Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1 shows a schematic configuration of the first embodiment. In the figure, 1 is a data setting unit, and this data setting unit 1 is connected to a control unit 3 via a data input unit 2.

Here, the data setting unit 1 stores time data such as the operation start time and the operation stop time as information on when the uninterruptible power supply main body 6 to be described later is put into operation and when to be stopped. It is for setting. In this case, the data setting unit 1 can set the operation and stop information for one day, assuming that the time at which the operation of the uninterruptible power supply main body 6 should be stopped every day is predetermined. The data input unit 2 is composed of a buffer or the like, and is configured to supply the data set by the data setting unit 1 to the control unit 3.

The control section 3 controls the entire apparatus and gives a control command to the memory 4, the set time determination section 5 and the uninterruptible power supply main body 6. Memory 4
Is a RAM or the like, and stores various time data such as the operation start time and operation stop time set by the data setting unit 1.

A calendar timer 7 is connected to the set time determination unit 5. The calendar timer 7 clocks the current time of year / month / day / hour, and outputs the clocked information to the set time comparison unit 5. Further, the set time determination unit 5 compares and determines the time information of the calendar timer 7 and the time data stored in the memory 4. When the time information matches the time data, an output corresponding to the time data at this time is output. It is given to the control unit 3.

The uninterruptible power supply main unit 6 is for connecting a load facility 8 such as a computer, and is composed of an energy storage device such as a storage battery. When the commercial AC power supply fails, the energy is replaced in place of the commercial AC power supply. Power is supplied to the load equipment 8 by a storage device. Then, the uninterruptible power supply main body 6 is controlled to start and stop the operation according to a control command from the control unit 3.

The control unit 3 except the uninterruptible power supply main unit 6 and each circuit controlled by the control unit 3 are backed up by an energy storage device so that the function does not stop even when the uninterruptible power supply main unit 6 is at rest. Of course it is done.

Next, the operation of the embodiment configured as described above will be described. In this case, when the automatic operation of the uninterruptible power supply main body 6 is instructed, the flowchart shown in FIG. 2 is executed.

First, in step 201, the data setting unit 1
Input the time data with. In this case, each time data of the start-up time and the stop-down time of the operation is set as information on when the uninterruptible power supply main body 6 should be put into operation and when to be stopped.

Next, in step 202, the data setting unit 1
Each time data of the start-up time and the end-time of the operation set in 1 is sent from the data input unit 2 to the control unit 3 and stored in the memory 4.

From this state, first in step 203,
The set time determination unit 5 compares the time information of the calendar timer 7 with the time data stored in the memory 4 to determine whether the current time matches the operation start time. Then, if NO is determined here, the next step 204
Then, the set time comparison unit 5 compares the time information of the calendar timer 7 with the time data stored in the memory 4, and determines whether the current time matches the operation shutdown time. Then, if it is also determined to be NO here, the process returns to step 203, and the same operations in steps 203 and 204 are repeated. In this case, the uninterruptible power supply main body 6 maintains the standby state in which the operation is stopped.

After that, when the time counting for the year, month, day and hour is advanced by the calendar timer 7 and the present time coincides with the operation start-up time in the time data of the memory 4, YES is determined in step 203.

Then, the set time judgment unit 5 sends an output corresponding to the start-up time of the operation to the control unit 3, and step 2
At 05, the control unit 3 gives a control command to the uninterruptible power supply main body 6 to start the operation.

On the other hand, when the time counting for the year / month / day / hour is further advanced by the calendar timer 7 and the current time coincides with the operation stop time in the time data of the memory 4, YES is determined in step 204.

Then, the set time determination unit 5 sends an output corresponding to the operation start time to the control unit 3, and step 2
At 06, the control unit 3 gives a control command to the uninterruptible power supply main body 6 to stop the operation.

When the operation of the uninterruptible power supply main body 6 is stopped, the operation is stopped after determining whether the output current to the load equipment 8 is below a specified value. After that, the operations of Step 203 to Step 206 are repeated, and the start-up and the stop of the operation of the uninterruptible power supply main body 6 are controlled.

Therefore, according to such a first embodiment,
Based on the start-up time and the end-time of the operation of the uninterruptible power supply unit 6 set in advance by the data setting unit 1, the set time determination unit 5 compares and monitors the time information of the calendar timer 7, and the current time is the operation start time. When the rising time coincides with the operation start-up of the uninterruptible power supply main body 6, and when the current time coincides with the operation stop time, the uninterruptible power supply main body 6 starts and stops the operation. So
The operation state of the uninterruptible power supply main body 6 can be automatically controlled, and compared with the conventional method of starting and stopping the operation of the uninterruptible power supply, the manpower required for these operations is reduced. In addition to being able to omit it, it is possible to reliably prevent inconveniences such as forgetting to turn on the operation switch of the uninterruptible power supply, and to realize stable operation of the load facility.

(Second Embodiment) In the first embodiment, the start and stop of the operation of the electric power source device main body 6 is controlled by the time data set in the data setting section 1. According to the command, it is possible to control the start-up and the stop of the operation of the electric power source device body 6.

FIG. 3 shows a schematic structure of the second embodiment, and the same parts as those in FIG. 1 are designated by the same reference numerals. In this case, the data input / output unit 9 is connected to the data input unit 2, and a computer system (not shown) through the data input / output unit 9 sets up the operation of the uninterruptible power supply main unit 6 as the operation reservation data for the instruction to start and stop the operation. Data such as year / month / day time, day of the week pattern, and special operation pattern are input.

