Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 As shown, a method for avoiding light flicker in energy-saving control, including:

[0023] Step 1. Convert the photosensitive signal into a digital signal and define it as the current photosensitive value;

[0024] Step 2. Determine whether the light-off value needs to be adjusted. If it is necessary to adjust the light-off value, read the current photosensitive value and the light-on value, and judge whether the photosensitive value is greater than the light-on value. If it is greater than the light-on value, set the light-off value equal to Add 6 to the photosensitive value, if it is not greater than the light-on value, set the light-off value equal to the light-on value plus 8;

[0025] Step 3. If there is no need to adjust the light-off value and the current light-off value is valid, return to step 1 and start a new round ...

Abstract

The invention discloses a method for avoiding lamp flashing in energy conservation control and a photosensitive sampling circuit. The method comprises the steps of 1, converting a photosensitive signal into a digital signal to be defined as the current photosensitive value; 2, judging whether the turn-off value needs to be adjusted or not, if the turn-off value needs to be adjusted, reading the current photosensitive value and a turn-on value, and judging whether the photosensitive value is greater than the turn-on value or not, if so, setting the turn-off value to be equal to the summation of the photosensitive value and a set return difference value, and if not, setting the turn-off value to be equal to the summation of the turn-on value and the set return difference value; and 3, if the turn-off value does not need to be adjusted, proving that the current turn-off value is effective, and returning to the step 1 and re-performing judgment for the next round. The method is applied to the illumination energy conservation control; and by adoption of the method, lamp flashing can be avoided effectively, the turn-on or turn-off of the lamp can be controlled with high sensitivity and high precision according to the ambient light luminance, so that it is ensured that the ambient light luminance value can be within the range of the internal standard requirement, and an energy-saving effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of energy-saving control, in particular to a method for avoiding lamp flicker in energy-saving control and a photosensitive sampling circuit. Background technique [0002] In lighting energy-saving control, the ambient light intensity is one of the main input parameters of the system. It is necessary to accurately detect the light intensity and check whether it reaches the set value. The photosensitive circuit detects the light intensity, and the microprocessor processes the detected signal, compares the relationship between the light intensity and the set light-on value and light-off value, and outputs control parameters to the actuator circuit in time to control the light on or off. In the application process of the hardware photosensitive circuit, serious problems have gradually been exposed: the photosensitive light-on point and the light-off point are not easy to adjust, and it is easy to appear "flicke...
