Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.

It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.

Example one

Fig. 1 is a flowchart of a data processing method based on the internet of things according to an embodiment of the present invention, where the embodiment is applicable to a case where a platform of the internet of things implements data interaction through a subscription relationship between a subscription application and a subscribed device, and the method may be executed by a data processing apparatus based on the internet of things, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a server, as shown in fig. 1, the method includes the following operations:

s110, establishing a subscription relation between a subscription application and subscribed equipment; the subscribed device is an unbound device corresponding to the subscribed application.

The subscription can be that any application establishes an association relationship with an unbound device or other applications. The subscription application may be one that performs data information collection and manipulation on the unbound devices. The application can be internet of things application, namely various applications directly used by a user, such as intelligent control, security, electric meter reading, telemedicine or intelligent agriculture and the like. The application type is not particularly limited in the embodiment of the present invention. The subscribed device may be a device subscribed to by the subscribed application, the device being an unbound device under the subscribed application. So-called unbound devices, i.e. devices and applications, do not establish a binding relationship. Accordingly, the subscription application can collect and operate data information of the subscribed device according to the subscription authority. The subscription relationship may be an association relationship between the subscribing application and the corresponding subscribed device. The association relationship is different from the binding relationship, and only represents that data interaction can be performed between the subscribing application and the subscribed device according to certain authority. That is, the subscribing application has all device operation rights for the binding device with which the binding relationship is established, and the subscribed device with which the subscribing application establishes the subscription relationship has a part of device operation rights, which can be specified when the subscription relationship is established. The Internet of things platform is characterized in that any object is connected with a network through information sensing equipment according to an agreed protocol, and the object performs information exchange and communication through an information transmission medium so as to realize functions of intelligent identification, positioning, tracking, supervision and the like. The Internet of things platform can provide safe and reliable connection communication capacity for equipment, downwards connect mass equipment and support equipment data acquisition and cloud-up; and an Application Programming Interface (API) is provided upwards, and the server issues the command to the equipment end by calling the API, so that remote control is realized. Meanwhile, the Internet of things platform also provides other value-added capabilities such as equipment management, rule engines and the like, and enables various IoT scenes and industry developers. In the embodiment of the invention, if the application performs data interaction on some devices which do not establish a binding relationship with the application, the application needs to be used as a subscription application, and a subscription relationship between the subscription application and a subscribed device can be established through an internet of things platform.

And S120, establishing data interaction between the subscription application and the subscribed device based on the subscription relation. Correspondingly, after the subscription relationship is established between the subscription application and the subscribed device, data interaction can be performed between the subscription application and the subscribed device according to the subscription authority. That is, the subscribing application has an operation right on the subscribed device according to the subscription relationship, the subscribing application can perform data information acquisition operation on the subscribed device, and the subscribed device can feed back data information to the subscribing application according to the subscription relationship.

Therefore, the subscription relation between the subscription application and the subscribed equipment is established, the subscription application can perform data interaction with the subscribed equipment, the limitation that the application can only perform data interaction with the equipment with the binding relation in the traditional Internet of things platform is broken, the data processing of the Internet of things is more flexible, and flexible and variable business requirements are met.

Example two

Fig. 2 is a flowchart of a data processing method based on the internet of things according to a second embodiment of the present invention, which is embodied on the basis of the foregoing embodiment, and in this embodiment, a specific optional implementation is provided for establishing data interaction between the subscription application and the subscribed device based on the subscription relationship, and accordingly, as shown in fig. 2, the method includes the following operations:

s210, establishing a subscription relationship between the subscription application and the subscribed equipment; the subscribed device is an unbound device corresponding to the subscribed application.

In an optional embodiment of the present invention, establishing a subscription relationship between the subscribing application and the subscribed device may include: determining a subscribing application and a subscribed application; screening a target device operation type from a device operation type set included by the subscribed application; and establishing a subscription relation between the subscription application and the operation type of the target equipment.

