The embodiment of the invention provides a fire monitoring method of a power system, which is applicable to timely finding and processing requirements of fire accidents of power distribution equipment in the power system.

Among them, the main control device 110, the respective environment sensors 120, and the respective image pickup devices 130 constitute the fire monitoring system 10.
The fire monitoring method will be described in detail with reference to fig. 2. Fig. 2 is a flow chart of a fire monitoring method of an electric power system according to an embodiment of the present invention. As shown in fig. 2, the fire monitoring method of the power system includes:
s110, acquiring environment sensing information corresponding to each power distribution device from each environment sensor, and determining a first fire judgment result of each power distribution device according to each environment sensing information.
The environment sensing information corresponding to any power distribution equipment comprises environment information of a fire risk area of the power distribution equipment. The fire risk area is a certain area including the power distribution equipment. The fire risk areas of different power distribution devices may be determined based on the type, importance, voltage class, etc. of the power distribution device.
The type and number of environmental sensors may be set according to actual requirements. A sensor is a device capable of converting physical characteristics (such as temperature, light intensity, etc.) into an electrical signal, and the structure of the sensor is generally composed of a sensing element, a converter, a signal processor, and the like. Since the power distribution apparatus mainly shows both temperature rise and smoke generation when a fire occurs, environmental sensors of the type of temperature sensor and smoke sensor may be provided around the power distribution apparatus (for example, in a fire risk area). These sensors may be used to monitor the status and environmental parameters of the power distribution equipment in real time, and for purposes of this description are collectively referred to herein as environmental sensors, and information output by the environmental sensors is collectively referred to as environmental sensing information.
In the fire monitoring system, the selected environment sensor can be arranged on the power distribution equipment to be monitored or around the equipment, so that the proper position of the environment sensor is ensured, and the related environment information of the equipment can be accurately acquired. The environment sensor can be connected with the main control equipment in a wired or wireless mode.
The first fire judgment result may include first event information determined according to the environmental sensing information, where the first event information may represent whether the power distribution device fires, and it should be noted that the first fire judgment result is a judgment result estimated according to the environmental sensing information, is not a final judgment result of the main control device, and further needs to be verified and judged in combination with the second fire judgment result.
S120, acquiring environment image information corresponding to each power distribution device from each camera device, and determining a second fire judgment result of each power distribution device according to each environment image information.
The environment image information corresponding to any power distribution equipment comprises the power distribution equipment and the image information of the fire risk area of the power distribution equipment.
The image pickup apparatus may be a camera. The difference between the camera and the sensor is that:
1. the application fields are different: the camera is mainly used for acquiring static or dynamic images and video information, and the sensor is mainly used for monitoring parameters of objects and environments and is applied to the fields of measurement, control, monitoring, automation and the like. 2. The principle is different: the principle of a camera is to convert an optical image into an electrical signal, while the principle of a sensor is to convert a physical feature into an electrical signal.
The mounting positions and the number of cameras can be set according to the positions of the power distribution devices. Specifically, the camera may be installed near or inside the power distribution device, as long as the image information of the fire risk area can be acquired. The camera can capture real-time images of the power distribution equipment, and the image information collected by the same type of camera equipment equipped for the power distribution equipment can cover the fire risk area of the power distribution equipment. Since the power distribution device mainly has two aspects of temperature rise and smoke generation when a fire disaster occurs, the image pickup device can comprise a common optical camera and an infrared camera. The infrared camera can acquire infrared images near the power distribution equipment, and mainly aims at a fire risk area, the infrared camera can be arranged in the fire risk area of the power distribution equipment; the general optical camera needs to collect the whole view of the whole fire risk area, so that the optical camera can be installed outside the fire risk area and is not easy to fire.
The sensor and the camera can be set according to the importance of the distribution equipment or the vulnerability of the device. For example, for power distribution equipment such as transformers, the importance is higher, and a plurality of sensors can be correspondingly arranged to ensure acquisition of environment sensing information of a plurality of types, and a plurality of cameras are correspondingly arranged to ensure omnibearing monitoring of a plurality of angles. In the case where each environmental sensor and each image pickup apparatus are provided, the main control apparatus can start executing the fire monitoring method. Each environmental sensor and each camera device can periodically or continuously collect data and transmit the data to the master control device.
The second fire judgment result may include second accident information determined according to the environmental image information, where the second accident information may represent whether the power distribution device fires, and it should be noted that the second fire judgment result is a judgment result estimated according to the environmental image information, is not a final judgment result of the main control device, and needs to be further verified and judged in combination with the first fire judgment result.
And S130, if the first fire judgment result and the second fire judgment result of any power distribution equipment indicate that the power distribution equipment fires, judging that the power distribution equipment is the fire equipment and giving fire alarm.
