[0054] Reference Figure 1 , Figure 1 This is a structural schematic diagram of the first embodiment of the intelligent city street light of this utility model. This utility model proposes a first embodiment of an intelligent city street light.

[0055] In this embodiment, the smart city street light includes: a photosensitive device 10, a microcontroller unit 20, and a light source control unit 30; one end of the photosensitive device 10 is connected to the first end of the microcontroller unit 20, and the second end of the microcontroller unit 20 is connected to the light source control unit 30.

[0056] It should be noted that the photosensitive device 10 can be used to collect the light intensity information of the environment surrounding the smart city street light, convert the light intensity information into a light intensity electrical signal, and transmit the light intensity electrical signal to the microcontroller unit 20. The microcontroller unit 20 can be used to generate a light-emitting drive signal whose amplitude is linearly negatively correlated with the light intensity electrical signal, and transmit the light-emitting drive signal to the light source control unit 30. The light source control unit 30 can be used to drive the LED module of the smart city street light to provide illumination according to the amplitude of the light-emitting drive signal.

[0057] The photosensitive device 10 can be an electrical device with photoelectric conversion function, capable of converting light signals into electrical signals. For example, it can be an optical sensor, a photoresistor, or a photodiode. The light intensity information can be analog information reflecting the ambient light intensity around the streetlight. The light intensity electrical signal is a voltage signal generated by the photosensitive device 10 in response to the light intensity information. The amplitude of the light intensity electrical signal increases with increasing light intensity and decreases with decreasing light intensity.

[0058] Furthermore, the microcontroller unit 20 can be a functional device with signal transmission and processing capabilities, capable of implementing signal transmission and control functions through pre-programmed and stored software. It controls the output port to generate corresponding electrical signal outputs based on the electrical signal information from the input port. For example, it can be a microcontroller unit (MCU).

[0059] It should be understood that the photosensitive device 10 can transmit a light intensity electrical signal representing the illuminance around the streetlight to the microcontroller unit 20. The microcontroller unit 20 can generate a light-emitting drive signal at a port corresponding to the light source control unit 30 according to a pre-set software program. The amplitude of the light-emitting drive signal is linearly negatively correlated with the amplitude of the light intensity electrical signal. That is, the larger the amplitude of the light intensity electrical signal, the smaller the amplitude of the light-emitting drive signal, and vice versa.

[0060] In one possible implementation, the linear negative correlation mapping between the light-emitting driving signal and the light intensity electrical signal can also be achieved through a negative feedback control circuit. By loading the light intensity electrical signal at the reverse end, the negative correlation between the light-emitting driving signal and the light intensity electrical signal can be achieved.

[0061] It should be noted that intelligent city streetlights can use high-efficiency LED modules for light emission control. The light source control unit 30 can be a driving circuit that drives the LED module to emit light, and can control the luminous power of the LED module according to the amplitude of the light emission driving signal to achieve brightness adjustment of the streetlight. The light source control unit 30 can adjust the luminous power of the LED module by controlling the voltage of the LED module, the duty cycle of the PWM wave, etc., according to the light emission driving signal.

[0062] Furthermore, a filter circuit and a boost circuit (not shown in the figures) can also be provided between the photosensitive device 10 and the microcontroller unit 20 to make the light intensity acquisition more accurate.

[0063] This embodiment proposes an intelligent city street light, comprising: a photosensitive device, a microcontroller unit, and a light source control unit. One end of the photosensitive device is connected to a first end of the microcontroller unit, and a second end of the microcontroller unit is connected to the light source control unit. The photosensitive device collects illuminance information of the surrounding environment of the intelligent city street light, converts the illuminance information into a light intensity electrical signal, and transmits the light intensity electrical signal to the microcontroller unit. The microcontroller unit generates a light-emitting drive signal whose amplitude is linearly negatively correlated with the light intensity electrical signal, and transmits the light-emitting drive signal to the light source control unit. The light source control unit drives the LED module of the intelligent city street light to provide illumination based on the amplitude of the light-emitting drive signal. The brightness of the light is controlled by the illuminance. The street light power is reduced when the light is strong, avoiding resource waste caused by untimely adjustments to the street light due to seasonal light differences.