The subscribed application may be an application having a binding relationship with a subscribed device corresponding to the subscribing application. The device operation type set may be an operation type set for performing different operation attribute types on the device, and the device operation type set may include at least one operation attribute type, where each operation attribute type is associated with multiple devices. For example, assuming that the operation attribute type is "on temperature monitoring", the operation attribute type may turn on a temperature monitoring function for all devices capable of performing temperature monitoring. That is, a plurality of devices that can perform temperature monitoring are associated with the operation attribute type of "on temperature monitoring". The target device operation type may be one or more operation attribute types that are filtered out of a set of device operation types.

Optionally, when the subscription relationship between the subscribing application and the subscribed device is established, an optional manner is to first determine the subscribing application and the subscribed device. And then screening the target device operation type from the device operation type set included by the subscribed application to establish a subscription relationship between the subscribing application and the target device operation type. When a subscription relationship exists between the subscription application and the operation type of the target device, the subscription relationship is equivalent to the subscription relationship existing between the subscription application and the device associated with the operation type of the target device.

Fig. 3 is a schematic effect diagram of an internet of things platform management application interface according to a second embodiment of the present invention. In a specific example, when the subscription relationship is established through the internet of things platform, an "application subscription" function of the internet of things platform management application interface may be triggered, and an application subscription new interface obtained after the triggering is shown in fig. 3. In the application subscription new adding interface, a subscription application and a subscribed application can be selected autonomously. Assume that the subscribing application is application a and the subscribed application is application B. The device specification is also a device operation type set, and correspondingly, all the specifications may be all the device operation types included in the device operation type set included in the application B. The custom specification may be one or more device operation types selected from a set of device operation types. When all the specifications are selected, the application A subscribes to the whole device operation type set included by the application B. Accordingly, the devices associated under the whole set of device operation types become subscribed devices of the application a.

Fig. 4 is a schematic diagram illustrating a target device operation type screening according to a second embodiment of the present invention. As shown in fig. 4, the subscribing application is application a and the subscribed application is application B. It is assumed that the device operation type set included in the application B includes a data read type, a data delete type, and a data change type. And if the operation type of the target equipment of the application A needing to subscribe the application B is the data reading type, selecting the data reading type through the custom specification. If the operation type of the target device is the data change type, the application A screens the data change type from the device operation type set of the application B as the operation type of the target device, and then the application A establishes a subscription relationship with the selected operation type of the target device. If the operation type of the target device is data change, the application A screens out the data change type from the device operation type set of the application B as the operation type of the target device, and then the subscription application A establishes a subscription relationship with the selected operation type of the target device.

And S220, determining the target subscription equipment according to the operation type of the target equipment.

The target subscribing device may be a device capable of performing a target device operation type operation, and the target subscribing device may be one or more devices.

Correspondingly, after the operation type of the target device is determined, the device associated with the operation type of the target device can be further determined according to the operation type of the target device, and the target subscription device is determined from the associated devices as the subscribed device.

For example, assume that the subscribed application B has three bound devices, B1, B2, and B3. The devices capable of performing data reading type operation are b1 and b2, the devices capable of performing data deleting type operation are b1, b2 and b3, and the devices capable of performing data changing type operation are b2 and b 3. If the operation type of the target device is the data reading type, since the devices capable of performing the data reading type operation are b1 and b2, it may be determined that the target subscribing device may be b1 and/or b2 according to the operation type of the target device.

And S230, establishing a subscription relation between the subscription application and the target subscription equipment. Specifically, if a specific specified device needs to be subscribed, the target device operation type may be screened from the device operation type set included in the subscribed application, and then the target subscribed device is determined according to the target device operation type, so as to establish a subscription relationship between the subscription application and the target subscribed device.

For example, assuming that the application a is a subscribing application, the device B1 is a target subscribing device, and the application B is a subscribed application, a specific process of establishing a subscription relationship between the application a and the device B1 may include: and screening out the operation type of the target device from the operation type set of the devices included in the application B. And when the operation type of the target equipment is the data reading type, establishing a subscription relation between the application A and the data reading type. Since the devices capable of performing the data reading type operation are b1 and b2, that is, the target subscribing device can be determined to be b1 and/or b2 according to the operation type of the target device. A subscription relationship between application a and device b1 may be established.

