BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. Lighting equipment for roads and the like uses discharge lamps such as sodium lamps and mercury lamps, and has a configuration in which the lamps are arranged at regular intervals. The unit of a discharge lamp such as a sodium lamp has a configuration as shown in FIG. In the figure, reference numeral 6 denotes a power supply, which is usually a 100 V or 200 V circuit. 7 is a reactor, 8 is a power factor improving capacitor, 9 is a sodium discharge lamp, and the power factor improving capacitor may not be used in some cases.

FIG. 2 shows a vector diagram of voltage, current and impedance when a current is supplied to a circuit in which no capacitor is connected in the circuit of FIG. In FIG, I _S is the current immediately after starting, I _L is the current in the stable state after the predetermined time elapses. When the power is turned on and started, the current value becomes I
Large as the _S, stabilized at the value of I _L while drawing a semicircular trajectory with the passage of time. For example, FIG. 3 shows an example of a starting current of a low starting current type sodium discharge lamp. FIG. 4 shows a current vector diagram after stabilization when a capacitor is connected. In this case, the delay angle φ of the current vector with respect to the voltage vector is smaller than when the capacitor is not connected.

FIG. 5 shows the relationship between the voltage and the current when a voltage is applied to the luminaire, for example, in the case of a low starting current type sodium discharge lamp. This characteristic has a characteristic peculiar to each kind of the illumination lamp.

Embodiment 1 Monitors a plurality of illuminating lamps of the same rating such as the sodium discharge lamp shown in FIG. FIG. 6 shows the configuration. In the figure, reference numeral 50 denotes a power supply of 100 V or 200 V, reference numeral 51 denotes a power supply line to be supplied to each block, and reference numeral 10 denotes a first block in which a lighting device of 10 to 20 lamps is used as one block. 11 is power line 5
1 is a power supply line, 12 is current detection means for detecting the current of the first block, 13 is voltage detection means for detecting the voltage value of the power supply line, 14 is the current value of the power supply circuit based on a command from the master station, A signal conversion unit for detecting a voltage value and converting the detected current value to a voltage signal and a current signal, and a transmission processor for taking in a detection signal from the master station and transmitting the converted voltage signal and the current signal are provided. 20 is the second block,
Reference numeral 30 denotes a third block, which is configured similarly to the first block 10. Each part of the second block 20 displays 1 as the tens digit of the symbol of the first block as 2, and each part of the third block 30 displays the tens symbol as 3.

Reference numeral 54 denotes a monitoring master station, which stores a reference current value at a reference voltage value for each block, and issues a voltage and current detection command to the monitoring terminals 14, 24, and 34 of each block. , The voltage signals and current signals detected by the monitoring terminals 14, 24, and 34 are fetched, and for each block, the current value of the current signal is corrected to the current value at the reference voltage according to the voltage value of the voltage signal, and A calculation unit that determines a difference by comparing with a reference current value stored in advance for each time, and determines that an abnormality occurs when the determined difference exceeds a preset value; and a transmission processor that outputs a determination result. . A transmission line 52 communicates between the monitoring terminal and the monitoring master station. Reference numeral 60 denotes a central monitoring panel, which is in communication with the monitoring master station via a transmission line 53.

The configuration in which a plurality of lighting devices are connected in this way is a configuration in which a plurality of the configurations shown in FIG. 1 are connected in parallel, and a power factor improving capacitor is individually connected to each lighting device. The following description is based on the assumption that FIG. 2 shows the current flowing through one block in the stabilized state. If I _S is the number of connected luminaires N, the current is N times the current of one lamp, and the current and voltage vectors of each block are as shown in FIG. In the figure, e is a voltage, I ₁ , I ₂ ,
I ₃ , ΔI _N−1 , and I _N are currents flowing through each lighting fixture, and φ is a phase angle of the current with respect to the voltage e.

As shown in FIG. 5, in the case of a sodium discharge lamp, for example, the current value changes due to the fluctuation of the power supply voltage. Since the determination cannot be made accurately, the current value at the time of the reference voltage is corrected, and the corrected current value is compared with the reference current value. , It can be detected that the current is not supplied due to a broken ball or the like.

In accordance with the above situation, the monitoring master station 54
In the configuration, the current value at the time of the reference voltage in the normal state is stored as the reference current value, and the circuit current is detected at regular time intervals (or periods) and converted into the current value at the reference voltage, and this converted The current value is compared with the stored reference current value. If the difference is equal to or greater than 1 / parallel number, the difference is determined to be abnormal, and if the difference is equal to or less than the control value, it is determined to be normal. By configuring to output the determination result, it is possible to accurately detect an abnormality such as a broken ball for each block. The detected abnormality information is displayed on the central monitoring panel 60 via the transmission line 53.

