The purpose of doing a good job in safety management is to implement the strategic policy of "safety production first" in the power industry, effectively organize and carry out anti-accidents and greatly reduce General accidents, create a long-term safe and accident-free, and lay a solid foundation for the economic benefits of the power industry.

In the safety management of power production, the safety of equipment operation of substations is a very important part. In recent years, with the development of science and technology, the inspection of equipment status of substations has gradually begun to be unmanned or reduce the investment of human resources. The methods mainly include the use of robot inspections and fixed cameras to monitor primary and secondary equipment. Video inspection check.

For example, the Chinese invention patent with the application number of 2018109249198 and the title of a method for identifying hidden dangers in a substation indoor environment and an inspection robot discloses a method for identifying hidden dangers in the indoor environment of a substation and a robot for inspecting the hidden dangers in the indoor environment of a substation. The inspection robot includes: A base, a drive wheel and a drive motor, the base is provided with a sensor mounting plate and a display, the sensor mounting plate is provided with an ambient temperature and humidity sensor, an ozone sensor, an anion sensor and a controller, the ambient temperature and humidity sensor and control The ozone sensor is electrically connected with the controller, the negative ion sensor is electrically connected with the controller, and the display is electrically connected with the controller. Although this scheme can patrol the substation indoors, and identify environmental hidden dangers. However, the mobile robot is difficult to adapt to the all-terrain environment and is only suitable for indoor use, and the main transformer equipment of the substation is installed outdoors. safety cannot be effectively guaranteed.

Another example is the Chinese invention patent with the application number of 2019103289162 and the title of the indoor substation inspection system, method, device and readable storage medium. It divides the equipment to be inspected into two categories, one using robots for inspection, and the other using fixed cameras Obtain images of fixed points to conduct inspections through video; although this solution combines robots and camera devices to inspect a larger range of substations, it is difficult for fixed cameras to face all the instruments to be monitored, and the edges of the camera range are prone to appear. The picture is distorted, which leads to inaccurate readings. If a large number of cameras are used to obtain images, the occurrence of errors can be reduced to a certain extent, but this will greatly increase the cost of inspection and image recognition processing. time.

Secondly, in the above-mentioned existing patents, there is no management and control of inbound personnel. In realizing unmanned inspection, reducing or even requiring no personnel on duty, the intelligent substation is also very important for personnel entry and exit management and station operation area management. Strict management and control of personnel can effectively prevent operators from carrying out irregular operations, thereby ensuring the safety of substations to a certain extent.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

It should be noted that like numerals and letters refer to like items in the following figures, so once an item is defined in one figure, it does not require further definition and explanation in subsequent figures.

In the description of the present invention, it should also be noted that, unless otherwise expressly specified and limited, the terms "arranged", "installed", "connected" and "connected" should be understood in a broad sense, for example, it may be a fixed The connection can also be a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be internal communication between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific situations.

In a first aspect, the present invention provides an intelligent security management and control method for a substation, as shown in FIG. 1 , including the following steps:

In step S1, an inspection task is acquired and executed. The inspection task includes a periodic inspection task and a continuous inspection task. When the inspection task is performed, the collected data is analyzed synchronously.

The periodic inspection task specifically includes: using a mobile inspection device to collect sound, smell and first image data of the area it moves through; the mobile inspection device includes an inspection robot placed indoors and/or a mobile inspection robot placed outdoors. Mobile image acquisition equipment.

It can be known that the inspection robot located indoors can navigate through fixed path markers, and can also use laser radar and other means for path planning and obstacle avoidance; when path markers are used for navigation, the path setting needs to go through the waiting Detect the panel area of the equipment, so that the inspection robot can collect the status image data of the equipment in the preset path; when using lidar and other means for path planning, the map information of the inspection area needs to be collected in advance and stored in the inspection area. In the robot, so that the inspection robot can perform path planning.

The movable image acquisition equipment placed outdoors moves through the slide rails erected inside and outside the substation, and its moving speed is controllable. Usually, the speed of its moving inspection is less than 1m/s. In order to avoid affecting the normal operation of the substation, it is made of high-strength plastic, which can prevent the impact on the transformer equipment and high-voltage lines, and can also prevent the slider from sliding on the slide rail to generate sparks and affect the normal operation of the high-voltage line. ; In the slide rail made of high-strength plastic, it also includes a conductive cable, which is placed in the depression of the slide rail, which is equivalent to being half-covered by the slide rail, so as to avoid electric sparks and other effects on the substation. normal work. Secondly, the movable image acquisition device can also be set in the cable trench. It can be known that the cable trench lithium is also provided with slide rails for the movable image acquisition device to move, so as to realize the mobile monitoring of the cable trench, even if there are small Animal invasion can also find its specific location in time.

