Background technique

In the early stage of the development of smart security, the platform performance of front-end monitoring equipment was limited, and it was not enough to support processing a large number of intelligent analysis calculations. The front-end monitoring equipment collected data and transmitted the data to the back-end server or cloud computing platform for intelligent analysis.

With the development of ultra-high-definition and 4K high-definition display technology and the access of a large number of devices, intelligent security systems are facing problems such as insufficient bandwidth, increased latency, and increased number of servers. At the same time, with the enhancement of the computing power of the video surveillance front-end and the emergence of dedicated chips, intelligent front-end is possible. Intelligent front-end equipment can preprocess video images to remove image redundant information, so that part or all of the video analysis is migrated to front-end computing, reducing the computing, storage and network bandwidth requirements of the cloud center, and improving the response speed of the equipment.

In the context of smart computing front-end, the computing and storage capabilities of access devices (smart front-end devices) are different and change over time. In addition, the types of tasks undertaken by different access devices are not the same, such as the need for cross-border alarm analysis near the perimeter, face capture at entrances and exits, and license plate recognition on the road.

Most of the data storage and computing tasks in front-end computing rely on smart front-end equipment. Unlike cloud computing centers that have stable infrastructure protection, many smart front-end devices are exposed to the natural environment for a long time and are easily damaged by natural or man-made damage. In the context of front-end intelligent computing, the reliability of the entire security system and the stability of computing face new problems.

The distributed computing and storage system is highly scalable, and realizes a unified external service interface through the intelligent gateway service, which reduces the difficulty of equipment access.

The smart gateway is the hub that connects the smart front-end device and the back-end server (cloud server and/or local server), and provides various service functions through API (Application Programming Interface) interfaces. For example, the smart front-end device can call the interface to register, the back-end server can call the interface to view the device information of the currently connected smart front-end device, and the smart front-end device initiates a request for computing resources.

The intelligent front-end equipment receives instructions from the back-end server and processes tasks, and can provide computing, storage and forwarding functions through API interfaces.

The information includes the communication address of the smart front-end device and storage and computing capability information.

Example 2

This example provides a resource scheduling method. When the smart front-end equipment is overloaded and unable to receive new tasks, it can request computing resources from the smart gateway. The smart gateway searches for all smart front-end devices in the cluster and comprehensively considers the computing, storage, and communication capabilities of the equipment to select suitable ones. And then forward the computing service address of the appropriate smart front-end device to the smart front-end device requesting computing resources. Forwarding computing resources through the smart gateway can prevent a certain smart front-end device from being overloaded with tasks.

As shown in Figure 8, the resource scheduling method of this example may include the following steps:

Step S101: The background server delivers tasks to the smart front-end device A through the smart gateway.

Step S102: After receiving the task, the smart front-end device A judges whether the current load exceeds the threshold, and if it exceeds the threshold, it initiates a request for computing resources to the smart gateway;

Step S103: After receiving the request, the smart gateway searches for all smart front-end devices in the cluster and comprehensively considers the computing, storage, and communication capabilities of the devices to select a suitable smart front-end device B, and then forwards the computing service address of the smart front-end device B To smart front-end equipment A.

Step S104: After the smart front-end device A obtains the service address of the smart front-end device B, the task is transferred through the interface provided by the smart front-end device B, and the data required for the calculation task can be sent to the smart front-end device B when needed.

Step S105: The smart front-end device B performs calculation after obtaining the task, and then forwards the calculation result to the background server through the smart gateway.

Example 3

This example provides a resource scheduling method. When the smart gateway receives the task sent by the back-end server, it can determine whether the current device is capable of computing by obtaining the current resource status of the smart front-end device. If the computing power is insufficient, it searches for all smart front-end devices in the cluster and comprehensively considers the device's Computing, storage and communication capabilities, etc., screen out the appropriate smart front-end equipment, and then send the task to the appropriate smart front-end equipment, and at the same time forward the relevant service address of the original smart front-end equipment to the new smart front-end equipment, the new smart front-end equipment Relevant data can be obtained from the original smart front-end equipment. Forwarding computing resources through the smart gateway can prevent a certain smart front-end device from being overloaded with tasks.

As shown in Figure 9, the resource scheduling method of this example may include the following steps:

Step S102: The smart gateway first judges whether device A has enough computing resources to perform the task. If the computing power is insufficient, it searches for a suitable smart front-end device B with computing power that meets the requirements; among them, the bandwidth of the device is considered when searching, and the calculation and Storage capacity.

Step S103: The smart gateway forwards the calculation task to the smart front-end device B, and sends the related service address of the smart front-end device A to the smart front-end device B.

Step S104: The smart front-end device B performs calculations after receiving the task and the related service address of the smart front-end device A.

Among them, the smart front-end device B obtains relevant data according to the relevant service address of the smart front-end device A;

For example, the task sent by the back-end server is to perform image analysis on the video surveillance data of the smart front-end device A. Since each smart front-end device can only obtain the video data in its own monitoring area, the smart front-end device B needs to obtain the video data from the smart front-end device. A get the relevant data, and then calculate.

In addition, since the computing tasks are of multiple types, when the computing task does not need to rely on the data in the smart front-end device A, the smart gateway may not send the relevant service address of the smart front-end device A to the smart front-end device B; when the computing task requires When relying on the data in the smart front-end device A, the smart gateway sends the related service address of the smart front-end device A to the smart front-end device B, and the smart front-end device B obtains the related data according to the related service address of the smart front-end device A.

Step S105: After the calculation of the smart front-end device B is completed, the calculation result is forwarded to the back-end server through the smart gateway.