Accordingly, S230 may specifically include the following operations:

s231, determining the type of the subscription event matched between the subscription application and the target subscription equipment.

The event may be one of the functional models of the device or an event during the running of the device, and the event may generally include notification information that needs to be sensed and processed externally, or may include a plurality of output parameters. For example, information on the completion of a certain task, the temperature at which the device has failed or has been alerted, etc. Events may be subscribed to and reported. The subscription event type may be an event type for which the subscription application needs to have an operation right to the target subscription device.

Specifically, the internet of things platform may first determine a subscription event type that the subscription application matches the target subscription device. That is, the operation authority of the subscription application on the target subscription device can be set through the internet of things platform.

S232, establishing a subscription relationship between the subscription application and the target subscription equipment according to the subscription event type.

The subscription event type may include, but is not limited to, a device alarm event, a device attachment upload event, a device attachment download event, a device status reporting event, a device location reporting event, and a device activation event.

The device alarm event may be an alarm event autonomously reported by the target subscription device. The device attachment upload event may be a device attachment upload event of the target subscribing device. The device accessory download event can be a device accessory download event of the target subscribing device. The device state reporting event may be a device state reporting event of the target subscribing device. The device location reporting event may be a device location reporting event of the target subscribing device. The device activation event may be an activation event of the target subscribing device. That is, whatever information the device may produce may act upon to singulate the subscription event type for interaction with the subscription application.

For example, the subscription event type may specifically include the following event types:

the device reports the message event: the message reported by the device may include custom data and physical model data (including attribute reporting, event reporting, attribute setting response, and service invocation response) reported by the device. Device state change notification event: when the state of the equipment under the product changes, the system sends out a notification message. Such as device offline messages. Device lifecycle change event: including notification messages for device creation, deletion, disabling and enabling, among other flexible notifications. Reporting events of the object model historical data: namely, the device reports the attribute and the event history data. Firmware upgrade status notification event: namely reporting the notification messages of success or failure of firmware upgrade. The gateway discovers that the sub-equipment reports events: the gateway can report the discovered information of the sub-devices to the platform of the Internet of things, and the event needs to be supported by an application program on the gateway and belongs to a specific message type of a gateway product. Device topology relationship change events: refers to the topological relation establishment and release messages between the kid device and the gateway. The gateway product specific message type.

Correspondingly, after the internet of things platform determines the subscription event type matched with the target subscription device, the subscription relationship between the subscription application and the target subscription device is established according to the subscription event type. It is understood that the subscribing application may subscribe to all event types of the subscribed device, or may subscribe to only a portion of event types of the subscribed device. That is, the subscribing application may subscribe to all the operation permissions of the subscribed device, or may subscribe to only part of the operation permissions of the subscribed device. Correspondingly, after the subscription event type to which the subscription application needs to subscribe is determined, the association relationship between the subscription application and the target subscription device can be established according to the subscription event type.

For example, assuming that the type of the subscription event determined by the subscription application and the target subscription device is a device state reporting event, that is, the subscription application only has an operation right for the device state reporting event of the subscribed device, an association relationship between the subscription application and the target subscription device may be established according to the device state reporting event. When the subscribed device needs to report the device state to the bound application, the device state can be reported to the subscribed application at the same time.

Fig. 5 is a schematic diagram illustrating an interface effect of determining a type of a subscription event for a target subscribing device according to a second embodiment of the present invention. As shown in fig. 5, if the target subscribing device that needs to establish a subscription relationship with the subscribing application is device b1, device b1 is selected as the target subscribing device by selecting the custom device. As shown in fig. 5, after the custom device is selected, the virtual function key of the add device may be triggered, and then the selection interface of the target subscription device shown in fig. 6 pops up. Fig. 6 is a schematic diagram illustrating an effect of a selection interface of a target subscription device according to a second embodiment of the present invention. The target subscribing device can be searched out through the keyword. The keyword may be a target subscription device ID or a target subscription device name. After the ID or the name of the target subscription device is input, the query can be clicked, and the target subscription device is selected in the query list. For example, the ID of device b1 may be searched, adding device b1 as the target subscribing device in the query list. All event types under the event category are selected if a subscription to all subscribed event types is required for the target subscribing device b 1. Optionally, the target subscribing device can be one or more. The custom event type under the event category is selected if a partial subscription to the event type is required for the target subscribing device b 1. One or more of the custom event types may be selected. If all the devices are selected to have a certain subscription event type, the fact that the certain subscription event type of all the devices is subscribed by the subscription application is indicated.

