For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components; wireless connections or wired connections. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0024] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] The embodiment of the present invention discloses an Internet of Things device communication system, such as Figure 1 As shown, the system includes:

[0026] Multiple IoT devices 101. Exemplarily, the multiple IoT devices may be any number of IoT devices. In the embodiment of the present application, the multiple IoT devices may be all IoT devices in any campus or building.

[0027] At least one IoT controller 102, each of which is connected to a corresponding IoT device and is used to obtain the operating status information of the corresponding IoT device. For example, in an embodiment of the present application, the IoT controller is an IoT controller with MQTT routing, MQTT forwarding, and role management functions. MQTT routing is used to parse and translate received data information, MQTT forwarding is used to forward the data parsed and translated by MQTT routing to the IoT device or IoT cloud platform, and the role management function is used to manage the information connected to the IoT device; the operating status information is information that can reflect the working status of the IoT device, for example, the operating status information of the IoT device air conditioner can be the working temperature of the air conditioner, and the operating status information of the IoT device lighting can be the switch and brightness of the lighting; the IoT controller can receive the operating status information actively reported by each IoT device, and can also actively obtain the operating status information of each IoT device. Figure 1 In the example, one IoT controller is included. Those skilled in the art may also configure multiple IoT controllers according to actual needs.

[0028] The IoT cloud platform 103 is connected to each IoT controller and is used to obtain the operating status information of the IoT devices from the IoT controller and send control information to the corresponding IoT devices through the IoT controller. For example, in an embodiment of the present application, the IoT cloud platform can manage IoT devices. The IoT cloud platform will send control information for each IoT device to the IoT controller, and the IoT controller will send the control information to the corresponding IoT device. At the same time, the IoT cloud platform will also receive the operating status information reported by each IoT device through the IoT controller.

[0029] The IoT device communication system provided by the present invention connects multiple IoT devices to at least one IoT controller, and the IoT controller is connected to the IoT cloud platform. The IoT controller can realize the forwarding of communication messages between multiple IoT devices and the IoT cloud platform, thereby reducing the communication pressure of the cloud proxy server, and can better realize the communication between the IoT devices and the IoT cloud platform, solving the problem in the prior art that a large number of IoT devices establish TCP long connections with the cloud proxy server for communication, which may cause network export instability.

[0030] As an optional embodiment of the present invention, the system further includes:

[0031] The local proxy server is connected to the IoT device and the IoT controller respectively, and is used to forward the communication information between the IoT device and the IoT controller. For example, in an embodiment of the present application, the local proxy server can also be called an MQTT local Broker, and multiple IoT devices and IoT controllers will register with the MQTT local Broker and publish or subscribe to topics on the MQTT local Broker. For example, there are three IoT devices, floor10_room1_light, floor2_room2_aircondition, and basement_waterlevel, and two IoT controllers, MQTT IoT controller 1 and MQTT IoT controller 2. Then, these three IoT devices will subscribe to topics related to control information and publish topics related to status information; the two controllers will subscribe to topics related to status information and publish topics related to control information.

[0032] The cloud proxy server is connected to the IoT controller and the IoT cloud platform, respectively, and is used to forward communication information between the IoT controller and the IoT cloud platform. For example, in an embodiment of the present application, the cloud proxy server can also be referred to as an MQTT cloud broker. The IoT controller and the IoT cloud platform will register with the MQTT cloud broker and establish a topic connection with the MQTT cloud broker. For example, if there are two IoT controllers, MQTT IoT controller 1 and MQTT IoT controller 2, and an IoT cloud platform, all three entities will establish a topic connection on the MQTT cloud broker. At the same time, a topic mapping algorithm can be configured in the IoT controller to convert topics from the cloud proxy server to topics from the local proxy server. For example, the cloud-based topic building1_floor10_room1_light_cmd can be mapped to the local topic floor10_room1_light_cmd. The MQTT IoT controller can perform MQTT forwarding based on the mapping relationship between the local proxy server's MQTT connection and the cloud proxy server's MQTT connection corresponding to the topic. MQTT forwarding only needs to be performed on the primary MQTT IoT controller.

[0033] As an optional embodiment of the present invention, the system includes multiple Internet of Things controllers, and the multiple Internet of Things controllers are communicatively connected with each other.

[0034] For example, when there are multiple IoT controllers, each controller is connected to other controllers for communication. Each controller will record various IoT information in real time and synchronize the IoT information to other IoT controllers to achieve mutual backup of IoT information between multiple IoT controllers. In an embodiment of the present application, IoT controllers are distributed in different buildings. A building can contain multiple IoT devices and multiple IoT controllers. The IoT information between IoT controllers in the same building is backed up to each other, and each IoT controller in the same building can be connected to all IoT devices in the building. Each IoT controller can obtain all IoT information in the building, or it can only subscribe to the information of interest, and then obtain the full amount of IoT information through message backup between IoT controllers. Different IoT controllers may be responsible for managing different IoT devices. For example, IoT controller 1 is responsible for managing all IoT devices on floors 1-5 of building A; IoT controller 2 is responsible for managing all IoT devices on floors 6-10 of building A. When it is necessary to achieve centralized communication of large-scale IoT networks in buildings or campuses, different IoT controllers can be used to manage different IoT devices. This can achieve complex MQTT routing while controlling the risk of MQTT transmission reliability within the building or campus IoT. There is no need to worry about individual IoT devices and IoT controllers failing to manage a large number of IoT device clusters due to MQTT communication failures caused by poor 4G or 5G signals, thus reducing the complexity of IoT system deployment.

