[0019] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0020] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed at will, and the component layout may also be more complex.

[0021] Some exemplary embodiments of the present invention are described for the purpose of illustration. It should be understood that the present invention may be implemented in other ways not specifically shown in the drawings.

[0022] like Figure 1 As shown, in a specific embodiment, a multi-port urban lighting control terminal is provided, which includes a main control module, a fault detection module, a positioning module, a communication module, a data acquisition module, a dimming module, a switch control circuit, and additional interfaces. In this embodiment, the main control module uses an STM32 series ARM processor.

[0023] The fault detection module includes an overvoltage detection circuit, a current detection circuit, an undervoltage detection circuit, an overcurrent detection circuit, a lamp pole tilt detection module, a leakage protection circuit, and a fault judgment circuit. It promptly detects whether the current lighting device has overvoltage, undervoltage, overcurrent, lamp pole tilt, leakage, light source damage, accidental light out, accidental light on, and light off faults, and generates fault information. The main control module generates an alarm signal based on the fault information to realize real-time monitoring of the operating status of the lighting device. When a lamp pole tilt fault occurs, the initial tilt angle can be adjusted, and the leakage protection can display the leakage value.

[0024] Since the position of each lamp pole on site is different and the street conditions are also different, when the lamp pole tilts, it will not only affect the lighting effect, but may also affect the safety of the lighting. Therefore, when installing the urban lighting multi-port lighting control terminal, it is necessary to reset its unique original angle value and angle change threshold according to the horizontal position of each lamp pole. When the street light pole tilts due to external force, the lamp pole tilt detection module will detect the tilt angle and compare it with the initial set angle. When the change angle exceeds the set threshold, it indicates that the lamp pole is at risk of tipping over. An alarm message will be generated and sent to the management platform to notify the operation and maintenance personnel to handle it.

[0025] The voltage detection circuit and the current detection circuit are used to detect the current voltage and current values ​​of the LED lamp. The undervoltage detection circuit and the overcurrent detection circuit compare the detected voltage and current values ​​with the rated values. When it is determined that an undervoltage or overcurrent fault occurs, the main control chip performs a power-off protection operation and generates an alarm signal to drive the alarm to sound an alarm. The alarm method can adopt multiple methods such as multimedia, voice, message push and short message. After receiving the alarm, the maintenance personnel can arrive at the accident site in a timely and accurate manner according to the alarm information to handle the fault.

[0026] The positioning module uses the Beidou positioning system (based on GIS mapping) and is capable of background statistics. When a fault occurs, it can directly locate the LED lamp's location and send the coordinates to a mobile app. This feature eliminates the need for maintenance personnel and patrol vehicles to conduct on-site inspections. The faulty lamp pole can be directly located, and the navigation system can be used to reach the location for direct repair. This significantly saves manpower and material resources. It also features single-lamp extinguishing location and alarms for multiple consecutively extinguished street lamps connected in series.

[0027] The dimming module is used to adjust the brightness of the lighting device according to needs. The circuit structure of the dimming module is as follows: Figure 4 The PWM dimming circuit shown uses pulse width modulation dimming to perform dimming operations. During operation, the main control circuit continuously changes the duty cycle of the current or voltage to achieve PWM dimming. In this embodiment, PWM dimming can simulate a dimming range of 0-100%, and has high dimming accuracy, good reliability, and low cost, and can be widely used.

[0028] The communication module utilizes Cat.1 wireless communication technology, offering fast communication speeds, capable of achieving millisecond resolution, long transmission distances, and real-time data collection without lag. This delivers excellent real-time performance, high reliability, and enhanced communication efficiency. Direct communication with the system platform eliminates the need for an external gateway, resulting in higher communication efficiency and lower communication failure rates. This allows for a 99% device online rate and a response time of less than one second, enabling real-time command and alarm uploads. Wireless communication utilizes the internationally advanced AES128 encryption algorithm to effectively safeguard data security. The management platform utilizes server clustering and distributed deployment technology to maximize service reliability and security.

[0029] The switch control circuit controls the switch of the lighting device according to the switch signal sent by the main control module, so as to control the switch of the LED lamp to achieve the purpose of lighting on demand.

[0030] The data acquisition module includes a voltage acquisition circuit, a current acquisition circuit, a power acquisition circuit, a power factor acquisition circuit, an electric energy acquisition circuit and a line parameter acquisition circuit, which are used to collect various power parameters of LED lamps, including voltage, current, power, power factor and electric energy.

