Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of solar photovoltaic, and particularly relates to a remote monitoring device for a solar photovoltaic panel. BACKGROUND

[0002] In recent years, photovoltaic power stations are recommended as the first choice of power generation system of main renewable energy, and many power generation facilities and infrastructures required for operation thereof are developed. The solar power station is a direct current power supply part, converts sunlight from a solar cell module into electric energy, and delivers the electric energy to an inverter. An alternating current power supply part converts direct current into alternating current through the inverter, and delivers the alternating current to a power grid. The solar power station generates electric power. It is divided into a monitoring part for managing the power generation of a plant.

[0003] The existing foreign patent with the publication number US12224705B2 discloses a monitoring / control system for a solar power generation site, wherein a large number of solar modules include a plurality of solar cell groups, each of which includes a plurality of solar cells, wherein the power generation output of each solar cell group is connected to a parallel connection line from a unit group controller to a module and a parallel connection line from an optimizer to a polarity module, and is concentrated in a junction box. The monitoring / control system includes a relay terminal that collects data of the unit group controller and accumulates data of the optimizer, a server that includes a communication control device, and performs an upload / download process of management / control data through a public telecommunication network. A relay terminal and a remote terminal of an integrated management site, and a remote information terminal installed at a remote site are included.

[0004] The above monitoring device can monitor the damage of the solar unit and the shielding of foreign matters, but cannot effectively monitor the gradual accumulation of dust. Therefore, the monitoring device is improved. Content of the utility model

[0005] The application aims at the above-mentioned technical problems, and provides a remote monitoring device for a solar photovoltaic panel, which can remotely monitor the solar photovoltaic panel and ensure the power generation efficiency.

[0006] The application provides a remote monitoring device for a solar photovoltaic panel, which comprises:

[0007] A solar cell array is provided with, for example, one solar cell module, which is composed of at least 4 solar cell units;

[0008] A unit controller is connected with corresponding solar cell units on the same solar cell module;

[0009] A terminal device is signal-connected with the unit controller;

[0010] A light source device is installed on the solar cell module.

[0011] A transparent film is placed in front of the light source device.

[0012] A UAV device is connected to the terminal device, and the UAV device is provided with a camera module.

[0013] The transparent film is horizontally connected to the surface of the solar cell unit.

[0014] The solar cell modules are arranged to form a solar cell array, and the solar cell array is placed on the ground or the roof of a factory building, etc. Each solar cell module is composed of at least four solar cell units, and each solar cell module has a corresponding unit controller. When a solar cell unit in the solar cell module is damaged or blocked by other foreign matter such as leaves or plastic bags, the power generation of the corresponding solar cell unit is greater than the average power generation of the solar cell units connected to the same unit controller by a preset value, and the connection between the unit controller and the solar cell unit is disconnected until the abnormal state is removed, thereby improving the stability of the solar cell module. The light source device is installed on the solar cell module, and emits light through the transparent film. When the surface of the solar cell module is polluted by dust, pollen, etc., the power generation efficiency is reduced, but the power generation efficiency of the corresponding solar cell units of the same solar cell module is similar, and cannot be detected by the unit controller. Since the pollution is uniform on the surface of the solar cell module, the UAV device detects the solar cell array, the camera module takes a picture of the brightness of the light source device through the transparent film, and transmits the data to the terminal device. The terminal device records and analyzes the data for easy management of the solar cell array.

[0015] Further, the solar cell module comprises:

[0016] A base;

[0017] A vertical frame;

[0018] A horizontal frame;

[0019] An inclination sensor is arranged on the base, the vertical frame, and the horizontal frame, respectively;

[0020] An inclination value acquisition module is connected to the inclination sensor and connected to the terminal device.

[0021] The base is placed on the foundation surface. The base, vertical frame, and horizontal frame are combined to form a support structure and are installed and connected to the solar cell unit. Some solar cell arrays distributed on mountainous areas may tilt due to changes in terrain. By setting up tilt sensors to monitor the tilting and movement of the solar cell modules, the tilt value acquisition module collects the detection values ​​of the tilt sensors and transmits the data to the terminal equipment for recording and analysis, thereby improving the early warning of the danger of solar cell modules tipping over.

