Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by the person skilled in the art based on the present application are included in the scope of protection of the present application.

When the internet of things device needs to transmit files, the traditional internet of things device file transmission scheme is to directly transmit file data to the internet of things management platform, and the internet of things management platform is required to support mass file transmission. Although the object storage capacity provided by public cloud is adopted in the storage of the rear-end file, each Internet of things device still requests an Internet of things management platform, and the Internet of things management platform is responsible for managing the storage of the file transmitted by the Internet of things device in response to the request. But the scheme is difficult to fully exert the mass processing capacity of public clouds. Today, public cloud infrastructure is gradually perfected, the scheme brings the problem of repeated construction of resources of an Internet of things management platform, and mass processing capacity of public cloud is not beneficial to being directly utilized.

In the related art, the public cloud SDK can be integrated in the internet of things device, so that the internet of things device directly accesses the public cloud through the SDK to store files, and therefore the mass processing capacity of the public cloud is directly utilized, but the internet of things device and a corresponding designated public cloud manufacturer are bound to a certain extent, so that the internet of things device needs to update and upgrade the SDK bound with the internet of things device together when the version of the internet of things device is updated, the problem that the internet of things device and the SDK are difficult to update and upgrade is caused, and the problem that the integration of the internet of things device is complex is brought.

Based on the above, in order to reduce the integration complexity of the internet of things equipment, the embodiment of the application provides a method, a system and a device for transmitting the files of the internet of things equipment. The method for transmitting the file of the internet of things device provided by the embodiment of the application is firstly illustrated in the following.

The method for transmitting the files of the Internet of things equipment provided by the embodiment of the application is applied to an Internet of things management platform, and as shown in fig. 1, the method specifically comprises the following steps:

s101, receiving a file transmission request sent by the Internet of things equipment.

The file transmission request is sent when the file transmission function of the internet of things device is in an on state.

S102, responding to the file transmission request, and acquiring the address and the access protocol of the target storage node.

And S103, sending the address and the access protocol to the Internet of things equipment, so that the Internet of things equipment uses the access protocol to access the address, establishes communication connection with the target storage node, and transmits the file to the target storage node through the communication connection.

By applying the embodiment of the application, when the Internet of things management platform receives the file transmission request sent by the Internet of things device, the address and the access protocol of the target storage node can be obtained in response to the file transmission request, and the address and the access protocol of the target storage node are sent to the Internet of things device, so that the Internet of things device accesses the address of the target storage node by using the access protocol of the target storage node, establishes communication connection with the target storage node, and transmits the file to the target storage node through the communication connection. In the embodiment of the application, after the internet of things management platform receives the file transmission request of the internet of things equipment, the address and the access protocol of the target storage node are sent to the internet of things equipment, so that the internet of things equipment does not need to be configured with the protocol adapted to the storage node, but the access protocol of the target storage node sent by the internet of things management platform can be subjected to protocol adaptation with the storage node, and the file transmission is completed according to the address and the access protocol of the target storage node sent by the internet of things management platform, therefore, the internet of things equipment and the storage node are not bound, the decoupling of the internet of things equipment and the storage node is realized, and the integration complexity of the internet of things equipment is reduced.

The foregoing S101 to S103 will be described below, respectively, in which:

in S101, it may be understood that, when the file transfer function of the internet of things device is in an on state, the internet of things device may send a file transfer request to the internet of things management platform. However, the internet of things device does not immediately send a file transmission request to the internet of things management platform when the file transmission function is started, but sends the file transmission request to the internet of things management platform when the file transmission is needed. The method comprises the steps that when the file transmission function is in an on state and file transmission is needed, the Internet of things equipment sends a file transmission request to an Internet of things management platform.

In S102, the internet of things management platform responds to the received file transfer request, determines a storage node from the plurality of storage nodes as a target storage node, and obtains an address and an access protocol of the target storage node.

The method for determining the target storage node is not limited in any way, and the method for determining the target storage node is described in the following by way of example and not described in detail herein.

Each storage node is provided with a corresponding storage node number, and the information of all the storage nodes is stored in the internet of things management platform, wherein the information comprises the storage node numbers, the corresponding storage node addresses, access protocols and other detailed information. The information of the storage nodes is created in advance and stored in the Internet of things management platform when the storage nodes are newly added. The internet of things management platform can query information of the storage node according to the number of the storage node, can judge cloud manufacturers to which the storage node belongs according to the queried information, and acquire available protocols of the corresponding cloud manufacturers, namely acquire access protocols corresponding to the storage node.