Of course, whether it is an inspection robot or a movable image acquisition device in the mobile inspection device, its function is not only to collect the status image information of the equipment in the substation, but also to collect the sound information of the operation of the equipment and the smell information in the substation. When the transformer equipment and other equipment of the substation are in an abnormal state, the sound of the operation of the equipment usually changes. This method collects the sound information of the equipment operation, and obtains the frequency spectrum of the collected sound information. The spectrum corresponding to the abnormality stored in advance is compared to obtain the approximate type of the abnormality and store it. The abnormal type is verified and recorded during the operation and maintenance of the operation and maintenance personnel, so that the data record can be recorded for a long time and the record is more accurate. The abnormal corresponding spectrum information or the abnormal corresponding spectrum information is corrected.

Since the equipment in the substation will generate high temperature in most abnormal states, the high temperature will cause the corresponding plastic parts to burn to produce one or more odors or odor molecules. The mobile inspection device is assisted by the collection of odor or odor molecules. Determine whether the corresponding equipment in the substation is abnormal; when it can be known, the collection of odors or odor molecules in this method is only for one or several specific odors, such as the odor of the burning plastic parts or rubber parts used in the substation.

The continuous inspection task specifically includes: using a fixed inspection device to collect second image data; the fixed inspection device includes multiple 360-degree panoramic camera devices and multiple wide-angle camera devices; in this embodiment, the 360-degree panoramic camera device includes two , the selection of the number depends on the area of the substation, usually two need to be set, which are mainly used to collect the panorama of the substation and monitor the situation in the substation in real time. Recognize moving objects in images; wide-angle camera devices are mainly supplements to mobile inspection devices. Due to the complex environment in substations, it is difficult for mobile inspection devices to collect image information in certain areas, or to install mobile inspection devices in certain areas. When the required track will greatly increase the cost or reduce the stability, a wide-angle camera device is used to supplement it, such as the entrance and exit of the cable trench or the equipment in the area where the slide rail does not pass, etc. At the same time, the wide-angle camera device will also be installed. At the entrance and exit of the substation, the image information of the people entering and leaving is collected.

Wherein, identifying and analyzing the collected data synchronously in step S1 includes that the monitoring center identifies and analyzes the first and second image data in the collected data through image recognition technology, wherein the first and second image data both include Visible light images and infrared images, infrared images are mainly used to obtain equipment temperature information in the collection area, as well as sound data in the collected data through audio spectrum analysis as described above, and pre-stored data to compare and analyze the odor data in the collected data.

In addition, before recognizing and analyzing the first and second image data in the collected data through the image recognition technology, the method further includes performing dynamic image perception on the first and second image data. If a dynamic image appears, it can be determined that there is a The moving object may be an invading small animal or other object. At this time, the specific type of the moving object in the dynamic picture is identified through image recognition technology, and it is judged whether it will affect the substation, and then the dynamic picture and the set If there is no dynamic picture, only the picture with the mark to be identified in the first and second image data will be recognized. It can be known that for the convenience of image recognition processing To obtain a faster processing speed, a mark to be identified can be set on the panel area of the device. The mark to be identified can be a mark that encloses the panel area to be identified, or can be set within the range of the panel area to be identified. For other marks, when the image recognition system recognizes the mark to be identified, the device panel or device shape in the corresponding screen will be identified. If the mark to be identified is not included in the image, no image recognition will be performed. By setting the mark to be identified, you can It saves a lot of time for image recognition processing, and then obtains abnormal information in an inspection task faster.

On the basis of detecting the dynamic changes of the picture, when the moving object in the dynamic picture is recognized as an animal, the sound and smell matching the animal will be released in the corresponding area to drive away; common small animals include snakes, mice , other wild animals or cats in nearby residences, etc., after determining the type of animal, play the pre-stored sounds of natural enemies of small animals or other sounds that can make the corresponding animals feel scared to drive them away. At the same time, it can also properly release the smell that causes the corresponding animal discomfort to further achieve the purpose of driving away small animals, thereby preventing small animals from invading the substation to carry out destructive activities or affecting the normal operation of the substation.

Step S2, if there is no abnormality in the data analysis in the inspection task, the continuous inspection task continues to be executed, and the periodic inspection task waits for the next execution cycle. Usually, the execution cycle of the periodic inspection task is 1-3 days; it needs to be explained here However, due to the constant video inspection, its image storage capacity will reach a very large scale. In order to save costs, the storage device adopts the method of cyclic coverage storage. The coverage period can be selected according to specific needs, but abnormality occurs. Image segments, image segments with dynamic pictures, and abnormal sound data will be permanently stored for big data analysis when there is a certain amount of data to assist in increasing the accuracy of the previous judgment model or image recognition model. If the data analysis is abnormal in the inspection task, step S3 is executed.

