In other words, the range where one of the local servers 41,..., 4n (see FIG. 1) is installed may be the section or a predetermined range within the section.

  As shown in FIG. 4A, the screen of the maintenance department display device 71 includes a lamp lamp for each lamp replacement plan, for example, for each road type and section type, as shown in FIG. Exchange date and time (○ month × day 10:00 to 12:00, etc.), replacement target illumination lamp (illumination lamp 1-A5, illumination lamp 1-A6, illumination lamp 1-A7, illumination lamp 1-A8, etc.) are displayed. It is supposed to be. Although not shown in the figure, the expected lamp life, lamp replacement cost, previous lamp replacement date, and the like are also displayed.

  On the screen of the manufacturer's display device 71, as shown in FIG. 5, for example, the type of road, the type of section, the number of lights not lit, the number of remaining lifetimes within 60 days, etc. are displayed. It is. Although not shown, the lamp imaging device 3 is also intended for a manufacturer of a lamp imaging device different from the manufacturer of the illumination lamp, for example, for an after-sales service (for example, a road) , Type of section, installed lighting for each section), and the type and model name correspondence table of the lamp imaging device, etc. can be displayed.

  In FIGS. 4 (a), 4 (b), and 5, in the case of small roads or buildings such as parks, bridges, buildings, etc., road names, park names, bridge names, building names However, it is not always necessary to display the section.

  Next, the function in which the lighting state determination unit 33 determines the lighting state of the corresponding illumination lamp (at least two types of states of lighting or non-lighting) will be described in detail.

  FIG. 6 shows an example of an equivalent screen of the discrimination reference image data stored in advance in the reference image storage unit 331 (see FIG. 2) of the lamp imaging device 3, and FIG. FIG. 6B shows an example of the reference equivalent screen 13 of the reference image data for determining the non-lighting state of the lamp body 12 attached to the front end portion of FIG. FIG. 6C shows an example of the reference equivalent screen 15 of the discrimination reference image data of the lamp body 12 in the insufficient illuminance state.

  In addition, the non-lighting state determination reference image data, the lighting state determination reference image data, and the illuminance insufficient state determination reference image data are the reference equivalent screens 13, 14, 15 respectively. Are the same shape and size, and the size and position of the support column 11 and the size and position of the lamp body 12 in the reference equivalent screens 13, 14, and 15 are the same. The reference equivalent screens 13, 14, and 15 are data having the same number of pixels.

  On the other hand, an equivalent screen (image data) of the imaging information (image data) captured by the image imaging unit 31 (see FIG. 2) of the lamp imaging device 3 and temporarily stored in the captured image storage unit 32. (Hereinafter referred to as “imaging equivalent screen”) has the same shape and the same size as each of the reference equivalent screens 13, 14 and 15, and the same number of pixels as each of the reference equivalent screens 13, 14 and 15. Furthermore, the size and position of the column 11 in the imaging equivalent screen and the size and position of the lamp body 12 are also the size and position of the column 11 in each of the reference equivalent screens 13, 14, and 15. The lamp body 12 is adjusted to have the same size and position.

  Accordingly, the image comparison unit 332 of the lamp imaging device 3 captures the imaging information (image data) that is captured by the image imaging unit 31 (see FIG. 2) and temporarily stored in the captured image storage unit 32. If the image-equivalent equivalent screen of (-)) coincides with the reference equivalent screen 13 of the non-lighting state determination reference image data, it is determined that the corresponding illumination lamp is not lighted, and the lighting state determination reference image If it matches the reference equivalent screen 14 of the data, it is determined that the corresponding illumination lamp is lit, and if it matches the reference equivalent screen 15 of the discrimination reference image data for the state of insufficient illuminance, the response is made. Judge that the lamp is insufficient in illuminance.

  That is, the image comparison unit 332 of the lamp imaging device 3 captures the imaging information (image data) that is captured by the image imaging unit 31 (see FIG. 2) and temporarily stored in the captured image storage unit 32. The corresponding illumination lamp is not turned on if the data matches the determination reference image data in the non-lighted state stored in the reference image storage unit 331 (see FIG. 2) of the lamp imaging device 3 If it matches the discrimination reference image data of the lighting state stored in the reference image storage unit 331, it is determined that the corresponding illumination lamp is lit, and the reference image storage unit If the illuminance deficient state discriminating reference image data stored in 331 matches the corresponding illumination light, it is determined that the illuminance is insufficient. In addition, if a plurality of types of discrimination reference image data for the state of insufficient illuminance are prepared, the level of insufficient illuminance can be detected, and the time until reaching the unlit state can be predicted. Lamp replacement can be implemented systematically.

