3 is a flowchart showing an abnormal state notification method of the uninterruptible power supply according to the present invention.

The abnormal state notification method according to the present invention includes the steps of: (S31) receiving an abnormal state detection signal from a sensor installed at each part of an uninterruptible power supply; A step (S32) of reading the telephone number of the manager from the telephone number storage unit (24); (S33) of operating the telephone line loop unit (29) in an ON state and connecting it to a telephone line; Generating a DTMF signal by operating the tone transmitting section 26 and transmitting the DTMF signal to a telephone line (S34); A step (S35) of judging whether the ring back tone detecting section (25) detects a ring back tone signal or a busy signal; (S36, S38) if it is determined that the busy signal is three times if the busy signal is detected, and if not, the telephone line is closed and the step S32 and subsequent steps are repeated; (S36, S37) repeating step S33 and subsequent steps after the telephone line is disconnected three times and the telephone number storage section (24) reads the next telephone number; (S39 to S41) repeating steps S40 to S41 after determining that the ring back tone is detected 10 times if the ring back tone is detected, sending the voice message and sending the voice message twice, if not twice, disconnecting the telephone line; If the voice message is transmitted twice, it is determined whether it is the last telephone number (S42). If the voice message is not the last number, the telephone line is disconnected and the next telephone number is read from the telephone number storage unit 24, (S43); And ending the program if it is the last number.

A plurality of sensors of the signal input unit 21 receive fault detection signals of respective parts of the UPS. For example, the power supply of the battery is sensed and a low voltage detection signal due to overcharging is input (step S31).

Fig. 4 shows an example in which sensors are installed at respective portions of the uninterruptible power supply according to the present invention.

And an input / output terminal (41) of a commercial power source is provided with a power / disconnection sensor (C) for detecting power loss and power loss. A bypass sensor (A) is installed on the bypass power line (42) bypassing the uninterruptible power supply unit to sense a bypass power source.

The commercial power input from the input terminal 41 of the commercial power source is converted into a direct current from the converter 43 and charged into the battery 45. [ A low-voltage detection sensor (D) is installed in the rechargeable battery (45) to sense the over-discharge state of the battery (45). The inverter (44) is also provided with a sensor (B) to detect the operating state of the inverter (44).

When an abnormal signal is detected from each sensor, the phone number storage unit 24 reads the telephone number of the manager (step S32), and operates the telephone line loop unit 29 to connect to the telephone line (step S33).

After connecting with the telephone line, the tone sending unit 26 is operated according to the read telephone number to generate a DTMF (Dual Tone Multi-Frequency) signal to call the manager's telephone (step S34). A ring tone is sent to the manager's telephone and the ring back tone is detected by the ring back tone detecting section 25. [

If the RBT signal is detected 10 times (step S39), the message storage unit 30 reads out a message corresponding to the sensor in which the abnormal signal is sensed and transmits it to the manager phone (step S40). At this time, it is also output to the speaker unit 28 and reproduced by the speaker SP by voice.

FIG. 5 shows the contents of a message stored in the message storage unit 30 according to a signal input from each sensor of the signal input unit 21.

The bypass notification mode is a state in which the inverter 44 is in a stopped state and outputs a state of being outputted to a commercial power supply. The conditions to be bypassed are such as an overload, a temperature rise, a battery voltage, an inverter low voltage abnormality, or an inverter failure.

If a power failure occurs in the bypass state, the output will be cut off and all the systems in use will be down, causing a system failure or data loss, so the wired or wireless phone will send a "UPS is bypassed" message.

The inverter failure notification mode is generated by the failure of the control board, the drive board, the semiconductor device, and the fuse constituting the inverter 44, and the message "UPS is faulty"

The power failure notification mode is a power failure state caused by the interruption of the commercial power supply and the interruption of the input switch, and the uninterruptible power supply unit supplies power to the load by receiving power from the battery (45). At this time, the message "I am using UPS due to power failure" is sent.

In the battery voltage error mode, the battery 45 is over-discharged due to excessive use of the battery 45, and the message "the battery voltage is dropping" is sent.

In the power save mode, commercial power is supplied again from the power failure state. "KEPCO is back up and UPS is in normal operation."

It is judged whether or not this message transmission is two times, and a message 2 is sent per one telephone number. A number (for example, five) of telephone numbers are stored in the telephone number storage unit 24, and a message is notified twice for each telephone number.

If it is not the last time, the telephone is disconnected and the next telephone number is read from the telephone number storage 24, and if it is not the last telephone number stored in the telephone number storage 24 in step S33 Repeat the following procedure.

On the other hand, if a busy signal is received by the manager's telephone and a busy signal is received (step S36), it is determined whether the busy signal has been received three times (step S36) (Step S32), and repeats the process of step S33 and subsequent steps. If the call is still repeated three times (step S36), the next telephone number is read and the message is delivered to another manager S37).

As described above, according to the present invention, abnormality of each part of the uninterruptible power supply can be automatically determined and analyzed to notify the abnormal state, and malfunction of the uninterruptible power supply can be prevented in advance by the automatic notification, It is possible to notify a large number of administrators, thereby enhancing the reliability of the safety check.