It should be noted that, for the judgment principle of abnormal image segment, image segment with dynamic picture, and abnormal sound, the method of image comparison and analysis can be used to determine abnormal image segment. One or more frames of images are compared and analyzed with one or more pre-recorded images under standard working conditions, so as to determine whether the real-time captured image segment is in an abnormal state. The image segments that are judged to be abnormal by intelligence are checked manually to ensure their accuracy; dynamic images mainly include images of animal invasion, equipment shaking caused by geological disasters, or abnormal equipment displacement caused by manual operation and maintenance, etc. , adopts the method of dynamic monitoring on the screen. When there are people in the screen, the main body of monitoring is the related equipment of the substation, reducing the impact of the movement of the operation and maintenance personnel on the monitoring results; for the monitoring of sound, the sound spectrum can be used. The sound spectrum can obtain the vibration frequency of the sound produced by the operation of the substation equipment. When the vibration frequency is in an abnormal state, such as the vibration frequency is too high or too low, it is judged as an abnormal sound.

In step S3, the abnormal information and the corresponding collected raw data are sent to the monitoring center, and the monitoring center determines the abnormal area and plans the operation and maintenance operation area and personnel entry route, and plans according to the abnormal area and the estimated abnormal type in advance. The operation and maintenance operation area and the route to enter the operation area, because in the event of an abnormality, there may be potential safety hazards, and rashly entering the operation area may cause accidental injury, so the operation and maintenance personnel need to enter the operation and maintenance area according to the prescribed route, and can only Operate in the planned operation and maintenance area to prevent damage to the equipment in the non-operation and maintenance area or affect the operation of the equipment in the corresponding area; it can be seen that planning the operation and maintenance operation area and the entry route of personnel can ensure the safety of operation and maintenance personnel, and also Standardize the operation and maintenance operations of the operation and maintenance personnel to avoid misoperation affecting the operation of the substation; and then send the personnel entry route and operation and maintenance operation area information to the mobile terminal with a unique number; the mobile terminal can be assigned operation and maintenance tasks by the operation and maintenance personnel. Obtain and hold the mobile terminal to perform operation and maintenance, or the mobile terminal may be a mobile terminal device held by the corresponding personnel.

In step S3, the monitoring center determines the area where the abnormality occurs and plans the operation and maintenance work area and the personnel entering the route. The monitoring center also checks the first image data judged to be abnormal. If the judgment is inaccurate, skip to step S1 ; If the judgment is accurate, continue to perform step S3, send personnel entry route and operation and maintenance operation area information to the mobile terminal with a unique number, allocate operation and maintenance tasks, and the operation and maintenance personnel will carry out the operation and maintenance on the mobile terminal.

Since the first image data is obtained by the mobile inspection device, blurring or other influences may occur during the moving process. Therefore, the first image data judged to be abnormal can be manually reviewed to ensure the accuracy of image recognition. Avoid the time loss of operation and maintenance personnel due to abnormal judgment errors.

In step S4, the identity of the operation and maintenance personnel is verified by identifying whether the mobile terminal that has received the entry route and the operation and maintenance operation area is held, and if so, the operation and maintenance personnel are released for operation and maintenance. In order to receive the mobile terminal of the entry route and the operation and maintenance operation area, the judgment can be made; if not, the identity of the personnel shall be further verified. If the identity of the personnel is normal, that is, the personnel are in the establishment of the substation, the personnel shall be entered into the route and the operation and maintenance operation area. Send it to the mobile terminal held by the person. If the identity of the person is not a person in the substation, an alarm will be sent to the monitoring center for further processing, and the operation and maintenance tasks will be reassigned.

In step S4, when the mobile terminal enters the substation, the camera is turned on, and the third image data is collected and sent to the monitoring center. Acknowledge the message, and raise an alarm if there is no response.

It should be noted that the mobile terminal can be fixed on the tooling or safety helmet of the operation and maintenance personnel through the clamping device, so that the third image data of the first-person perspective of the operation and maintenance personnel can be obtained. Due to its fixed position, it is difficult to Keep an absolute static state, so the third image data is checked for static screen. When the screen is static for longer than the preset value, a confirmation message will be sent to the mobile terminal. If there is no response, the operation and maintenance personnel will be in a coma, and an alarm will be issued at this time. , to remind the operation and maintenance personnel of the rescue operation.

At the same time, in step S4, when the mobile terminal enters the substation, the positioning function is also enabled, including satellite positioning and/or radio frequency identification positioning. When the mobile terminal is in the area, record and continue to send sound warnings until the mobile terminal is in the area of personnel entry route and operation and maintenance operation area.
