Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things lighting, and in particular to a lighting power supply control method and system based on the Internet of Things. Background Art

[0002] With the rapid development of science and technology, the process of intelligent and digital cities is accelerating. Intelligent and digital transformation and upgrades have become an inevitable trend in urban roads, industrial parks, and parks. However, these upgrades currently face numerous challenges. In traditional pole-mounted communications, the lack of unified planning and standards has led to the disorganized installation of various communication devices. Different types of poles may be equipped with different communication modules, resulting in severe signal interference and difficulties in ensuring communication quality. Furthermore, wiring practices are not standardized. The wiring layout is not rationally designed, resulting in complex and tangled wiring in some areas, which not only affects the aesthetics but also increases maintenance difficulties.

[0003] In the lighting sector, traditional lighting solutions use typical conventional drivers for AC-DC conversion. While this stand-alone lighting solution may have met basic lighting needs in the past, its drawbacks are becoming increasingly apparent with the development of IoT and digital technologies. For one thing, conventional drivers are limited in functionality, making them incapable of remote control, remote debugging, and intelligent dimming. In today's era of energy conservation and environmental protection, the inability to adjust lighting brightness and duration based on actual needs results in energy waste. Furthermore, stand-alone lighting solutions struggle to integrate with other smart devices, hindering their integration into the overall smart city architecture.

[0020] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the accompanying drawings: A lighting power control system based on the Internet of Things, such as Figure 1 As shown, it includes a control terminal, a debugging terminal, a magic box device and several lighting devices.

[0022] The control terminal is wirelessly connected to the magic box device.

[0023] The debugging terminal is wirelessly connected to the magic box device.

[0024] The magic box device is connected to the plurality of lighting devices via Bluetooth 5.4.

[0025] The control terminal transmits control instructions to the plurality of lighting devices through the magic box device.

[0026] The debugging terminal transmits debugging instructions to the plurality of lighting devices through the magic box device.

[0027] The plurality of lighting devices feed back abnormal data to the control terminal through the magic box device.

[0028] It should be noted that the wireless connection includes WiFi and mobile data network.

[0029] It should be noted that the control instruction includes control information of a single or multiple lighting devices.

[0030] It should be noted that the debugging instruction includes debugging information of a single or multiple lighting devices.

[0031] It should be noted that the abnormal data includes brightness abnormal data, flicker frequency abnormal data and temperature abnormal data.

[0032] Understandably, in a large industrial park's lighting system, the control terminal is a high-performance server located in the park's management center, equipped with specialized lighting power control software. This allows staff to remotely monitor and manage the entire park's lighting equipment. The commissioning terminal, a tablet computer carried by the park's electrical engineers, facilitates on-site commissioning.

[0033] As expected, Magic Box devices are installed at key locations throughout the campus to ensure stable wireless connections with control and debugging terminals. These wireless connections utilize high-speed Wi-Fi or mobile data networks to quickly transmit large amounts of data. Furthermore, the Magic Box devices connect to the various lighting devices via Bluetooth 5.4, ensuring low power consumption and stable communication.

[0034] It's understandable that during daily operation, the control terminal can transmit control commands to the lighting equipment through the Magic Box device based on different time and weather conditions. For example, during sunny daytime, the control terminal can send commands to reduce the brightness of the lighting equipment or turn off the lighting in certain areas to save energy. At night or on cloudy days, the control terminal can increase the brightness of the lighting equipment to ensure safety and visibility in the park.

[0035] It's understandable that when a lighting device experiences a malfunction or anomaly, it will send abnormal data back to the control terminal via the Magic Box device. For example, if a lighting device's brightness suddenly decreases or flickers, it will transmit the device number, abnormal status, and related parameters to the Magic Box device via Bluetooth 5.4. The Magic Box device then sends this abnormal data to the control terminal via WiFi.

[0036] As you can understand, after receiving abnormal data, the control terminal analyzes it, generates debugging parameters, and then sends these parameters to the debugging terminal. Based on the information on the debugging terminal, the debugging personnel can quickly locate the problem and send debugging instructions to the lighting equipment through the debugging terminal and the magic box device. For example, if the power module of a lighting device fails, the debugging personnel can send a command through the debugging terminal to temporarily shut down the lighting device and then return to the site for repair or replacement of the power module.

[0037] It is understandable that through this IoT-based lighting power control system, large industrial parks can achieve efficient and intelligent lighting management, improve energy utilization efficiency, reduce maintenance costs, and at the same time ensure the lighting quality and safety of the park.

[0038] like Figure 2 As shown, the lighting device further includes: a digital processing module and a power electronics module.

