With an aircraft obstruction light inspection device such as that described in Patent Document 1, the inspection worker cannot determine whether the light is faulty unless he or she visually checks the light, so the inspection worker must move to a location where he or she can see the light, which can make the inspection process time-consuming.

The present invention aims to provide an aviation obstruction light inspection system that can reduce the effort required to inspect aviation obstruction lights.

The aviation obstruction light inspection system of the present invention is an aviation obstruction light inspection system that inspects aviation obstruction lights installed on structures constructed on the ground, and includes an inspection device and a communication device capable of communicating with the inspection device. The inspection device includes a detection unit that detects lighting information related to the lighting state of the aviation obstruction lights, a processing unit that performs processing to determine whether there is an abnormality related to the lighting of the aviation obstruction lights based on the lighting information detected by the detection unit and outputs the processing result, and a communication unit that communicates with the communication device. The communication device includes a transmission unit that transmits an inspection start signal to the communication unit, a receiving unit that receives the processing result, and a display unit that displays result information related to the processing result received by the receiving unit. When the communication unit receives the inspection start signal, the processing unit outputs the processing result based on the lighting information, and the communication unit transmits the processing result to the receiving unit.

With this configuration, the inspection device and the communication device can communicate, the detection unit detects the illumination information of the aviation obstruction lights, the processing unit makes a judgment based on the detection, and the display unit of the communication device displays the processing result. Therefore, if the inspection worker carries the communication device, he or she can ascertain whether or not there is an abnormality in the illumination state of the aviation obstruction lights without visually checking the lights. This reduces the effort required for inspection.

The aviation obstruction light may also include a lamp serving as a light source and a lamp control unit that controls the lighting of the lamp, the detection unit may include a control detection unit that detects control state information that indicates the control state of the lamp control unit, and the processing unit may be configured to perform processing to determine whether or not there is an abnormality in the control of the lamp control unit based on the control state information detected by the control detection unit.

With this configuration, the detection unit detects the control status information of the lamp control unit, and the processing unit determines whether or not there is an abnormality in the control of the lamp control unit based on the detection result, so it is possible to grasp whether or not there is an abnormality in the control of the lamp control unit.

The lamp control unit also includes at least one control device for controlling the lighting of the lamp, the control detection unit is configured to detect device information indicating the state of the control device as the control status information, and the processing unit can be configured to perform processing to determine whether or not there is an abnormality in the control of the lamp control unit based on the device information detected by the control detection unit.

With this configuration, the detection unit detects the device information of the control device, and the processing unit determines whether or not there is an abnormality in the control of the lamp control unit based on the detection result, so it is possible to grasp whether or not there is an abnormality in the control of the lamp control unit.

The lamp control unit may also be configured to include a broken core detection unit that outputs information regarding a broken core of the lamp, the control detection unit may include a detection state detection unit that detects detection state information regarding the detection operation state of the broken core detection unit, and the processing unit may be configured to perform processing to determine whether or not there is an abnormality in the operation state of the broken core detection unit based on the detection state information detected by the detection state detection unit.

With this configuration, the detection unit detects the detection state information, and the processing unit determines whether or not there is an abnormality in the operating state of the core breakage detection unit based on the detection result, so it is possible to grasp whether or not there is an abnormality in the operating state of the core breakage detection unit.

The light control unit is configured to operate by receiving power from an external source, the control detection unit includes a power detection unit that detects power information related to whether or not power is being supplied to the light control unit from the outside, and the processing unit can be configured to perform processing to determine whether or not there is an abnormality in the power supply to the aviation obstruction light based on the power information detected by the power detection unit.

With this configuration, the detection unit detects the power supply information, and the processing unit determines whether or not there is an abnormality in the power supply to the aviation obstruction light based on the detection result, so it is possible to grasp whether or not there is an abnormality in the power supply to the aviation obstruction light.

The light control unit may also be configured to include a circuit breaker that cuts off the current flowing through the light control unit, the control detection unit may include a circuit breaker detection unit that detects that the circuit breaker has cut off the current, and the processing unit may be configured to perform processing to determine that an abnormality has occurred when the circuit breaker detection unit detects that the circuit breaker has cut off the current.

With this configuration, the detection unit detects the interruption of the current by the circuit breaker, and the processing unit determines that there is an abnormality when the detection unit detects that the circuit breaker has interrupted the current, so it is possible to check whether there is an abnormality that would cause the circuit breaker to interrupt the current.

An aviation obstruction light inspection system 4 according to one embodiment of the present invention will be described with reference to Figures 1 to 5.

