandstorm monitoring cycle.
