Fig. 1 illustrates an exemplary system architecture 100 to which embodiments of the edge device data access methods, apparatus, electronic devices, and computer-readable storage media of the present disclosure may be applied.
As shown in fig. 1, the system architecture 100 may include a cloud configuration platform 101, edge nodes 102, 103, and 104, and edge cameras 1031 and 1032 are further mounted below the edge node 103. The above-mentioned bodies act as a data transmission medium through a network. The network may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
A user may perform information interaction with the cloud configuration platform 101 through a network, for example, upload configuration parameters, view returned edge node status information, access data acquired by an edge device, and the like. Various applications for realizing information communication between the edge nodes 102, 103, and 104 and the cloud configuration platform 101 may be installed on the edge nodes and the cloud configuration platform 101, for example, a parameter configuration application, an information transmission application, an instant messaging application, and the like.
The edge nodes 102, 103, 104 and the cloud configuration platform 101 are typically represented by hardware devices of different forms, such as a laptop, a desktop, a workstation, a mainframe, a data center, and the like. In some special scenarios, the above-mentioned apparatus may also be represented as a virtual device, for example, in a test scenario of virtual simulation.
The cloud configuration platform 101 may provide various services through various built-in applications, and for example, a parameter configuration class application that may provide an edge device data access service is taken as an example, the cloud configuration platform 101 may receive a target configuration parameter issued by a user and issue the target configuration parameter to a corresponding target edge node 103, so that the target edge node 103 processes original video data acquired from the edge cameras 1031 and 1032 according to the target configuration parameter, and uploads the processed video data meeting the user requirements to a target address, so that the user can access the video data at any time.
The method for accessing edge device data provided in the subsequent embodiments of the present disclosure is generally executed by the cloud configuration platform 101 serving as a control center in the edge network, and accordingly, the edge device data access apparatus is also generally disposed in the cloud configuration platform 101.
It should be understood that the number of cloud configuration platforms, edge nodes, and edge devices, including edge cameras, in fig. 1 are merely illustrative. Any number of cloud configuration platforms, edge nodes, and edge devices may be provided as needed.
Referring to fig. 2, fig. 2 is a flowchart of an edge device data access method applied to a cloud configuration platform according to an embodiment of the present disclosure, where the process 200 includes the following steps:
step 201: receiving a target configuration parameter generated for a target edge node on which an edge device is mounted;
in this step, an execution subject of the edge device data access method (for example, the cloud configuration platform 101 shown in fig. 1) receives target configuration parameters written by a user for an edge device (for example, the edge cameras 1031 and 1032 shown in fig. 1) mounted on a target edge node (for example, the edge node 103 shown in fig. 1) on a platform configuration page provided by the cloud configuration platform, that is, the target configuration parameters are specified parameters of the edge device which are used for embodying a user's requirement, such as a data upload address, whether to start a frame extraction, a frame extraction frequency, whether to start a timed screenshot, a screenshot cycle, a data upload quality, a custom device name, whether to start a dynamic upload, and the like.
That is, the target configuration parameters are specified by the user without knowing the original configuration parameters of the edge device (for security, the edge device usually does not expose the real IP address and port number, and the edge device also usually does not have the real public network IP address), so that the target edge node of the target configuration parameters that is expected to be received can process the original data acquired according to the original configuration parameters according to various parameters in the configuration parameters, so that the user can finally check the desired data at the address set by the user.
Wherein, edge device still includes except can be more common edge camera: an edge microphone, an edge fill light, an edge signal light, an edge sensor, and the like.
Step 202: sending the target configuration parameters to the target edge nodes;
on the basis of step 201, in this step, the execution subject issues the written target configuration parameters to the target edge node desired or indicated by the user. The indication of the target edge node may be by distinguishing node names, node numbers, node features, and the like of different edge nodes, which is not specifically limited herein, for example, the edge node corresponding to the target cell may be designated as the target edge node.
Step 203: controlling the target edge node to process the original data acquired by the edge device according to the processing configuration in the target configuration parameters to obtain processed data;
based on step 202, in this step, the execution subject (e.g., the cloud configuration platform 101 shown in fig. 1) controls a target edge node (e.g., the edge node 103 shown in fig. 1) to process raw data collected by an edge device (e.g., the edge cameras 1031 and 1032 shown in fig. 1) mounted on the execution subject according to a processing configuration in the received target configuration parameters, so as to obtain processed data on the target edge node.