S240, determining an instruction issuing type matched with the subscription application and the subscription event type; the instruction issuing type comprises an equipment state obtaining instruction, an equipment information obtaining instruction and an equipment control instruction.

The device state obtaining instruction may be used to obtain a device state, where the device state may be, for example, a state of turning on the device, running the device, turning off the device, or whether the device is running normally. The device information obtaining instruction may be used to obtain device information, and the device information may be, for example, device operation information, or device specific parameters. The embodiment of the present invention does not specifically limit the device status and the specific content of the device information. The device control instruction is used to perform function control on the device, such as controlling and adjusting the temperature or the turn-on time of the device, and the embodiment of the present invention also does not limit the specific type of the device function control.

Specifically, after the subscription relationship between the subscription application and the target subscription device is established according to the subscription event type, the instruction issuing type matching the subscription application and the subscription event type may be determined. For example, if the determined instruction issuing type is the device state acquisition instruction, the subscribing application and the subscribed device can only perform data interaction through the device state acquisition instruction. If the determined instruction issuing type is an equipment control instruction, the subscription application can control one or more functions of the target subscription equipment through the equipment control instruction.

And S250, establishing data interaction between the subscription application and the subscribed device based on the subscription relation.

Illustratively, the subscribing application establishes a subscription relationship with the subscribed device, obtains device data in the subscribed device matching with the instruction issuing type according to the instruction issuing type, and the subscribed device sends the device data matching with the instruction issuing type to the subscribing application, that is, completes data interaction between the subscribing application and the subscribed device.

It should be noted that the subscribing application can perform data interaction with all data types generated by the subscribed device based on the subscription relationship. For example, the subscription application may view device information of the subscribed device, and may specifically view device basic information, which includes device certificate information, firmware information, extension information, tag information, and other information. The subscription application may also view device data of the subscribed device, such as viewing a current attribute value reported by the device, viewing an event record reported by the device, viewing a device service invocation record, and the like. The subscription application may also view a device log of the subscribed device, such as a cloud run log, a device local log, and the like. The subscribing application may also view the device groupings of the subscribed devices, specifically may view grouping information for the devices, and may also add the device to the groupings to add the device to existing groupings. In addition to the data interaction function for viewing data, the method and the device for viewing data can also achieve device function control, control conditions of the associated application of the receiving device on the device, data actively reported by the receiving device, and the like.

In an optional embodiment of the present invention, establishing data interaction between the subscribing application and the subscribed device based on the subscription relationship may include: receiving a device issuing instruction sent by a subscription application; and issuing the issuing equipment instruction to the subscribed equipment.

The device issuing instruction may be an instruction issued by the subscription application to the subscribed device. For example, the issued device command may be a device status acquisition command and/or a device information acquisition command.

In an alternative embodiment, the data interaction scenario between the subscribing application and the subscribed device may be: and the Internet of things platform receives the equipment issuing instruction sent by the subscription application, and then issues the equipment issuing instruction to the subscribed equipment. For example, if the device issuing instruction sent by the subscription application is a device state obtaining instruction, the device state obtaining instruction is issued to the subscribed device through the internet of things platform.

In this embodiment of the present invention, before issuing the issuing device instruction to the subscribed device, the method may further include: determining an application subscription rule matched with the subscription application; performing authority verification on the issued device instruction according to the application subscription rule; issuing the issuing device instruction to the subscribed device may include: and if the permission check is determined to pass, issuing a device instruction to the subscribed device.

