。Conventionally, a device of this type is shown in FIG. 1. In the figure, 1lli high lot signal generator, input signal distributor at +21, frequency converter and power amplifier at (3), output signal selection switch at (4), fil, te
The pilot signal detector consists of a frequency converter and a pilot 3-wavelength detector. (7) The zero-order operation detected by the second fault detector will be explained. As shown in Fig. 1, the pilot signal of the pilot signal generator (1) is input to the frequency converter and the output of the power amplifier +31, and the pilot signal is monitored by the pilot signal detector +61 and tel. A fault detector (7) detects system fluctuations.
) Since the conventional power monitoring device is configured as described above, if one side of the system goes into a fault state, it is impossible to detect the fault, and when the carrier level is low, This F14rz has the drawbacks that it is extremely difficult to set up due to phenomena such as poor performance and sensitivities of the working system and standby system are not aligned. By using independent detection circuits for input and output in the standby system, the carrier,
Level abnormalities and failures of each unit are divided into working and standby systems, and the deviation from the initial setting is t-1 by comparing all input and output power pipes.
I! The purpose is to provide a device that can emit Ii.
