Embodiment 1

[0063] Embodiment 1: Application Scenario of Simple Group Control

[0064] Such as figure 1 As shown, the four Wi-Fi lighting devices are in use for synchronous switch operation, so these four Wi-Fi lighting devices are divided into a control group G, and a local unique group MAC is assigned to this group during the grouping process address.

[0065] The user pairs a wiring-free Wi-Fi lighting switch S with the group of Wi-Fi lighting devices, and the Wi-Fi lighting switch uses the group MAC address as the destination address to send all four Wi-Fi The Fi lighting device sends a single control packet to realize the synchronous control of the Wi-Fi lighting devices in the group.

[0066] The Wi-Fi Light Switch and the four Wi-Fi Lighting devices each have a globally unique MAC address to uniquely identify a single device.

[0067] The control information packet exchange between the Wi-Fi lighting switch and the Wi-Fi lighting device group may be based on MAC layer link, or...

Embodiment 2

[0072] Embodiment 2: An application scenario where Wi-Fi lighting devices belong to multiple groups

[0073] Such as figure 2 , image 3 As shown, there are a large number of Wi-Fi lighting devices in a large lighting space, and their control requirements fall into the following two categories:

[0074] a) The synchronous control of all devices can be realized by one or a group of wiring-free Wi-Fi lighting switches;

[0075] b) The synchronous control of special modes of some devices (such as banquet mode, conference mode, etc.) can be realized by another Wi-Fi lighting switch without wiring or smart terminal applications.

[0076] According to the above two types of control requirements, all lighting devices in the lighting space are classified into one group——Wi-Fi lighting device group G1, and the group MAC address of G1 is assigned; The lighting devices are classified into two other groups—Wi-Fi lighting device groups G2 and G3, and assign a group MAC address to G2 ...

Embodiment 3

[0081] Embodiment 3: The application scenario where the Wi-Fi lighting switch belongs to multiple groups

[0082] Such as Figure 4 As shown, there are three groups of Wi-Fi lighting device groups G1 , G2 and G3 in one lighting space, and each group is assigned a respective group MAC address. The user needs to control the three-button Wi-Fi switch at two positions in the space; the three buttons of each three-button Wi-Fi switch use the group MAC addresses of the three Wi-Fi lighting equipment groups as the destination address , for example, when the user touches three buttons correspondingly, the corresponding control of three Wi-Fi lighting device groups is realized (for example, S11 or S21 is paired with G1; S12 or S22 is paired with G2; S13 or S23 is paired with G3), Figure 4 Only the control packet P1 sent by the switch S11 to the group G1 is shown as an example.

[0083] In view of the result of controlling the Wi-Fi lighting equipment, it can be directly displayed ...

Abstract

The invention relates to a group gang control system and method based on a group MAC (Media Access Control) address for a plurality of pieces of Wi-Fi Internet of things equipment. The plurality of pieces of Wi-Fi Internet of things equipment are grouped to form a plurality of equipment groups; each equipment group has a local unique group MAC address in order to uniquely identify the equipment group; a plurality of pieces of Wi-Fi Internet of things master control equipment are provided; the group MAC address of any equipment group which is matched with each piece of master control equipment is taken as a target address for transmitting information; and synchronous control or synchronous data transmission is performed on all controlled equipment in the equipment groups. Group operation is performed on a large amount of Wi-Fi Internet of things equipment with similar functions through the group MAC address, so that the data packet transmitting quantity can be reduced; the control process is simplified; and the reaction speed of the controlled equipment is increased.

Description

technical field [0001] The present invention relates to the field of Internet of Things devices, in particular to a system and method for grouping collective control of multiple Wi-Fi Internet of Things devices based on group MAC addresses. Background technique [0002] The Internet of Things, namely Internet Of Things (IoT). IoT devices can be various information sensors and controllers, as well as various intelligent household appliances. IoT devices are connected to the Internet in various ways to form a huge network, realizing the extension of the Internet from people to things. [0003] The Wi-Fi IoT access method is one of the most widely used, lowest cost, and best scalable IoT access methods. Usually, a Wi-Fi IoT device directly accesses the network through a Wi-Fi access point (Wi-Fi Access Point, also called a Wi-Fi hotspot or a wireless router). At present, there are many household or commercial Wi-Fi IoT devices emerging on the market. Most of these Wi-Fi IoT...
