Through the cooperation of the temperature sensor, the smoke sensor, the thermal imaging sensor and the high-definition camera, the fire warning data of the device room can be accurately collected through multiple channels, thereby improving the accuracy of data collection and reducing false positives. Through the cooperation of the voltage sensor and the current sensor, the running state of the solar photovoltaic panel and various devices in the photovoltaic device room can be monitored in real time.

[0055] The device fire prevention and state monitoring system applied to the photovoltaic area provided by the embodiment can collect temperature data, smoke concentration data and thermal radiation data of the photovoltaic area device through the fire monitoring unit, collect fire warning images through the monitoring unit, and collect running state data through the device state monitoring unit, thereby accurately collecting fire warning data of the photovoltaic area device, improving the accuracy of the fire warning data, and reducing the false positives of the device fire grade.

[0056] In an optional implementation, the data processing module 102 includes a data receiving unit 1021, a data processing unit 1022, a fire grade evaluation unit 1023 and a control unit 1024 connected in sequence. The data receiving unit 1021 is connected with the data collection module 101, and the control unit 1024 is connected with the fire extinguishing module 103.

[0057] The data processing unit 1022 is configured to detect smoke concentration and open fire based on the fire warning data, obtain smoke concentration detection results and open fire detection results, and send the smoke concentration detection results and the open fire detection results to the fire grade evaluation unit 1023.

[0058] The fire grade evaluation unit 1023 is configured to divide the fire grade based on the smoke concentration detection results and the open fire detection results, obtain the device fire grade, and send the device fire grade to the control unit 1024.

[0059] Specifically, after receiving the smoke concentration detection results and the open fire detection results sent by the data processing unit 1022, if the detection results are normal, the fire grade evaluation unit 1023 judges that the device fire grade is safe; if the detection results are abnormal, the fire grade evaluation unit 1023 divides the fire grade according to whether the smoke concentration is abnormal and whether there is open fire, and divides the fire grade according to three evaluation standards: abnormal smoke concentration without open fire, abnormal smoke concentration with weak fire, and abnormal smoke concentration with large-scale fire.

[0060] Further, the fire rating assessment unit 1023 divides the obtained equipment fire rating into safety, first fire, second fire and third fire. When the equipment fire rating is safety, it means no abnormal situation. When the equipment fire rating is first fire, it means abnormal smoke concentration in the photovoltaic equipment room without open fire. When the equipment fire rating is second fire, it means abnormal smoke concentration in the photovoltaic equipment room with weak fire. When the equipment fire rating is third fire, it means abnormal smoke concentration in the photovoltaic equipment room with large-scale fire.

[0061] The control unit 1024 is configured to generate a fire extinguishing instruction based on the equipment fire rating and send the fire extinguishing instruction to the fire extinguishing module 103.

[0062] Specifically, the control unit 1024 generates a fire extinguishing instruction according to the equipment fire rating; wherein the fire extinguishing instruction is used to control the fire extinguishing module 103 to extinguish fire.

[0063] The equipment fire prevention and state monitoring system applied to the photovoltaic area provided in the embodiment can realize accurate detection of equipment fire through the data processing unit based on fire warning data for smoke concentration detection and open fire detection. The fire rating assessment unit can divide the fire rating based on the smoke concentration detection result and the open fire detection result, so as to effectively divide the fire rating. The control unit can generate a fire extinguishing instruction based on the equipment fire rating, so that the fire extinguishing module can extinguish fire according to the equipment fire rating, thereby reducing the work burden of the staff and reducing the waste of human resources and the maintenance cost of the photovoltaic area equipment.

[0064] In an optional implementation, the fire extinguishing module 103 includes a first fire extinguishing assembly 1031, a second fire extinguishing assembly 1032 and a third fire extinguishing assembly 1033; wherein the control unit 1024 is connected with the first fire extinguishing assembly 1031, the second fire extinguishing assembly 1032 and the third fire extinguishing assembly 1033 respectively.

[0065] The first fire extinguishing assembly 1031 includes a first exhaust fan and a first smoke treatment device; the second fire extinguishing assembly 1032 includes an aerosol fire extinguishing device; and the third fire extinguishing assembly 1033 includes a perfluorohexone automatic fire extinguishing device, a second exhaust fan and a second smoke treatment device.

