[0043] Example 1:

[0044] like Figures 1 to 3 As shown, this disclosure provides an intelligent street light 10 with current and voltage monitoring functions, including a street light 10, a power management module 20, a data acquisition module 21, a communication module 22, and a control device 23. The output terminal of the power management module 20 is electrically connected to the control device 23. The data acquisition module 21 is installed on the street light 10 and includes a current sensor, a voltage sensor, an environmental sensor, a power acquisition unit, and an electricity meter. The output terminal of the data acquisition module 21 is electrically connected to the control device 23. The input terminal of the communication module 22 is electrically connected to the control device 23, and the output terminal of the communication module 22 is used to electrically connect to the central management system 24.

[0045] The control device 23 serves as the core of the control system, handling data acquisition, processing, and control output. Specifically, it receives information from the data acquisition module 21, processes this data according to preset rules or algorithms, and then makes corresponding control decisions (such as adjusting brightness to save energy).

[0046] The data acquisition module 21 consists of multiple sensors that can monitor the operating status of the streetlight 10 (such as current and voltage), environmental conditions (such as light intensity and temperature), and other relevant information (such as power consumption). Specifically, the output terminals of each sensor (current sensor, voltage sensor, environmental sensor, power acquisition unit, and electricity meter) of the data acquisition module 21 are connected to the analog input pin (ADC) of the control device 23.

[0047] The power management module 20 is designed to provide a stable power supply for the entire system. Specifically, the output of the power management module 20 is connected to the power pin of the control device 23 to provide a stable DC voltage.

[0048] The communication module 22 is used to transmit data with the central management system 24, enabling the smart streetlights 10 to exchange data with the central management system 24 or other related devices. Through network connectivity, management can remotely monitor the status of each streetlight 10, promptly detect faults and arrange maintenance, and optimize the overall lighting strategy to achieve energy conservation and emission reduction. Specifically, the input terminal of the communication module 22 is connected to the communication pin of the control device 23.

[0049] Through the above technical solution, the street light 10, power management module 20, data acquisition module 21, communication module 22 and control device 23 work together to not only provide lighting, but also integrate multiple monitoring functions. They can monitor electrical parameters such as current and voltage, as well as environmental conditions (such as temperature and humidity) in real time, and transmit these data to the central management system 24 through the communication module 22.

[0050] To ensure the accuracy and reliability of data acquired from various sensors, optionally, such as Figure 1 As shown, the intelligent street light 10 also includes a signal conditioning module 25, which includes an amplifier and a filter.

[0051] Since the signals generated by the sensors are often very weak and insufficient to be directly recognized and used by the control device 23 or other processing units, the amplifier can amplify these weak electrical signals to a suitable level, making subsequent processing easier and more accurate.

[0052] Since the signals collected by sensors are often affected by various noises, such as electromagnetic interference, filters can remove or reduce these unwanted noises and retain useful signal components, thereby improving the quality and accuracy of the data.

[0053] By introducing the signal conditioning module 25, the accuracy and stability of the intelligent street light 10 system in monitoring environmental changes and its own working status can be significantly improved, further enhancing the performance of the intelligent street light 10.

[0054] To improve system security and reliability, optionally, such as Figure 1 As shown, the smart street light 10 also includes a vacuum contactor 26, through which the street light 10 establishes a connection.

[0055] The vacuum contactor 26 controls the connection between the street light 10 and the power supply, enabling precise control of the street light 10, such as timed switching and dimming functions. Simultaneously, it can quickly disconnect the circuit upon detecting abnormal conditions (such as overcurrent or short circuits), protecting the street light 10 from damage and ensuring the safety of pedestrians and vehicles. In short, the addition of the vacuum contactor 26 not only enhances the functionality of the intelligent street light 10 but also strengthens the overall safety and stability of the system.

[0056] Optionally, such as Figure 1 As shown, the intelligent street light 10 also includes a control output module 27, which is electrically connected to the control device 23.

[0057] The control output module 27 can directly drive the street light 10 to perform operations such as switching on and off, and dimming. For example, when the control device 23 determines that the street light 10 needs to be turned on or off based on the ambient light intensity, the control output module 27 will receive this instruction and execute the corresponding action.

[0058] In addition to simple on / off control, the control output module 27 can also continuously adjust the brightness of the streetlight 10. This is typically achieved through pulse width modulation (PWM) technology, which adjusts the luminous intensity of the lamp by changing the duty cycle of the output signal, thereby achieving energy-saving effects.

[0059] The control output module 27 can also communicate with other external devices (such as other smart streetlights 10, environmental monitoring equipment, etc.) to achieve coordinated control. For example, all streetlights 10 in an area can adjust their brightness uniformly according to the instructions of the central management system 24, or automatically turn on when pedestrians or vehicles are detected approaching.