When the first fire disaster judgment result and the second fire disaster judgment result of a certain power distribution device indicate that the power distribution device fires, the first fire disaster judgment result and the second fire disaster judgment result indicate that the power distribution device fires through double verification of the environment sensor and the camera equipment, and the first fire disaster judgment result and the second fire disaster judgment result indicate that the power distribution device fires. When one of the first fire judgment result and the second fire judgment result of a certain power distribution device indicates that the device is on fire, it is insufficient to prove that the power distribution device is actually on fire. For example, when a person draws smoke beside the power distribution equipment, smoke can be identified based on the smoke sensor, but the infrared camera does not detect the temperature rise of the power distribution equipment, and at the moment, the situation that a fire disaster occurs can be judged through the environment image information and the environment sensing information. Based on the method, the fire misjudgment probability can be effectively reduced, and unnecessary personnel and material mobilization is avoided.
The main control equipment is also connected with alarm equipment, and can issue a fire alarm instruction when the power distribution equipment is judged to be fire equipment so as to control the alarm equipment to alarm in a sound, light, text and other modes, so that operation and maintenance personnel can be prompted to timely conduct fire processing.
According to the fire monitoring method of the power system, provided by the embodiment of the invention, whether the power distribution equipment fires or not is determined based on the double information by acquiring the environment sensing information acquired by the environment sensor and the environment image information acquired by the image pickup equipment, the confidence of the judgment result of the fire occurrence can be improved, the fire is judged by combining the double information, and the misjudgment can be effectively reduced. And moreover, each environment sensor and each camera equipment can conveniently collect relevant environment information on site, and the main control equipment can also acquire relevant environment information at any time and judge whether a fire disaster occurs or not, so that the equipment operation environment does not need to be checked manually and regularly, time and labor are saved, and the maintenance efficiency is high. The environment sensor and the camera equipment acquire information to automatically judge, so that risk investigation can be performed in real time, and timely warning can be performed when the power distribution equipment is on fire, thereby avoiding the potential safety hazard caused by loopholes generated in operation and maintenance of the power system by manual inspection, improving the use safety of the power distribution equipment and effectively improving the operation safety of the power system.
On the basis of the above embodiments, optionally, if one of the first fire disaster judgment result and the second fire disaster judgment result of any power distribution device indicates that the power distribution device is on fire, a fire check alarm is performed to remind a worker to check the safety of the power distribution device in time, and if a fire problem or risk is found, even if the processing is performed. If the first fire judgment result and the second fire judgment result of any power distribution equipment indicate that the power distribution equipment does not fire, the power distribution equipment can be judged to not fire, and the fire cannot be caused.
On the basis of the above embodiments, optionally, the first fire judgment result includes first accident information and first coordinate information of the power distribution apparatus.
Specifically, for each environmental sensor provided in the fire monitoring system, the coordinates thereof may be configured in advance and stored in the main control device. The main control device may determine first coordinate information in the first fire judgment result according to coordinates of the environmental sensor, and determine first incident information according to a specific physical characteristic value in the environmental sensing information. For example, the master control device may determine, according to the information source interface, coordinates of an environmental sensor connected to the interface, or coordinate information of the environmental sensor may be carried in the environmental sensing information, and transmit the coordinate information and the physical characteristic value to the master control device. If a plurality of power distribution devices exist in the power system, the coordinates of different environment sensors corresponding to different power distribution devices are different. If each power distribution device is configured with a plurality of (e.g., 2-3) environment sensors, the coordinates of all environment sensors corresponding to the same power distribution device are configured to be the same coordinates (e.g., the same coordinates as the power distribution device), so that the master control device can quickly locate the power distribution device with a possible fire accident according to the coordinates.
Similarly, the second fire judgment result includes second accident information and second coordinate information of the power distribution equipment.
Specifically, for each image pickup apparatus equipped in the fire monitoring system, coordinates thereof may be configured in advance and stored in the main control apparatus. The main control device can determine second coordinate information in a second fire judgment result according to coordinates of the image pickup device, and determine second accident information according to specific image features in the environment image information. For example, the master control device may determine the coordinates of the image capturing device connected to the interface according to the information source interface, or the coordinates of the image capturing device may be carried in the environmental image information, and transmit the coordinates and the image features to the master control device. If a plurality of power distribution devices exist in the power system, coordinates of different image pickup devices corresponding to different power distribution devices are different. If each power distribution device is provided with a plurality of (e.g. 2-3) image capturing devices, the coordinates of all the image capturing devices corresponding to the same power distribution device are configured to be the same coordinates, so that the main control device can quickly locate the power distribution device with possible fire accidents according to the coordinates. And the coordinates of all the image pickup devices and the coordinates of all the environment sensors corresponding to the same power distribution device are configured to be the same coordinates, so that the main control device can match and mutually check each first fire judgment result and each second fire judgment result.
