Description

Integrated LED lighting control system with troubleshooting and countermeasures

Underground parking lots and public areas of large buildings including apartments are equipped with lighting. The lighting is configured to control ON / OFF according to the presence or absence of the detection of the movement or presence of a vehicle or a person.

For the power saving of such a lamp, a technology that combines an infrared sensor for detecting a person and an optical sensor for detecting an illuminance is introduced. However, such a technology has a disadvantage in that it is easily turned off if the human motion is large, and a complex sensor for detecting the presence of a human in real time by combining an ultrasonic sensor with an infrared sensor has been developed.

On the other hand, in the case of installing lighting lamps, such as fluorescent lights for the underground parking lot, it is necessary to adjust the illumination for power saving. To this end, a dimming ballast has been developed, and a separate control box for each lamp is used to control it directly by rotary control or mast control.

However, when dimming ballast is applied to fluorescent lamps and used for lighting of underground parking lot in large buildings such as apartments, it is not easy to control ON / OFF frequently due to the characteristics of fluorescent lamps, and various sensors and switchboards must be installed separately for each fluorescent lamp. As well as the cost of the furnace is greatly increased, a lot of wiring is entangled during electrical work, there is a problem that labor costs and construction period increases.

Recently, ordinary LED lights are installed instead of fluorescent lamps for electric savings, or dimming LED lights with dimming control functions are installed to increase electric savings. At this time, in order to facilitate the dimming operation, the human body sensor and the control panel for signal transmission processing must be installed for each light, which is a great burden in terms of design, construction and operation.

In addition, when installing and operating a lighting control system by sensors in public places such as large parking lots, specific areas are divided and turned on and off to maximize power savings. In this case, the lighting is only turned on within a predetermined area irrespective of the position of the person, and the user is experiencing a great inconvenience.

In addition, in the case of a lighting system installed in a large-scale work site, the performance degradation and failure of the system is reduced to problems such as the safety of the workplace, the reduction of the work efficiency of the operator, the severe quality degradation and the loss cost due to the repair period.

Recently, with the advancement of the industry and the improvement of living standards, researches on individual lighting control systems that satisfy the appropriate illuminance according to the pleasant and comfortable living environment and the place and use the minimum energy are continuously conducted. With the introduction of lighting, the importance of dimming control is being emphasized.

Among them, in the event of a failure of the lighting control system, the necessity of a failure diagnosis system together with the lighting system is necessary to maintain a comfortable illumination and reduce the dangerous environment caused by the deterioration of illumination, considering the fatigue of the visual organ, which is one of the most sensitive parts of the human sensory organs. This situation is emerging.

On the other hand, the fault diagnosis system was started by applying a model-based approach to the complex chemical process control field, and as the interest in the need increased, it entered the 70's. Advance to aviation. In the 80's, Kalman filter and observer were applied. In the 90's, fault detection and diagnosis methods were developed by comparing parameter estimation and residual detection. Increasing interest in informatization using electronic components and computers, and lighting systems for maintaining a comfortable space are being automated and advanced along with Energy Monitoring System (EMS) and Energy Control System (ECS). There is a problem that it is more difficult for the operator to grasp the impact on the degradation and degree of comfort.

Therefore, in order to optimally operate the lighting system, there is a need for introducing a failure detection and diagnosis system for an illumination system that can provide an operator with information necessary for performing failure detection and maintenance diagnosis decisions.

In addition, deterioration of system performance and occurrence of failures result in deterioration of workplace safety, reduction of operator's work efficiency, and serious quality deterioration. Therefore, in order to optimally operate the lighting system, it is necessary for the operator to perform failure detection and maintenance diagnosis decisions. There is a need to introduce a failure detection and diagnosis system for lighting systems that can provide the necessary information.

The present invention is designed to solve the problems of the conventional lighting control system as described above, the main purpose of the development of the failure detection and diagnosis system is to monitor the operation status of the various components, and to reduce the performance of the component failure occurs By predicting the failure and the location that causes the abnormal operation or predicting in advance, it analyzes and diagnoses the degree of the failure to provide an appropriate treatment method to the operator.