[0060] The control output module 27 can also integrate fault detection functions, such as overcurrent protection and short-circuit protection. Once an abnormality is detected, it can immediately take measures, such as cutting off the power supply to prevent equipment damage, and reporting fault information to the control device 23 for timely handling.

[0061] To adapt to different application scenarios and needs, the control output module 27 can provide a variety of output interfaces, such as relay output, analog output, and digital output, so that users can choose the appropriate control method according to the actual situation.

[0062] Optionally, such as Figure 1 As shown, the intelligent street light 10 also includes a human-machine interaction module 28, which is electrically connected to the control device 23. The integration of the human-machine interaction module 28 into the intelligent street light 10 system greatly enhances the user experience and management convenience. The electrical connection between the human-machine interaction module 28 and the control device 23 enables two-way communication between the user and the intelligent street light 10.

[0063] The application scenario is public places, such as parks, squares, pedestrian streets, etc. Users can query and control nearby street lights 10 through the human-computer interaction module 28.

[0064] The application scenario is a residential area, where residents can adjust the brightness of the streetlights 10 in the community through the human-computer interaction module 28 to improve living comfort.

[0065] The application scenario is in commercial areas. Merchants can set the on / off time and brightness of the advertising light box through the human-computer interaction module 28 to save energy.

[0066] As one implementation method, such as Figure 2 and Figure 3 As shown, the street light 10 includes a lighting lamp 11, a lamp post 12, a brightness monitoring mechanism 13, and a brightness adjustment mechanism. The lighting lamp 11 is located on the top of the lamp post 12. The brightness monitoring mechanism 13 is located on the lighting lamp 11 or the lamp post 12 and is used to monitor the brightness of the working environment where the lighting lamp 11 is located. The brightness adjustment mechanism is located on the lighting lamp 11 or the lamp post 12 and is electrically connected to the lighting lamp 11 to control the brightness of the lighting lamp 11. The control device 23 is located on the lamp post 12 and is electrically connected to both the brightness monitoring mechanism 13 and the brightness adjustment mechanism.

[0067] The brightness monitoring mechanism 13 can be installed on the lighting lamp 11 or the lamp post 12 to monitor the brightness of the environment around the lighting lamp 11. Specifically, it can convert the brightness information into an electrical signal and send it to the control device 23.

[0068] Optionally, the brightness monitoring mechanism 13 may include a photosensitive sensor that can sense the intensity of natural light or ambient artificial light sources.

[0069] The brightness adjustment mechanism can be installed on the lighting lamp 11 or the lamp post 12 and is electrically connected to the lighting lamp 11 to directly control the brightness of the lamp. Specifically, the brightness of the lighting lamp 11 can be adjusted according to the instructions of the control device 23.

[0070] Alternatively, pulse width modulation (PWM) technology or other dimming methods can be used to control the brightness of the LED lights.

[0071] The control device 23 is installed inside or outside the lamp post 12. The control device 23 is electrically connected to the brightness monitoring mechanism 13 and the brightness adjustment mechanism to form a closed-loop control system. Specifically, the control device 23 is used to receive and process data from the brightness monitoring mechanism 13. It can determine whether the brightness of the lighting lamp 11 needs to be adjusted according to a preset algorithm or logic, and send a control signal to the brightness adjustment mechanism to achieve dynamic adjustment of the brightness of the lighting lamp 11.

[0072] When the ambient brightness changes, the brightness monitoring mechanism 13 detects this change and converts the brightness value into an electrical signal, which is then transmitted to the control device 23. The control device 23 compares the current brightness value with a preset standard value to determine whether the brightness of the lighting lamp 11 needs to be adjusted. If adjustment is required, the control device 23 sends a corresponding control signal to the brightness adjustment mechanism. The brightness adjustment mechanism adjusts the current or PWM signal of the lighting lamp 11 according to the received control signal, thereby changing the brightness of the lighting lamp 11 to adapt to the needs of the current environment. This design not only improves the energy efficiency of the street light 10 and reduces unnecessary energy waste, but also improves the safety of vehicles and pedestrians at night. In addition, such a control system can integrate more intelligent functions, such as connecting to the central management system 24 via the communication module 22 to achieve remote monitoring and management.

[0073] As one implementation method, such as Figure 2 and Figure 3 As shown, the lighting lamp 11 includes a lamp body 112, a lamp shade 113, and a housing 114. The lamp post 12 includes a first section 121 and a second section 122 connected together. The first section 121 and the second section 122 are set at an angle. The end of the first section 121 away from the second section 122 is connected to the ground. The first end of the housing 114 is closed, and the second end of the housing 114 is open. The first end of the housing 114 is connected to the side of the second section 122 facing the ground. The lamp shade 113 covers the second end. The lamp body 112 is set inside the housing 114 and close to the second end. The brightness adjustment mechanism is set inside the housing 114, and the brightness monitoring mechanism 13 is set outside the cylindrical housing 114.

