Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example one

As shown in fig. 1, the method includes:
s110, when a video acquisition request is received, the power exchange station attribute information in the video acquisition request is determined.
It should be noted that, a camera device may be installed in the power exchanging station, and the power exchanging station is monitored in real time by the camera device, for example, when the camera is in an online state, a video stream acquired by the camera may be pulled to be live on a display screen of the visualization platform, so as to achieve the purpose of monitoring the state in real time.
In this embodiment, when it is detected that a control corresponding to the monitoring swapping station is triggered, it is considered that a video acquisition request is received, and the swapping station attribute information may be based on swapping station attribute information in the video acquisition request, and the swapping station attribute information may be basic information of the swapping station, so as to determine, based on the swapping station attribute information, which swapping station monitoring video stream needs to be pulled for playing.
Optionally, when the video acquisition request is received, determining the power swapping station attribute information in the video acquisition request includes: receiving a video acquisition request corresponding to a power swapping station; and analyzing the video acquisition request to obtain the charging station attribute information carried by the video acquisition request.
The video attribute information comprises an access token and a power swapping station identifier. The access token may be used to verify the identity of the requestor. The charging station identifier may be used to characterize the uniqueness of the charging station, for example, an identity document (id) of the charging station. Optionally, the video attribute information may include one power swapping station identifier, or may include multiple power swapping station identifiers. For example, if the video attribute information includes a power swapping station identifier, it may only be required to pull a video stream acquired by each camera in the power swapping station corresponding to the power swapping station identifier; if the video attribute information comprises a plurality of power station replacing identifications, the video stream collected by each camera in each power station corresponding to each power station replacing identification needs to be pulled, and at the moment, a plurality of power stations can be monitored simultaneously.
In this embodiment, when a video acquisition request corresponding to a swapping station is received, the video acquisition request may be analyzed to obtain an access token, a swapping station identifier, and the like carried in the video acquisition request, so as to determine whether a requester has a right to monitor the swapping station based on the access token, and determine which monitoring video streams of the swapping station need to be pulled for playing based on the swapping station identifier.
And S120, acquiring a target video stream address corresponding to the video acquisition request based on the power conversion station attribute information, and pulling a multimedia video stream for playing based on the target video stream address.
The target video stream address is spliced based on the live stream addresses of at least one camera device in the power conversion station.
In this embodiment, a target video stream address of the swapping station corresponding to the swapping station identifier may be obtained based on the swapping station identifier in the swapping station attribute information, and further, a multimedia video stream for monitoring the swapping station may be pulled based on the target video stream address and played. It should be noted that if there are multiple swapping station identifiers, there are multiple target video stream addresses corresponding to the swapping station identifiers, and the multimedia video streams corresponding to the swapping stations can be played.
It should be further noted that, in order to ensure the security of video monitoring, when the target video stream address corresponding to the video acquisition request is acquired based on the power swapping station attribute information, whether the requester has the right to monitor the power swapping station may be verified based on the access token in the power swapping station attribute information, and if yes, which monitoring video streams of the power swapping station need to be pulled for playing may be determined based on the power swapping station identifier.
Optionally, acquiring a target video stream address corresponding to the video acquisition request based on the swapping station attribute information includes: and if the access token is consistent with the temporary storage token, calling a target video stream address associated with the power swapping station identifier based on a preset mapping relation.
The preset mapping relationship may be a mapping relationship between the power swapping station identifier and the target video stream address.
In this embodiment, when it is detected that the access token is consistent with the temporary storage token, it is considered that the requester may further obtain the monitoring video, and at this time, the target video stream address associated with the swapping station identifier may be called by using a preset mapping relationship. For example, the target video stream address mapped with the swapping station site id may be obtained from the server according to the Access Token (Access Token) and the swapping station identifier (swapping station site id).
It should be noted that, in order to enhance the security of video monitoring, the temporary token may be updated periodically, for example, the period may be 7 days, and a new temporary token needs to be obtained again every 7 days, and it is verified whether the requester has the right to monitor the power swapping station based on the new temporary token.
Optionally, the method further includes: acquiring a temporary storage token based on a general security protocol; and when the obtaining duration of the temporary storage token reaches the preset duration, re-executing the operation of obtaining the temporary storage token to obtain a new access token, and re-using the new access token as the temporary storage token.
The universal security Protocol may be an https (Hyper Text Transfer Protocol over secure Layer) Protocol.
In this embodiment, the temporary storage token may be obtained by using a universal security protocol and stored in the database. When the obtaining time of the temporary storage token reaches the preset time (for example, the effective time is 7 days), the universal security protocol can be reused to obtain a new access token, and the new access token is used as the temporary storage token again to replace the previous temporary storage token stored in the database. For example, a user Access Token (Access Token) can be obtained according to an https protocol to be used as a temporary storage Token, the temporary storage Token is stored in a database, the time is 7 days, the interface judges whether the temporary storage Token is expired, and if the temporary storage Token is expired, the Access Token is obtained again to be used as a new temporary storage Token; if not, the current scratch token continues to be used.
