Abstract

PROBLEM TO BE SOLVED: To make it possible to easily particularize a signal transmitting unit by outputting with deviation while keeping the original state of signal arrangement when the signals pass through the signal transmitting portion and by shifting the signal position as the number of transmitting portions of passing signals increases. SOLUTION: A connection pin 25A of an output connector 22 connected to a signal output terminal for equipment disturbance such as an added unit 15 is connected to a connection pin 25D of an output connector 22 through a connecting pin 25A of an input connector 21 of an added unit 14, a connecting pin 25B of an input connector 21 of an added unit 13, a connecting pin 25C of the output connector 22 and a connecting pin 25C of an input connector 21 of a signal transmission substrate 17 of a basic unit 12. That is, the added unit 15 passes three signal transmitting substrates 17 until it reaches the processing substrate 16 of the basic unit 12 and thus it is deviated three times. When outputting from the signal transmitting substrate 17 of the basic unit 12, it outputs from the connecting pin 25D.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the occurrence of a fault in a specific unit of an electric device (for example, a communication device such as an electronic exchange which can be increased or decreased in units depending on the capacity of a line), which can be appropriately expanded by an expansion unit. The present invention relates to a signal transmitting unit specifying method of an electric device for specifying a transmitting position of a signal when a signal such as a signal is transmitted, and an electric device with a signal transmitting unit specifying function.

[0002]

2. Description of the Related Art In an electronic exchange or the like which is increased or decreased in units according to the capacity of a line, equipment failure may occur. Here, the device failure refers to a blown fuse for supplying power to an internal package, an air cooling fan mounting portion, or the like, which is an additional unit that is added to a plurality of basic units.
Refers to hardware failures such as power failures and fan rotation abnormalities.

[0003] When a device failure occurs, there is generally known a device in which measures are taken to identify the content and location of the failure.

FIG. 2 shows an electronic exchange 1 in which the above measures are taken. In this electronic exchange 1, extension units 3, 4, and 5 are connected in cascade to a basic unit 2. Here, an example in which three amplification units 3, 4, and 5 are connected to the basic unit 2 is shown, but four or more additional units may be connected.

[0005] A board 6 is attached to the basic unit 2. The substrate 6 is a device for specifying the content and the location of the device failure and taking measures against it. This board 6 is directly connected to each of the extension units 3, 4, and 5. When a failure occurs in any of the extension units 3, 4, and 5, the information is directly transmitted to the board 6, and the details of the failure and the location of the failure are specified.

[0006]

However, in the above-mentioned prior art, since all the extension units 3, 4, and 5 are directly connected to the board 6 of the basic unit 2, the input connected to the board 6 The number of signal lines increases. As a result,
There is a problem that the load of signal processing increases and the circuit scale increases accordingly.

Further, since the size of the substrate 6 of the basic unit 2 is constant and cannot be increased without limit,
There is a problem that the number of extension units that can be added to the basic unit 2 is limited to the number of input signal lines that can be connected to the board 6.

[0008]

According to a first aspect of the present invention, there is provided a method for specifying a signal transmission unit of an electric device, comprising: a basic unit located at one end; One or a plurality of additional units which are connected to each other, and a signal transmission which is provided in each of the basic unit and each of the additional units and transmits a signal to the basic unit when a signal is transmitted from one of the additional units. And each signal transmission unit,
It has the same number or more signal transmission paths as the number of extension units connected in cascade, and arranges one or more signals input from the other in each of the signal transmission paths each time the signal is transmitted through the signal transmission section. The signal is shifted to one side while maintaining the same, and the position of the signal is shifted as the number of passing signal transmission units increases, and the signal transmission unit is specified at the shifted position.

With the above configuration, when a signal from the extension unit is input to the signal transmission unit, the signal is shifted and output by a predetermined width while maintaining the arrangement state with other signals.
Then, the shift amount of the signal corresponds to the number of signal transmission units passing therethrough. In other words, if the signal is from an extension unit in the vicinity of the basic unit, the number of signal transmission units passing therethrough is small, and the shift amount when transmitting the signal to the basic unit is small. The further away the extension unit is from the basic unit, the greater the number of signal transmission units through which signals from the extension unit pass, and the greater the amount of shift when transmitting the signal to the basic unit. By associating the magnitude of the shift amount with each extension unit, the extension unit that has transmitted the signal can be specified.