First, the aviation obstruction light 1 inspected by the aviation obstruction light inspection system 4 of this embodiment will be described with reference to Figures 1 to 3.

As shown in Figures 1 and 2, the aviation obstruction light 1 is a device for indicating the presence of a structure constructed on the ground to flying aircraft, and in this embodiment, it is installed on a tower structure T (a power transmission tower). Specifically, the aviation obstruction light 1 comprises a lamp 11 that serves as a light source, and a lamp control unit 2 that controls the lighting of the lamp 11. The aviation obstruction light 1 of this embodiment is a line-powered aviation obstruction light 1 in which both the lamp 11 and the lamp control unit 2 are primarily powered by a commercial power source.

The lighting devices 11 are provided in multiple locations on a structure and are devices that, by emitting light, indicate the presence of the structure to aircraft flying by. Specifically, the lighting devices 11 are located at the top end and the middle of the structure in the vertical direction. When power is supplied to the lighting devices 11, the lighting devices 11 are configured to be lit in one of the following modes: constant lighting, blinking at a predetermined cycle, or flashing at a predetermined cycle. In this embodiment, the lighting devices 11 are configured to be lit constantly when power is supplied, and are lit in a blinking manner when a switch 24 (described later) operates to intermittently supply power to the lighting devices 11.

The lamp control unit 2 controls the lighting of the lamp 11, and in this embodiment, controls the lighting of the lamp 11 by controlling the supply of power to the lamp 11. The lamp control unit 2 also has at least one control device for controlling the lighting of the lamp 11. In this embodiment, the lamp control unit 2 has a circuit breaker 21 as a control device that cuts off the supplied current, a flasher 22 as a control device that emits information about the environment in which the aviation obstruction light 1 is installed, a lighting command unit 23 as a control device that receives information emitted by the flasher 22 or information transmitted from the outside and emits information for turning on or off the lamp 11, a switch 24 as a control device that opens and closes a circuit for supplying power to the lamp 11 based on the information emitted by the lighting command unit 23, and a broken core detection unit 25 that outputs information about a broken core of the lamp 11. Such a lamp control unit 2 is arranged inside a control panel provided in a structure, and is configured to operate by receiving AC power from a commercial power source. In addition, the lamp control unit 2 is equipped with a backup power supply (not shown) that temporarily supplies power to the lamp 11 and the lamp control unit 2 if the power supply from the external power source is interrupted.

The circuit breaker 21 is a control device that opens the electric circuit and cuts off the current from the external power source to the light control unit 2 when an overcurrent flows from the external power source to the light control unit 2. For example, the circuit breaker 21 opens the electric circuit when a ground fault, short circuit, leakage current, etc. occurs in the electric circuit on the load side of the circuit breaker 21 and an overcurrent flows. In other words, the circuit breaker 21 is a control switch that is configured to close the electric circuit under normal conditions (when no overcurrent flows) and open the electric circuit when an overcurrent flows.

The flasher 22 is a control device that emits information about the environment in which the light 11 is installed. The flasher 22 of this embodiment emits information about the brightness in the environment in which the light 11 is installed. The flasher 22 of this embodiment is equipped with an illuminance sensor that detects the brightness of the environment in which the light 11 is installed, and emits information that the illuminance is below the predetermined illuminance while the illuminance (brightness) detected by the illuminance sensor is below a predetermined illuminance. The flasher 22 also has a switch that is turned ON when the illuminance detected by the illuminance sensor is below a predetermined value and turned OFF when the illuminance detected by the illuminance sensor is above the predetermined value, and is configured to emit information that the illuminance is below the predetermined illuminance when the switch is ON. In other words, the flasher 22 is a control switch that has a switch that is turned ON or OFF depending on the brightness. The flasher 22 of this embodiment is configured to emit information (signal) that the illuminance is below the predetermined illuminance by a relay circuit.

The lighting command unit 23 issues information to turn on or off the lamp 11 based on information input from the flasher 22 or from the outside (e.g., the inspection device 5) as described below. Specifically, the lighting command unit 23 issues information to turn on the lamp 11 when information is input from the flasher 22 that the illuminance is below a predetermined illuminance, or when information is input from the outside to turn on the lamp 11. The lighting command unit 23 also issues information to turn off the lamp 11 when there is no input from the flasher 22 or from the outside. The lighting command unit 23 in this embodiment has a relay circuit that operates in conjunction with the flasher 22, and is configured to issue information (signal) to turn on the lamp 11 when the switch of the flasher 22 is turned ON.