[0066] Specifically, the first fire extinguishing assembly 1031 includes an exhaust fan and a smoke treatment device, the second fire extinguishing assembly 1032 includes an aerosol fire extinguishing device, and the third fire extinguishing assembly 1033 includes a perfluorohexone automatic fire extinguishing device, an exhaust fan and a smoke treatment device; wherein the exhaust fan can timely exhaust the smoke in the photovoltaic equipment room and purify the smoke, the aerosol fire extinguishing device can realize point-to-point small-range fire extinguishing, and the perfluorohexone automatic fire extinguishing device can realize full-submersion large-scale fire extinguishing.

[0067] Further, the first-level fire extinguishing assembly 1031 is started when the equipment fire level is a first-level fire or a second-level fire, the second-level fire extinguishing assembly 1032 is started when the equipment fire level is a second-level fire, and the third-level fire extinguishing assembly 1033 is started when the equipment fire level is a third-level fire. The first-level fire extinguishing assembly, the second-level fire extinguishing assembly, and the third-level fire extinguishing assembly are controlled by the fire extinguishing instruction sent by the control unit 1024.

[0068] The device fire prevention and state monitoring system applied to the photovoltaic area provided in the embodiment can perform reasonable fire extinguishing operation based on the fire extinguishing instruction through the first-level fire extinguishing assembly, the second-level fire extinguishing assembly, and the third-level fire extinguishing assembly arranged in the fire extinguishing module and the corresponding fire extinguishing devices arranged for the first-level fire extinguishing assembly, the second-level fire extinguishing assembly, and the third-level fire extinguishing assembly, thereby reducing the resource waste of fire extinguishing and the maintenance cost of the fire extinguishing module.

[0069] In an optional implementation, the data processing unit 1022 is specifically configured to compare the fire warning data with a preset threshold value, perform foreground detection on the fire warning image to obtain a smoke concentration detection result and an open fire detection result if the fire warning data is greater than the preset threshold value, and send the smoke concentration detection result and the open fire detection result to the control unit.

[0070] Specifically, the data processing unit 1022 needs to set a preset threshold value before processing the fire warning data. The preset threshold value includes a temperature threshold value, a smoke concentration threshold value, a thermal radiation threshold value, and voltage threshold values and current threshold values of various devices of the photovoltaic device and the photovoltaic device.

[0071] Further, the data processing unit 1022 compares the fire warning data with the preset threshold value. If the fire warning data is greater than the preset threshold value, the data processing unit 1022 performs foreground detection on the fire warning image by using a ViBe (Visual Background Extractor) algorithm to obtain a smoke concentration detection result and an open fire detection result, and sends the smoke concentration detection result and the open fire detection result to the control unit 1024.

[0072] Further, the ViBe algorithm uses a method of initializing a background model by using a single frame, that is, the first frame of a video sequence is used to initialize the background model. For each pixel point in the fire warning image, a pixel value in the neighborhood of the pixel point is randomly selected as a background model sample value of the pixel point. For each new pixel point in the video sequence, the similarity of the new pixel point with the background model sample set is calculated, so as to realize monitoring of a flame, smoke, and other dynamic targets of the device in the photovoltaic area, obtain a smoke concentration detection result and an open fire detection result, and further provide key information for fire warning.

[0073] The device fire prevention and state monitoring system applied to the photovoltaic area provided in the embodiment can improve the dynamic background adaptability of the smoke concentration detection result and the open fire detection result by performing foreground detection on the fire warning image through the data processing unit, and further enhance the reliability of the device fire grade.

[0074] In an optional implementation, the data processing unit 1022 is further configured to construct an operation state curve model based on the fire warning data, and predict the fault risk of the photovoltaic area device by using the operation state curve model.

[0075] Specifically, the operation state data in the fire warning data is modeled and analyzed, and the abnormality is detected by comparing the difference between the actual data and the model data. When modeling, the corresponding operation state curve model is established based on the operation state data in the fire warning data, so that the data processing unit 1022 can compare the real-time operation state data received with the model data, and detect the abnormality of the device by comparing whether there is a difference between the two; wherein the model data is obtained by predicting through the operation state curve model.

