and step S3, identifying violation operations of the user in the real-time image, and generating an early warning signal, wherein the violation operations comprise a safety tool wearing violation of a worker, a position violation of the visitor, and an unlocking operation violation of a non-work authority person.

In some optional embodiments, the acquiring a real-time image of the monitoring area of the distribution room comprises:

step S11, images shot by at least two panoramic cameras installed in the power distribution room are obtained;

and step S12, synthesizing the images to obtain a three-dimensional panoramic monitoring image.

In this application, at first select the power distribution station suitable position installation two to three panoramic camera to form the panorama control to the electricity distribution room, for example install two 360 degrees cameras, set up respectively at the both ends in power distribution station corridor, wherein the both sides in corridor in a plurality of rack settings are in the power distribution station.

The system hardware mainly comprises a panoramic camera, a video coding server, an operator safety tool analysis server and an alarm device. The video acquisition camera system, the video server and the alarm device can use the existing equipment system in the power distribution station. The server of the early warning system needs to be provided with a high-performance neural network computing unit for supporting an intelligent monitoring function.

In step S2, relevant person information is entered first, and information is entered for workers who can operate the distribution substation equipment and for other persons who cannot operate the equipment but have authority to monitor, and the user appearing in the monitoring screen is deeply learned by using the face recognition technology based on deep learning, so that the two persons can be recognized and the other persons can be identified as visitors.

It should be noted that, the deep learning for face recognition may also be used to establish a user library, and the staff in the user library has its operating right for a specific device bound, for example, the user a has an operating right for the device a, the user B has an operating right for the device B, and the user C has an operating right for both the device a and the device B, so that when generating the alarm information in step S3, even for the staff, the alarm information is generated for the staff who exceed the operating right (for example, the user B operates the device a).

In the above embodiment, in step S3, an object recognition technique based on deep learning is also adopted, so as to implement a function of recognizing a safety tool through a video image, and achieve an early warning purpose of wearing the safety tool for a worker.

In step S3, the image information of the operator is captured by the panoramic camera, and the carrying condition of the safety tool of the operator is monitored by using an image-based detection and analysis method. And giving early warning prompt according to the actual regulation and regulation.

In some optional embodiments, the generating the warning signal comprises:

step S31, calling a corresponding prompt in a database according to the violation operation type of the user, and sending the prompt to the user;

and step S32, rendering and presenting the illegal operation user at the monitoring end.

s321, performing linkage real-time rendering presentation on the same violation operation user in the images acquired by the multiple paths of cameras;

and S322, splicing the newly rendered videos through a splicing algorithm to obtain rendering presentation in the three-dimensional panoramic monitoring image.

It can be understood that the video is rendered in real time and early-warned to obtain the videos in the multiple paths of cameras, and when early-warning information occurs, the real-time rendering warning module is linked to present in the video in the paths, so that the digital twin effect is achieved. For each path of video after re-rendering, each path of video can be spliced through an efficient splicing algorithm, so that the early warning effect in the panoramic video is achieved.

In some optional embodiments, identifying the violating actions of the user in the real-time image comprises:

for the staff, marking human key points according to the real-time image, and determining whether corresponding safety tools exist at each human key point which is to be worn with the safety tools;

for the visitors, determining the distance between the position of the user and the warning line, and determining whether the user crosses the warning line;

and for the non-worker authority personnel, determining whether the non-worker authority personnel unlock the equipment without the operation authority.

For example, when a worker enters, two aspects of monitoring are mainly included, one is identity authentication, and the other is violation authentication, for identity authentication, the system firstly determines the identity of the worker, obtains the access right of the worker through the database, and comprises which devices can be operated and which devices cannot be operated, namely determines the access level of the worker relative to the devices, and for non-operated devices, the worker can be classified as a non-worker-authority person or a visiting person. For operable equipment, it is a worker.

For violation identification, since the violation identification belongs to the staff, whether the corresponding safety tool exists at each key point of the human body which should wear the safety tool is determined, for example, if the worker finds that the worker does not wear the work clothes through image recognition, the sound in the warning voice database can be called to prompt the related staff. For example, the alert and warning phrase may be:

and (3) warning of dressing irregularity of workers: "the work dressing is not standardized, please check the safety helmet"; "the work dressing is not standardized, please check the insulating gloves"; "the dress is not standard in the work, please check the insulating shoes"; "dressing is not standardized, please check cotton uniform".

It will be appreciated that no reminder is given to the visitor.

In another embodiment, a worker may enter the work area and a visitor may enter the substation, but the feet cannot touch the fence and the hands cannot touch the equipment. Reminding and early warning terms are as follows:

early warning of non-work order authority personnel: "unauthorized person, Do not unlock operation"; the work order authority personnel remind: "go to next step"; early warning for visitors: "you have crossed the warning line, please go back"; "dangerous behavior, do not need to approach" and no warning is given to the staff.

It can be understood that the method is applied to the server side, the device for reminding the user can be a handheld terminal of the user or a device installed in the distribution station, if the device is the handheld terminal of the user, the terminals installed at different devices of the distribution station need to be recorded, the server side is provided with a terminal list, and after illegal operations of different distribution station devices are detected, the called alarm information can be accurately sent to alarm terminals of different distribution station devices. In addition, the application also has a monitoring end, which comprises a plurality of monitoring devices which are installed in the monitoring room and can present a plurality of monitoring pictures, and can also comprise a handheld monitoring end, wherein the handheld monitoring end can be a 3D monitoring picture, for example, desktop software which is installed on a mobile phone and supports 3D panoramic playing is installed, so that the immersive playing of the panoramic video in the terminal is ensured. The software supports seamless switching of the plurality of panoramic cameras, and realizes a mode of switching similar scenes, so that the effect of freely switching similar roaming of the plurality of panoramic cameras is ensured.

In order to ensure the transmission performance of video or images, the method adopts

(1) The real-time stream forwarding technology ensures short playing delay of the panoramic video.

(2) The video coding and decoding compression and the effective video coding compression can greatly relieve the pressure on the bandwidth, thereby reducing the dependence on hardware equipment and greatly accelerating the transmission speed.

(3) The video is encrypted, and in the transmission process, in order to prevent the possible problems of monitoring and the like, the panoramic video is encrypted, so that the absolute safety in the transmission process of the panoramic video is ensured.