  In addition, the image comparison unit 332 of the lamp imaging device 3 captures imaging information (image data) that is captured by the image imaging unit 31 (see FIG. 2) and temporarily stored in the captured image storage unit 32. -)), The non-lighting state determination reference image data, the lighting state determination reference image data stored in the reference image storage unit 331 (see FIG. 2) of the lamp imaging device 3, If it does not coincide with any of the discrimination reference image data in the insufficient illuminance state, the next discrimination opportunity is awaited without producing a discrimination result.

  In addition, the lamp imaging device 3 makes the above determinations accurately by comparing the illuminating lamp main body 12 and the background image 1B by image recognition even in bad weather such as rain or fog.

  Note that the illuminance deficient state is not unique, unlike the non-illuminated state and the lit state, and therefore the detection of the illuminance deficient state is not sufficiently accurate. Accordingly, the image comparison unit 332 of the lamp imaging device 3 captures the imaging information (image data) that is captured by the image imaging unit 31 (see FIG. 2) and temporarily stored in the captured image storage unit 32. -) Of the non-lighting state determination reference image data and the lighting state determination reference image data stored in the reference image storage unit 331 (see FIG. 2) of the lamp imaging device 3. You may make it discriminate | determine from the said illumination intensity deficient state when it does not correspond with any.

  Next, as described above, the imaging information (image data) obtained by imaging the illumination lamp (lamp) by the image imaging unit 31 (see FIG. 2) of the lamp imaging device 3 and temporarily storing it in the captured image storage unit 32. ) Of the imaging equivalent screen is adjusted to the same shape and the same size as the reference equivalent screens 13, 14, and 15, and the size and position of the column 11 in the imaging equivalent screen and the lamp body 12 are adjusted. The size and position are also adjusted to be the same as the size and position of the column 11 and the size and position of the lamp body 12 on each of the reference equivalent screens 13, 14, 15. The principle will be described with reference to FIGS.

  7 and 8, the lamp imaging device 3 is attached to the column 11 of the illumination lamp to be imaged so as to be positioned below the illumination lamp to be imaged. Therefore, the lamp imaging device 3 is attached to the lamp imaging device 3 from below. The example in the case of imaging the illumination lamp of the imaging object above is shown.

  In FIG. 7, an image capturing window 361 facing the imaging surface of the built-in image imaging unit 31 and facing the illumination lamp to be imaged is formed on the upper surface of the housing 36 of the lamp imaging device 3, and the first side is located on the side surface. The adjustment knob 362 and the second adjustment knob 363 are provided, and a finder-364 is detachably attached to a side surface different from the first and second adjustment knobs 362 and 363.

  The finder-364 has a viewing window 3641 at one end and an objective window 3642 corresponding to the illumination lamp to be imaged at multiple ends. In addition to the image capturing unit 31, the housing 36 is not illustrated, but the captured image storage unit 32, the lighting state determination unit 33, the lamp monitoring function unit 34, and the like illustrated in FIG. A communication means unit 35 is also incorporated.

  When the lamp image pickup device 3 is attached to the column 11 of the illumination lamp to be imaged, the lamp image pickup device is usually set before the position adjustment of the lamp image pickup device 3 as shown in FIG. The image pickup area 14a of the third image pickup unit 31 includes a reference equivalent screen 14 (FIG. 6B) of the discrimination reference image data stored in the reference image storage unit 331 (see FIG. 2) and the description thereof. 2) and is not in a predetermined position.

  Therefore, in FIG. 7, while confirming the position of the illumination lamp to be imaged from the viewing window 3641 of the finder-364, first, the housing 36 of the lamp imaging device 3 is moved by turning the first adjustment knob 362, for example. It rotates in the circumferential direction (direction of arrow α) around the illumination lamp column 11 to be imaged. That is, the first stage adjustment is performed. As a result of the first stage adjustment, the imaging area 14a of the image imaging unit 31 is one-dimensionally shifted from the reference equivalent screen 14 of the discrimination reference image data as shown in FIG. 8B.