The subscription rule may be a subscription relationship between the subscription application and the subscribed device, and the permission check may be to determine whether an operation permission exists for the subscribed device in an equipment issuing instruction sent by the subscription application according to the subscription rule.

Specifically, after receiving an equipment issuing instruction sent by a subscription application, the internet of things platform performs authority verification on the operation authority of the equipment issuing instruction according to a subscription relationship, namely a subscription rule, between the subscription application and the subscribed equipment. If the authority verification is confirmed to pass, issuing a device instruction to the subscribed device; otherwise, determining that the issuing equipment instruction has no operation authority on the subscribed equipment, and refusing to issue the issuing equipment instruction to the subscribed equipment.

Fig. 7 is a schematic flowchart of data interaction between a subscribing application and a subscribed device through a device issuing instruction according to a second embodiment of the present invention. In a specific example, as shown in fig. 7, it is assumed that the subscribing application is application a and the subscribed device is device b 1. One of the data interaction scenarios of application a and device b1 may be: the internet of things platform receives an issuing device instruction sent by an application A through an application programming interface (Restful API, restAPI, a rule to be followed when establishing the API) of a Rest architecture specification, and then performs permission verification on the issuing device instruction according to subscription rules of a subscription application and a subscribed device, wherein the subscription rules of the subscription application and the subscribed device can be simply referred to as configuration rules. Assuming that the issued device command is a device state acquisition command, if the device b1 is the target subscription device subscribed by the application a and the application a subscribes to the device b1 state acquisition event, it indicates that the permission check is passed. At this time, the internet of things platform may issue the issued device instruction to an open-source internet of things MQTT Message server (inlang/Enterprise/Elastic MQTT Broker, EMQ) through Message Queue Telemetry Transport (MQTT), so as to issue the issued device instruction to the subscribed device b1 through EMQ. It can be understood that, after receiving the issued device command, the device b1 may respond to the issued device command and feed back the response data to the application a, thereby completing the complete data interaction process between the application a and the device b 1.

In an optional embodiment of the present invention, establishing data interaction between the subscribing application and the subscribed device based on the subscription relationship may include: receiving issuing instruction data of the associated application of the subscribed equipment; and feeding back the issued instruction data to the subscription application.

Wherein, the associated application can be an application having a binding relationship with the subscribed device. The issuing instruction data may be instruction data sent by the associated application to the subscribed device, and may include, but is not limited to, issuing instruction operation data and issuing instruction response data. The issuing instruction operation data may be instruction operation data that is sent to the binding device by the associated application, and the issuing instruction operation data may include an acquisition device state acquisition instruction and/or a device information acquisition instruction, and the like. The issuing instruction response data may be instruction response data fed back to the associated application by the binding device for the issuing instruction operation data, that is, an execution result of the subscribed device on the issuing instruction data of the associated application.

Correspondingly, the internet of things platform can receive the issuing instruction operation data sent by the associated application and feed the issuing instruction operation data back to the subscription application with the subscription relation with the subscribed equipment. Meanwhile, after the subscribed device generates issuing instruction response data according to the issuing instruction operation data and sends the issuing instruction response data to the Internet of things platform, the Internet of things platform can also feed the issuing instruction response data back to the subscription application. That is, as long as the subscribing application has the corresponding authority, the data interaction condition between the associated application and the subscribed device can be obtained through the internet of things platform.

Fig. 8 is a schematic flowchart of a process of performing information interaction between a subscription application and an associated application by issuing instruction data according to a second embodiment of the present invention. As shown in fig. 8, the internet of things platform receives the issue instruction data sent by the application B through RestAPI, and the outbound handler in the internet of things platform sends the issue instruction data (i.e., the instruction operation message in fig. 8) to the application a through the subscription rule. The outbound processor can be a module for sending messages to the outside by the platform of the internet of things. The issuing instruction data sent by the internet of things platform to the application A can be issuing instruction operation data sent by the application B to the internet of things platform and issuing instruction response data fed back by the subscribed equipment to the issuing instruction operation data. And simultaneously, the Internet of things platform feeds back the order issuing response data fed back by the subscribed equipment aiming at the order issuing data of the application B to the application B.

