In the conventional uninterruptible power supply, the commercial power is supplied to the microcomputer 56 even while the power supply to the load equipment is stopped. However, if a power failure such as a power failure occurs during this stop period, power supply to the microcomputer 56 will also stop. For this reason, all power supply to the microcomputer 56 is cut off, and the microcomputer 56 cannot perform scheduled operation.

Moreover, when the microcomputer 56 is restarted after the power supply is restored to normal, the next startup time set in the memory is initialized. Therefore, even if the microcomputer 56 is restarted after the power failure that has occurred during the stop period of the uninterruptible power supply, the microcomputer 56 cannot perform the correct scheduled operation.

The present invention has been made in view of the above problems, and even if an abnormality occurs in the commercial power supply in a state where the uninterruptible power supply is in a schedule operation and the operation thereof is stopped, the power supply abnormality occurs. It is an object of the present invention to obtain an uninterruptible power supply device that can continuously start and stop load devices based on a power supply schedule that has already been set.

Embodiment 1.

FIG. 1 is a system configuration diagram showing a power supply system to which the uninterruptible power supply according to the first embodiment of the present invention is applied.

In this power supply system, an uninterruptible power supply 3 is arranged between a commercial power supply 1 as a power supply and a computer 2 as a load device. Further, the computer 2 and the uninterruptible power supply 3 are connected by a communication line 4, and the communication line 4 can be used to send and receive setting data and commands to each other.

In the computer 2, a power management program (not shown) is operating, and the computer 2 receives a stop command from the uninterruptible power supply 3 or self-stops.
The stop process of is executed.

A power schedule program (not shown) is operating in the computer 2, and a power schedule is generated as a result of the processing of this program. Then, when this power supply schedule is generated, the computer 2 extracts the next start time from the power supply schedule by using the time in the computer 2 at that time when the stop processing of the computer 2 is executed. The next start time is transmitted to the uninterruptible power supply 3. Here, scheduled operation based on the power supply schedule means turning on / off the uninterruptible power supply at the time set by the computer.
It means the operation to turn off (ON / OFF).

In the first embodiment, the power supply schedule program is executed in the computer 2 as the load device connected to the uninterruptible power supply 3. However, this program is executed by the computer as the load device. Instead of 2, it may be executed in a computer provided separately.

FIG. 2 is a block diagram showing the circuit configuration of the uninterruptible power supply 3 in FIG.

The uninterruptible power supply device 3 includes an input terminal pair 5 to which the commercial power supply 1 is connected, a converter 6 as a charging member for converting AC power input from the input terminal pair 5 into DC power, and a converter 6. A battery 7 that is connected in parallel to the output and is charged with the DC power as a power storage member, an inverter 8 that converts the DC power into AC power with power quality equivalent to that of the commercial power source 1, and an output of the inverter 8. An output terminal pair 9 to be connected and a DC power line pair 10 connecting the output of converter 6 and the input of inverter 8 are provided.
The computer 2 as a load device is connected to the output terminal pair 9.

The uninterruptible power supply 3 further includes a timer 13 as a timepiece member and a memory 12 as a storage member, and a microcomputer 13 as a control means.
A communication interface (communication I / O) that is provided between the input terminal pair 5 and the converter 6 and communicates between the detection member 14 as an abnormality detection member that detects the power quality of the commercial power supply 1 and the computer 2. F) 15 and a microcomputer power supply circuit 16 as a power supply member for supplying electric power to the microcomputer 13.

When the commercial power supply 1 is turned on to the uninterruptible power supply 3, the microcomputer 13 resets the memory 12 and the timer 11 and initializes the inverter 8, and then performs a predetermined monitoring sequence. To execute.
In this monitoring sequence, the microcomputer 13
Determines the detection signal from the detection member 14, and the commercial power source 1
When it is determined that is abnormal, the converter 6 is stopped and the electric power stored in the battery 7 is supplied to the computer 2 via the inverter 8.

After that, if the abnormality is not determined within a predetermined period, the converter 6 is activated again. On the contrary, if the state determined to be abnormal continues even after the lapse of a predetermined period, the communication I / F 15 outputs a stop command to the computer 2. As a result, even if a momentary power failure occurs in the commercial power supply 1, stable AC power can be supplied to the computer 2 without being affected by this, and if the commercial power supply 1 continues to be abnormal for a long period of time. In response to this, the computer 2 can be safely stopped.