The switch 24 is a control device that opens and closes a circuit that supplies current to the lamp 11, and in this embodiment is a contactless switch. Specifically, the switch 24 is configured to open and close a circuit that supplies current to the lamp 11 based on information issued by another control device, and in this embodiment, is configured to open and close a circuit that supplies power to the lamp 11 based on information issued by the lighting command unit 23. The switch 24 cuts off the power supply to the lamp 11 by opening the circuit, and supplies power to the lamp 11 by closing the circuit. Specifically, the switch 24 closes the circuit (supplies power to the lamp 11) when the lighting command unit 23 issues information to turn on the lamp 11, and opens the circuit (does not supply power to the lamp 11) when the lighting command unit 23 does not issue information to turn on the lamp 11.

The broken core detection unit 25 detects the lighting state of the lamp 11 and outputs information about the broken core of the lamp 11. Specifically, the broken core detection unit 25 includes a sensor portion that acquires information about the lighting state of the lamp 11, and a control portion that determines whether the lamp 11 is broken and the cumulative lighting time of the lamp 11 based on the information acquired by the sensor portion, and outputs the result. If the broken core detection unit 25 determines that the lamp 11 is broken, it outputs broken core information, and if it determines that the lamp 11 has been lit for a predetermined time or more in total, it outputs time overage information. The broken core detection unit 25 acquires information about the lighting state of each of the multiple lamps 11 and outputs the result. The broken core detection unit 25 of this embodiment is configured to acquire information about the lighting state of the lamp 11 from the power supplied to the lamp 11, but is not limited to such a configuration. For example, it can be configured to acquire information about the lighting state of the lamp 11 by sensing light generated by the lighting of the lamp 11. A broken core does not only refer to the breakage of the light emitter (filament) in the lamp 11 as an incandescent light bulb, but also includes, for example, the failure of the parts that emit light in the lamp 11 as an LED light due to deterioration over time. In other words, a broken core refers to any abnormality that makes the lamp 11 unable to emit light.

The broken core detection unit 25 is configured to operate on power converted from the power supplied to the lamp control unit 2, and more specifically, operates on power converted to DC by the converter 26. The converter 26 is a device that converts AC power to DC. The circuit that supplies power to the broken core detection unit 25 is configured to branch between the circuit breaker 21 and the switch 24, and is configured to supply power to the broken core detection unit 25 regardless of the operation of the switch 24. That is, in the present embodiment, power is constantly supplied to the broken core detection unit 25 under normal conditions (when there are no abnormalities in the devices and the power supply from outside).

In the aviation obstruction light 1 configured as described above, when the brightness in the installation environment falls below a predetermined brightness (for example, at night or in the rain), the flasher 22 issues information that the illuminance falls below the predetermined illuminance, and the lighting command unit 23, which receives this information, issues information to turn on the light unit 11. The switch 24 then closes the circuit to supply power to the light unit 11, which then lights up. In addition, in the aviation obstruction light 1, when the brightness in the installation environment becomes equal to or greater than the predetermined brightness (for example, during the day), the flasher 22 and lighting command unit 23 do not issue information, and the switch 24 opens the circuit to stop supplying power to the light unit 11, which then turns off the light unit 11.

Next, the aviation obstruction light inspection system 4 that inspects the aviation obstruction light 1 will be described with reference to Figures 1 to 5. As shown in Figures 1 and 2, the aviation obstruction light inspection system 4 includes an inspection device 5 and a communication device 6 that can communicate with the inspection device 5.

As shown in FIG. 4, the inspection device 5 includes a detection unit 51 that detects lighting information related to the lighting state of the aviation obstruction light 1, a status storage unit 52 that stores the lighting information detected by the detection unit 51, a processing unit 53 that performs processing to determine whether or not there is an abnormality related to the lighting of the aviation obstruction light 1 based on the lighting information and outputs the processing result, and a communication unit 54 that communicates with the communication device 6. Such an inspection device 5 is provided in a control panel placed on a steel tower, for example, and is supplied with power from an external power source (specifically, a commercial power source). The inspection device 5 of this embodiment is configured as an integral part of the light control unit 2, and is configured to be supplied with power from the same power source as the light control unit 2.

