Abstract

PURPOSE:To obtain the alarm collection and control system easily coping with the unit constitution without need of a special cable by utilizing a power cable provided to each unit accommodated in a shelf to apply alarm collection control. CONSTITUTION:Power cables 51, 52,... have many conductors and a multi-pin type connector is fitted to both ends. The cable 61 interconnects a device component unit of a section 1 and a fuse section 9 to supply power to the unit. Similarly cables 52, 53,... interconnect device component units of sections 2, 3,... and the fuse sections 9,... to supply the power to the units. The fuse section 2 has fuses 91, 92,... to each unit, receives power from power supply sections 11, 12 and supplies power to each unit through each fuse. Since multi-core type cable and a multi-pin type connector are employed, an alarm panel output of each unit and a control signal are sent by using idle conductors of the cable and idle pins of the connector.

Description

[Detailed Description of the Invention] [Summary of the Invention] Regarding an alarm collection and control method in a communication device configured by combining various units and storing them in one shelf, there is no need for special cables and the system remains stable even if the unit configuration changes. With the aim of providing an alarm collection and control method that can easily handle the above, we have developed an alarm collection and control method for a communication device in which various device configuration units are selected according to the target communication device and housed in a shelf. The alarm panel of each unit and the alarm collection section housed in the shelf are connected by using the empty pins of the power cable using a multi-pin connector and the conductive wires connected to the power cables that connect the power supply device housed in the shelf and each of the units. was connected to transmit alarm and control signals.

[Industrial application field]

The present invention relates to an alarm collection and control method in a communication device configured by combining various units and storing them on one shelf.

There are devices that house various necessary units on one shelf to form one communication device. The units housed in the shelf G vary depending on the intended communication device, but some are common, such as a power supply and an alarm unit.

The present invention relates to this alarm section.

[Conventional technology]

FIG. 4 shows an example of this type of shelf. The shelf 10 is divided into a plurality of sections 1, 2, 3, . . . by a plurality of shelf boards and partition plates.
..., and each section accommodates various device configuration units. In the case of 32MHz optical communication equipment, the units accommodated in sections 1 and 3 are tip station equipment, and the units accommodated in sections 2 and 4 are
The unit housed in section 5 and 6 is a 32 MHz multiplex converter, the unit housed in section 5 and 6 is a 6 MHz branch unit, etc.
...is... The type, number, etc. of these units vary depending on the target communication device, but some remain unchanged for each communication device. These include the alarm collector housed in section 8, the fuse section housed in section 9, and the power supply section housed in sections 11 and 12.

Each of the various units in categories 1 to 7 is equipped with an alarm panel, and the alarm collection unit in category 8 collects alarms generated by these alarm panels. In FIG. 5, reference numerals 21 to 27 are the alarm panels of the units of categories 1 to 7, 30 is the alarm interface section of the alarm collection section of section 8, and 32 is a cable connecting these alarm panels and the alarm interface section. Cable 32 connects signal line 18
It is a set of multiple connectors 34, such as 18 pins, 24 pins, etc., and is equipped with a predetermined number of connectors 34 having multiple pins, such as 18 pins and 24 pins, at predetermined intervals. It is connected to the interface section through the connector.

Normally, alarms are generated from each part of each unit, but they are logically summed and combined into one pin, one
It is sent out through two signal lines. Therefore, one of the signal lines corresponds to one unit, and the alarm collection section recognizes whether or not there is an alarm from the unit (regardless of the type of alarm). This signal line is also used from the alarm collection section to control the alarm test of each unit.

[Problem to be solved by the invention]

Conventional alarm collection and control is performed through a cable 32 having a predetermined number of multi-pin connectors attached at predetermined intervals, as shown in FIG. For this reason, a special cable 32 is required, and if the unit configuration on the shelf changes, the number and spacing of connectors must be changed accordingly, and it is necessary to use a cable with connectors attached to match the configuration. , there is the inconvenience that general-purpose products cannot be used.

SUMMARY OF THE INVENTION An object of the present invention is to improve these points and provide an alarm collection/control system that does not require special cables and can easily adapt to changes in unit configuration.

[Means to solve the problem]

As shown in FIG. 1, in the present invention, each unit l.

2, power cables 51, 52. ...
...Transmit alarm and control signals using vacant lines.

A power cable has a large number of conductors, and a multi-pin connector is attached to both ends. The power cable 51 is classified as Category 1.
The device configuration unit is connected to the fuse section 9, and power is supplied to the unit. Similarly, power cables 52, 53.
. . . indicates the device component unit and fuse portion 9 of category 2, the device component unit and fuse portion 9 of category 3, etc.
... to supply power to these units.

The fuse part 9 is a fuse 91.92 for each unit.
．． . . . They receive power from the power supply sections 11 and 12 and send it to each unit through each fuse.

Power cables are multi-core, and connectors are usually multi-pin, with some empty pins and conductors. The alarm panel output and control signals of each unit are transmitted using these empty pins and empty conductors.

[Effect]

In the present invention, collection and control of alarms is performed using the power cables of each unit housed in the shelf. Since a power cable is always provided for each unit, alarm collection and control can be carried out reliably for each unit without omission, and there is no need for a special cable for alarms unlike in the past. Even if the type and number of units change, the length, number, etc. of the power cables are changed accordingly, so alarm collection and control can be performed reliably through the changed power cables.

〔Example〕

An example of the structure of the connectors 41 to 48 of the power cable is shown in the second example.
As shown in the figure. As shown in the figure, it has 12 x 3-36 pins, of which 3+2+3=8 pins are used to generate 48V.
, power supply ground G is supplied using 3+3+2=8 pins, and signal ground E is supplied using 3+2+3=8 pins. Blank columns are empty pins. In the present invention, this empty pin is used to perform alarm collection control. 5YS-G, R

The G pin is sent to the alarm collector 8 through another connector. If a connector of the same type is used as this other connector, the required number of pins would be 3×7=21 pins, but this connector has 36 pins, so one set of connectors is sufficient. Note that the alarm collection control pins of the power connectors 48 and 68 for the alarm collection unit are left vacant.

The empty pins on the connector are used to supply AC power if it is also required. A connector having the configuration shown in FIG. 2 is often used as a power connector for this type of device.

〔Effect of the invention〕

As explained above, in the present invention, alarm collection control is performed using the power cable provided in each unit, so a special connector for alarm collection control for each unit is not required. In addition, even if the mounting state changes, a power cable is always provided for each unit, so alarm collection and control can be performed through it, which solves the problems of the conventional method, simplifies maintenance, and reduces costs. I can do it.
