Description

Smart Energy Saving Street Lamp

Technical field:

The invention relates to a street lamp control technology.

Background technique:

Today's society advocates energy saving, environmental protection and low-carbon life. How a city can achieve energy conservation and environmental protection is mainly reflected in some public facilities. The urban street lamp is a symbol of urban road facilities. How to reasonably control street lamps and rationally use electric energy will become one of the aspects that reflect the development level of a city. According to statistics, the electric energy invested in street lamps in a city accounts for about a quarter of all lighting electric energy in the city, and nearly 30% to 40% of the electric energy is wasted, that is, when there is no need for lighting Street lamps are still in working condition, causing a waste of electric energy. Moreover, because the street lamps work for a long time and are in the state of being on for a long time, it is easy to shorten the life of the street lamps, so that the street lamps are easy to be damaged, which increases the maintenance amount of the staff, and the replacement cycle is short. If they are not replaced in time, there are likely to be potential safety accidents , and caused secondary waste of capital and labor, etc., a large amount of economic loss is extremely unfavorable for social development.

During the daytime, the street lights will not be on, and the voice-activated switch circuit is in a disconnected state, but when encountering cloudy days, heavy fog or smog and other bad weather, the light will be dimmed and the visibility will be reduced. At this time, the light-activated switch circuit will detect the light intensity Whether it is lower than the specified value 15LUX, after judging that it is lower than the set value, the STC89C52 single-chip control circuit will automatically control the street light to be on. When the weather improves and the light intensity returns to the normal level, after the photosensitive detection of the light-controlled switch circuit, the light-controlled switch circuit will turn off the street lights in time through the STC89C52 single-chip control circuit, so that it will not cause waste of electric energy and bring traffic to the road. For better security,

In the first half of the night, the ordinary lighting method is adopted, that is, all the street lights are turned on to meet the traffic safety of pedestrians and vehicles, and when there is a situation where the street lights are broken and do not light up, the buzzer of the alarm circuit will also send out an alarm in time. On the one hand, it can notify the staff to carry out maintenance, on the other hand, it can also remind pedestrians and vehicles to pay attention to street lamp failure and pay attention to the road conditions.

In the second half of the night, the mode of turning on the street lamps at intervals in the second half of the night is firstly adopted, but when pedestrians or vehicles pass by, the sound change can be detected through the voice-activated switch circuit, so that all the street lights that are not turned on in the energy-saving mode are turned on again, and the recovery is restored. The original lighting level ensures traffic safety.

The operation of the entire control system is based on the timing output of the DS1302 time module, which is the basis for the normal operation of the entire system. The button circuit is to adjust the current time for the clock setting, and the light control switch is used to automatically work when the light intensity is lower than the set value during the day, so as to solve emergencies caused by unmanned control in time. The voice-activated switch is automatically sensed when pedestrians or vehicles pass by in the middle of the night, and the street lights are turned on for a period of time. The LCD display mainly shows the clock time, and the prompt "broken" when the lamp is broken. The alarm is used as an alarm. When the street lamp fails, it will remind the maintenance personnel to repair it in time in the form of an alarm, so as to avoid the inconvenience caused by the lamp failure. .

Compared with the prior art, the present invention has the ability to freely adjust the brightness of street lamps in different periods, so that the lamps can be automatically turned on or off when necessary, and can be self-adapted to achieve the best lighting effect on the outside world, and at the same time successfully It avoids the unnecessary waste of energy caused by the long-time turning on of the light when it is not needed, reduces the trouble of manually turning it off when it needs to be turned off, and greatly prolongs the service life of the light, and truly eliminates waste in details , Energy saving, environmental protection, energy saving and emission reduction advantages.

detailed description:

Now in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

As shown in Figures 1 and 2, the present invention includes STC89C52 single-chip microcomputer control circuit, clock circuit, key setting circuit, light control switch circuit, voice control switch circuit, alarm circuit, LCD1602 display screen display circuit, diode analog street lamp display circuit, key setting circuit Set the working program of the STC89C52 single-chip microcomputer, the STC89C52 single-chip microcomputer control circuit controls the setting of the clock, the on and off of the street lamp and the work of the alarm circuit, the LCD1602 display circuit and the diode analog street lamp display circuit, the light control switch circuit and the voice control switch circuit respectively The electric signal of sensing light and the electric signal of sensing sound are transmitted to the STC89C52 single-chip microcomputer control circuit.