When the microcomputer 13 receives the next activation time from the computer 2 immediately before the communication I / F 15 is stopped, the microcomputer 13 writes this time in the memory 12. Even if the existing time is written in the memory 12, it is written by overwriting update. In addition, the microcomputer 13 receives the next start time,
The inverter 8 is stopped after a predetermined time of several minutes has passed. As a result, power supply to the computer 2 is stopped.

After that, the microcomputer 13 restarts the inverter 8 at the starting time stored in the memory 12. Also, depending on the settings, communication I / F
A start command is output from 15 to the computer 2. Thereby, the computer 2 can be started at a desired time.

The information transmitted from the computer 2 to the uninterruptible power supply 3 during the stop processing may be the period until the next startup instead of the next startup time. Also,
Information written in the memory 12 of the uninterruptible power supply 3 is also
It may be the period until the next activation instead of the time itself. These may be appropriately selected depending on the processing of the control program executed by the microcomputer 13 and the accuracy of the timer 12.

In the first embodiment, the computer 2 outputs only the next start time, and
Although the inverter 8 is stopped by the microcomputer 13 after a lapse of a predetermined time with reference to the reception of the next start time, a stop completion command is separately output from the computer 2 at the stage when the stop process is completed, and the microcomputer 8 Alternatively, the inverter 8 may be stopped based on the time when the stop completion command is received. Then, the waiting period from the reception of the stop completion command to the stop of the inverter 8 may be set appropriately.

FIG. 3 shows the microcomputer power supply circuit 16 shown in FIG.
2 is an electric circuit diagram showing the circuit configuration of FIG.

The microcomputer power supply circuit 16 includes a battery connection terminal pair 17 connected to the DC power line pair 10, a microcomputer output terminal pair 18 connected to a power supply terminal (not shown) of the microcomputer 13, and a battery connection terminal pair 17. A three-terminal regulator 19 that converts the voltage of the DC power input from the device and outputs it to the microcomputer output terminal pair 18, a power supply transistor 20 that is inserted and connected between the battery connection terminal pair 17 and the three-terminal regulator 19, and power supply A switching transistor 21 connected to the base of the control transistor 20.

Before and after the three-terminal regulator 19, capacitors 22 and 23 for stabilizing the voltage are respectively arranged, and the battery connection terminal pair 17 and the power feeding transistor 2 are provided.
Resistors 24 and 25 are inserted and connected between 0 and 0 and between the feeding transistor 20 and the switching transistor 21, respectively. Then, the three-terminal regulator 1 is controlled by controlling the switching transistor 21 to the ON state.
Electric power is input to 9, and the microcomputer 13 can be operated by the DC power supplied from the DC power line pair 10.

A resistance element 26 is connected in parallel with the base and emitter of the switching transistor 21, and
The activation sustaining signal output from the microcomputer 13 is input to the base of the switching transistor 21 via the activation continuation maintaining signal input unit 41, the resistance element 27 and the diode 28, and is also input to the input terminal pair 5. The voltage obtained by rectifying the electric power is input via the Zener diode 29. As a result, the switching transistor 21 is controlled to the ON state by controlling either the activation maintaining signal or the rectified voltage to the high level, and the microcomputer 13 can continue to operate during that time. Here, the activation maintaining signal is always output when the microcomputer 13 is activated, and is continuously output as long as the microcomputer 13 continues to operate.

A capacitor 30 is connected between the diodes 28 and 29 and the base of the switching transistor 21 in parallel between the base and the emitter, and
Another resistor element 3 is provided between the capacitor 30 and the resistor element 26.
1 is provided. Thereby, the base voltage of the switching transistor 21 can be stabilized.

Further, the circuit for rectifying the commercial power is specifically, the diode bridge 3 connected to the input terminal pair 5.
2 and a capacitor 33 connected to the diode bridge 32, and the voltage of the capacitor 33 is applied to the Zener diode 29 in the reverse direction.

In such a rectifying circuit, commercial power is full-wave rectified by the diode bridge 32, and the rectified voltage charges the capacitor 33. And capacitor 3
When the charging voltage of 3 becomes equal to or higher than the breakdown voltage of the Zener diode 29, a reverse current flows through the Zener diode 29, and the switching transistor 21 is controlled to the ON state.

Therefore, this microcomputer power supply circuit 16
When the commercial power is input in response to the commercial power supply 1 being turned on, the switching transistor 21 is controlled to be in the ON state and the microcomputer 13 is activated.

