BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an uninterruptible power supply system having an uninterruptible power supply provided between a power supply and a load device, a setting program, and a computer-readable recording medium storing the setting program. In particular, the present invention relates to an invention for automatically generating various setting data for an uninterruptible power supply, thereby improving a service for each user.

[0002]

2. Description of the Related Art FIG. 4 is a system configuration diagram showing an example of a conventional uninterruptible power supply system.

A conventional uninterruptible power supply system includes a commercial AC power supply 50 as a power supply, a load device 51, and an uninterruptible power supply 52 disposed on a power supply path therebetween.
And.

The uninterruptible power supply 52 includes a commercial power supply path from an input terminal 53 to an output terminal 56 via a bypass wiring 54 and a two-input switch 55, and a DC / AC inverter 58 and a two-input switch 55 from a battery 57.
The microcomputer 59 monitors an input voltage or the like and outputs a control signal to the two-input switch 55,
In the event of a power failure, control is performed to switch from the commercial power supply path to the storage power supply path. The AC / DC converter 60 is provided to charge the battery 57 with the commercial AC power supply 50.

In the uninterruptible power supply 52, the microcomputer 59 normally outputs a control signal to the two-input switch 55 so as to select a commercial power supply path, and transfers the power of the commercial AC power supply 50 to the load equipment 51. Supply. If an abnormality occurs in the commercial AC power supply 50 or the like,
The microcomputer 59 detects this abnormality based on the input voltage or the like and outputs a control signal to the two-input switch 55 for switching to the storage power supply path.

By installing the uninterruptible power supply 52 in this way, stable power can be supplied to the load equipment 51.

[0007]

However, as shown in FIG. 4, the uninterruptible power supply 52 requires essential circuits such as a DC / AC inverter 58 and a microcomputer 59 to realize its function. Provided, and of course, those circuits constantly consume power.

[0008] When a power plant in a factory is used as a power source, the voltage and frequency of the AC power are liable to fluctuate due to an increase or decrease in the number of load devices 51, unlike commercial AC power provided by a power company. In particular, the nighttime power supplied from the power plant in the factory designed on the assumption that the load is operating in the predetermined state, as shown in FIG. As a result, the voltage or the like may rise above the standard of a general commercial power supply.

When such an abnormally high voltage state occurs, the uninterruptible power supply 52 supplied based on the standard of a general commercial AC power supply judges that the power supply is abnormal, The supplied power is switched to the stored power of the battery 57.

In FIG. 5, a hatched portion indicates an allowable range of the input voltage, and a solid line waveform indicates an input voltage waveform corresponding to a stop of operation of a factory. Here, the input voltage has an upper limit level abnormality of the allowable range of the input voltage at night, and during this period, the uninterruptible power supply 52
Means that the stored power is supplied to the load device 51.

Such useless switching to the stored power when the power supply is in a normal state is difficult to grasp. For example, repeated switching to the stored power every night causes the battery 57 to deteriorate earlier than expected, and It is often recognized for the first time that the uninterruptible power supply 52 does not operate as specified at the time of a power failure. In this case, even if the uninterruptible power supply 52 is introduced, sufficient functions cannot be guaranteed when necessary.

For this reason, it is conceivable to allow the user to change the setting of the detection voltage range for switching to the storage power of the uninterruptible power supply 52 as necessary. However, if the setting is changed in this way, the uninterruptible power supply 5
2 may not function properly.

Therefore, even if a setting program for changing the setting of the uninterruptible power supply 52 from a personal computer is provided to each user, for each user who does not have sufficient knowledge and experience, the setting program is set. Can not be changed properly, at most Figure 6
Is a level at which once-a-day operation / stop switching can be set. Here, the uninterruptible power supply 52 is set to operate from 8:00 am to 10:00 pm.

According to the present invention, there is provided an uninterruptible power supply system which can reduce power consumption and the like without deteriorating the reliability of the uninterruptible power supply in such an uninterruptible power supply. It is another object of the present invention to obtain a setting program and a computer-readable recording medium recording the setting program.

[0015]

In order to solve the above-mentioned problems, an uninterruptible power supply system according to the present invention is connected between a power supply and a load device. An uninterruptible power supply for supplying power from the member to the load device, a storage unit for storing power input to or output from the uninterruptible power supply together with time information, and an accumulator stored in the accumulator. Analyzing means for analyzing data based on a predetermined period and generating various setting data used for the operation of the uninterruptible power supply, the uninterruptible power supply based on the setting data. It works.

