Problems solved by technology

[0014] The purpose of the present invention is: in order to solve the difficulty in satisfying the heterogeneous incompatibility of equipment when implementing equipment interoperability in the Internet of Things system under the prior art, and the existing equipment interoperability mostly starts from the top-level standard or the vertical field, and it is difficult to achieve horizontal equipment interoperability. For the problem of operation, the present invention provides an interoperability scheduling method for Internet of Things devices, and proposes a unified resource representation structure for Internet of Things devices to convert physical devices into logically corresponding virtual device resources, based on the formed virtual device resources , proposed two interactive modes of interoperable scheduling between resources, the passive interoperable scheduling is realized by creating a subscription to the specified resource and receiving the notification, the active operation scheduling is realized by sending a request to the specified resource and getting a response, and the resource-level operation is used to realize Device Interoperability

Embodiment approach

[0076] As a preferred implementation manner, the basic resource operations may also include:

[0077] Resource update Update: used to update the attribute information of the resource;

[0078] Resource deletion Delete: Used to delete resources.

[0079] As a preferred implementation manner, the interaction scheduling between resources includes resource interaction based on subscription notification and resource interaction based on request response, and the resource interaction based on subscription notification implements subscription operation on resources by using subscription.

[0080] The resource interaction based on subscription notification is essentially a passive resource scheduling, which provides a mechanism for resource change monitoring and notification. One of the devices as a subscriber can subscribe to a certain (or some) device resources based on dependent data information, etc., the subscriber can tell the subscriber a notification address (URL), and tell t...

Embodiment 1

[0102] Such as Figure 6 The following describes the registration process of smart furniture device resources:

[0103] 1. The device deployed in the environment sends a resource creation request to the smart home resource management system;

[0104] 2. After the system receives the creation request, it first judges whether the requesting device has the resource creation permission, and if it does not have the creation permission, it returns the creation failure to the device;

[0105] 3. Otherwise, continue to judge whether the resource type specified in the resource request can be supported, and if the resource type is not supported, return creation failure;

[0106] 4. Otherwise, execute the operation of creating a new resource, and assign a value to the corresponding type of read-only attribute according to the resource modeling method. If there is an error in the creation process, return resource creation failure;

[0107] 5. Otherwise, after the resource creation oper...

Embodiment 2

[0111] Such as Figure 7 Request-response-based device interoperability between the access control switch and the RFID reader shown:

[0112] Between the devices that need active interoperability scheduling, according to the data information to be requested, resource requests are sent to the corresponding target resources, and responses are obtained, so as to obtain the required information. For example, after successfully registering through the device resource, there are access control switch resources and RFID card reader resources in the system, and the access control switch resource can obtain the RFID code of the RFID card reader resource by sending a resource request, and then execute the corresponding Switch operation, so as to realize the interoperability scheduling of access control switch and RFID card reader.

[0113] 1. The access control switch resource sends a resource retrieval retrieve request to the RFID card reader resource, which specifies the RFID code at...

Abstract

The invention discloses an Internet of Things (IoT) equipment interoperation scheduling method, and relates to the field of the IoT based on virtual resources, for solving the problems that in the prior art, the IoT system is difficult to achieve interoperation of equipment and the equipment is heterogeneous and incompatible, and interoperation of the existing equipment starts from a top-layer standard or a vertical field and thus the horizontal equipment is difficult to achieve interoperation in a targeted manner. The invention provides a unified resource expression structure for the IoT equipment to convert the physical equipment into a logically corresponding virtual equipment resource; based on the formed virtual equipment resource, an interoperation scheduling interaction mode betweentwo resources is provided, passive operation scheduling is achieved through building subscription for the assigned resource and receiving a notice, active operation scheduling is achieved through sending the request to the assigned resource and acquiring a acknowledgement, and the interoperation of the equipment is achieved with the aid of operation of the resource level.

Description

technical field [0001] The invention relates to the field of the Internet of Things based on virtual resources, in particular to a method for scheduling interoperation of Internet of Things devices. Background technique [0002] The Internet of Things (IoT) is an ubiquitous network of physical objects, virtual objects, and sensing, computing, and communication capabilities. The initial vision of the Internet of Things is to establish a hyperlinked global ecosystem, through the deployment of physical devices, communication networks, etc., to achieve interactive communication between "things" and "things", so as to build an ecosystem of connected things. To provide people with a more convenient and intelligent production and living environment. Among them, in order to realize the communication between "things" and "things", the key part is to realize the interoperability scheduling between IoT devices, and provide interoperability solutions between devices that need to be int...