The target edge node finds the mounted edge device and obtains the original configuration parameters of the edge device in the same local area network, that is, one intranet device can find other network devices belonging to the same intranet through an intranet discovery technology (for example, relevant information or signals of other devices existing in the intranet can be found through a signal search technology, a signal scan technology or an information search technology), and of course, other network devices can also include other types except the edge device, so that the edge device can be screened out through the read device information after all other devices are found. The original configuration parameters of the edge device are configuration parameters usually provided by the driver installed by the manufacturer of the edge device when the edge device leaves the factory, such as default device name, default transport protocol, default access address, default push flow address, etc., and these parameters written in the driver often limit the functions that the edge device can provide and are difficult to realize by changing the driver by itself.
Meanwhile, because these parameters generally need to be determined and obtained based on the IP address and the port number, the edge device often cannot allocate a public IP and a port number, and the intranet IP also has no external accessibility, that is, no matter in consideration of security or other factors, how to safely obtain the data of the edge device that meets the user's needs is a matter of key consideration for those skilled in the art.
One implementation, including and not limited to, may be:
controlling the target edge node to search edge equipment which is positioned in the local area network;
and the control target edge node acquires the original data acquired by the edge equipment according to the original configuration parameters of the edge equipment. For example, a default RTSP (Real Time Streaming Protocol) stream address is determined by an intranet IP in the original configuration parameters, and the original data collected by the default RTSP stream address is pulled from the default RTSP stream address.
Step 204: and controlling the target edge node to carry out plug flow on the processed data to a plug flow address in the target configuration parameters through a secure transmission protocol.
On the basis of step 203, this step is intended to control, by the execution subject, the target edge node to forward the processed data to a forwarding address in the target configuration parameters through a secure transport protocol.
The secure Transport protocol refers to a Transport protocol for securing a Transport process, such as TLS (Transport Layer Security) which can provide Security and data integrity between two communication applications, or other protocols which can achieve similar effects. It should be noted that, compared with other secure transmission protocols, the TLS performs security verification on both sides in the handshake phase, and transmits the original data after passing the verification, because it is not necessary to encrypt the transmitted data on the data plane, the overall processing time is shorter, the efficiency is higher, and the method is more suitable for the scenario with higher real-time requirement.
That is, according to step 203 and step 204, the present embodiment initially divides the target configuration parameters into two parts: the method comprises a processing configuration for indicating how to process original video data according with the user's expectation and a plug flow address for indicating the address to which the processed data is uploaded, wherein the two parts jointly form a configuration parameter for meeting the most basic requirements of the user.
Further, in response to receiving a user-defined flow pushing address transmitted by a user, the default flow pushing address in the target configuration parameters is modified into the user-defined flow pushing address. That is, if the user-defined push flow configuration transmitted by the user is not received, the default push flow address in the target configuration parameter is maintained.
When the user does not have the streaming server, the cloud configuration platform shares the secure transmission protocol certificate issued by the cloud to the target edge node by default, so that the target edge node can be connected to the streaming server provided by the platform by default through the certificate; when the user owns other own streaming servers, the corresponding certificate of the target edge node can be bound through the cloud configuration platform, so that the configuration platform transmits the certificate of the user to the target edge node, and the target edge node transmits data to the own streaming servers through the self-defined certificate and the secure transmission protocol.
According to the data access method for the edge device, the mounted edge device is found by controlling the edge node in a manner of finding other devices belonging to the same local area network, the mounted edge device is used as an upper management device of the found edge device, and the original data acquired by the edge device is processed according to the target configuration parameters issued by the cloud configuration platform.
In order to better reflect how the edge node processes the original data according to the processing configuration in the target configuration parameters, the present embodiment further describes three different processing manners by the following three examples respectively:
first, when the processing configuration includes a frame extraction processing configuration and the edge device includes an edge camera, the execution main body can control the target edge node to perform frame extraction processing on the original video data acquired by the edge camera device according to the frame extraction processing configuration in the target configuration parameters, so as to obtain processed video data. For example, the original video with 30 frames per second is subjected to frame-alternate frame extraction processing, that is, the processed video data only has 15 frames per second, so as to reduce the data transmission amount in unit time by frame extraction. Of course, the frame extraction frequency can be set by itself according to actual requirements.
And secondly, under the condition that the processing configuration comprises a first conversion processing configuration and the edge device comprises an edge camera, the execution main body can control the edge node of the target to convert the data format and/or the transmission protocol of the original video data acquired by the edge camera according to the first conversion processing configuration in the target configuration parameters, so as to obtain the converted video data. That is, the first conversion processing configuration indicates to replace the data format and/or the adopted transmission protocol of the original video data, specifically, if the data format and the transmission protocol of the original video data are consistent with the first conversion processing configuration, no conversion is actually needed (only the user may not preset the original data format and the transmission protocol in advance, but only the target format and the target transmission protocol can be specified); if not, a conversion is required.
