Abstract

The present invention relates to a hybrid wired / wireless lighting dimming control system using a set / reset latch method, and more specifically, to a hybrid wired / wireless lighting dimming control system using a set / reset latch method that significantly improves the stability and reliability of lighting control independently of the communication status by introducing a method of commanding the lighting state with a single pulse signal and permanently fixing (latching) the corresponding state within the control device to solve the lighting instability and flickering problems that occur in the event of communication failures in conventional continuous signal control methods. Through this, unlike conventional technology which relied on continuous control signals and caused the lighting to become unstable or flicker upon communication interruption, the dimming control command is transmitted as a single pulse signal, and the state is permanently latched and maintained within the dimming controller. As a result, even if the communication connection between the transmitter and receiver is temporarily interrupted, the lighting can stably maintain the last commanded brightness level or ON / OFF state.

Description

Technology Field

[0001] The present invention relates to a hybrid wired / wireless lighting dimming control system using a set / reset latch method, and more specifically, to a hybrid wired / wireless lighting dimming control system using a set / reset latch method that significantly improves the stability and reliability of lighting control independently of the communication status by introducing a method of commanding the lighting state with a single pulse signal and permanently fixing (latching) the corresponding state within the control device to solve the lighting instability and flickering problems that occur in the event of communication failures in conventional continuous signal control methods. Background Technology

[0003] Conventional large-scale sports lighting control systems have primarily controlled lighting by adopting the Pulse Width Modulation (PWM) dimming method.

[0004] This method is based on the principle of controlling illuminance by changing the duty cycle of the signal transmitted to the lighting converter.

[0005] In such a system, to maintain a constant lighting state (brightness), a continuous control signal had to be constantly supplied from the upper controller (transmitter) or receiver to the dimming controller.

[0006] This continuous signal is in the form of an analog voltage representing the brightness level of the lighting or a PWM square wave with a fixed duty cycle, and in large facilities such as stadiums, wired communication such as RS485 was utilized as the primary control method, primarily in environments where laying communication lines is relatively easy.

[0007] However, this PWM continuous control signal method caused critical problems, particularly in environments controlling a large number of floodlights, such as stadiums and golf courses.

[0008] The most serious problem was that maintaining the lighting state relied entirely on continuous control signals input from an external source. If a temporary failure occurred in the upper-level controller, or if the supply of continuous control signals was interrupted due to communication line instability caused by external factors (aging, disconnection, noise, etc.), the lighting would lose control, resulting in rapid changes in brightness or severe flickering.

[0009] Such lighting instability was a factor that caused significant disruptions to the progress of games or increased the risk of safety accidents in large-scale facilities.

[0010] Furthermore, there was a risk that the control functions of the entire system could be paralyzed in the event of a communication failure. In addition, relying solely on wired communication made establishing a network highly inefficient in terms of cost and time in large, complex outdoor environments like golf courses, and it also presented limitations in terms of flexibility when expanding the system. Prior art literature

[0012] Korean Registered Patent No. 10-1580260 (Registration Date: Dec. 18, 2015) The problem to be solved

[0013] The present invention was devised to solve the above problems and aims to provide a hybrid wired / wireless lighting dimming control system using a Set / Reset latch method that applies a Set / Reset latch control method to transmit a command to change the state of the lighting as a single (pulse) signal, and the latch control unit of the dimming controller permanently remembers this command to store and maintain the final control state independently of the communication state, thereby stably maintaining the lighting in the last commanded state (on or off, specific brightness) even when communication is interrupted, thereby fundamentally eliminating disruptions in game progress and the risk of safety accidents and significantly improving the reliability of the system.

[0014] Furthermore, another objective of the present invention is to provide a hybrid wired / wireless lighting dimming control system using a Set / Reset latch type, which can reduce system construction costs and time and increase operational efficiency by implementing a hybrid wired / wireless communication system that allows for the selective use of LoRa wireless communication and RS485 wired communication depending on the situation, thereby enabling the selection of the optimal communication method according to the characteristics of the installation site, as the construction of a wired communication network is inefficient in areas where laying communication lines is difficult or in complex terrain.