[0022] Furthermore, it also includes:

[0023] A rain sensor is placed on one side of the solar cell array;

[0024] The snowfall sensor is placed on one side of the solar cell array and adjacent to the rain sensor;

[0025] The wind sensor is placed on one side of the solar cell array and adjacent to the rain sensor;

[0026] The weather data acquisition module is connected to the rain sensor, snowfall sensor, and wind sensor, and also has a signal connection with the terminal device.

[0027] Rainfall is detected by a rain sensor, snowfall by a snow sensor, and wind by a wind sensor. The weather acquisition module collects the values ​​detected by the rain, snow, and wind sensors and transmits the data to the terminal device for recording and analysis. When the values ​​detected by the rain, snow, and wind sensors exceed the preset values, an early warning is issued.

[0028] Furthermore, the solar cell module also includes:

[0029] A temperature sensor is placed on the back of the solar cell unit;

[0030] The temperature acquisition module is connected to the temperature sensor and also has a signal connection with the terminal device.

[0031] Temperature sensors are installed on the back of the solar cell units, with one temperature sensor for each solar cell unit. The temperature sensor detects the temperature of the solar cell unit when it is working, and the temperature acquisition module collects the temperature sensor values. One solar cell unit corresponds to one temperature acquisition module, and the data is transmitted to the terminal device for recording and analysis. When the temperature exceeds the preset range, an early warning is issued.

[0032] Furthermore, the light source device uses a white light source, and the transparent film uses a colored film.

[0033] When a white light source is used in the light source device, it emits red, green, or blue light through the colored film, making it easier to analyze and calculate the image data taken by the drone device during monitoring.

[0034] Furthermore, it also includes:

[0035] The first signal connection module is connected to the tilt value acquisition module, the weather acquisition module, and the temperature acquisition module;

[0036] The second signal connection module is placed on the drone device;

[0037] The third signal connection module is located on the terminal device.

[0038] The first signal connection module and the third signal connection module are connected via wired or wireless means, and the second signal connection module and the first signal connection module are connected via wireless means, which facilitates the drone to transmit the detected photos to the terminal device in real time.

[0039] The beneficial effects of this application are:

[0040] 1. The unit controller is used to monitor and control the operation of a single solar cell unit when it is damaged or blocked by foreign objects, so as to ensure the stability of the working efficiency of the solar cell module.

[0041] 2. The brightness of the light source device through the transparent film is photographed using a drone, and the data is recorded and analyzed using a terminal device to detect the degree of dust and other substances adhering to the surface of the solar cell module.

[0042] 3. Monitor the tilting and movement of the solar cell module by setting up a tilt sensor. Attached Figure Description

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0050] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0051] Example 1:

[0052] like Figures 1-3 As shown in the figure, this application provides a remote monitoring device for solar photovoltaic panels, including:

[0053] A solar cell array 100 is provided with a number of solar cell modules 110, wherein each solar cell module 110 is composed of at least four solar cell units 111;

[0054] The unit controller 200 is connected to the corresponding solar cell unit 111 on the same solar cell module 110;

[0055] The terminal device 300 is connected to the unit controller 200 via a signal connection.

[0056] The light source device 400 is mounted on the solar cell module 110;

[0057] A transparent film 410 is placed in front of the light source device 400;

[0058] The drone device 500 is connected to the terminal device 300 by a signal, and the drone device 500 is equipped with a camera module 510;

[0059] The transparent film 410 is horizontally connected to the surface of the solar cell unit 111.

