at least one internet of things device 13 is connected with the internet of things gateway 11 through an event bus EventBus so as to send data acquired by a sensor of the device to the internet of things gateway 11 through the EventBus.
The internet of things gateway 11 sends the data received through the EventBus to the cloud platform 12.
It should be understood that the cloud platform refers to a platform system providing cloud services, and the cloud services can be provided externally. In this embodiment, the cloud platform 12 summarizes data collected by the sensors of the internet of things device 13 to provide cloud services to the outside.
The Internet of things system of the embodiment of the application sends sensor data of different Internet of things devices to the cloud platform through the Internet of things gateway in a unified mode through the software architecture of the EventBus, so that cloud services provided by the cloud platform are coupled with sensors of the Internet of things devices, and maximum multiplexing on a hardware structure is achieved. Based on EventBus, on one hand, sensor data of different Internet of things devices can be processed uniformly, and the burden of a cloud platform is reduced; on the other hand, when a new sensor is added subsequently, interface application does not need to be developed independently for the new sensor, so that the expansion is more convenient and flexible.
The following describes the internet of things system according to the embodiment of the present application in detail.
As shown in fig. 2, in the internet of things system according to the embodiment of the present application, through a software architecture of EventBus, data collected by sensors of different internet of things devices are uniformly sent to the cloud platform 12 through the internet of things gateway 11 (intelligent sensing hub) and are summarized by the cloud platform 12, so as to provide a relevant cloud service.
The SensorHub has at least one communication protocol interface, such as an MQTT interface for message queue telemetry transmission, a TCP interface for transmission control protocol, an IPC interface for interprocess communication, a UART interface for universal asynchronous transceiver, a Bluetooth interface, a serial interface, etc. Each communication protocol interface is connected with a sensor supporting a corresponding communication protocol in a plurality of Internet of things devices. Namely, the internet of things system of the embodiment of the application realizes coupling multiplexing of different types of sensors through one SensorHub.
In particular, the software architecture of EventBus can extend more functional nodes to achieve more functions. By way of exemplary introduction, these functional nodes may include:
and the data monitoring node 14 is used for monitoring data in the designated Internet of things system. The cloud platform can control the data monitoring node 14 to monitor processes, performance indexes and the like in each system through the SensorHub.
And the firmware updating node 15 is used for updating the firmware of the internet of things system. The cloud platform can control the firmware update node 15 to download the latest firmware program through the SensorHub and perform updating.
The data processing node 16 performs a structuring process on data that needs to be sent to the cloud platform by the SensorHub, so that the SensorHub sends the structured data to the cloud platform 12, thereby avoiding a large amount of raw sensor data from being put on the cloud platform 103 side for preprocessing, and increasing the load of the cloud platform 103. Wherein, the above-mentioned structuring process can be but is not limited to at least one of the following ways:
(1) and cleaning the non-required data and deleting the unnecessary part in the data.
(2) And (4) cleaning format error data, and correcting or deleting parts which do not meet the format requirement in the data.
(3) And (4) logical error data cleaning, and data deduplication, deletion or correction of parts with contradiction.
(4) Necessary data supplement is carried out, and necessary parts missing in the data are reasonably filled.
It should be understood that the functional nodes in the EventBus may be configured individually according to the actual requirement of the internet of things system, and are not limited to the example in fig. 2, and are not described in detail herein for an example.
In addition, the EventBus can also be provided with an external interface 17, and the external interface 17 is connected with the SensorHub based on an interface agent program APIAgent. An external application integrated with an application programming interface can access the APIAgent in EventBus, and the APIAgent acquires data of the cloud platform 12 through the SensorHub and provides the data to the external application. That is, in the embodiment of the present specification, the cloud platform 12 can provide the cloud service to the outside through the APIAgent.
In addition, in order to guarantee the security of the internet of things system, the SensorHub can be used as a data channel unique to a cloud platform. Namely, the sensors of any internet of things device, the functional nodes of the EventBus and the external interfaces need to acquire data exposed by the cloud platform 12 through the SensorHub. Furthermore, the EventBus can also realize the encryption of transmission data based on a security transport layer protocol (TLS) encryption algorithm so as to reduce the possibility of data leakage of the cloud platform.
On the basis, the EventBus can also be configured with protocols to assist the modules to work cooperatively. By way of exemplary introduction, these protocols may include:
and Remote Procedure Call (RPC) protocol to realize remote call among the functional nodes.
And issuing-subscribing a Pub-Sub protocol to realize information sharing among the functional nodes.
And the Broadcast protocol realizes the transmission of Broadcast messages among the functional nodes.
The event drives a RemoteEvent protocol, and realizes the control of calling SensorHub by the functional node and the external interface.
The AutoDiscovery protocol is automatically displayed, the validity check of the functional node newly accessed to the EventBus is realized (for example, the account and the password provided by the newly accessed functional node are checked), and the communication address is configured for the functional node which is not newly accessed after the validity check is passed.
To sum up, the internet of things system of the embodiment of the application accesses sensor data of different internet of things devices to SensorHub in a unified multiplexing mode through the Eventbus. The SensorHub can be regarded as a central link of the Internet of things system, and each functional node set by the Eventbus can realize general processing on sensor data of each type through the SensorHub, so that an application program does not need to be developed additionally. Under the software framework of EventBus, each sensor has no direct dependency relationship, so that the Internet of things system has the characteristic of loose coupling. In addition, the SensorHub is used as the only data channel of the cloud platform, so that the platform data can be minimized to be exposed to the outside, and the risk of the cloud platform being attacked by hackers is effectively reduced based on the TLS encryption data transmission technology configured by Eventbus.
