[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides, for example Figs. 1-5 The photovoltaic power station smart dust early warning and linkage system shown includes a dust detection module, an early warning module, a cleaning module, a dust control module, and a data monitoring and processing system.

[0039] The dust detection module detects the dust coverage and thickness on the surface of the photovoltaic module in real time;

[0040] The early warning module issues an early warning signal when dust accumulation reaches a preset threshold.

[0041] The cleaning module uses a blowing method to clean the surface dust of the photovoltaic modules;

[0042] The dust control module processes dust generated in the blowing process of the cleaning module by spraying and dust absorption

[0043] The dust detection module, the early warning module, the cleaning module and the dust control module are electrically connected with the data monitoring and processing system respectively.

[0044] The data monitoring and processing system processes the detected dust coverage and thickness data, triggers the early warning module to send an early warning signal when the dust accumulation reaches a preset threshold, controls the cleaning module to perform cleaning work, and controls the dust control module to suppress dust generated in the cleaning process.

[0045] First, the dust detection module detects the dust coverage and thickness of the surface of the photovoltaic module in real time, and transmits the detection data to the early warning module and the data monitoring and processing system. Then, the early warning module receives the detection data, and when it is determined that the dust accumulation reaches a preset threshold (the preset threshold in the early warning module is set by experimental test of the influence of different dust thickness on the operation of the photovoltaic module, and finally the threshold is set at the balance point of the safety interval and the early warning response time), an early warning signal is sent. Subsequently, the cleaning module receives the early warning signal of the early warning module and starts cleaning work, and at the same time, the dust control module and the cleaning module are synchronously linked to suppress dust generation during the cleaning process. Finally, the data monitoring and processing system receives and stores the operation data of the dust detection module, the early warning module, the cleaning module and the dust control module in real time, realizes whole-process data supervision, and thus builds a complete linkage system of detection-early warning-cleaning-dust control, replaces the traditional manual inspection mode, solves the problems of non-real-time manual monitoring, slow cleaning response and dust pollution, reduces the influence of excessive dust accumulation on the power generation efficiency of the photovoltaic module, and ensures the stable operation of the power station foundation.

[0046] The data monitoring and processing system comprises a remote monitoring module, a data transmission module and a central processing module, and the remote monitoring module and the data transmission module are electrically connected with the central processing module.

[0047] The data transmission module transmits the detection data of the dust detection module.

[0048] The central processing module receives and analyzes the detection data of the data transmission module.

[0049] The remote monitoring module realizes remote monitoring and management of the photovoltaic module.

[0050] The data transmission module receives real-time detection data of the dust detection module, transmits the data to the central processing module, the central processing module analyzes and processes the detection data (such as judging whether the dust meets the standard, matching the corresponding strategy), and feeds back the processing result to the remote monitoring module, the remote monitoring module receives the processing result, the staff can real-time view the dust monitoring situation of the power station, the data processing result through the module, and can also remotely issue management instructions (such as adjusting the early warning threshold, controlling the start and stop of the cleaning module);

[0051] Therefore, the function division of the data monitoring and processing system is refined, the data transmission module guarantees the timeliness and accuracy of data transmission, the central processing module realizes intelligent analysis of data, and the remote monitoring module breaks the geographical restriction, solves the problems of on-site duty and decision lag in traditional manual management, improves the flexibility and scientificity of power station operation and maintenance, and reduces the cost of manual management.

[0052] The dust detection module comprises an optical sensor, an image acquisition device and a dust thickness sensor, and the optical sensor is electrically connected with the image acquisition device and the dust thickness sensor respectively;

[0053] The optical sensor indirectly obtains dust coverage information by detecting the change of the light transmittance of the photovoltaic module;

[0054] The image acquisition device photographs the surface of the photovoltaic module to obtain image information of the surface of the photovoltaic module, thereby assisting in analyzing the dust distribution state;

[0055] The dust thickness sensor is used for directly detecting the dust accumulation thickness on the surface of the photovoltaic module;

[0056] The optical sensor, the image acquisition device and the dust thickness sensor work cooperatively to realize multi-dimensional detection of the dust state on the surface of the photovoltaic module;

