Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The terms "first," "second," "third," and the like in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", and "a third" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments without conflict.
The following describes the process of accessing the existing internet of things equipment into the video monitoring cloud platform in detail:
from the perspective of equipment types, the Internet of things equipment which is supported by the video monitoring platform to be accessed can be divided into audio and video acquisition equipment, bayonet camera equipment, RFID, MAC, a barrier gate, an alarm host and the like. From the perspective of equipment manufacturers/equipment models/equipment versions, the Internet of things equipment which is supported to be accessed by the video monitoring platform can be divided into Internet of things equipment of different equipment manufacturers/equipment models/equipment versions.
Referring to fig. 1 in combination, an access node cluster of a video surveillance cloud platform includes an access management node and a plurality of access nodes. When various kinds of to-be-accessed internet of things equipment (to-be-accessed equipment) have access requirements, the access management node distributes the to-be-accessed equipment to a proper access node so that the to-be-accessed equipment is connected to the video monitoring cloud platform through the access node.
However, long-term researches of the inventor of the application find that under the access flow, the stability of the access node cluster is poor, and the access capability of the access node cluster cannot be fully exerted. The specific reason is that:
the access protocols of different kinds of internet of things equipment are not standardized, namely, the access protocols of the internet of things equipment with different equipment types can be different, and the access protocols of the internet of things equipment with the same equipment type and different manufacturers/models/versions can be different. In order to support access of all kinds of internet of things devices, each access node in the access node cluster needs to integrate access protocols of different kinds of internet of things devices. Some of these access protocols are developed based on vendor-supplied documentation, and some are vendor-supplied SDK packages that are available for integration.
During the access procedure, each access node needs to start all the different access protocol software modules. If a problem occurs in the access protocol software module of an internet of things device of a certain device class or classes, for example, a program bug or a security bug exists, all access nodes of the access node cluster may not work normally because the access protocol or protocols are started. Therefore, the stability of the access node cluster is poor, and the access capability of the access node cluster cannot be fully exerted.
The method provided by the application is introduced as follows, wherein for simplifying the description, a video monitoring platform is simply called a platform, and an internet of things device is called a device:
fig. 2 is a flow chart of an embodiment of a method for accessing a platform by a device of the present application. It should be noted that, if there are substantially the same results, the embodiment is not limited to the flow sequence shown in fig. 2. As shown in fig. 2, the present embodiment may include:
s11: and acquiring equipment information of equipment to be accessed.
The device information includes a device class. The device class of the device to be accessed may be embodied by at least one of a device type, a device vendor, a device model, a device version. For example, embodied by the device type and device vendor, this step may include: and obtaining the equipment type and equipment manufacturer of the equipment to be accessed.
In other embodiments, the device information may also include login information, address, listening port, etc. of the device to be accessed.
S12: and determining an access node group of the equipment to be accessed in the platform according to the equipment type.
The platform comprises at least two access node groups, wherein the access node groups comprise at least one access node; the access node group is for at least one device class; the device class used by each access node group is at least partially different.
For example, the platform includes 2 access node groups, one for a primary device class, which has a large number of devices, and another for other device classes. For another example, the platform includes 2 access node groups, one for the a vendor and another for the other vendors, which have a high probability of experiencing problems with respect to the access protocol of the a vendor. For another example, the platform includes 4 access node groups, where the 4 access node groups are used for the audio and video device of the manufacturer, the audio and video device of the third party manufacturer, the bayonet camera device of the manufacturer, and other devices.
The number of access nodes of an access node group may be determined based on the number of devices of the device class for which the access node group is intended. For example, the access node group for the device class A, B, the number of access nodes of the access node group may be calculated as follows:
calculation result 1 = number of devices a + number of devices B + load of devices B;
or, the calculation result 1=the number of devices a×the equivalent load of devices a+the number of devices b×the equivalent load of devices B.
And rounding up the calculation result 1 to obtain the number of access nodes. For a relevant explanation of the load and equivalent load reference is made to the following examples.