By the way, the microcomputer 13 which is activated in this way starts outputting the activation maintaining signal which becomes a high level voltage at the time of its activation, and judges that it is abnormal based on the detection signal from the detecting member 14. When the period has passed a predetermined period, the activation maintaining signal is controlled to be low level. The start-up maintaining signal is at a low level even when a power switch (not shown) of the uninterruptible power supply 3 is turned off. Further, this predetermined period may be determined based on the depth of discharge of the battery 7 or the like, but generally, it may be set within 12 hours. As a result, it is possible to prevent the discharge depth of the battery 7 from becoming too deep due to the power supply to the microcomputer 13, and it becomes impossible to supply sufficient power to the load device, or the battery 7 cannot be sufficiently supplied. It is possible to prevent the deterioration from being accelerated.

If the converter 6 can output at least the electric power larger than the electric power capable of charging the battery 7 and the electric power consumed by the microcomputer 13 together with the setting of such a period. However, preferably, a power larger than the sum of the power consumption of the microcomputer 13 and the charging power of the battery 7 is output so that the power consumed by the microcomputer 13 can be supplemented while storing the battery 7. It is better to configure it. As a result, the electricity stored in the battery 7 is not consumed during normal operation, and it is possible to prevent the life of the battery 7 from being shortened.

Next, the overall operation of the power supply system having such a configuration will be described.

The commercial power supply 1 is connected to the input terminal pair 5 of the uninterruptible power supply 3, and the computer 2 as a load device is connected to the output terminal pair 9. Also, the computer 2
And the communication I / F 15 are connected.

When the power of the uninterruptible power supply 3 is turned on in this connection state, the capacitor 33 is charged with commercial power and the switching transistor 21 is controlled to be in the on state. As a result, the DC power supplied to the DC power line pair 10 via the converter 6 or the DC power previously stored in the battery 7 is converted into the three-terminal regulator 19
Power is supplied to the microcomputer 13 via. The microcomputer 13 consumes this power and starts its operation, and performs initialization processing such as resetting the memory 12 and starting the inverter 8. In addition, the microcomputer 1
3 starts to output the activation maintaining signal.

Further, when the inverter 8 is activated, communication I
When the computer 2 is started based on the start command output from the / F15, the DC power output from the converter 6 is directly supplied to the battery 7 and the microcomputer 13, and is converted into AC by the inverter 8. It is converted and supplied to the computer 2.

After that, the uninterruptible power supply 3 is scheduled to be operated by the computer 2. When an abnormal state such as a momentary power failure occurs in the commercial power source 1 in a state where commercial power is being supplied to the computer 2 via the uninterruptible power supply 3, the microcomputer 13 based on the detection signal of the detection member 14. Judges this and stops the operation of the converter 6. This allows the battery 7
The electric power stored in the computer 2 is supplied to the microcomputer 13 and the computer 2, and the computer 2 can continue to operate normally even if the power supply is abnormal.

When it is determined that the commercial power supply 1 has returned to the normal state based on the detection signal of the detection member 14, the microcomputer 13 operates the converter 6 again. As a result, the commercial power is again supplied to the microcomputer 13
Also, the battery 7 can be charged with commercial power while being supplied with power to the computer 2.

On the contrary, when the abnormal state judged based on the detection signal of the detection member 14 continues for a predetermined time or longer, the microcomputer 13 causes the communication I / F 15 to send a stop command to the computer 2. Computer 2
Then, the stop processing is performed in response to the reception of the stop instruction. At this time, when the power schedule is generated in the computer 2, the next start time is sent as a response to the uninterruptible power supply 3. In the uninterruptible power supply 3, the communication I
/ F15 receives this next start time, and the microcomputer 13 stores this next start time in the memory 12. After the computer 2 has stopped, the uninterruptible power supply 3
Stops the operation of the inverter 8. As a result, even if the commercial power supply 1 has an abnormal state, the computer 2 connected to the uninterruptible power supply 3 can be normally terminated and then stopped, and the computer 2 It is possible to prevent the disappearance of the noise.

By the way, even after the computer 2 is stopped in this way, that is, even after the control of the scheduled operation by the computer 2 is interrupted, the microcomputer 13 operates on the power of the battery 7 or the commercial power restored thereafter. continuing. When the time determined based on the timer 11 reaches the start time stored in the memory 12, the inverter 8 is restarted and
A start command is output to the computer 2 according to the setting. As a result, the computer 2 can be activated based on the preset power supply schedule.

In addition to the start / stop control based on such a power supply schedule, when the abnormal state of the commercial power supply 1 has passed a certain period, the microcomputer 13 stops the output of the start-up maintaining signal. To do. As a result, it is possible to prevent the depth of discharge of the battery 7 from exceeding a certain level, and it is possible to maintain the function and performance of the uninterruptible power supply 3 while suppressing the deterioration of the battery 7.

