In a first aspect, the present invention provides a method for intelligently and safely managing and controlling a substation, as shown in fig. 1, including the following steps:
and step S1, acquiring and executing the inspection task, wherein the inspection task comprises a periodic inspection task and a continuous inspection task, and the acquired data is synchronously analyzed when the inspection task is executed.
The periodic inspection task specifically comprises the steps of collecting sound, smell and first image data of an area where the mobile inspection device moves through by using the mobile inspection device; the mobile inspection device comprises an inspection robot arranged indoors and/or a mobile image acquisition device arranged outdoors.
As can be known, the inspection robot located indoors can navigate through a fixed path mark, and can also plan a path and avoid obstacles through means such as a laser radar; when the route mark is adopted for navigation, the setting of the route needs to pass through a panel area of the equipment to be detected, so that the inspection robot can acquire state image data of the equipment in a preset route; when the route planning is performed by means of laser radar and the like, the map information of the inspection area needs to be collected in advance and stored in the inspection robot, so that the inspection robot can perform the route planning.
The movable image acquisition equipment is arranged outdoors, the moving speed of the movable image acquisition equipment is controllable, the moving inspection speed of the movable image acquisition equipment is usually less than 1m/s, and the sliding rail is erected between densely distributed high-voltage lines, so that the normal work of the transformer substation is avoided being influenced; in the slide rail made of the high-strength plastic, the high-strength plastic also comprises a conductive cable, and the conductive cable is arranged in the recess of the slide rail and is equivalently half-coated by the slide rail, so that the influence of electric sparks and the like on the normal work of a transformer substation is avoided. Secondly this portable image acquisition equipment can also set up in the cable pit, can know that the cable pit lithium also is provided with the slide rail and supplies portable image acquisition equipment to remove this moment to the realization is to the removal control of cable pit, even there is the toy invasion also can in time discover its specific position.
Of course, whether the mobile inspection device is an inspection robot or a mobile image acquisition device, the mobile inspection device not only has the function of acquiring the state image information of equipment in the transformer substation, but also is used for acquiring the sound information of equipment operation and the smell information in the transformer substation, when the transformation equipment and other equipment of the transformer substation are in abnormal states, the sound of the equipment operation is usually changed, the method acquires the frequency spectrum of the acquired sound information by acquiring the sound information of the equipment operation, by comparing the acquired sound frequency spectrum information with the frequency spectrum corresponding to the abnormality stored in advance, the approximate type of the abnormality is acquired and stored, the abnormal type is verified and recorded when the operation and maintenance personnel operate and maintain, so that data records for a long time can be sung, more accurate frequency spectrum information corresponding to the abnormality is recorded or corrected.
The equipment in the transformer substation generates high temperature in most abnormal states, the high temperature can cause corresponding plastic parts to burn so as to generate one or more kinds of smell or smell molecules, and the mobile inspection device assists in judging whether the corresponding equipment in the transformer substation is abnormal or not through collecting the smell or the smell molecules; it is known that the collection of the odor or odor molecules in the method is only specific to one or several odors, such as the odor of burning plastic or rubber parts used in the substation.
The continuous inspection task specifically comprises the steps of acquiring second image data by using a fixed inspection device; the fixed inspection device comprises a plurality of 360-degree panoramic camera devices and a plurality of wide-angle camera devices; the 360-degree panoramic camera device is mainly used for acquiring a panoramic image of the transformer substation, monitoring the conditions in the transformer substation in real time, and identifying objects moving by the acquired image in a dynamic sensing manner; the wide-angle camera device is mainly used for supplementing the mobile inspection device, the environment in the transformer substation is complex, the mobile inspection device is difficult to acquire image information of certain regions, or the mobile inspection device and a required track thereof are arranged in certain regions, so that the cost is greatly increased or the stability is reduced, the wide-angle camera device is adopted for supplementing, for example, the entrance and exit of a cable duct or the equipment where a slide rail does not pass through the region are arranged, and meanwhile, the wide-angle camera device can also be installed at the entrance and exit of the transformer substation, and the image information of people who enter and exit is acquired.
