The communication device is configured to transmit and receive the disconnection information by wireless communication or wired communication, and the remaining (n−1) disconnection detection devices and the communication device transmit the disconnection information by wireless communication. It is configured to transmit and receive.
With this configuration, the cost of the entire system and the equipment volume can be reduced from the present level.

Hereinafter, the configuration of the broken position detection device for an air lamp according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 2.
FIG. 1 is a block diagram showing an overall configuration of an aerial light breakage position detecting apparatus according to a first embodiment of the present invention. FIG. 2 is a block diagram showing a configuration of a main part of the broken line position detection device for an air lamp according to the first embodiment of the present invention.

A plurality of lamps 1 (1 ₁ , 1 ₂ , 1 ₃ ,..., 1 _i ,...) Are installed on the airport runway. The aircraft 15 takes off and landing on the runway using the lamp 1. A plurality of hand holes 6 (6 ₁ ,..., 6 _n ,...) Are embedded in the ground of the runway. Inside the handhole 6 are a plurality of wireless disconnection detectors 2 (2 ₁ , 2 ₂ , 2 ₃ ), one power line carrier communication device 4, and a plurality of rubber transformers 5 (5 ₁ , 5 ₂ , 5 ₃ ) are stored. The number of disconnection detecting devices 2 housed in the handhole 6 is normally about 1 to 5, but on average is 3.

  The rubber transformer 5 supplies power supplied from the power line 7 to the lamp device 1. The wireless disconnection detecting device 2 is for monitoring the disconnection of the lamp of the lamp 1, and is disconnected to the power line carrier communication device 4 which is the upper communication unit by the wireless communication 3 in which the disconnection is detected. Notify the wick. The power line carrier communication device 4 receives the wireless communication 3 and transmits disconnection information to the master station 8.

  Inside the power supply station 11, a master station 8 that receives the disconnection information from the power line carrier communication device 4 via the power line 7 and a communication signal for carrying the power line on the AC waveform transmitted through the power line 7 are removed. A bypass filter 9 for power supply and a power supply device 10 for supplying power to the lamp 1 are connected to each other. The power line 7 and the master station 8 are connected by a rubber transformer 5.

  The wireless disconnection detecting device 2 transmits the identification information of the wireless disconnection detecting device 2 by wireless communication 3 while the lamp 1 is supplied with power from the rubber transformer 5. When the lamp in the lamp 1 is disconnected, the wireless disconnection detecting device 2 loses power and consequently the wireless communication 3 disappears. The power line carrier communication device 4 is connected to the wireless disconnection detection device 2 having the identification information by detecting that the transmission of the identification information by the wireless communication 3 from the wireless disconnection detection device 2 is interrupted. It detects that the lamp in the lamp 1 is broken.

  Next, detailed configurations of the wireless disconnection detecting device 2 and the power line carrier communication device 4 housed in the handhole 6 will be described with reference to FIG.

  As shown in FIG. 2, rubber for supplying electric power via a power line 7 to the lamp 1 installed on the road surface of the runway is embedded in the hand hole 6 buried on the roadside of the runway. A transformer 5, a plurality of wireless disconnection detection devices 2, and one power line carrier communication device 4 are accommodated. In addition, since the handhole 6 is not kept airtight, the device accommodated in the inside needs to have a waterproof structure and a structure that can withstand adhesion of mud. In addition, about the connector which connects the electric power line 7, the connector with rubber coating is prescribed | regulated by the lighting 57th of the Ministry of Land, Infrastructure, Transport and Tourism in the domestic airport.

The plurality of wireless disconnection detection devices 2 (2 ₁ , 2 ₂ ) are respectively provided with a power acquisition unit 16 (16 ₁ , 16 ₂ ), a device identification information storage unit 17 (17 ₁ , 17 ₂ ), and wireless transmission. Part 18 (18 ₁ , 18 ₂ ). The power acquisition unit 16 includes, for example, a transformer and an AC-DC converter, and generates DC power of about 10 V from AC power of about 100 V supplied from the power line 7 via the rubber transformer 5. The DC power is supplied as a power source for the wireless transmission unit 18. Unique identification information corresponding to the lamp 1 is stored in the device identification information storage unit 17. For example, when there are 1000 lamps 1, the identification information is a number such as 1-1000. When the lamp 1 is not disconnected, the wireless transmission unit 18 is operated by the power supplied from the rubber transformer 5 and the power acquisition unit 16, and the identification information stored in the identification information storage unit 17 is stored. Then, it is transmitted to the power line carrier communication device 4 by the wireless communication 3. When the lamp 1 is disconnected, the power supply from the power acquisition unit 16 to the wireless transmission unit 18 is stopped, so that the wireless communication 3 is also interrupted.

