In addition, the power supply unit (1) adjusts the overall output according to the status of each electrical component when multiple electrical components, such as lighting devices, are connected, so as to prevent overload of the electrical components. To this end, the power supply unit (1) may include a circuit unit (11), an operation control unit (12), a failure diagnosis unit (13), a temperature monitoring unit (14), and an output control unit (15).

The operation control unit (12) can block the operation of the circuit unit (11) when the passenger moves further than a set distance from the electrical equipment, and can operate it only when the passenger moves closer than the set distance, thereby reducing the use of components and power consumption. To this end, the operation control unit (12) can include a distance information receiving module (121), a reference distance setting module (122), an operation initiation module (123), and an operation blocking module (124).

Accordingly, the reference distance setting module (122) can appropriately set various reference distances depending on the type of electrical equipment and the installation environment, thereby enabling the optimized operation of the power supply device (1) to be controlled.

[0052] The above operation start module (123) is configured to supply power to the circuit unit (11) to start operation, and can automatically start operation of the power supply device (1) when the distance to the passenger transmitted by the proximity sensing device (2) becomes closer than the set reference distance.

Preferably, the primary side output receiving module (133) can receive primary side output information when the secondary side output falls below the reference output. Accordingly, if there is no problem with the secondary side output supplied to the electrical equipment, the primary side information is not received, and only when there is a problem with the secondary side output, the primary side output information is received to check the fault status, thereby enabling efficient diagnosis of the fault location.

The temperature analysis unit (141) can be performed before installation for each power supply unit (1), and analysis of the temperature change can be performed while changing the output and the ambient temperature. To this end, the temperature analysis unit (141) can include a temperature information storage module (141a), an operating information storage module (141b), an ambient temperature storage module (141c), and a correlation analysis module (141d).

[0061] The above temperature information storage module (141a) is configured to store temperature information of the power supply unit (1), and receives and stores temperature information measured through a separate temperature sensor formed within the power supply unit (1).

[0062] The above-mentioned operating information storage module (141b) is configured to store information on the operating status of the power supply device (1), and can measure and store information according to the output of the power supply device (1).

[0063] The above ambient temperature storage module (141c) is configured to store temperature information around the power supply unit (1), and can receive and store temperature information measured separately around the power supply unit (1).

[0064] The above correlation analysis module (141d) is configured to analyze the correlation between the operating status of the power supply unit (1), the ambient temperature, and the temperature of the power supply unit (1). It inputs the output and ambient temperature information for each power supply unit (1) as variables and analyzes the correlation with the temperature of the power supply unit (1). The above correlation analysis module (141d) can derive a correlation model by a machine learning method such as an artificial neural network.

[0065] The above risk detection unit (142) is configured to detect a risk state of the power supply device (1) according to temperature, and uses the correlation model derived by the correlation analysis module (141d) to derive an appropriate temperature and determine a risk state using this, thereby enabling accurate detection of a risk state. To this end, the risk detection unit (142) may include a temperature information receiving module (142a), an operation information receiving module (142b), an external temperature receiving module (142c), an appropriate temperature calculation module (142d), an operation stop module (142e), and a risk notification module (142f).

[0066] The above temperature information receiving module (142a) is configured to receive temperature information of the power supply device (1), and can receive temperature information measured inside the power supply device (1) in real time.

[0067] The above-mentioned operation information receiving module (142b) is configured to receive information on the operation status of the power supply device (1), and can receive output information according to the voltage and current of the power supply device (1).

[0068] The above external temperature receiving module (142c) is configured to receive temperature information around the power supply unit (1), and can receive information measured by a separate sensor that measures the temperature around the power supply unit (1).

[0069] The above-mentioned appropriate temperature calculation module (142d) is configured to calculate the appropriate temperature according to the current operating status and ambient temperature of the power supply device (1), and can calculate the appropriate temperature information during normal operation by inputting the current output and ambient temperature information into the correlation model derived by the above-mentioned correlation analysis module (141d).

[0070] The above operation stop module (142e) is configured to stop the operation of the power supply device (1) when it is determined that the power supply device (1) is in a dangerous state, and can be configured to determine that the current temperature of the power supply device (1) received by the temperature information receiving module (142a) exceeds the appropriate temperature calculated by the appropriate temperature calculation module (142d) by a set amount or more when the current temperature of the power supply device (1) received by the temperature information receiving module (142a) exceeds the appropriate temperature calculated by the appropriate temperature calculation module (142d) by a set amount or more.

[0071] The above-mentioned risk notification module (142f) is configured to notify the risk state of the power supply device (1), and can simultaneously notify the risk state when the operation is stopped by the above-mentioned operation stop module (142e), and can generate a separate risk notification signal in the power supply device (1).

[0072] The above inspection request unit (143) is configured to notify a state in which the power supply unit (1) requires inspection, and can recognize and notify in advance a case in which a danger may arise due to frequent occurrence of abnormal temperatures, even though the danger detection unit (142) has not determined the state to be dangerous. Through this, the inspection request unit (143) can prevent damage due to the danger in advance by notifying in advance of the possibility of danger occurring due to overheating. To this end, the inspection request unit (143) may include an abnormal range setting module (143a), an abnormal range detection module (143b), an operation stop module (143c), an operation resume module (143d), an abnormality index calculation module (143e), and an inspection request notification module (143f).

