Problems solved by technology

[0004] However, in the above-mentioned method of controlling multiple devices, in the "receiving-forwarding" mode, the devices randomly forward after receiving the control command, and a large number of wireless signals are transmitted to the air interface in a short time. This random transmission method is very easy. It causes a large number of wireless signals to collide, consumes air interface resources for a long time until the flooding ends, seriously affects the device itself to receive new control commands, and even affects the normal operation of other devices on the same channel, making the forwarding efficiency of control commands and the success rate of acceptance reduce

Embodiment 1

[0053] The execution subject of the light switch control method proposed in this embodiment, the devices to be controlled at each node, when the control command is obtained, executes the control command and forwards the control command to the device of the adjacent node that has not executed the control command, so as to When controlling multiple devices, it can effectively avoid signal conflicts, prevent signal collisions, quickly forward control instructions, and effectively control multiple devices.

[0054] see figure 1 , this embodiment provides a method for controlling the states of multiple devices, including:

[0055] Step S102, when the control instruction is obtained, the node device obtains the execution status of the control instruction of the adjacent node device.

[0056] Step S102 specifically includes steps (1) to (3);

[0057] (1) The node device judges whether the obtained control command is consistent with the currently executed control command, if yes, th...

Embodiment 2

[0074] see image 3 The system for controlling multiple device states provided in this embodiment includes:

[0075] Execution status acquisition module 30, used for acquiring the control instruction execution status of the adjacent node equipment by the node device when the control instruction is acquired;

[0076] The control instruction forwarding module 31 is used for the node device to determine the adjacent node devices that have not executed the control instruction according to the acquired control instruction execution status of the adjacent node devices, and forward the control instruction to the adjacent node devices that have not executed the control instruction.

[0077] Execution status acquisition module 30, including:

[0078] A control command judging unit, used for the node device to judge whether the obtained control command is consistent with the currently executed control command;

[0079] The control instruction ignoring unit is used to ignore the acquir...

Abstract

The invention provides a method and a system for controlling states of multiple devices, and relates to the technical field of intelligent control. The method comprises steps that when acquiring a control instruction, a node device acquires a control instruction execution state of an adjacent node device; and the node device determines an adjacent node device failing to execute the control instruction according to the control instruction execution state of the first adjacent node device, and forwards the control instruction to the adjacent node device failing to execute the control instruction. Compared with the prior art where a device randomly forwards the control instruction after receiving the control instruction, the provided method is characterized in that signal conflictions can be effectively avoided; collisions between signals are avoided; rapid forwarding of the control instruction is achieved; and multiple devices can be effectively controlled.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to a method and system for controlling the states of multiple devices. Background technique [0002] Modern society has ushered in the era of intelligence, and various intelligent technologies are constantly refreshing people's lives. In daily life, wireless intelligent control technology has been widely used in homes and buildings, such as using remote controllers and mobile APPs to control individual devices. However, this control cannot meet the needs of multiple devices in large-area deployment scenarios. Therefore, how to centrally control multiple devices has become an urgent problem to be solved. [0003] At present, when deploying multiple devices on a large scale, it is necessary to centrally control multiple devices. First, control commands are issued through the control system, and the control commands are randomly forwarded by using a plane-based flooding forwarding m...