[0015] In addition, another objective of the present invention is to provide a hybrid wired / wireless lighting dimming control system of the Set / Reset latch type, which can accurately adjust brightness by stably supplying a dimming voltage in the range of 2V to 10V required for each light while controlling the illuminance of multiple floodlights collectively with a single control signal by designing the output amplifier section inside the dimming controller to connect multiple OP-AMPs in parallel to secure a sufficient and stable output current required for multiple converters. means of solving the problem

[0017] The present invention has the following features to solve the above problem.

[0018] The present invention is a hybrid wired / wireless lighting dimming control system for controlling a plurality of lights, comprising: a transmitter that transmits a dimming control command to each of a plurality of lights; a receiver connected to the transmitter to communicate via at least one of wired and wireless methods, receiving a dimming control command from the transmitter, and outputting a set signal pulse or a reset signal pulse in a single step to control the state of the corresponding light based on the received dimming control command; a dimming controller that receives the single set signal pulse or the reset signal pulse from the receiver, stores the final control state of the light independently of the communication state, generates a PWM signal having a duty cycle corresponding to the brightness level of the light according to the stored control state, and converts / outputs a dimming voltage in the range of 2V to 10V based on the generated PWM signal; and a converter disposed in each of a plurality of lights to adjust and supply power to the light connected to itself based on the dimming voltage received from the dimming controller.

[0019] Here, the receiver includes a hybrid communication module that selectively uses LoRa wireless communication and RS485 wired communication with the transmitter.

[0020] In addition, the dimming controller includes a latch control unit that receives a one-time Set signal pulse or Reset signal pulse from the receiver and stores the final control state of the lighting independently of the communication state, a PWM generator that generates a PWM signal having a duty cycle corresponding to the brightness level of the lighting according to the stored final control state, and an OP-AMP-based output amplifier that receives the PWM signal from the PWM generator and converts it into a dimming voltage in the range of 2V to 10V and outputs it.

[0021] In addition, the latch control unit fixes the final control state of the corresponding light to ON upon receiving the single-shot Set signal pulse, fixes the final control state of the corresponding light to OFF upon receiving the single-shot Reset signal pulse, and stably maintains the lighting state according to the single-shot Set signal or single-shot Reset signal received last, even when the communication connection between the transmitter and the receiver is disconnected.

[0022] In addition, the output amplifier of the above dimming controller has a plurality of OP-AMPs connected in parallel to increase the output current.

[0023] In addition, the above latch control unit includes a plurality of MCUs, and each MCU independently manages the final control state of a plurality of lighting groups through a plurality of single-shot Set signal and single-shot Reset signal pairs. Effects of the invention

[0025] According to the present invention, unlike conventional technology which relies on continuous control signals and causes lighting to become unstable or flicker upon communication interruption, the dimming control command is transmitted as a single pulse signal, and the state is permanently latched and maintained within the dimming controller. Consequently, even if the communication connection between the transmitter and receiver is temporarily interrupted, the lighting can stably maintain the last commanded brightness level or ON / OFF state.

[0026] This provides a decisive effect in maximizing the operational reliability of the system by fundamentally eliminating the risk of game interruptions and safety accidents caused by light flickering during matches.

[0027] Furthermore, by implementing a hybrid communication system that selectively utilizes LoRa wireless communication and RS485 wired communication, flexible response to various installation environments becomes possible. In areas where laying communication cables is difficult, such as golf courses or vast outdoor facilities, stable control is enabled without cable installation work by utilizing LoRa wireless communication, which results in a significant reduction in the cost and time required for building communication infrastructure.

[0028] On the other hand, in environments where wired communication is readily available, data stability can be ensured by using RS485 communication, providing operational efficiency by allowing the selection of the optimal communication method according to field conditions.

[0029] In addition, by connecting multiple OP-AMPs in parallel to the output amplifier of the dimming controller to increase the output current, sufficient current capacity is secured to stably drive multiple lighting converters on a single control line, and by precisely converting the PWM signal generated in the latch controller into a dimming voltage of 2V to 10V based on the OP-AMP and providing it to the converter, the quality of the control signal supplied to the lighting is improved and accurate and uniform illumination control is enabled.

[0042] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0043] FIG. 1 is a block diagram schematically illustrating the internal configuration of a hybrid wired / wireless lighting dimming control system according to an embodiment of the present invention, FIG. 2 is a diagram showing the configuration of a receiver according to an embodiment of the present invention, and FIG. 3 is a diagram showing the configuration of a dimming controller according to an embodiment of the present invention.