[0057] When the dust detection module is started, first, the optical sensor is used to detect the change of the light transmittance of the photovoltaic module in real time (a decrease in light transmittance reflects dust accumulation), and the data is synchronously transmitted to the image acquisition device and the dust thickness sensor; after receiving the light transmittance data, the image acquisition device starts to photograph the image of the surface of the photovoltaic module to obtain visual information of the dust coverage, and simultaneously transmits the image data to the dust thickness sensor; then the dust thickness sensor emits a laser beam of a specific wavelength to the surface of the photovoltaic module, the laser is reflected by the surface of the dust layer and is captured by a receiving device, the time difference (or phase difference) between the emission and reception of the laser is calculated, combined with the speed of light parameter, the distance between the sensor and the surface of the dust layer is obtained, and then compared with the preset reference distance from the sensor to the surface of the clean module, the difference is the dust thickness; after the three-dimensional data of light transmittance, image and thickness are integrated through the cooperation of the three, the data is transmitted to the early warning module and the data monitoring and processing system;

[0058] According to the above description, multiple sensors are used for cooperative detection to avoid detection errors of a single sensor (for example, an optical sensor is easily disturbed by light, and an image acquisition device is difficult to measure thickness); the transmittance data reflect the indirect influence of dust, the image information directly shows the coverage range, the thickness data accurately quantify the accumulation degree, and the three-dimensional data are combined to realize comprehensive and accurate monitoring of the dust state, providing reliable data support for subsequent early warning and cleaning, and reducing the problems of missed detection and false detection caused by inaccurate detection.

[0059] The early warning module includes a multi-level early warning unit, a multi-channel release unit, and an early warning linkage unit, the multi-level early warning unit and the multi-channel release unit are electrically connected with the early warning linkage unit, and the multi-level early warning unit is electrically connected with the central processing module;

[0060] The multi-level early warning unit receives the dust detection data transmitted by the central processing module, divides the early warning levels (such as first, second, and third levels) in combination with the preset threshold, synchronously transmits the early warning level signals to the multi-channel release unit and the early warning linkage unit, the multi-channel release unit receives the signals and releases the early warning information through the preset channel (such as sound and light, APP, and monitoring center), the early warning linkage unit receives the early warning signals and directly links with the cleaning module, triggers the corresponding cleaning preparation or start instruction according to the early warning level, so that the multi-channel release unit and the early warning linkage unit synchronously feed back the early warning processing progress to the multi-level early warning unit, forming an early warning closed loop, thereby realizing early warning refinement of the multi-level early warning unit, avoiding excessive or insufficient response caused by single early warning, ensuring that the multi-channel release unit reaches the comprehensive early warning information, reducing the risk of staff omission, directly connecting the early warning linkage unit with the cleaning module, solving the problems of disconnection between traditional early warning and cleaning and slow response, and improving the cooperation efficiency of early warning and cleaning.

[0061] The multi-channel release unit includes a sound and light alarm installed on site, a mobile terminal push APP, and a monitoring center alarm, and the sound and light alarm, the mobile terminal push APP, and the monitoring center alarm are electrically connected with the early warning linkage unit of the early warning module;

[0062] After the multi-channel release unit receives the early warning signals of the multi-level early warning unit, it synchronously triggers three types of release terminals, the on-site sound and light alarm starts (emits sound and light prompts to remind on-site personnel), the mobile terminal push APP sends an early warning SMS push (including early warning area and level) to the operation and maintenance personnel, and the monitoring center alarm triggers an alarm (such as a pop-up window on a large screen and a sound reminder). While releasing the early warning information, the three types of terminals establish a signal connection with the cleaning module, and when the staff confirms the early warning through any terminal, they can directly issue a start instruction to the cleaning module;

[0063] Solve the problem of traditional single early warning channel (such as only on-site alarm) easy to cause early warning failure due to personnel not in place; Each channel directly links to the cleaning module to shorten the response time of early warning-confirmation-cleaning and ensure that early warning information is quickly converted into actual action.

