The transmission power of the DU communication device 11 is controlled.

By the way, the operation of the processor 34 constituting the monitor control unit 12a of the ODU-SV unit 12 is also monitored as shown in FIG. That is, the watchdog timer 40 outputs a CPU alarm signal to the MUX 31 as an abnormality has occurred in the processor 34 unless a signal of a constant cycle comes from the processor 34 within a predetermined time.
The MUX 31 multiplexes this CPU alarm signal on the serial monitoring data from the URT 33 and sends it to the demultiplexing unit 17c of FIG. 3 via the control communication line 22b.

As shown in FIG. 3, the demultiplexing unit 17c demultiplexes the transmitted multiplexed signal, outputs serial monitoring data to the communication control unit 17b, and outputs a CPU alarm signal to the monitoring control unit 17a. . The operator of the monitor control unit 17a receiving this CPU alarm signal
An off-line control signal is output when the cause of the abnormality is investigated, and a CPU reset control signal is output from the monitoring control unit 17a to the demultiplexing unit 17c when the processor 34 needs to be started up immediately. In the demultiplexing unit 17c, the offline control signal or the CPU reset control signal is multiplexed with the serial control data from the communication control unit 17b (the offline control signal or the CPU reset control signal is added to each predetermined bit position of the frame structure) for control. The data is output to the DMUX 32 shown in FIG. 4 via the communication line 22a.

As shown in FIG. 4, in the DMUX 32, the transmitted multiplexed signal is separated and the serial control data is UR.
In addition to outputting to T33, an offline control signal or a CPU reset control signal is sent to the serial / parallel converter 3
5 to the protection unit 36. The protection unit 36, for example, sends an off-line control signal to a predetermined bit position of the frame structure n
When the number is detected, an output signal is output to the NMI register 37, and the NMI register 37 outputs an interrupt signal NMI that cannot be masked to the processor 34. As a result, the processor 34 has been executing O online until then.
The execution of the supervisory control software of the DU communication device 11 is stopped, the software of the offline control is started, the transfer command signal from the URT 33 is awaited, and the data in the logging memory 39 is transferred via the URT 33 and the MUX 31 to the IDU-SV of FIG.
It is sent to the monitor control unit 17a of the unit 17. In the monitoring controller 17a, the data in the logging memory 39, that is, the processor 34
Based on the time-series data of the operating condition of the processor 34 immediately before the occurrence of the abnormality, the operator analyzes the cause of the abnormality. That is, it is possible to infer what kind of phenomenon has occurred in the processor 34 from those data.
The cause that the software has a bug is investigated.

Further, for example, when the protection unit 36 detects the CPU reset control signal at the predetermined bit position of the frame structure n times, it outputs an output signal to the reset unit 38, and the reset unit 38 outputs the reset signal to the processor 34. To do.
As a result, the processor 34 is reset to the initial state when the power is turned on, and the temporary recovery is possible.

As described above, the supervisory controller 17a of the IDU-SV unit 17 is replaced by the supervisory controller 12 of the ODU-SV unit 12.
By receiving the CPU alarm signal from the watchdog timer 40 of a, the supervisory controller 17a can easily identify that the control communication line 22b has no disconnection and an abnormality has occurred in the processor 34. Also, the processor 3
4 through the control communication line 22b
If the monitoring data indicating the operating state of the OUD communication device 11 is not sent to the monitor controller 17a and the monitor control unit 17a does not receive the CPU alarm signal from the watchdog timer 40, the control communication line 22b is disconnected. Can be easily identified. When it is possible to identify that an abnormality has occurred in the processor 34, the monitoring controller 17a

Only the V and ODU-SV parts are shown. The configurations of the IDU communication device and the ODU communication device in the second embodiment are the same as those of the IDU communication device 16 and the ODU communication device 1 shown in FIG.
The configuration is the same as that of 1.

In the figure, the ODU-SV section 52 comprises a monitor control section 52a, a communication control section 52b, a test pattern signal detector 52c, and a changeover switch 52d. The monitoring control unit 52a controls the monitoring control unit 51a of the IDU-SV unit 51, which will be described later, for monitoring the voltage of each unit of the ODU communication device, monitoring the generation of alarms, monitoring the reception power, controlling the transmission power, and the like. Do it below. The communication control unit 52b is
The monitor control unit 52a interfaces with the monitor control unit 51a of the IDU-SV unit 51 for transmitting and receiving a serial signal. Monitoring data and control data are carried on this serial signal. The detector 52c is connected to the control communication line 53a and detects a test pattern signal sent from a generator 51c of the IDU-SV unit 51 described later. When the detector 52c detects the test pattern signal, it outputs a changeover signal to a changeover switch 52d. . The changeover switch 52d is provided in the middle of the control communication lines 53a and 53b connecting the communication control unit 52b and the communication control unit 51b of the IDU-SV unit 51, which will be described later, and is normally a switch shown by a solid line in the figure. Is connected to the communication control unit 52b and the IDU-S.
The communication control section 51b of the V section 51 is connected, but when a switching signal is output from the detector 52c, it is connected to the switch position shown by the broken line in the figure, and the control communication line 53 is connected.
a is connected to the control communication line 53b.