[0044] Referring to the drawings, a hybrid wired / wireless lighting dimming control system (1000) according to an embodiment of the present invention comprises: a transmitter (100) that transmits a dimming control command to each of a plurality of lights; a receiver (200) that is connected to the transmitter (100) to communicate via at least one of wired and wireless methods, receives a dimming control command from the transmitter (100), and outputs a set signal pulse or a reset signal pulse once to control the state of the corresponding light based on the received dimming control command; a dimming controller (300) that receives the once-outset set signal pulse or the reset signal pulse from the receiver (200), stores the final control state of the light independently of the communication state, generates a PWM signal having a duty cycle corresponding to the brightness level of the light according to the stored control state, and converts / outputs a dimming voltage in the range of 2V to 10V based on the generated PWM signal; and a dimming controller that is disposed in each of the plurality of lights and adjusts and supplies power to the light connected to itself based on the dimming voltage received from the dimming controller (300). It consists of a converter (400).

[0045] Here, the transmitter (100) is positioned between the user interface and the receiver (200), which is the actual lighting control unit, and acts as a communication gateway that receives and converts commands.

[0046] This transmitter (100) is the first hardware element that initiates the control flow of the system and receives a dimming control command from a user terminal (e.g., a PC) via wired communication. This command contains command information for setting a desired brightness level or ON / OFF state for the user terminal.

[0047] The most important feature of such a transmitter (100) is the function of converting the communication method to transmit the received command to a lower-level receiver (200). The transmitter (100) converts the wired command received from the user into a wired communication or wireless communication method and outputs it.

[0048] This is an essential component for implementing the hybrid communication system, which is a key feature of the present invention. The transmitter (100) can transmit commands to the receiver (200) by selectively using LoRa wireless communication and RS485 wired communication to flexibly respond to environments where laying communication lines is difficult (e.g., golf courses).

[0049] Accordingly, the configuration of the transmitter (100) includes a wired communication module (110) with a user terminal, which is a user interface, and a first hybrid communication module (120) responsible for wired and wireless communication with a receiver (200).

[0050] That is, the transmitter (100) goes beyond simply transmitting a signal and performs an addressing and packaging process to transmit commands to the corresponding lighting group or individual receiver on a large-scale floodlight control network.

[0051] Accordingly, the receiver (200) generates a final one-time Set / Reset latch pulse based on the command received from the transmitter (100), and the flexible communication conversion capability of the transmitter (100) can contribute to increasing the system's construction cost and operational efficiency.

[0052] Meanwhile, the receiver (200) is positioned between the transmitter (100) and the dimming controller (300) and serves as a key conversion device that receives a communication signal and converts it into a single-shot pulse command signal suitable for latch control and outputs it. The receiver (200) may include a second hybrid communication module (210) as a component.

[0053] The most important feature of such a receiver (200) is that it functions as a hybrid transceiver. This allows it to receive dimming control commands from a transmitter (100) via at least one of LoRa wireless communication and RS485 wired communication.

[0054] Such hybrid communication capability enables flexible response to various installation environments, such as golf courses where laying communication lines is difficult. The receiver (200) outputs a Set signal pulse or a Reset signal pulse to control the state of the corresponding light based on the received dimming control command.

[0055] At this time, the signal output by the receiver (200) is a single-shot pulse signal, unlike a conventional continuous signal. The receiver (200) outputs an ON signal to the corresponding number output pin, maintaining the ON state only for 100ms to 300ms and then turning OFF.

[0056] This short pulse-shaped Set / Reset signal is immediately transmitted to the latch control unit (310) of the dimming controller (300).

[0057] Thanks to the functional features of the receiver (200) as described above, the dimming controller (300) can stably maintain the final control state without relying on the continuity of the communication signal.

[0058] Meanwhile, the above dimming controller (300) is the most important component of the system and serves as a key intelligent control device that converts one-time commands received from the receiver (200) into a permanent control state and generates and outputs a dimming voltage to drive the actual lighting load.

[0059] The dimming controller (300) may be composed of a latch control unit (310) that receives a single Set signal pulse or Reset signal pulse from the receiver (200) and stores the final control state of the lighting independently of the communication state, a PWM generator (320) that generates a PWM signal having a duty cycle corresponding to the brightness level of the lighting according to the stored final control state, and an OP-AMP-based output amplifier (330) that receives the PWM signal from the PWM generator (320), converts it into a dimming voltage in the range of 2V to 10V, and outputs it.