[0035] In an embodiment of the present invention, each IoT controller can also communicate with all IoT devices to obtain the operating status information of each IoT device and the corresponding IoT control instructions. The IoT controller will then judge the obtained information and forward the information corresponding to the IoT device it is responsible for managing based on the judgment results.

[0036] The embodiment of the present invention also discloses an Internet of Things device communication method, which is applied to the Internet of Things controller in the Internet of Things device communication system of the above embodiment, such as Figure 2 As shown, the method includes the following steps:

[0037] Step 201 responds to the acquisition of operating status information from the IoT device and the receipt of control instructions from the IoT cloud platform. For example, the IoT controller receives control instructions for each IoT device from the IoT cloud platform. In this embodiment of the present application, any IoT controller can obtain control instructions for all IoT devices or only for the IoT devices it is responsible for managing.

[0038] In step 202, upon receiving a control instruction from the IoT cloud platform, the control instruction is sent to the corresponding IoT device based on the IoT device identifier contained in the control instruction. For example, when any IoT controller receives a control instruction from an IoT device, it sends the control instruction to the corresponding IoT device based on the IoT device identifier corresponding to the control instruction. The IoT device can then adjust its operating state based on the received control instruction.

[0039] In step 203, upon obtaining the operating status information of the IoT device, the operating status information is sent to the IoT cloud platform. For example, the IoT controller can obtain the operating status information of the connected IoT device and forward the operating status information to the IoT cloud platform, allowing the IoT cloud platform to monitor the operating status of the IoT device.

[0040] The IoT device communication method provided by the present invention forwards the communication information between the IoT device and the IoT cloud platform through the IoT controller, thereby reducing the communication pressure of the cloud proxy server, and can better realize the communication between the IoT device and the IoT cloud platform. It solves the problem in the prior art that a large number of IoT devices establish TCP long connections with the cloud proxy server for communication, which may cause network export instability, reduces the complexity of IoT management in buildings and parks, and does not require modification of the original IoT communication code, providing strong technical guarantee for the rapid development of business.

[0041] As an optional embodiment of the present invention, step 202 includes:

[0042] When any IoT controller receives the control instruction, it determines whether the corresponding IoT device is the IoT device that the IoT controller is responsible for managing based on the IoT device identifier contained in the control instruction. For example, in an embodiment of the present application, any IoT controller can obtain control instructions for all IoT devices, and determine whether the IoT device is the IoT device that the IoT controller is responsible for managing based on the IoT device identifier contained in the control instruction. The role management function module of the IoT controller is pre-set with the identifier of the IoT device that needs to be managed. When the IoT controller receives a control instruction, it can compare the IoT device identifier contained in the control instruction with the IoT device identifier in the role management function module to determine whether the IoT device corresponding to the control instruction is the IoT device that the IoT controller is responsible for managing.

[0043] When the IoT device corresponding to the IoT device identifier is an IoT device managed by the IoT controller, the control instruction is sent to the corresponding IoT device. For example, in an embodiment of the present application, if the IoT controller determines based on the judgment result that the IoT device corresponding to the control instruction is an IoT device managed by the IoT controller, the control instruction is forwarded; if not, the control instruction is not forwarded.

[0044] As an optional embodiment of the present invention, step 203 includes:

[0045] When any IoT controller obtains the operating status information of the IoT device, it determines whether the IoT device corresponding to the operating status information is the IoT device that the IoT controller is responsible for managing. For example, in an embodiment of the present application, any IoT controller can obtain the operating status information of all IoT devices and determine whether the IoT device corresponding to the operating status information is the IoT device that the IoT controller is responsible for managing. The role management function module of the IoT controller pre-sets the identifier of the IoT device that needs to be managed. When the operating status information of the IoT device is obtained, the identifier of the IoT device can be compared with the IoT device identifier pre-set in the role management function module to determine whether the IoT device corresponding to the operating status information is the IoT device that the IoT controller is responsible for managing.

[0046] If the IoT device corresponding to the operating status information is an IoT device managed by the IoT controller, the control instruction is sent to the corresponding IoT cloud platform. For example, in an embodiment of the present application, if the IoT controller determines based on the judgment result that the IoT device corresponding to the operating status information is an IoT device managed by the IoT controller, the operating status information is forwarded; if not, the operating status information is not forwarded.

[0047] The embodiment of the present invention also discloses an Internet of Things device communication device, which is applied to an Internet of Things controller in the Internet of Things device communication system of the above embodiment, such as Figure 3 As shown, the device includes:

[0048] The response module 301 is used to respond to the operation of obtaining the operating status information of the IoT device side and the operation of receiving the control instructions issued by the IoT cloud platform side;

[0050] The second sending module 303 is configured to send the operating status information of the IoT device to the IoT cloud platform upon obtaining the operating status information.

[0051] The IoT device communication device provided by the present invention forwards the communication information between the IoT device and the IoT cloud platform through the IoT controller, thereby reducing the communication pressure of the cloud proxy server, and can better realize the communication between the IoT device and the IoT cloud platform. It solves the problem in the prior art that a large number of IoT devices establish TCP long connections with the cloud proxy server for communication, which may cause network export instability, reduces the complexity of IoT management in buildings and parks, and does not require modification of the original IoT communication code, providing strong technical guarantee for the rapid development of business.