In this case, the date / time data is data for instructing the operation / stop of the uninterruptible power supply main body 6 on a year / month / day basis, and the day-of-the-week pattern data is the operation permission of the uninterruptible power supply main body 6. And the special operation pattern data for instructing the operation on a day of week basis are data for instructing the operation permission of the uninterruptible power supply main body 6 only under special circumstances.

Others are the same as those in FIG. 1, and the description thereof is omitted here. In this case, the data input / output unit 9
Through the computer system (not shown), data such as the date and time of the day, the day of the week pattern, and the special operation pattern are input as the operation reservation data for the command to start and stop the operation of the uninterruptible power supply main body 6.

Then, these reservation data are sent from the data input unit 2 to the control unit 3 and stored in the memory 4. Then, in this state, in the same manner as described above, the set time determination unit 5 compares the timekeeping information of the calendar timer 7 with the reservation data stored in the memory 4.

In this case, the set time judgment unit 5 judges that
If the timekeeping information of the calendar timer 7 coincides with the start-up time of the operation of the reservation data of the memory 4, the control unit 3 gives a control command to the main unit 6 of the uninterruptible power supply to start the operation. If it coincides with the operation stop time at the date, the control unit 3 gives a control command to the uninterruptible power supply main body 6 to stop the operation.

In addition, the operation of the uninterruptible power supply main body 6 is instructed on a day-by-day basis by matching the timekeeping information of the calendar timer 7 with the day-of-the-week pattern data of the reservation data in the memory 4 in the set time determination unit 5, and similarly By matching the timing information of the calendar timer 7 with the special operation pattern data of the memory 4, the operation of the uninterruptible power supply main body 6 can be instructed only under special circumstances.

Therefore, according to such a second embodiment,
The operation state of the uninterruptible power supply main body 6 can be automatically controlled also by various kinds of operation reservation data such as date / time, day of the week pattern, and special operation pattern from an external computer system. In addition to the effects described in the embodiment, more detailed automatic operation can be realized for the uninterruptible power supply main body 6.

(Third Embodiment) FIG. 4 shows a schematic configuration of the third embodiment. The same parts as those in FIG. 2 are designated by the same reference numerals.

In this case, a current detecting section 10 for detecting the output current from the uninterruptible power supply main body 6 is provided, and in addition to the operation reservation data from the computer system (not shown) through the data input / output section 9, the uninterruptible power supply main body 6 is provided. If the output current to the load equipment 8 is not less than or equal to the predetermined value even after receiving the operation stop command for the, the operation stop of the uninterruptible power supply main body 6 is not permitted.

Others are the same as those in FIG. 2, and the description thereof is omitted here. Even in this case, the data input / output unit 9 is used as the operation reservation data for the start-up / stop operation of the uninterruptible power supply main body 6 from the computer system (not shown) as the date / time of day / weekday pattern.
Enter data such as special operation patterns.

Then, these reservation data are sent from the data input unit 2 to the control unit 3 and stored in the memory 4. Then, in the same manner as described above, the set time determination unit 5 compares the timekeeping information of the calendar timer 7 with the reservation data stored in the memory 4.

Here, when the operation stop command to the uninterruptible power supply main body 6 is received from the computer system,
This command is given from the control unit 3 to the set time determination unit 5,
The set time determination unit 5 determines the fall of the operation, and the control unit 3 outputs an operation stop command to the uninterruptible power supply main body 6.

However, at this time point, the detection output of the current detection unit 10 is checked, and if the output current to the load equipment 8 is not less than a predetermined value, the operation stop of the uninterruptible power supply main body 6 is not permitted, and then the output is output. When the current falls below a predetermined value, the operation will be stopped.

On the other hand, if the set time determination unit 5 judges that the time information of the calendar timer 7 coincides with the operation stop time of the reservation data in the memory 4, the control unit 3 causes the uninterruptible power supply unit 6 to operate. A shutdown command is given,
Also at this time, the detection output of the current detection unit 10 is checked. If the output current to the load facility 8 is not less than or equal to the predetermined value, the operation stop of the uninterruptible power supply main body 6 is not permitted, and thereafter, when the output current becomes less than or equal to the predetermined value,
The operation will be stopped.

Therefore, according to such a third embodiment,
Even when the operation stop command is given to the uninterruptible power supply main body 6, the operation stop of the uninterruptible power supply main body 6 is not permitted unless the output current to the load equipment 8 is less than or equal to a predetermined value. Therefore, it is possible to reliably prevent a situation in which the operation of the uninterruptible power supply main body 6 is inadvertently stopped while the load equipment 8 is being supplied with power from the uninterruptible power supply main body 6 due to a power failure or the like.

(Fourth Embodiment) By the way, the current time of the calendar timer 7 described above is measured based on the reference clock in the uninterruptible power supply main body 6, but the time measurement by the calendar timer 7 is as follows. The time is not always the same as the time of the internal reference clock of the external computer system as the load facility 8.

Therefore, in FIG. 4 described in the third embodiment, a command for updating the contents of the calendar timer 7 is given from the computer system which is the load facility 8 through the data input / output unit 9 at regular intervals, and based on this command. The time of the current time of the calendar timer 7 is updated based on the timekeeping of the timekeeping means built in the computer system of the load facility 8.

Therefore, according to such a fourth embodiment,
Timekeeping of current time with calendar timer 7 and load equipment 8
It is possible to eliminate the time difference from the current time measurement in
It is possible to prevent a situation in which the operation of the uninterruptible power supply main body 6 is stopped even though the load equipment 8 is still operating, and it is possible to perform accurate operation. The present invention is not limited to the above-mentioned embodiments, and can be implemented by appropriately modifying it without departing from the scope of the invention.
