(“ID3” + “ID4”). Similarly, data 3 stored in master station device 22
(“ID1” + “ID2” + “ID3”) can be used when the adjacent slave station device 5d breaks down, as described later.

Next, the master station device 22 sends data 4 (“ID1” + “ID1” + “ID3” + “I”) from the slave station device 5d.

3)) can be used when the adjacent slave station device 5d fails, as described later.

In the management office, the data 4 (“ID1” + “ID1” + “ID3”) sent from the master station device 22
+ “ID4”) is displayed on the monitor display device 43.
Therefore, the administrator can clearly find out which of the lighting device 1 and the slave station device 5 has failed from this display screen (step 76).

Next, a case of a failure operation, that is, a case where one of the slave station devices 5 fails and data from the slave station device is lost will be described with reference to FIGS. For example, a case where the slave station device 5b breaks down as shown in FIG. 11 will be described.

As shown in FIGS. 11 and 13, when the data transmission time X comes (step 70), each slave station device 5 starts a data transmission process. First, as above,

+ “ID2”) is not created (step 92). On the other hand, data 1 (“ID1”) is stored in the slave station device 5c (step 101), and data 2 from the slave station device 5b is stored.
(“ID1” + “ID2”).

However, since the slave station device 5b is out of order, even if the set data reception timer T3 times out, the slave station device 5c stores the data 2 from the slave station device 5b.
(“ID1” + “ID2”) does not arrive (step 9)

Data 3 (“ID1” +
“ID2 missing” + “ID3”) is transmitted to the slave station device 5d and the master station device 22 (step 94). In the slave station device 5d, the data 3 (“ID1” +
The own station data “ID4” is added to “ID2 missing” + “ID3” and data 4 (“ID1” + “ID2 missing” + “ID”)
3 "+" ID4 ") and transmit it to master station device 22 (step 95).

The master station device 22 stores the data 3 (“ID1” + “ID2 missing” + “ID3”) from the slave station device 5c (step 102) and the data 4 from the slave station device 5d (step 102). "ID1" + "ID2 missing" + "ID3"
+ “ID4”). The master station device 22 receives data 4 (“ID1” + “ID2”) from the slave station device 5d.
(“Delete” + “ID3” + “ID4”), all of the child station devices 5a to 5a constituting the system of the master station device 22 are received.

“ID3” + “ID4”) is stored (step 96) and transmitted to the management office via the existing communication line 42 (step 97).

In the management office, the data 4 (“ID1” + “ID2 missing” + “ID
3 ”+“ ID4 ”) is displayed on the monitor display device 43. In this case, the location where each lighting device 1 and the slave station device 5 are installed and the status of each device at that location, such as whether it is normal or faulty, are displayed at a glance.

That is, the display on the monitor display device 43 is configured to be color-coded to indicate whether the illuminating device 1 is faulty, the slave station device 5 is faulty, or is operating normally. . For example, in the case of this embodiment, "red" is displayed when the illumination device 1 is out of order, and "orange" is displayed because the data is missing when the out-of-office device 5 is out of order.
“Green” when both the lighting device 1 and the slave station device 5 are normal.
The display is color-coded so as to be displayed.

Therefore, the failure of the slave station device 5b is indicated by "orange".
If “ID1” is data indicating that the lighting device 1a is out of order, “red” is displayed. Therefore, the administrator determines the lighting device 1a from the display color of the display surface of the monitor display device 43. It is possible to identify at a glance whether the device has failed or whether the slave station device 5b has failed.

Next, a case where the terminal station 5a at the terminal has failed will be described with reference to FIG. At the time of data transmission time X (step 70), all slave stations 5a
5d and the data reception timer T5 of the master station device 22 are started. At this time, since the terminal device 5a at the terminal is out of order, the terminal device 5b
Since the data from the slave station device 5a cannot be received, when the reception timer of the slave station device 5b times out, the slave station device 5b transmits ("ID1 missing") as data 2 of the own station.
+ "ID2") (step 110), and is transmitted from the slave station device 5b to the next-stage slave station device 5c and further to the next-stage slave station device 5d (step 111).

When the slave station device 5c receives the data 2 (“ID1 missing + ID2”) from the preceding slave station device 5b, the data 2 (“ID1 missing” + “ID2”) is transferred to the own station data (“ID1 missing + ID2”). Data 3 (“ID1 missing”) +
“ID2” + “ID3”) is created and transmitted to the master station device 22 adjacent to the next-stage slave station device 5d in the same manner as described above (step 112).

In the slave station device 5d, the data 2 (“ID1 missing” + “ID2”) received from the slave station device 5b immediately before the received stage.
Is stored (step 121), and data 3 (“ID1 missing” + “ID2”) from the preceding child station device 5c is stored.
+ “ID3”). Note that the data 2 (“ID1 missing” + “I
D2 ”) can be used when the slave station device 5c at the preceding stage breaks down, as described later.