  Next, in FIG. 7, the image capturing unit 31 in the housing 36 is turned by turning the second adjustment knob 363 while confirming the position of the illumination light to be imaged from the viewing window 3641 of the finder-364. Is rotated in the direction of arrow β within a plane that is perpendicular to the rotation direction (direction of arrow α) in the adjustment of the first stage and includes the center line of the column 11. That is, the second stage adjustment is performed. By this second stage adjustment, the imaging region 14a of the image imaging unit 31 in FIG. 8B is moved in the direction of the arrow β, and as shown in FIG. 8C, the reference of the discrimination reference image data. It matches the equivalent screen 14.

  Only by adjusting the first and second stages, the sizes of the lamp body 12 and the column 11 match between the image captured by the image capturing unit 31 and the reference equivalent screen of the discrimination reference image data. In this case, the size of the captured image is adjusted by the adjustment lens of the image capturing unit 31 itself so as to match. That is, the third stage adjustment is performed.

  By performing the first to third adjustments as described above, the imaging information (image data) temporarily stored in the captured image storage unit 32 and the reference image storage unit 331 are stored in advance. Is compared with the discrimination reference image data stored in the image comparison unit 332 by image recognition, the lighting state of the corresponding illumination lamp can be accurately and accurately discriminated.

  Further, as is apparent from FIG. 8, the light sensor (illuminance sensor) described above is used because the illumination light for the sun and night work does not enter the limited imaging region 14a of the image capturing unit 31. As in the case of the conventional patrol car system, there is almost no malfunction caused by extraneous light other than the light of the light to be monitored, such as sunlight or light for night construction.

  Further, if the lamp imaging device 3 is attached to the tip of the support column 11 so that the image imaging unit 31 images the lower illumination lamp, it is possible to almost eliminate the possibility of imaging the light source of the extraneous light. In addition, it is possible to reduce or eliminate abnormal light in the background image by performing image processing on the background image. In this case, it is possible to further improve the accuracy of determining the lighting state of the corresponding illumination lamp. .

  In addition, in order to reduce the probability that the image capturing unit 31 captures a light source of external light, the area occupied by the lamp body 12 to be imaged with respect to the area of the imaging region 14a should be within a fraction. preferable. That is, when the area occupied by the lamp main body 12 to be imaged with respect to the area of the imaging region 14a is, for example, 1/100, the image imaging unit 31 captures the light source of the external light, for example, 1/3. The probability of doing is lowered. However, when the background image 1B is eliminated by setting the area occupied by the lamp body 12 to be imaged to the area of the imaging region 14a to 1/1, the lamp body 12 and the background image 1B are compared by image recognition. Since it becomes impossible to increase the accuracy of lighting state determination in the case of bad weather such as rainy weather or fog as described above, it is difficult to increase the accuracy of the lighting of the imaging target with respect to the area of the imaging region 14a. Most preferably, the area occupied by the main body 12 exceeds 1/1 and falls within a fraction.

  Further, as described above, although the area occupied by the lamp main body 12 to be imaged with respect to the area of the imaging region 14a is more preferably less than 1/1 and within a fraction, the image imaging unit 31. The amount of information of the image captured by the camera is larger than that of the conventional patrol vehicle system using the above-described optical sensor (illuminance sensor), but in Embodiment 1 of the present invention, as shown in FIG. Is provided with a lighting state discriminating unit 33 in the lamp imaging device 3 and communicates only information on the lighting state discrimination result (information that is in a lighting state, information that is in a non-lighting state, information that is in a state of insufficient illuminance). Since it is transmitted from the means unit 35, for example, the amount of information for wirelessly transmitting (transmitting with the radio wave 8) the lighting state determination information from the other lamp imaging device received in FIG. Local - it is possible to reduce the amount of information is small communication load to be transmitted to the server 41, the b - Khalsa - server 41 and the supervising service - even if the bus 6 to the low function small capacity becomes possible lighting condition monitoring.