S13: the device to be accessed is allocated to the node to be accessed in the determined access node group so as to be connected to the platform.
The node to be accessed may be determined based on the determined current load of each access node in the group of access nodes, e.g. access node group 1. The access management node maintains a current load table of the access nodes, and the current load of each access node can be determined from the current load table of the access nodes. The node to be accessed may be determined based on the access node current load table. An example of the access node current load table is shown in table 1 below:
TABLE 1
| Access node ID | Access node IP | Current load | Access node group |
| A | 192.168.1.10 | 0.4451 | Access node group 1_ID |
| B | 192.168.1.11 | 0.4502 | Access node group 1_ID |
| … | … | … | Access node group 2_id |
As shown in table 1, the mapping relationship among the access node, the current load and the access node group to which the current load belongs is recorded in the current load table of the access node. From this, it can be determined that the current load of access node group 1 is 0.4451 and the current load of access node B is 0.4502.
The node to be accessed can be any one access node with the residual load larger than the load of the equipment to be accessed in the determined access node group, and the residual load is the difference between the maximum load and the current load. For example, the one with the smallest current load.
Referring to fig. 3 in combination, in case of assigning a device to be accessed to an access node of the smallest current load, S13 may include the following sub-steps:
s131: and calculating the sum of the load of the equipment to be accessed and the minimum current load.
The load of each kind of device is the same, and the load of the access node is equal to the number of devices accessed by the access node multiplied by the load of the devices. Thus, the current load of the access node is equal to the number of devices currently accessed by the access node multiplied by the load of the devices, and the maximum load of the access node is equal to the maximum number of devices accessed by the access node multiplied by the load of the devices, and the maximum number of devices accessed by each access node is the same.
In an embodiment, the sum of the load of the device to be accessed and the minimum current load may be calculated directly.
The load of different kinds of devices can be different due to different CPU, memory, network resource consumption and the like of the different kinds of devices. For example, the network resource consumption required by the access of the audio-video device is larger than that required by the RFID device, and the load of the audio-video device is larger than that of the RFID device. Therefore, if the sum of the load of the device to be accessed and the minimum current load is directly calculated in S131, load balancing of the access node may not be achieved, instability is brought to the access node, and the access node in the access node group may not be fully utilized.
For this purpose, in another embodiment, the equivalent load of the device to be accessed with respect to the node to be accessed may be obtained, and the sum of the equivalent load and the minimum current load is calculated.
The equivalent load is the maximum load of the node to be accessed divided by the maximum load number of the equipment to be accessed in the access node. The maximum load number of the to-be-accessed devices in the to-be-accessed node refers to the maximum number of the to-be-accessed devices which can be accessed when the to-be-accessed node is only used for accessing the to-be-accessed devices.
Alternatively, the equivalent load is the maximum load of the access node cluster divided by the maximum load number of devices to be accessed in the access node cluster. The maximum load number of the equipment to be accessed in the access node cluster refers to the maximum number of the equipment to be accessed which can be accessed when the access node cluster is only used for accessing the equipment to be accessed.
The equivalent load may be obtained from a device equivalent load table maintained by the access management node based on the device class. Examples of device equivalent load tables are shown in Table 2 below:
TABLE 2
| Equipment manufacturer | Device type | Equivalent load | Access node group |
| A | Audio-video equipment | 0.002 | Access node group 1_ID |
| A | Bayonet camera | 0.001 | Access node group 2_id |
| A | RFID | 0.0001 | Access node group 3_id |
| … | … | … | … |
As shown in table 2, the device equivalent load table records the corresponding relationship between the device type (device manufacturer, device type), the equivalent load and the access node group to which the device belongs. From this, it can be determined that the equivalent load of the audio and video device from vendor a is 0.002, the equivalent load of the bayonet camera from vendor B is 0.001, and the equivalent load of the RFID from vendor a is 0.0001, ….
