Abstract

The invention provides a management system for an illumination facility, which comprises an illuminance measuring instrument, a position detector for detecting a position of the traveling vehicle, and an arithmetic device, which are mounted on a traveling vehicle, wherein the arithmetic device is configured to save a map information, positional data of an illumination lamp, initial data including illuminance data, and the illuminance data as acquired by the illuminance measuring instrument while driving the traveling vehicle, and wherein the arithmetic device is configured to calculate daily management data of the illumination facility based on the positional data of the traveling vehicle as detected by the position detector, the map information, and the illuminance data, and further wherein the arithmetic device is configured to calculate a change of the illumination facility including the illumination lamp based on the initial data and the daily management data.

Claims

1. A management system for an illumination facility comprising:

an illuminance measuring instrument for measuring an illuminance of said illumination facility provided on a general road, an express way or in a tunnel, wherein the illuminance measuring instrument comprises an illuminance measuring unit, a position detector for detecting a position of said traveling vehicle, and an arithmetic device, which are mounted on a traveling vehicle,

wherein said arithmetic device is configured to save a map information, positional data of an illumination lamp which is included in said illumination facility, initial data including illuminance data of said illumination facility, and said illuminance data as acquired by said illuminance measuring instrument while driving said traveling vehicle,

and wherein said arithmetic device is configured to calculate daily management data of said illumination facility based on said positional data of said traveling vehicle as detected by said position detector, said map information, and said illuminance data, and

further wherein said arithmetic device is configured to calculate a change of said illumination facility including said illumination lamp based on said initial data and said daily management data.

2. The management system for the illumination facility according to claim 1, wherein said arithmetic device has a correction coefficient due to a distance from the ground to an illuminance measuring instrument mounting position and a correction coefficient due to a speed of said traveling vehicle, and corrects said illuminance data into corrected illuminance data corresponding to said initial data based on both the correction coefficients.

3. The management system for the illumination facility according to claim 1, wherein said arithmetic device calculates a plurality of different management data based on said initial data and said daily management data and has a selecting function for selecting said plurality of different management data, and wherein said arithmetic device further comprises a display unit and an operation unit and said management data corresponding to a selected function is displayed on said display unit by selecting one of said functions by said operation unit.

4. The management system for the illumination facility according to claim 3, wherein said management data as displayed is a display as superimposed a measurement area on said map information.

5. The management system for the illumination facility according to claim 3, wherein, as to said management data as displayed, said measurement area is superimposed on said map information, a cursor indicating a measuring position is displayed, and the illuminance information of a position of said cursor is displayed.

6. The management system for the illumination facility according to claim 3, wherein said management data as displayed is an enlarged display of a measurement area.

7. The management system for the illumination facility according to claim 3, wherein said management data as displayed is a three-dimensional display of measurement data.

8. The management system for the illumination facility according to claim 3, wherein said management data as displayed is the three-dimensional display showing a difference between said initial data and said daily management data.

9. The management system for the illumination facility according to claim 3, wherein said management data as displayed is the display of a change over time of an illuminance of a specified illumination lamp.

10. The management system for the illumination facility according to claim 1, wherein standard data of said illumination lamp is further stored in said arithmetic device, said arithmetic device calculates the change over time of said illumination lamp based on said daily management data and diagnoses a soundness of said illumination lamp based on the change over time of said illumination lamp and said standard data.