3 and 4, the detector 51 is provided in the aviation obstruction light 1 and detects lighting information related to the lighting state of the lamp 11 in the aviation obstruction light 1. The detector 51 in this embodiment is a control detector provided in the lamp control unit 2 and detects control state information related to the control state of the lamp control unit 2 for lighting the lamp 11. In this embodiment, the detector 51 detects the operating state or power supply state of each device constituting the aviation obstruction light 1 as lighting information. The detector 51 includes a first detector 511 as a power source detector, a second detector 512 as a cutoff detector, a third detector 513 as a blinking detector, a fourth detector 514 as a detection state detector, and a fifth detector 515 as a lamp current detector. Each detector 51 is provided in the control device of the lamp control unit 2 and detects device information indicating the state of the control device, or is arranged in the circuit of the lamp control unit 2 and is configured to detect the power supplied to each device of the aviation obstruction light 1. In this embodiment, the detection unit 51 that detects device information detects switch information related to the state of the control switch as device information.

The first detection unit 511 detects power information related to whether or not power is being supplied from an external power source. Specifically, the first detection unit 511 is disposed on the side closest to the power source in the lamp control unit 2, and detects whether or not power is being supplied from an external power source to the lamp control unit 2. That is, the first detection unit 511 is configured to be able to detect whether or not power is being supplied from an external power source to the lamp control unit 2, regardless of whether or not the circuit breaker 21 has cut off the power. The first detection unit 511 of this embodiment is capable of detecting power supplied from an external power source, and is configured to emit a signal when the power supply from the external power source to the lamp control unit 2 is cut off. Specifically, it is a power sensor with a break contact that switches OFF when power supply is detected, and switches ON when power supply is not detected.

The second detection unit 512 detects that the circuit breaker 21 has interrupted the current. Specifically, the second detection unit 512 is a sensor configured to detect the operation of the circuit breaker 21 as a control switch and emit a signal when the circuit breaker 21 opens the electric circuit (when the current is interrupted). The second detection unit 512 of this embodiment includes a switch that operates in conjunction with a control switch related to opening and closing the electric circuit of the circuit breaker 21, and is configured such that the switch is OFF while the circuit breaker 21 closes the electric circuit, and the switch of the second detection unit 512 is ON and emits a signal when the circuit breaker 21 opens the electric circuit. In other words, the second detection unit 512 is configured to detect switch information related to the state of the control switch.

The third detection unit 513 detects the operating state of the flasher 22. Specifically, the third detection unit 513 is a sensor configured to detect the operation of the flasher 22 as a control switch and emit a signal while the flasher 22 does not emit information that the illuminance is below a predetermined illuminance. The third detection unit 513 of this embodiment is capable of detecting the emission of information from the flasher 22, and has a break contact that turns the switch OFF when it detects that the flasher 22 has emitted information that the illuminance is below a predetermined illuminance, and turns ON when it does not detect (does not emit) that the flasher 22 has emitted information that the illuminance is below the predetermined illuminance. Specifically, the third detection unit 513 is configured to operate in conjunction with the relay of the flasher 22. That is, the third detection unit 513 is configured to detect switch information regarding the state of the control switch (switch of the relay of the flasher 22).

The fourth detection unit 514 detects detection state information related to the operating status of the broken core detection unit 25. The fourth detection unit 514 can also detect whether the broken core detection unit 25 is in a state in which it can operate properly. Specifically, the fourth detection unit 514 can detect whether power is being supplied to the broken core detection unit 25. The fourth detection unit 514 in this embodiment is a power sensor arranged between the circuit breaker 21 and the broken core detection unit 25, and is specifically arranged between the converter 26 and the broken core detection unit 25. The fourth detection unit 514 can detect the power converted by the converter 26 and supplied to the broken core detection unit 25, and is configured to emit a signal when the power supply to the broken core detection unit 25 is interrupted. Specifically, it is a power sensor having a break contact that switches OFF when power supply is detected and switches ON when power supply is not detected.

The fifth detection unit 515 detects the power supplied to the lamp 11. Specifically, the fifth detection unit 515 is a power sensor arranged between the lamp 11 and the switch 24. In this embodiment, the fifth detection unit 515 is capable of measuring the current of the power supplied to each lamp 11 and outputs the measurement result.

As shown in FIG. 4, the status holding unit 52 is configured to hold the results detected by the detection unit 51. In this embodiment, the status holding unit 52 is configured to hold a signal when the detection unit 51 issues one until a reset input is made. Specifically, the status holding unit 52 includes an abnormal status holding unit 521 that always holds a signal when the detection unit 51 issues one, and a fault status holding unit 522 that holds a signal only when a signal (lighting information) related to the lighting state of the aviation obstruction light 1 detected by the detection unit 51 satisfies a predetermined condition.

