[0002] As a symbol of civilized cities, streetlights have always been a core component of urban infrastructure. A brightly lit city at night is even seen as a sign of economic prosperity and social stability. With strong government support in recent years, my country has rapidly advanced the construction of smart cities, and smart streetlights are an important part of this development, expanding alongside the increasing investment in smart city initiatives.

[0003] In recent years, my country's urbanization rate has been continuously increasing, leading to a vigorous push for smart streetlights, a technology vital to the lives of the general public.

[0028] A monitoring terminal for monitoring the illumination status of streetlights includes a lithium-ion battery pack 1, a light intensity sensor 2, an NB-IoT rod antenna 3, a monitoring motherboard assembly 4, and a terminal housing 5. The lithium-ion battery pack 1, the monitoring motherboard assembly 4, and the light intensity sensor 2 are fixed inside the terminal housing 5. A stacked lens 6 and a filter 7 are fixedly connected to the terminal housing 5. The light intensity sensor 2 is located inside the filter 7. The NB-IoT rod antenna 3 is fixed outside the terminal housing 5. The monitoring motherboard assembly 4 includes a motherboard, a central processor 8, an RTC circuit chip 9, an NB-IoT communication module 10, a voltage regulation module 11, and a level conversion module 12. The central processor 8, the RTC circuit chip 9, the NB-IoT communication module 10, the voltage regulation module 11, and the level conversion module 12 are fixedly mounted on the motherboard.

[0029] The illuminance sensor 2 is used to sense the light after it has been filtered by the lens 6 and the filter 7. The lens 6 and the filter 7 can effectively prevent ultraviolet and infrared rays from entering the illuminance sensor 2, thereby improving the sensitivity of the illuminance sensor 2. The illuminance sensor 2 is electrically connected to the voltage regulation module 11 and the level conversion module 12 respectively.

[0030] The input terminal of the voltage regulating module 11 is electrically connected to the output terminal of the lithium-ion battery pack 1, and the output terminal of the voltage regulating module 11 is electrically connected to the central processor 8, the level conversion module 12, and the light intensity sensor 2. The lithium-ion battery pack 1 is used to provide power.

[0031] The input terminal of the NB-IoT communication module 10 is electrically connected to the output terminal of the central processor 8, and the output terminal of the NB-IoT communication module 10 is electrically connected to the NB-IoT rod antenna 3. The central processor 8 is used to perform preliminary analysis of the illumination information collected by the illuminance sensor 2, and transmit it to the NB-IoT rod antenna 3 through the NB-IoT communication module 10.

[0032] The NB-IoT rod antenna 3 modulates the illumination information and sends it to the base station and IoT service platform.

[0033] This invention effectively solves the problem of difficult monitoring of traditional streetlights through optimized design of the component structure and pin connections. The illuminance sensor 2 of this invention is used to sense the light emitted after being filtered by the lens 6 and the filter 7, forming a light signal. The illuminance sensor 2 transmits the light signal to the central processor 8 via the level conversion module 12. After processing the light information, the central processor 8 transmits the light information to the base station and the Internet of Things service platform via the NB-IoT communication module 10 and the NB-IoT rod antenna 3, thereby realizing intelligent monitoring of traditional streetlights with low cost, low energy consumption and high accuracy.

[0034] Work process:

[0035] The monitoring terminal uses the clock of the central processor 8 based on the RTC circuit chip 9 to determine whether the street light is ready to be turned on. After the street light is turned on, the monitoring terminal starts to periodically collect the illuminance of the street light, judge the status of the street light and report it to the Internet of Things service platform to facilitate the collection of relevant information about the smart street light. When it gets light, the street light is turned off and the monitoring terminal also enters a long-term sleep mode to reduce static power consumption and wait for the next collection cycle.

[0036] Optionally, in one possible implementation, the monitor motherboard assembly 4 further includes an RTC circuit chip 9 fixed on the motherboard. The RTC circuit chip 9 is a low-power real-time clock chip. The RTC circuit chip 9 is electrically connected to the central processor 8 and is used to provide a stable and continuous time reference for the monitoring terminal.

[0038] Optionally, in one possible implementation, the lithium-ion battery pack 1 includes a lithium battery and a power supply capacitor connected in parallel. The parallel-connected lithium battery and power supply capacitor can output a stable 3.6V standard voltage, providing a stable power supply.

[0039] Optionally, in one possible implementation, the illuminance sensor 2 has a detection range from 0 to 200,000 lumens, and the illuminance sensor 2 internally monitors the ambient illuminance of the terminal device through a photodiode and an ADC.

[0040] Optionally, in one possible implementation, both the voltage regulation module 11 and the level conversion module 12 are controlled by the central processor 8EN signal, thereby controlling whether the illuminance sensor 2 is enabled.