In addition, energy efficiency and cost reduction through efficient operation of the lighting system, creating a comfortable indoor environment and improving the reliability of the lighting system to provide domestic energy saving and lighting system automation system.

In the embodiment of the present invention, the system performance of a lighting system used in a place where a large number of management lights such as a factory, a classroom, a classroom, etc., a place that is difficult to manage such as a street lamp, a tunnel, and an automobile assembly plant in which a 24-hour production activity is performed And a database that can be applied to failure detection and diagnostic algorithms of lighting systems that can predict not only the power consumption, but also the status of each lighting, and analyze the various state values of the actual tester bed to take active countermeasures. We will develop a fault diagnosis system to find an efficient lighting system.

Therefore, when the LED lighting integrated control system having a failure diagnosis and coping function according to an embodiment of the present invention, one of the provided LED lights do not operate due to breakage or failure of the illumination sensor 630. Alternatively, when the power detection sensor 620 is recognized, the integrated control unit 100 maintains a constant average illuminance of a predetermined area through illumination control for a predetermined LED light installed around the failed or damaged LED light. It is possible to build a system.

When the motion detection sensor 610 does not detect whether the motion is detected, the integrated control unit 100 performs an illumination control function for a predetermined LED light installed around the failed or damaged LED light. You can stop.

When the LED illumination integrated control system having a failure diagnosis and coping function having the above configuration, the illumination sensor 630 and the power sensor is provided on one side of the LED illumination lamp 500, the illumination sensor 630 Measures the power input to each of the LED lamp 500, the illumination sensor 630 measures the illumination of the light irradiated from the LED lamp 500 to measure the real-time measured data value to the controller 300 side send.

In general, the lifespan of a light source including a fluorescent lamp is not called a lifespan until the light source does not output any light. The lifespan of the LED is regarded as 50,000 hours, and the light continues to be emitted after 50,000 hours. It can output, but light output will decrease over time.

In addition, offices and houses recommend the lifespan of the elapsed time until it is reduced to 70% of the initial luminous flux.If the current or voltage supplied to the LED is higher than the rated value, the light output is improved, but the lifetime is reduced. Therefore, stable current or voltage supply is needed.

Therefore, as the temperature in the LED (semiconductor) rises, the light output decreases and the life span also decreases. Therefore, since the LED luminaire does not radiate heat to infrared rays, heat radiation using conduction or convection is necessary.

In addition, Switching Mode Power Supply (SMPS) is the most essential component of LED lighting, and in general, shortening of SMPS lifespan is a cause of shortening the life of LED lighting.

The SMPS is a device that converts an alternating current (AC) current supplied from the outside into a direct current (DC) current to meet the conditions of various electronic devices. Irregular power supply (220 VAC) causes electronic performance degradation, and preventing this is one of the SMPS roles. Even if the input voltage fluctuates, the output voltage to the LED lamp is always kept constant. Among the electronic parts that make up the SMPS, the least durable parts are electrolytic capacitors (capacitors) that are weak to heat, and if they exceed 60 degrees, their efficiency decreases and their lifespans are shortened rapidly. Heat sink or heat sink FAN is applied.

In general, when the ambient temperature is 50 degrees, the lifespan of the degree capacitor is generally 7 years, while the degree capacitor is generally used for SMPS.

Therefore, in relation to the LED lighting device, the factors influencing the life of the lighting are regarded as the life of the LED lighting itself and the life of the SMP 400. In addition, when the lighting system reaches the end of its service life, it is difficult to overcome the safety accidents and quality deterioration by the brightness of the surrounding lights alone, and thus the loss cost during the repair replacement period can be reduced. And configuration for the system.