The abnormal state holding unit 521 is configured to hold the result detected by the detection unit 51. The abnormal state holding unit 521 of this embodiment is configured to hold the signal when the detection unit 51 issues a signal. Specifically, when the first detection unit 511, the second detection unit 512, or the fourth detection unit 514 issues a signal, the abnormal state holding unit 521 holds the signal. That is, when the detection unit 51 detects a state in which the power supply is interrupted in the aviation obstruction light 1 (a state in which there is no power supply to each device or a state in which the input of the external power source is cut off), the abnormal state holding unit 521 holds the detection result. When a signal is input from the detection unit 51 once, even if the signal from the detection unit 51 is subsequently interrupted, the abnormal state holding unit 521 is configured to hold the signal until a reset input is made. Furthermore, when the core breakage detection unit 25 issues core breakage information, the abnormal state holding unit 521 of this embodiment holds the core breakage information.

The fault state holding unit 522 is configured to hold a signal when the result detected by the detection unit 51 satisfies a predetermined condition. Specifically, the fault state holding unit 522 is configured to hold a signal emitted by the third detection unit 513 when the signal satisfies a predetermined condition. In this embodiment, the fault state holding unit 522 is configured to hold a signal when the third detection unit 513 continuously emits a signal for a predetermined time (e.g., 24 hours) or more. That is, the fault state holding unit 522 holds a signal emitted by the third detection unit 513 when the flasher 22 is OFF for a predetermined time (e.g., 24 hours) or more (when the flasher 22 does not emit information that the illuminance is below a predetermined illuminance) based on the signal of the third detection unit 513. Such a fault state holding unit 522 is configured to hold a signal emitted by the detection unit 51 once it satisfies a predetermined condition, even if the signal from the detection unit 51 is subsequently interrupted, until a reset input is made.

The processing unit 53 is a computer that performs processing to determine whether or not there is an abnormality regarding the lighting of the aviation obstruction light 1 based on the lighting information detected by the detection unit 51, and outputs the processing result. In this embodiment, the processing unit 53 performs processing to determine whether or not there is an abnormality in the control of the lamp control unit 2 based on the control state information detected by the detection unit 51. Specifically, the processing unit 53 determines whether or not there is an abnormality regarding the lighting of the aviation obstruction light 1 based on the signal emitted by the detection unit 51. The specific processing content regarding the judgment by the processing unit 53 will be described later. In addition, the processing unit 53 determines and outputs the state regarding the lighting of the lamp 11 based on the information regarding the broken core of the lamp 11 detected by the broken core detection unit 25. The processing unit 53 outputs the processing result to the communication unit 54, and instructs to turn on the lamp 11 based on the processing result, and outputs information to turn on the lamp 11 to the lighting command unit 23.

The processing unit 53 is also configured to perform self-diagnosis to determine whether the processing operation of the processing unit 53 itself is normal. Specifically, the processing unit 53 determines whether an abnormality has occurred in the processing operation of each device constituting the processing unit 53 itself. In this embodiment, the processing unit 53 performs self-diagnosis to determine whether there is an abnormality in the ROM or RAM of the computer constituting the processing unit 53. The processing unit 53 also performs self-diagnosis by measuring the number of CPU restarts and retaining information related to the number of restarts. The processing unit 53 of this embodiment outputs information related to the presence or absence of an abnormality in the ROM or RAM and the number of CPU restarts as a result of the self-diagnosis.

The communication unit 54 is a part capable of communicating with the communication device 6, and in this embodiment, is capable of wireless communication with the communication unit 54. The communication unit 54 also receives an inspection start signal from the communication device 6 regarding the start of inspection, and transmits the processing result to the communication device 6. When the communication unit 54 receives the inspection start signal, it transmits a signal to the processing unit 53 to start processing for inspection.

2 and 5, the communication device 6 includes a transmitting unit 61 that transmits an inspection start signal to the communication unit 54, a receiving unit 62 that receives the processing result, and a display unit 63 that displays result information related to the processing result received by the receiving unit 62. The communication device 6 of this embodiment is a portable wireless communication device.

The transmitting unit 61 is a component configured to transmit an inspection start signal to the communication unit 54. The transmitting unit 61 in this embodiment includes an operation unit 611, and is configured to transmit an inspection start signal when an input related to starting an inspection is made to the operation unit 611. The operation unit 611 in this embodiment is a push button labeled "start inspection," and is configured to transmit an inspection start signal when pressed. Note that the configuration is not limited to this, and it can also be configured to automatically transmit an inspection start signal when, for example, the inspection device 5 corresponding to the aviation obstruction light 1 to be inspected approaches close enough to enable wireless communication.

