With the high development of agricultural technology, image processing technology has been widely used in various aspects including visual simulation, online monitoring of agricultural operation process, agricultural product grading, automatic harvesting machinery and so on. In the process of collecting image samples, poor lighting conditions may be caused by environmental problems, which makes it difficult to segment the captured images, which in turn affects the stability of agricultural product monitoring and analysis results; at the same time, in some image processing processes such as image fusion In the research, it is also necessary to analyze the samples with different light intensities. Therefore, the illumination control system is also of great significance to the application of image processing technology in agriculture.

In the lighting control system, the most important part is the light source. A good light source can make the lighting control system achieve better results. Traditional lighting sources are mainly incandescent lamps and fluorescent lamps. These two lamps have low luminous efficiency and high power consumption. Today, the global energy crisis is becoming more and more serious, and they are increasingly unable to meet the requirements of low-carbon environmental protection.

Detailed ways

The light detection module collects the light intensity in real time, and transmits the data to the measurement single-chip microcomputer. After the data is processed, the data is sent to the control single-chip microcomputer control module through the wireless transmission module. The control module uses STC89C52 as the control core, compares the collected light intensity with the threshold light intensity input by the keyboard, and displays the real-time light intensity and the threshold light intensity through the liquid crystal display module. If the real-time light intensity is greater than the threshold, the light intensity of the LED light is reduced through the LED control module, otherwise, the light intensity of the LED light is increased to meet the light requirements for the experiment.

Specific work process

First, initialize the system as a whole, and then set the required light intensity. The set value is assigned to light2, which is completed by an independent button. The measurement single-chip microcomputer measures the ambient light intensity data, and displays the light intensity on the display screen after processing, and then presses the K0 key to perform wireless transmission between the two single-chip microcomputers, and sends the measured light intensity data 1ight1 to the control single-chip microcomputer through Bluetooth, and controls the single-chip display The module displays the currently received light intensity data, and then press the K0 key to adjust the light. If the measured light intensity data light1 is less than the set value light2, increase the duty cycle to increase the LED luminous intensity, otherwise, decrease the duty cycle Reduce the LED luminous intensity.