[0060] Here, the latch control unit (310) includes a microcontroller unit such as an Arduino and receives a single Set signal pulse or Reset signal pulse input from the receiver (200).

[0061] Accordingly, the latch control unit (310) interprets this short pulse command and stores the final control state (ON / OFF or specific brightness level) of the corresponding light in internal memory through firmware development logic and locks (latches) it.

[0062] Thanks to this feature, the dimming controller (300) can stably maintain the last commanded lighting state even when the communication connection is disconnected, regardless of the state of the transmitter (100) and receiver (200).

[0063] In addition, the stored control state is immediately transmitted to the PWM generator (320), and this PWM generator (320) also corresponds to the function of the microcontroller unit of FIG. 3 and generates a PWM signal having a duty cycle corresponding to the brightness level of the light according to the latched state.

[0064] Finally, the output amplifier (330) receives the generated PWM signal and adjusts it to a voltage suitable for 2V to 10V dimming through an OP-AMP circuit, and outputs it to the converter (400).

[0065] In particular, to control a large number of high-output floodlights in a group, the circuit is designed with a structure that increases the output current by connecting the output terminals of multiple OP-AMPs in parallel, as shown in part A of Fig. 3.

[0066] As such, the dimming controller (300) is a core module that clearly separates the functions of communication and control and maximizes the stability and reliability of the system through its self-maintaining state.

[0067] Meanwhile, the converter (400) receives a control signal from the dimming controller (300) and acts as an LED driver that regulates and supplies the power required for multiple lights (floodlights). The converter (400) is a device located at the final output terminal of the system that executes dimming control commands as physical brightness changes.

[0068] The main features of such a converter (400) are the interpretation of the dimming voltage signal and the regulation of the actual power. The converter (400) receives a dimming voltage in the range of 2V to 10V from the OP-AMP-based output amplifier (330) of the dimming controller (300).

[0069] This dimming voltage is not the actual driving voltage required for the light, but a control signal that commands the brightness level of the light.

[0070] Accordingly, the converter (400) interprets the magnitude of this dimming voltage and converts the power received from the AC main power source into a constant DC power (current or voltage) that matches the rated specifications of the lighting (floodlight).

[0071] For example, the internal driving circuit is adjusted so that when 10V is received, the maximum power corresponding to maximum brightness is supplied to the light, and when 2V is received, the minimum power corresponding to minimum brightness or off is supplied.

[0072] According to one example, the present invention has a structure in which converters 1 through N are connected to a dimming controller (300) to collectively control the illumination of a large amount of high-output sports floodlights.

[0073] Accordingly, each converter (400) is grouped together and its brightness is adjusted simultaneously according to a single control command of the dimming controller (300).

[0074] In addition, since the converter (400) operates based on a stable dimming voltage through the latch control of the dimming controller (300), it can induce the effect of driving the light while stably maintaining the commanded brightness without the light flickering phenomenon that occurred due to conventional communication instability.

[0075] Meanwhile, as a modified example of the present invention, the latch control unit (310) may include a plurality of MCUs, and each MCU may be configured to independently manage the final control state of a plurality of lighting groups through a plurality of single-shot Set signals and single-shot Reset signal pairs.

[0076] This has two main objectives: expanding the control capabilities of large-scale lighting systems and improving system stability.

[0077] A latch control unit (310) according to a modified example of the present invention is composed of multiple MCUs to distribute control tasks, instead of concentrating all control loads on a single microcontroller unit (MCU).

[0078] Since each MCU is dedicated to managing a specific number of lighting groups, the control channels for lighting groups that the system can accommodate are expanded, which is very suitable for environments where a large number of floodlights must be controlled collectively, such as stadiums or large facilities.

[0079] In addition, multiple MCUs independently managing the final control state for each lighting group through multiple single-shot Set and single-shot Reset signal pairs provides distributed stability of control.

[0080] Even if an error occurs in one MCU, the control state of the lighting group managed by the other MCU remains unaffected and is maintained normally. Each MCU applies the single-shot pulse command transmitted from the receiver (200) only to its assigned lighting group and stores the corresponding state through internal software flip-flop (latch) logic.