The receiving unit 62 is a component configured to receive the processing results transmitted by the communication unit 54. In this embodiment, the receiving unit 62 goes into a standby state to wait for the reception of the processing results after the transmitting unit 61 transmits the inspection start information. Furthermore, when the receiving unit 62 receives the processing results, it outputs the received information to the display unit 63.

As shown in FIG. 5, the display unit 63 displays result information related to the processing result received by the receiving unit 62. Specifically, the display unit 63 displays a normal display, which is a display indicating that there is no abnormality in the aviation obstruction light 1, and an abnormal display, which is a display indicating that there is an abnormality in the aviation obstruction light 1. The display unit 63 of this embodiment has a plurality of light-emitting units 631, and displays the result information by emitting light from the light-emitting unit 631 corresponding to the result information. Specifically, the display unit 63 has a normal display unit 631a which is the light-emitting unit 631 corresponding to the normal display, and an abnormal state display unit (a broken core display unit 631b, a failure display unit 631c, and an abnormality display unit 631d) which is the light-emitting unit 631 corresponding to the abnormality display. In addition, a plurality of abnormal state display units are provided corresponding to the types of abnormalities to be displayed. The abnormal state display unit of this embodiment includes a broken core display unit 631b that displays an abnormality related to a broken core of the lamp 11, a fault display unit 631c that displays a fault in the control device of the lamp control unit 2, and an abnormality display unit 631d that displays an abnormal state occurring in the lamp control unit 2. The fault display unit 631c of this embodiment displays a fault in the flasher 22. The normal display unit 631a is the light-emitting unit 631 located adjacent to the part marked "No abnormality", the broken core display unit 631b is the light-emitting unit 631 located adjacent to the part marked "Broken core", the fault display unit 631c is the light-emitting unit 631 located adjacent to the part marked "Flasher fault", and the abnormality display unit 631d is the light-emitting unit 631 located adjacent to the part marked "Control panel abnormality".

The following describes the inspection of aviation obstruction lights 1 using the aviation obstruction light inspection system 4 configured as described above.

The aviation obstruction light inspection system 4 constantly monitors the aviation obstruction light 1 and acquires lighting information of the aviation obstruction light 1. Specifically, in the aviation obstruction light inspection system 4, the detection unit 51 constantly monitors the lighting state of the aviation obstruction light 1, and emits a signal when the detection unit 51 detects a predetermined state. The signal detected by the detection unit 51 is also held by the status holding unit 52. Specifically, when the power supply to the entire or part of the equipment for the aviation obstruction light 1 is interrupted, the first detection unit, the second detection unit, or the fourth detection unit detects the interruption of the power supply and emits a signal, and the abnormality status holding unit 521 holds the signal. Also, when the flasher 22 does not emit information that the illuminance of the aviation obstruction light 1 is below a predetermined illuminance, the third detection unit 513 detects the above state and emits a signal, and when the signal continues for a predetermined time (24 hours) or more, the fault status holding unit 522 holds the signal emitted by the third detection unit 513. Furthermore, in the aviation obstruction light inspection system 4, information regarding the power supply status to the light 11 detected by the fifth detection unit 515 is input to the processing unit 53 each time. Also, in the aviation obstruction light inspection system 4, time-exceeded information issued by the broken core detection unit 25 is input to the processing unit 53.

The worker inspecting the aviation obstruction light 1 operates the operation unit 611 of the communication device 6 to start the inspection. When the operation unit 611 is operated, the transmission unit 61 of the communication device 6 transmits inspection start information to the communication unit 54 of the inspection device 5. When the communication unit 54 receives the inspection start information, it issues a signal to the processing unit 53 to start processing for the inspection.