In S103, the internet of things management platform may assemble the address and the access protocol of the target storage node according to the data exchange protocol between the internet of things device and the internet of things management platform, obtain a request response result, compress and encrypt the request response result, and then send the request response result to the internet of things device.

An exemplary description of how the target storage node is determined is as follows:

in one possible embodiment, any one of the plurality of storage nodes may be the target storage node.

In one possible embodiment, a geographic location where the internet of things device is located may be obtained; and determining a target storage node which meets the preset condition and is in a preset available state from the distance between the target storage node and the geographic position.

The preset condition may mean that a distance between an area where the storage node is located and a geographic location of the internet of things device is smaller than a preset distance threshold, the preset distance threshold may be set according to actual requirements, and specifically, the preset distance threshold may be 1 km, 2 km, 5 km, and the like. The preset condition may also refer to that the area where the storage node is located and the geographic location where the internet of things device is located are located in the same province or in the same city, and so on.

The state in which the storage node is may be determined by the network connectivity and/or load capacity of the storage node. The preset available state may refer to that the network connectivity of the storage node is higher than a preset network connectivity threshold, the network connectivity of the storage node may be represented by a return rate of data packets sent by the storage node, and the storage node sends 4 data packets and returns 4 data packets, where the data packets are not lost, the return rate is 100%, which indicates that the network connectivity of the storage node is good, the storage node sends 4 data packets and returns 0 data packets, and the data packets are all lost, the return rate is 0, which indicates that the network connectivity of the storage node is poor. The preset network connectivity threshold may be set according to actual requirements, and specifically, the preset network connectivity threshold may be 80%, 90%, 95%, and so on.

The preset available state may also refer to that the load capacity of the storage node is higher than a preset load capacity threshold, and the load capacity of the storage node may be represented by the number of requests acceptable by the storage node in a unit time, where the preset load capacity threshold may be set according to actual requirements, and specifically, the preset load capacity threshold may be 10, 20, 50, and so on.

The preset availability status may also refer to the network connectivity of the storage node being above a preset network connectivity threshold and the load capacity being above a preset load capacity threshold.

For the method for acquiring the geographic position of the internet of things device, in one possible implementation manner, the internet of things management platform can acquire the internet of things device sending the file transmission request according to the source of the received file transmission request, and locate the internet of things device to acquire the geographic position of the internet of things device.

In another possible implementation manner, the file transmission request sent by the internet of things device includes an IP address of the internet of things device, and the internet of things management platform may obtain, according to the IP address of the internet of things device included in the file transmission request, a geographic location where the internet of things device is located.

For determining the target storage node, in a possible implementation manner, the available storage nodes with the distance between the located area and the geographic position of the internet of things device meeting the preset condition can be screened out from a plurality of storage nodes, and then the target storage node with the located state being the preset available state is determined from the available storage nodes. In another possible implementation manner, an available storage node with a preset available state is selected from a plurality of storage nodes, and then a target storage node with a distance between a located area and the geographic position of the internet of things device meeting a preset condition is determined from the available storage nodes.

An embodiment of screening a plurality of storage nodes according to a distance between an area where the storage nodes are located and a geographic location of the internet of things device will be described in detail below.

And taking the storage node with the distance between the area where the storage node is located and the geographic position of the Internet of things equipment meeting the preset condition as an available storage node, and placing the available storage node in an available storage node list. The available storage nodes can be arranged into an available storage node list from near to far according to the distance between the available storage nodes and the geographic position of the Internet of things equipment, can be arranged into an available storage node list from far to near according to the distance between the available storage nodes and the geographic position of the Internet of things equipment, and can be randomly arranged into the available storage node list.

Judging whether the state of each available storage node is a preset available state according to the sequence in the available storage node list, if the state of a certain available storage node is not the preset available state, deleting the available storage node in the available storage node list, and judging whether the state of the next available storage node of the available storage node in the available storage node list is the preset available state; and if the state of a certain available storage node is a preset available state, taking the available storage node as a target storage node.

According to the method and the device for storing the file, the distance between the storage node and the geographic position of the Internet of things equipment is determined to meet the preset condition, and the storage node in the preset available state is used as the target storage node, so that the storage node which is relatively close to the Internet of things equipment and has relatively good network connectivity and relatively strong load capacity can be used as the target storage node, the stability of the determined target storage node is relatively good, file transmission failure caused by network fluctuation, relatively large files and other problems is not easy to occur during file transmission, the availability of the storage node is improved, and the failure rate of file transmission of the Internet of things equipment is reduced.

In another possible embodiment, a storage node preconfigured for the internet of things device may be determined as the target storage node.