As an example, a comparison of the sum based on the load calculation and the sum based on the equivalent load calculation is described as follows:
the access node group comprises access nodes 1-3, the maximum load of each access node is 1, and the load of each type of equipment is 0.11. The access node 1 has currently accessed 7 devices with a current load of 0.7. The access node 2 has currently accessed 6 devices with a current load of 0.6. The access node 3 has currently accessed 5 devices with a current load of 0.5. The node to be accessed is the access node 3, and the minimum current load is 0.5.
Thus, under the condition of calculating the sum of the loads of the equipment to be accessed, the sum of the loads of the equipment to be accessed and the minimum current load is calculated to be 0.5+0.1=0.6. Under the condition of calculating the sum of the equivalent loads of the equipment to be accessed, the maximum number of the equipment to be accessed which can be accessed by the access node is 5, and the equivalent load of the equipment to be accessed relative to the access node obtained from the equivalent load table is equal to 1/5=0.2; the sum of the calculated equivalent load and the minimum current load is 0.5+0.2=0.7.
S132: and judging whether the maximum load of the access node is smaller than the minimum current load.
If yes, executing S133; if not, S134 is performed.
S133: and distributing the equipment to be accessed to the access node with the minimum current load.
S134: not allocated.
In addition, after the equipment to be accessed is successfully connected to the platform, the current load of the node to be accessed can be updated, so that the subsequent access of new equipment to be accessed is facilitated. If the sum is calculated based on the load of the device to be accessed in S131, the current load of the node to be accessed is updated to be the sum of the current load of the node to be accessed and the load of the device to be accessed. If S131 is based on the sum of the equivalent loads of the devices to be accessed, the current load of the nodes to be accessed is updated to be the sum of the current load of the nodes to be accessed and the equivalent load of the devices to be accessed.
S11 to S13 will be described below in an example with reference to fig. 4:
as shown in FIG. 4, the platform comprises access node groups 1-4, and the access node groups 1-4 are respectively applied to audio and video equipment, third party audio and video equipment, bayonet cameras and other equipment of the manufacturer.
And when the equipment to be accessed has an access requirement, acquiring the equipment type of the equipment to be accessed, and determining an access node group of the equipment to be accessed according to the equipment type. For example, the device type of the device to be accessed is a bayonet camera device, then a node to be accessed is determined from the access node group 3, and the device to be accessed is allocated to the node to be accessed.
Through implementation of this embodiment, the application divides the access node cluster of the platform into at least two access node groups, each access node group comprising at least one access node, each access node group being for at least one device class, the device classes for each access node group being at least partially different. Therefore, the same access node group only needs to integrate the access protocol of the corresponding equipment type and start the access protocol software module of the corresponding equipment type, even if the access protocol software module of one or more equipment types has problems, the influence range is limited to be applied to the access node group of the equipment type or the equipment types, and the access of the access node groups of other equipment types can not be influenced. Therefore, the stability of the access node cluster can be improved on the whole, and the equipment access capability of the platform/access node cluster is fully utilized. And the mode of dividing the access node cluster into at least two access node groups is flexible, and the applicability is wide.
Further, according to the access mode, the devices can be divided into an active access device and a passive access device, and the access modes of the active access device and the passive access device are different.
The passive access device opens a monitoring port, passive monitoring is performed, and the access node accesses the address of the passive access device and the port to initiate active connection, thereby completing access. The method can be concretely as follows:
fig. 5 is a flow chart of another embodiment of a method for accessing a platform by a device of the present application. It should be noted that, if there are substantially the same results, the embodiment is not limited to the flow sequence shown in fig. 5. In this embodiment, the device to be accessed is a passive access device. As shown in fig. 5, the present embodiment may include:
s21: device information is received from a user interface.
The related personnel can input the equipment information of the equipment to be used through a user interface (SaaS service platform interface). The device information may include a device type, login information, an address, and a port.
S22: and determining an access node group of the equipment to be accessed in the platform according to the equipment type.
S23: and transmitting the equipment information of the equipment to be accessed to the nodes to be accessed of the determined access node group so that the nodes to be accessed establish connection with the equipment to be accessed based on the equipment information.
