Description

Technical Field

[0001] The utility model relates to the technical field of weather stations, in particular to an automatic weather station operation situation perception and monitoring system. Background Art

[0002] A ground-based meteorological station refers to a weather station built in a certain area according to needs, which can automatically conduct all-weather on-site monitoring of meteorological elements such as wind speed, wind direction, and rainfall. It can automatically generate data files and transmit detection data to the central station at regular intervals without human intervention. It is an important means for the meteorological industry to fill the gaps in meteorological detection data in spatial areas.

[0003] Currently, ground-based meteorological stations primarily use mechanical sensors for wind observation. These sensors consist of a housing and a drive shaft. The drive shaft is rotatably connected to the housing via a bearing assembly, with a wind cup or vane fixed to the top of the drive shaft. To prevent dust, these sensors are designed with a small mounting gap. This small gap between the drive shaft and the housing can easily become stuck to rain or snow in cold, rainy, or snowy weather, freezing the wind sensor. This can prevent the sensor from rotating and affect wind observations.

[0004] Freezing of wind sensors is the main fault that occurs during the operation of automatic weather stations in winter, which will seriously affect the continuity of wind data. In order to solve this problem, every winter, personnel at each station need to climb onto a 10-meter-high wind pole to de-ice the wind sensor, which is not only unsafe but also affects the continuity of wind observation data. Therefore, in order to solve this problem, those skilled in the art have adopted a heating method to prevent freezing. For example, the patent with announcement number CN 219676030 U discloses an anemometer with an anti-freeze function, in which an air guide hood with a heating tube is provided on the outside of the anemometer body to prevent freezing by heating. However, the device also has the following disadvantages: on the one hand, the structure is complex and the production cost is high; on the other hand, the air guide hood is provided on the outside of the anemometer, which changes the wind flow field and affects the accuracy of the wind data.

[0033] In the description of the present invention, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a centrally located component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be a centrally located component.

They are only used to facilitate the description of the present invention, and do not indicate or imply that the components or elements referred to must have this specific orientation or operate in a specific orientation structure. They should not be understood as limitations of the present invention.

[0035] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0036] like Figure 1 - Figure 6As shown, this embodiment proposes an automatic weather station operation situation awareness monitoring system, including a ground weather station a, a video monitoring device b and a controller d. The ground weather station a includes a wind mast a1, and the bottom of the wind mast a1 has a base a2. The wind mast a1 is equipped with a measuring component, a photovoltaic component a5 and a control box a7. The measuring component includes at least a wind sensor a4; the control box a7 is provided with a microprocessor and a power supply, and the photovoltaic component a5 is electrically connected to the power supply; the photovoltaic component a5 is a conventional structure, which includes a solar panel, the solar panel is connected to a charge and discharge controller, the charge and discharge controller is connected to a power supply, and the solar panel converts solar energy into electrical energy and stores it in the power supply.

[0037] The wind sensor a4 is a wind speed sensor and / or a wind direction sensor. When the wind sensor a4 is a wind speed sensor, the top of the transmission shaft a42 is connected to the wind cup a43. Figure 2 When the wind speed sensor is a wind direction sensor, the top of the transmission shaft a42 is connected to a wind vane.

[0038] The power supply is electrically connected to the microprocessor, wind sensor a4, video monitoring device b and controller d for power supply. It also includes a de-icing component used in conjunction with wind sensor a4. When wind sensor a4 suffers from freezing, the de-icing component is used to deal with it. The controller d is controlled and connected to the measurement component, de-icing component and video monitoring device b respectively. The controller d serves as the brain of the entire platform and is used to achieve overall control.

[0039] As a feasible embodiment, the measurement assembly further includes at least a primary rain sensor a6 and a secondary rain sensor c. A power supply is electrically connected to the primary and secondary rain sensors a6 and c, and a controller d is controllably connected to the primary and secondary rain sensors a6 and c. In this embodiment, the primary rain sensor a6 is a piezoelectric rain sensor, while the secondary rain sensor c is a tipping bucket rain sensor. The purpose of designing one primary and one secondary rain sensor is to ensure that the tipping bucket rain sensor accurately measures light rain, while the piezoelectric rain sensor may not accurately measure light rain. This serves as an auxiliary measurement device to ensure the accuracy of the measured rainfall data. It should be noted that light rain, as used herein, refers to precipitation with an intensity of ≤1 mm / min.

[0040] It should be noted that the measurement component may also include one or more of a temperature and humidity sensor, a ground temperature sensor, an evaporation sensor, and an air pressure sensor, which can be selected and installed according to actual needs.

[0041] The de-icing assembly described above may adopt the following structural forms:

[0042] The first type of de-icing assembly includes an adjustment rod 1, a tubular structure with a cavity inside. The adjustment rod 1 is connected to a wind rod a1, which can be fixedly connected. The end of the adjustment rod 1 is connected to a ring 4, which is designed to fit over the housing of a wind sensor a4. The ring 4 has a cavity inside and communicates with the cavity inside the adjustment rod 1, forming a liquid supply pipeline. The inner wall of the ring 4 is circumferentially provided with a plurality of nozzles 41. The assembly also includes a liquid reservoir 11, which stores de-icing fluid. The liquid reservoir 11 is connected to the liquid inlet of a booster pump 12 via a pipeline. The liquid outlet of the booster pump 12 is connected to the cavity of the adjustment rod 1 via a hose 13. A controller d is controllably connected to the booster pump 12. When a freezing disaster occurs, the controller d activates the booster pump 12, pumping de-icing fluid from the liquid reservoir 11 through the liquid supply pipeline and spraying it out of the nozzles 41. Because the nozzles 41 are arranged circumferentially, they can spray de-icing fluid around the entire ice, thereby achieving comprehensive melting.

