Abstract

PURPOSE:To display all trouble contents by sending troubles in a constant cycle when the troubles of a same class are continuously generated and transferring the trouble successively from the trouble with high priority order when the troubles of the different classes are simultaneously generated. CONSTITUTION:An alarm concerning the trouble to be generated in an exchange EX, which is set in a unattended station, is transformed to an alarm class (ten types, for example) according to the importance degree of the trouble and transferred to a maintenance station by a trouble transferring device ALSNDE. A trouble receiving device ALRCVE of the maintenance device receives, identifies and displays trouble information, which are just transferred, and a trouble class is stopped being transferred from the device ALSNDE. A trouble line to be connected up to the moment is opened and operation goes into preparation for the trouble reception of the class to be different from the above mentioned trouble class information. When the plural alarm classes are simultaneously generated, the alarm class is successively transferred. When the alarms of the same class are continuously generated, the alarm transferring is executed in the constant cycle.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a method for transmitting fault information in the form of a diamond pulse signal from a fault forwarding device when a fault occurs in a non-resident station, and a method in which multiple faults occur simultaneously. This relates to a fault forwarding method that sequentially forwards all of the data in the event of a failure.

[Conventional technology]

Conventional fault forwarding method... Faults that occur at non-resident stations are assigned alarm classes (main class) 0 to 7 (CQ-
C7) are assigned sequentially according to the fault type and severity, and each class is assigned subclasses 0 to 3 (SCO-8
C3) is subdivided into detailed information. That is, the alarm class is distinguished by changing the polarity of the two trunk lines (A-B line), and the subclass is distinguished by the type of signal sound, and information is created by combining eight alarm classes and four subclasses. Table 1 shows the polarity of the trunk line and the operation relay of the master station receiving device. Table 2 shows the signal tone indicating the subclass.
Shown below.

Table 2 below shows that under normal conditions, the receiving relays of the master station are the LC and LD relays.

Table 2 1. Symbol G in the trunk line polarity column...Earth air sending -... -48V sending +... +50V sending failure Transfer order is C091...・It is in the order of 7,
These classes are further divided into four subclasses: SCO
~3) According to the order of numbers, those with smaller numbers are transferred with priority. Therefore, items must be arranged in order, starting with the most important items.

For example, if a CI failure occurs while transmitting alarm class C3, the latter is of higher importance and is therefore switched to C1. Among C1, priority is given to subclasses with high importance. The fault receiving device identifies the information transferred from the fault forwarding device by type and degree of importance, and converts and displays the information into visible and audible signals.

[Problem to be solved by the invention]

In the conventional system, if there is a reception failure at the master station, an alarm is generated to that effect to alert maintenance personnel.

Maintenance personnel confirm what the alarm class is by checking the lamp display. Next, I inserted the handset into the signal tone monitor jack and learned the details based on the type of signal tone.

Conventional methods like this require maintenance personnel to operate each time a fault is received, and even if multiple faults occur at the same time, only the most important one is transferred, making it impossible to identify all faults. there were.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art, to receive and display fault information without the need for maintenance personnel's operations, and to automatically transfer all fault information issued by non-stationed stations one after another. The purpose of this invention is to provide a fault forwarding method that can identify faults.

(Means for Solving the Problems) A feature of the present invention is that alarms related to faults occurring within the exchange are classified into alarm classes (for example, 10
type) and transmits the fault information to the master station in dial pulse signal format.

When the failure receiving device receives and identifies the failure information being transferred and displays it, 1. Fault forwarding device (ALS NDE)
), the fault line that was previously connected is released, and preparations are made to receive faults of a class different from the fault class information mentioned above.

If multiple alarm classes occur at the same time, the alarm classes are transferred in order. or.

If alarms of the same class occur continuously, alarm transfers can be sent at regular intervals.