[0060] Solar cell modules 110 are arranged to form a solar cell array 100. These solar cells are displayed on the ground or on factory rooftops. Each solar cell module 110 consists of at least four solar cell units 111. Each solar cell module 110 has a corresponding unit controller 200. When a solar cell unit 111 within a solar cell module 110 is damaged or obstructed by foreign objects such as leaves or plastic bags, and the difference between the power generation of that solar cell unit 111 and the average power generation of the solar cells 111 connected to the same unit controller 200 exceeds a preset value, the unit controller 200 disconnects the solar cell unit 111 until the abnormal state is resolved, thus improving the efficiency of the solar cell module 110. To ensure stability, the light source device 400 is installed on the solar cell module 110. The light emitted by the light source device 400 passes through the transparent film 410. When the surface of the solar cell module 110 is contaminated by dust (fine dust), pollen, etc., the power generation efficiency is reduced. However, the power generation efficiency of the solar cell units 111 corresponding to the same solar cell module 110 is similar and cannot be detected by the unit controller 200. Since the contamination affects the surface of the solar cell module 110 more uniformly, the solar cell array 100 is detected by the drone device 500. The camera module 510 takes pictures of the brightness of the light source device 400 passing through the transparent film 410 and transmits the data to the terminal device 300. The terminal device 300 records and analyzes the data to facilitate the management of the solar cell array 100.

[0061] Furthermore, it also includes:

[0062] Rain sensor 610 is placed on one side of solar cell array 100;

[0063] The snowfall sensor 620 is placed on one side of the solar cell array 100 and is adjacent to the rain sensor 610;

[0064] The wind sensor 630 is placed on one side of the solar cell array 100 and adjacent to the rain sensor 610;

[0065] The weather data acquisition module 640 is connected to the rain sensor 610, the snowfall sensor 620, and the wind sensor 630, and is also connected to the terminal device 300 via a signal connection.

[0066] Rainfall is detected by a rain sensor 610, snowfall by a snow sensor 620, and wind by a wind sensor 630. The weather acquisition module 640 collects the values ​​detected by the rain sensor 610, snowfall sensor 620, and wind sensor 630, and transmits the data to the terminal device 300 for recording and analysis. When the values ​​detected by the rain sensor 610, snowfall sensor 620, and wind sensor 630 exceed a preset value, an early warning is issued.

[0067] Furthermore, the light source device 400 uses a white light source, and the transparent film 410 uses a colored film.

[0068] When the light source device 400 uses a white light source to pass through the colored film, it emits colored light such as red, green, or blue, making it easier for the image data captured by the drone device 500 during monitoring to be analyzed and calculated.

[0069] Furthermore, it also includes:

[0070] The first signal connection module 700 is connected to the tilt value acquisition module 116, the weather acquisition module 640, and the temperature acquisition module 118;

[0071] The second signal connection module 520 is mounted on the UAV device 500;

[0072] The third signal connection module 310 is placed on the terminal device 300.

[0073] The first signal connection module 700 and the third signal connection module 310 are connected via wired or wireless means, and the second signal connection module 520 is connected via wireless means to the first signal connection module 700, so that the drone can transmit the detected photos to the terminal device in real time.

[0078] Horizontal frame 114;

[0079] Tilt sensors 115 are respectively placed on base 112, vertical frame 113, and horizontal frame 114;

[0080] The tilt value acquisition module 116 is connected to the tilt sensor 115 and is also connected to the terminal device 300 via a signal connection.

[0081] The base 112 is placed on the foundation surface. The base 112, vertical frame 113, and horizontal frame 114 are combined to form a support structure and are installed and connected to the solar cell unit 111. Some solar cell arrays 100 distributed on mountainous areas may tilt due to changes in terrain. The tilt sensor 115 is set to monitor the tilting and movement of the solar cell module 110. The tilt value acquisition module 116 collects the detection values ​​of the tilt sensor 115 and transmits the data to the terminal device 300 for recording and analysis, so as to improve the early warning of the danger of the solar cell module 110 tilting.

[0082] Furthermore, the solar cell module 110 also includes:

[0083] Temperature sensor 117 is located on the back of solar cell unit 111;

[0085] Temperature sensor 117 is installed on the back of solar cell unit 111. Each solar cell unit 111 corresponds to one temperature sensor 117. Temperature sensor 117 detects the temperature of solar cell unit 111 when it is working. Temperature acquisition module 118 collects the value of temperature sensor 117. One solar cell unit 110 corresponds to one temperature acquisition module 118. The data is transmitted to terminal device 300 for recording and analysis. When the temperature exceeds the preset value range, an early warning is issued.
