Summary of the Invention

Problems to be Solved by the Invention

[0004] As shown in Patent Document 1, in the chain-type flash lamp system installed on the runway of an airport, the flash lamps are used as approach lights and are installed at intervals of 30 m for a length of 900 m in principle, about 8 to 29 lamps in the direction from the approach direction of the aircraft toward the end of the runway.

[0005] The flash lamps installed on the runway of an airport tend to experience illumination reduction, non-lighting, etc. due to aging deterioration, failure, etc. caused by long-term light emission and exposure to sunlight, wind, and rain. When such situations occur, the overall illumination of the flash lamps decreases, and it may not meet the safety standards set by the Ministry of Land, Infrastructure, Transport and Tourism. Therefore, maintenance of the chain-type flash lamp system is essential.

[0006] The management of the flash lamp having a light-emitting part and a power supply part is performed on a display panel such as a liquid crystal panel installed in the controller. When an abnormality occurs in the light-emitting part or the like of the flash lamp, "communication abnormality" is displayed for each flash lamp on the display panel of the controller.

[0007] Conventional inspection methods confirmed the abnormality of the controller by removing the cable connecting the light-emitting part and the power supply part of the strobe light and checking whether the "communication abnormality" was displayed on the controller. However, in this method, since all the LEDs mounted on the light-emitting part are turned off, it was impossible to accurately grasp what percentage of the mounted LEDs caused the controller's abnormality to be reported due to the LEDs turning off.

[0008] Therefore, an object of the present invention is to provide a strobe light core breakage occurrence device capable of inspecting the abnormality of a controller by checking the lighting state of the light-emitting part of the strobe light at the site such as an airport where the strobe light is installed.

Means for Solving the Problems

[0009] To achieve the above object, the strobe light core breakage occurrence device of the present invention is A strobe light core breakage occurrence device provided with a pair of connection ports and a plurality of ON / OFF switches on the surface of the main body, The pair of connection ports each have a plurality of connection parts, and the plurality of connection parts of each of them are conductively connected in a one-to-one correspondence, and at least a part of them can be turned ON / OFF via the switch.

Effects of the Invention

[0010] According to the present invention, by using a portable and small-sized strobe light core breakage occurrence device to check the lighting state of the light-emitting part of the strobe light, it is possible to easily and accurately perform abnormality inspections of controllers and the like, reducing the work burden of the measurer. Thus, great effects can be obtained in terms of man-hours, costs, etc., and it can contribute to the safe and secure operation of airports and the like where a chain-type strobe light system is installed.

Mode for Carrying Out the Invention

[0012] Hereinafter, the flash lamp core breakage generating device 1 of the present invention (hereinafter also referred to as "core breakage generating device") will be described in detail with reference to the drawings. In FIGS. 1 to 4D, the same members are denoted by the same reference numerals. Note that the embodiments described below show specific examples of the present invention, so the arrangement, functions, numerical values, etc. of the component parts described in the embodiments are merely examples, and the scope of the present invention is not limited or construed by these. Also, in the drawings, basically, component parts such as wiring, screws, and connectors are omitted.

[0013] In a chain - type flash lamp system for aircraft guidance (hereinafter also referred to as "system"), unexpected situations such as non - lighting may occur in the light emitting part, power supply part, control unit, etc. of the flash lamp due to aging deterioration or sudden failures, etc., and these have an important impact on aircraft guidance, so the maintenance of the flash lamp system is important.

[0014] The flash lamp core breakage generating device of the present invention uses a portable and small - sized flash lamp core breakage generating device to check the lighting state of the LEDs arranged in the light emitting part of the flash lamp, thereby performing an abnormality inspection of the controller.

Example

[0015] To facilitate understanding of the present invention, an example of the chain flash lamp system 10 of the present invention will be described with reference to FIG. 1.

[0016] FIG. 1 is a block diagram of the chain flash lamp system 10. As shown in FIG. 1, the system 10 includes flash lamps F1 to F n having light emitting parts A1 to A n and power supply parts B1 to B n , a communication line 70, and a controller 80. In the flash lamps F1 to F n , 、 the light emitting parts A1 to A n are respectively connected to the corresponding power supply parts B1 to B n via cables C1 to C n , and the power supply parts B1 to B n are connected to the controller 80 via the communication line 70.

[0017] The lighting signal transmitted from the controller 80 through the communication line 70 is sent to the power supply parts B1 to B n to light the light emitting parts A1 to A n , and information is fed back from the power supply parts B1 to B n to the controller 80 through the communication line 70.

