Problems solved by technology

[0003] 1. The dimming control is not convenient and quick, and the smart dimmer needs APP intervention to control it;
[0004] 2. When the dimmer is abnormal, there is no protection measure, and the control circuit cannot be effectively protected, which has potential safety hazards
For example, the "Voice Controlled Light" disclosed in the application number 201521093224.8, but its control method is relatively simple and does not have the function of real-time interaction

Embodiment Construction

[0032] The specific implementation of the present invention will be further analyzed below in conjunction with the drawings and embodiments. The following exemplary embodiments are used to explain the present invention, but not to limit the present invention.

[0033] Such as figure 1 As shown, a multifunctional dimmer based on the Internet of Things uses a single-chip ESP32 processor as the main controller, and multiple slave controllers are connected to the input or output pins of the main controller, including:

[0034] Speech perception and audio processor, including two silicon microphones of model NSM0418DT, which are used to collect voice signals and convert the voice signals into pulse density modulation signals, and then transmit the pulse density modulation signals to the DSP audio processor, and the audio processor is used for The pulse density modulation signal is converted into a digital signal of 0 or 1. After the digital signal is modified, deleted, enhanced an...

Abstract

The invention discloses a multifunctional dimmer based on the Internet of things, which comprises a master controller and a plurality of slave controllers connected with the master controller. Each slave controller includes a voice perception and audio processor, a touch detection circuit, a silicon controlled rectifier dimmer circuit, a zero-crossing detection circuit, a wireless communication module, and the like. The multifunctional dimmer of the invention is used to improve the convenience of dimming of lighting devices, has a variety of control modes such as voice control, touch control and remote control, and is suitable for incandescent lamps, halogen lamps and adjustable LED lamps.

Description

technical field [0001] The invention relates to the field of dimming of lighting devices, in particular to a multifunctional dimmer based on the Internet of Things. Background technique [0002] Thyristor dimmer is a commonly used dimming device at present. Its basic principle is to adjust the chopping phase of the thyristor to control the conduction angle of the thyristor. By reducing or increasing the RMS voltage, the light of the average power can produce different intensities. light output. At present, the mainstream dimmers are controlled by mechanical buttons or rotary controls. For example, the "dimmer" disclosed in the application number 201210535280.7 uses a rotary variable resistor as a control method. In recent years, smart dimmers have appeared, such as a "wireless control smart dimmer" disclosed in the application number 201620397949.4, which adds a wireless communication module to the original dimmer, which can support mobile terminal APP application program c...
