Detailed Description

In order to make the technical scheme and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the detailed description is intended to illustrate the invention and is not intended to limit the scope of the invention.

For simplicity and clarity of description, the following description sets forth aspects of the invention by describing several exemplary embodiments. Numerous details in the embodiments are provided solely to aid in the understanding of the invention. It will be apparent, however, that the embodiments of the invention may be practiced without limitation to these specific details. Some embodiments are not described in detail in order to avoid unnecessarily obscuring aspects of the present invention, but rather only to present a framework. Hereinafter, "comprising" means "including but not limited to", "according to … …" means "according to at least … …, but not limited to only … …". The term "a" or "an" is used herein to refer to a number of components, either one or more, or at least one, unless otherwise specified.

Fig. 1 is an exemplary flowchart of a method for acquiring internet of things data according to the present invention.

As shown in fig. 1, the method includes:

step 101: each data acquisition component corresponding to the respective data type is enabled to acquire the internet of things data of the respective data type.

Here, each data acquisition component comprises a plurality of data acquisition protocols, wherein each data acquisition protocol corresponds to a respective internet of things data source of the plurality of internet of things data sources; the method further comprises the steps of: determining an Internet of things data source to which each data acquisition component is arranged; activating a data acquisition protocol which is contained in each data acquisition component and related to the data source of the Internet of things; and establishing a corresponding relation between the activated data acquisition protocol and the data type of the data source of the Internet of things.

It can be seen that each data acquisition component has the ability to acquire respective data from a plurality of internet of things data sources by including a plurality of data acquisition protocols. Moreover, based on the data acquisition component, the corresponding data acquisition protocol is activated based on the data source of the Internet of things, and the data of the Internet of things is acquired from the data source of the Internet of things by utilizing the activated data acquisition protocol, so that the universal data acquisition component is provided.

Specifically, the data acquisition protocol may include: a sensor acquisition protocol adapted to acquire sensor data from a sensor, a building acquisition protocol adapted to acquire building data from a building, a PLC acquisition protocol adapted to acquire PLC data from a PLC, a CNC acquisition protocol adapted to acquire CNC data from a CNC, and other acquisition protocols.

The foregoing exemplary description describes typical examples of data acquisition protocols, and those skilled in the art will recognize that such descriptions are merely exemplary and are not intended to limit the scope of embodiments of the present invention.

The data collection protocols in the data collection component corresponding to the particular arrangement of data sources of the internet of things may be activated by various embodiments. Such as:

embodiment (1), receiving, via a human-machine interface, a user instruction adapted to select a data acquisition protocol; selecting a data acquisition protocol from a plurality of data acquisition protocols based on a user instruction; the selected data acquisition protocol is activated. Accordingly, the corresponding data acquisition protocol may be activated based on the user instructions.

For example, assume that each data acquisition component contains a data acquisition protocol comprising: sensor acquisition protocol, building acquisition protocol, PLC acquisition protocol and CNC acquisition protocol. When a user extracts the data acquisition component at a warehouse where the data acquisition component is stored, the user does not know that the data source of the Internet of things is a sensor, but the data source of the Internet of things does not bring barriers to subsequent arrangement work. The user extracts a data acquisition component, wherein the data acquisition protocols in the data acquisition component are all in an inactive state. When a user arranges the data acquisition component at the sensor, the user can determine that the data source of the Internet of things is the sensor by visual observation, send a user instruction for selecting the sensor acquisition protocol through a human-computer interface, correspondingly activate the selected sensor acquisition protocol by the data acquisition component, and acquire data from the sensor by utilizing the sensor acquisition protocol.

(2) Receiving a handshake message containing an identifier of the data source of the Internet of things from the data source of the Internet of things; resolving an identification from the handshake message; selecting a data acquisition protocol based on the identification; the selected data acquisition protocol is activated. Thus, automated activation of the corresponding data acquisition protocol may be achieved based on the handshake message.

