Description

{Device for alarming a processor error of the keep-phone system}

The present invention relates to a processor failure alarm device of a key phone system, and in particular, when a main processor error occurs, the relay operates according to the main processor error determination signal to supply operating power to the alarm, thereby generating an alarm sound to the outside. The present invention relates to a processor failure alarm device for a key phone system, which promptly alerts an abnormal state of a processor to an external device and receives appropriate measures, thereby significantly improving the operational reliability of the key phone system.

In general, as the industrial society develops, information communication systems are widely used to transfer data from one point to another desired more appropriately and quickly. Such communication systems are usually homogeneous or heterogeneous communication devices which are geographically dispersed. In most cases, information devices are connected to a network to enable sharing and communication of resources. In the network, a switch is usually used to exchange information converted into an electrical signal with a counterpart, and is divided into a subscriber transmission connecting a subscriber and an exchange and a transmission between stations connecting an exchange period.

In particular, various types of systems are currently developed and used in the exchange system for subscriber transmission in terms of large facility capacity, and a simple exchange system for a building or a small subscriber among such exchanges is now widely used. In addition, such a conventional simple exchange system, for example, a key-phone, a board having necessary functions is inserted into a mother board, and such motherboards are combined in various numbers according to subscribers or other capacities. It is also possible to construct a rack.

Then, referring to the example of the conventional key-phone system as described above with reference to FIG. 1, a predetermined number of universal slots 71 into which external CO lines or extension cards 70A-N can be inserted, and this universal slot The backplane interface line 72 which is connected to each of the CO line or the extension card 70A-N inserted in the 71 and is a passage through which the signal to be switched is moved, and the backplane interface line 72 is connected. The function of the key phone 75 including a transformer 74 for separating a signal switched through the module jack 73 and switching of trunk lines or extension cards 70A-N inserted into the universal slot 71. It consists of a main processor 76 that can control the overall.

One end of the main processor 76 is connected to a key panel unit 77 capable of inputting a user's control signal and an LCD panel 78 displaying an operation state therein. The other end of the ring detect unit 79 and the handset 80 for detecting a ring signal input through the backplane interface line 72 is connected.

On the other hand, looking at the operation of the conventional key-phone system as described above, when a call signal is input from the external switch 81, the call signal is the corresponding of the universal slot 71 of the key phone 75 through the backplane interface line 72 It is input to the CO line card 70A and simultaneously with the ring detecting unit 79. At this time, the ring detecting unit 79 detects a ring signal carried in the input external call signal and rings a bell (not shown). Then, when the operator hears the ring tone and picks up the handset 80, the trunk line card 70A processes the voice signal of the other party's caller and sends it to the handset 80. Therefore, the operator confirms the extension number of the desired receiver from the other party's caller, and then presses the extension number through the key panel unit 77, and the main processor 76 recognizes this and allocates a channel to the corresponding extension card 70N. give. Then, a call connection signal is input from the trunk line card 70A of the universal slot 71 to the corresponding station card 70N. Accordingly, the call connection signal, for example, a voice traffic signal, is transmitted through a backplane interface line 72. The signal is matched via 74). Then, the call connection signal signal-matched by the transformer 74 is input to the wired telephone 82 via the module jack 73 to make a call between an external caller and an extension user. At this time, the main processor 76 displays the call state on the LCD panel 78 in letters or numbers through a display control signal.

However, since the conventional key phone system as described above is a main processor 76 using one CPU, there is no means for notifying the processor appropriately when an error occurs in the processor due to various causes of the system, for example, a power failure. The disadvantage was that the error recovery of the main processor took quite a while.

In addition, the conventional key phone system as described above does not alert the outside when an error occurs in the main processor, so the key phone system cannot perform the exchange function properly until the system administrator finds and takes action. There is also a problem that the operation reliability of the system is also significantly reduced.

The present invention is designed to solve the above problems, and when the main processor abnormality occurs, the relay is operated according to the main processor abnormality discrimination signal to supply the operating power to the alarm to generate an alarm sound to the outside, It is an object of the present invention to provide a processor failure alarm device for a key phone system, which promptly alerts the abnormal state of the main processor to the outside to receive appropriate measures, thereby significantly improving the operation reliability of the key phone system.

Another object of the present invention is to provide a processor failure alarm device for a key phone system that can be quickly processed by checking whether there is an abnormality of the main processor with a simple circuit configuration, thereby significantly improving the functionality of the key phone system.

