欠点があつた。 In a communication system consisting of a main system, a standby system, and a separate monitoring device, when the monitoring device detects an abnormality in the main system's operation, the monitoring device sends a signal to the standby system, and Switch the device into operation. The monitoring device checks the recovery status of the main system and switches over again, or keeps the main system on standby as a standby system. Generally, it is desirable for the main system and standby system devices to have the same circuit configuration from the viewpoint of manufacturing and maintenance. Therefore, if a monitoring device has not yet been implemented as a communication system, or even if it has been implemented, when testing each system to transmit transmission signals and various operation control signals, each system will only operate in the same way. There was a drawback that it was not possible to conduct tests separately for each system.

ある。 The purpose of the present invention is to improve the above-mentioned drawbacks, so that when a monitoring device is installed in the main system and standby system, it is normally controlled by the monitoring device, and when it is not installed or during testing, it is controlled by the additional monitoring device. Therefore, it is an object of the present invention to provide a monitoring device for a communication system that can be controlled.

SVに印加される。 Embodiments of the present invention shown in the drawings will be described below. In the block diagram shown in Fig. 1, the main system (hereinafter referred to as #N system in this specification) and the standby system (hereinafter referred to as #E system) connect substrates Pt1 and Pt2 in cascade to data signals. In addition to the main monitoring device SV, additional monitoring devices μSV each mounted on the board Pt1 are provided. The supervisory control signal SVS from the main supervisory device SV is input to the additional supervisory device μSV to control the operation/non-operation of the board Pt1.
In addition, in Figure 1, the main monitoring device is connected to each board Pt1 and Pt2.
It goes without saying that an alarm transmission line is required to notify the SV of abnormal conditions, and it is not described here because it would be complicated. The additional monitoring device μSV has the circuit configuration shown in FIG. 2, and both the #N system and the #E system are the same.
The #N system additional monitoring device μSV receives the #N system board Pt2 in addition to the monitoring control signal SVS from the main monitoring device SV.
Alarm signal ALM2 from #E system board Pt1,
Each alarm signal E-ALM1, E-ALM2 from Pt2
is inputting. Since the information regarding the #N system board Pt1 is obtained by the additional monitoring device μSV itself because the additional monitoring device μSV exists on the board Pt1 and is in operation (that is, not in an alarm state), it is necessary to apply the alarm signal ALM1. is not particularly required. There is a similar signal input for the additional monitoring device μSV in #E system, and the signals of E-ALM1 and E-ALM2 are the signals from #N system, so N-ALM1, N-
Apply as ALM2. Also, in Figure 1, SW
1 is a switch for the supervisory control signal SVS, SW
2 is a switch for the signal from the #E system to the additional monitoring device of the #N system, and SW3 is a switch for the signal from the #N system to the #E system.
This indicates a switch to the system, and each operates in conjunction with each other. Further, black circles indicate terminals at potential "H". The supervisory control signal SVS is converted into a signal *SVPT by the polarity inversion circuit INV.
After that, the signal is applied to the #N system additional monitoring device μSV via switch SW1, and the signal that passes through another polarity inverting circuit INV0 is applied to the #E system additional monitoring device μSV.
Applied to SV.

そのため警報信号を発した系は自系のμSVによ

択動作状態とさせる。 When the main monitoring device SV is installed and the #N system and #E system operate normally, the main monitoring device SV will select the additional monitoring device μSV unless an alarm signal is received from the system to be selected. A supervisory control signal SVS is sent out as selected by. Output OP in Figure 2
If the additional monitoring device μSV and the board Pt1 are designed in advance so that the own system is selected to be in the operating state when becomes "L", SVSEL in Figure 2 becomes "H", *SVPT
may be set to "L". An alarm signal may be applied to the #N system additional monitoring device from the #E system.
The potential is always set to "L", and the alarm signal is set to "H" potential. The same applies to the #E system to #N system.
Therefore, the system that issued the alarm signal is no longer an active system due to its own μSV, and the other system's μSV puts that system into a selected operating state.

give. In other words, the input terminal of the additional monitoring device μSV
SVSEL and *SVPT have the same potential. Therefore, the output of the exclusive OR operation circuit EOR in FIG. 2 is held at "L". For example, #N-based substrate Pt
1. In order to put Pt2 into the selected operating state, the alarm signal line input from the #E system board is cut off by SW2 and the potential "H" is applied. Therefore, from the perspective of the #N system additional monitoring device, the #E system has entered the alarm state and is sending a signal. To select #E system and release #N system, conversely disconnect switch SW3,
Apply "H" potential and close switch SW2.

い。 Since the configuration of the switches SW1 to SW3 in the present invention is to set the state of the other system to an alarm generation state during operation, the switches can have a configuration other than applying a predetermined potential. If the configuration of the additional monitoring device is determined so that the connection line open state becomes an alarm generation state, the connection line may simply be opened.

システムが格別高価にならない。 In this way, according to the present invention, the operation of the own system and other systems is monitored by the additional monitoring device, and when the main monitoring device is not installed or during a test, the operation or non-operation of each system can be selected as desired. This makes it easy to accurately grasp the status of each system. Furthermore, since the circuit configuration of each system including the additional monitoring device can be made the same, the system does not become particularly expensive.