For example, assume that each data acquisition component contains a data acquisition protocol comprising: sensor acquisition protocol, building acquisition protocol, PLC acquisition protocol and CNC acquisition protocol. When a user extracts the data acquisition component at a storehouse where the data acquisition component is stored, the user does not know that the data source of the Internet of things is a PLC, but the data source does not bring barriers to subsequent arrangement work. The user extracts a data acquisition component, wherein the data acquisition protocols in the data acquisition component are all in an inactive state. When a user arranges the data acquisition component at the PLC, the PLC sends a handshake message containing the identification of the PLC to the data acquisition component. The data acquisition component analyzes the identification of the PLC from the handshake message, so that the fact that the data source of the Internet of things is the PLC can be determined, the data acquisition component correspondingly activates a PLC acquisition protocol, and the PLC acquisition protocol is utilized to acquire data from the PLC.

Step 102: each data acquisition component is enabled to respectively encapsulate the respectively acquired internet of things data into respective messages with the same message format.

Here, each data acquisition component encapsulates the respective acquired internet of things data into respective messages having the same message format, respectively.

Step 103: the respective messages are sent to the upstream interface protocol component via a message bus corresponding to the message format.

In one embodiment, the method further comprises: enabling the uplink interface protocol component to send the respective messages to the cloud or local server.

In one embodiment, the method further comprises: enabling the uplink interface protocol component to send the respective messages to the internet of things gateway, so that the internet of things gateway can send the respective messages to the cloud or local server.

In particular, the uplink interface protocol component may include a message queue telemetry transport (Message Queuing Telemetry Transport, MQTT) protocol, a hypertext transfer protocol (Hyper Text Transfer Protocol, HTTP), a hypertext transfer protocol with secure sockets layer (Hyper Text Transfer Protocol over Secure Socket Layer, HTTPs), a KAFKA protocol, a transmission control protocol (Transmission Control Protocol, TCP) or a user datagram protocol (User Datagram Protocol, UDP), and so forth.

While the above exemplary descriptions of typical examples of uplink interface protocols, those skilled in the art will recognize that this description is exemplary only and is not intended to limit the scope of embodiments of the present invention.

In fig. 2, the data acquisition layer 21 includes a sensor acquisition protocol 211, a building acquisition protocol 212, a PLC acquisition protocol 213, a CNC acquisition protocol 214, and other acquisition protocols 215. The sensor acquisition protocol 211 is adapted to acquire sensor data from the sensor; building acquisition protocol 212 is adapted to acquire building data from a building; the PLC acquisition protocol 213 is adapted to acquire PLC data from the PLC; the CNC acquisition protocol 214 is adapted to acquire CNC data from CNC; other acquisition protocols 215 are adapted to obtain data corresponding to other acquisition protocols 215 from other internet of things data sources.

The sensor acquisition protocol 211 encapsulates the sensor data as a first message based on the message format of the message bus 22; building collection protocol 212 encapsulates the building data as a second message based on the message format of message bus 22; the PLC acquisition protocol 213 encapsulates the PLC data into a third message based on the message format of the message bus 22; the CNC acquisition protocol 214 encapsulates the CNC data as a fourth message based on the message format of the message bus 22; other acquisition protocols 215 encapsulate other acquisition data into a fifth message based on the message format of message bus 22.

The message bus 22 sends the first message, the second message, the third message, the fourth message and the fifth message to the uplink interface protocol layer 23. The uplink interface protocol layer 23 contains MQTT protocol 231, HTTP/HTTPs protocol 232, KAFKA protocol 233, TCP/UDP protocol 234 and other uplink interface protocols 235. The user may send at least one message or all of the first message, the second message, the third message, the fourth message, and the fifth message by a specific uplink protocol in the uplink interface protocol layer 23 based on a preset determination. The uplink interface protocol layer 23 may directly transmit at least one message or all of the first message, the second message, the third message, the fourth message, and the fifth message to the cloud, the server, or any designated storage medium.

For example, when the user designates the cloud to receive the sensor data and the PLC data through the MQTT protocol 231 in the uplink interface protocol layer 23, the MQTT protocol 231 transmits the first message and the third message to the cloud via the message bus 22.

