The power supply circuit 50 is a circuit that converts the voltage of the power supply provided in the transportation means (automobile) 40 and supplies it to the above-mentioned units.

The operation of the system thus configured will be described.

First, in the circuit shown in FIG. 2, it is assumed that the dip switch 38 is used to set the numbers for identifying the columns to which the respective lamp fault detection circuits 10 are attached.

The input port 23 is supplied with the voltage value V _A detected by the first voltage detection circuit 60 and the voltage value V _B detected by the second voltage detection circuit 61. On the other hand, the current value I detected by the current detection circuit 20 is given to the ADC 21, and AD
C21 converts this into a digital value. In each of the above values V _A , V _B , and I, V _A represents the ON / OFF state of the photoswitch 7, V _B represents the output voltage of the ballast 8, and I represents the current value supplied to the lamp. There is. CPU
32 performs the processing shown in FIG. 4 based on these values provided from the input port 23 and ADC 21, respectively.

First, the CPU 32 determines whether the photo switch 7 is on or off based on V _A (step 101). CPU32
Determines that the photo switch 7 is on, determines that V _B is a normal value (step 102), and then determines that I is a normal value (step 103), this luminaire is normal. A signal DT to the effect is output from the output port 28 together with the column identification number AD to which this lighting fixture is attached (step 104). These signals are the modulator 29, the drive circuit
The light is emitted to the outside by the light emitting diode 26 via 27.
The format of the signal at this time is shown in FIG. Here, there are three types of data DT: normal "00", lamp failure "01", and ballast abnormality "10". In this case, "00" is sent because it is normal.

If the CPU 32 determines in step 101 that the photo switch 7 is off, the CPU 32 immediately executes step 104.
Proceed to and send a normal signal "00".

If the CPU 32 determines in step 102 that V _B is not a normal value, the CPU 32 proceeds to step 105 and stabilizes the ballast 8.
Is transmitted to the outside in the same manner as in step 104, and the signal "10" indicating that is abnormal is sent to step 10
Return to 2.

If the CPU 32 determines in step 103 that I is not a normal value, the CPU 32 proceeds to step 106 and sends the signal "01" indicating a lamp failure and the pole identification number AD to the outside in the same manner as in step 104, Return to 102.

The received data conversion circuit 45 converts the data into processing data for the microcomputer 46. CP of Microcomputer 46
U performs the processing shown in FIG. That is, this CPU determines whether the data supplied from the reception data conversion circuit 45 is "00" (step 201), "01" (step 202), or "1".
It is judged whether it is 0 "(step 203). The data is" 0 ".
If it is "0", it is normal and the process is terminated.
If the data is "01", the pillar identification number and status (non-lighting) are stored in the storage device 47 (step 204). If the data is "10", the pillar recognition number and status are stored in the storage device 47. The (ballast abnormality) is stored (step 205). If the data is none of the above, the column identification number and status (communication abnormality in this case) are stored in the storage device 47 (step 206). When storing each situation, the date and time at that time are also stored.

When the moving means 40 passes all the vicinity of the 1 to n columns 1, the storage device 47 stores the data as shown in FIG.

According to the present invention, an abnormality of a lighting device such as a lamp not lit or an abnormality of a ballast can be easily detected even in the daytime when the lamp is not lit. In addition, since it is not necessary to go to the pillars and the inspection work can be performed while riding in the vehicle, the time required for the work can be significantly shortened and the maintenance cost can be reduced.

Further, according to the present invention, it is possible to display the situation of a desired place among the situations of a plurality of places of the lighting fixture, so that the maintenance management becomes extremely easy.

Further, according to the present invention, since only the data of the luminaire in which the abnormality is detected is displayed, this also makes maintenance very easy.
