Abstract

PURPOSE:To smoothly exchange or increase a unit by comparing a peculiar code for identifying the unit read out from a storing section with a reference signal and making a central device to send the reference signal until both coincide with each other. CONSTITUTION:When a unit 900 peculiar to one of plural device (1101)-(110-n) is exchanged or increased, a reference signal sent from a central device 100 is inputted to a comparing section 700. The peculiar code to be used for identifying the unit read out from a storing section 180 is compared with the reference signal at the timing given by a trigger signal outputted from an actuating section 150 installed to the unit to be exchanged or increased and a signal indicating the coincidence or discordance is outputted to the central device 100. The device 100 continuously sends the reference signal until both coincide at the comparing section 700. As a result, the unit exchange or increase is performed smoothly by automatically identifying the unit to be exchanged or increased.

[Industrial application field]

The present invention relates to a unit identification method in a center device when adding or replacing a unit to a remote communication device.

In recent years, in order to make the maintenance and operation of communication devices more economical, there has been an increasing demand for monitoring and controlling communication devices and changing the settings of device data from a central device located in a remote location. In this case, there is a need for a unit identification method that allows the addition or replacement of device units without any problems as the settings of device data are changed from a central device located at a remote location.

[Conventional technology]

FIG. 3 is a block diagram showing the configuration of an example remote control communication system.

FIG. 3 shows that a device 11 that functions as a center, and devices 1 to 2, I-3, and I4 as relay stations installed at intervals of about 100 kilometers (100 km) are connected to each other by working and backup transmission lines. An example of the configuration of a connected communication system is shown. In the figure, each device 1 to
If a part of any of the units installed in units 1 to 1-4 (for example, the unit of equipment 1 to 3) breaks down, or if the parts change over time, the unit will be replaced or added. In this case, a maintenance person was dispatched from the location of the devices 1 to 1 at the center to the location of the devices 1 to 3 to change the settings of the device data and replace or add units at the same time.

[Problem to be solved by the invention]

However, with the method of replacing or adding units as described above, if maintenance personnel set the wrong unit, they will have to be dispatched several times to complete the correct settings and complete the work, which is uneconomical. There was a problem.

Accordingly, an object of the present invention is to provide a unit identification method that allows installation or replacement of equipment units without any inconvenience.

[Means to solve the problem]

The above problem is solved by the configuration of the device shown in FIG.

That is, in FIG. 1, there are common unit sections 20 that are connected to each other by a transmission path and that process transmitted and received data respectively.
In a remote control communication system having a plurality of devices 110-1 to 110-n that transmit and receive control signal data to and from the center device 100, the plurality of devices 110-1 to 110-n include When replacing or adding any of the unique units 900 of 110-n, an activation unit 15 generates a trigger signal at a fixed timing to the unit to be replaced or added.
0, and a storage unit 180 that stores a unique code for identifying a unit to be replaced or added.

Further, a reference signal sent from the center device 100 for identifying the unit to be replaced or added is inputted to the common unit section 200, and the reference signal is inputted to the common unit section 200 at the timing given by the trigger signal output from the activation section 150 of the unit to be replaced or added. A comparison unit 700 is provided that compares a unique code for identifying a unit read from the storage unit 180 with a reference signal and outputs a signal indicating whether the two match or do not match.

Then, the center device 100 is configured to send out the reference signal until the comparator 700 matches the two.

[For production]

In FIG. 1, when replacing or adding a unique unit 900 of any one of the plurality of devices 110-1 to 110-n, a comparison section 700 provided in the common unit section 200 of the device to be replaced or added. , the reference signal sent from the center device 100 is input, and a unique unit is read out from the storage unit 180 at a timing given by a trigger signal of the output of the activation unit 150 provided in the unit to be replaced or added. The reference signal is compared with the reference signal, and a signal indicating whether the two match or do not match is output to the center device 100. Then, the reference signal is sent from the center device 100 until the comparator 700 matches the two.

As a result, when it becomes necessary to replace or add a unit to the apparatus, the replacement or addition unit can be replaced or added without any trouble by automatically identifying the replacement or addition unit.

〔Example〕

FIG. 2 is a block diagram showing the configuration of an apparatus according to an embodiment of the present invention.

The same reference numerals indicate the same objects throughout the figures.

For example, assume that a unit failure has occurred in devices 1 to 3 shown in FIG. 3 and the unit is to be replaced. At this time, from device l-1 having a function as a center to device 1
In steps 3 to 3, information (reference data) such as the unit code and settings of switches (not shown) are sent out using a backup transmission line. At the same time, the maintenance staff goes from the location where devices 1 to 1 with center functions are installed to the location where devices 1 to 3 are installed, and selects the devices! - Replace the failed unit in step 3 with a new unit and set it up. This replaced unit is shown at 9 in FIG.

On the other hand, devices 1 to 1 are placed in the register 5 provided in the common unit 2.
The reference data sent from the register 5 is input and temporarily held in the register 5. Then, the reference data temporarily held in the register 5 is transferred to the register 6 by a trigger signal outputted at regular intervals from the starting circuit 10 provided in the replaced unit 9. Furthermore, the reference data temporarily held in the register 6 is applied to the comparator circuit 7 by the trigger signal output from the starting circuit 10 again.

In addition, the register 11 of the replacement unit 9 temporarily stores the unit code of the unit to be replaced, that is, the own unit, and from this register 11, the address indicated by the output signal of the address generation circuit 8 provided in the common unit 2 is stored. The stored unit code (this unit code indicates the unit code of the own unit to be replaced) is output and applied to the other input terminal of the comparator circuit 7.

Comparison circuit 7 compares the input from register 6 (reference data) and the input from register 11 (unit code unique to the replaced unit). When the two match, for example, a signal of "l" is output, and when they do not match, a signal of "0" is output.
” signal is sent to the center device 11.The center devices 1 to 1 receive this signal, and when the signal is “l”, the devices 1 to 3 recognize that the replacement unit has been correctly set. .Also, when the received signal is "0", it is recognized that the settings of the replacement unit are incorrect, and the maintenance personnel dispatched to equipment 1 to 3 are notified by telephone etc. of the erroneous operation, and the system waits until the correct settings are made. Repeat the above operation.

Note that the exchange unit 9 can be made of, for example, an E"FROM. Furthermore, the common unit 2 can be made of, for example, an LSI.

Also, the output of register 6 in common unit 2 is transferred to register 5.
The devices that provide feedback are center devices 1 to 1.
When the reference data is not sent from the starting circuit I.
This is to prevent the contents temporarily stored in the register 6 from being lost by applying a trigger signal from O to the register 6 and outputting the contents temporarily stored in the register 6.

The common unit 2 mentioned above is connected to all devices (in this case it is
~1~4). Further, the same operation as described above is performed not only when a unit is replaced but also when a unit is added.

As a result, when it becomes necessary to replace or add a unit to the apparatus, the replacement or addition unit can be replaced or added without any trouble by automatically identifying the replacement or addition unit.