According to a second aspect of the present invention, there is provided an electric device with a signal transmitting unit identifying function, wherein a basic unit located at one end and a cascade connection from the basic unit to the other are provided.
Or a plurality of extension units, and a signal transmission unit that is provided in the basic unit and each extension unit and transmits a signal to the basic unit when a signal is transmitted from any of the extension units, Each signal transmission unit has the same number or more signal transmission paths as the number of extension units connected in cascade, and the input side and the output side of this signal transmission path are connected while being shifted from each other while maintaining their arrangement state. It is characterized by having.

According to the above configuration, the signals transmitted from each extension unit are shifted when passing through the signal transmission unit.
Therefore, as in the first aspect, by associating the magnitude of the shift amount with each extension unit, it is possible to identify the extension unit that has transmitted the signal.

Further, when a signal (for example, an alarm signal for notifying the occurrence of a failure) is transmitted from any of the extension units 13, 14, 15, each of the units 12, 13, 14, 15 transmits the signal to the basic unit. 12 processing substrates 16
A signal transmission board 17 is provided as a signal transmission unit for transmitting the signal to the control unit.

The signal transmission boards 17 provided in the units 12, 13, 14, 15 all have the same configuration, and are specifically as shown in FIG. (A) in the figure
(B), (C) and (D) are the signal transmission boards 17 respectively. The signal transmission board 17 includes an input connector 21 and an output connector 22. Each connector 21, 22 is provided with five connection pins 25A to 25E. The first to fourth connection pins 25A to 25D are used as signal transmission paths for specifying a signal generation unit. The reason why the number of signal transmission paths is set to four is that three extension units 13, 14, and 15 are connected, and when four or more extension units are connected, the number of pins or the number of pins corresponding to the number is set. Signal transmission board 17 with pins
Is used.

Each connection pin 25A on the input connector 21 side
25D are connection pins 25A on the output side connector 22 side.
25D are not connected as they are, but are shifted from each other. That is, the input side and the output side are connected to be shifted from each other while maintaining the arrangement state of the pins. Specifically, the first connection pin 25A on the input connector 21 side is connected to the second connection pin 25 on the output connector 22 side.

5C, the third connection pin 25C is connected to the fourth connection pin 25D,
Each is connected. The first connection pin 25A of each output connector 22 is connected to a signal output terminal (not shown) for outputting a device failure signal or the like of the unit 12, 13, 14, 15 to which the signal transmission board 17 is attached. ing.

Fifth connection pin 25 on input connector 21 side
E is directly connected to the fifth connection pin 25E on the output side connector 22 side. Further, the fifth connection pin 25E on the input side connector 21 side has an output terminal (shown in the figure) for displaying a signal such as a device failure occurring in the units 12, 13, 14, 15 to which the signal transmission board 17 is attached. Z)
It is connected to the.

Each signal transmission board 17 is connected to each other by a connection cable 26 having the same pin assignment. The connection cables 26 all have the same configuration.
That is, it is constituted by five signal lines 26A to 26E,
The connection pins 25A to 25E of the output side connector 22 are connected to the connection pins 25A to 25E of the input side connector 21, respectively.

Each signal transmission board 17 is connected to each connection cable 26
When the connection is made as shown in FIG. That is, the first connection pin 25A of the output connector 22 connected to the signal output terminal of the third extension unit 15 such as a device failure is connected to the first connection pin 25A of the input connector 21 of the second extension unit 14,
The second connection pin 25B of the output side connector 22, the second connection pin 25 of the input side connector 21 of the first extension unit 13
B, the third connection pin 25C of the output side connector 22 and the input side connector 21 of the signal transmission board 17 of the basic unit 12
Is connected to the fourth connection pin 25D of the output side connector 22 through the third connection pin 25C. That is, since the third extension unit 15 passes through the three signal transmission boards 17 before reaching the processing board 16 of the basic unit 12, the third extension unit 15 is shifted three times (shifted by three times), and the signal of the basic unit 12 is shifted. When the signal is output from the transmission board 17, the signal is output from the fourth connection pin 25D.

Similarly, the signal input from the first connection pin 25A of the output side connector 22 of the second extension unit 14 is shifted twice (shifted twice), and the signal transmission board 17 of the basic unit 12 is shifted. In this case, the signal is output from the third connection pin 25C. Further, the signal from the first extension unit 13 is output from the second connection pin 25B on the signal transmission board 17 of the basic unit 12.