Further, the IDU-SV section 51 includes a monitor control section 51a, a communication control section 51b, a test pattern signal generator 51c, and a test pattern signal detector 51d.
And a changeover switch 51e. The monitoring control unit 51a monitors and controls the IDU communication device, and further monitors and controls the ODU communication device via the monitoring control unit 52a of the ODU-SV unit 52. In the communication control unit 51b, the monitoring control unit 51a is the ODU-SV unit 5
The communication with the second monitoring control unit 52a is controlled. The generator 51c is a test pattern signal generator that generates a serial pattern signal that cannot exist in the communication performed between the monitoring control unit 51a and the monitoring control unit 52a. The detector 51d is a detector which is connected to the control communication line 53b and detects a test pattern signal transmitted through this line. The changeover switch 51e is used for the control communication line 5
Although it is provided in the middle of 3a and is normally connected to the switch position shown by the solid line in the figure, it is connected to the switch position shown by the broken line in the figure by the switching signal from the monitoring control section 51a, and is connected from the generator 51c. And sends the test pattern signal of the above to the control communication line 53a.

The IDU-SV section 5 configured as described above
1 and the operation of the ODU-SV unit 52 will be described. In addition,
The operations of the IDU communication device and the ODU communication device of the second embodiment are the same as the operations of the IDU communication device 16 and the ODU communication device 11 of FIG. 3, and therefore the description thereof will be omitted.

First, the supervisory control unit 5 of the IDU-SV unit 51.
1a, the monitor control unit 52a of the ODU-SV unit 52
While receiving the serial monitoring data from the control communication line 53b via the control communication line 53b, the monitoring control unit 51a does not output the switching signal to the changeover switch 51e, and therefore the changeover switch 51e is indicated by a solid line in FIG. When connected to the switch position shown, the test pattern signal from the generator 51c is not output to the control communication line 53a. Therefore, the detector 52c of the ODU-SV unit 52 does not detect the test pattern signal and does not output the switching signal to the switching switch 52d. Therefore, the changeover switch 52d is connected to the switch position shown by the solid line in FIG. 5, whereby the communication control unit 51b and the communication control unit 52 are connected.
It is connected to b via control communication lines 53a and 53b, and normal serial monitoring data and serial control data are transmitted and received.

On the other hand, the supervisory control unit 5 of the IDU-SV unit 51
1a, the monitor control unit 52a of the ODU-SV unit 52
When it becomes impossible to receive the serial monitoring data from, the monitoring controller 51a outputs a changeover signal to the changeover switch 51e, and connects the changeover switch 51e to the switch position shown by the broken line in the figure. Therefore, the test pattern signal is output from the generator 51c to the control communication line 53a, the detector 52c detects the test pattern signal, and outputs the switching signal to the changeover switch 52d. Therefore, the changeover switch 52d is connected to the switch position shown by the broken line in the figure, whereby the test pattern signal from the generator 51c is returned and the control communication line 5 is returned.
It is sent to the detector 51d via 3b, and the detector 51d detects the test pattern signal.

That is, the fact that the detector 51d has detected the test pattern signal means that the control communication line 53a,
53b shows that there is no disconnection, and the reason why the supervisory control unit 51a of the IDU-SV unit 51 cannot receive the serial supervisory data from the supervisory control unit 52a of the ODU-SV unit 52 is the ODU-SV unit. It can be specified to be within 52. If the detector 51d does not detect the test pattern signal, there is a break in the control communication line 53b.
The monitoring control unit 51a of the DU-SV unit 51 changes the ODU-SV
It can be easily determined that the serial monitoring data from the monitoring control unit 52a of the unit 52 cannot be received.

Therefore, when the remote control device side receives this alarm signal, it can be easily specified that there is no disconnection in the control communication line and that an abnormality has occurred in the monitoring control means. On the other hand, when the data indicating the operating state of the wireless device is not sent from the supervisory control means to the remote control device side through the control communication line and the alarm signal is not received, the control communication line is broken. Can be easily specified.

Further, when the remote control device side receives the alarm signal, it instructs the monitoring control means, for example, to send logging information or reset to the initial state. As a result, appropriate recovery measures will be taken immediately.

When data indicating the operating state of the wireless device is not sent from the supervisory control device side to the remote control device side via the control communication line, the remote control device side monitors via the control communication line. A test pattern signal is sent to the control device side, and is sent back to the monitoring control device side. As a result, if the test pattern signal is returned and returned,
There is no disconnection in the control communication line and it can be specified that there is an abnormality on the monitoring control device side. On the other hand, if the test pattern signal is not returned, it can be easily specified that the control communication line is disconnected.