And thirdly, under the condition that the processing configuration comprises screenshot processing configuration and the edge device comprises an edge camera, the execution main body can control the edge node of the target to intercept the original video data acquired at the preset moment of the edge camera according to the screenshot processing configuration in the target configuration parameters to obtain screenshot data. For example, the screenshot is performed every 1 minute, so that the user can see the picture content of the object shot by the edge camera at intervals of 1 minute, and the method is suitable for regularly checking the moving and static scenes of the shot object.
Besides the processing modes of frame extraction, format/transmission protocol conversion and screenshot, the method can also comprise the following steps: the data quality adjustment (for example, reducing the video quality to reduce the occupation of bandwidth), the data uploading according to the period/interval period/designated period, etc. are not described herein.
In contrast to the conversion processing performed by the target edge node on the original video data based on the first conversion processing configuration, the present embodiment fully considers that some conversion requirements have a higher performance load pressure on the execution subject, and some edge nodes have a weaker performance, so that a flowchart of a method for accessing edge camera video data applied to the cloud configuration platform is further provided through fig. 3, where the process 300 includes the following steps:
step 301: receiving target configuration parameters generated for a target edge node on which edge equipment is mounted;
step 302: sending the target configuration parameters to the target edge nodes;
the above steps 301-302 are the same as the steps 201-202 shown in fig. 2, and for the contents of the same parts, reference is made to the corresponding parts of the previous embodiment, which is not repeated herein.
Step 303: controlling the target edge node not to process the original video data acquired by the edge camera according to a second conversion processing configuration in the target configuration parameters, and uploading the original video data and the second conversion configuration to a cloud cache through a secure transmission protocol;
different from the first conversion processing configuration in the above embodiment, in this embodiment, it is determined that the target configuration parameter includes a second conversion processing configuration, where the second conversion processing configuration is used to instruct the conversion processing operation on the original video data to be performed by a cloud with stronger performance, that is, the target edge node does not need to perform the conversion operation, so as to reduce the performance pressure on itself.
Of course, in addition to the explicit processing configuration indication, it is also possible to determine whether the conversion operation is suitable for itself according to the expected performance consumption of the conversion operation indicated by the conversion processing configuration, and to forward the conversion operation to the cloud end if it is determined that the conversion operation is not suitable for itself.
Step 304: and converting the data format and/or the transmission protocol of the original video data stored in the cloud cache according to the second conversion configuration, and pushing the obtained converted video data to a stream pushing address in the target configuration parameter through a secure transmission protocol.
On the basis of step 303, in this step, the execution main body performs conversion processing on the data format and/or the transmission protocol of the original video data stored in the cloud cache according to the second conversion configuration, and pushes the obtained converted video data to the push address in the target configuration parameter through the secure transmission protocol.
On the basis of any of the above embodiments, in consideration that a new edge device may be added to a target edge node at any time, and the added new edge device may have performance and function differences from an old edge device, it is necessary for the cloud configuration platform to know the new adding behavior, and to prepare for adjusting the overall target configuration parameters based on the new adding behavior. That is, in response to the target edge node searching for a new edge device (e.g., a newly added edge device or a replaced original edge device) in the lan, the target edge device sends a device change notification for the new edge device to the execution main body, so that the execution main body that receives the device change notification determines whether to adjust the target configuration parameters according to actual requirements of the user, determines the adjusted new target configuration parameters, and issues the new target configuration parameters again to validate the new target configuration parameters. Wherein, the issuing of the new target configuration parameter can be performed by OTA (Over-the-Air Technology ).
Specifically, the adjusting of the configuration parameter may include: the frame extraction frequency of the old edge equipment is adjusted, video data obtained by shooting of a certain old edge camera is not needed, the image quality of data shot by a certain old edge camera is adjusted, and the like, so that the requirements on performance and the occupation on bandwidth are reduced as far as possible under the condition of better meeting the requirements of users.
On the basis of any of the above embodiments, the performance load parameters returned by the target edge node may also be received, and the target configuration parameters are adjusted according to the performance load parameters, so as to fully consider the actual load and the operating state of the target edge node, thereby ensuring long-term, continuous, and stable operation of the target edge node. Wherein the performance load parameters include: CPU occupancy rate, memory occupancy rate, hard disk occupancy rate, error reporting rate in unit time, restarting rate and the like.
