Description

Technical Field

[0001] This utility model relates to the field of intelligent lighting technology, specifically to an intelligent lighting control system for high mast lights based on the Internet of Things. Background Technology

[0002] High mast lighting, as an important lighting facility, is widely used in ports, docks, airports, and many other locations due to its ability to provide large-area, high-intensity lighting effects. However, traditional high mast lighting control systems have gradually revealed a series of significant problems in practical applications.

[0003] In terms of lighting control methods, traditional systems mostly only have simple timed on / off functions. For example, in high-mast lighting in ports and docks, regardless of weather conditions (sunny, cloudy, rainy) or different time periods (such as late at night when there are few vehicles and pedestrians), the streetlights turn on and off according to preset fixed times, unable to automatically and flexibly adjust their brightness based on actual ambient light intensity, traffic flow, and work schedules. This results in streetlights maintaining high brightness even in areas with ample natural light or few pedestrians and vehicles, causing significant unnecessary energy consumption and failing to meet the urgent needs of modern society for energy conservation and emission reduction.

[0004] Streetlight maintenance also faces significant challenges. Traditional systems lack effective automatic monitoring and feedback mechanisms, making it impossible to promptly notify maintenance personnel when streetlights malfunction (such as bulb burnout or circuit failure). Problems can only be identified through regular manual inspections, which not only consumes substantial manpower, resources, and time, but also results in faulty streetlights being unable to illuminate properly during inspection intervals, severely impacting lighting service quality and posing safety hazards to work equipment, pedestrians, and vehicles traveling at night.

[0005] Furthermore, traditional high-mast lights lack effective communication methods and collaborative working capabilities. Each street light operates essentially independently, making group control and intelligent management impossible. For example, in the event of sudden emergencies (such as large-scale operations or emergency rescues that require temporary adjustments to lighting areas and brightness), it is impossible to quickly and uniformly coordinate the control of multiple street lights, failing to meet the complex and ever-changing lighting needs of modern ports and docks.

[0006] More importantly, from the perspective of communication reliability, many traditional lighting control systems use a single communication method. This single communication method is highly susceptible to interference in complex real-world environments (such as those with strong electromagnetic interference or building obstructions), leading to communication interruptions or signal transmission errors. This severely affects the stability and reliability of the lighting control system, and consequently, the normal operation of the entire lighting system.

[0007] In conclusion, in order to effectively improve the lighting management level of ports and wharves, achieve energy conservation, and reduce maintenance costs, it is urgent to develop a more intelligent, efficient, and reliable high-mast lighting control system to meet the needs of modern port and wharf development.

[0030] like Figure 1 As shown, this utility model proposes an intelligent lighting control system for high-mast lights based on the Internet of Things, including a main station server 1, a computer terminal 2, a mobile phone terminal 3, a 4G / 5G base station 4, a communication conversion base station 5, and N dual-mode high-mast light lines 6. The N dual-mode high-mast light lines 6 are interconnected, and the N dual-mode high-mast light lines 6 are wirelessly connected to the communication conversion base station 5. The communication conversion base station 5 is wirelessly connected to the 4G / 5G base station 4, the 4G / 5G base station 4 is wirelessly connected to the main station server 1, and the main station server 1 is connected to the computer terminal 2 and the mobile phone terminal 3 via network communication; where N is a positive integer greater than 3.

[0031] like Figure 2 As shown, the communication conversion base station 5 includes a microprocessor 51 and a main HRF communication module 52, a 4G / 5G communication module 53, and a power supply module 54 electrically connected to the microprocessor 51. The main function of the communication conversion base station 5 is to conduct HRF wireless communication with each dual-mode high-mast lighting line, realize data acquisition and monitoring, and convert it into 4G / 5G communication for uploading to the main station server.

[0032] like Figure 3 As shown, any one of the N dual-mode high-mast light lines 6 includes a microcontroller 61 and a slave HRF communication module 62, an HPLC communication module 63, a power conversion module 65, a street light brightness adjustment module 67, and a positioning module 69 electrically connected to the microcontroller 61. The slave HRF communication module 62 is wirelessly connected to the main HRF communication module 52 of the communication conversion base station 5. The power conversion module 65 is electrically connected to the mains power supply line 64. The slave HRF communication module 62, the HPLC communication module 63, and the mains power supply line 64 are connected to the Mth dual-mode high-mast light line 6. The mains power supply line 64 is electrically connected to the power conversion module 65. The power conversion module 65 is electrically connected to the street light brightness adjustment module 67. The street light brightness adjustment module 67 is electrically connected to the high-mast light power supply line 68. Here, M is a positive integer greater than 3, and M∈N.