[0064] The multi-level early warning unit includes a first-level early warning, a second-level early warning, and a third-level early warning, and is electrically connected with the dust thickness sensor in the dust detection module;

[0065] The multi-level early warning unit judges the data according to the preset thickness threshold range. If the thickness is in the low threshold interval, the first-level early warning is triggered; if the thickness is in the medium threshold interval, the second-level early warning is triggered; and if the thickness is in the high threshold interval, the third-level early warning is triggered. Different levels correspond to different processing priorities, which can guide the cleaning module to allocate resources as needed (such as cleaning priority for third-level early warning), reduce waste of cleaning resources, and improve the pertinence and efficiency of cleaning tasks.

[0066] The dust raising control module includes a pretreatment unit, a dust suppression control unit, and a dust sensor, the pretreatment unit and the dust sensor are electrically connected with the dust suppression control unit, and the dust suppression control unit is electrically connected with the central processing module;

[0067] The dust sensor monitors the dust concentration (such as environmental dust before cleaning and dust raised during cleaning) of the cleaning area of the photovoltaic module in real time, converts the concentration data into an electrical signal, and transmits it to the dust suppression control unit in real time. The central processing module synchronously sends the dust thickness data of the dust detection module and the cleaning start instruction of the cleaning module to the dust suppression control unit to provide a comprehensive basis for dust suppression strategy. After receiving the concentration data of the dust sensor and the associated data of the central processing module, the dust suppression control unit judges the current scene (such as pretreatment before cleaning and real-time dust suppression during cleaning). If the dust concentration before cleaning is higher than the preset threshold or the cleaning module receives a start warning, the dust suppression control unit issues a start instruction to the pretreatment unit. If the dust concentration during cleaning exceeds the standard, the dust suppression control unit issues a parameter adjustment instruction (such as increasing the spraying amount or improving the dust suction power) to the pretreatment unit or other dust suppression components (such as a dust suction device). After the pretreatment unit executes the instruction (such as atomizing spraying and pre-dust suction), the dust sensor continues to monitor the change of dust concentration and returns the data to the dust suppression control unit. The dust suppression control unit dynamically optimizes the instruction (such as reducing the power of the pretreatment unit when the concentration drops to a safe value) according to the feedback data, and returns the dust suppression state (such as equipment operation and concentration change) to the central processing module to form a closed-loop control of monitoring-analysis-execution-feedback.

[0068] The pretreatment unit includes an atomizing spraying device and a dust suction device. The atomizing spraying device can form a wet environment to suppress dust raising, and the dust suction device can suck up the raised dust;

[0069] The pre-processing unit synchronously starts the atomizing spraying device and the dust suction device after receiving the start signal of the dust sensor or the cleaning module, the atomizing spraying device sprays atomized water to the cleaning area, a wet environment is formed on the surface of the photovoltaic module and the surrounding ground, the dust flying property is reduced, the dust suction device is started synchronously, the dust raised in the cleaning area is sucked and removed, and the dust is prevented from spreading to the uncleaned area, the two work cooperatively, when the humidity of the cleaning area reaches the preset value and the dust concentration is reduced to the safe range, the pre-processing unit sends a cleanable signal to the cleaning module, and the dust suction device is kept at low power at the same time, which cooperates with the cleaning module to work, after the cleaning is completed, the pre-processing unit closes the atomizing spraying device, and after the dust suction device sucks the residual dust, the operation is stopped and the state is fed back, the specific execution means of the pre-processing unit is clear, the atomizing spraying device suppresses the dust flying (wet dust) from the source, and the dust suction device actively absorbs the wet dust or dust flying through the suction nozzle, solves the problem that the traditional cleaning is easy to cause the photovoltaic module to accumulate water only by spraying and is easy to miss the source dust only by dust suction, while ensuring the dust suppression effect, the additional damage (such as water short circuit) to the photovoltaic module is avoided.

[0070] The cleaning module comprises an execution unit, a cleaning detection unit and an energy management unit, the execution unit is electrically connected with the cleaning detection unit, and the energy management unit is electrically connected with an external power supply device.