[0018] In FIG. 1, the arrow AD indicates the approaching direction of the aircraft. To guide the aircraft to the runway, in the flash lamps F1 to F n , the light emitting part A1 is arranged linearly from the entrance direction of the runway to the approaching part of the aircraft, and A n is arranged at the deepest part.

[0019] In the system 10, when the number of sets n of the light emitting part A n and the power supply part B n corresponding to the light emitting part A n is one set, the number of sets n is 3 in FIG. 1, but the number of sets n may be an integer of 2 or more. The number of sets n is the light emitting part A in the chain flash lamp defined for each country in the world nIt is appropriately determined in a form corresponding to the number of sets. Specifically, the number of sets n is from 2 to 30, and in the case of Japan, the number of sets n is 29.

[0020] Power supply units B1 to B n respectively control the lighting of the corresponding light emitting units A1 to A n Also, power supply units B1 to B n receive the lighting signal transmitted from the controller 80, and transmit information such as the lighting status of the light emitting units A1 to A n , power supply units B1 to B n to the controller 80.

[0021] The lighting signal is a signal instructing the light emitting units A1 to A n to emit a flash. Once the light emitting units A1 to A n are lit, in order to maintain the lighting state, the lighting signal usually includes a signal regarding the lighting time of the light emitting units A1 to A n and a extinguishing signal for turning off the lighting of the light emitting units A1 to A n after a certain lighting time. The lighting time is from 0.01 to 50 milliseconds.

[0022] Power supply units B1 to B n receive the lighting signal and light the corresponding light emitting units A1 to A n . Power supply units B1 to B n may be any means capable of lighting the light emitting units A1 to A n , and well-known voltage application means is used.

[0023] Light emitting units A1 to A n have a time condition of sequentially lighting at a predetermined interval T n in the direction from the light emitting unit A1 to the light emitting unit A p . Power supply units B1 to B n operate under the time condition of lighting the light emitting unit A p ×n seconds after receiving the lighting signal. The predetermined interval T n is about 17 milliseconds, but is not limited thereto, and may be set in consideration of the time lag that occurs until the power supply units B1 to B p receive the simultaneously transmitted lighting signal. n ​

[0024] The power wiring (not shown) provided in the system 10 is single-phase three-wire, but it may also be single-phase two-wire. The power supply to the system 10 is usually from a commercial power supply to the power supply units B1 to B n through the power wiring.

[0025] The communication wiring 70 is a wiring that performs two-way communication serving as both input communication wiring and output communication wiring. It functions as the communication wiring 70 for transmitting a lighting signal from the controller 80 to the power supply units B1 to B n and at the same time functions as the output communication wiring 70 for feeding back information from the power supply units B1 to B n to the controller 80. When there are multiple communication wirings 70, one can be used as the input communication wiring and the other can be used as the output communication wiring for feeding back information from the power supply units B1 to B n to the controller 80. Also, for the communication wiring 70, communication wirings capable of data communication such as metal communication cables and optical fiber communication cables are used.

[0026] Next, the lighting method of the light emitting units A1 to A n in the system 10 will be described.

[0027] First, when a lighting signal is transmitted from the controller 80, the power supply units B1 to B n receive the lighting signal and, based on the time condition set for the corresponding light emitting units A1 to A n from the reception of the lighting signal to the power-on of the power supply units B1 to B n , turn on the power of the power supply units B1 to B n and light the corresponding light emitting units A1 to A n . The output of the power supply units B1 to B n is AC200V, but it is not limited to this.

[0028] The number of transmissions of the lighting signal from the controller 80 is one or more. When the number of transmissions is multiple, the controller 80 repeatedly transmits the lighting signal at a predetermined interval T f during the time specified by a user such as a controller for a predetermined interval Tf is based on about 500 milliseconds, but is not limited thereto.