[0064] Reference Figure 2 , Figure 2 This is a structural schematic diagram of the second embodiment of the intelligent city street light of this utility model. Based on the first embodiment of the intelligent city street light described above, a second embodiment of the intelligent city street light of this utility model is proposed.

[0065] The intelligent city street light also includes a communication module 40; the communication module 40 is connected to the microcontroller unit 20 and also to a terminal.

[0066] It should be noted that the microcontroller unit 20 can also be used to transmit the optical intensity signal to the communication module 40. The communication module 40 can be used to send the optical intensity signal to the terminal.

[0067] The communication module 40 can include wired communication, wireless communication, and fiber optic communication. No specific limitations are imposed in this embodiment. It has the capability to transmit signals from smart city streetlights over long distances. The terminal can be a backend terminal for city government departments (including but not limited to road administration, public safety management, and environmental departments) that need to access streetlight data. The smart city streetlight achieves signal transmission capability through communication between the communication module 40 and the terminal.

[0068] In one possible implementation, the communication module 40 can also be used to receive the cross-silence drive signal from the terminal and transmit the cross-silence drive signal to the microcontroller unit 20; the microcontroller unit 20 can also be used to reduce the amplitude of the light emission drive signal when the cross-silence drive signal is low.

[0069] It should be understood that in some urban roads, streetlights are redundantly arranged, so activating them simultaneously would waste electrical resources. The cross-silencing function allows one of two adjacent streetlights to operate normally while the other reduces its power output appropriately without interfering with traffic.

[0070] The cross-silence drive signal can be a communication transmission signal issued by the road administration central control terminal. It can be a high-level or low-level signal. The high-level cross-silence drive signal is transmitted to the normally lit streetlights, and the low-level cross-silence drive signal is transmitted to the streetlights that need power reduction. The cross-silence drive signal is transmitted to the microcontroller unit 20 via the communication module 40. When the microcontroller unit 20 receives the low-level cross-silence drive signal, it reduces the amplitude of the output light-emitting drive signal. This can be achieved through a preset software program or through a subtraction control circuit. The amplitude of the reduced light-emitting drive signal can be set according to the preset low-power operating conditions of the streetlights, which will not be described in detail in this embodiment. Maintenance personnel can remotely control the streetlights through the developed APP terminal for manual intervention in switching the streetlights on and off or for maintenance and debugging.

[0071] Furthermore, the smart city street light also includes a camera device 50; the camera device 50 is connected to the communication module 40. The camera device 50 can be used to collect image information of a preset area of ​​the smart city street light, temporarily store the image information, and transmit the temporarily stored image information to the terminal through the communication module. In this case, the terminal can be the computer room terminal of the road administration department. The image information can be transmitted via optical fiber, which has a faster transmission rate and higher transmission stability. The preset area for image information collection can be set according to the location of the street light in the city.

[0072] In one possible implementation, the smart city street light further includes: an alarm button 60; the alarm button 60 is connected to the camera device 50; the alarm button 60 can be used to generate an alarm drive signal when triggered, and transmit the alarm drive signal to the camera device 50; the camera device can also be used to transmit image information temporarily stored for a first preset time before receiving the alarm drive information and image information temporarily stored for a second preset time after receiving the alarm drive information to the terminal through the communication module when receiving the alarm drive information.