After the node to be accessed receives the device information, the validity of the device to be accessed can be verified based on the device information. For example, the node to be accessed logs in the device to be accessed by using the login information to verify whether the login information, the address and the like are correct. If the verification is successful, the connection is established with the equipment to be accessed.
S21 to S23 will be described as a specific example with reference to fig. 6 as follows:
after a constructor installs a device to be accessed on site, informing a manager of device information (device type, device manufacturer, IP address, account number and password of the Internet of things device) of the device to be accessed, and further inputting the device information through a user interface by the manager, so that the following access flow can be triggered:
1) The access management node receives equipment information of equipment to be accessed, which is input by a manager in a user interface, and obtains an equivalent load (Ld) of the equipment to be accessed and an access node group based on equipment type and equipment manufacturer.
2) The access management node determines the access node of the smallest current load (denoted ln) from the group of access nodes as the node to be accessed.
3) What is the access management node determines that ld+ln is less than or equal to 1 is satisfied? If so, enter 4).
4) And sending the equipment information of the equipment to be accessed to the node to be accessed.
5) And the node to be accessed performs validity verification on the device to be accessed based on the device information.
6) If the verification is passed, the node to be accessed and the equipment to be accessed are connected.
The access mode of the active access device is that the active access device sends a fixed address to a platform: a PORT (hereinafter referred to as the address of the peripheral node of the platform) initiates an active connection request to access the platform. The method comprises the following steps:
fig. 7 is a flow chart of a further embodiment of a method for accessing a platform by a device of the present application. It should be noted that, if there are substantially the same results, the present embodiment is not limited to the flow sequence shown in fig. 7. In this embodiment, the device to be accessed is an active access device. As shown in fig. 7, the present embodiment may include:
s31: and receiving the equipment information sent by the peripheral node.
The device information is sent by the device to be accessed to the peripheral node.
The peripheral node may be one access node in a cluster of access nodes. After receiving the device information of the device to be accessed, the peripheral node performs validity verification on the device information, and if the verification is successful, the peripheral node forwards the device information to the access management node.
S32: and determining an access node group of the equipment to be accessed in the platform according to the equipment type.
S33: and sending the determined address of the node to be accessed in the access node group to the peripheral node, so that after the peripheral node sends the address of the node to be accessed to the equipment to be accessed, the equipment to be accessed establishes connection with the node to be accessed based on the address of the node to be accessed.
The device to be accessed initiates a connection request to the node to be accessed based on the address of the node to be accessed, and the node to be accessed responds to the connection request to establish connection with the device to be accessed.
S33 may be regarded as a procedure for redirecting the device to be accessed to the node to be accessed, which is premised on the device to be accessed supporting the redirection. If the device to be accessed does not support redirection, the peripheral node is taken as the node to be accessed, and the peripheral node completes access.
S31 to S33 will be described as a specific example with reference to fig. 8 as follows:
the device to be accessed is a home device, which is located in the local area network. After the access equipment is installed, the following access flow can be triggered:
1) The device to be accessed sends device information to the peripheral node.
2) And the peripheral node performs validity verification on the device information. Forwarding to the access management node.
3) If the verification is successful, the access management node determines the node to be accessed based on the equipment information, and sends the address of the node to be accessed to the peripheral node.
4) The peripheral node sends the address of the node to be accessed to the device to be accessed.
5) The device to be accessed initiates a connection request to the node to be accessed based on the address of the node to be accessed.
6) And the node to be accessed performs validity verification on the equipment information.
7) If the verification is passed, a connection is established with the node to be accessed in response to the connection request.
In addition, in any of the above embodiments, there may be many factors that may cause the device to be accessed to be unsuccessfully allocated to the access node, for example, the determined remaining load of the access node in the access node group is smaller than the load of the device to be accessed, the validity verification is not passed, the network quality is poor, and so on. If the allocation to the access node cannot be successfully performed, a prompt can be given to the equipment to be accessed, so that the equipment to be accessed can know the reason of the failure to be allocated, and the equipment to be accessed can also send an access request again according to the prompt.
