Description

[Detailed Description of the Invention] [Summary] An alarm signal control unit collects alarms generated in an exchange system to a system console using multi-frequency signals, and the alarm signal control unit of the system console collects alarms generated in an exchange system to an alarm display unit using other multi-frequency signals. This is an alarm collection and display method that transmits and displays alarms.

FIELD OF INDUSTRIAL APPLICATION] The present invention relates to an alarm collection/display method for an exchange system that has an easy configuration and allows alarms generated in the exchange system to be collected and displayed even in remote locations.

[Prior art] Regarding a system that exchanges a plurality of subscriber telephones, the configuration in which the operating status of the system is monitored using a system console is described in the fourth example.
It was as shown in the figure. That is, the switching system 1 performs connection switching for subscriber telephones (not shown) under the control of a central control unit 2 (CCC). The monitoring system console 4 is connected to the exchange system 1 by connection lines, which are hardware failure notification lines 31 (multiple lines) of the exchange system and software failure notification lines 32 of the central control unit 2. The exchange system has racks 11.
12.- are provided, and predetermined devices are controlled by the central control device 2 to perform various operations. Frame 11.12・
... have units 11-1 and 11-2-1 respectively.
1-n, 12-1.12-2'--42-n are provided.

Alarm signal lines for notifying hardware failures for each unit are grouped together as terminals □f3, 14, 15, 16, and connected to the connection line 31 after being concentrated by the jumper field 17. Separate signal lines were required for each unit's hardware failures, such as power supply package failures, blown fuses, etc. Each sensor in the unit had a switch to open/close between it and the ground potential, so jumpers were required. After concentrating the lines in field 17, connect h”t! Since the system console 4 is connected to the system console 4 through the VA 31, it is necessary to provide a receiving circuit for each connection line, which requires potential connection/disconnection between -48V and ground potential within the system console 4.

In the system console 4, the central control unit 2
It has a circuit 23 for monitoring the software of the CC (CC), and is monitored under the control of a microprocessor 21 (MPU). When the microcomputer 21 (MPU) receives an alarm signal from the alarm reception circuit 22 and the software monitoring circuit 23, it controls the relay drive circuit 24 and closes predetermined contacts of the relay contacts 26-1 to 26-n. Relay contact 27 is for an alarm bell. Further, 25 indicates a negative terminal (earth potential) of the DC power supply.

Furthermore, an alarm display section 6 is provided to display that the system console 4 has received various alarm signals, and a display signal line 5 connects the alarm display section 6. That is, the microprocessor 21 (MPU) controls a predetermined relay contact 26 so as to cause an indication on the display lamps 31-1 to 31-n of the alarm display section 6 or the alarm bell 32 in response to the received alarm signal.
．． 27 is closed.

[Problems to be Solved by the Invention] Conventional alarm collection and display methods have the following problems. i.e. exchange system 1 and system console 4
An extremely large number of lines are required for the hardware failure notification line 31 between the two and the display signal line 5 between the system console 4 and the alarm display unit 6. This is because one connection line and one display line are required for each type of alarm to be collected and displayed, resulting in an enormous amount of hardware. Furthermore, since the fault notification line 31 and the display signal line 5 operate at -48V and ground potential, respectively, the voltage used is high, making it difficult to use a semiconductor integrated circuit with a simple configuration.

The purpose of the present invention is to improve the above-mentioned drawbacks, and to effectively collect and display alarms with a simple configuration by connecting the exchange system, system console, and alarm display section (!) with a small number of connecting wires. The goal is to provide a method.

Means for Solving Problem E] FIG. 1 is a diagram showing the basic configuration of the present invention. In Fig. 1, a switching system 1, a central control unit 2, a system console 4 (STCNS), an alarm display m 6 (ALI
It is the same as the conventional method that the system console 4 monitors alarms generated in the exchange system 1, and displays the alarms on the alarm display section 6 according to instructions from the system console 4.

The present invention is directed to the alarm collecting part of the exchange system in FIG. -1, 7-2- has a multi-frequency signal oscillator 8-1,
The alarm signal collection controller 8-2 includes a receiver 8-2 and an alarm signal collection controller 8-3. A pair of wires 33 connects the alarm collection target unit 7-1 and the like to the system console 4. The system console 4 includes multi-frequency signal oscillators 29-1, 29

The alarm display section 6 includes a multi-frequency signal receiver 41 and an alarm signal display control section 40, and the system console 4 and the alarm display section 6 are connected by a pair of wires 51.

[The alarm collecting section 7-1, 7-2- of the action exchange system detects the occurrence of an alarm by using various sensors similar to conventional ones, and sends the alarm signal to the alarm signal control section 8-3, for example, via the multiplexer MPX. Collected by the processor. In the system console 4, the multi-frequency signal oscillator 29-1 is controlled by the alarm signal transmission/reception control section 21.
Is the alarm collected part of exchange system 1? -1, 7-2・
- is polled for alarm collection, and when the alarm signal collection control section 8-3 detects it, the collected alarm signal is sent out using the multi-frequency signal oscillator 8-1. This signal is transmitted to the system console 4 via the pair of wires 33 and received by the multi-frequency signal oscillator 28. Next, the alarm signal transmission/reception control unit 21 of the system console 4 analyzes the received alarm signal, instructs the target 33-1 to be displayed on the display unit 6, etc., starts the multi-frequency signal oscillator 29-2, and The signal is received by the multi-frequency signal receiver 41 of the alarm display unit 6 via the signal line 51. The alarm signal display control unit 40 selectively displays a predetermined target lamp 33-1 or the like based on the received signal.

[Embodiment] FIG. 2 is a diagram showing a connection section between the alarm collecting section 7-1- and the pair wire 33 of a switching system as an embodiment of the present invention.

In FIG. 2, a code signal, for example 000, assigned to the alarm collecting section 7-1 is transmitted from the system console to the alarm collecting section 7-1 using a multi-frequency signal. The collection target unit 7-1 receives the code signal together with other collection target units, and the alarm signal collection control unit 8-3 receives rOOOJ.
Only alarm 1 is set up as a mode in which signals can be sent. Then, a predetermined alarm signal is encoded and sent as a multi-frequency signal to the system console.

FIG. 3 is a diagram showing the formant of an alarm signal.

In the example of the alarm signal shown here, it is composed of an address 50 of the part to be collected, an alarm generation unit number 5■, and an alarm type code 52.

As an example of a signal, let us say 000 B XY.

Here, OOO is the address number of the part to be collected, B is the alarm generation unit number (displayed in hexadecimal), and XY is the alarm type code.

In FIG. 1, the IC in the alarm display section 6 represents an interface adapter, which controls the light emitting diode of the PMJ to light up if the received signal indicates a major power failure. SMJ, SMN are software related, HMJ
, HMN is used to indicate hardware-related failures.

[Effects of the Invention] As described above, according to the present invention, since a multi-frequency signal is used when transmitting an alarm signal, a large number of types of alarm signals can be provided. Since only a pair of wires is used as a transmission line capable of transmitting and receiving multi-frequency signals, a pair of wires can be extended over a long distance. As the hardware for transmitting and receiving alarm signals can be made from telephone parts and relay circuits can be omitted, it is easy to miniaturize the system using integrated circuits even when using many types of signals.