For another example, when the user specifies that the server receives CNC data via the KAFKA protocol 233 in the uplink interface protocol layer 23, the KAFKA protocol 233 sends a fourth message to the server via the message bus 22.

Therefore, according to different scenes, the required data acquisition protocol and uplink interface protocol can be freely selected, and the aims of light weight, flexibility and full coverage are achieved. And meanwhile, the possibility of foot remaining for the functional components is expanded.

In fig. 3, the first data acquisition component 31, the second data acquisition component 32, and the third data acquisition component 33 each include a sensor acquisition protocol adapted to acquire sensor data, a CNC acquisition protocol adapted to acquire CNC data, and a PLC acquisition protocol adapted to acquire PLC data.

When the user arranges the first data collection assembly 31 at the sensor data source 41, the sensor collection protocol in the first data collection assembly 31 is activated based on the user's setup operation on the human-machine interface, and sensor data is acquired from the sensor data source 41 by the activated sensor collection protocol.

When the user connects the second data acquisition component 32 with the CNC data source 42, the second data acquisition component 32 receives a handshake message from the CNC data source 42 containing an identification of the CNC data source 42. The second data acquisition component 32 parses the identity of the CNC data source 42 from the handshake message, selects and activates a CNC acquisition protocol based on the identity, and retrieves CNC data from the CNC data source 42 by the activated CNC acquisition protocol.

When the user connects the third data acquisition component 33 with the PLC data source 43, the third data acquisition component 33 receives a handshake message from the PLC data source 43 containing an identification of the PLC data source 43. The third data acquisition component 33 parses the identity of the PLC data source 43 from the handshake message, selects and activates a PLC acquisition protocol based on the identity, and acquires PLC data from the PLC data source 43 by the activated PLC acquisition protocol.

The first data acquisition component 31 packages the acquired PLC data set into a first message, the second data acquisition component 32 packages the acquired CNC data set into a second message, and the third data acquisition component 33 packages the acquired PLC data set into a third message, wherein the message formats of the first message, the second message, and the third message are matched with the transmission protocol of the message bus 22. Also, the IoT gateway 34 that includes the MQTT interface 35 receives the first, second, and third messages via the message bus 22. The IoT gateway 34 may also have additional functionality such as data caching, wire-break retransmission, or load balancing. The MQTT interface 35 sends the first, second and third messages to the cloud 36.

In fig. 3, the IoT gateway 34 is combined with a plurality of data acquisition components, and the IoT gateway 34 may provide a data uplink interface and a data acquisition service, and each data acquisition component may be capable of realizing local data acquisition with low cost and limited performance, and transmitting the acquired data to the IoT gateway 34 through a distributed message bus, and forwarding to the cloud. The system shown in fig. 3 has significant advantages in a scene where the targets to be mined are dispersed and diverse.

From the perspective of deployment platform analysis, the embodiment of the invention can be deployed on various software and hardware platforms, such as: the micro embedded platform, the Internet of things gateway, the industrial control computer, the server, the virtualized container platform and the like can flexibly select the targets of the operation platform according to different requirements (i.e. the targets are not limited by the platform). The modular system architecture and the platform-independent feature of the embodiments of the present invention not only can be deployed to a single platform, but also can be deployed in a distributed manner to multiple (or multiple) physical platforms to maximize performance and cost benefits. Such as: when the quantity of the data to be collected is large, a single platform with stronger transport capacity can be selected to implement the embodiment of the invention; when the amount of the data to be acquired is small, the embodiment of the invention can be implemented by selecting a platform with relatively common performance; when the data to be adopted are scattered and the data quantity is large, the embodiment of the invention can be implemented by adopting a scheme of combining a plurality of pieces; when the data to be acquired are scattered and the quantity is small or very small, the corresponding platform distribution deployment can be selected according to the situation to implement the embodiment of the invention. Therefore, the implementation mode of the invention can be flexibly matched and selected according to the requirement, thereby improving the operation efficiency, saving the cost, reducing the deployment difficulty and improving the performance.