The step S1 of synchronously recognizing and analyzing the collected data includes that the monitoring center recognizes and analyzes the first and second image data in the collected data through an image recognition technology, where the first and second image data include both visible light images and infrared images, the infrared images are mainly used to obtain the device temperature information of the collection area, and analyze the sound data in the collected data through audio frequency spectrum analysis as described above, and compare and analyze the odor data in the collected data through pre-stored data.
In addition, before the first image data and the second image data in the acquired data are identified and analyzed through the image identification technology, the image dynamic perception is carried out on the first image data and the second image data, if a dynamic image appears, a moving object, which may be an invasive small animal or other objects, can be judged in the image, at the moment, the specific type of the moving object in the dynamic image is identified through the image identification technology, whether the moving object affects a transformer substation is judged, and then the dynamic image and the type of the identified moving object are stored, so that a worker can conveniently review and confirm the moving object; if no dynamic picture appears, only pictures with marks to be identified in the first and second image data are identified, it can be known that, in order to obtain a faster processing speed during image identification processing, marks to be identified can be set on a panel area of the device, the marks to be identified can be marks framing a panel area to be identified, or other marks set within the range of the panel area to be identified, when the image identification system identifies the marks to be identified, the device panel or the device shape in the corresponding picture is identified, if the image does not include the marks to be identified, image identification is not performed, and through the setting of the marks to be identified, the time for image identification processing can be greatly saved, and then abnormal information in the polling task can be obtained more quickly.
On the basis of detecting the dynamic change of the picture, when the moving object in the dynamic picture is identified to be an animal, releasing the sound and the smell matched with the animal in the corresponding area for driving away; after the type of the animal is determined, the sound of the natural enemy of the small animal stored in advance or other sounds which can make the corresponding animal feel feared are played to expel the animal, and the unpleasant odor of the corresponding animal can be properly released while the sound is expelled so as to further achieve the purpose of expelling the small animal, so that the small animal is prevented from invading the transformer substation to destroy the activity or influence the normal operation of the transformer substation.
Step S2, if the data analysis is not abnormal in the polling task, the polling task is continuously executed, the periodic polling task waits for the next execution period, and the execution period of the periodic polling task is usually 1-3 days; it should be noted here that, since video inspection is performed at any time, the image storage capacity of the storage device will reach a very large scale, and in order to save cost, the storage device adopts a cyclic coverage storage mode, and the coverage period of the storage device can be selected according to specific requirements, but abnormal image segments, image segments with dynamic pictures, and abnormal sound data are all stored permanently, so that the data can be subjected to big data analysis when the data has a certain amount, and the big data analysis is used for assisting in increasing the accuracy of a prior judgment model or an image recognition model; then, if the data analysis is abnormal in the inspection task, step S3 is executed.
It should be noted that, the determination of the abnormal image segment, the image segment with a dynamic picture, and the abnormal sound may adopt an image contrast analysis method, and a certain frame or multiple frames of images in a certain image segment collected in real time are compared with one or more images recorded in advance under a standard working state, so as to determine whether the image segment collected in real time is in an abnormal state, and it is known that, in order to make the determination result more accurate, the image segment intelligently determined as abnormal may be manually verified to ensure the accuracy thereof; the dynamic picture mainly comprises a picture invaded by animals, equipment shaking caused by disasters such as geology and the like or abnormal equipment displacement caused by manual operation and maintenance, and the like, and adopts a picture dynamic monitoring mode, and under the condition that people exist in the picture, a monitored main body is related equipment of a transformer substation, so that the influence of the movement of operation and maintenance personnel on a monitoring result is reduced; the method for monitoring the sound can adopt a sound spectrum mode to determine whether the sound is abnormal or not, the sound spectrum can acquire the vibration frequency of the sound emitted by the operation of the substation equipment, and when the vibration frequency is in an abnormal state, such as when the vibration frequency is too high or too low, the abnormal sound is determined.