Next, the slave station device 5d transmits the data 3 (“ID1 missing” + “ID2” + “I”) from the preceding slave station device 5c.
D3 ”), the data 3 (“ ID1 missing ”+
“ID2” + “ID3”) contains the own station data (“ID
4 ") (" ID1 missing "+" ID2 ")
+ “ID3” + “ID4”), and transmitted to the adjacent master station device 22 (step 113).

The master station device 22 stores the data 3 ("ID1 missing" + "ID2" + "ID3") from the slave station device 5c (step 122) and the data 4 (from the slave station device 5d) (step 122). "ID1 missing" + "ID2" + "ID3"
+ “ID4”). The master station device 22 receives data 4 (“ID1 missing” + “ID”) from the slave station device 5d.
2 "+" ID3 "+" ID4 "), all the slave station devices 5a to 5a constituting the system of the master station device 22 are received.
The collection of data from d ends. Therefore, the master station device 2
2, the data 4 (“ID1 missing” + “ID2” +
“ID3” + “ID4”) is stored (step 122), and transmitted to the management office via the existing communication line 42 (step 114).

In the management office, data 4 (“ID1 missing” + “ID2” + “ID
3 ”+“ ID4 ”) is displayed on the monitor display device 43. In this case, the location where each lighting device 1 and the slave station device 5 are installed and the status of each device at that location, such as whether it is normal or faulty, are displayed at a glance.

Next, a case where two slave stations 5b and 5c fail consecutively and data from the two slave stations 5b and 5c is lost will be described with reference to FIG. explain.

As shown in FIG. 15, similarly to the above, at the data transmission time X (step 70), each slave station device 5 starts a data transmission process. First, similarly to the above, the slave station devices 5a to 5d start the data reception timers T1 to T4, respectively, and the master station device 22 similarly starts the data reception timer T5.

Data 1 transmitted from slave station device 5a
(“ID1”) is transmitted to the slave station devices 5b and 5c (step 130). However, since both the slave station devices 5b and 5c have failed, the data reception timer T2 set for the slave station device 5b, the data reception timer T3 for the slave station device 5c, and the data reception timer T3 for the slave station device 5d
4 times up one after another.

Therefore, in the slave station device 5d, the slave station device 5d
b, since data from the slave station device 5c cannot be received, when the data reception timer T4 times out, the data of the slave station devices 5a to 5c is lost and data 4 (“ID1 missing” + “ ID2 missing ”+“ ID3 missing ”
+ "ID4") (step 131). In this case, the data of the slave station device 5a is also lost, and the data 4 is transmitted from the slave station device 5d to the adjacent master station device 22 (step 132).

Data 4 (“ID
When “1 missing” + “ID2 missing” + “ID3 missing” + “ID4”) is received by the master station device 22, the master station device 22 receives this data 4 (“ID1 missing” + “ID2 missing” + “ ID3 missing "
+ "ID4") and transmit it to the management office via the existing communication line 42 (step 133).

At the management office, the data 4 (“ID1 missing” + “ID2 missing” + “ID
“3 missing” + “ID4”) is displayed on the monitor display device 43. In this case, the normal slave station device 5a is also displayed as missing data. In this case, it is rare that the slave station device breaks down two consecutive times. In such a case, however, the transmission power of the slave station device is increased and the data of the source slave station device is not transmitted. What is necessary is just to reach to three slave station devices.

Here, if the lighting device 1 is normal, but the slave station device installed in the lighting device 1 is out of order, data cannot be transmitted, and data is lost. However, in this case, since the slave station device stores the operation history as data, when the device is actually repaired on site,
The details of the failure can be confirmed.

That is, the display on the monitor display device 43 is configured to be displayed in different colors depending on whether the illuminating device 1 is faulty, the slave station device 5 is faulty, or is operating normally. . For example, in the case of this embodiment, "red" is displayed when the illumination device 1 is out of order, and "orange" is displayed because the data is missing when the out-of-office device 5 is out of order.
“Green” when both the lighting device 1 and the slave station device 5 are normal.
The display is color-coded so as to be displayed.

The present invention is not limited to the relay-type relay transmission as shown in the above embodiment. For example, the transmission / reception power of each slave station device is increased and the data from the slave station device is transmitted. May be set to be directly transmitted to the master station device in the system to which the slave station device belongs. In this case, each data from the slave station device is transmitted to the master station device to which the slave station device belongs. Are transmitted to the management office for each system, and are displayed on the monitor display device 43. Therefore,
From the display screen of the monitor display device 43, it is possible to find the slave station device that has transmitted the failure data.
