Abstract

The invention discloses a device state synchronous control device and a synchronous control method, including a power supply module, a line voltage detection module, a control module and a wireless module; the power supply module rectifies the input alternating current and outputs the line voltage to the line voltage detection module; the line voltage The detection module outputs a detection signal to the control module according to the line voltage; the wireless module receives the externally input state data and stores it in the control module; the control module counts according to the detection signal, and reads when the detection signal output is interrupted and the count value is the first set value Get the currently stored state data, output the corresponding dimming signal to the controlled device according to the current count value and state data, and clear the count value when the count value is the second set value. When adjusting the working states of a plurality of devices at the same time, the present invention uses the detection signal output interruption as a synchronous signal, and uses the count value as a state change cycle to control the working states of the devices, effectively eliminating the influence of wireless command transmission distance and rate on state synchronization.

Description

technical field

[0001] The invention relates to the technical field of intelligent control, in particular to a device state synchronization control device and a synchronization control method. Background technique

[0002] At present, when using a wireless controller to control the status of multiple independent devices, due to reasons such as low wireless data transmission rate or long distance between devices, the time for each device to receive the controller instruction is quite different. In the traditional processing method, the device does not As a synchronization processing mechanism, the device will update its own state to the state set by the controller after receiving the wireless control command. The state of the device that receives the wireless command first changes first, and the state of the device that receives the wireless command changes later. It is a dynamic change according to a certain law, which will cause the device state change after receiving the c...