[0039] The digital processing module includes: a main control unit, a sensing unit, a communication unit, a voltage stabilization and filtering unit, an auxiliary source voltage transformation unit, an output power metering unit, a temperature acquisition unit and an RTC unit.

[0040] The main control unit is connected to the sensing unit, the communication unit, the voltage stabilizing and filtering unit, the auxiliary source voltage transformation unit, the output power metering unit, the temperature acquisition unit and the RTC unit.

[0041] The communication unit is wirelessly connected to the control terminal, the debugging terminal and the magic box device.

[0042] The main control unit is the core control component of the digital processing module, responsible for coordinating and managing the work of other units, and is responsible for various tasks such as data processing, task scheduling, and environmental perception. It receives information from the sensing unit and communication unit, analyzes and processes it, and then issues corresponding control commands to achieve intelligent control of lighting equipment, such as adjusting brightness and responding to commands from the control terminal.

[0043] The sensing unit is primarily used to detect the operating status of the lighting equipment and surrounding environmental parameters. It can communicate with external sensors wirelessly or wiredly to illuminate or adjust the lighting brightness when a vehicle or person approaches. It can also monitor electrical parameters such as current, voltage, and power in the lighting equipment to promptly detect abnormalities and provide feedback to the main control unit. It may also include an ambient light sensor to detect ambient brightness and provide a basis for automatic brightness adjustment.

[0044] It should be noted that according to the linear adjustment principle, the relationship between ambient light brightness and lighting equipment brightness adjustment formula is:

[0045] Among them, L env is the ambient light brightness detected by the ambient light sensor (unit: lux), L0 is the initial brightness of the lighting device (unit: lumen, lm), L adjust is the adjusted brightness.

[0046] The communication unit includes wired or wireless communication modules such as HPLC, 4Gcat.1, BT (2.4G mesh), Wi-Sun, OpenThread, LoraWAN, and RS485. These modules enable data exchange with the IoT platform. For example, Bluetooth 5.4 can be used to connect to the Magic Box device, enabling data exchange with the control terminal and debugging terminal. Control commands are received and transmitted to the main control unit, while also feeding back lighting device status information and abnormal data to the control terminal.

[0047] The voltage stabilization and filtering unit ensures stable and pure power input to the lighting device. It stabilizes and filters the voltage after DC rectification, providing a stable power source for the entire digital signal processing and communication unit. It eliminates clutter and interference in the power supply, providing a stable voltage to other units and lighting components, preventing voltage fluctuations from affecting the normal operation of the lighting device and extending the device's service life.

[0048] The auxiliary power transformer unit is used for AC voltage transformation and AC-DC rectification, providing appropriate auxiliary power for specific circuits or low-power components in the lighting device. For example, it provides power at different voltage levels required for sensors and communication units to ensure their normal operation.

[0049] The output power metering unit primarily collects and measures output voltage, current, and power, monitoring the lighting device's output power in real time and feeding this data back to the main control unit. This helps the control terminal understand the lighting device's energy consumption for energy management and optimization. Furthermore, in the event of an abnormality, power fluctuations can be used to determine whether the device is faulty.

[0050] The temperature acquisition unit monitors the operating temperature of the lighting equipment. It uses NTC technology to obtain the temperature value of the highest power supply point, and then converts it into real-time temperature through analog-to-digital conversion. Excessive temperatures can affect the performance and lifespan of the equipment, and even cause safety issues. The temperature acquisition unit transmits this temperature data to the main control unit, which can then take appropriate measures based on the temperature, such as reducing power or activating heat dissipation devices.

[0051] The RTC unit is responsible for the main control clock and timing, as well as for time calibration, providing accurate time information for lighting devices. It can be used to control lighting functions such as on / off and brightness adjustment. For example, it can automatically turn lights on or off during specific time periods or adjust brightness based on different time points, achieving more intelligent lighting control.

[0052] The power electronic module includes: a PWM control unit, a power conversion unit, an anti-reverse connection protection unit, an ESD unit, an EMI unit, an AC transformer unit, a rectifier and filter unit, an overvoltage and undervoltage protection unit, a PFC active compensation unit, a constant current and constant voltage output unit, a voltage feedback loop unit, a sampling unit, a short circuit protection unit, an overvoltage protection unit, a current limiting protection unit, and a load.

[0053] The PWM control unit is connected to the overvoltage and undervoltage protection unit, the overvoltage protection unit, the current limiting protection unit, the voltage feedback loop unit, the short circuit protection unit, the power conversion unit and the main control unit.

