[0031] See also Figure 1 The present invention provides an NB-IoT wireless intelligent lighting control system. The NB-IoT wireless intelligent lighting control system includes a terminal lamp controller 10 based on the Internet of Things communication protocol. The terminal lamp controller 10 is used to control at least one of the following: the on / off, brightness, and color of the LED light module 2.

[0032] In this embodiment, the terminal lamp controller 10 is an external controller. That is, the terminal lamp controller 10 and the power module 150 for driving the LED light-emitting module 2 are electrically connected but independent components. The terminal lamp controller 10 can receive commands based on an IoT communication protocol and control the corresponding LED light-emitting module 2 to perform operations such as turning it on and off, dimming it, and changing its color according to these commands.

[0033] The terminal lamp controller 10 includes an Internet of Things communication module 101, a microprocessor 102, and a switch 112. Those skilled in the art will appreciate that the specific components, specifications, and parameters of the terminal lamp controller 10 can be selected as needed.

The GPS timing module is configured to update time information based on the location of the terminal lighting controller. The radar detection module is configured to generate activity information based on the sensed location and activity intensity of a person. The microprocessor adjusts the light brightness based on the time information and activity information.

[0035] By using a microprocessor to adjust light brightness based on time and activity information, intelligent lighting systems can significantly reduce energy consumption. For example, they can automatically adjust brightness based on actual needs, such as reducing brightness when no one is around or activity is low, thereby reducing energy consumption. Furthermore, they can provide a more comfortable lighting environment, reduce eye fatigue, and improve work efficiency and quality of life. Furthermore, their automated and intelligent nature means that the lighting system requires no human intervention and can work in conjunction with other smart home devices to provide a comprehensive automation solution.

[0036] Furthermore, by reducing lamp operating hours and avoiding wear and tear from frequent switching, the lamp's lifespan can be extended. Furthermore, by automatically turning on or enhancing lighting when needed, safety is improved, particularly in areas such as parking lots and corridors. Furthermore, by adjusting light brightness based on time and activity information, the microprocessor can reduce electricity bills and operating costs, while also reducing the frequency of lamp maintenance and replacement, further lowering costs.

[0037] Furthermore, the microprocessor adjusts light brightness based on the time and activity information, automatically adjusting indoor lighting to changes in ambient light to maintain a constant lighting level. Users can also customize lighting settings as needed, providing greater flexibility and customizability. Furthermore, proper brightness control can reduce light pollution in the surrounding environment, particularly in urban and residential areas. Finally, by saving energy and reducing carbon emissions, smart lighting systems support environmental protection and sustainable development goals.

[0070] The present invention can be applied to different scenarios and achieve better beneficial effects. First, it is used for energy-saving lighting of pedestrian and vehicle flows: when the environmental sensor senses that people and vehicles on the monitored road are moving within the range of the monitoring point, the environmental sensor sends an object active signal to the NB-IoT wireless network, and both the intelligent controller and the server can receive the signal; according to the manual pre-set function, the intelligent controller of the group automatically dims the light to bright, so that the monitoring location has high illumination, and the server displays the lighting status in real time; if the mobile energy-saving lighting function is manually turned off, the street lamp terminal controller and the server of the group will not act upon receiving the active signal; in the event of a disconnection of the gateway, IP network, or server, the automatic operation of the function is not affected, but the server cannot display the lighting status in real time; when the environmental sensor senses that people and vehicles on the monitored road are out of the range of the monitoring point, the environmental sensor sends an object active_over signal to the NB-IoT wireless network, and both the street lamp terminal controller and the server of the group can receive the signal; according to the manual pre-set function, the street lamp terminal controller of the group automatically dims the light to dark, or turns on the light at intervals, so that the monitoring location maintains the lowest illumination for energy saving, and the server displays the lighting status in real time; 2. Precise timed switching of lights in different seasons: The processor of the street light terminal controller calculates the daybreak and sunset time of the day based on the GPS date, local longitude and latitude, and local UTC time zone, and performs precise timed switching of lights. Compared with photosensitive switches that are easily polluted and fail, this is more practical and energy-saving. However, if the street light terminal controller is damaged, the photosensitive switch and ordinary timing control will take on the most basic control, minimizing the energy waste of lights on during the day. 3. Planned lighting control: Planned lighting is carried out according to the docking schedule of cargo ships at the port terminal, providing a manually defined calendar control schedule. The intelligent system can intelligently control the lighting and dimming within the scheduled time, and will not turn on the lights at night outside the schedule; 4. Automatic Fault Alarm: When a streetlight's output power deviates by 20%, or if the power output remains below 5W, the system identifies the streetlight as faulty. The system's number is displayed on the control computer, and location information is sent to maintenance personnel. These personnel can then use GPS navigation to locate the streetlight during the day and perform repairs. As a lighting supplier, fault information can also be viewed in the cloud, alerting users and providing replacement parts promptly. 5. Integrated control with the port system: The intelligent lighting control system provides control instructions to the port management system while performing intelligent self-control. It can achieve integrated control by receiving instruction intervention from the port management system. While performing intelligent lighting control, the instructions issued by the port management system take precedence over intelligent autonomous actions.

[0071] The present invention has achieved corresponding beneficial effects: intelligent control of LED lights improves energy saving rate by 55%, increases LED service life by 80%, and improves energy efficiency by 60%; dynamic sensing dimming technology reduces energy consumption of unmanned lights and reduces CO2 emissions by at least 50% compared with traditional control; calculates sunrise and sunset times by GPS latitude and longitude and season, and automatically adjusts lighting switching times globally without any settings; active fault alarm, fast GPS display positioning, convenient repair and maintenance, and reduces labor costs by 90%; mobile terminal monitoring and fault notification improve work execution efficiency by 70%; automatically detects haze, total solar eclipse, traffic, heavy rain, heavy fog and other environments for multiple linkage lighting control; uses encryption technology to ensure the security of the entire system control and the security of big data information; multi-level operation authority control, historical data query statistics, electricity metering trend analysis, and prepaid control system; when the network is disconnected, the built-in offline control strategy is automatically controlled, and the built-in large-capacity storage saves metering data for up to 60 days; it can be widely used in intelligent control of various scenarios such as highways, ordinary roads, and roads.
