Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) technology, and in particular to a method and apparatus for interaction between a device simulator and an IoT platform. Background Technology

[0002] Every smart product project requires a complete process: requirements confirmation -> product definition -> profile generation -> platform product data generation -> hardware completion of electronic control development -> device access to the platform according to the protocol -> functional and stability testing -> completion of access. However, in the process from the developers completing hardware electronic control development to the device undergoing functional testing, the device simulator can first generate device data based on the product definition, simulating a perfect device. This allows developers to develop and improve functions, enabling real devices to access the platform more quickly and shortening the launch cycle of new devices.

[0003] Existing device simulators simulate vendors' IoT devices via edge-to-cloud and cloud-to-cloud interfaces. The simulator processes device data, converting it into corresponding device messages using edge-to-cloud and cloud-to-cloud protocols. The cloud then reads and responds to these messages. However, existing device simulators cannot connect to third-party vendors' IoT devices by configuring product information in the cloud. First, the third-party vendor needs to be integrated into the device simulator, and relevant cloud products need to be added to the cloud product library. Only after adaptation development and testing between the device simulator and the cloud can the corresponding IoT device be simulated, which impacts the flexibility and practicality of IoT device testing.

[0048] First, let's explain the following technical terms:

[0049] IOT is short for Internet of Things.

[0050] Device simulator: An application used to simulate data from IoT devices.

[0051] The present disclosure is described below with reference to the accompanying drawings.

[0052] This disclosure provides an exemplary embodiment of a method for interaction between a device simulator and an Internet of Things (IoT) platform. This method can be used in a device simulator. Figure 1 A flowchart illustrating a method for interaction between a device simulator and an Internet of Things (IoT) platform according to an exemplary embodiment of this disclosure is shown, such as... Figure 1 As shown, the method includes the following steps:

[0053] Step S101: The device simulator obtains the product information of the target product configured on the IoT platform;

[0054] Step S102: The device simulator acquires the device information of the target device to be simulated;

[0055] Step S103: The device simulator generates the device parameters of the target device based on the product information of the target product and the device information of the target device;

[0056] In step S104, the device simulator sends a device message to the message gateway, wherein the device message carries the device parameters of the target device, and the message gateway is used to forward the device message to the corresponding device management module in the IoT platform for message processing according to the type of the device message.

[0057] Step S105: The device simulator receives the message processing result returned by the IoT platform.

[0058] In this embodiment, developers can configure new product information on a cloud-based IoT platform. The target product can be any of the new products, and its information may include, but is not limited to, product ID, product name, product service items, and product attribute items. Users can select the target product automatically synchronized from the IoT platform in the device simulator and set the device information of the target device for that product. The target device can be any device of the target product. The device information of the target device may include, but is not limited to, device name and device ID. The device simulator can generate default device parameters for the target device based on the product information of the target product and the device information of the target device.

[0059] In some embodiments, the device parameters of the target device can be displayed on the device simulator's interface. The device simulator simulates the target device sending device messages to the IoT platform, wherein the device messages carry the device parameters of the target device. The device messages first arrive at the message gateway, which forwards the device messages to the corresponding device management module in the IoT platform for message processing based on the message type. After processing the device messages, the device management module returns the processing result to the device simulator. The types of device messages include: device registration messages and device control messages; the corresponding device management module in the IoT platform may include: a device registration center and a device control center.

[0060] In some embodiments, when the device message type is a device registration message, the message gateway is used to forward the device message to the device registration center in the IoT platform for message processing, wherein the device registration center processes the device message by:

[0061] Determine whether the target device is a new device;

[0062] If the target device is determined not to be a new device, an error message is output.

[0063] If the target device is determined to be a new device, then the target device is added to the database; a key for the target device is generated based on the device parameters of the target device and the product information of the target product; the target device is activated and brought online.

[0064] In some embodiments, when the device message is a device control message, the message gateway forwards the device message to the device control center in the IoT platform for message processing. The device control center processes the device message by:

[0065] The device control commands and the device status of the target device are detected from the device messages;

[0066] The device status of the target device is changed according to the device control command;

[0067] Store the modified device state of the target device.

[0068] In some embodiments, after the corresponding device management module in the IoT platform processes the device message, it further includes:

[0069] The results of the message processing are synchronized to the business management center in the IoT platform for storage. The business management center is used to synchronize the results of the message processing to the device simulator and the third-party control platform. The third-party control platform is bound to the target device, and uses this binding relationship to control the target device and display its device parameters and status.