[0033] Specifically, the HRF communication module 62 is wirelessly connected to the Mth dual-mode high-mast light line 6, the HPLC communication module 63 is wiredly connected to the Mth dual-mode high-mast light line 6, and the mains power supply line 64 is electrically connected to the Mth dual-mode high-mast light line 6. Combined with... Figure 4 As shown, each street light line has at least one microcontroller-based control node. The circles in the diagram represent control nodes, each capable of HRF, HPLC, and dual-mode communication. The remaining half represents the streetlights. The shaded half of the control node represents High-Speed ​​Radio Frequency (HRF), and the hollow half represents High-Speed ​​Power Line Communication (HPLC). Each line communicates with adjacent lines via HRF and / or HPLC, depending on the site conditions. HPLC directly transmits streetlight control and monitoring signals via power line communication technology. It connects to the mains power supply or HPLC module of adjacent streetlight lines and complements it through HRF wireless communication technology, ensuring communication reliability and flexibility.

[0034] In this embodiment, the mains power line 64 is electrically connected to the distributed power source 66, which includes, but is not limited to, wind power, solar power, charging pile power, biomass power, and tidal power. These renewable energy sources can be used to complement the mains power line nearby. During connection, an inverter, battery, and electrical transfer switch are used. The inverter is used to convert renewable energy into AC mains power, the battery is used for energy storage, and the electrical transfer switch is used for power switching.

[0035] Multiple LED lights are connected in parallel on the high mast light power supply line 68.

[0037] The microprocessor 51 is an ARM processor or a DSP processor chip. Since the communication conversion base station 5 is the core link for monitoring data transmission, it uses a high-performance processor device. There are no specific restrictions on the chip model; it is determined based on the actual configuration.

[0038] The microcontroller 61 is a single-chip microcomputer. The control node of the street light circuit is mainly responsible for controlling the brightness and on / off state of the street lights according to control signals. A single-chip microcomputer can meet this requirement, and there is no specific limitation on its model, such as the STM32 series microcontroller. The microcontroller 61 can be expanded to connect to lighting environment sensing and power line sensing components, which are not shown here.

[0039] like Figure 5As shown, the power conversion module 65 is a DC regulated power supply that outputs multiple DC voltages, such as a multi-output switching power supply, which can output 12V and 24V DC power.

[0040] The street light brightness adjustment module 67 is a PWM dimming circuit. Its basic principle is to use a microcontroller (single-chip microcomputer) to output a PWM control signal, and control the current conduction of the switching device (such as MOSEFT) according to the PWM duty cycle, thereby controlling the brightness of the lamp. In extreme cases, it can control the lamp to turn on and off.

[0041] The working principle of this utility model is as follows:

[0042] like Figure 1 As shown, street light monitoring data collected from multiple dual-mode high-mast light lines are transmitted to the communication conversion base station via HRF wireless communication (HRF wireless communication technology can transmit over distances of hundreds of meters or even further in an ideal open environment). The communication conversion base station then uploads the monitored data to the main station server via 4G / 5G communication, enabling monitoring of the entire area.

[0043] like Figure 3 The diagram shown is a schematic block diagram of the control node of the dual-mode high-mast light line 6. It enables control via HRF, HPLC, and dual-mode communication, as well as brightness and on / off control of the streetlight line through the streetlight brightness adjustment module 67. Combined with... Figure 4 As shown, each street light line has at least one microcontroller-based control node. The circles in the diagram represent control nodes, each capable of HRF, HPLC, and dual-mode communication. The remaining nodes represent streetlights. Each line communicates with adjacent lines via HRF and / or HPLC, depending on the site conditions. HPLC directly transmits streetlight control and monitoring signals via power line carrier technology. It connects to the mains power supply or HPLC module of adjacent streetlight lines and complements this connection through HRF wireless communication technology, ensuring communication reliability and flexibility.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
