  The present invention relates to an illumination lamp lighting state detection device capable of detecting a lighting state or a non-lighting state of an illumination lamp such as a street lamp provided over a wide area such as a road, a park, or a river.

  In general, a large number of road lamps, park lamps, and lamps provided along rivers are provided over a wide area. When such an illumination lamp breaks out, it is necessary to quickly detect this and take countermeasures such as replacement.

  In order to detect the lamp burnout of a large number of illuminating lamps scattered in a wide area as described above, conventionally, a traveling vehicle is run at night and confirmed visually. However, this requires manpower for patrol. In order to prevent oversight, the traveling vehicle needs to travel at a relatively low speed. For this reason, there was a possibility of inducing an accident due to traffic congestion or traffic concentration.

  As an improvement plan for detecting non-lighting of the illuminating lamp by this patrol vehicle, a sensor for detecting the malfunction of the illuminating lamp is provided on the illuminating lamp side, and a detection signal is transmitted by this sensor, and this is detected on the patrol vehicle side. Thus, it has been proposed to detect the lighting / non-lighting state of the illuminating lamp (see, for example, Patent Document 1 and Patent Document 2).

  In the former proposed above, each illumination lamp is provided with detection means for detecting normality and abnormality of the operation, and the detection result by this detection means is transmitted wirelessly together with a code set for each of the illumination lamps. The transmitted data is received by a moving means such as a traveling vehicle, thereby detecting the lamp burnout.

Further, in the latter of the above proposals, on the side of the illuminating lamp, a detecting means for detecting the non-lighting state is provided, and a transmitting means for transmitting an infrared signal based on a result of the detecting means is provided, and transmitted from the transmitting means. The infrared signal is received by a receiving means attached to a traveling vehicle traveling on the road.

  However, according to any of the above proposals, it is necessary to provide sensors, wireless transmitters, infrared transmitters, etc. for each of a large number of illumination lamps, and to provide a facility for receiving signals from the illumination lamp side on the traveling vehicle side. For this reason, equipment costs increase, and a lot of labor is required for maintenance and management, and the trouble of running a traveling vehicle is the same as before.

  An object of the present invention is to provide an illumination lamp lighting state detection device that can detect a lighting state or a non-lighting state of an illumination lamp without installing a sensor on the illumination lamp or traveling a patrol vehicle at night. .

And an image processing means for detecting a lighting state or a non-lighting state for each of the illumination lamps.

  Further, in the present invention, the facility information that associates the installation location of the illuminating lamp with the type of the illuminating lamp installed in the installation location, and the facility capable of detecting the type of the illuminating lamp detected as non-lighting The structure provided with the exchange means may be sufficient.

  Furthermore, in the present invention, in addition to the correspondence relationship between the installation location of the illumination lamp and the illumination lamp installed at the installation location, the facility information includes the type of appliance that supplies power to each illumination lamp. The configuration may be set so as to correspond to the illumination lamp.

  According to the present invention, satellites or aerial photographs obtained online or offline are mapped on a GIS (Geographic Information System), and photographs of latitudes and longitudes around lighting facilities in which predetermined information is registered in advance are processed. Accordingly, it is possible to easily detect the lighting state or non-lighting state of a large number of illumination lamps scattered over a wide range.

  Hereinafter, an embodiment of a lighting lamp lighting state detection apparatus according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing the overall configuration of a lighting state detection apparatus according to this embodiment. This lighting state detection device detects lighting states or non-lighting states of a large number of illuminating lamps installed in a wide area, such as a road lighting facility. In this apparatus, a lighting state of an illumination lamp on the ground (for example, described as an expressway) is detected using a satellite photograph obtained by photographing the ground from an artificial satellite or an aerial photograph obtained by photographing the ground from an aircraft. In other words, in recent years, satellite photographs and aerial photographs have become more precise, and satellite photographs also have a ground resolution of 2.5 m (ground resolution represents a measure of the physical size of the ground that can be identified in an image). What you have has been put to practical use. The present invention uses such high-definition photographic information.

  In FIG. 1, reference numeral 1 denotes an input device, which is used for registering satellite photographs or aerial photographs offline. That is, the input device 1 inputs photographic information obtained by photographing a detection target portion from the sky from an artificial satellite or aircraft, and the photographic information is input to the satellite or aerial photograph storage unit 4 (photo information storage means) via the input processing unit 3. For example). When a satellite photograph or aerial photograph is registered online, it is received by the online receiving unit 2 and stored in the satellite or aerial photograph storage unit 4 via the input processing unit 3.