In order to achieve the above object, there is provided a transistor which is turned on / off according to a main processor abnormality discrimination signal input from a main processor of a key phone, and a relay which performs a relay switching function according to the turn on / off signal of the transistor; And a battery for supplying power by a switching action of the relay, and an alarm for receiving an operating power from the battery switched by the relay and an alarm for generating an alarm signal informing the outside of the main processor.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

The device according to the present invention has a predetermined number of universal slots 2 into which external CO lines or extension cards 1A-N can be inserted, and a CO line or extension card inserted into the universal slot 2. A main processor 4 capable of controlling the overall function of the key phone 3 including switching functions of the 1A-Ns, and a main processor abnormality discrimination signal inputted from the main processor 4, for example, PFT_CLEAR ( A transistor 5 that is turned on / off in response to a PROCESSOR FAIL TRANSFER_CLEAR signal, a relay 6 that performs a relay switching action according to the turn on / off signal of the transistor 5, and a switching action of the relay 6 It is composed of a battery (7) for supplying power by the power supply, and an alarm (8) for receiving the operating power supplied from the battery (7) switched by the relay 6 to inform the outside of the abnormality of the main processor.

In this case, the PFT_CLEAR signal is a 'high signal' when the main processor 4 is normally operated, and is output as a 'low signal' when the main processor 4 is abnormally operated.

On the other hand, the key phone 3 as described above is connected to each of the trunk line or the extension card (1A-N) inserted into the universal slot (2), the backplane interface line (9) which is a passage through which the signal to be switched and; A transformer 11 for separating a signal switched through the backplane interface line 9 from the module jack 10 and a key panel connected to one end of the main processor 4 to input a user's control signal. A ring detector for detecting a ring signal input through the unit 12, the LCD panel 13 for displaying an internal operation state according to the display control signal of the main processor 4, and the backplane interface line 9 Part 14 is included.

In addition, a handset 15 is connected to one end of the main processor 4. In the present invention, the transistor 5 is described as only an NPN type, but any device capable of switching may be used.

Next, the operation and effect of one embodiment of the device of the present invention will be described.

First, when the key phone 3 is set up in the inventive device and the main processor 4 is normally operated, the main processor 4 sends the PFT_CLEAR signal to the 'high signal' through a certain port connected to the base end of the transistor 5. Will output Then, when the high signal indicating the normal operation of the main processor 4 is input to the base terminal of the transistor 5, the transistor 5 is turned off because the transistor 5 is of the NPN type, and the relay 6 maintains the current contact state. Therefore, since the operating power of the battery 7 is not supplied to the alarm 8, the alarm 8 does not generate a warning sound and the system administrator recognizes that the main processor 4 is currently operating normally.

At this time, when a call signal is input from an external exchange 16, the call signal is input to the corresponding trunk line card 1A of the universal slot 2 of the key phone 3 through the backplane interface line 9, and at the same time, ringdy It is also input to the text unit 14. At this time, the ring detecting unit 14 detects a ring signal carried in the input external call signal and rings the bell. Then, when the operator hears the ring tone and picks up the handset 15, the trunk line card 1A processes the voice signal of the other party's caller and sends it to the handset 15. Therefore, the operator confirms the extension number of the desired receiver from the other party's caller, and then presses the extension number through the key panel unit 12, and the main processor 4 recognizes this and allocates a channel to the corresponding extension card 1N. give. Then, a call connection signal is input from the trunk line card 1A of the universal slot 2 to the corresponding station card 1N, so that the call connection signal, for example, a voice traffic signal, is transmitted through a backplane interface line 9. The signal is matched via 11). Then, the call connection signal signal-matched by the transformer 11 is input to the wired telephone 17 via the module jack 10 to make a call between an external caller and an extension user. At this time, the main processor 4 displays the call state on the LCD panel 13 in letters or numbers through a display control signal.

Here, if an abnormality occurs in the main processor 4 during the process, for example, if the main processor 4 is abnormally operated due to an external shock, the PFT_signal is a 'low signal' to the base terminal of the transistor 5. Is approved. Then, since the transistor 5 is turned off, the relay 6 is operated to move the contact of the battery 7 to the contact of the alarm 8. Therefore, since the voltage of the battery 7 is supplied to the alarm 8, the alarm 8 generates an alarm sound to the outside.

Therefore, the external system administrator listens to the alarm sound of the alarm 8 of this key phone 3, recognizes that an abnormality has occurred in the main processor 4, and takes an appropriate action promptly, so that the key phone system can be quickly restored normally.

As described above, in the present invention, when the main processor abnormality occurs, the relay is operated according to the main processor abnormality discrimination signal to supply the operating power to the alarm, thereby generating an alarm sound to the outside, thereby causing the abnormal state of the main processor to As soon as the alarm is promptly received and the appropriate action is taken, there is an advantage of significantly improving the operation reliability of the key phone system.

According to the present invention, it is also possible to check the presence or absence of an abnormality of the main processor with a simple circuit configuration, so that the function of the key phone system can be considerably improved.