The processing unit 53, which has received a signal to start the inspection, performs a process to determine whether or not there is an abnormality regarding the lighting of the aviation obstruction light 1. The processing unit 53 determines whether or not there is an abnormality regarding the lighting of the aviation obstruction light 1 based on the lighting information of the aviation obstruction light 1 detected by the detection unit 51. Specifically, the processing unit 53 determines whether or not there is an abnormality regarding the lighting of the aviation obstruction light 1 based on the signal held by the status holding unit 52. In this embodiment, the processing unit 53 determines that there is an abnormality regarding the lighting of the aviation obstruction light 1 when the status holding unit 52 holds a signal or when time-exceeded information is input, and determines that there is no abnormality regarding the lighting of the aviation obstruction light 1 when the status holding unit 52 does not hold a signal. Furthermore, when it is determined that there is an abnormality, the processing unit 53 determines the type of abnormality. Specifically, when the abnormality status holding unit 521 holds a signal, the processing unit 53 determines that an abnormal state has occurred in the lamp control unit 2, when the failure status holding unit 522 holds a signal, the processing unit 53 determines that a failure has occurred in the control device of the lamp control unit 2, and when time-exceeded information is input, the processing unit 53 determines that the lamp 11 is broken. Then, the processing unit 53 outputs the results of each of the above judgments as the processing result. Note that, when there are multiple abnormalities, the processing unit 53 judges that multiple abnormalities have occurred. For example, when both the abnormality state storage unit 521 and the fault state storage unit 522 are holding signals, it is judged that an abnormal state has occurred in the lamp control unit 2 and that a fault has occurred in the control device of the lamp control unit 2. The processing result of the processing unit 53 is output to the transmission unit 61, and the communication unit 54 transmits the processing result to the communication device 6. In addition, the processing unit 53 judges whether or not there is an abnormality in the power supply to the lamp 11 based on information on the status of the current supply to the lamp 11 input from the fifth detection unit. For example, when there is a large variation in the current flowing through each lamp 11, when an overcurrent is flowing, or when no current is flowing continuously for a predetermined time or more (for example, 24 hours), it is judged that there is an abnormality in the power supply to the lamp 11, and it is judged that an abnormal state has occurred in the lamp control unit 2.

The processing unit 53 also issues a command to turn on the lamp 11 based on the above processing result. Specifically, the processing unit 53 issues a command to turn on the lamp 11 in a different lighting pattern depending on the processing result. In this embodiment, if the control unit determines that there is no abnormality in the lighting of the aviation obstruction light 1, it issues a command regarding a lighting pattern that causes the lamp 11 to blink, and if it determines that there is an abnormality in the lighting of the aviation obstruction light 1, it issues a command regarding a lighting pattern that causes the lamp 11 to be continuously lit (not blinking). The command to turn on the lamp 11 issued by the processing unit 53 is input to the lighting command unit 23 as an external input, and the lighting command unit 23 issues information to open and close the switch 24, so that the lamp 11 is turned on according to the command issued by the processing unit 53.

When the communication unit 54 transmits the processing result to the communication device 6, the receiving unit 62 receives the transmitted processing result and outputs the received information (processing result) to the display unit 63. The display unit 63 to which the processing result is input displays a display corresponding to the input processing result. In this embodiment, the display unit 63 displays the processing result by illuminating the light-emitting unit 631 corresponding to the processing result. Specifically, when the processing result indicates that there is no abnormality regarding the illumination of the aviation obstruction light 1, the display unit 63 illuminates the normal display unit 631a, and when the processing result indicates that there is an abnormality regarding the illumination of the aviation obstruction light 1, the display unit 63 illuminates the light-emitting unit 631 corresponding to the type of abnormality among the broken core display unit 631b, the malfunction display unit 631c, and the abnormality display unit 631d.

The worker inspecting the aviation obstruction light 1 determines whether there is an abnormality in the aviation obstruction light 1 based on the display on the display unit 63, and performs additional inspection and repair work as necessary. For example, if the display unit 63 displays a normal display, the worker determines that there is no abnormality in the aviation obstruction light 1 and ends the inspection work. On the other hand, if the display unit 63 displays an abnormality, the worker performs additional inspection work on the aviation obstruction light 1 and equipment repair work. Then, after the additional inspection work and equipment repair work are completed, a reset input is made to the status holding unit 52, and the signal held by the status holding unit 52 is released.

According to the aviation obstruction light inspection system 4 configured as described above, the inspection device 5 and the communication device 6 are capable of communicating with each other, and the detection unit 51 detects the illumination information of the aviation obstruction light 1, the processing unit 53 makes a judgment based on the detection, and the display unit 63 of the communication device 6 displays the processing result. Therefore, if the inspection worker carries the communication device 6, he or she can ascertain whether or not there is an abnormality in the illumination state of the aviation obstruction light 1 without visually checking the light 11. This reduces the effort required for inspection.

In addition, the detection unit 51 detects the control status information of the lamp control unit 2, and the processing unit 53 determines whether or not there is an abnormality in the control of the lamp control unit 2 based on the detection result, so it is possible to grasp whether or not there is an abnormality in the control of the lamp control unit 2.

Furthermore, the detection unit 51 detects the device information of the control device, and the processing unit 53 determines whether or not there is an abnormality in the control of the lamp control unit 2 based on the detection result, so it is possible to grasp whether or not there is an abnormality in the control of the lamp control unit 2.

