The sound signal collection unit is used to collect sound signals and send the collected sound signals to the signal processing module. The light signal collection unit is used to collect light intensity.
[0052] In a specific embodiment, the sound signal collection unit is specifically a voice collection board installed on the sound and light control lamp body, and the voice collection board is connected to an amplifier circuit. The voice collection board, i.e., the sound signal collection unit, first passes through the connected amplifier circuit before sending the collected sound signal to the signal processing module. The amplifier circuit is used to amplify the sound signal and send the amplified sound signal to the signal processing module.
[0053] The optical signal collection unit is specifically a light intensity sensor, which is used to detect light intensity, referred to as illumination. In terms of working principle, the light intensity sensor adopts the principle of hot spot effect, and mainly uses detection components that have a high response to weak light. These detection components are actually like the photosensitive matrix of a camera. There is a wound electroplated multi-junction thermopile inside, and its surface is coated with a high-absorption black coating. The hot junction is on the sensing surface, and the cold junction is located in the body. The hot and cold junctions generate a temperature difference potential. Within the linear range, the output signal is proportional to the irradiance. The visible light passing through the filter irradiates the imported photodiode, and the photodiode converts it into an electrical signal according to the visible light illumination. The optical signal collection unit sends the converted electrical signal to the signal processing module;
[0054] The signal processing module is used to process the received sound signal and electrical signal. Specifically, the process of the signal processing module processing the sound signal and electrical signal includes the following steps:
[0055] Step S1: The signal processing module sets an electrical signal reference value U0, and marks the acquired electrical signal sent by the optical signal collection unit as U;
[0056] It should be noted that the optical signal collection unit acquires the electrical signal in a periodic acquisition manner, that is, acquires the signal once at a corresponding period time T, wherein the period time T is set by the control module;
[0057] The signal processing module calculates the received electrical signal U and the set electrical signal reference value U0;

[0064] The acquired sound intensity is a curve of sound intensity changing over time; the starting time of the changing curve is the moment when the signal processing module receives the sound control signal, and the ending time of the changing curve is the moment when the signal processing module receives the power saving signal;
[0065] Step S4: The signal processing module sets the sound intensity boundary value and marks the boundary line in the change curve. The signal processing module sets the determination period, takes the moment when the signal processing module receives the voice control signal as the starting point, calculates the area of the graph where the change curve exceeds the boundary line within the determination period, and marks the area as the detection area, and marks the detection area as S;
[0066] It should be noted that the sound intensity boundary value is obtained by the signal processing module based on a large amount of data processing. At the same time, after the boundary straight line is marked in the change curve, the boundary straight line and the change curve will form a plurality of irregular graphics;
[0067] Step S5: The signal processing module compares the detection area S with the target area S0. When the detection area S is greater than or equal to the target area S0, the signal processing module sends a light-on signal to the control module, and the control module controls the sound and light control lamp body to light up.
[0068] When the detection area S is smaller than the target area S0, the signal processing module sends a normal signal to the control module, and the control module does not perform relevant operations;
[0069] It should be noted that the control module is connected to the signal processing module, and the control module is used to control the sound and light control lamp body to light up;
[0070] In the present application, a delay module is also included, and the delay module is connected to the sound and light control lamp body. When the control module controls the sound and light control lamp body to perform a light-on operation, the delay module starts timing. When the delay period is reached, the delay module connects to the control module and sends an energy-saving signal to the control module. When the control module receives the energy-saving signal sent by the delay module, the control module controls the sound and light control lamp body to perform a light-off operation.
[0071] The sound and light control system disclosed in this embodiment starts from the sound collection and light signal collection, first determines the relationship between the electric signal converted from the light signal and the electric signal reference value, and determines whether the sound control is allowed based on the result of calculating the controllable coefficient. In addition, the influence of different time periods is referred to in the judgment. When the light intensity is sufficient, there is no need to turn on the light and no need for sound control, which fully reflects the concept of energy saving.
[0072] And when sound control is allowed, the sound signal is analyzed to obtain the sound intensity of the sound signal, establish a curve of the change of sound intensity over time, set the sound intensity boundary value and the judgment period, obtain the detection area, and compare it with the target area. When the detection area is greater than or equal to the target area, the signal processing module sends a lighting signal to the control module, and the control module controls the sound and light control lamp body to light up the light. In the operation of lighting the light in accordance with the requirements, the influence of the sound intensity and the duration of the sound is fully considered.

The signal processing module sets the electrical signal reference value. The signal processing module uses the calculation formula to calculate the control coefficient YK. The calculation method of the control coefficient YK is: ; In this calculation formula, is the time correction factor, and , at different time periods, The values are different; Step 2: The signal processing module compares the controllable coefficient YK with 1; when the calculated controllable coefficient YK≥1, the signal processing module sends a high-level signal to the control module, the control module feeds back the sound control signal to the signal processing module, and the signal processing module executes the next step; When the calculated controllable coefficient YK is less than 1, the signal processing module sends a low-level signal to the control module, the control module feeds back a power-saving signal to the signal processing module, and the signal processing module does not work until the calculated controllable coefficient YK is greater than or equal to 1 in the next cycle time, the signal processing module sends a high-level signal to the control module, the control module feeds back a voice control signal to the signal processing module, and the signal processing module executes the next step; Step 3: The signal processing module receives the sound signal in real time, and analyzes the sound signal to obtain the sound intensity of the sound signal; the signal processing module sets the sound intensity boundary value, and marks the boundary straight line in the change curve; the signal processing module sets the determination period, and takes the moment when the signal processing module receives the voice control signal as the starting point, calculates the area of the figure where the change curve exceeds the boundary straight line within the determination period, and marks the area as the detection area, and marks the detection area as S; Step 4: The signal processing module compares the detection area S with the target area S0. When the detection area S is greater than or equal to the target area S0, the signal processing module sends a light-on signal to the control module, and the control module controls the sound and light control lamp body to light up. When the detection area S is smaller than the target area S0, the signal processing module sends a normal signal to the control module, and the control module does not perform any operation.
