The input and display unit 50 is a known data input device such as a keyboard, a switch, a button, and a known display device such as a monitor, a light emitting diode (LED), or a liquid crystal display (LCD). It plays a role of showing status and message to user. The memory 60 is for storing data designated by the user, for example, a telephone number to be called when a password or an abnormality occurs, and other various optional data. The voice generator 40 is an optional element and is used to inform the user of a message or an abnormality of the UPS unit 10 as voice. The voice generator may be in the form of pre-recording a message on a tape or the like. Preferably, the voice recorder is digitally recorded on the IC, and the required message is selected and played, or a voice synthesizer is used to synthesize a voice. It's a good idea to use something that tells you. The telephone line interface 70 is connected to the telephone line and performs various operations related to the telephone such as making, receiving, and dialing a telephone (mechanical or electronic) under the control of the controller 30. The controller 30 includes a conventional microprocessor and a ROM, and performs various control operations according to a program stored in the ROM.

2 is a schematic diagram showing a situation in which the uninterruptible power supply and various external communication devices of the present invention are connected to a telephone line network. The uninterruptible power supply of the present invention is connected to an existing telephone line network through the telephone line interface unit 70. Telephone lines are usually connected to telephone lines, but in many cases fax and modem connections are available, and they can also be connected to a wireless paging base station via an exchange. Therefore, the uninterruptible power supply of the present invention can be accessed from the outside using a telephone, a fax, a modem, a beep, and the like through a telephone line network. And a user using a mobile phone or pager, etc., can be seen that at any time, even outside the office can be contacted the abnormal occurrence from the uninterruptible power supply of the present invention or check the status of the uninterruptible power supply.

Next, the operation of the control unit 30 of the uninterruptible power supply of the present invention will be described with reference to FIGS. 3 to 7. 3 is a flowchart illustrating an operation of the control unit of the uninterruptible power supply of the present invention, FIG. 4 is a flowchart showing an operation of the control unit when a call is made to the uninterruptible power supply, and FIG. 5 is a pager mode of the uninterruptible power supply. Is a flowchart illustrating the operation of the control unit when an alarm occurs in the uninterruptible power supply when the control unit is in operation, and FIG. 6 is a flowchart illustrating an operation of the control unit when an alarm occurs in the uninterruptible power supply when the uninterruptible power supply is not in pager mode. 7 is a flowchart illustrating an operation in a programming mode of a controller.

First, referring to FIG. 3, the controller 30 continuously checks whether various events occur in normal times. If a signal indicating that a telephone ring is coming from the telephone line interface 70, the controller 30 proceeds to A in step S100. If the UPS unit 10 receives a signal indicating that an abnormality has occurred from the UPS interface 20, the flow advances from step S101 to step S103 to check whether the present device is programmed in pager mode, and is in pager mode. If it is B, otherwise it goes to C. Further, when a signal indicating that the button is pressed is input from the input and display unit 50, the control unit 30 proceeds to step D102 in step S102. In addition, the control returns to A, B, C, and D, and then returns to E to repeat the above operations indefinitely.

Next, the operation of the control unit 30 when the telephone ring is detected in step S100, that is, the operation of the control unit 30 in A will be described with reference to FIG. 4.

When a call comes in, the control section 30 first checks in step S201 whether the apparatus is set to an automatic reception mode. Auto-receive mode is preset by the user and sets whether the device will answer when a call comes in. If it is not set to the automatic reception mode, it is not necessary to answer the call and therefore immediately exits to E. Otherwise, go to step S202 to answer the call. The voice message is then sent to the caller in step S203. The contents of the voice message may include an ID number of the uninterruptible power supply, an installation place, and a guide of what actions can be taken by the caller, but the present invention is not limited thereto. no. That is, the caller may enter the code without a voice message.

After the voice message transmission is finished or even during voice message transmission, it is checked whether the caller enters the code in step S204. This code can be arbitrarily determined, for example, 1 is to check the measured value of the uninterruptible power supply, 2 is to confirm the current alarm, 3 is to display the alarm details, 4 is to control the uninterruptible power supply, and 5 is to set the uninterruptible power supply. , 6 can be defined as an exit code. When the caller presses these codes, it is checked in step S205 whether this code is an end code, and if not, the process goes to step S206 to output a voice message corresponding to each code. That is, when code 1 is pressed, various measurement values of the uninterruptible power supply, for example, input voltage, output voltage, battery voltage, and internal temperature, are spoken by voice, and when code 2 is pressed, the current alarm is voiced. . When the voice message transmission is completed for each code in this way, it is again checked in step S204 whether the caller enters another code. At this time, if the caller does not enter the code within 30 seconds, the process goes to step S207 to hang up. Also, even if the caller dials the end code, the process goes to step S207 to hang up the call. Goes.

Next, the operation of the control unit 30 when the alarm is detected in step S100 when the apparatus is set to the pager mode, that is, the operation of the control unit 30 in B will be described with reference to FIG. 5.

First, the control unit 30 finds out by reading an alarm code which alarm has occurred in step S301. Next, in step S302, the controller 30 reads the pager number from the memory 60 and dials the number in step S303.