In this way, the present invention automatically performs fault reception, saves the trouble of maintenance personnel, speeds up the display of fault information, and also allows all different fault classes that occur at the same time to be received and displayed.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 shows the relay system of the fault forwarding system of the present invention, which includes a fault forwarding device (ALSNDE) that forwards faults to those installed at non-resident stations, and a fault line that is used by merging it with a general line. There is a failure forwarding additional unit (ALSAU). The maintenance station also has a fault receiving device (AL) that receives faults.
RCVE), fault display unit (AL
An additional failure reception unit (ALRAU) will be installed to be used in combination with the IND) and the general line.

2 and 3 are specific circuit diagrams implementing the present invention,
Further, FIG. 4 shows the operational sequence of fault forwarding.

The specific circuit configuration and operation of these fault transfer devices and receiving devices will be explained below.

A fault forwarding device (A
LSNDE) supplies earth air to the ports A1 to AIO. This ALSNDE connects 5 alarm class relays (C1 to C5) and 2
The alarm subclass relay (COO-C05) identifies the class of alarm to be selected and forwarded.

Furthermore, if earth air is supplied to multiple leads simultaneously from A1 to AIO, the earth air of the lead with the higher priority is selected first, that is, the alarm class with the higher priority is selected first, and this is After transferring the alarms and frames, the remaining alarms of the alarm classes are transferred. The geoki of the leads A1 to AIO have higher priority than the geoki of the younger leads than the geoki of the older leads.

Table 3 shows the correspondence between alarm class information A1 to A10 and alarm class relays and subclass relays for receiving alarm class information.

Table 3 If a fault classified as alarm class 1 or 5 occurs, water will be supplied to ALSNDE leads A1 and A5, but only relay C1 with the highest priority will operate due to the contact chain circuit of relays 01 to C5. do. Relay C1
When activated, the air in the A1 relay passes through the contacts of the C1 relay and activates the alarm subclass relay COo. In other words, failure forwarding information (alarm class 1) is extracted by the operation of class relay 〇〇〇, C1.

Alarm class 5 is for waiting. In the case of a fault forwarding dedicated line, there are two trunk lines (A and B lines) between the fault forwarding device (ALSNDE) and the fault receiving device (ALRCVE) of the maintenance station.
Since it is connected using
The relay was restored, then the STT relay was restored slowly, and A
Send earth air to the line and activate ALRCVE at the maintenance station. When ALRCVE is activated, relays A, AA, and B operate, and preparations for receiving fault class information are completed.

Then, the air passing through relay A is sent back to the B line of ALSNDE via the rk contact, indicating that preparations for receiving fault information are complete. In ALSNDE, S on the B line
The T relay operates and prepares to transfer the alarm. When relay ST operates, STA relay (not shown) operates. When relay STA operates, PGO of the pulse generation circuit
works. When relay PGO operates, PGI operates next. When relay PGI operates, relay PGO slowly recovers. When relay PGO is restored, relay PG1 is also slowly restored. When the relay PGI is restored, the relay PGO
works again. Relay pao.

Since the PGI repeats this kind of operation, the pulse speed of these relay contacts is 10 ± 1 pps, and the make rate is 33.
Intermittent pulses of ±3% can be obtained. Pulse transmission is approximately 60 seconds after ALRCVE startup confirmation (ST relay operation)
It will start after 0m5 has passed. The timing of this 600m5 is determined by relay PGO by a pulse counting circuit composed of relays PAS-PFS.

It is obtained by counting the pulses generated by the PGI six times. When the counting circuit counts six pulses, the relay PES operates. When relay PES operates, a pulse sending circuit made up of contacts of relays PGO and PGI is connected to line A through the contacts of relay PES, and pulses are sent from line A to ALRCVE. The number of pulses sent to ALRCVE is based on the alarm class information, and the number of pulses sent to ALRCVE is based on the alarm class information, and after relay PES operates in a counting circuit, relay PGO,
The number of pulses generated by the PGI is counted, and when the counted number of pulses matches the number of pulses specified to be sent by alarm transfer information, the PES relay is restored and the sending of pulses is stopped. In the case of alarm class "1", it is identified by the operation of class relays Coo and C1, so after relay PES of the counting circuit operates, if the pulse count is set to "1" pulse, counting relays PAS and PC are activated.