In this embodiment of the present invention, if the issue instruction data is issue instruction response data, before feeding back the issue instruction data to the subscription application, the method may further include: performing data filtering processing on the issued instruction response data to obtain filtering instruction response data; determining target instruction response data according to the application subscription rule and the filtering instruction response data; and feeding back the target instruction response data to the subscription application according to the data communication protocol.

The data filtering process can be a filtering operation of the internet of things platform for carrying out error data or invalid data on the issued instruction response data. The filtering instruction response data may be data obtained by performing data filtering processing on the issued instruction response data. The target order response data may be filter order response data that matches the subscription rules. The data communication protocol may be a set of conventions that are set forth to ensure efficient and reliable communication between two parties communicating in the data communication network. These conventions may include the format, sequence and rate of data, the acknowledgement or rejection of data transmission, error detection, retransmission control and inquiry operations, and the embodiments of the present invention are not limited to the content of the data communication protocol.

In an alternative embodiment, one data interaction scenario between the subscribing application and the subscribed device may be: the Internet of things platform receives issuing instruction data sent by the associated application of the subscribed equipment, the subscribed equipment responds to the issuing instruction, data filtering processing is carried out on the instruction response data of the subscribed equipment to obtain filtering instruction response data, and the filtering instruction response data matched with the subscription rule, namely target instruction response data, is determined. Then, the internet of things platform can feed the target instruction response data back to the subscription application according to the data communication protocol and the subscription rule.

Fig. 9 is a schematic flowchart of data interaction between a subscription application and a subscribed device through issuing instruction data according to a second embodiment of the present invention. As shown in fig. 9, it is assumed that the subscribing application is application a, the associated application is application B, and the subscribed device is device B1. And the Internet of things platform receives the issuing instruction operation data sent by the application B through RestAPI and sends the issuing instruction operation data to the device B1 through EMQ. When the device b1 generates issuing instruction response data for the issuing instruction operation data, the issuing instruction response data is sent to the internet of things platform through the EMQ. And after receiving the issued instruction response data, the Internet of things platform processes the issued instruction response data by using the outbound processor. Specifically, the outbound processor may perform data filtering processing on the issued instruction response data to obtain filtered instruction response data. And performing data weight distribution on the response data of the filtering instruction. Data distribution refers to that data which can be accessed or inquired by applications with different rights is different. The data right distribution process may determine which of the issued instruction response data is data for which the subscription application has access or query authority according to a subscription rule, that is, a configuration rule shown in fig. 9, and then send the data for which the subscription application has access or query authority to the subscription application. Assuming that a subscription relationship exists between the application a and the device b1, and the application a has all operation rights to the device b1, it is determined that the rights check is passed, and the application a has an access right to the issued command response data sent by the device b 1. The entire filter instruction response data can be used as the target instruction response data. Assuming that a subscription relationship exists between the application a and the device b1, but the application a has a partial operation authority on the device b1, at this time, the authority check is performed on the configuration rule of the application a, when part or all of the data in the filter instruction response data matches the subscription event type of the application a on the device b1, it is determined that the authority check passes, and partial data matching the subscription event type of the application a on the device b1 is screened out from the filter instruction response data as target instruction response data. After the target instruction response data is determined, the internet of things platform can convert the data format of the target instruction response data according to a data communication protocol, wherein the data communication protocol is short for data protocol. Then, the target instruction response data subjected to the data format conversion is fed back to the application a. Because the application B and the device B1 are in a binding relationship, and the instruction response data is corresponding data of the instruction issuing operation data sent by the application B, the internet of things platform can directly and completely send the filtering instruction response data to the application B through data format conversion.

In an optional embodiment of the present invention, establishing data interaction between the subscribing application and the subscribed device based on the subscription relationship may include: receiving a device reporting event sent by a subscribed device; and feeding back the event reported by the equipment to the subscription application.

The device reporting event may be an event reported by the subscribed device to the subscribing application. For example, the device reporting event may include a device alarm event, a device status reporting event, a device location reporting event, and the like.