[0054] The power conversion unit is connected to the temperature acquisition unit, the rectification and filtering unit and the constant current and constant voltage output.

[0055] The constant current and constant voltage output unit is connected to the output power metering unit, the short circuit protection unit, the sampling unit, the overvoltage protection unit, the current limiting protection unit and the load.

[0056] The AC transformation unit is connected to the auxiliary source transformation unit, the EMI unit and the rectification and filtering unit.

[0057] The ESD unit is connected to the reverse connection protection unit and the EMI unit.

[0058] The overvoltage and undervoltage protection unit is connected to the rectification and filtering unit and the PFC compensation unit.

[0059] The sampling unit is connected to the voltage feedback loop unit.

[0060] The rectification and filtering unit is connected to the PFC compensation unit.

[0061] The PWM controller collects various output information and feeds it back to the power conversion unit to ensure constant output power. It then generates a pulse-width modulation signal to control the power conversion unit's operating state. By adjusting the pulse width duty cycle, the output voltage and current can be precisely controlled, enabling dimming of the lighting device and efficient power conversion.

[0062] It should be noted that the brightness adjustment formula of the PWM control unit is:

[0063] Where D is the duty cycle of the PWM signal (0≤D1), V in is the input voltage, V out The output voltage is the voltage. According to the relationship between the brightness of the lighting device and the supply voltage (assuming that the brightness is proportional to the voltage), the brightness of the lighting device can be adjusted by adjusting the duty cycle D.

[0064] The power conversion unit utilizes the fast characteristics of MOSFETs to achieve power conversion. Specifically, it performs power conversion based on signals from the PWM controller unit. It converts input electrical energy into a specific voltage and current suitable for the lighting device, providing a stable power supply for the lighting device.

[0065] The reverse polarity protection unit is used to protect the input side of the neutral and live wires from reverse polarity, preventing the lighting device from being connected with reverse polarity. If the positive and negative polarity of the power supply are reversed, the unit blocks the flow of current, protecting the lighting device and other components in the power electronics module from damage.

[0066] The ESD unit is a lightning protection unit designed to handle abnormally high voltages and protect lighting equipment from electrostatic discharge. During equipment operation, transportation, or when exposed to external static electricity, the ESD unit quickly discharges static electricity to the ground, preventing damage to sensitive electronic components.

[0067] The EMI unit reduces electromagnetic interference generated by lighting equipment and prevents external electromagnetic interference from affecting the normal operation of the lighting equipment. Through filtering, shielding and other measures, it ensures that the lighting equipment complies with electromagnetic compatibility standards.

[0068] The AC transformer unit can be understood as a transformer that steps up or down the voltage of the AC input. If the input power is AC, the AC transformer unit will transform it to meet the requirements of the subsequent circuits. It can convert high-voltage AC into a suitable low-voltage AC.

[0069] The rectifier and filter unit converts AC to DC through a rectifier bridge, converting AC power into DC power and filtering the DC power to remove ripple and noise in the DC power, providing a smooth and stable DC power supply to the lighting equipment.

[0070] The overvoltage and undervoltage protection unit monitors the voltage of the input power supply. When the voltage exceeds the set upper limit (overvoltage) or is lower than the set lower limit (undervoltage), the unit will cut off the power input to protect the lighting equipment from damage caused by excessively high or low voltage.

[0071] The PFC active compensation unit, which can be understood as active power factor correction, ensures a power factor greater than 0.95, improving the lighting device's power factor and reducing harmonic pollution on the power grid. By shaping and phase-adjusting the input current, the lighting device's input power factor approaches unity, improving energy efficiency.

[0072] The constant current and constant voltage output unit automatically adapts to the selected output mode, ensuring constant current and voltage output to the lighting device. This unit maintains a stable output regardless of load changes or input power fluctuations, ensuring consistent brightness and performance.

[0073] It should be noted that in constant current mode, the formula for the actual output current is:

[0074] Among them, I out is the actual output current, T is the temperature, T0 is the reference temperature, K I (T) is the current temperature coefficient (unit: A / °C), and I0 is the initial setting current.

[0075] It should be noted that when the load has complex dynamic characteristics, in order to maintain constant current, the output voltage V out The formula is:

[0076] Among them, the load resistance R L Changes exponentially with time t, that is, R L (t) = R0e -at , where R0 is the initial load resistance, a is the attenuation coefficient, τ is the response time, I set is the preset current.

[0077] It should be noted that in constant voltage mode, the actual output current I out The formula is:

[0078] Among them, Iset is the preset current, A i is the amplitude of the i-th frequency component, ω i is the angular frequency, is the phase, K Vn is the adjustment factor.

