The present invention is to provide a control system including a sensing device capable of periodically driving a corresponding operation device based on a trigger policy, wherein the sensing device and the operation device have the same trigger policy stored therein. The control system is characterized in that the trigger policy at least includes a trigger code, a time data (such as 'after 15 minutes') and an operation data (such as 'turn on a lamp'). When the sensing device detects a sensing signal, the sensing device generates and transmits a trigger instruction to the operation device. When the operation device determines that a trigger code carried in the trigger instruction matches with a second identification code stored therein, the operation device calculates an expiration time of the time data based on the current time, and then executes an action corresponding to the operation data at the expiration time.

The present invention is to provide a network synchronization system, wherein a first network apparatus is connected to a physical line, stores a first profile at least including a Service Set Identifier (SSID), a pre-shared key and a channel, and can connect to the Internet according to the first profile and send out a detection message, and at least one second network apparatus is also connected to the physical line and can automatically generate a request message according to the detection message. When receiving the request message, the first network apparatus sends out the first profile in reply. Based on the first profile, the second network apparatus adds a second profile including the same SSID and pre-shared key but a different channel to itself, and then makes a seamless connection with the Internet through the physical line and the first network apparatus according to the second profile.