[0081] As the control state is managed independently by each MCU, the control load of the entire system is evenly distributed, and the overall stability and reliability of the system are improved compared to a single MCU configuration.

[0082] The purpose of the latch control unit (310) of the present invention being composed of a plurality of MCUs is to block the influence on lighting of other groups. Even if one MCU fails, the lighting groups managed by the other MCUs are not affected and can continue to maintain a normal control state and PWM output.

[0083] Therefore, the group matched with the faulty MCU may be unable to sustain PWM output based on the already latched state, potentially preventing the lighting from operating normally; however, since the group matched with other MCUs continues to operate independently, the overall fault tolerance of the system is improved.

[0084] Meanwhile, as another example of a variation in the multiple MCU configuration of the latch control unit (310) described above, the latch control unit (310) can be configured with two MCUs, one of which functions as a master MCU and the other as a sub MCU.

[0085] These master MCUs and sub MCUs are connected to each lighting group, and under normal circumstances, the master MCU operates in an active state responsible for latch control and PWM output for all lighting groups. At this time, the sub MCU remains in a standby state.

[0086] Accordingly, the sub-MCU immediately takes over control as soon as the master MCU fails, enabling the resumption of PWM output without interruption. This ensures the continuity of lighting services in the event of not only communication failures but also failures in the control unit itself.

[0087] Of course, the sub-MCU continuously checks whether the master MCU is active or faulty according to the settings, and if the master MCU meets the preset conditions, determines it to be inactive or faulty and performs control of all lighting groups.

[0088] To determine such inactivity or failure, the sub-MCU can be configured to monitor whether the master MCU is operating normally through logic such as a heartbeat signal.

[0089] In addition, for status synchronization when performing monitoring, the final latch status for each lighting group immediately before the master MCU determines a failure is transmitted together with the heartbeat signal.

[0090] Originally, the heartbeat signal serves as a simple survival signal in which the master MCU periodically informs the sub-MCU that "I am still alive and operating normally." However, in this invention, to enhance system reliability, the heartbeat signal is extended to transmit not only "survival status" but also "important current status information."

[0091] Accordingly, the status information included in the heartbeat is configured as a data packet containing, for example, the current last latched status information for each lighting group (e.g., Group 1: ON, Group 2: 50% brightness, Group 3: OFF, etc.).

[0092] In addition, this status information packet is transmitted to the sub-MCU at short intervals (e.g., every 10ms or 100ms) carried on a heartbeat signal. Transmission can be performed via a dedicated communication channel between the two MCUs (e.g., SPI, I2C, or UART).

[0093] Whenever the sub-MCU receives this heartbeat packet, it updates the latch status of all light groups stored in internal memory or registers to the latest state of the master.

[0094] Through this synchronization mechanism, the sub-MCU always retains the most recent control state of the master MCU.

[0095] If the sub-MCU does not receive a heartbeat signal from the master MCU for a set time (Timeout), it is determined that the master MCU has failed.

[0096] Then, the sub MCU immediately switches from the standby state to the active state to take control, and the sub MCU activates the PWM generator (320) based on the latch state that was last updated and stored just before the master failure, and resumes the dimming voltage output without interruption.

[0097] In such a master MCU and sub MCU configuration, since all lighting groups are physically connected to both MCUs, measures to prevent output conflict (Bus Contention) are essential.

[0098] In other words, when the master MCU is operating normally, the PWM output terminal of the sub-MCU can be configured to maintain a high impedance state, or a physical switch (relay) or diode isolation circuit can be used at the output terminal to prevent the output signals of both MCUs from being transmitted to the converter simultaneously and causing interference.

[0099] While the increase in unit costs due to the increased complexity of such hardware and firmware logic and additional components is inevitable, it is necessary for system stability in environments requiring high reliability, such as sports lighting.

[0101] This project (result) is the result of the 'Cheonan City Optical Technology Industry Development Support Phase 2 Project,' which was carried out with funding from Cheonan City Hall.

[0103] Although preferred embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments described above. That is, those skilled in the art to which the present invention pertains can make numerous changes and modifications to the present invention without departing from the spirit and scope of the appended claims, and all such appropriate changes and modifications should be deemed to fall within the scope of the present invention as equivalents.
