Description

Internet of things system and connection method

The present invention relates to a system and a connection method thereof, and particularly to an Internet of Things system and a connection method thereof.

The current IoT device establishes a connection with a client when executing the AP mode, and obtains a service set identifier (SSID, Service Set Identifier) of a central control unit. When the IoT device obtains the When the service sets the identification code, the IoT device disconnects the connection with the client and switches to execute the client mode, and requests a connection to the central control terminal according to the service setting identifier so that The IoT device establishes a connection with the central control terminal, and uses the method described above to complete the connection setting of multiple IoT devices and the central control terminal, so that the central control terminal can directly monitor the status of the multiple IoT devices. However, since the current method of controlling an IoT device is switched from the access point mode to the client mode, it cannot switch back to the access point mode to inform the client about the IoT device and the central control. The connection status of the remote end, the client often cannot know whether the IoT device and the central control end have indeed established a connection.

Furthermore, because the current IoT device cannot be connected to the client and the control terminal at the same time, the IoT device must constantly switch between the access point mode and the client mode. In order to receive the data of the user terminal and the central control terminal at any time, the IoT device has certain inconvenience in operation.

Therefore, it is a first object of the present invention to provide an Internet of Things system connection method in which the Internet of Things device and the central control terminal and the user terminal can be continuously connected at the same time without interruption.

The method for connecting the Internet of Things system includes a step A, a step B, and a step C, and a step D.

Step A: One of the IoT devices sets a channel of itself according to a cloud channel of the central control terminal to be the same as the cloud channel of the central control terminal.

Step B: The client sets a channel of itself according to the channel of the one of the IoT devices to be the same as the channel of the one of the IoT devices.

Step C: One of the Internet of Things devices establishes a connection with the client according to an authentication data.

Step D: The client controls one of the IoT devices to establish a connection with the central control terminal.