As described above, in the uninterruptible power supply 3 according to the first embodiment, the uninterruptible power supply 3 is stopped due to a schedule operation or the computer 2 as a load device is stopped. Even if an abnormality occurs in the commercial power supply in this state, the microcomputer 13 continues to output the activation maintaining signal to the microcomputer power supply circuit 16 and continues to supply the power of the battery 7 to the microcomputer power supply circuit 16, and as a result, the microcomputer Since 13 continues to operate, the next activation time can be kept stored in the memory 12. Therefore, the start and stop of the load device based on the power supply schedule can be continued regardless of the power supply abnormality.

Next, the scheduled operation is performed, and at the set time, the UPS 3 is shut down,
A case where a power failure such as a power failure occurs during the shutdown will be described.

When the uninterruptible power supply 3 shuts down according to the power supply schedule by the computer 2, the microcomputer 13 causes the converter 6,
It operates to stop the inverter 8. Prior to these stop processes, the computer 2 transmits the next start time to the uninterruptible power supply 3 based on the power supply schedule and stores it in the memory 12. The uninterruptible power supply 3 is shut down by stopping the converter 6 and the inverter 8, but at this time, the power supply from the battery 7 to the microcomputer power supply circuit 16 is not interrupted. Microcomputer power supply circuit 16
Continues to be supplied with power from the commercial power supply 1 and continues to supply power to the microcomputer 13.

That is, the microcomputer power supply circuit 16 receives power from the dual power supply of the commercial power supply 1 and the battery 7. The activation maintaining signal from the microcomputer 13 continues to be input to the activation maintaining signal input unit 41 of the microcomputer power supply circuit 16.

If a power failure such as a power failure occurs while the uninterruptible power supply 3 is shut down, that is, when the microcomputer power supply circuit 16 is not supplied with power from the battery 7, the converter 6 is stopped. Therefore, the power supply from the commercial power supply 1 to the microcomputer power supply circuit 16 is also interrupted.

However, the start-up maintaining signal is input to the microcomputer power supply circuit 16, making it appear as if the commercial power supply 1 continues to be input. Therefore, the switching transistor 21 continues to be in the on state, and the power supply transistor 20 also remains in the on state. As a result, the power supply from the battery can be continued. For this reason,
The microcomputer power supply circuit 16 continues to supply power even if the commercial power supply 1 fails, and the microcomputer 13 can continue to operate without stopping.

The power supply from the battery 7 can be continued for a set predetermined period, for example, a set period within 12 hours. When the power failure is restored while the power supply from the battery 7 to the microcomputer 13 continues and the supply of the commercial power supply 1 is started, this power is supplied to the microcomputer power supply circuit 16 again. The power supply from the battery 7 to the microcomputer power supply circuit 16 and the power supply from the commercial power supply 1 to the microcomputer power supply circuit 16 may be switched by detection by the detection member 14, for example.

It should be noted that the microcomputer 13 outputs the start-up maintaining signal for the set predetermined period, and the microcomputer power supply circuit 16 continues to supply the power stored in the battery 7 to the microcomputer 13. However, if the microcomputer 13 is continuously driven by the stored power of the battery 7 for a too long time, the charging voltage of the battery 7 drops. If the battery 7 that has been discharged for a long period of time is not charged, it becomes impossible to supply the prescribed prescribed power to the load device. Further, the battery 7 discharged in a light load state (a state in which the power consumption is small), that is, the state in which only the microcomputer 13 is operated has a deeper discharge depth (the charging time for reaching the charging voltage is long even if the battery 7 is charged). That is, the battery 7 cannot be used.

For this reason, the start-up maintaining signal may stop the output from the microcomputer 13 before such a state occurs, that is, after a predetermined time, for example, 12 hours, 8 hours, 6 hours, or the like. . As a result, the discharge depth of the battery 7 can be prevented from becoming deep, and the function as a backup power source can be maintained and secured.

The above embodiment is a preferred embodiment of the present invention, but various modifications can be made without departing from the gist of the present invention. For example, in the above embodiment, only the next start time of the load device is transmitted as the time information to be transmitted to the uninterruptible power supply 3 based on the power supply schedule. The next stop time may be transmitted instead of the start time. Instead of the stop time, a period until the stop may be transmitted.

[0063]

According to the present invention, even if an abnormality occurs in the commercial power supply in a state where the uninterruptible power supply is scheduled to operate and its operation is stopped, the power supply already set regardless of the abnormality in the power supply. The start and stop of the load device based on the schedule can be continued.