  As described above, in the first embodiment of the present invention, a large number of illumination lamps 1A11, 1A12, 1A13,... 1An1, arranged on both sides A and B of the highway 2 at intervals. 1 An 2, 1 An 3, 1 B 11, 1 B 12,... 1 Bn 1, 1 Bn 2 are each provided with a light sensor and a relay transmission / reception function. 3 An 1, 3 A 12, 3 A 13,. ... 3Bn1 and 3Bn2 are provided, and each lamp imaging device transmits / receives wireless communication while relaying the lighting state information of the corresponding illumination lamp, and the local local server 41, ... 4n on the roadside The integrated server 6 collects the lighting state information of each corresponding illuminating lamp and the lighting server 6 collects the lighting state information of each illuminating lamp collected by each local server 41... 4 n via the network 5. collection The monitoring device 7 accesses the central server 6 and manages the lighting state of the lighting lamp in the management department based on the lighting state information of the lighting lamp, and the maintenance service of the lighting lamp in the maintenance department, It is possible to manage the number of unlit lamps at the manufacturer of the lamp. Therefore, the abnormality of the light that occurred immediately after the patrol officer's patrol cannot be detected until the next patrol, the inconvenience that the traveling of the patrol car may impede the traffic, the light that occurred immediately after the patrol car traveled The problem that the abnormality cannot be found until the next patrol car run can be solved, and from the stored contents of the central server 6, the lighting state of the lamp in the predetermined range, and the lighting state of the lamps in the plurality of the predetermined ranges, It becomes possible to monitor arbitrarily. In addition, since the lighting state of each illumination lamp is detected by the lamp imaging device, the illumination lamp lighting state management in the management department, the maintenance service of the illumination lamp in the maintenance department, and the illumination lamp manufacturer The reliability of the number of unlit lamps is improved.

  Moreover, the lighting imaging devices 3A11, 3A12, 3A13, ... 3An1, 3An2, 3An3, 3B11, 3B12, ... 3Bn1, 3Bn2 detect the lighting state information directly from the lamp imaging device to the central server 6. It is not transmitted, but is transmitted to the local servers 41,..., 4n installed near the road edge of the lamp imaging device, so that the communication distance of the lamp imaging device is -It can be short including transmission to calserver 41, ... 4n, and it can be set as the lamp imaging device of the transmission function of a low power. In other words, the power required for relay transmission / reception of each lamp imaging device can be kept small, and it is actually possible to use a small solar cell or a dry cell as a power source.

  Incidentally, since the interval between illumination lights on a Japanese highway is usually 40 m, when the first embodiment of the present invention is applied to a Japanese highway, the communication distance of each lamp imaging device does not reach 80 m, for example 50 m. If the local server is installed within 50 m from the lamp imaging device to which the local server receives transmission, each lighting state information in the wireless communication to the local server is set. If the communication distance of each lamp imaging device is set to, for example, about 50 m, which does not reach 80 m, the number of lighting state information received by each lamp imaging device is reduced and the communication load is reduced. The electric power required for relay transmission / reception of the apparatus can be kept small, and it is actually possible to use a small solar cell or a dry cell as a power source.

  Further, according to the first embodiment of the present invention, as a server that obtains and stores the lighting state detection result of the lamp imaging device, the lighting state detection results of a plurality of lamp imaging devices in a predetermined range are obtained and the predetermined range. The plurality of local servers 41,..., 4n that store the respective lamp lighting state detection results of the plurality of lamp imaging devices are used. For example, a large-scale traffic road or a plurality of park lights are monitored. When there are multiple lamp management and maintenance departments in such cases, the management and maintenance of each local server can be the same as the lamp management and maintenance departments. And simplification of maintenance work.

  Further, according to the first embodiment of the present invention, information necessary for each of the users in the related departments such as the management department, the maintenance department, the manufacturer, etc., can be obtained in real time and in any time. When exchanging lamps, etc., necessary information can be quickly and easily shared between related departments or between related departments, so that lamps can be exchanged efficiently and quickly. The lighting time can be shortened. In addition, since future ordering information (information such as the number of unlit lamps, lifespan, etc.) can be obtained in advance for the manufacturer, it is not necessary to carry in excess of inventory such as lamps, and appropriate inventory management can be performed. Production planning and delivery planning can be flexibly performed. In a related department, a general-purpose personal computer or a mobile phone can be used as the monitoring device 6 to obtain necessary information from an arbitrary place at an arbitrary time.

  In FIG. 1 described above, a lamp imaging device that transmits lighting state information to the local servers 41,... 4n is specified, and the specified lamp imaging device is in the lighting state of another lamp imaging device. Information may be received, relayed, and transmitted to a corresponding local server. For example, the lamp imaging device 3B12 is specified as a lamp imaging device that transmits lighting state information to the local server 41, and the specified lamp imaging device 3B12 is connected to the other lamp imaging devices 3A11, 3A12, 3A13, and 3B11.