  Only one power line carrier communication device 4 is provided inside the hand hole 6 with respect to the plurality of wireless disconnection detection devices 2. The power line carrier communication device 4 includes a wireless reception unit 19, a circuit protection unit 20, a power supply acquisition unit 21, and a power line carrier communication unit 22. The wireless receiver 19 receives the wireless communication 3 transmitted by the wireless transmitter 18 and sends the received information to the power line carrier communication unit 22. The circuit protection unit 20 shorts the two power lines when the lamp in the lamp 1 is broken. The circuit protection unit 20 includes, for example, a bypass relay and a processing circuit that detects an overvoltage state due to disconnection of the lamp device 1 and operates the bypass relay, as described in JP-A-11-111472. ing. When the disconnection of the lamp is detected, the processing circuit operates the bypass relay to short-circuit the two power lines that supply power from the rubber transformer 5 to the lamp 1. The power acquisition unit 21 has the same configuration as the power acquisition unit 16 and supplies the obtained DC power to the wireless reception unit 19, the circuit protection unit 20, and the power line carrier communication unit 22. The power line carrier communication unit 22 performs power line carrier communication on the information received from the wireless reception unit 19 to the master station 8 in the power supply station 11.

While the lamp 1 is lit, the power acquisition unit 16 in the wireless disconnection detection device 2 continues to acquire power, and the wireless transmission unit 18 uses the power line carrier system to identify the device identification number of the identification information storage unit 17. The wireless communication unit 19 in the communication device 4 continues to perform wireless communication 3. When the lamp is disconnected, the power acquisition unit 16 loses power supply, so the wireless communication 3 is interrupted, and the power line carrier communication unit 22 is a lamp to which the wireless disconnection detecting device 2 having the disconnected device identification number is attached. It can be determined that the container 1 is disconnected. The position where the power line carrier communication device 4 is attached is between the wireless disconnection detecting device 2 and the rubber transformer 5. This is because when the disconnection occurs, the two power lines are short-circuited in the circuit protection unit 20, and power is supplied from the rubber transformer 5 to the power line carrying system communication device 4.
The number of installed devices is the same as the number of power transformers 4 in one handhole and the number of rubber transformers 5 in the handhole for the wireless disconnection detector 2. For example, when three wireless disconnection detecting devices 2 are accommodated in the hand hole 6, the size of the hand hole 6 is, for example, about 1 m in length, 1 m in width, and 50 cm in height. Therefore, the identification information storage unit 17 and the wireless transmission unit 18 in the wireless disconnection detecting device 2 can be configured by a microchip or a muchip that can transmit identification information of a lamp of several to several tens of bits. The wireless receiver 19 serves as an antenna for reception. Since the wireless communication 3 is a microwave and can be omni-directional, unlike infrared communication, etc., it corresponds to the installation of a flexible device in the handhole 6 and there is some moisture and dirt in the handhole. Even if it exists, the wireless communication 3 is not affected. Also, because the communicable distance is a weak microwave of several tens of centimeters, there is no need for an application for setting up a radio station under the Radio Law, and since it is used in an embedded handhole, it is regarded as a problem of noise There is no obstacle to the application to the airport. Further, the power consumption of the wireless disconnection detecting device 2 can be very small, from several to several tens of milliwatts.
Since the power consumption of the wireless receiver 19 is about several hundred milliwatts, the wireless receiver 19 is installed in the power line carrier communication device 4 by taking the received signal into the microcomputer used by the conventional power line carrier circuit. The increase in power consumption is less than the power consumption reduction effect due to the reduction in the number of power line carrier circuits. For example, in the lighting of the Ministry of Land, Infrastructure, Transport and Tourism, the upper limit of power consumption of the conventional power line carrier system is 10 watts. Assuming that the power consumption of the wireless receiver 19 is 0.5 watt, the power line carrier communication device 4 except for the wireless receiver 19 in the power line carrier communication device 4 is the same as the conventional type. Device 4 will be 9.5 watts. The power consumption of the wireless disconnection detecting device 2 is set to 0.1 watts, for example. In domestic airports, 1 to 5 rubber transformers are installed in one handhole depending on the application. If there are an average of 3 rubber transformers installed in the handhole,
(Power consumption of power line carrier communication device 4 x number of units + Power consumption of wireless disconnection detection device 2 x number of units)
÷ (conventional integrated power consumption x number of units)
= (9.5 × 1 + 0.1 × 3) ÷ (9.0 × 3) ≈0.362
Thus, the power consumption can be reduced to 36% of the conventional one. In the case where 1000 lamps are installed on the runway, conventionally, 9 kilowatts of electric power is consumed, but in the system of this embodiment, the power consumption can be reduced to about 3.3 kilowatts.

