る。2. Description of the Related Art Heretofore, this type is as follows. The bulbs of the tunnel illumination lights are broken one by one due to their respective lifetimes. If the number of spots increases, the lighting effect in the tunnel will worsen. Therefore, ball replacement work at the spots is planned and implemented, and traffic safety measures are taken to improve illuminance. In the current tunnel, the ball breaking measurement is an inefficient and inefficient measurement that only relies on visual inspection by walking at low speed of a road patrol vehicle equipped with a tail guard in a tunnel without a walkway or a provisional two-lane structure. Measurements have sometimes been made with risky methods. In particular, recently, even on a provisional line with one lane on each side, the number of times to stop and avoid inspection work has drastically increased with the increase in traffic volume, and every time it is necessary to make a U-turn between ICs and restart the work, The development of safe and efficient inspection methods was necessary. On the other hand, in tunnel lighting measurement, the measurement staff carried the measuring equipment and measured the illuminance at regular intervals, so it was necessary to regulate the speed in the tunnel, and it was necessary to work at night, At present, only about twice a year can be measured. In addition, the same kind of survey method is used for design illuminance confirmation surveys of IC peripheral facilities after road construction and periodic illuminance measurement in SA, PA, etc., but before and after cleaning or replacement of lighting lights. It is difficult to measure uniform illuminance because it is difficult to measure the same location in the above.

That is, 1. An illumination detection photosensor 3 capable of quickly measuring a light / dark signal of tunnel illumination during normal high-speed running is used. 2.

距離補正する測定システムを開発した。In order to accurately determine the position of the illuminating light 1 at which the ball is cut, it is necessary to accurately measure the light position (distance) of light under high-speed measurement conditions. To measure the distance information in the tunnel, a (red) light is projected from a measuring vehicle onto a polarized reflector (special reflector) 6 attached to the interior panel of the tunnel at regular intervals (or according to a lighting arrangement pattern), and reflected. We have developed a measurement system that corrects the approximate distance calculated by converting the axle rotation speed of the measurement vehicle into a pulse signal by accurately detecting the position using a detection system using a photoelectric switch.

できる。FIG. 11 shows an embodiment of the present invention, in which a light-dark signal of the illumination light 1 in a tunnel using a pen oscilloscope having high frequency response is measured (measuring speed 70 km / h,
(Chart speed 10 cm / s). Since the amplitude of brightness and the flickering waveform pattern of light according to the frequency of the AC power supply greatly differ depending on the wattage of the illumination light 1 and the length of the illumination light 1, the out-of-ball state and the out-of-sphere prediction for each lamp type ( It can be seen that the waveform of the low frequency appears remarkably). FIG. 11 also shows a measurement example of a position signal detected from a polarized reflector attached to an interior plate located below the first, ninth, and 16th illumination lights 1 from the tunnel entrance. The difference between the distance signal measured by the position detection optical sensor 4 and the illumination position measured by the illumination detection photosensor 3 is 0.0, which corresponds to a distance error of about 1 m in the latter signal.
Although a time delay of about 5 seconds occurs, the cause is a fixed time delay required for arithmetic processing such as a maximum input signal. Therefore, if a fixed time correction is performed, accurate detection of an illumination position can be performed. It is possible. By using the two types of position detecting optical sensors 4 and the axle sensor 5 together, the position of the illumination light 1 can be detected within a measurement error range of about 10 cm.

ーで誰でも簡単に操作できるメリットは大きい。Further, in order to automatically determine the position of the bulb of the illumination light 1 by a personal computer, a dedicated device for converting an analog signal of the illumination light amount into a digital signal and recording it is required. FIG. 12 is a system configuration diagram of a tunnel illumination insufficiency determination recorder, and FIG. 13 is a schematic configuration diagram of a measurement device for automatic determination. The two types of signals from the illumination detection photosensor 3 and the position detection light sensor 4 are amplified and A / D-converted by an amplifier, and then are converted into digital signals at a measurement interval of about 1/1000 sec (70 km / h at 2 cm intervals). Recorded on a dedicated recording logger. These measurement records are based on the intensity of light and darkness and the blinking cycle pattern of the light according to the lamp type (1/100 sec at a frequency of 50 Hz of a commercial AC power supply).
Using the differences in the waveforms of each of the tunnels, a comparison is made with the arrangement pattern of the luminaires of the tunnels recorded in the personal computer in advance, and the positions and types of the bulbs of the illumination lights 1 and the types of the dirt or the lamp life of the lamps. Early prediction can be automatically determined. Furthermore, if the required number of illuminance sensors (generally, about three) are mounted on the measurement vehicle, continuous illuminance measurement in tunnels and facilities around the IC can be performed simultaneously at high speed. With a commercially available pen oscilloscope recorder, not only can it not be automatically distinguished with only a single function,
Despite the disadvantage that the amount of recording paper used for measurement is huge and the carrying and operation methods are complicated, the digital dedicated recording device can be made compact for portable use, so it is maintenance-free and easy for anyone to operate. The benefits are great.

By using the present invention, it is possible to predict the replacement quantity and replacement location (lamp number) for each ball type or the lamp replacement time before maintenance and replacement work only by measuring the illumination light amount during normal high-speed driving. Become. As shown in the embodiment, in the measurement by the multi-view photosensor arranged radially across the traveling direction, it is possible to detect the light / dark signal independent of the traveling position. In addition, the adoption of a double-type light-shielding hood structure that shields unnecessary external light and detects the brightness of only the illumination light can be achieved by analog recording with a recorder capable of high-speed recording of high-frequency electric signals. The type of the illuminating light 1 can be detected using the photosensor 3 for illumination detection even in a section where the installation intervals of the lighting fixtures are narrow, such as a section of increased lighting.

There is a great merit that many existing tunnels can be dealt with simply by investing in equipment with no power and inexpensive measuring equipment. Furthermore, in the basic lighting section in the tunnel, the lamp can be replaced by predicting a point before the ball runs out, so that it is useful for improving the visual environment in the tunnel and the comfortable running performance for road users. Therefore, if the present invention is used, the maintenance measurement work such as the investigation of the out-of-light bulb of the lighting and the illuminance measurement of various lighting facilities can be greatly improved in efficiency and speed as compared with the current visual inspection and check work, It greatly contributes to improving the safety of inspection work. The application of the present invention is not limited to the illumination measurement in the tunnel of the present embodiment.