If the first coordinate information in a certain first fire judgment result is consistent with the second coordinate information in a certain second fire judgment result, the first fire judgment result and the second fire judgment result can be judged to belong to the same power distribution equipment. And for the same power distribution equipment, if the first accident information in the first fire judgment result indicates that the power distribution equipment fires and the second accident information in the second fire judgment result indicates that the power distribution equipment fires, judging that the power distribution equipment is the fire equipment and giving fire alarm. Thus, the main control equipment can perform equipment positioning according to the coordinate information and judge whether the equipment fires according to the accident information.
The fire monitoring system is also provided with a monitoring screen, the monitoring screen is arranged in a monitoring room where a worker is located, and the main control equipment can be connected with the monitoring screen and control the monitoring screen to display detection results in real time, so that the visualization of the fire monitoring results is realized.
Then, the first accident information and the second accident information both indicate the power distribution equipment on which the equipment fires, the main control equipment can determine that the power distribution equipment is the fire equipment, generate a fire alarm instruction based on the first coordinate information (or the second coordinate information) corresponding to the fire equipment, and send the fire alarm instruction to the monitoring room so as to request to process the fire, wherein the fire alarm instruction can comprise the coordinate information of the power distribution equipment, and at the moment, the staff can quickly go to the power distribution equipment corresponding to the coordinate to perform fire extinguishing treatment.
For a power distribution device indicating that one of the first accident information and the second accident information is on fire, the master control device may generate a fire checking instruction based on the first coordinate information (or the second coordinate information) and send the fire checking instruction to the monitoring room to request information checking and processing, wherein the fire checking instruction may include the coordinate information of the power distribution device. Therefore, the staff can be reminded to observe the safety of the power distribution equipment in a manual checking reminding mode.
The monitoring screen is provided with display areas corresponding to all the power distribution equipment, and when a certain power distribution equipment is confirmed to be on fire, the display area corresponding to the power distribution equipment can be changed into red; when the condition of a certain power distribution device needs to be checked manually, the display area corresponding to the power distribution device can be changed into yellow. And the image and the environment sensing information of the area where the power distribution equipment is located can be displayed at the same time during alarming, and corresponding alarming sounds can be configured to attract the attention of staff.
On the basis of the above embodiments, optionally, the environmental sensor corresponding to the same power distribution device includes: at least one temperature sensor and at least one smoke sensor. When a fire disaster occurs in a certain power distribution device, smoke and the ambient temperature rise can be generated, and whether the fire disaster is possible to occur in the power distribution device can be judged through the temperature sensor and the smoke sensor. Specifically, as for the temperature, if the temperature exceeds a preset temperature, a fire may occur; the preset temperatures corresponding to different power distribution equipment can be the same or different, and the preset temperatures are specifically set according to actual conditions. For smoke, if the smoke concentration exceeds the preset concentration, a fire may occur; the preset concentrations corresponding to different power distribution equipment can be the same or different, and the preset concentrations are specifically set according to actual conditions.
Correspondingly, the step S110 may specifically include: for any power distribution device:
acquiring environment sensing information output by each temperature sensor and each smoke sensor corresponding to the power distribution equipment;
and if the environmental sensing information output by the at least one temperature sensor indicates that the environmental temperature exceeds the preset temperature and/or the environmental sensing information output by the at least one smoke sensor indicates that the smoke concentration exceeds the preset concentration, controlling the first fire judgment result of the power distribution equipment to indicate that the power distribution equipment fires, and particularly controlling the first accident information to indicate that the power distribution equipment fires.
On the basis of the above embodiments, optionally, the image capturing apparatus corresponding to the same power distribution apparatus includes: at least one optical camera and at least one infrared camera. Illustratively, where several environmental sensors are provided, it is desirable that the environmental image information include several types of sub-features for mutual authentication. For example, a temperature sensor and a smoke sensor are provided, and the present solution also needs to be able to analyze the characteristics of these 2 kinds of information from the environmental image information. For the temperature information, the camera equipment can be an infrared camera, and is used for collecting infrared images, and the infrared images can reflect the temperature information; for smoke, the camera may be a general optical camera to reduce the cost of the image capturing apparatus. The number of each camera can be set according to actual requirements. For example, one infrared camera and one optical camera may be provided. Specifically, the processing of the environmental image information may be performed by a trained temperature recognition model and a smoke recognition model (which may also be the same model) stored by the master device. If the model is 2 models, the environment image information shot by the infrared camera is input into the temperature recognition model, and the environment image information shot by the optical camera is input into the smoke recognition model.