[0073] It should be noted that the alarm button can be either a push-button type or a toggle type; no specific limitation is made in this embodiment. When the button is triggered, an alarm drive signal is generated by activating the power supply circuit and transmitted to the camera device. The image information stored by the camera device is also time-related during storage. Based on the time the alarm drive signal is received, the camera device temporarily stores image information for a period of time before (a first preset time, e.g., 5 minutes) and a period of time after (a second preset time, e.g., 5 minutes) and transmits it to the terminal through the communication module. At this time, the terminal can be a public safety management system, realizing the alarm function in emergency situations.

[0074] Furthermore, the intelligent city street light may also include: an environmental sampling and detection unit 70; the environmental sampling and detection unit 70 is connected to the microcontroller unit 20.

[0075] It should be noted that the environmental sampling and detection unit can be used to collect meteorological information of the environment around the smart city streetlights, convert the meteorological information into environmental electrical signals, and transmit the environmental electrical signals to the microcontroller unit; the microcontroller unit can also be used to transmit the environmental electrical signals to the communication module; the communication module can also be used to send the environmental electrical signals to the terminal.

[0076] It should be understood that meteorological information may include data such as atmospheric particulate matter and wind direction and speed, which are needed by environmental monitoring departments. This data can be collected by atmospheric monitoring sensors, converting the corresponding simulated environmental data signals into environmental electrical signals, and then transmitting them to the terminal via a communication module. In this case, the terminal can be the server of the environmental monitoring department. This allows for the sharing of multiple poles, reducing the number of roadside poles and freeing up public space resources.

[0077] Reference Figure 3 , Figure 3 This is a structural schematic diagram of the third embodiment of the intelligent city street light of this utility model. Based on the above embodiments of the intelligent city street light, a third embodiment of the intelligent city street light of this utility model is proposed.

[0078] The smart city street light also includes a display module 80. The display module 80 is connected to the microcontroller unit 20 and also to the communication module 40.

[0079] It should be noted that the microcontroller unit can also be used to generate a display drive signal according to a preset system time and transmit the display drive signal to the communication module; the communication module can also be used to receive video information output by the terminal and transmit the video information to the display module when the display drive signal is received; the display module can be used to display the received video information.

[0080] It should be understood that the preset system time can be set according to the pedestrian traffic periods at the location of the smart city streetlights. During peak pedestrian traffic periods, a display drive signal is generated and transmitted to the communication module, which then controls the communication module to send the terminal's video information to the display module for display. The video information may include news and advertising information.

[0081] Furthermore, the intelligent city street light also includes an intelligent traffic component 90; the intelligent traffic component 90 is connected to the microcontroller unit 20.

[0082] It should be noted that the intelligent transportation component can be used to collect traffic condition information around intelligent city streetlights, convert the traffic condition information into traffic electrical signals, and transmit the traffic electrical signals to the microcontroller unit; the microcontroller unit can also be used to transmit the traffic electrical signals to the communication module. The communication module can also be used to send the traffic electrical signals to the terminal. In this case, the terminal can be an intelligent transportation system, capable of accessing traffic facilities such as traffic lights and traffic networks, and transmitting data to the network of road vehicles.

[0083] In one possible implementation, the smart city street light may further include: a fault testing unit; (not shown in the figure) the fault testing unit is connected to the LED module, and the fault testing unit is also connected to the microcontroller unit.

[0084] The fault testing unit can be used to collect the operating current of the LED module, compare the operating current with a preset current range, generate a fault indication signal when the operating current exceeds the preset current range, and transmit the fault indication signal to the microcontroller unit; the microcontroller unit can also be used to transmit the fault indication signal to the communication module; the communication module can also be used to send the fault indication signal to the terminal. The status of each component of the smart city street light is detected and reported.

[0085] In this embodiment, the smart city streetlight displays the received video information through a display module and transmits the traffic signals to the terminal through an intelligent transportation component. This enables monitoring and management, data statistics, information query, parameter configuration, and user management.

[0086] Furthermore, this utility model embodiment also proposes an intelligent street light system. The intelligent street light system includes the intelligent urban street light described above.

[0087] Since the intelligent street light system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0088] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
