Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. 2 is a block diagram of an abnormality alarm device in the exchanger according to the present invention. As shown in FIG. 2, the abnormality alarm device in the exchange according to the present invention includes an exchanger 60, a DTMF detector 30, a CPU 80, a power detector 90, a segment controller 100a to 100f, The LED controller 110, the speaker controller 120, the switch 130, and the alarm panel 150 is composed of. The exchange 60 sends a DTMF message via a line port. The DTMF detection unit 70 receives an analog DTMF message sent from the switch 60 through the line port, converts it into a digital DTMF message, and sends it out. The CPU 80 receives the DTMF message of the digital form sent from the DTMF detection unit 70, analyzes the received message, and sends out a suitable control signal and message. The power detector 90 detects a power supply state of the exchanger 60 and transmits a power supply state detection signal to the CPU 80. The segment controllers 100a to 100f receive the control signal and the message sent from the CPU 80 and display the corresponding message on the segment indicator of the alarm panel 150. The LED controller 110 receives the control signal sent from the CPU 80 and controls the LED of the alarm panel 150 according to the control signal. The speaker controller 120 receives the control signal transmitted from the CPU 80 and controls the speaker of the alarm panel 150 according to the control signal to determine the period and frequency of the speaker to drive the speaker as well as the switch unit 130. When the control signal to turn off the speaker is received from the CPU), the CPU 80 sends a notification signal indicating that the control signal to turn off the speaker is received. The switch unit 130 includes a speaker off switch connected to the speaker controller 120 to prevent the speaker from operating, and detects the state of the speaker off switch and the dial and transmits a corresponding control signal to the speaker controller 120.

Referring to the operation of the abnormal alarm device in the exchange configured as described above in detail as follows.

The exchanger 60 periodically converts the abnormal state into a dual tone multifrequency (DTMF) signal and sends it out through the line port. The DTMF detecting unit 70 receives the analog DTMF signal transmitted from the exchanger 60, converts it into a digital form composed of 1 byte, and sends it to the CPU 80 side. The CPU 80 receives a message composed of a 1-byte frame sent from the DTMF detection unit 70. An abnormality in the transmission line depends on whether or not a digit “B” is written in the first bit position of the frame. Determine the presence or absence, read the second bit digit, determine the color of the LED, the period and frequency of the speaker, and judge the type of the abnormal condition according to the message indicating the type of the abnormal condition of the system written from the third to eighth bit digits. . Digit “B” is written in the first bit place of the CPU 80, and a digit is written in the second bit place indicating the message to turn on the yellow LED or the red LED, and the third bit place to the eighth place. In case of confirming the written message, the designated control signal is sent to the LED control unit 110 and the speaker control unit 120 according to the digits written in the second bit, and is written over the third to eighth bit positions. According to the contents of the message, the corresponding segment controllers 100a to 100f are selected from the six segment controllers 100a to 100f to deliver a message indicating the type of abnormal state of the received system. If the CPU 80 confirms that the digit "B" is not written in the first bit position, it determines that an error has occurred in the transmission line and indicates a message indicating that an error has occurred in the transmission line and a control signal for displaying the message. At the same time as the segment control unit (100a ~ 100f), and transmits the appropriate control signal to the LED control unit 110 and speaker control unit 120. In addition, when the CPU 80 does not receive any message from the DTMF detection unit 70 even after 30 seconds have elapsed, the CPU 80 determines that an abnormality other than a ring signal error, a power error, a system state error, a transmission line error, and the like occurs. The controller 100a to 100f is selected to transmit a message indicating the content determined by the selected segment controller 100a to 100f and at the same time, to transmit an appropriate control signal to the LED controller 110 and the speaker controller 120. In addition, when the speaker controller 120 receives the control signal transmitted from the CPU 80 and changes the period and frequency of the speaker according to the control signal to generate an alarm sound in the speaker, the system operator hears the alarm sound and recognizes the alarm content. In one case, it is determined that the alarm sound from the speaker no longer needs to be input, and the speaker off switch provided in the switch unit 130 is input or the volume provided in the switch unit 130 for the user to adjust the volume of the speaker. When the adjustment dial is turned, the switch unit 130 detects this and outputs a speaker off control signal or a volume control control signal to the speaker controller 120. The speaker controller 120 receives the speaker off control signal or the volume control control signal transmitted from the switch unit 130 and turns off the speaker until the next cycle of the speaker control signal or the volume of the speaker according to the received control signal. Adjust

As described above, the present invention not only displays a predetermined number of abnormal states that may frequently occur in the system by receiving an exchange status message using a DTMF signal, but also installs various types of display units in a convenient place for the user. The frequency and frequency can be changed on a case-by-case basis, allowing the operator to hear audible alarms from a distance away from the exchange, providing operator convenience in managing the system.