In addition, the detection unit 51 detects the detection status information, and the processing unit 53 determines whether or not there is an abnormality in the operating status of the core breakage detection unit 25 based on the detection result, so that it is possible to grasp whether or not there is an abnormality in the operating status of the core breakage detection unit 25.

Furthermore, the detection unit 51 detects the power supply information, and the processing unit 53 determines whether or not there is an abnormality in the power supply of the aviation obstruction light 1 based on the detection result, so that it is possible to grasp whether or not there is an abnormality in the power supply of the aviation obstruction light 1.

In addition, the detection unit 51 detects the interruption of the current by the circuit breaker 21, and the processing unit 53 determines that there is an abnormality when the detection unit 51 detects that the circuit breaker 21 has interrupted the current, so it is possible to check whether there is an abnormality that would cause the circuit breaker 21 to interrupt the current.

Furthermore, the detection unit 51 detects the status of the power supply to the lamp 11, and the processing unit 53 performs processing to determine whether or not there is an abnormality in the power supply to the lamp 11 based on the status of the power supply to the lamp 11 detected by the detection unit 51. Therefore, it is possible to determine an abnormality when current is not being supplied appropriately to the lamp 11.

The detection unit 51 also detects switch information related to the operating state of the control switch, and the processing unit 53 performs processing to determine whether or not there is an abnormality in the control of the lamp control unit 2 based on the switch information detected by the detection unit 51. Therefore, it is possible to grasp whether or not there is an abnormality in the control of the lamp control unit 2.

The inspection device 5 further includes a status storage unit 52 that stores the detection results of the detection unit 51, and when the processing unit 53 receives an inspection start signal, the status storage unit 52 performs processing to determine whether or not there is an abnormality in the lamp control unit 2 based on the detection results stored therein. Therefore, since the detection results from the previous inspection to the current inspection are stored and an abnormality can be determined and output based on the detection results, it is possible to grasp the abnormality even if, for example, a temporary abnormality occurs and is then resolved.

The lamp control unit 2 also includes a broken core detection unit 25 that detects a broken core in the lamp 11. The broken core detection unit 25 is configured to transmit a broken core signal to the processing unit 53 when it detects a broken core in the lamp 11. When the processing unit 53 receives the broken core signal, it determines that there is an abnormality in the lamp 11. Therefore, an abnormality in the aviation obstruction light 1 can be determined based on both the detection by the detection unit 51 and the detection by the broken core detection unit 25.

Furthermore, the processing unit 53 is configured to be able to execute a self-diagnosis to detect an abnormality in the processing unit 53 itself, and outputs the result of the self-diagnosis as the processing result. Therefore, the presence or absence of an abnormality in the processing unit 53 can be determined based on the result of the self-diagnosis, and by having the display unit 63 display the processing result of the processing unit 53 that has an abnormality, it is possible to prevent an abnormality in the aviation obstruction light 1 from being overlooked.

The above describes an embodiment of the present invention by way of example, but the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, the aviation obstruction light 1 has been described as being installed on a tower structure T (a power transmission tower), but the present invention is not limited to this configuration and can also be applied to aviation obstruction lights 1 installed on structures such as high-rise buildings, chimneys, and heavy machinery such as cranes.

In addition, the lamp control unit 2 has been described as controlling the lamp 11 so that the lamp 11 is turned on or off depending on the brightness of the installation environment, but it is not limited to this configuration, and it can also be configured to control the lamp 11 to be always on, or to control the turning on and off of the lamp 11 based on time.

Furthermore, although the above description is directed to a case where the inspection device 5 is provided integrally with the lamp control unit 2, the present invention is not limited to such a configuration, and it is also possible to adopt a configuration in which the inspection device 5 is provided separately from the lamp control unit 2. When adopting such a configuration, for example, it is also possible to adopt a configuration in which the detection unit is attached to the lamp control unit 2.

The communication device 6 can also be provided with a display screen 632 as the display unit 63 that can display the image of the lamp 11 imaged by the imaging unit C, and configured to display the image of the lamp 11 as the processing result. With this configuration, the actual illumination state of the lamp 11 can be confirmed remotely. The processing result can also be displayed on the display unit 63 as text information, etc.

Furthermore, the communication device 6 is not limited to the device shown in the figure, and can be configured to become the communication device 6 by installing an application on a general-purpose device (such as a notebook computer or tablet computer). In such a configuration, the operation unit 611 can be configured as a virtual button provided on the computer screen, and the computer screen can be configured as the display unit 63.