[0043] The deicing fluid in this embodiment can be refrigerator deicer or aircraft deicer. Refrigerator deicer, through its ingredients such as deionized water and an ice-melting factor dispersant, effectively dissolves ice. Aircraft deicing fluid (DF Plus) is a propylene glycol Type I aircraft deicing fluid. Considering cost, the deicing fluid can also be commercially available windshield washer fluid. Windshield washer fluid primarily consists of water, alcohol, ethylene glycol, corrosion inhibitors, and surfactants. The alcohol component significantly lowers the freezing point of the fluid, providing an antifreeze effect and rapidly dissolving frost. It is widely available and inexpensive.

[0044] The second method is to consider that after the adjustment rod 1 is fixedly connected, the nozzle 41 cannot move up and down and can only spray at one position, but cannot spray de-icing at other positions, which is quite limited. Therefore, based on the first method, an improvement is made: the top of the wind rod a1 is fixedly connected with a cross arm a3, and the shell a41 of the wind sensor a4 is bolted to the cross arm a3; the adjustment rod 1 is slidably connected to the wind rod a1, specifically: a clamp 3 is bolted to the wind rod a1, and a guide sleeve 2 is connected to one side of the clamp 3. The adjustment rod 1 freely passes through the guide sleeve 2, and the adjustment rod 1 can slide up and down relative to the guide sleeve 2. One end of the adjustment rod 1 freely passes through the cross arm a3, and the cross arm a3 is provided with a through hole a31 for the adjustment rod 1 to pass through; the bottom end of the adjustment rod 1 is connected to a pulley 8, and a cam 10 is provided below the pulley 8. The cam 10 is connected to the output shaft of the motor 9; the controller d is controlled and connected to the cam 10. Start the motor 9, which drives the cam 10 to rotate. During the rotation, the cam 10 drives the pulley 8 to move up and down, thereby realizing the up and down movement of the ring sleeve 4, thereby realizing the spraying of the upper and lower areas of the shell a41, increasing the deicing area and achieving better effect.

[0045] It should be noted that the motor 9, the liquid storage tank 11, the booster pump 12 and other equipment are centrally installed on the bracket 6, and the bracket 6 is connected to the outer wall of the wind pole a1, which can be bolted or welded; a detachable protective box 7 is also provided on the bracket 6, and the protective box 7 cover is provided on the motor 9, the liquid storage tank 11 and the booster pump 12 to achieve protection.

[0046] In order to facilitate the installation of the hose 13, a valve can be welded on the regulating rod 1, and the hose 13 is connected to the valve.

[0047] The third method, based on the second method, is to extend the bottom end of the transmission shaft a42 of wind sensor a4 through housing a41 and cross arm a3 to the bottom of cross arm a3. The bottom end of transmission shaft a42 is connected to an encoder 5, and a controller d is control-connected to encoder 5. Encoder 5 detects whether transmission shaft a42 is rotating. In winter, when ice freezes, transmission shaft a42 becomes frozen and cannot rotate. At this time, encoder 5 outputs a data value of 0, which is transmitted to controller d. If encoder 5 outputs a data value of 0 for a period of time, controller d determines that wind sensor a4 is frozen. Controller d activates booster pump 12 and motor 9 to spray deicing fluid. During spraying, nozzle 41 can move up and down to complete regional deicing.

[0048] Application results:

[0049] The designed de-icing component can effectively solve the freezing problem of wind sensor A4 during winter operation. The de-icing component uses de-icing fluid to quickly and efficiently melt the frost, allowing wind sensor A4 to quickly resume use and reduce the operational risks associated with freezing of wind sensor A4. This device has a simple structure, is easy to make, and is low-cost. More importantly, only a very small ring sleeve 4 is set on the wind sensor A4. The ring sleeve 4 has a small area and will not change the wind flow field and will not affect the accuracy of the wind data. In addition, by designing structures such as the motor 9 and the cam 10, the adjustment rod 1 can be moved up and down, and then the ring sleeve 4 can be moved up and down relative to the wind sensor A4. This can achieve regional thawing and better cope with freezing in different locations. On the basis of reducing the impact on the wind flow field, the regional thawing work can be better completed.

[0050] In this embodiment, the video monitoring device b includes a pole with a camera installed on the pole for monitoring and transmitting the monitoring data to the controller d for storage.

[0051] In this embodiment, a central server and a remote control terminal are also included. Controller D establishes a remote communication connection with the central server via a wired transmission module or a wireless transmission module. A data communication connection is established between the central server and the remote control terminal. The wireless transmission module can be one of an NB-IOT module, a LoRa module, a 4G module, or a ZigBee module.

[0052] In this embodiment, the remote control terminal is a laptop computer, a tablet computer, or a mobile phone, which facilitates the staff to view data remotely.

[0053] The automatic weather station operation situation awareness and monitoring system proposed in the present invention enables staff to timely grasp the operation status of the ground weather station a, and to timely discover and eliminate operation failures of the ground weather station a, thereby reliably guaranteeing the construction and operation of the ground weather station a.

[0054] This new system utilizes a variety of sensors and video surveillance devices to collect multi-channel information, including images, videos, and meteorological information, as well as monitor wind sensor operation, achieving a "one-machine, multi-functional" solution. This system builds an IoT (Internet of Things) for automatic weather station status awareness, enabling three-dimensional perception of the station's status, panoramic monitoring of channel conditions, and significantly improving operational and inspection efficiency. It also enhances the station's ability to withstand complex operating conditions and natural disasters, and promotes smarter, more efficient, and safer management of automatic weather stations.

[0055] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the utility model.