・SP relay: SP relay operates on the battery route. Table 4 shows the number of pulses sent out and the operating state of the counting relay at the time when the number of pulses was sent out.

When the SP relay operates, the contacts of the relay SP turn off the operation of the counting circuit relay PAS-PFS. Therefore, PES
The relay also recovers, so the pulse sending circuit stops sending out pulses. When the pulse from ALSNDE ends, the maintenance station's ALRCVE transfers the sent pulse to PA-P.
It is counted by the E-pulse counting circuit, and depending on the number of intermittent pulses, that is, the fault information, the relay AO of the alarm class receiving and accumulating circuit is

The RK relay operates by checking the utof5 format. When the RK relay operates, it is expanded to 1 out of 10 format by the contact of AO-A7, and AL1 to 10 are output.
Activate ALL of the relays. When the relay ALL operates, its contact all indicates the fault display unit ALIN.
The display lamp L1 of D is turned on to display the received failure information and notify the maintenance personnel. When the fault receiving device (ALRCVE) completes its fault information receiving operation, the RK relay operates and its contact rk disconnects the ground air that has passed through the A relay connected to the B line.

ALRCVE cuts off the ground air sent to ALSNDE's B line, so the ST relay is restored and the STA relay (not shown)
is slowly recovering. When the STA relay is restored, the relay SM is slowly restored. When the relay STA is restored, this ALSNDE cuts off the air that was being sent to the A line and connects the ALRCV at the maintenance station.
Restore E.

Also, during the time between when relay STA is restored and when relay SM is restored, ALSNDE operates alarm class memory relay A1 corresponding to alarm class "1'" (Coo, C1) of the alarm that has just been sent. A1
When the relay operates, class relay 01 and alarm subclass relay 〇〇〇 are restored, and the holding circuit of the memory relay is switched to the failure reception lead Al side and held until the source of the failure disappears. Relay STA, SM, Co.

When it is restored, relay AL operates. When the AL relay operates, the relay STT operates, and the ALSNDE recovers and prepares for the next scheduled alarm transfer information of alarm class II 5 It. Alarm class "5" can transfer the alarm class to the maintenance station using the same sequence as alarm class "1". If the same alarm continues, relay A1 is operating, so class relay 01 and subclass COO do not operate, so the same alarm is not transferred continuously.

If the same alarm transfer information continues, alarm transfer can also be transferred periodically. When ALSNDE is continuously sending the same alarm transfer information as the alarm that has just been sent to lead A1, that alarm class is stored in the A1 relay. Book ALSND
E is the time when relay A1 is operating, read PU and Δ
Monitored by a pick-up alarm pulse, for example every 5 minutes, provided to L. When relay A1 is operating and a pickup pulse is supplied to lead PU, relay AL
T works. 5 minutes after relay ALT operates,
Relay ALR operates with an alarm pulse supplied to L. When relay ALR operates, relay A1 is restored. If relay A1 is restored, alarm transfer lead A
1 is again regarded as new fault information, and the alarm class relay C1 and subclass relay COO operate, so that the alarm of the same alarm class can be transferred again. In the above embodiment, there are 10 alarm classes, but if there are more than 10 alarm classes, the number of alarm subclass relays is increased, and after sending out the medium identification pulse, the finger-to-finger Bose is 600 ns, and then the alarm transfer information (1 to 1
This can be made possible by sending a class 0).

〔Effect of the invention〕

As explained above, according to the present invention, if faults of the same class occur continuously, they are sent out at regular intervals, and if faults of different classes occur at the same time, they are sent out in order from the highest priority. You can transfer and display all fault details. Since a dial pulse signal format is used to send fault information, the line is temporarily released when reception of one fault class is completed, and preparations are made for reception of the next new fault. Therefore, failure information can be automatically received and displayed without any operation by maintenance personnel, which has a significant effect in simplifying the maintenance personnel's work and speeding up confirmation of failure information.
