Abstract
Description
Technical Field
[0001] This utility model relates to the field of intelligent lighting control technology, and in particular to an intelligent street light control system with automatically adjustable light intensity. Background Technology
[0002] With the development of modern society, streetlights are almost everywhere. Although we don't come into contact with them as frequently as other household appliances, the development of streetlights is closely related to our lives.
[0003] In reality, most streetlights are manually or timed, and typically use fluorescent or incandescent bulbs. This traditional approach has several drawbacks. Manual control increases labor costs, and timed control may turn on lights when there is sufficient light, eliminating the need for high brightness or even illumination, which is a waste of resources. Conversely, in cloudy or rainy weather, when there is little or no light, the streetlights may not automatically turn on, causing inconvenience to pedestrians. Furthermore, fluorescent or incandescent bulbs generate a lot of heat, resulting in low energy conversion and energy waste.
[0004] Therefore, how to control the on / off state and light intensity of streetlights by changing the ambient light, thereby improving the stability of streetlight control and reducing its energy consumption to meet the needs of daily life, is an urgent problem to be solved. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an intelligent street light control system with automatically adjustable light intensity. This solves the problem that most existing street lights are manually or timed, and typically use fluorescent or incandescent lamps. These traditional street lights have certain drawbacks: manual control increases labor costs; timed control may turn on lights when light is strong and high brightness is not needed, resulting in wasted resources; conversely, in cloudy or rainy weather, when light is weak or nonexistent, the street lights may not automatically turn on, causing inconvenience to pedestrians. Furthermore, fluorescent or incandescent lamps generate significant heat, resulting in low energy conversion and high energy consumption.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0013] Preferably, the main controller module is an STC89C52 microcontroller.

[0018] Preferably, the lighting module is an LED street light with adjustable light intensity.

[0025] This application provides an intelligent street light control system with automatically adjustable light intensity. It effectively solves the problem that most existing street lights are manually or timed, and typically use fluorescent or incandescent lamps. These traditional street lights have certain drawbacks: manual control increases labor costs, and timed control may turn on lights when light is strong and high brightness is not needed, resulting in wasted resources. Conversely, in cloudy or rainy weather, when light is weak or nonexistent, the street lights may not automatically turn on, causing inconvenience to pedestrians. Furthermore, fluorescent or incandescent lamps generate a lot of heat and convert relatively little energy into light, leading to energy consumption. This invention uses a light intensity sensor to capture ambient light and control the brightness and intensity of the street lights. It not only features low power consumption and high stability but is also easy to use, better meeting the needs of daily life.
[0026] Example 1, such as Figure 1 As shown, the technical solution in this application embodiment effectively solves the problem that most existing streetlights are manually controlled or timed, and usually use fluorescent or incandescent lamps. This traditional streetlight has certain drawbacks. Manual control of streetlights increases the cost of manual control. Timed control may turn on the lights when the light is strong and high brightness is not required, which is a waste of resources. Conversely, in cloudy or rainy weather, when the light is weak or there is almost no light, the streetlights cannot turn on automatically, which will cause some inconvenience to pedestrians. In addition, fluorescent or incandescent lamps generate a lot of heat and convert low energy into light energy, which easily leads to energy consumption. The overall idea is as follows: an intelligent streetlight control system with automatically adjustable light intensity, including a light intensity sensor module 1, a threshold setting button module 2, a main controller module 3, a parameter display module 4, a PWM wave light adjustment module 5, and a lighting module 6;
[0027] The light intensity sensor module 1 is electrically connected to the main controller module 3. The light intensity sensor module 1 can transmit the collected light intensity signal to the main controller module 3 for processing.
[0028] The threshold setting button module 2 is electrically connected to the main controller module 3, which is used to set the light intensity threshold.
[0029] The parameter display module 4 is electrically connected to the main controller module 3;
[0030] The PWM light intensity adjustment module 5 is electrically connected to the main controller module 3. When the light intensity is greater than the set threshold, the main controller module 3 sends a signal to the PWM light intensity adjustment module 5 to adjust the light intensity of the lighting module 6.
[0031] In this embodiment, the light intensity sensor module 1 is an SSW-LI607 sensor.
[0032] In this embodiment, the main controller module 3 is an STC89C52 microcontroller.
[0033] In this embodiment, the parameter display module 4 is an LM016 type liquid crystal display screen, which displays the light intensity in real time.
[0034] In this embodiment, the PWM wave adjustment module 5 includes an optocoupler 501 and a driver 502.
[0035] In this embodiment, optocoupler 501 is a TLP521-1 type optocoupler, and driver 502 is an HV9910 type driver.
[0036] In this embodiment, the PWM signal sent by the main controller module 3 is input to the driver 502 after passing through the optocoupler 501, and the driver 502 adjusts the light intensity of the lighting module 6.
[0037] In this embodiment, the lighting module 6 is an LED street light with adjustable light intensity.
[0038] Example 2, as Figure 2 As shown, in order to achieve the above objectives, the present invention provides a control flowchart for an intelligent street light control system with automatically adjustable light intensity (see figure). Figure 2 The control process specifically includes the following steps:
[0039] S1: Initialization, refresh the existing data in the main controller module 3;
[0040] S2: Determine whether to adjust the light intensity threshold. If no adjustment is needed, proceed directly to S3. If adjustment is needed, adjust the light intensity threshold through the threshold setting button module 2.
[0041] S3: Light intensity sensor module 1 collects ambient light intensity signals and transmits them to main controller module 3;
[0042] S4: The main controller module 3 processes the acquired light intensity signal;
[0043] S5: Determine whether the collected light intensity exceeds the threshold. If it exceeds the threshold, proceed to S6; if it does not exceed the threshold, proceed to S7.
[0044] S6: Turn off lighting module 6, then execute S8;
[0045] S7: Turn on the lighting module 6, and send a PWM signal to the optocoupler 5 light intensity sensor module 1 through the main controller module 3, and then input the threshold setting button module 2 of the driver 5 to realize the automatic adjustment of the light intensity of the lighting module 6;
[0046] S8: Parameter display module 4 displays light intensity information;
[0047] S9: Return to S2.
[0048] To address the problems existing in the prior art, this utility model provides an intelligent street light control system with automatically adjustable light intensity. This utility model uses a light intensity sensor to capture ambient light and then controls the on / off state and intensity of the street light. It not only has the characteristics of low power consumption and high stability, but is also easy to use, better meeting the needs of daily life.
[0049] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