In each of the extension units 13, 14, and 15, the signal transmission board 17 is connected only to a signal output terminal such as a device failure and a content display signal output terminal such as a device failure. In the basic unit 12, the signal transmission board 17 is connected to each of the signal output terminals, and the output side connector 22 is connected to the processing board 16. In this processing board 16, the occurrence position and the content of the failure are specified. It has become so.

On the other hand, when the electronic exchange 11 having the above configuration is further added, the electronic exchange 11 is connected in cascade behind the third additional unit 15. At this time, as the signal transmission board 17 attached to each extension unit, a board whose signal transmission path is set to be larger than the number of extension units is used.

[Method of specifying signal transmission unit of electric equipment]
Next, a signal transmitting unit specifying method using the electronic exchange 11 having the above configuration will be described.

This signal transmission unit specifying method is to pass one or a plurality of signals input from the connection pins 25A to 25E of the input side connector 21 of the signal transmission board 17 constituting each signal transmission path through the signal transmission board 17. Each time, the output signal is output from each of the connection pins 25A to 25E of the output-side connector 22 while being shifted by one pin while maintaining the arrangement state, and the shift amount is increased as the number of passing signal transmission boards 17 increases. This method uses the magnitude of the shift amount to specify the additional units 13, 14, and 15 that have transmitted the signal.

Specifically, this is as based on the above-described configuration, and the first connector 21 of the input side connector 21 of the signal transmission board 17 is provided.
The third connection pins 25A to 25C are shifted by one pin, and the second to fourth connection pins 25B
25D. Therefore, the input side connector 21
The signals input to any of the first to third connection pins 25A to 25C are shifted by one pin and output from the second to fourth connection pins 25B to 25D of the output connector 22.

Thus, for example, the third extension unit 15
When a signal, such as a device failure, is generated, the signal is first input to the first connection pin 25A of the output side connector 22 of the signal transmission board 17. The signal input to the first connection pin 25A is transmitted to the second extension unit 14, the first extension unit 13, and the basic unit 12 via the connection cable 26.
Are input to the processing substrate 16 after passing through each signal transmission substrate 17. That is, by passing through the signal transmission board 17 three times,
The signal is shifted by three pins and is output from the fourth connection pin 25D of the output side connector 22 of the signal transmission board 17 of the basic unit 12. Similarly, the signal from the second extension unit 14 is shifted by two pins and output from the third pin 25C, and the signal from the first extension unit 13 is shifted by one pin and the second connection The signal is output from the pin 25B. Thereby, each connection pin 25A of the output side connector 22 of the signal transmission board 17 of the basic unit 12
~ 25D is one-to-one with each unit 12,13,14,15

Is a signal from the basic unit 12, a second connection pin 25B is a signal from the first extension unit 13, and a third connection pin 25C.
Is the signal from the second extension unit 14, the fourth connection pin 25
D is recognized as a signal from the third extension unit 15. That is, the processing board 16 specifies which of the additional units 13, 14, 15 from which of the connection pins 25A to 25D the signal is output from.

At the same time, a signal indicating a specific content such as a fault that has occurred is input to the fifth connection pin 25E of the input connector 21 of the signal transmission board 17. This signal is input to the processing board 16 of the basic unit 12 via a path different from the position information via each fifth connection pin 25E of each signal transmission board 17.

In the processing board 16, the first to fourth connection pins 25 A to 25 D of the output side connector 22 of the signal transmission board 17 of the basic unit 12 are used to determine which extension unit 13, 14, 1
5 is specified, and the content of a failure or the like is specified by a signal from the fifth connection pin 25E.

Have the same configuration, the signal transmission board 17 attached to the basic unit 12 is used. In particular, it is not necessary to increase the size, and the device can be reduced in size and weight.

Signals from the units 12, 13, 14, and 15 are transmitted to the signal transmission board 17 of the basic unit 12 by
The first to fourth connection pins 25A of the output side connector 22
-25D are assigned in one-to-one correspondence, so that a signal transmission unit can be easily specified by a signal from any of the connection pins 25A-25D.

Further, a signal indicating the details of the device failure and the like is transmitted to the processing board 16 through a signal transmission path including the fifth connection pin 25E. Can be specified. As a result, it is possible to quickly and optimally take measures thereafter.
