Problems solved by technology

[0004] However, in the actual application process, the signal change curve of the PWM adjustment method is uniform and linear, and its slope is gentle and fixed. It cannot be adjusted according to the needs of users, and the PWM adjustment signal source needs to be configured, resulting in high cost.
At the same time, if the frequency of the PWM signal is between 200Hz and 20kHz, the driver of the device to be adjusted will emit noise; the adjustment frequency of the high-end device to be adjusted is higher than 20kHz, but if the frequency is too high, the adjustment range of the driver will be reduced
Therefore, the PWN adjustment method has great limitations

Embodiment 1

[0024] figure 1 It is a flow chart of an automatic adjustment method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the signal to be adjusted outputted by the device to be adjusted is automatically adjusted, for example, it is applicable to the automatic adjustment of the light output by the lighting device Condition. The method can be executed by a control device in the automatic adjustment system, for example, the device can be a unit or a chip integrated in the automatic adjustment system with a control function. Such as figure 1 As shown, the automatic adjustment method includes the following steps:

[0025] Step S101: Obtain the collected environmental signal value.

[0026] Wherein, the environmental signal value may be the light intensity value, temperature value, humidity value, and sound intensity value of the environment. In order to adjust the signal to be adjusted output by the device to be adjusted, it i...

Embodiment 2

[0039] On the basis of the first embodiment, this embodiment provides a continuous automatic adjustment method, image 3 It is a flowchart of a continuous automatic adjustment method provided by Embodiment 2 of the present invention. Continuous automatic adjustment is to adjust the signal to be adjusted corresponding to the environment signal output by the device to be adjusted according to the real-time change of the value of the environment signal, and the adjustment process is continuous. Such as image 3 As shown, the continuous automatic adjustment includes the following steps:

[0040] Step S201: Obtain the collected environmental signal value.

[0041] Step S202: According to the environmental signal value, according to the formula or Calculate the current value I of the device to be adjusted;

[0042] where x 1 is the collected environmental signal value, I max is the maximum output current value of the device to be adjusted, e is a constant, and A is a variat...

Embodiment 3

[0052] Based on the first embodiment, this embodiment provides a discontinuous automatic adjustment method, Figure 4 It is a flow chart of an intermittent automatic adjustment method provided by Embodiment 3 of the present invention. Intermittent automatic adjustment is to select an appropriate discontinuous coefficient according to the value of the environmental signal, and intermittently adjust the signal to be adjusted corresponding to the environmental signal output by the device to be adjusted. For example, when the device to be adjusted is a lighting device, the ambient light at night The intensity value does not change much, and the brightness of the light emitted by the adjusted lighting device does not change much. At this time, the intermittent light adjustment method is more energy-saving on the premise of meeting the needs of users. Such as Figure 4 As shown, intermittent automatic adjustment includes the following steps:

[0053] Step S301: Obtain the collecte...

Abstract

The embodiment of the present invention discloses an automatic adjustment method and system. The method comprises the steps of: obtaining collected environment signal values; determining a current value of a device to be adjusted according to the environment signal values; according to the current value, determining a power value of the device to be adjusted; and adjusting signals to be adjusted corresponding to environment signals output by the device to be adjusted according to the power value. According to the embodiment of the invention, the automatic adjustment method and system can automatically adjust the signals to be adjusted corresponding to the environment signals output by the device to be adjusted according to the change of the environment signal values, and therefore, the power switching rate of the device to be adjusted is improved, and reliability and the stability of the device to be adjusted are enhanced while energy is saved.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic technology, and in particular to an automatic adjustment method and system. Background technique [0002] With the improvement of people's living standards, comfort and energy saving have gradually become the focus of people's attention. Automatic adjustment of the signals output by lighting devices, temperature control devices, and voice control devices has become the mainstream of the development of the intelligent industry. It needs to be adjusted automatically, and it also meets the needs of users for energy saving and environmental protection. [0003] At present, the devices to be adjusted on the market usually use PWM (Pulse Width Modulation, pulse width modulation) regulation method for signal regulation, by periodically turning on and off the device to be adjusted to change the conduction time of the forward current, according to the conduction The power of the device ...
