Description

A method for binding IoT devices and object models based on network communication

technical field

The invention relates to a method for binding an Internet of Things device and an object model based on network communication, and belongs to the technical field of Internet of Things device management.

Background technique

Since the concept of Internet of Things (IOT) was proposed in 1999, after more than 20 years of development, it finally moved from the laboratory to the real life. The Internet of Things is an extension and expansion of the Internet. The difference is that the terminals of the Internet are PCs and servers, while the terminals of the Internet of Things can be in various forms, such as wearable devices, environmental monitoring devices, virtual display devices, and so on. That is to say, the goal of the Internet of Things is to connect all things to the network and realize the communication between objects and objects and between objects and people.

The terminals of the Internet of Things can be in various forms, so the number of terminals in the Internet of Things era must not only be limited to one per person in the Internet era, but also more devices to be connected to the Internet exist in industrial production and daily life. According to the forecast of a major mobile phone manufacturer, the number of IoT devices is expected to reach more than 100 billion levels by 2025. At present, a variety of new terminal forms have appeared on the market, which also indicates that the terminal form of the Internet of Things is no longer limited to the card form. The prosperity of markets such as smart wearables, smart communities, and the Internet of Vehicles also indicates that the application scenarios of the Internet of Things are becoming more and more abundant. The networking methods of the Internet of Things are also increasingly rich, and are no longer limited to NFC and RFID card swiping scenarios.

In the early stage of the development of the Internet of Things, people focused more on the development and enrichment of terminals, but the Internet of Things is not only about equipment, but also the management of equipment, but the current status of the Internet of Things is to connect for the sake of connection, which cannot improve production efficiency. The phenomenon is caused by the lack of cloud management, and at the same time, it cannot solve the "3L" problem raised by Google Glasses. "3L" means long time, long distance and low price. The Internet of Things is regarded as a comprehensive grid, and cloud management should be developed to form an ecological closed loop.

SUMMARY OF THE INVENTION

Aiming at the deficiencies of the prior art, the present invention provides a method for binding an Internet of Things device and an object model based on network communication. The Internet of Things device is mapped to an object model and stored in a database at the server side. Management of networked devices. Before this operation, it is necessary to bind the IoT device and the object model to realize a one-to-one correspondence between the IoT device and the object model, which is also the core of the present invention. To achieve binding through network communication, the user needs to provide the binding code of the device (BindCode, which needs to be unique among all IoT devices) on the device side, send the binding code to the server to request binding, and the server completes the binding operation , and store the correspondence between IoT devices and object models in the database. During the binding process, the user only needs to provide the BindCode to ensure the fast and convenient completion of the binding.

Terminology Explanation:

Object model: refers to the mapping of IoT devices into a data model that exists in a database, that is, a virtual device stored in the database.

bind: Binding refers to the process of establishing a one-to-one relationship between a real IoT device and the object model stored in the database, that is, establishing a one-to-one correspondence between deviceId and BindCode.

deviceId: is a string that can identify the device and is globally unique, and each deviceId represents an IoT device.

BindCode: The binding code is a string of strings that the physical IoT device needs to provide to the background when performing the bind operation. It is required to be unique among all the devices of the user and is customized by the user.

The technical scheme of the present invention is as follows:

A method for binding an IoT device and an object model based on network communication, comprising the following steps:

(1) After the IoT device is turned on, determine whether the IoT device has been bound with the server-side object model, if not, go to step (2), and if it has been bound, go to step (5);

(2) The IoT device sends a device binding request to the server through network communication, and the message contains a globally unique BindCode message;

(3) After receiving the device binding request, the server generates a globally unique deviceId for the IoT device according to the specific information of the IoT device.

(4) After the server stores the one-to-one correspondence between the IoT device and the object model in the database, the one-to-one correspondence between the IoT device and the object model refers to the connection between the IoT device and the object model through the globally unique deviceId. , send the deviceId generated in step (3) to the IoT device through network communication, and the IoT device saves the BindCode and deviceId locally.

(5) After the IoT device binding is completed, the data of the IoT device is synchronized to the server-side object model, and the server manages the IoT device through the management of the object model, including memory data management, device binding management, Data persistence and data synchronization management.

Preferably, in step (1), the judgment method is to read the binding information bind.xml stored locally. If the reading is successful and the deviceId in the file is not empty, it proves that the device has been bound and does not need to be bound again. If the reading fails or the deviceId is empty, a binding operation is required.

Preferably, in step (3), deviceId contains the relevant information of the device, and the composition format is: the company ID_device type_timestamp, the company ID represents which company the device belongs to; the device type indicates the current device type, such as wearing devices, monitoring devices, etc.; the timestamp is when the device requested the binding.

The above-mentioned system of binding IoT devices and IoT models based on network communication includes IoT devices and server-side IoT devices. IoT devices refer to IoT devices with Internet connection, such as wearable devices, environmental monitoring devices, and virtual display devices. etc., the IoT device and the server-side thing model communicate through the network.

The beneficial effects of the present invention are:

1. The format of the deviceId generated by the present invention is: company identification_device type_timestamp, through deviceId, information such as the company, device type and binding time of the device can be easily learned.

2. The deviceId of the device in the present invention is generated by the server according to specific rules, which not only can quickly understand the device information, but also has high security. Since the deviceId is generated by the server, it is not easy to be cracked by a third party, thus effectively avoiding the leakage of device-related data.

3. The present invention establishes a one-to-one relationship between the IoT device and the server-side object model, thereby ensuring that the management of the IoT model will be synchronized to the IoT device, and the changes of the IoT device will be synchronized to the IoT device. Model, which is convenient for users to remotely manage IoT devices.

4. The method for binding the IoT device and the object model provided by the present invention has better versatility. In the invention, the binding code can be specified by the user, and it is not mandatory to use a specific binding code, so that the user has higher selectivity and can be adapted to more IoT devices.

5. The present invention will save the binding state of the device. When the user is binding, the device side will determine whether the current IoT device has been bound, which can effectively reduce unnecessary time-consuming networking operations and improve application efficiency.