After making a call, it is checked in step S304 whether a telephone connection is established. As a method of checking whether the telephone connection is established, there is a method of determining a busy tone or an error sound, but the present invention is not limited thereto. If the dial-up is not established within a predetermined time in step S304, in step S309, the telephone hangs up and tries again. For example, if more than three attempts have been made (YES in step S310), the next pager number is read (step S311). ) Try again with this new number. This operation is repeated until the telephone connection is completed.

When the telephone connection is completed, it is checked in step S305 whether to use the voicemail function. If it is set to use the voicemail function, in step S306, the code and the alarm code of the apparatus are transmitted as voice from the voice generator 40 to record the voicemail of the pager. If the voicemail function is not used, the code and alarm code of the device are sent to the DTMF using the DTMF generator in step S307 to leave the code and alarm code of the device in the beeper. Then, the telephone hangs up in step S308 and returns to the main loop of FIG. 3 again.

Next, the operation of the control unit 30 when the alarm is detected in step S100 when the apparatus is not set in the pager mode, that is, the operation of the control unit 30 in C will be described with reference to FIG. 6.

First, the controller 30 finds out by reading the alarm code which alarm has occurred in step S401. Next, in step S402, the controller 30 reads the telephone number from the memory 60 and dials the number in step S403.

After making a call, it is checked in step S404 whether a telephone connection is established. If the dial-up is not established within this time in this step, hang up and try again in step S407. For example, if you have tried more than 3 times ("YES" in step S408), read the next phone number (step S408). ) Try again with this new number. This operation is repeated until the telephone connection is completed.

When the telephone connection is completed, an alert is sent in step S405. As a method of transmitting an alarm, when the other party is a person who uses only a normal telephone, the voice generator 40 converts the alarm code and the code of the apparatus into voice and transmits the voice. The telephone number is transmitted through a modem. When connected to a computer, a method in which a modem in the telephone line interface 70 converts an alarm code and a code of the apparatus into data and sends the data. When the telephone number is connected to a fax, the telephone line interface 70 There may be a method of using a fax modem to convert an alarm code, a code of the device, and the like into fax data. Also, in step S405, only the fact that an alarm has occurred can be notified, and the device manager can call the device to find out the details as described in FIG. 4.

When the alarm transmission is completed in step S405 as described above, the control unit 30 hangs up in step S406 and returns to the main loop of FIG. 3 again.

Next, the operation of the controller 30 when the programming button is pressed in step S100, that is, the operation of the controller 30 in D will be described with reference to FIG. 7.

First, when the user presses a password in step S501, the control unit 30 reads it. In step S502, the controller 30 checks whether the password input by the user and the password stored in the memory 60 match. If the password does not match, the controller 30 goes to step S512 to generate an error sound, and then, in FIG. Break out of the loop.

If the passwords match in step S502, the process goes to step S503 to select a program target. In this description, a password, a pager number, a phone number, and an option of a device are programmed as an example. In this description, it is assumed that the input and display unit 50 has a "programming button", a "save" button, and a dial button. .

If the user selects the dial "1" corresponding to "change password" in step S503 and goes to step S504, the user enters a new password and presses the "save" button. Store in memory 60 and exit to main loop of FIG. If the user wants to change the pager number in step S503 and selects the dial "2" corresponding to "pager number input", the process goes to step S506. When the user enters a new pager number and presses the "save" button, the control unit 30 proceeds to step S507. Saves the newly entered pager number in memory 60 and exits to the main loop of FIG. If the user wants to change the phone number in step S503 and selects the dial "3" corresponding to "phone number input", the process goes to step S508. When the user enters a new pager number and presses the "save" button, the control unit 30 performs step S509. Stores the phone number in memory 60 and exits to the main loop of FIG. If the user selects the dial "4" corresponding to "option designation" in step S503 and goes to step S510, the user changes the option and presses the "save" button. The option is stored in memory 60 and exits to the main loop of FIG.

The process of Figure 7 can also be done by the user making a call. That is, in the process of FIG. 4, a code corresponding to "programming" may be provided among the codes selected in step S204, and the code may be moved to D when the code is pressed. In this case, of course, it is necessary to go to step S207 instead of going to E when the process of FIG. 7 is exited. This allows a user to enter a new phone number when the user changes the option of the apparatus from the outside or moves to a location of another phone number.

As mentioned above, although this invention was demonstrated to the specific embodiment as an example, this invention is not limited to this. For example, in the above description, the voice generator 40 is included to transmit the voice message. However, the voice generator cannot transmit the voice message even without the voice generator.

In addition, although the telephone automatic reception and the automatic alarm transmission are all described as being performed by one apparatus, only one of the functions may be performed. That is, it removes the function of automatically sending an alarm and only the function of the administrator making a call and confirms it, or vice versa, the function of the administrator making a call and confirms the status, and only when an alarm occurs, the phone is transferred to the designated place. You may employ | adopt only the function to call. In addition, the present invention can be used in a similar device, that is, a voltage regulator, etc. in addition to the uninterruptible power supply, the configuration is the same.

The device manager can be automatically contacted in the event of an external device inspection, an abnormality in the device, or a possibility of occurrence, thereby reducing the maintenance cost of the device and reducing the damage caused by an unexpected device failure.