[0029] As a specific example, for the power supply units B1 to B n the time condition is that the power supply units B1 to B p are turned on after T × n seconds from the reception of the lighting signal. When the predetermined time T n is about 17 milliseconds, the light emitting units A1, A2, ···, A p will light up about 17 milliseconds, about 34 milliseconds, ···, about 17 × n milliseconds after the reception of the lighting signal, respectively. n When viewed from the pilot of the aircraft, the light emitting units A1 to A

[0030] will light up sequentially at intervals of about 17 milliseconds along the approach direction of the aircraft (the direction of arrow AD). n n n As described above, the system 10 of this embodiment sequentially lights up the light emitting units A1 to A

[0031] based on the time condition after the power supply units B1 to B n receive the lighting signal transmitted from the controller 80. n n

[0032] The controller 80 may further transmit a light intensity designation signal to the plurality of power supply units B1 to B n simultaneously through the communication wiring 70. In that case, the power supply units B1 to B n receive the light intensity designation signal, and the power supply units B1 to B n light up the light emitting units A1 to A n at the time of power-on so that the light intensity of the light emitting units A1 to A n at the time of power-on specified by the light intensity designation signal becomes the light intensity specified by the light intensity designation signal. The light intensity of the light emitting units A1 to A n at the time of power-on specified by the light intensity designation signal is the peak light intensity of the light emitting units A1 to A

[0033] FIG. 2A is a front view of the light emitting unit A1 in the embodiment, and FIG. 2B is a simplified circuit model of the LED module 90 in the embodiment. Note that the flashlights F1, F2, Fn are all the same including the light emitting parts A1, A2, A n , and the power supply parts B1, B2, B n . Therefore, the embodiment will be described based on the flash lamp F1, the light emitting part A1, and the power supply part B1.

[0034] As shown in FIG. 2A, the light emitting part A1 of the flash lamp F1 is a substantially circular cylindrical body 14, and the side surface has a substantially trapezoidal shape (see FIG. 1). On the side surface of the cylindrical body 14, a substantially U-shaped arm 33 for holding the cylindrical body 14 and a leg part 34 for holding the cylindrical body 14 by being coupled to the bottom of the arm 33 are provided. Inside the cylindrical body 14, a reflector 95 having a circular cross-section and an overall substantially frustoconical shape is disposed. The bottom 96 near the center of the reflector 95 is circular, and on the bottom 96, one substantially rectangular LED module 90 is disposed. The reflector 95 is a light distribution means for efficiently irradiating the irradiation light emitted from the LED module 90 forward.

[0035] In the embodiment, the LED module 90 is shown as being flat and disposed one on the circular part near the center of the light emitting part A1, but a plurality of LED modules 90 may be arranged in parallel or in a matrix near the center or at the periphery. Further, the LED module 90 is not limited to being flat, and may be formed in an appropriate shape such as a convex shape or a concavo-convex shape in the irradiation direction as long as it is a type that irradiates in the front direction.

[0036] Here, the light emitting part A1 and the power supply part B1 constituting the flash lamp F1 will be described.

[0037] As shown in FIG. 2B, each LED module 90 disposed in the light emitting part A1 of the flash lamp F1 is composed of m LEDs 92 in one row. Taking the first row of LED columns as L1, a total of p rows of LED columns L1, L2, L p are arranged in parallel. Each LED 92 emits light, and the LED module 90 emits irradiation light in the front direction when the LEDs 92 disposed in the respective LED columns L1, L2, L p emit light. Specifically, each of the LED columns L1, L2, L pThe number m of LEDs is 1 to 300, preferably 30 to 200, more preferably 50 to 100. The number p of LED columns is 1 to 100, preferably 5 to 50, more preferably 10 to 25. The entire LED module 90 is composed of a maximum of 10,000 to 30,000 LEDs. The number of LEDs in one column and the number of LED columns are not limited to this, and may be increased or decreased as necessary.

[0038] The power supply 50 applies a direct current to a parallel circuit composed of LED columns L1, L2, L p and supplies it to the LED module 90 after converting the alternating current supplied from the power supply unit B1 into an appropriate direct current by A / D conversion.

[0039] FIG. 3 is a schematic diagram showing a state in which the core-breaking generator 1 in the embodiment is installed between the light-emitting part A1 of the flash lamp F1 and the power supply part B1. A connector 20 is arranged at the bottom of the light-emitting part A1, and a connector 30 is arranged at the upper part of the power supply part B1. Usually, the connector 20 and the connector 30 are connected via a cable C1 (see FIG. 1).

[0040] As shown in FIG. 3, a pair of connection ports 40 and 41 are arranged on the upper and lower surfaces which are the surfaces of the main body of the core-breaking generator 1. One of the connection ports 40 can be connected to the connector 20 installed in the light-emitting part A1 by the cable C1, and the other of the connection ports 41 can be connected to the connector 30 arranged on the upper surface of the power supply part B1 by the connection cable 60. The connectors 20, 30 and the connection ports 40, 41 function as sockets for fixing the cable C1 and the connection cable 60 and conducting the current. It is possible to transmit the current sent from the power supply part B1 to the light-emitting part A1 through the connection ports 40 and 41.

