Description

Intelligent lamp system and its control method

The present invention relates to a smart lamp system, in particular to a smart lamp system involving the Internet of Things technology. The invention also relates to a control method of a smart lamp system.

In the past, smart lamps were controlled in a one-to-one manner such as unicast. At the same time, the data-source will only transmit the signal to a single fixture (as a data-sink). When the number of lamps to be controlled increases, the total signal transmission time will accumulate, causing the signal update frequency to be limited by the number of lamps (generally, the update frequency requirement is 25Hz).

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numbers.

Referring to FIG. 1, a first embodiment of the smart lamp 3 system 100 of the present invention includes a router 1, a control device 2 and a plurality of smart lamps 3.

The router 1 is a wireless router in this embodiment, and communicates with the control device 2 and the smart lamps 3 in a wireless manner.

The control device 2 includes a communication unit 21 and a control unit 22 electrically connected to the communication unit 21. The control device 2 is a display in this embodiment, but is not limited to this. The control device 2 can also be a communication device such as a smart phone that can communicate with the router 1.

Each smart lamp 3 includes a light emitting module 31, a communication module 32, and a control module 33 electrically connected to the light emitting module 31 and the communication module 32.

1 and 2, the following describes the flow of the control method of the smart lamp 3 system 100. First, as shown in step S01, the control unit 22 of the control device 2 is connected to the router 1 via the communication unit 21 and joins a multicast group. In this embodiment, the multicast group is related to an Internet protocol address (IP address, for example, 224.8.0.8) and a protocol port (for example, 2925).

Then, as shown in step S02, the control module 33 of each smart lamp 3 is connected to the router 1 via the communication module 32 and joins the multicast group. The order of step S01 and step S02 is not limited to this embodiment, that is, the order in which the control device 2 and the smart lamps 3 join the multicast group is not limited to the aforementioned order.

Then, as shown in step S03, the control unit 22 of the control device 2 generates a control command for controlling the smart lamps 3, and transmits the control command to the router 1. In this embodiment, the control command includes a color value (for example, an RGB value), but it is not limited to this.

Then, as shown in step S04, when the router 1 receives the control command, the router 1 simultaneously transmits the control command to the wisdom in the multicast group through the User Datagram Protocol (UDP) Type lamps 3.

Then, as shown in step S05, when the control module 33 of the smart lamp 3 receives the control command via the communication module 32, the control module 33 decodes the control command and controls the light emitting module according to the control command. Group 31 operates. In this embodiment, the control module 33 controls the light-emitting module 31 to emit light whose color matches the color value according to the color value of the control command.

Next, as shown in step S06, the control unit 22 of the control device 2 determines whether a predetermined update period (for example, 40 mS) is reached, if not, step S06 is executed again, and if so, step S03 is executed again. That is, the control unit 22 of the control device 2 generates the control instruction at the predetermined update cycle and transmits the control instruction to the router 1.

In summary, the intelligent lamp 3 system 100 of the present invention joins the multicast group through the control device 2 and the intelligent lamps 3, and simultaneously transmits the control commands through the router 1 through the user data report protocol.