[0079] The voltage feedback loop unit feeds back the output voltage to the control system (such as the PWM controller unit). By comparing the actual output voltage with the set target voltage, the control signal is adjusted to achieve precise control of the output voltage.

[0080] The sampling unit is used to collect output power, including sampling core parameters such as voltage, current, and temperature in the power electronics module. The sampled data is provided to the control system for monitoring and control. For example, it is used to detect whether the output current exceeds the current limit value to trigger the current limiting protection unit.

[0081] The short-circuit protection unit quickly cuts off the power output when a short-circuit fault occurs in the lighting device to prevent excessive current from damaging the device and causing a safety accident.

[0082] The overvoltage protection unit is different from the overvoltage protection in the overvoltage and undervoltage protection unit. This unit mainly protects against overvoltage conditions at the output end. When the output voltage rises abnormally, measures are taken immediately to protect the lighting equipment from damage caused by excessive voltage.

[0083] The current limiting protection unit limits the output current. When the output current exceeds the set current limit, the unit adjusts the circuit operating state to reduce the output current, protecting the lighting equipment and power electronic module from overcurrent damage.

[0084] A lighting power control method based on the Internet of Things, see Figure 3 As shown, the control method comprises the following steps: Step S100: The control terminal transmits control instructions to a plurality of lighting devices through the magic box device.

[0085] In this step, the control terminal is connected to the magic box device via a wireless connection; the magic box is wirelessly connected to the plurality of lighting devices via Bluetooth 5.4.

[0086] It should be noted that the wireless connection includes WiFi and mobile data network.

[0087] It is understandable that if Figure 4As shown, the control terminal sends the data1 data control instruction to the magic box device wirelessly. After the magic box device obtains the data1 data control instruction, it analyzes it and sends the control instruction to the corresponding lighting device, specifically including: sending it to a single lighting device or to multiple lighting devices.

[0088] It should be noted that the control instruction includes control information of a single or multiple lighting devices.

[0089] It is understandable that if Figure 4 As shown, the control device sends a control instruction information that only controls the first lighting device. After the magic box device obtains the control instruction information, it analyzes that the instruction is only for the first lighting device. Then, the magic box device can send the control instruction information to the first lighting device.

[0090] It should be noted that the control information consists of 16-bit binary code.

[0091] It's understandable that the Magic Box can identify the specific lighting device to which the control command is sent based on the packet header information of the control command. For example, taking a 16-bit binary packet header data code as an example, the packet header code of the first lighting device is 0000000000000001, and the packet header code of the second lighting device is 0000000000000010. Similarly, the common command for the first and second lighting devices is 0000000100000000, etc.

[0092] It is understandable that, for example, in an industrial park's lighting system, the control terminal could be a central server installed with specialized lighting management software. Workers use the control terminal to set control instructions such as the brightness and on-time of different lighting devices in different areas.

[0093] As you can see, the Magic Box device acts as a communication hub, receiving commands from the control terminal and distributing them wirelessly via Bluetooth 5.4 to lighting devices located throughout the commercial center. For example, in an area with less traffic during the day, the control terminal sends a command to the Magic Box device to adjust the lighting brightness in that area to 50% to save energy.

[0094] In step S200, the debugging terminal transmits debugging instructions to a plurality of lighting devices through the magic box device.

[0095] In this step, the debugging terminal is connected to the magic box device via a wireless connection; the magic box is wirelessly connected to the plurality of lighting devices via Bluetooth 5.4.

[0096] It should be noted that the wireless connection includes WiFi and mobile data network.

[0097] It is understandable that if Figure 4 As shown, the debugging terminal sends the data2 data control instruction to the magic box device wirelessly. After the magic box device obtains the data2 data debugging instruction, it analyzes it and sends the control instruction to the corresponding lighting device, specifically including: sending it to a single lighting device or to multiple lighting devices.

[0098] It should be noted that the debugging instruction includes debugging information of a single or multiple lighting devices.

[0099] It is understandable that if Figure 4 As shown, the debugging terminal sends a debugging instruction information for debugging only the first lighting device. After the magic box device obtains the debugging instruction information, it analyzes that the instruction is only for the first lighting device. Then, the magic box device can send the debugging instruction information to the first lighting device.

[0100] It should be noted that the debugging information consists of 16-bit binary code.

[0101] It's understandable that the Magic Box can identify the specific lighting device to which the debug command is sent based on the debug command's header information. For example, using a 16-bit binary header data code, the header code for the first lighting device is 1000000000000001, and the header code for the second lighting device is 1000000000000010. Similarly, the common command for the first and second lighting devices is 1000000100000000, etc.