[0041] In the embodiment, an example is shown in which the connection port 40 of the core-breaking generator 1 and the connector 20 of the light-emitting part A1 are connected using the cable C1 normally used in the light-emitting part A1. However, two connection cables 60 attached to the core-breaking generator 1 may be used without using the cable C1.

[0042] FIG. 4A is a front view of the flash lamp core-breaking generator 1 in the embodiment, FIG. 4B is a side view thereof, and FIG. 4C is a top view thereof. The flash lamp core-breaking generator 1 of the embodiment is formed from a substantially rectangular main body 5.

[0043] As shown in FIG. 4A, a total of eight switches from S1 to S8 are arranged on the front of the main body 5. Horizontally, switches S1 to S4 are arranged in the upper row, and switches S5 to S8 are arranged in the lower row. Switches S1 to S8 are ON / OFF switches, and switches S1 to S8 are two-pole changeover switches that turn on the power when tilted upward and turn off the power when tilted downward. Also, a pilot lamp composed of a light-emitting element such as an LED that lights up when the power is on and goes out when the power is off may be provided near each of the switches S1 to S8. In addition, connection ports 40 and 41 are installed at the upper and lower parts of the main body 5, respectively. The connection port 40 is electrically connected to the connection port 41 through the switches S1 to S8.

[0044] FIG. 4B shows that switches S4 and S8 are arranged on the front of the substantially cuboid-shaped main body 5, the connection port 40 is arranged on the upper surface, and the connection port 41 is arranged on the bottom surface.

[0045] FIG. 4C shows that the connection port 40 is arranged on the upper surface of the main body 5, and the switches S1 to S4 are arranged on the side surface. The connection ports 40 and 41 have a plurality of and the same number of pinholes (connection parts) 100 that are joined to the terminals of the connection plug (not shown) of the cable C1. The pair of connection ports 40 and 41 each have a plurality of and the same number of connection parts 100, and the plurality of connection parts 100 of each of them are conductively connected in a one-to-one correspondence, and at least a part of them can be turned ON / OFF via the switches S1 to S8 (see FIG. 4A).

[0046] FIG. 4D is a simplified circuit model diagram showing a state in which switches S1 to S8 mounted on the core break generating device 1 in the embodiment are connected in series between LED columns L1 to L8, respectively. The LED columns L1 to L8 of the LED module 90 mounted on the light emitting unit A1 are turned off every time the switches S1 to S8 of the core break generating device 1 are sequentially turned off. When the switch S8 is turned off, the irradiation light emitted from the light emitting unit A1 is halved. The switches S1 to S8 are arranged corresponding to at least a part of the LED columns L1 to L8.

[0047] On the other hand, for the flash lamp abnormality (communication abnormality) of the control unit 80, when eight or more LED columns of the LED columns L1 to L 16 of the LED module 90 mounted on the light emitting unit A1 are turned off, a command is issued. Therefore, among the switches S1 to S8 mounted on the core break generating device 1, communication abnormality is not commanded when the switches S1 to S7 are turned off. Further, if a communication abnormality is commanded from the control unit 80 by turning off the switch S8, it means that the controller 80 is functioning normally.

[0048] However, when a communication abnormality is commanded from the control unit 80 while sequentially turning off the switches S1 to S7 of the core break generating device 1, it means that the controller 80 is abnormal. Also, when the switches S8 are sequentially turned off and no communication abnormality is commanded from the control unit 80, it means that a communication abnormality has occurred in the controller 80. Note that the switches S1 to S8 of the core break generating device 1 increase or decrease according to the number p of LED columns of the LED module 90, so S1 to S p results. In that case, when p / 2 or more (the decimal part of an odd number is rounded down) LED columns of the LED columns L1 to L p of the LED module 90 mounted on the light emitting unit A1 are turned off, a communication abnormality will be commanded from the control unit 80.

[0049] Note that a processed material of a steel plate is used for the main body 5, but in addition to other metal materials such as a stainless steel plate and an aluminum plate, plastic materials such as ABS and PC (polycarbonate) may also be used. Further, the main body 5 preferably has a waterproof and moisture-proof specification so as not to prevent use in rainy days, fog, etc. Further, a handle (not shown) may be attached to the side surface of the main body 5 to further improve portability.

[0050] As described above, the present invention has been described with reference to the embodiments, but the present invention is not limited to the above embodiments. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