[0073] The above-mentioned abnormal range setting module (143a) is configured to set an abnormal range that can be judged as an abnormal temperature state, and can set a temperature range between a certain range below a value exceeding a set level from an appropriate temperature judged as a dangerous state by the above-mentioned risk detection unit (142) and a value judged as a dangerous state, that is, a temperature range between a certain level exceeding the appropriate temperature and a value judged as a dangerous state, as an abnormal range.

[0074] The above-mentioned abnormal range detection module (143b) is configured to detect that the temperature of the power supply device (1) reaches an abnormal range, and detects that the temperature received in real time by the temperature information receiving module (142a) reaches an abnormal range, and can detect and store information about the degree and time of exceeding the appropriate temperature.

[0075] The above operation stop module (143c) is configured to stop the operation of the power supply device (1) when the temperature of the power supply device (1) reaches an abnormal range, and can temporarily stop the operation to quickly return to an appropriate temperature.

[0076] The above operation resumption module (143d) is configured to resume operation of the power supply device (1) when the temperature of the power supply device (1) falls below an abnormal range, thereby automatically resuming operation to minimize inconvenience and damage caused by operation stoppage.

[0077] The above-mentioned abnormality index calculation module (143e) is configured to calculate an abnormality index indicating the degree and frequency of temperature abnormality, so that when the temperature frequently reaches an abnormal range due to frequent abnormalities, it can be determined that an inspection is required. Therefore, the above-mentioned abnormality index calculation module (143e) can increase the efficiency of management by requesting an inspection only when the temperature of the power supply device (1) reaches an abnormal range rather than immediately requesting an inspection, so that management is performed excluding temporary abnormalities. The above-mentioned abnormality index calculation module (143e) can calculate a higher abnormality index as the degree and time of exceeding the appropriate temperature increase. For example, the abnormality index can be calculated by multiplying the degree of exceeding the appropriate temperature within the abnormal range by the time of exceeding it. In addition, the above-mentioned abnormality index calculation module (143e) can calculate an abnormality index for each set unit period, so that an accurate degree of abnormality can be calculated.

[0079] The above output control unit (15) is configured to control the output through the power supply unit (1), and when multiple electrical components, such as lighting devices, are connected to one power supply unit (1), the overall output is controlled according to the output of each electrical component. When multiple electrical components are connected to the power supply unit (1), the power supply unit (1) only controls the overall output, and the overall output is evenly distributed and supplied to the multiple electrical components. However, when a failure occurs in one of the electrical components and the output is reduced, the output for the corresponding electrical component is distributed and supplied to the remaining electrical components, which causes an overload in the remaining electrical components. For example, when eight 25W lighting devices are connected to a 200W power supply unit (1), and a failure occurs in one of the lighting devices, 28.7W of power is supplied to the remaining seven lighting devices, causing an overload. Accordingly, in this case, the output control unit (15) can prevent overload by adjusting the output of the power supply unit (1) to 175 W to match the remaining electrical components. To this end, the output control unit (15) may include an output information detection module (151), a reference output setting module (152), an output reduction detection module (153), an overall output adjustment module (154), and a failure occurrence notification module (155).

[0080] The above output information detection module (151) is configured to detect the output supplied to each electrical component, and can detect the output by measuring the voltage and current supplied to each electrical component.

[0081] The above standard output setting module (152) is configured to set the standard output for each electrical component, and sets the output value supplied to the electrical component when the electrical component is operating normally as the standard output.

[0082] The above output reduction detection module (153) is configured to detect a reduction in the output of a specific electrical component, and detects an electrical component whose output drops beyond a set level from the standard output due to a failure of the electrical component.

[0083] The above overall output adjustment module (154) is configured to adjust the overall output of the power supply unit (1) when a decrease in output of a specific electrical component is detected by the output decrease detection module (153), thereby stopping the power supply to the electrical component whose output has decreased due to a failure and adjusting the overall output to match the remaining electrical components. Therefore, as described above, the above overall output adjustment module (154) adjusts the overall output of the power supply unit (1) to match the standard output of the remaining electrical components, thereby preventing overload from occurring in the electrical components.

[0084] The above failure occurrence notification module (155) is configured to notify information about an electrical component in which a failure has occurred, and can output information about an electrical component detected by the output reduction detection module (153) to the power supply unit (1) itself or transmit it to a separate terminal.

[0085] The above proximity sensing device (2) is configured to be formed in an electrical component and to measure the distance to a passenger approaching the electrical component. It can be formed in an electrical component such as a monitor, light, CCTV, etc., and can measure the distance by transmitting and receiving ultrasonic waves and transmit the measured distance to a power supply device (1).

[0086] The above-mentioned electric equipment (3) is configured to operate by receiving power from the power supply device (1), and various equipment such as lighting devices, broadcasting devices, display devices, CCTV, and video recording devices can be applied.

[0087] In the above, the applicant has described various embodiments of the present invention, but such embodiments are only examples of implementing the technical idea of ​​the present invention, and any change or modification that implements the technical idea of ​​the present invention should be interpreted as falling within the scope of the present invention.