As shown in Figure 3, the sound-activated switch circuit is mainly used to detect the sound intensity of the surrounding environment. This module is used in the energy-saving mode in the middle of the night. When pedestrians or vehicles pass by, the voice-activated switch circuit is in the working state, and the street lights are turned on for a period of time. When the external sound intensity of the voice-activated switch circuit does not reach the preset value, OUT in the voice-activated switch circuit outputs a high level; when the sound intensity of the external environment is greater than the preset value, OUT in the voice-activated switch circuit outputs a low level The high and low levels are detected by the single-chip microcomputer, thereby detecting the sound of the environment.

As shown in Figure 4, the photoresistor module is sensitive to ambient light, and is generally used to detect the intensity of light in the surrounding environment, and then can touch the single-chip microcomputer or relay module, etc. , the DO terminal in the light control switch circuit will output a high level, when the ambient light intensity exceeds the preset value, the DO terminal in the light control switch circuit will output a low level; use a single-chip microcomputer to judge the high level Low level, and then detect the change of the light intensity of the environment according to this, and the output AO of the analog quantity of the small board can be directly connected to the AD module, and through AD conversion, more accurate data of the brightness of the surrounding light can be obtained.

The main flow chart when the present invention works is as shown in Figure 5.

As shown in Figure 6, each control system needs an initial program, and the initial mode of the system is the prerequisite for the system to realize subsequent functions. The present invention adopts serial transmission data, and the source program is downloaded into the single-chip microcomputer through the serial port. Reset the system after it is powered on, and the LCD1602 display screen will display the initial setting value of the clock on the display screen. You can set the current time through the setting button. Press once to set the current time, and press twice to set the street light timing. open time. The initialization program flow is shown in Figure 6. The source program is programmed into the MCU through the serial port circuit. In this design, the USB serial port is not only a serial port line, but also a power supply circuit. It is powered by USB for the operation of the entire system. LCD1602 display screen display circuit is the display module of the whole system, which displays the current time through the display screen.

As shown in Figure 7, the work of the system during the day is to carry out intelligent control modules through photoresistors. During the day, the street lights will not be on, and the voice control module is also in the disconnected state, but when encountering cloudy days, heavy fog or haze and other bad weather, the light will be dimmed and the visibility will be reduced. At this time, the light control switch circuit will detect the light intensity. Whether it is lower than the specified value 15LUX, after judging that it is lower than the set value, the STC89C52 single-chip control circuit automatically controls to turn on the street light. When the weather improves and the light intensity returns to the normal level, after the photosensitive detection of the light-controlled switch circuit, the light-controlled switch circuit will turn off the street lights in time through the STC89C52 single-chip control circuit, so that it will not cause waste of electric energy and bring traffic to the road. For better security.

As shown in Figure 8, the first half of the night refers to the period from 6:00 in the evening to 12:00 in the middle of the night. This period of time belongs to the period of traffic flow of many people and vehicles, so ordinary lighting methods are used, that is, all street lights are turned on. In order to meet the traffic safety of pedestrians and vehicles, and when a street lamp is broken and does not light up, the buzzer of the alarm circuit will also send an alarm in time. On the one hand, it can notify the staff for maintenance, and on the other hand, it can also prompt Pedestrians and vehicles pay attention to street lamp failure and pay attention to road conditions.

As shown in Figure 9, the second half of the night refers to the period from 12:00 midnight to 6:00 am. In the traditional street lighting system, all street lights are basically on from 6:00 pm to 6:00 am. The traffic flow and people flow in the middle of the night will become less. If all the street lights are still turned on, a lot of electric energy will be wasted. In order to make the control system more energy-saving, the mode of turning on the street lights at intervals in the second half of the night is first adopted. This mode can not only save half of the electricity, but also will not have a great impact on the lighting. But when there are pedestrians or vehicles passing by, in order to ensure traffic safety, all the street lights should be turned on to ensure that the road has sufficient lighting, so a voice-activated switch circuit is added on the basis of this energy-saving mode, that is, if there are pedestrians and vehicles When passing by, there will be a sound, and the change of the sound can be detected by the sound-activated switch circuit, so that all the street lights that are not turned on in the energy-saving mode are turned on again, and the original lighting level is restored to ensure traffic safety.