[0076] Further, according to the operation state curve model, the future trend of the photovoltaic area device operation state data is predicted. When the operation state curve model fluctuates sharply, it means that the photovoltaic area device has a risk of failure, and the staff needs to strengthen the inspection and maintenance to eliminate the failure risk of the photovoltaic area device, and ensure the normal operation of the photovoltaic area device.

[0077] The device fire prevention and state monitoring system applied to the photovoltaic area provided in the embodiment can predict the fault risk of the photovoltaic area device by using the operation state curve model, realize the visualization of the operation state data of the photovoltaic area device, improve the convenience of the photovoltaic area device abnormality detection, and reduce the artificial inspection cost.

[0079] The warning module 104 is connected with the data processing module, and is configured to receive the device fire grade sent by the data processing module, and perform fault warning and fire grade warning based on the device fire grade.

[0080] Specifically, when the warning module 104 performs fault warning and fire grade warning, it performs on-site fire alarm through sound and light, and performs remote fault alarm and fire alarm through the way of short message and telephone. The warning module 104 can remind the staff on site of the fire in time by controlling the sound and light alarm on site, and can alarm the staff of the abnormal situation in time by the way of short message and telephone, so as to facilitate the staff to handle the situation on site in time.

[0081] The device fire prevention and state monitoring system applied to the photovoltaic area provided in the embodiment realizes precise early warning of the fire grade and the equipment failure, provides support for the emergency decision of the staff, and effectively improves the safety management efficiency of the equipment in the photovoltaic area.

[0082] In an alternative implementation, further comprising:

[0083] The data storage module 105 is connected with the data acquisition module 101 and the data processing module 102 respectively, and is used for receiving the fire warning data sent by the data acquisition module 101 and the equipment fire grade sent by the data processing module 102, and storing the fire warning data and the equipment fire grade.

[0084] Specifically, when storing the fire grade data and the fire warning data, the data storage module 105 stores the data in a combination of a relational database and cloud storage; the relational database organizes data through tables and rows, can efficiently store and manage the operation parameters, fault records, equipment fire grades and other information of the photovoltaic equipment, thereby facilitating the staff to query and read, and the cloud storage has good availability, scalability and security, and can reduce the operation and maintenance cost of data.

[0085] The device fire prevention and state monitoring system applied to the photovoltaic area provided in the embodiment stores the fire warning data and the equipment fire grade through the data storage module, provides data support for the daily maintenance and fault troubleshooting of the equipment in the photovoltaic area, and improves the accuracy and efficiency of operation and maintenance.

[0086] In an alternative implementation, further comprising:

[0087] The interactive module 106 is connected with the data storage module 105, is used for generating a query request, sending the query request to the data storage module, and receiving the fire warning data and the equipment fire grade fed back by the data storage module.

[0088] Specifically, the interactive module 106 includes a text input box, a query button component, and click, hover, zoom, and pan interaction functions, and is responsible for processing the input and query request of the user.

[0089] Further, after the staff inputs the data to be queried in the text input box and clicks the query button, the generation of the query request is completed, the query request is sent to the data storage module 105, and the data storage module 105 returns the corresponding fire warning data and equipment fire grade according to the query request.

[0090] The application provided by the embodiment provides a device fireproofing and state monitoring system applied to a photovoltaic area, sends a query request to a data storage module through an interaction module, and feeds back fire warning data and a device fire grade, thereby improving the efficiency and scientificity of operation and maintenance decision making, and realizing the intelligentization and high efficiency of photovoltaic area device management.

[0091] The working process of the device fireproofing and state monitoring system applied to the photovoltaic area is described below through an embodiment.

[0092] Embodiment 1

[0094] 2) The data processing module compares the fire warning data with the preset threshold value through the data processing unit, if the fire warning data is less than the preset threshold value, the data processing unit will send a corresponding safety signal to the control unit and the fire grade evaluation module, the control unit will transmit the safety signal to the fire extinguishing module and the warning module, and the warning module and the fire extinguishing module will not act.

[0095] 3) When the temperature, smoke concentration, heat radiation in the photovoltaic device, and voltage and current of various devices between the solar photovoltaic panel and the photovoltaic device (i.e. fire warning data) are greater than the preset threshold value, the data processing unit will generate a danger signal (i.e. smoke concentration detection result and open fire detection result) based on the fire warning information and send it to the fire grade evaluation unit.
