Detailed Description
The invention is described by taking android devices as examples, but is not limited to android devices, and is also applicable to OS system devices or other operating system devices.
According to the invention, the effect of synchronizing data of the target equipment from the cloud platform is realized through the IOT service. The devices are connected through the IOT, after the synchronous task is issued, the task is divided in the scheduling service and distributed to other devices (devices with the same device configuration information) with the same model or other devices and the target device for parallel processing, and after the parallel processing of the synchronous devices is successful, the IOT platform reversely sends the parallel processing result to the target device.
Example 1
A method for synchronizing data of Internet of things equipment and cloud platform comprises the following steps:
s1, recording equipment configuration information of terminal equipment connected with an IOT platform by a scheduling service of the IOT platform:
the process of establishing communication between the IOT server and the device terminal is shown in fig. 1:
firstly, adding equipment information on a cloud platform by a user;
secondly, adding equipment on the IOT platform through the IOT service module by the cloud platform, and storing equipment information by the equipment management module;
thirdly, starting the equipment, establishing long connection between the equipment end and the IOT platform through the SN number and carrying out authentication through the SN;
and fourthly, if the authentication is successful, each device subscribes the SN theme through the SN number to realize the concurrent isolation of the device end. The SN numbers are distinguished through SN numbers, namely/d/s/SN data channels, data transmission is carried out through the channels, and data isolation can be achieved without mutual interference. Such as devices sending messages to sn1, with topic/d/s/sn 1; messages sent to the devices of sn2 are with topic/d/s/sn 2.
The device side initializes the registration process, as shown in fig. 2:
firstly, after passing the authentication, the equipment establishes long connection with an IOT platform;
and secondly, sending registration information, namely the IP and the port of the equipment and equipment configuration information (CPU architecture and algorithm machine loading version) to the IOT platform.
And thirdly, the IOT platform synchronizes the IP and the port of the equipment and the equipment information to the dispatching service module.
The target device initiates a synchronization request (here, a synchronization face task is taken as an example); the scheduling service searches the equipment with the same equipment configuration information as the synchronous equipment, and issues the synchronous face task of the cloud platform to the synchronous equipment through the IOT platform:
after the target device initiates the synchronization request, the scheduling service synchronizes the device registration information to other devices, and the registration process is shown in fig. 3:
in the first step, the device sn1 sends registration information to the IOT platform;
the second step, the IOT platform synchronously registers information to the dispatching service;
thirdly, recording the association relation information: device information and device sn1, device sn1 and device IP and port;
and fourthly, searching the online equipment with the same configuration information according to the equipment. Assuming the same configuration equipment, sn2, sn 3;
fifthly, informing the IOT platform to send the IP of the equipment and the ports to sn2, sn3 in a group manner;
sixthly, the IOT platform informs sn2 and sn3 that the contents are as follows: sn1 corresponding IP and port.
After the synchronization device finishes registering, the synchronization task segmentation is started, and the synchronization task is segmented into a flow of block tasks, as shown in fig. 4:
firstly, the cloud platform initiates a synchronous task request to the IOT platform according to the sn1, wherein the request comprises a face library identification token 1.
And secondly, the IOT platform transparently transmits the message to the equipment.
And thirdly, the target equipment initiates application of synchronous face library content to the IOT platform according to the token 1.
Fourthly, the IOT platform is transmitted to the cloud platform
Fifthly, after receiving the message, the cloud platform issues the face library content according to token 1.
Sixthly, the IOT platform forwards the face content corresponding to the token1 to the scheduling service.
And seventhly, estimating the task size by the scheduling service.
If the task size is smaller than the threshold value, the first branch is taken:
the threshold is related to the block processing amount, and is assumed to be 100, and is smaller than the threshold as long as the number of faces in the synchronization task is smaller than 100. Taking 80 faces in synchronization as an example, the task size is smaller than the threshold.
Branching one: and step eight, informing the IOT platform to issue the synchronous task according to the sn 1.
Branching one: and step nine, the IOT platform directly issues the face content corresponding to the token1 to the corresponding equipment.
And if the task size is larger than the threshold value, a branch II is taken:
taking the threshold value of 100 and 680 human faces as an example, the task size is larger than the threshold value.
And branch two: and step eight, segmenting the task into a plurality of blocks.
And one synchronous task synchronizes 680 human faces, and each block can process 100 human faces, so that the number of the segmented blocks is 7. A block number is assigned to each block, such as: block number B1 for block 1, B2 for block 2, and B7 for … and block 7.
And branch two: and step nine, searching the online equipment with the same configuration information (the CPU architecture and the algorithm version are the same) and acquiring all the equipment sn meeting the conditions.
And branch two: step ten, numbering each device sn, such as: assuming that two devices meet the conditions, the device one specifies the number: 0, device two specifies the number: 1.
and branch two: and step ten, taking a hash value for the block number, and then taking a module to obtain a digital number corresponding to the step ten. The formula is as follows: block number hash value% number of devices = number.
Taking the number of blocks as 7 and the number of devices as 2 as an example, the calculation result obtained according to the modulus formula will fall within the range of 0-1, and exactly correspond to the number of the number corresponding to the tenth step.
Taking the number of blocks as 6 and the number of equipment as 6 as an example, the calculation result obtained according to the modulus formula will fall within the range of 0-5, and so on, and the corresponding equipment is assigned with the label number of 0-5.
And branch two: and step ten, according to the step ten and the step eleven, reversely checking and finding the equipment sn according to the number.
And branch two: and step three, issuing the blocking tasks in batches according to the hit equipment sn.
The block tasks of the blocks are executed in parallel, and the flow is shown in fig. 5:
assume that the block tasks are two:
in the first step, tasks 1 are issued to sn2, and the execution result is returned to the task scheduling module.
And in the second step, the tasks 2 are issued to the sn3, and the execution result is returned to the task scheduling module.
And thirdly, the scheduling task module collects the execution results (collects the face characteristic values extracted by each synchronous device).
After the synchronization device completes the synchronization task, the IOT platform sends the synchronization execution result to the target device, as shown in fig. 5:
and fourthly, sending an execution result to the IOT platform according to the target equipment.
And fifthly, the IOT platform issues an execution result (the summarized face characteristic value) to the target equipment.
