Problems solved by technology

[0002] Generally, in the same device, there may be multiple services running at the same time. Due to the reasons of development sequence or for the convenience of management, different APPs may complete different business functions; it is possible that these functions are related to the IOT platform. Related, it is necessary to establish and maintain a connection with the IOT platform; the usual practice is that each APP maintains its own connection with the IOT platform; this is the most convenient, but at the same time there will be redundancy and wasted things, one is that multiple APPs have Multiple connections, maintaining the heartbeat of the connection may cause traffic loss; (in an actual application scenario, assuming MQTTS is used, the heartbeat is 60s once, and the monthly traffic consumption is about 10MB); the other is that different apps may have basically the same Repeated processes for connections are also a waste of system resources

Embodiment 1

[0034] refer to figure 1 As shown, an Internet of Things center 1 (Device IOT Hub), which is carried on a gateway 4 device 3;

[0035] Described Internet of Things center 1 comprises following module:

[0036] The connector 11 is used to communicate with the Internet of Things platform 2 (IOT Platform) of the peripheral device, and maintain a keep-alive connection with the IoT platform 2, and maintain a keep-alive connection by sending a heartbeat packet to the Internet of Things platform 2 on a regular basis;

[0037] In addition, the connector 11 is also used for reconnection when the connection with the IoT platform 2 is disconnected.

[0038] The message subscribing and sending module 12 is used for subscribing the message sent by the IoT platform 2 through the connector 11 and sending it to the APP, and sending the data reported by the APP to the corresponding IoT platform 2 through the connector 11.

[0039] The message subscription and sending module 12 contains a mes...

Embodiment 2

[0042] see figure 2 , an Internet of Things system, comprising an Internet of Things platform 2 (IOT Platform, preferably a cloud platform), a gateway 4, and a device 3; the gateway 4 has a built-in Internet of Things center 1 (Device IOT Hub) as described in Embodiment 1;

[0043] The gateway 4 is equipped with APPs, and these APPs include gateway APPs managed by the gateway 4 itself, and also include device APPs for managing the devices 3 or sensors attached to the gateway 4 .

[0044] The message subscription and sending module 12 sends messages to the APP and collects messages from the APP; the connector 11 communicates with the IoT platform 2 and maintains a keep-alive connection.

Embodiment 3

[0046] A communication method for the Internet of Things, said method is implemented by relying on the above-mentioned Internet of Things system;

[0047] The Internet of Things platform 2 is connected to the device 3 and the gateway 4 through the Internet of Things center 1;

[0048] The Internet of Things platform 2 and the Internet of Things center 1 perform a keep-alive connection;

[0049]When the message of the Internet of Things platform 2 is to be sent to the corresponding APP such as the device APP or gateway APP, the Internet of Things platform 2 sends the message to the connector 11 of the corresponding Internet of Things center 1, and sends the message to the message through the connector 11. The subscription and sending module 12 is sent to the corresponding device APP or gateway APP by the message subscription and sending module 12;

[0050] When the device APP or the gateway APP wants to send a message to the IoT platform 2, the device APP or the gateway APP se...

Abstract

The invention discloses an Internet-of-Things center, and the center comprises the following modules: a connector which is used for communicating with an external Internet of Things platform and maintaining the keep-alive connection with the Internet of Things platform; and a message subscribing and sending module which is used for subscribing a message issued by the Internet-of-Things platform through the connector, sending the message to the APP and sending data reported by the APP to the corresponding Internet-of-Things platform through the connector. The center undertakes the task of keep-alive connection with the Internet-of-Things platform, and keep-alive connection between the APP and the Internet-of-Things platform is not needed, so that the flow is saved, and the APP is concentrated in services. Meanwhile, different APPs on the same hardware device or gateway do not need to repeatedly carry out the registration process, and only need to establish the connection with the Internet-of-Things center on the premise that the device or gateway establishes the connection with the Internet-of-Things platform. Meanwhile, the invention also provides an Internet-of-Things system and an Internet-of-Things communication method.