[0102] It's understandable that when a lighting system experiences a malfunction during post-installation commissioning or daily operation, commissioning personnel use a debugging terminal (which can be a portable tablet) to send specific test commands to the lighting device through the Magic Box device. For example, they might send a command to cause a specific lighting device to flash three times to confirm its location and operating status. If the lighting device detects an abnormality, such as abnormal brightness or flashing frequency, it will send abnormal parameter data containing the device number, abnormality type, and specific parameter values back to the control terminal through the Magic Box device. For example, if a lighting device reports that its actual brightness is only 30% of its set brightness, this could be due to lamp aging or a power failure.

[0103] In step S300, the lighting device feeds back abnormal data to the control terminal through the magic box device.

[0104] In this step, the abnormal data includes brightness abnormal data, flicker frequency abnormal data and temperature abnormal data.

[0105] It is understandable that if Figure 4As shown, the second lighting device sends the data3 abnormal data generated by itself to the magic box device via Bluetooth 5.4 wirelessly. After the magic box device obtains the data3 abnormal data, it analyzes it and sends the data3 abnormal data to the control terminal.

[0106] It should be noted that the abnormal data consists of 16-bit binary code.

[0107] It's understandable that the Magic Box can identify the target (control terminal) to which the abnormal data is being sent based on the packet header information. Taking a 16-bit binary packet header data code as an example, the first two bits are the abnormal data flags. For example, 11xx00000000xxxx indicates that the Magic Box device can identify abnormal data x for the xth lighting device. Another example is 1101000000000001, indicating abnormal brightness data for the first lighting device; 1110000000000001, indicating abnormal flicker frequency data for the first lighting device; and 1111000000000001, indicating abnormal temperature data for the first lighting device.

[0108] Understandably, during daily operation, if a lighting device malfunctions, it will report abnormal parameter data to the control terminal through the magic box device. For example, if a lighting device flickers frequently, it will report abnormal parameter data such as the device number, flicker frequency, and current voltage to the control terminal. The control terminal can use this data to determine the general direction of the problem.

[0109] Step S400: The control terminal analyzes the abnormal data, generates debugging parameter data, and sends the data to the debugging terminal.

[0110] In this step, the debugging parameter data includes brightness parameter data, flicker frequency parameter data and temperature parameter data.

[0111] It is understandable that if Figure 4 As shown, the magic box device sends the abnormal data data3 to the control terminal via wireless. After the control terminal obtains the abnormal data data3, it analyzes it, forms debugging parameter data, and sends the debugging parameter data to the debugging terminal.

[0112] It should be noted that the debugging parameter data is composed of 16-bit binary code.

[0113] It is understandable that the control terminal can identify the type of abnormal data through the header information of the abnormal data and form the corresponding debugging parameter data. Taking the 16-bit binary header data code as an example, the first 2 bits are the debugging parameter data flag bits, such as: 10xx00000000xxxx, the debugging terminal, magic box device and lighting device can identify the x debugging parameter data of the x-th lighting device. For example: 1001000000000001, the debugging terminal, magic box device and lighting device can identify the brightness parameter data of the first lighting device; 1110000000000001, the debugging terminal, magic box device and lighting device can identify the flicker frequency parameter data of the first lighting device; 1111000000000001, the debugging terminal, magic box device and lighting device can identify the temperature parameter data of the first lighting device.

[0114] In this step, the control terminal receives abnormal data from lighting devices and analyzes it using its built-in data analysis algorithms and empirical database. If multiple lighting devices in the same area experience a gradual decrease in brightness, this could be due to aging power lines in that area. Based on the analysis results, the control terminal generates debugging parameters, such as checking the lighting devices' AC transformers, power converters, and constant current and voltage output units, and sends these parameters to the debugging terminal.

[0115] Step S500: The debugging terminal executes a specific debugging instruction operation according to the debugging parameter data, and sends the debugging instruction to the lighting device through the magic box device.

[0116] In this step, after receiving the debugging parameters sent by the control terminal on the debugging terminal, the debugging personnel will perform specific debugging operations based on the parameters. For example, if the debugging parameters require replacing the driver module of a lighting device, the debugging personnel will bring the corresponding module to the site for replacement. After the replacement is complete, the debugging terminal sends a test command to the lighting device through the magic box device to confirm whether the device has resumed normal operation. If the device is functioning normally, the debugging personnel can record the debugging results on the debugging terminal and feedback them to the control terminal, so that the control terminal can update the device status information.