[0031] In the existing technology, the monitoring of lighting devices is usually limited to the lighting devices themselves, but the health status of the lighting device lines is also an important factor that cannot be ignored. The control terminal in the present invention includes a line alarm. The main control module collects data through the line and compares it with the theoretical data. When the collected data changes, based on the cable laying time, laying environment, laying depth and its own life, after multiple comparisons of the data, it is found that the changes continue to increase. It is judged that the health status of the cable has declined and requires special attention, and maintenance personnel are sent to the site to conduct on-site investigation and troubleshooting.

[0032] The line parameters include the leakage current value on the line. By collecting the leakage current of each single lamp control terminal on the entire line, the fault judgment circuit is used to analyze the difference between the real-time leakage current and the initial safe leakage current. If it exceeds the safety range, it is determined that the cable is damaged or aged, and there is an unsafe factor. The fault judgment result is sent to the main control chip, and the data is transmitted back to the management platform. After big data and intelligent calculations, the main control chip sends an alarm signal to notify maintenance personnel to deal with it in time, and at the same time turns on the leakage protection circuit for emergency leakage protection.

[0033] Different lighting scenarios require different lighting requirements. To meet these diverse lighting needs and adapt to diverse application scenarios, the main control module is compatible with other devices through additional interfaces. These interfaces connect the main control module to the environmental monitoring module, illuminance module, vehicle flow detection module, and pedestrian flow detection module. These additional interfaces enable one-stop access to the multi-port urban lighting control terminal for numerous devices, simplifying project networking while significantly improving the stability of device connections and communications. The main control module collects data on environmental parameters, device status, traffic flow, and pedestrian flow. This data is integrated and processed through cloud computing and big data analytics, providing decision makers with accurate information and insights, and providing data support for the setup and layout of lighting fixtures.

[0034] In a specific embodiment, the lighting device is a street lamp, and the structural diagram of the urban lighting multi-port lighting control terminal when installed on the street lamp is as follows: Figure 2 The multi-port lighting control terminal for urban lighting can save energy based on intelligent algorithms, and can also be set to save energy according to user needs by turning on alternate lights, turning off lights on one side, or even turning off all lights.

[0035] The utility model's urban lighting multi-port light control terminal is installed inside LED lamps, supports quick installation, is simple and easy to operate, and only needs to be connected in series within the circuit; it has a large information processing capacity, provides rich and powerful functional interfaces, enhances product compatibility, and can operate normally and stably in harsh environments of -40℃-+85℃, and is resistant to erosion by rain, snow and fog.

[0036] This embodiment uses a proprietary intelligent algorithm, combines different usage scenarios and lighting conditions, and utilizes external sensors, including weather, sunlight conditions, vehicle flow, and pedestrian flow, for real-time monitoring. It adjusts different power levels to ensure that the illumination meets the requirements of the "Urban Road Lighting Design Standard" CJJ45-2015, thereby maximizing energy saving. Compared with traditional time-sharing dimming energy-saving methods, LED lamps can be deeply energy-save under low traffic flow conditions in the second half of the night, with an energy saving rate of more than 50%, truly ensuring that every beam of light is projected according to demand.

[0037] like Figure 3 As shown, in a specific embodiment, a lighting control system is provided, including a remote management platform, a mobile terminal and several city lighting multi-port light control terminals. The city lighting multi-port light control terminal is the city lighting multi-port light control terminal described in the above embodiment.

[0038] In this embodiment, the single-lamp control system based on wireless ad hoc networking technology can achieve an online rate of over 99% for each lamp controller. This means that after a command is issued from the remote management platform (data downlink), 99% or more of the lamp controllers in the group respond within 1 second. Furthermore, after a query command is issued from the public lighting digital information management cloud platform (data uplink), 99% or more of the lamp controllers in the group report data to the management platform within 5 seconds. This ensures real-time remote control of individual lamps and real-time telemetry of data, fully ensuring consistent and uniform control on the road and timely and accurate reporting of lamp faults.

[0039] If any link in the control system fails (server failure, communication failure, centralized controller failure, or individual lamp controller failure), local strategies can still be implemented to ensure that road lighting facilities can be controlled and managed according to traditional loop control methods, without affecting their basic road lighting functions. Traditional time-of-day dimming cannot fully guarantee that road lighting illumination meets national standards and poses certain safety risks. For example, drivers are prone to fatigue and inattention in the second half of the night, and traffic is generally faster in the latter half of the night when there is less traffic. In fact, in such operating conditions, the illumination of road lighting should be fully guaranteed to ensure the driver's visual observation effect and avoid accidents. In other words, the lighting control system of the present invention takes "safety" as its primary consideration and fully considers the safety of each application link.

[0040] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