Next, cost will be described. A conventional power line carrier communication device is assumed to be 100,000 yen, for example. The antenna of the wireless receiver 19 is set to 20,000 yen, and the cost of incorporating the antenna into the conventional type is considered to be included in the antenna fee. The microchip or mu chip of the identification information storage unit 17 and the wireless transmission unit 18 in the wireless disconnection detection device 2 is inexpensive, but the power acquisition unit 16 and the price of the casing of the wireless disconnection detection device 2 are considered. Assuming that the price of the wireless disconnection detecting device 2 is 20,000 yen, when three rubber transformers are installed in one handhole,
(Price x number of power line communication system communication device 4 + price of wireless disconnection detection device 2 x number)
÷ (conventional unit price x number)
= {(10 + 2) × 1 + 2 × 3} ÷ (10 × 3) ≈0.6
Thus, the manufacturing cost can be reduced to 60% of the conventional cost.

Next, the volume of the device will be described. In the lighting 276 of the Ministry of Land, Infrastructure, Transport and Tourism, the external shape of the slave station of the disconnection position detecting device is defined as 150 mm × 200 mm × 90 mm or less. The size of the device in which the conventional disconnection detection unit and the power line carrier communication unit are housed in the same casing is set to 150 mm × 200 mm × 90 mm, similarly to this specification. In addition, the communication frequency of the microchip or the muchip that performs the wireless communication 3 is a gigahertz band, and the wireless receiver 19 is a planar antenna having a side of several centimeters and can be attached to the surface of the casing. Is set to 150 mm × 200 mm × 90 mm, which is the same as the conventional size. Since the identification information unit storage unit 17 and the wireless transmission unit 18 in the wireless disconnection detection device 2 are microchips or muchips, they are large in size, and the power acquisition unit 16 also requires power required for the microchips or muchips. Therefore, it takes up less volume than a chip. However, since the size of the connector for connecting the power line is required for the housing, the size of the wireless disconnection detecting device 2 is set to 30 mm × 30 mm × 60 mm. When three rubber transformers are installed in one handhole (volume of power line carrier communication device 4 x number of units + volume of wireless disconnection detector 2 x number of units)
÷ (conventional integrated volume x number)
= {(150 × 200 × 90) × 1 + (30 × 30 × 60) × 3}
÷ {(150 × 200 × 90) × 3}
≒ 0.353
Thus, the volume of the equipment is 35% of the conventional volume, and the volume can be reduced.

  Further, in the conventional apparatus, the cross-sectional core detector and the power line communication unit had to replace the entire apparatus even if the fault is one of either because it together, separated in the manner of this embodiment Since it has a structure, it is only necessary to replace the failed part, so that the cost at the time of failure can be reduced. In addition, since the wireless disconnection detection device 2 occupying a large number in the handhole is less expensive than the power line carrier communication device 4, it is possible to maintain maintainability by separating the disconnection detection unit and the power line carrier communication unit. Economic efficiency can be improved.

  The number of power line carrier communication devices 4 provided in one handhole 6 may be two or more. When one handhole 6 includes five wireless disconnection detection devices 2 and two power line carrier communication devices 4, the first power line carrier communication device 4 causes three wireless disconnections. It is also possible to receive a signal from the detection device 2 and receive signals from the remaining two wireless disconnection detection devices 2 by the second power line carrier communication device 4. In any case, a plurality of wireless disconnection detection devices 2 are made to correspond to one power line carrier communication device 4.

  As described above, according to the present embodiment, the manufacturing cost can be reduced as compared with the conventional one. In addition, the volume of the device can be made smaller than before. Furthermore, the power consumption can be made lower than before. In addition, maintainability and economy can be improved.

Next, with reference to FIG. 3, the configuration of the airline breakage position detection device according to the second embodiment of the present invention will be described.
FIG. 3 is a block diagram showing a main configuration of an aerial light breakage position detection device according to the second embodiment of the present invention. The same reference numerals as those in FIG. 2 indicate the same parts.