It should be noted that before the target video stream address corresponding to the video acquisition request is acquired based on the power conversion station attribute information, the live stream address of at least one camera device in the power conversion station may be spliced to obtain the target video stream address capable of playing the monitoring video of the entire power conversion station. It should be noted that each camera may be of a different type, and accordingly, the protocol of the live streaming address of the access network is also different. In order to enable the monitoring videos of the camera devices of different models to be synchronously played on the display screen, format conversion processing can be performed on live streaming addresses of the camera devices when the camera devices are connected to a network, and the live streaming addresses capable of being synchronously played can be obtained.
Optionally, before acquiring the target video stream address corresponding to the video acquisition request based on the power swapping station attribute information, the method further includes: converting original live broadcast addresses of all the camera devices in the power conversion station based on a preset standard protocol to obtain live broadcast stream addresses corresponding to all the camera devices; splicing the live streaming addresses to obtain live streaming addresses to be encrypted corresponding to the power conversion station; and encrypting the live broadcast address to be encrypted to obtain a target video stream address corresponding to the power swapping station, and establishing a mapping relation based on the target video stream address and a power swapping station identifier of the power swapping station so as to call the target video stream address associated with the power swapping station identifier based on a preset mapping relation.
The original live broadcast address can be understood as a live broadcast stream address when the camera device is connected to a video monitoring network in a networking state.
In this embodiment, the original live broadcast addresses of the camera devices in a certain swapping station may be converted by using a preset standard protocol to obtain live broadcast stream addresses corresponding to the camera devices, where the protocols of the live broadcast stream addresses are all consistent. The live streaming addresses can be spliced to obtain a video streaming address corresponding to the power conversion station, namely a live streaming address to be encrypted. In order to improve monitoring security, an encryption algorithm can be used for encrypting the live broadcast address to be encrypted to obtain a target video stream address corresponding to the power swapping station, and a mapping relation between the target video stream address and a power swapping station identifier of the power swapping station can be established by using a mapping technology, so that the target video stream address associated with the power swapping station identifier can be called subsequently based on a preset mapping relation.
It should be noted that, when the multimedia video stream is pulled to be played based on the target video stream address, since the target video stream address is obtained by encrypting the live broadcast address to be encrypted, the target video stream address needs to be decrypted, and further, the decrypted video stream address can be pulled by using the program code to obtain the multimedia video stream to be played.
Optionally, pulling the multimedia video stream for playing based on the target video stream address, including: decrypting the target video stream address to obtain a video stream address to be embedded; embedding the video stream address to be embedded into a preset rendering program to generate a target rendering program; and pulling the multimedia video stream based on the target rendering program, and playing the multimedia video stream on the display screen.
In this embodiment, the decryption algorithm may be used to decrypt the target video stream address, so as to obtain a decrypted video stream address, which is used as the video stream address to be embedded. The address of the video stream to be embedded can be embedded into a preset rendering program to generate a target rendering program, the multimedia video stream can be pulled based on the target rendering program, for example, the multimedia video stream is embedded into a code of a video tag to perform video streaming pulling, and the multimedia video stream is played on a display screen. For example, the video stream address is rendered in the front-end page in the video tag format based on the decrypted target video stream address, and the < video > tag is used to embed the video element in the HTML page.
S130, when the fault information corresponding to the power swapping station is received, determining a fault position corresponding to the fault information, determining that the fault position corresponds to target display information in the multimedia video stream, and displaying the target display information in the played multimedia video stream in a distinguishing manner.
The fault information may correspond to a power swapping device in the power swapping station.
In this embodiment, when fault information of a certain power swapping device is received, the position information of the power swapping device may be determined as a fault position. Further, it may be determined that the fault location corresponds to target display information in the multimedia video stream, for example, the location of the battery swapping device is located at the left rear side in the battery swapping station, which location point on the display screen the location corresponds to may be determined based on the display scale of the entire battery swapping station on the display screen, and the information of the location point may be used as the target display information; the corresponding imaging device may be determined based on the failure position, and further, which area of the display screen the surveillance video corresponding to the imaging device is displayed in may be determined, which position point of which area of the display screen the surveillance video is displayed at may be determined based on the display area and the position information of the failure position in the video frame of the surveillance video, and the information of the position point may be used as the target display information. Furthermore, the target display information can be displayed in the played multimedia video stream in a distinguishing way, such as color change, information brightness enhancement and the like. Exemplarily, in a certain live streaming picture in a multimedia video stream, the currently monitored alarm information may be acquired in real time, such as: the power switching equipment has a fault in the power switching process, the station end of the power switching station can report the fault information of the power switching equipment to a maintenance record table of the server, and the server can return corresponding fault response to the front end and display the fault response in a monitoring page of the multimedia video stream, so that the effect of video monitoring synchronous alarm information is achieved, the monitoring force is improved, and the safety of the power switching station is guaranteed.
It should be noted that, the implementation manner of determining that the fault location corresponds to the target display information in the multimedia video stream and performing differential display on the target display information in the played multimedia video stream may be: determining corresponding target multimedia data based on the fault location; and determining target display information of the fault position in the video frame and displaying the target display information in a distinguishing way based on the target multimedia data and the multimedia video stream.
In this embodiment, target multimedia data corresponding to the failed power swapping device may be determined based on the failure location, for example, the target multimedia data includes text, graphics, images, animations, and the like associated with the power swapping device. Target display information of a fault location in a video frame of a multimedia video stream may be determined and displayed differently based on the target multimedia data.