[0070] This exemplary embodiment provides another method for interaction between a device simulator and an Internet of Things (IoT) platform. This method can be used with an IoT platform. Figure 2 A flowchart illustrating a method for interaction between a device simulator and an Internet of Things (IoT) platform according to another exemplary embodiment of this disclosure is shown, such as... Figure 2 As shown, the method includes the following steps:

[0071] Step S201: The IoT platform sends the configured product information of the target product to the device simulator, wherein the device simulator is used to generate the device parameters of the target device based on the product information of the target product and the device information of the target device.

[0072] Step S202: The IoT platform receives a device message sent by the device simulator forwarded by the message gateway, wherein the device message carries the device parameters of the target device;

[0073] Step S203: The IoT platform forwards the device message to the corresponding device management module for message processing according to the type of the device message;

[0074] In step S204, the IoT platform sends the result of the message processing to the device simulator.

[0075] In some embodiments, the device message type includes a device registration message. The IoT platform forwards the device message to a device registration center for message processing. The device management module includes the device registration center, wherein the device registration center processes the device message by:

[0076] Determine whether the target device is a new device;

[0077] If the target device is determined not to be a new device, an error message is output.

[0078] If the target device is determined to be a new device, then the target device is added to the database; a key for the target device is generated based on the device parameters of the target device and the product information of the target product; the target device is activated and brought online.

[0079] In some embodiments, the device message type includes a device control message. The IoT platform forwards the device message to a device control center for message processing. The device management module includes the device control center, wherein the device control center processes the device message by:

[0080] The device control commands and the device status of the target device are detected from the device messages;

[0081] The device status of the target device is changed according to the device control command;

[0082] Store the modified device state of the target device.

[0083] In some embodiments, after the IoT platform forwards the device message to the corresponding device management module for message processing according to the type of the device message, it further includes:

[0084] The IoT platform synchronizes the message processing results to the business management center within the IoT platform for storage. The business management center is used to synchronize the message processing results to the device simulator and a third-party control platform. The third-party control platform is bound to the target device, and uses this binding relationship to control the target device and display its device parameters and status.

[0085] The device simulator and IoT platform interaction method provided in the above-disclosed embodiments synchronizes the product information of the target product configured on the IoT platform with the device simulator, and generates device parameters of the target device based on the product information of the target product and the device information of the target device set by the user. This simulates the target device sending device messages to the message gateway. The message gateway forwards the device messages to the corresponding device management module in the IoT platform. The device management module processes the device messages and then returns the processing results to the device simulator. This solves the problem in related technologies where the device simulator cannot access third-party manufacturers' IoT devices by configuring product information in the cloud, which affects the flexibility and practicality of IoT device testing. It improves the flexibility and practicality of IoT device testing, reduces the manpower cost for developers to redevelop the simulator, and realizes the need for one-click configuration and immediate simulation.

[0086] The embodiments of this application will be described and illustrated below through preferred embodiments.

[0088] 1) A basic overview of the entire project built using the Spring Boot framework;

[0089] 2) The communication method between the device simulator and the cloud-based IoT platform is constructed using MQTT message components, NAT's message components, and the HTTP protocol;

[0095] (2) A solution suitable for rapid access, testing and linkage of equipment.

[0096] Figure 3 A schematic diagram of the architecture of an Internet of Things (IoT) platform according to a preferred embodiment of the present disclosure is shown, such as... Figure 3 As shown, the IoT platform in this preferred embodiment mainly includes the following components:

[0101] In addition, it may include: authentication, system monitoring services, monitoring management, security firewalls, etc.

[0102] Figure 4 A schematic diagram illustrating the interaction flow between an IoT device and an IoT platform according to a preferred embodiment of this disclosure is shown, such as... Figure 4 As shown, the device simulator can simulate virtual devices based on device data from the device itself, and then send device messages to the cloud-based internet platform. These device messages can include, but are not limited to, event reporting, device online / offline status, device registration, and device deletion. Device registration messages are authenticated and managed through the device gateway, and processed by the device registration center. Other device messages are forwarded through the message gateway, device control messages are processed by the device control center, and device log messages are processed by the persistent storage module. Data from the device registration center, device control center, and persistent storage module are synchronized to the device management module, rule engine management module, and log management module of the business management center, respectively. The system management module in the business management center can be used to manage data from third-party IoT platforms communicating through the cloud-to-cloud interface center. Users can control devices and link scenes through user-end apps and TVs, and can also view device data and device status synchronized by the business management center.