In the above embodiments, how to implement the entire technical solution is described from the perspective of a cloud configuration platform (e.g., the cloud configuration platform 101 shown in fig. 1), in order to facilitate understanding of operations performed by another execution subject, an edge node (e.g., the edge nodes 102, 103, and 104 shown in fig. 1) in the entire technical solution, the following embodiments will further describe the entire solution and operations performed by a target edge node as an execution subject from the perspective of the edge node:

For the operation of each embodiment in which the edge node is used as the execution subject, the expanded description may refer to the other embodiments, and the above embodiments have already described the manner and purpose of each operation in detail at corresponding parts, and are not described again here.
For further understanding, the present disclosure also provides a specific implementation scheme in conjunction with a specific application scenario, please refer to a flow 400 shown in fig. 4:
as shown in fig. 4, the scheme architecture provided by this embodiment includes two portions, a cloud and an edge, where the cloud includes the following portions:
BIE DashBoard module: the front-end control page of the BIE edge computing platform is used for configuring Rtsp Agent application by a user and providing viewing of HLS real-time video stream;
BIE Server module: providing an OpenAPI (Open Application programming Interface) for a BIE Dashboard to call, receiving operations and configurations of a user on a page, establishing TLS (HTTP Live Streaming), which is a dynamic code rate adaptive technology, with an edge node, synchronizing a request of the user to the edge node, and ensuring final consistency of data;
RTSP Server module: the default cloud end provided by the system receives the address of the RTSP streaming, and the function of the system is to receive the RTSP video stream bidirectionally authenticated by TLS, convert the received video stream into the video stream of HLS, and provide the BIE Dashboard for access.
Wherein the edge is composed of:
BIE Core module: actively establishing connection with the cloud. And starting the corresponding application and loading the configuration of the cloud according to the application issued by the cloud and the configuration in the edge equipment. It can also issue a certificate that the application can perform TLS communication authentication with the cloud. Meanwhile, an OpenAPI interface is provided for the edge application to check the dynamic data change of the cloud configuration.
RTSP Agent module: the edge application, pulled up by the BIE Core, can access the RTSP address provided by the camera in the same local area network as the edge device, depending on the configuration, and push to the address specified by the user in the configuration. If the user pushes the system default RTSP address, the certificate issued by the Core is loaded, and after authentication, stream pushing is performed. Meanwhile, the method can also perform frame extraction on the video stream, and provide OpenAPI for other applications of the user at the edge end to access.
Two flows are mainly introduced here, the first is a flow in which a user configures an RTSP Agent application and issues the application through a BIE edge computing platform:
(1) A user selects an RTSP (real time streaming protocol) Agent application in a BIE (building information infrastructure) Dashboard aiming at corresponding edge equipment, and performs configuration as shown in the specification on the application, wherein in the configuration, the user is connected with two cameras and both the two cameras are pushed to a default cloud address provided by a system, a camera1 defaults to start a streaming proxy, and a camera0 dynamically starts the streaming proxy in the subsequent introduction;
(2) After the configuration of the BIE Dashboard is completed, a user calls the OpenAPI of the BIE Server, the proxy application is established at the cloud end, and meanwhile, the application is issued to the BIE Core application where the equipment is located through a synchronization mechanism of the end cloud;
(3) The BIE Core application saves the configuration into a file by the edge device, takes the file as a starting parameter, pulls up the RTSP Agent application, and simultaneously issues a certificate for enabling the RTSP Agent to communicate with the RTSP Server;
(4) And the RTSPAgent is started, acquires the started Camera1 stream according to the configuration and pushes the started Camera1 stream to the RTSP Server. Meanwhile, the OpenAPI provided by the BIE Core is called regularly (every 30 s), whether the proxy state is started by the latest camera set by the current cloud is determined, and the current proxy camera state is reported.
The following description is how a user dynamically controls the RTSP proxy to be opened through the node shadow, and remotely views the real-time video stream through the BIE Dashboard:
(1) The user opens the camera0 switch in the edge node at the BIE Dashboard. The front end calls the OpenAPI of the BIE Server. The message is synchronized to the edge BIE Core by the BIE Server through a terminal cloud synchronization mechanism;
(2) When the RTSP Agent acquires the latest control state of the cloud at the next time, finding that a proxy cmaera0 is newly added in the Core, at the moment, acquiring RTSP stream of the Camera0 similarly to the Camera1, and pushing the RTSP stream to the cloud;
(3) Meanwhile, since camera0 starts frame extraction 30 times per second, the RTSP Agent also provides OpenAPI, and the edge application of the user can access the frame extraction result in the latest one second at the following addresses;
(4) At this time, after receiving the video stream, the Rtsp Server in the cloud converts the video stream into an HLS real-time video stream address, which is directly accessible to the BIE Dashboard.