Specifically, a user can pre-configure a storage node for an internet of things device on an internet of things management platform, and when the internet of things management platform receives a file transmission request sent by the internet of things device, the storage node pre-configured by the user for the internet of things device can be used as a target storage node, and meanwhile, the storage node number of the target storage node can be obtained. The internet of things management platform can acquire the address and access protocol of the target storage node according to the storage node number.

By adopting the embodiment, the Internet of things equipment can transmit the file to the target storage node appointed by the user, so that the requirement of the user is met, and meanwhile, the Internet of things management platform transmits the address and the access protocol of the target storage node to the Internet of things equipment, so that the Internet of things equipment and the storage node are not bound, the decoupling of the Internet of things equipment and the storage node is realized, and the integration complexity of the Internet of things equipment is reduced.

When the internet of things device needs to transmit files, the file transmission function of the internet of things device is required to be in an open state, and the internet of things management platform is required to open file transmission permission for the internet of things device. Therefore, the user needs to open file transmission rights for the internet of things equipment needing file transmission at the internet of things management platform, and if the user has the requirement of designating a storage node, the storage node can be designated for the internet of things equipment when the file transmission rights are opened for the internet of things equipment, namely, the storage node is preconfigured for the internet of things equipment.

The storage node designated by the user for the internet of things device is the storage node 2, and after receiving the file transmission request sent by the internet of things device, the internet of things management platform may use the storage node 2 as a target storage node, obtain the address and the access protocol of the storage node 2, and send the address and the access protocol of the storage node 2 to the internet of things device, so that the internet of things device may access the address of the storage node 2 by using the access protocol of the storage node 2, establish a communication connection with the storage node 2, and transmit the file to the storage node 2 through the communication connection. At the moment, the files required to be transmitted by the Internet of things equipment can be transmitted to the storage node preconfigured by the user, so that the requirements of the user are met.

In a possible implementation manner, after the storage node preconfigured by the user for the internet of things device is obtained, the internet of things management platform can also judge whether the state of the preconfigured storage node is a preset available state, if so, the preconfigured storage node is used as a target storage node; if not, taking the storage node which has the distance with the geographic position meeting the preset condition and is in the preset available state as the target storage node.

After the file transmission permission of the Internet of things equipment is opened, the Internet of things management platform sends an instruction for opening a file transmission function to the Internet of things equipment; after receiving an instruction for starting a file transmission function, the internet of things device sets a switch state of the file transmission function to be an on state, persists the switch state, stores the switch state to a nonvolatile memory, and prevents the switch state from being lost after the internet of things device is powered off and restarted.

However, when the user does not open the file transmission right for a certain internet of things device at the internet of things management platform, the file transmission function of the internet of things device may be in an open state, and then the internet of things device may also send a file transmission request to the internet of things management platform.

S201, receiving a file transmission request sent by the Internet of things equipment.

S202, if the Internet of things equipment opens the file transmission permission, executing the step of responding to the file transmission request and acquiring the address and the access protocol of the target storage node.

Specifically, when the internet of things management platform determines that the internet of things device opens the file transmission permission, the foregoing step S102 is executed, and a target storage node is determined for the internet of things device, so that the internet of things device can transmit the file to the target storage node.

S203, if the Internet of things device does not open the file transmission permission, the error code is sent to the Internet of things device, so that the Internet of things device responds to the error code to close the file transmission function of the Internet of things device.

It can be understood that when the internet of things device sends a file transmission request to the internet of things management platform, the internet of things device sends the file transmission request to the internet of things management platform at intervals of preset time, so that the internet of things management platform can receive the file transmission request and respond. Therefore, under the condition that the internet of things management platform judges that the internet of things equipment does not open the file transmission permission, the internet of things management platform also responds to the file transmission request of the internet of things equipment and sends error codes to the internet of things equipment so that the internet of things equipment can close the file transmission function of the internet of things equipment, and the problem that the internet of things equipment always sends an invalid file transmission request to the internet of things management platform is avoided.

By adopting the embodiment, the target storage node can be determined for the internet of things equipment under the condition that the internet of things equipment opens the file transmission permission, so that the internet of things equipment can transmit the file to the target storage node, and the internet of things equipment which does not open the file transmission permission is prevented from transmitting the file. Meanwhile, under the condition that the internet of things equipment does not open the file transmission permission, the error code is sent to the internet of things equipment in response to the file transmission request of the internet of things equipment, so that the internet of things equipment closes the file transmission function of the internet of things equipment, and the internet of things equipment is prevented from always sending an invalid file transmission request to the internet of things management platform.