1 and 2, in the lighting control system having a failure diagnosis and coping function according to an embodiment of the present invention, by converting the AC power input to the DC power using a rectifier circuit to the LED lighting lamp 500 And a switched mode power supply (SMPS) 400 having two or more connected in parallel; An LED lamp 500 electrically connected to the SMP 400 unit and configured to irradiate light to the outside using a DC power source as an electric power source, and to adjust an amount of irradiated light; The motion sensor 610 for detecting the presence or operation of a person or object, the power sensor 620 for sensing the amount of power input, and the LED lamp 500 is provided on one side of the LED lamp 500. A sensor unit 600 including an illuminance sensor 630 for measuring illuminance irradiated to the light; A controller (IC) for controlling the illuminance of the SMP 400 and the LED lighting according to a dimming command; According to the input data value detected by the sensor unit 600, the LED illuminant 500 to control the illumination through the dimming control, the power supply to the SM 400 400 that can operate normally in the SM 400 unit An integrated control unit 100 (ICP: integrated control program) for controlling the energization; The MC unit 200 transmits a control command from the integrated control unit 100 to the control unit 300, and transmits and receives a data value measured through the sensor unit 600 from the control unit 300 by wire or wirelessly. (MC: mid controller);

When the LED illumination integrated control system having a failure diagnosis and coping function having the above configuration, the illumination sensor 630 and the power sensor is provided on one side of the LED illumination lamp 500, the illumination sensor 630 Measures the power input to each of the LED lamp 500, the illumination sensor 630 measures the illumination of the light irradiated from the LED lamp 500 to measure the real-time measured data value to the controller 300 side To transmit.

For example, when one of the LED lamps 500 installed in a specific area has reached the end of its life or is damaged, it is determined through data values measured by the power sensor 620 or the illuminance sensor 630. In addition, the integrated control unit 300 adjusts the illuminance of a predetermined LED illuminator 500 provided around the LED illuminator 500 that is determined to be the abnormal state toward the control unit 300, thereby adjusting the average illuminance of the corresponding area. To keep it running.

On the other hand, the component that has a great impact on the life of the LED lighting is the SMP 400. The SMPS 400 switching mode power supply (SMPS) is the most essential component of the characteristics of the LED lighting, and in general, shortening the life of the SMPS is the cause of shortening the lifetime of the LED lighting.

The SMP is a device that converts an AC current supplied from the outside into a DC current to suit the conditions of various electronic devices, and supply of irregular power (220VAC) may cause deterioration of electronic device performance. Preventing this is one of the roles of the SMPS, and the output voltage to the LED lamp is kept constant even when there is a change in the input voltage.

Among the electronic parts constituting the SMP 400, the weakest parts are electrolytic capacitors (capacitors) that are weak to heat, and if they exceed 60 degrees, their efficiency decreases and their lifespans are dramatically shortened, causing SMPS failure. SMPS has a heat sink or heat sink (FAN) that can dissipate heat.

In the embodiment of the present invention, the integrated control unit 100, the SMP 400 to control, so that the power is supplied to the SMP 400 operating in the normal side of the two or more 400 S 400 connected in parallel. It also functions.

Through the above configuration, it is possible to establish a system to actively cope with the failure of the LED lighting system, and to minimize the loss of safety accidents or quality degradation caused by the failure.

FIG. 5 is a diagram illustrating a result of operating a system when a specific LED light is broken in an LED lighting integrated control system having a failure diagnosis and coping function according to an exemplary embodiment of the present invention.

In the normal state, as shown in FIG. 3, each LED illuminator 500 irradiates light at a level of 80% of the maximum brightness with respect to a corresponding area with uniform illuminance. In this case, as shown in FIG. 4, when a specific LED lamp 500 fails and fails to operate normally, data about an abnormal state measured by the illumination sensor 630 or the power detection sensor 620 is received. The integrated control unit 100 controls to maintain the average illuminance for the corresponding area area by changing the illuminance of the predetermined LED illuminator 500 around the failed LED illuminator 500 through the control unit 300. do.