  Reference numeral 5 denotes a GIS (Geographic Information System) data section, which holds map information. Reference numeral 6 denotes a first mapping processing unit that maps GIS information and photograph information obtained by a satellite photograph or an aerial photograph (hereinafter, proceeded as a satellite photograph). The first mapping processing unit 6 matches the photograph information obtained by photographing the detection target portion from the sky and the map information of the ground portion corresponding to the photograph information together with the scale and the latitude / longitude. That is, the first mapping processing unit 6 performs a superimposing process on the photo information stored in the satellite or aerial photo storage unit 4 and the GIS information in the GIS data unit 5.

  Reference numeral 7 denotes an equipment information section (an example of map information storage means) in which equipment information such as lighting equipment, for example, an installation location of an illuminating lamp is set in advance by latitude / longitude information. Reference numeral 8 denotes a second mapping processing unit that maps the GIS information and the installation location information of the illuminating lamp set in the facility information unit 7. This 2nd mapping process part 8 maps the installation place of an illumination light to the map information of the ground part used as a detection target based on the latitude and the lightness information preset as equipment information. That is, the second mapping processing unit 8 performs a superimposition process of the facility information stored in the facility information unit 7 such as the installation position of the illumination lamp and the map information of the GIS data unit 5.

  The facility information includes the type of appliance (for example, a ballast) that supplies power to each illumination light, in addition to the correspondence between the location of the illumination light and the illumination light installed at the installation location. Suppose that it is set in correspondence with the illumination lamp.

  Reference numeral 9 denotes an image processing unit, 10 denotes a lighting detection processing unit, and 11 denotes a non-lighting detection processing unit. The image processing unit 9 inputs the image information processed by the first mapping processing unit 6 and the image information processed by the second mapping processing unit 8, that is, GIS information, photographic information, and facility information. And image processing. The lighting detection processing unit 10 extracts a lighting lamp in a lighting state from the superimposed image information, and detects which lighting lamp is lit. The non-lighting detection processing unit 11 extracts an unlit lighting lamp from the superimposed image information, and detects which lighting lamp is unlit.

  That is, the image processing means 100 matches the photographic information such as satellite photographs, the map information by the GIS system, and the position information of the illuminating lamp, and the illuminating lamp lighting state or non-lighting state on the photographic information, The lighting state or the non-lighting state for each illumination light is detected in association with the position of the illumination light set in the map information.

  Reference numeral 12 denotes a processing unit for comparison with equipment information used as equipment exchange means. The comparison processing unit 12 uses the facility information in which the installation location of the illuminating lamp and the type of the illuminating lamp installed at the installation location or the type of the power supply device are associated with each other, The type or type of power supply device corresponding to the illumination or the like is detected so that the replacement member can be easily grasped.

  Reference numeral 13 denotes a display processing unit, which displays and outputs the result of the lighting detection processing unit 10 and the result of the non-lighting detection processing unit 11, and the replacement member information obtained by comparison with the facility information by the comparison processing unit 12. .

  Next, the operation will be described using the flowchart of FIG. In FIG. 2, first, it is determined whether or not equipment information such as an illumination lamp is registered (S1). Equipment information includes latitude / longitude information of lighting, KP information (information about kilopoints ... roads (national roads, prefectural roads, highways, etc.), rivers, etc., from a reference point (for example, the start of a national road if it is a national road) Information indicating how many kilometers it is), vertical line information (upline / downline information), luminaire type and model number, installation year, replacement period, preventive replacement schedule, power supply system, etc. It is. If the facility information is not registered, the facility information such as the lighting facility is registered (S2), and the mapping process between the GIS information and the facility information is performed (S3).

  If the facility information is registered, the satellite photograph or the aerial photograph is taken in (S4). Next, the map information (GIS data) corresponding to the photographing target portion of the captured photo information is read (S5). Then, the mapping process between these GIS data and satellite photograph or aerial photograph is performed automatically or manually (S6). In addition, the latitude / lightness information of the illumination lamp targeted for image processing is extracted from the facility information (S7).

  FIG. 3 is a diagram showing this mapping image. In FIG. 3, reference numeral 33 denotes a satellite photograph obtained by photographing a ground portion including a road to be detected, and is assumed to have a high definition having a ground resolution of 2.5 m, for example. In the satellite photograph 33, it is possible to identify whether each of the illuminating lamps provided along the road is in a lighting state or a non-lighting state. In the figure, black circles indicate lighting lamp lighting locations, and cross marks indicate lighting lamp non-lighting locations. This photographic information is mapped onto the corresponding map by the first mapping processing unit 6 in FIG.