Correspondingly, the internet of things platform can receive the equipment reporting event sent by the subscribed equipment, and then feed back the equipment reporting event to the subscription application according to the subscription rule.

In this embodiment of the present invention, before feeding back the event reported by the device to the subscription application, the method may further include: performing data filtering processing on the equipment reporting event to obtain filtered reporting event data; determining target reporting event data according to the application subscription rule and the filtered reporting event data; and feeding back the target reported event data to the subscription application according to the data communication protocol.

The target reporting event data may be filtered reporting event data matched with the subscription rule.

In an alternative embodiment, one data interaction scenario between the subscribing application and the subscribed device may be: and the Internet of things platform receives the equipment reporting event sent by the subscribed equipment, performs data filtering processing on the equipment reporting event to obtain filtered reporting event data, and feeds back the filtered reporting event data matched with the subscription rule, namely the target reporting event data to the subscription application through a data communication protocol.

Fig. 10 is a schematic flowchart of a data interaction between a subscribing application and a subscribed device through a device reporting event according to a second embodiment of the present invention. As shown in fig. 10, assuming that the subscribed application is application a, device b1 is the target subscribing device to which application a subscribes. The device b1 sends the device reporting event to the application a, and the specific process may include: the device b1 sends the device reporting event to the EMQ, the EMQ sends the device reporting event to the Internet of things platform through the MQTT protocol, and the Internet of things platform performs data filtering processing on the device reporting event through the outbound processor to obtain filtered reporting event data. And then, performing data weight distribution on the filtered reported event data. Since the application a has the access right of the filtered reported event data, namely the target reported event data, matched with the subscription rule to the device b1, it is determined that the right check is passed, and further, the data format conversion is performed on the target reported event data according to the data communication protocol, and the conversion result is fed back to the subscription application.

Fig. 11 is a schematic system architecture diagram of a data processing method of the internet of things according to a second embodiment of the present invention. As shown in fig. 11, the application layer calls the RestAPI interface to communicate with the internet of things platform, the internet of things platform communicates with the EMQ through MQTT, and the device side can receive the command data issued by the application layer, issue the device command, or send the device report event to the application layer through the EMQ. The Internet of things platform is used as a transfer station for connecting communication, and can distribute authority for issuing instruction data, issuing equipment instructions and reporting events by equipment for applications and equipment related to subscription according to subscription rules. And the Internet of things platform performs data filtering and data distribution on the data fed back by the equipment terminal according to a subscription rule, namely a configuration rule, and finally feeds back the data to the application layer. The EMQ subscription topic may be multiple topics subscribed to the server by one device through the EMQ. The subscription subject may be issuing instruction data received by the device terminal or information corresponding to the issuing device instruction, or may be different device reporting events sent by the device terminal.

Therefore, by establishing the subscription relationship between the subscription application and the subscribed device, the subscription application can perform data interaction with the subscribed device, and the authority range of the application layer is expanded, wherein the authority range can include authorization between two applications, authorization between different applications of the same user, and authorization between different applications of the two users. The expansion of the application layer authority range enables the data processing of the Internet of things to be more flexible, so that flexible and changeable service requirements are met.

According to the embodiment of the invention, the subscription application distributes the equipment authority of the subscribed equipment according to the subscription rule, and the subscription application has partial operation authority on the subscribed equipment, such as equipment command issuing, response data checking of the issuing command, operation type screening and checking of the target equipment, equipment reporting events and the like. The problem that the existing Internet of things platform can only process data of applications and equipment with binding relations is solved, so that the single binding relation applied to the equipment is broken, and the control range of an application layer to an equipment end is expanded. The method and the device have the advantages that cross-application equipment operation, cross-application checking of issued instruction data sent to the equipment, cross-application uploading of reported event data by the equipment, subscription of checking and operation permission of specified equipment, subscription of specified equipment-side specified reported event data and the like are achieved, so that flexibility and expansibility of data processing of the Internet of things are improved, flexible and changeable business requirements are met, processing flow effects are enabled to be more convenient and faster, safety is higher, and cost is lower under the condition that the application side is changed slightly.