Example 4

This example provides a resource scheduling method. When the back-end server issues a backup or data migration instruction to the smart front-end device A, the smart gateway first determines whether the current smart front-end device A has enough storage space to store data. If the space is not enough, it searches for a suitable smart front-end through a certain strategy Devices B and C, and send the searched storage addresses and task instructions of smart front-end devices B and C to smart front-end device A together. When the smart front-end device A receives the instruction, the data to be stored is evenly sliced, and the data is transferred through the received storage addresses of the smart front-end devices B and C in turn. Forwarding storage resource backup requests through the intelligent gateway service can prevent a certain intelligent front-end device from causing data loss due to certain factors, and improve data reliability.

As shown in Figure 10, the resource scheduling method of this example may include the following steps:

Step S101: The background server issues a backup or data migration task to the smart front-end device A through the smart gateway.

Step S102: The smart gateway first determines whether the current smart front-end device A has enough storage space to store data, and if the space is not enough, it searches for suitable smart front-end devices (for example, smart front-end devices B and C) through a certain strategy.

Step S103: The smart gateway forwards the storage service address list (B, C) and storage instructions of the smart front-end device to the smart front-end device A.

Step S104: After the smart front-end device A obtains the storage instruction and the storage service address list, the data that needs to be backed up or migrated is evenly transferred to other smart front-end devices.

Step S105: The smart front-end device A sends the task execution result to the smart gateway.

Among them, for backup tasks, task execution results include: backup success or backup failure;

For data migration tasks, the task execution results include: data migration success or data migration failure;

Step S106: the smart gateway stores the data relationship;

When the smart front-end device A has insufficient storage space and cannot receive new backup or data migration tasks, it can request storage resources from the smart gateway. The smart gateway searches for suitable smart front-end devices B and C through a certain strategy, and then determines the appropriate The storage service address of the smart front-end device is forwarded to the smart front-end device A that requests storage resources. When the smart front-end device A receives the instruction, the data to be stored is evenly sliced, and the data is transferred through the received storage addresses of the smart front-end devices B and C in turn. Forwarding storage resource backup requests through the intelligent gateway service can prevent a certain intelligent front-end device from causing data loss due to certain factors, and improve data reliability.

As shown in Figure 11, the resource scheduling method of this example may include the following steps:

Step S102: After receiving the task, the smart front-end device A judges whether there is enough storage space to store data, and if the space is not enough, it initiates a request for storage resources to the smart gateway;

Step S103: After receiving the request, the smart gateway searches for suitable smart front-end devices (for example, smart front-end devices B and C) through a certain strategy.

Step S106: The smart front-end device A sends the task execution result to the smart gateway.

Step S107: the smart gateway stores the data relationship;

Step S108: The smart gateway sends the task execution result to the background server.

Example 6

This example provides a resource scheduling method. When the back-end server issues a data recovery instruction to the smart front-end device A, the smart gateway sends the previously stored service storage address and task instructions to the smart front-end device A together. When the smart front-end device A receives the task instruction, it first determines whether the storage address of the backup data is stored locally, and if not, it restores the data through the storage address passed by the gateway. Forwarding the data recovery request through the intelligent gateway service can prevent a certain intelligent front-end device from causing data loss due to certain factors, and improve the reliability of the data.

As shown in Figure 12, the resource scheduling method of this example may include the following steps:

Step S101: The background server issues a data recovery task to the smart front-end device A through the smart gateway.

Step S102: The smart gateway forwards the data recovery instruction and the server address list (smart front-end device B, C) for data backup or migration to the smart front-end device A.

Step S103: After receiving the instruction, the smart front-end device A first searches whether the server address for data backup or migration is stored locally, and if not, it uses the address list passed by the smart gateway.

Step S104: The smart front-end device A restores the data through the address list.

Among them, smart front-end device A obtains data from smart front-end devices B and C respectively according to the server address of the data backup or migration;

Step S105: The smart front-end device A forwards the task execution result to the back-end server through the gateway.

Among them, the task execution result refers to: data recovery success or data recovery failure.

Example 7

This example provides a resource scheduling method. When the smart gateway loses connection with the smart front-end device, the smart gateway selects the appropriate one through a certain search strategy (considering the distance between other smart front-end devices and the smart front-end device that has lost contact, communication capabilities, and current resource utilization) Smart front-end device B then initiates a transfer request to smart front-end device B, smart front-end device B establishes a connection with smart front-end device A, and all subsequent messages sent by smart front-end device A to the smart gateway are forwarded by smart front-end device B. When a smart front-end device loses connection with the smart gateway, data can be transferred through other smart front-end devices in the cluster, thereby improving the reliability and stability of the system.

As shown in Figure 13, the resource scheduling method of this example may include the following steps:

Step S101: The background server issues a task instruction to a certain smart front-end device (smart front-end device A).

Step S102: The smart gateway tries to forward the task instruction to the smart front-end device A for multiple times.

Step S103: After the smart gateway fails to attempt to communicate with the smart front-end device A, it searches for the best transit device (the smart front-end device B) through a certain search strategy.

Step S104: The smart gateway initiates a transfer request to the smart front-end device B, and provides the wireless communication address of the smart front-end device A.

Step S105: After receiving the transfer request, the smart front-end device B actively establishes a communication connection with the smart front-end device A, and forwards the instruction to the smart front-end device A.

Step S106: The smart front-end device A performs calculations after receiving the instruction, and then returns the calculation result to the smart front-end device B;

Step S107: The smart front-end device B feeds back the calculation result to the back-end server through the smart gateway.