Correspondingly, the step S120 may specifically include: for any power distribution device:
acquiring environment image information output by each optical camera and each infrared camera corresponding to the power distribution equipment;
recognizing environmental image information output by the infrared camera based on the temperature recognition model, and recognizing environmental image information output by the optical camera based on the smoke recognition model; and if the identification result of the environmental image information output by the at least one infrared camera is that the environmental temperature exceeds the preset temperature, and/or the identification result of the environmental image information output by the at least one optical camera is that the smoke concentration exceeds the preset concentration, controlling a second fire judgment result of the power distribution equipment to indicate that the power distribution equipment fires, and particularly controlling the second accident information to indicate that the power distribution equipment fires.
In summary, according to the fire monitoring method provided by the embodiment of the invention, the data collected by the environmental sensor and the image collected by the camera equipment are transmitted to the main control equipment for processing and analysis. The main control equipment uses a data analysis algorithm and an image processing technology to read the data and the image and extract key information. For example, a status, anomaly, or fault of the power distribution device may be detected by an image recognition algorithm.
The main control equipment gives an alarm and feeds back: and judging that the power distribution equipment normally operates or abnormal conditions exist according to the data and the image analysis result. If an anomaly is found, an alarm mechanism may be triggered to alert to notify the relevant personnel. Meanwhile, real-time equipment state feedback can be provided so as to take measures to repair equipment or adjust operation parameters in time.
And the fire monitoring system can also provide a remote monitoring function, so that a user can remotely access the main control equipment through network connection. Thus, the user can monitor the state of the power distribution equipment at any time and any place and take necessary measures in time.
In a word, through combining environmental sensor and camera equipment to monitor, can realize the comprehensive control and the real-time feedback of distribution equipment in the electric power system. The method can improve the reliability, the safety and the operation efficiency of the power distribution equipment, and timely discover and solve the fire conditions caused by faults or anomalies of the power distribution equipment.
Alternatively, the temperature recognition model and the smoke recognition model may be trained by the same model training method. The model training method comprises the following steps:
acquiring an image set comprising a plurality of training images; the training image comprises a designated style, and if the model to be trained is a temperature identification model, the designated style is the image style when the ambient temperature exceeds the preset temperature; if the model to be trained is a smoke recognition model, designating the style as an image style when the smoke concentration exceeds the preset concentration; if the temperature recognition model and the smoke recognition model adopt a unified model, the training image simultaneously contains the two specified styles.
Labeling each training image in the image set with first labeling information; the first annotation information comprises a first fire area and a first identification probability. The first labeling information can be labeled according to the actual fire related area in the training image, which is equivalent to the preprocessing process of the training image, and can be used as a standard reference label for comparing with the model output result.
Extracting a training image and inputting the training image into the model to be trained to obtain second labeling information of the training image; the second labeling information comprises a second fire region and a second identification probability.
And calculating the similarity of the first labeling information and the second labeling information of the same training image.
Judging whether the similarity is larger than a preset similarity threshold value or not; if yes, determining that training of the model to be trained is completed, and storing the model in the main control equipment; if not, adjusting parameters of the model to be trained based on the similarity, and returning to execute the step of extracting a training image to be input into the model to be trained to obtain second labeling information of the training image until training is completed; the training images extracted after the return can be randomly selected from the image set.
On the basis of the above embodiments, alternatively, a fire image of the power distribution apparatus in the power system in the fire environment may be directly photographed as a training image, and a large number of training images may be photographed as an image set.
If the scene images of various distribution equipment when a fire disaster occurs are difficult to collect during model training, images in different styles can be set through style migration, so that training images can be obtained. Specifically, the step of acquiring an image set including a plurality of training images may include:
acquiring a first preset number of original images of power distribution equipment in a power system to be monitored in a normal environment; the original soil phase is obtained through real shooting.
Acquiring fire images of a second preset number of other power distribution equipment except the power system in a fire environment; wherein the fire image may be obtained from the internet or from other sources.
And learning the image style in each fire image to obtain the target image style.
And migrating the style of the target image into each original image to obtain a first preset number of training images as an image set.
Illustratively, the first predetermined number is any value in the range of 1000-10000; the second preset number may be several tens, for example 20.
Through a style migration mode, the style of the image containing the fire environment is migrated to a real original image acquired by various power distribution equipment in a power system to be monitored under a normal environment, and the image containing various fire environments can be conveniently and rapidly acquired as training data of the recognition model, so that the problem that the recognition model is difficult to acquire training images can be solved.