[0074] Among them, the lamp body 112, as the core part of the lighting lamp 11, can be an LED lamp.

[0075] The lampshade 113 covers the lamp body 112 to protect the lamp body 112 from external environmental influences (such as rain, dust, etc.) and also diffuses the light to make the lighting more uniform.

[0076] The housing 114 is used to house components such as the lamp body 112 and the brightness adjustment mechanism.

[0077] The first section 121, which connects to the ground, can be fixed to a concrete foundation to ensure the stability of the entire street light 10.

[0078] The second segment 122 is set at a certain angle to the first segment 121, so that the road or specific area can be better illuminated.

[0079] The brightness monitoring mechanism 13 is located outside the cylindrical housing 114. This design allows the brightness monitoring mechanism 13 to be directly exposed to the environment, enabling more accurate measurement of the actual brightness of the surroundings and avoiding errors caused by the housing 114 blocking the light.

[0080] The brightness adjustment mechanism is located inside the housing 114. This protects the adjustment mechanism from external factors such as weather, extending its service life.

[0081] As one implementation method, such as Figure 2 and Figure 3 As shown, the lamp body 112 includes a first lamp body and a second lamp body. The light intensity of the first lamp body is greater than that of the second lamp body. The brightness adjustment mechanism is electrically connected to the first lamp body and / or the second lamp body and is used to control the opening or closing of the first lamp body or the second lamp body.

[0082] The brightness monitoring mechanism 13 continuously monitors the ambient brightness and sends the data to the control device 23. The control device 23 determines the required lighting intensity based on a preset threshold or algorithm. The control device 23 then sends a command to the brightness adjustment mechanism to control the opening or closing of the first or second lamp. After brightness adjustment, the brightness monitoring mechanism 13 continues monitoring, forming a closed-loop control system to ensure that the lighting always meets the set requirements.

[0083] When the brightness monitoring mechanism 13 detects that the ambient brightness is high enough (e.g., during the day), the brightness adjustment mechanism can turn off all the lamps 112 to save energy. When the ambient brightness is at a moderate level (e.g., at dusk or dawn), the brightness adjustment mechanism can turn on only the second lamp to provide moderate lighting. When the ambient brightness is very low (e.g., at night), the brightness adjustment mechanism can turn on the first lamp, or even turn on both the first and second lamps simultaneously, to provide sufficient lighting. By using high-brightness and low-brightness lamps 112 differently, energy consumption can be minimized while meeting lighting needs. The lighting intensity can be flexibly adjusted according to actual needs, which can improve the adaptability of the street light 10 and the user experience. Low-brightness lamps 112 can be used when strong light is not needed, which can reduce the frequency of use of high-brightness lamps 112, thereby extending the lifespan of the entire smart street light 10.

[0084] In one implementation, the control device 23 includes a processor and a comparator, which are electrically connected. The comparator is electrically connected to the brightness monitoring mechanism 13. The comparator is used to compare the brightness signal received from the brightness monitoring mechanism 13 with a preset brightness threshold. The processor is electrically connected to the brightness adjustment mechanism.

[0085] The brightness monitoring unit 13 (e.g., a photosensor) continuously monitors the ambient brightness and converts the brightness signal into an electrical signal, which is then sent to the comparator.

[0086] The comparator receives the brightness signal from the brightness monitoring unit 13 and compares the received actual brightness signal with preset brightness thresholds. These thresholds can be pre-programmed values ​​representing the ideal brightness level under different time periods or environmental conditions.

[0087] The comparator sends the comparison result (e.g., brightness is higher than, equal to, or lower than a threshold) to the processor. The processor processes the received information according to a preset algorithm and logic. For example, if the actual brightness is lower than the threshold, the processor may decide to increase the brightness; if it is higher than the threshold, it may decide to decrease the brightness or turn off the lamp 112.

[0088] The processor sends control commands to the brightness adjustment mechanism based on the processing results. The brightness adjustment mechanism controls the first or second lamp body to turn on or off, or adjusts their brightness, based on the commands.

[0089] In other words, through the collaboration of the comparator and the processor, the system can perform fine-tuned brightness adjustment based on the actual ambient light level, ensuring that the lighting meets the needs while saving energy. Furthermore, the preset brightness threshold can be adjusted according to different times and seasons, allowing the streetlight system to adapt to various environmental conditions. Additionally, by monitoring and adjusting brightness in real time, the system can maximize energy savings while maintaining effective lighting.