[0103] based on Figure 3 and Figure 4 The interaction process between the device simulator and the IoT platform in this preferred embodiment can be as follows: Figure 5 As shown, it specifically includes:

[0104] (1) Developers edit product information (attributes, services, agreements, categories, etc.) in the cloud.

[0105] (2) The device simulator software synchronizes product information in the cloud. When the developer creates a new product in the cloud, the device simulator updates the list of products that can be simulated.

[0106] (3) In device control, the device simulator sends device messages according to the protocol of the simulated product, allowing the device messages to enter the message gateway.

[0107] (4) In the device addition process, the user selects the product to be simulated by the device simulator. The device simulator generates the default device data and device status based on the product information.

[0108] (5) The message gateway verifies the data format and forwards the message to the corresponding module for processing based on the protocol parameters carried.

[0109] (6) The device registration message will be received by the device registration center. The device registration center will verify the device data in the message body and the corresponding product information in the cloud. After verification, it will determine whether it is a new device added. If it is not a new device, an error message will be returned to prompt the user; if it is a new device, the new device will be added to the database and a device key will be generated according to the product information and device name. The device will be activated and put online first, and then synchronized to the database and the device management module of the business management center.

[0110] (7) Device control messages will be received by the device control center. The device control center will check the device control instructions and device status in the message body, change the device status according to the instruction parameters, and synchronize the device status to the cache and message components, as well as the third-party console (APP, TV, etc.).

[0111] (8) The corresponding module of the business management center receives the device data and synchronizes it to the user's APP, TV or device simulator based on the device data.

[0112] (9) Equipment control or equipment addition is successful.

[0113] The following is an application example (simulating a smart product - a colored light bulb):

[0114] 1) Users configure new product information on the cloud IoT platform, select Huawei as the manufacturer, and edit product ID, product name, product service items, and product attribute items. Through these configurations, the device simulator can identify that the product belongs to Huawei and communicate with the device through the cloud-to-cloud connection link.

[0115] 2) The user selects the newly created colored light bulb product in the device simulator and sets a device name and a unique device ID.

[0116] 3) The device simulator automatically synchronizes product data from the cloud, generates default device data for the device based on the cloud product data and the device information entered by the user, and checks whether the device name is duplicated. The user can then view the device data, such as brightness, on / off status, color, and color temperature, in the device simulator interface.

[0117] 4) Users can click the QR code button to bind the virtual device using the accompanying APP.

[0118] 5) Once the binding is complete, the status of the virtual device will appear in the APP. When the user clicks the Connect Device button, the virtual device on the APP will go online. At this time, the user can choose to operate the device control on the APP or control the device through the space of the emulator terminal.

[0119] 6) The user changes the device switch attribute data of the device simulator terminal and sends the device data switch=1. After data conversion and cloud processing, the device simulator displays a rendered screen showing that the light bulb is on on the APP.

[0120] 7) The user operates the device simulator terminal to send the color temperature attribute data, and sends the device data colorTemperature=4000K. The APP receives the processed device data and will display the corresponding warm-toned light and color temperature value of 4000K.

[0121] 8) When the user disconnects the device, the APP displays that the device is offline, and the user cannot control the device through the APP.

[0122] 9) Once the user removes the device, they will see that the colored light device has been deleted from the APP.

[0123] 10) When the user closes the entire emulator terminal, the emulator will send a message that all emulator devices are offline and save the user's operation data to the local machine.

[0124] This disclosed embodiment is based on MQTT, NATS and HTTP network communication protocols to forward and process device data. By acquiring data from various configuration items in the cloud, the device simulator can simulate a perfect device. This can reduce the impact of network, hardware and driver issues on test results of real devices, and can also simulate devices for rapid development of device functions.

[0125] This disclosure enables IoT devices to quickly connect to the device simulator and cloud architecture by dynamically configuring parameters such as the category, service, protocol, attributes and instructions of IoT device products in the cloud. This improves the flexibility and practicality of IoT device testing, reduces the manpower cost for developers to redevelop the simulator, and realizes the need for one-click configuration and instant simulation.