  Reference numeral 31 denotes map information based on the GIS system, which is information on an area corresponding to the photographing part. 32 is equipment information such as lighting equipment, and the position of each illuminating lamp is set as latitude / longitude information. The facility information 32 and the map information 31 are subjected to mapping processing by the second mapping processing unit 8 in FIG.

  The above-described information mapped in this manner is superimposed and processed by the image processing unit 9 in FIG. The image processing result is held in a storage unit (not shown) (S8). That is, the latitude / longitude information to be image-processed is extracted from the facility information in S7 described above, and image processing (such as comparison of brightness with the surroundings) is performed on the peripheral portions of the latitude / longitude information extracted for the mapping data in S6. Stores processing results. Next, the image processing result and the facility information 32 (illumination lamp position, etc.) are compared, and a lighting location and a non-lighting location are output (S9).

  Next, from the unlit state of the illuminating lamp, a determination process is performed to determine whether the cause of the unlit is a lamp burnout or a failure of the power supply unit (S10). Usually, the power supply unit of the illuminating lamp is grouped in units of several tens of illuminating lamps. If all the lamps of the entire group are turned off, it means that the failure of the power supply unit is not a lamp out of the illuminating lamp. Determined.

  In addition, when the illuminating lamp is not turned on in units of two, it is determined that either the lamp of the illuminating lamp itself has run out or the power supply apparatus has failed. Usually, the discharge lamp etc. are used for the illuminating lamp, and a power supply device such as a ballast is required. This power supply device such as a ballast is used in combination with one ballast for two illumination lamps from the viewpoint of economy. In this case, when a power supply device such as a ballast breaks down, the two illumination lamps connected to the power supply device are not lit. Further, when one illuminating lamp is not lit due to lamp breakage, since the two illuminating lamps are connected in series to the power supply device, the other illuminating lamp is also unlit. Therefore, as described above, when the illumination lamps are not turned on in units of two, it is determined that either the lamp of the illumination lamp itself has run out or the power supply apparatus has failed.

  That is, it can be determined from the non-lighting location and the number of non-lighting whether the cause of the non-lighting is a failure on the power supply side, a lamp failure of the illumination lamp itself, or a failure of the power supply apparatus.

  Thus, in the case of a failure of the power supply unit according to the result of determining the cause of the non-lighting, bring the corresponding replacement member etc. to perform the failure recovery work for the power supply unit, and the illumination lamp itself or its illumination In the event of a failure of a power supply such as a ballast for the lamp, carry out the replacement work by bringing the relevant replacement member to the site. In this case, the member information necessary for the exchange is extracted from the facility information to cope with it (S11). For example, by displaying the extracted replacement member, the worker can appropriately work without making a mistake in the replacement member carried on site. That is, since the illuminating lamp that is not lit can be identified, the replacement member corresponding to the identified illuminating lamp can be extracted from the facility information and dealt with.

  In general, power supply devices such as lighting lamps and ballasts are often used in a mixture of products from various manufacturers, and some of them are not compatible. Even in such a case, as described above, as the facility information, the correspondence between the installation location of the illumination lamp and the illumination lamp installed at this installation location, the type of appliance that supplies power to each illumination lamp, and the power supply Since the components of the supply unit are set so as to correspond to the illuminating lamps respectively, it is possible to extract and replace an appropriate replacement member by specifying a non-lighting location.

  The above explanation was given for lighting equipment provided along the road, but in addition to the lighting lights managed by such road operators, etc., the lighting equipment such as parks and rivers can be implemented in the same way. it can. In other words, it was necessary to check the lighting of parks and rivers by means other than patrol vehicles such as walking at night, but without any labor, all installed outdoors such as parks and rivers. It can be applied to the detection of the lighting state or non-lighting state of the illumination lamp.

  According to the present invention, since it is possible to detect a lamp break without going to a place where an illuminating lamp is installed, it is possible to save labor. Since there is no need to install a sensor device or the like on the illuminating lamp, the initial cost and running cost can be reduced. It is possible to avoid the occurrence of traffic congestion that has occurred due to low-speed traveling of patrol vehicles. Since power is supplied to a plurality of lighting lamps from the power supply unit, there was a case where it was determined that the power supply unit failure was out of the lamp of the lighting lamp, but it is also possible to determine lamp failure and power supply unit failure, Appropriate replacement member information can be provided, and erroneous recognition of the replacement member or missing parts can be prevented after the start of replacement work.

It is a block diagram which shows one Embodiment of the lighting state detection apparatus of the illuminating lamp concerning this invention. It is a flowchart explaining the example of 1 operation | movement of the lighting condition detection apparatus of the illuminating lamp concerning this invention. It is a figure showing the mapping image of the photograph information in this invention, GIS information, and equipment information.