However, as the usage time of the lighting equipment is accumulated, the deterioration gradually progresses, and the current value in a normal state changes. If it is determined to continue using the initial current value as the reference current value, If the characteristics change due to aging progresses, there is a possibility that the judgment will be erroneous. In order to avoid such a situation, the reference current value initially stored as the reference current value when the current value detected for monitoring for a fixed time or at regular intervals is determined to be normal. Even if there is a change in the lighting characteristics over time, abnormalities such as a broken ball in the lighting equipment are accurately detected and displayed on the central monitoring panel, and the abnormal lighting lamp is displayed. But can be exchanged accurately and efficiently.

Embodiment 2 FIG. Lighting equipment such as sodium is a discharge lamp, which is connected to a reactor in series and has a poor power factor. Therefore, a power factor improving capacitor is usually connected. When one of the luminaires in this case breaks the ball, as shown in FIG. 8, the effective current for one decreases, and the capacitor is charged, so that one phase _leading current I _XN remains, The phase angle becomes a vector moved in the leading direction. By adding a part for detecting the phase angle to the configuration of FIG. 6, it is possible to more accurately determine whether the current is normal or abnormal by comparing the current fluctuation and the phase fluctuation with the normal value. An abnormality such as a broken ball can be detected.

When the number of luminaires in one block is reduced, an abnormality such as a broken ball can be sufficiently determined only by a change in phase. In this case, a current detecting means and a voltage detecting means having a simple configuration can be used.

Embodiment 3 In the second embodiment, the phase of each block is detected to determine whether the block is normal or abnormal. However, a power factor meter is installed in the electric circuit of each block, and the monitoring master station monitors the power factor change of each block. It is good also as a structure which judges normal or abnormal. When the number of lighting fixtures arranged in parallel is small, an abnormality such as a broken ball is accurately detected and displayed on a central monitoring panel.

In this configuration, only the power factor detecting means is provided.
It is not necessary as a monitoring terminal, only the monitoring master station is required,
It becomes an inexpensive and simple luminaire monitoring device.

Embodiment 4 Lighting fixtures are used for a long time, and when they reach the end of their service life, flickering occurs. It is important to quickly detect this flicker phenomenon. In the fourth embodiment, the flicker phenomenon is easily detected.

[0028] The flicker phenomenon of the discharge lamp is a phenomenon in which the voltage drop at the electrode portion becomes large and the discharge cannot be sustained by the applied voltage. It is a phenomenon that greatly changes. By repeating current measurement at relatively short intervals, flicker can be detected from a difference between current measurement values.

In the method of detecting flicker, the configuration of the lighting equipment monitoring device is the same as the configuration shown in FIG. 6, and the function of the monitoring master station is measured for the monitoring terminal of each block by one measurement of voltage and current. A detection command is given a plurality of times at fixed intervals for each unit, the current value at the time of the reference voltage is detected for each block and stored in the storage unit, and the maximum value and the minimum value of the current value detected a plurality of times are detected. Is added, and a function of judging a flicker abnormality when the difference exceeds a preset range is added.

[0030] With this configuration, the same monitoring device detects an out-of-ball abnormality and a flicker abnormality of the lighting equipment and displays them on the central monitoring panel.

Embodiment 5 Embodiment 4 FIG. In the first embodiment, the flicker phenomenon was detected by the change in the current. However, the flicker phenomenon not only changes the current but also greatly changes the phase. In the same manner as the configuration shown in the above, a configuration for detecting the phase from the detected voltage data and current data is added to the monitoring master station, and a plurality of detection commands are given at fixed intervals for each measurement unit, and The current value and the phase at the time of voltage are detected, the data for each block is stored in the storage unit, and the difference between the maximum value and the minimum value of the current value detected a plurality of times and the phase difference are obtained. By adding a function of judging a flicker abnormality when exceeding a preset range, it is possible to accurately detect both phenomena of flicker and flicker.

Embodiment 6.1 When the number of parallelly connected lighting fixtures in one block is reduced, the fluctuation rate of current and phase is increased, and it becomes easy to detect an abnormal phenomenon, and it is possible to detect only phase. is there. Sixth Embodiment Is
In this configuration, both abnormalities such as an out-of-ball abnormality and a flicker abnormality of the lighting equipment are detected only by a phase change.

Embodiment 6 FIG. Is the same as that of the second embodiment.
The overall configuration is the same as that of the first embodiment except that the function of the monitoring master station is determined as normal or abnormal only by detecting the phase and using only the phase. The configuration of the monitoring parent station is such that a command for detecting voltage and current is issued to the monitoring terminal, a function of detecting a phase from the detected voltage and current is provided, and a phase in a normal state is stored. It is configured to detect multiple phases at a fixed interval for each measurement unit, and determine that flicker is abnormal when the difference between the maximum value and the minimum value of the multiple phase data exceeds the preset phase range. Things. When there is no difference between the maximum value and the minimum value of the detected phase difference, the difference between the detected phase difference and the preset phase is obtained. It is.

The only thing that can be detected by a change in phase is that a capacitor is connected to the lighting equipment, and when the number of blocks connected in parallel is small, an abnormality can be accurately determined, and the configuration of the monitoring device is simple. Configuration.