In the present embodiment, the lighting device 1 ₁ the power line carrier method communication device 4 is connected, without connecting the wireless sectional core detector 2, lighting devices in the circuit protection unit 23 of the power line carrier method communication device 4 11 detects the disconnection of the lamp in the lamp 11 and transmits information that the disconnection has occurred to the power line carrier communication unit 22 by wired communication. For lamp unit 1 ₂ in which the power line carrier method communication device 4 is not connected, similarly to the embodiment shown in FIG. 2, to connect the wireless sectional core detector 2, the wireless reception of power line carrier method communication device 4 The unit 19 receives the wireless communication 3 from the wireless disconnection detecting device 2 and transmits the received information to the power line carrier communication unit 22.

  The circuit protection unit 23 short-circuits the two power lines when the lamp in the lamp 11 is broken, and information that the power is supplied from the rubber transformer 5 to the power line carrier communication device 4 and is broken. Is transmitted to the power line carrier communication unit 22. For the disconnection information, for example, a high level signal is output when disconnection is performed, and a low level signal is output when disconnection is not performed. As described above, since the circuit protection unit 23 includes the protection relay and the processing circuit, when the processing circuit detects disconnection, the protection relay is operated and a high level signal is output.

  As described above, according to the present embodiment, the manufacturing cost can be reduced as compared with the conventional one. In addition, the volume of the device can be made smaller than before. Furthermore, the power consumption can be made lower than before. In addition, maintainability and economy can be improved. Furthermore, since it is not necessary to connect the wireless disconnection detecting device 2 to the lamp 1 to which the power line carrier communication device 4 is connected, the number of storage devices in the handhole 6 can be reduced.

Next, with reference to FIG. 4, the configuration of an aerial light breakage position detection device according to a third embodiment of the present invention will be described.
FIG. 4 is a block diagram showing a configuration of a main part of an incandescent position detection device for an air lamp according to a third embodiment of the present invention. The same reference numerals as those in FIG. 2 indicate the same parts.

In the present embodiment, the lighting device 1 ₁ the power line carrier method communication device 4 is connected, the power acquisition unit 16 functioning as a wireless disconnection core position detector 2 in the housing of the power line carrier method communication device 4, The devices of the identification information storage unit 17 and the wireless transmission unit 18 are stored. Since the wireless communication 3 is a microwave, depending on the frequency used, noise-resistant processing such as covering the microcomputer used in the power line carrier communication unit 22 with an aluminum plate is required. There is no problem in taking in the wireless disconnection detecting device 2.

  As described above, according to the present embodiment, the manufacturing cost can be reduced as compared with the conventional one. In addition, the volume of the device can be made smaller than before. Furthermore, the power consumption can be made lower than before. In addition, maintainability and economy can be improved. Furthermore, since it is not necessary to connect the wireless disconnection detecting device 2 to the lamp 1 to which the power line carrier communication device 4 is connected, the number of storage devices in the handhole 6 can be reduced.

Next, with reference to FIG. 5, the configuration of an aerial light breakage position detection device according to a fourth embodiment of the present invention will be described.
FIG. 5 is a block diagram showing a main configuration of an aerial light breakage position detecting device according to a fourth embodiment of the present invention. The same reference numerals as those in FIG. 2 indicate the same parts.

  In the present embodiment, the disconnection detection unit 2 and the wireless communication unit 3 use the same wireless disconnection detection device 2 and the wireless reception unit 19 as those shown in the embodiments of FIGS. However, transmission of information to the power supply station 11 is performed by the signal line communication device 25 using the signal line 24 such as a device net by the communication unit 26. The signal line 24 includes a power line that supplies power for operating the communication unit 26 and the wireless reception unit 19. Further, the master station 8 in the power station 11 is not connected to the power line 7, but is connected to the signal line 24, and information on the disconnection of the lamp is transmitted by a communication method such as a device net.

  As described above, according to the present embodiment, the manufacturing cost can be reduced as compared with the conventional one. In addition, the volume of the device can be made smaller than before. Furthermore, the power consumption can be made lower than before. In addition, maintainability and economy can be improved. Furthermore, when the communication terminal 25 using the signal line 24 is installed in the handhole 6, it is not necessary to connect the signal line type communication device 25 to the power line 7 that supplies power to the lamp in the lamp 1 by wire. Therefore, complicated wiring in the hand hole 6 is not necessary. Further, even when abnormal fluctuations in the current and voltage supplied to the power line 7 occur, it is only the relatively inexpensive wireless disconnection detector 2 that may be damaged, and the relatively expensive signal line system. The influence on the communication device 25 can be eliminated.

Next, the configuration of the disconnection information sending service system using the aerial lamp disconnection position detection device according to each embodiment of the present invention will be described with reference to FIGS.