Step S3, sending the abnormal information and the corresponding collected original data to a monitoring center, the monitoring center determining the area where the abnormality occurs and planning the operation area and the personnel entry route, planning the operation area and the personnel entry route according to the area where the abnormality occurs and the estimated abnormal type in advance, because potential safety hazards exist when the abnormality occurs, the operation area may be accidentally injured when the operation personnel enters the operation area, and the operation personnel is required to enter the operation area according to the specified route, and can only operate in the planned operation area at the same time, so as to prevent the equipment entering the non-operation area from being injured or affecting the operation of the corresponding area; therefore, the safety of operation and maintenance personnel can be ensured by planning an operation and maintenance operation area and personnel entry routes, the operation and maintenance operation of the operation and maintenance personnel can be standardized, and the influence of misoperation on the operation of a transformer substation is avoided; further sending the information of the personnel entering the route and the operation and maintenance operation area to a mobile terminal with a unique number; the mobile terminal may be obtained by operation and maintenance personnel by allocating operation and maintenance tasks and hold the mobile terminal to execute operation and maintenance, or the mobile terminal may be a mobile terminal device fixedly held by a corresponding personnel.
The monitoring center determines an area where the abnormality occurs and plans a transport and maintenance operation area and before the personnel enter the route in the step S3, the monitoring center rechecks the first image data which is judged to be abnormal, and if the judgment is not accurate, the monitoring center jumps to execute the step S1; if the judgment is accurate, the step S3 is continuously executed, the information of the personnel entry route and the operation and maintenance operation area is sent to the mobile terminal with the unique number, the operation and maintenance task is distributed, and the operation and maintenance personnel maintain the mobile terminal to execute the operation and maintenance.
Because the first image data is acquired by the mobile inspection device, the first image data which is judged to be abnormal can be manually rechecked due to the possibility of picture blurring or other influences in the moving process, so that the accuracy of image identification is ensured, and the time loss of operation and maintenance personnel caused by the error of abnormal judgment can be avoided.
Step S4, checking the identity of the operation and maintenance personnel by identifying whether the mobile terminal receiving the entering route and the operation and maintenance operation area holds, if so, releasing the operation and maintenance, and judging only by identifying whether the mobile terminal is the mobile terminal receiving the entering route and the operation and maintenance operation area because the mobile terminal has the unique representation code; if the personnel identity is not the same as the personnel identity in the substation, the personnel entering the route and the operation and maintenance operation area are sent to a mobile terminal held by the personnel, if the personnel identity is not the same as the personnel in the substation, an alarm is sent to a monitoring center for further processing by the monitoring center, and the operation and maintenance task is redistributed.
In step S4, when the mobile terminal enters the substation, camera shooting is started, third image data is collected and sent to the monitoring center, the monitoring center performs image static inspection on the third image data, when the image static duration exceeds a preset value, the monitoring center sends confirmation information to the mobile terminal, and if no response is given, an alarm is sent.
It should be noted that the mobile terminal can be fixed on a tool of an operation and maintenance worker or a safety helmet through the clamping device, so that third image data of a first person viewing angle of the operation and maintenance worker can be obtained, due to the fixed position of the mobile terminal, the third image data is difficult to keep in an absolute static state, image static inspection is performed on the third image data, when the static time of an image exceeds a preset value, confirmation information is sent to the mobile terminal, if no response is made, the operation and maintenance worker is in a coma state, at the moment, an alarm is sent out, and the operation and maintenance worker for rescue operation is reminded.
Meanwhile, in step S4, when the mobile terminal enters the substation, a positioning function is also activated, including positioning by satellite positioning and/or radio frequency identification, and when the position of the mobile terminal is not in the route area and the operation and maintenance area where the mobile terminal receives the personnel, recording is performed and a sound warning is continuously sent until the mobile terminal is in the route area and the operation and maintenance area where the personnel enter.