[0071] After receiving the start instruction of the early warning linkage unit, the execution unit (such as a cleaning robot) starts the cleaning operation, the cleaning detection unit is started synchronously, and the cleaning progress (such as the cleaning area and the cleaning time) and the cleaning effect (such as the residual dust amount after cleaning) of the execution unit are monitored in real time, and the data is transmitted to the execution unit, the execution unit dynamically adjusts the cleaning parameters (such as the cleaning intensity and the path) according to the feedback of the cleaning detection unit, so as to ensure that the cleaning meets the standard, and the energy management unit monitors the energy consumption of the execution unit in real time, and is linked with the external power supply device, so as to automatically switch the charging mode (such as photovoltaic auxiliary charging and external power supply charging) when the power is insufficient, and ensure the continuous operation of the execution unit.

[0072] The execution unit comprises a cleaning robot, a visual navigation device is arranged on the cleaning robot, and the visual navigation device is used for identifying and positioning the path of the cleaning robot and shooting the image in the cleaning process of the surface of the photovoltaic module.

[0073] The visual navigation device is started synchronously after the cleaning robot is started, an image of the environment around the photovoltaic module is captured by the built-in camera, information such as the edge of the module and the obstacle in the channel is recognized, a cleaning path is planned and positioned, and the visual navigation device captures a surface image of the module in real time when the cleaning robot cleans along the planned path, records the dust state before cleaning and the surface change during cleaning, and synchronously transmits the path positioning image and the cleaning process image to the cleaning detection unit to determine whether the path is deviated and whether the cleaning effect meets the standard, if the path deviation (such as the robot deviating from the module area) is detected, the visual navigation device immediately adjusts the positioning parameters to guide the robot to correct the path, and if the incomplete cleaning (image shows residual dust) is detected, it is fed back to the execution unit to increase the cleaning times or intensity.

[0074] In specific use, first, the dust detection module works, the optical sensor detects the change of the light transmittance of the photovoltaic module in real time (the decrease of the light transmittance reflects the dust accumulation), and synchronously transmits the data to the image acquisition device and the dust thickness sensor, the image acquisition device immediately captures the surface image of the photovoltaic module, obtains the visual information of the dust coverage and transmits it to the dust thickness sensor, the dust thickness sensor combines the light transmittance data and the image information to accurately detect the dust accumulation thickness, finally, the three-dimensional data of light transmittance-image-thickness are integrated and transmitted to the central processing module through the data transmission module of the data monitoring processing system, the central processing module analyzes and processes the data, on the one hand, the results are fed back to the remote monitoring module for remote viewing by the staff, and on the other hand, the data are transmitted to the multi-level early warning unit of the early warning module, the multi-level early warning unit divides the early warning levels according to the preset dust thickness threshold (low threshold triggers a first level early warning, middle threshold triggers a second level early warning, and high threshold triggers a third level early warning), and synchronously transmits the early warning signal to the multi-channel publishing unit and the early warning linkage unit, the multi-channel publishing unit immediately starts the on-site sound and light alarm (emits sound and light prompts), pushes the APP to the operation and maintenance personnel mobile terminal to send information containing the early warning area and level, triggers the monitoring center alarm (such as a large screen pop-up window), and the early warning linkage unit directly links with the cleaning module to trigger the corresponding cleaning preparation or start instruction according to the early warning level;

[0075] When the cleaning module receives the start instruction, the execution unit (cleaning robot) starts immediately, the visual navigation device on the robot identifies the edge and obstacles by shooting environmental images, plans and positions the cleaning path, and the cleaning detection unit starts simultaneously to monitor the cleaning progress and cleaning effect in real time. If the path deviation or incomplete cleaning is found, the execution unit is adjusted in time to adjust the cleaning parameters. At the same time of starting the cleaning work, the dust raising control module works simultaneously, the dust sensor monitors the dust concentration in the cleaning area in real time, and the data is transmitted to the pretreatment unit and dust suppression control unit. The pretreatment unit starts the atomizing spraying device (spraying atomized water to form a humid environment to suppress the source of dust raising) and the dust suction device (sucking up the raised dust and humid dust), and the data monitoring and processing system receives and stores the running data of each module in real time during the whole process. The staff can supervise the whole process in real time through the remote monitoring module. After the cleaning is completed and the dust raising control module confirms that the dust concentration returns to normal, the system automatically records the work data of this time, and completes a complete dust early warning linkage cleaning work.