If this configuration is adopted, the analyzing means analyzes the input power or the output power caused by the power and load accumulated by the accumulating means on the basis of a predetermined period, and further analyzes the uninterruptible power supply. It is possible to generate various kinds of setting data used for the operation. Moreover, since the setting data generated by the analyzing means is created by a technician who understands the characteristics of the uninterruptible power supply or its related persons, technical information and knowledge about the uninterruptible power supply can be obtained. The quality of the power supply can be remarkably maintained as compared with the case where each user who does not have the setting directly. Therefore, it is possible to reduce power consumption without deteriorating the reliability of the uninterruptible power supply.

In the uninterruptible power supply system according to the present invention, the uninterruptible power supply device includes a first power supply path for directly supplying at least the power of the power supply to the load device, and the power storage member being connected to the power of the power supply. And charging means for charging
The analysis means is based on the analysis of the accumulated data,
Setting data is generated for each time zone, which selects whether to supply power via the charging means to the load device or supply power through the first power supply path.

With this configuration, in the uninterruptible power supply, the path used when supplying the electric power from the power storage member to the load device, and the path used when the charging means stores the power using the power of the power supply. And selecting one of a power supply path (hereinafter, referred to as a second power supply path) for supplying power from the power supply to the load device and the first power supply path. In addition, the power supply to the load device can be supplied.

When the first power supply path is compared with the second power supply path, the first power supply path does not include a charging means or the like on the path. There is a merit that the power supply power can be supplied to the load device more efficiently (without loss), and conversely, the second power supply path can be switched to the power supply from the power storage member by stopping the charging means. Therefore, it is possible to switch from the power supply power to the storage power in a shorter time than the first power supply path, and there is an advantage that an instantaneous power failure does not occur.

Therefore, based on the analysis of the stored data, the analysis means generates setting data in which one of the first power supply path and the second power supply path is selected for each time zone, By operating the uninterruptible power supply based on this, for example, in the use time period of the load device, the load device is in a standby state or the like while using the second power supply path to prevent an instantaneous power failure. In the time zone, power consumption can be reduced by using the first power supply path, and power consumption can be reduced without impairing the reliability of the uninterruptible power supply.

In the uninterruptible power supply system according to the present invention, the analyzing means sets a detection value for detecting an abnormal state of the power supply for each time zone based on an analysis of the stored data.

With this configuration, the analysis means sets the detection value for detecting the abnormal state of the power supply for each time zone based on the analysis of the stored data. Even if the voltage fluctuates as normal, the power supply voltage abnormality can be determined based on the detected value corresponding thereto.

Therefore, even if the power supply fluctuates normally in each time zone, the reliability of the uninterruptible power supply can be maintained by changing the detection value accordingly.

A setting program according to the present invention is connected to an uninterruptible power supply connected between a power supply and a load device and supplying power from a power storage member provided therein to the load device when the power supply is abnormal. A setting program for generating setting data, storing power input to or output from the uninterruptible power supply as log data in a data storage unit together with time information;
Analyzing the log data in the data storage unit on the basis of a predetermined period, and generating setting data used for the operation of the uninterruptible power supply.

The device in which the setting program is installed generates various setting data based on log data of input power and output power of the uninterruptible power supply. Moreover, since the setting data is generated based on the setting program created by a technician who understands the characteristics of the uninterruptible power supply or a person related thereto, the technical data related to the uninterruptible power supply is The quality of the power supply can be remarkably maintained as compared with the case where each user having no information or knowledge directly sets. Therefore, by using the setting data, it is possible to reduce the power consumption without impairing the reliability as the uninterruptible power supply.

The computer-readable recording medium of the present invention is connected between a power supply and a load device, and supplies an electric power from an internal power storage member to the load device when the power supply is abnormal. A computer-readable recording medium storing a setting program for generating setting data to be set for a power supply device, wherein data relating to input power or output power transmitted from the uninterruptible power supply is stored together with time information. Storing the log data in the data storage unit, and analyzing the log data in the data storage unit based on a predetermined period to generate setting data used for the operation of the uninterruptible power supply, and storing the setting data in the data storage unit Causing the setting data to be read from the data storage unit and transmitting the setting data to the uninterruptible power supply device; It is as it has.

The computer in which the setting program is installed generates various setting data based on log data of input power and output power of the uninterruptible power supply. Moreover, since the setting data is generated based on the setting program created by a technician who understands the characteristics of the uninterruptible power supply or a person related thereto, the technical data related to the uninterruptible power supply is The quality of the power supply can be remarkably maintained as compared with the case where each user having no information or knowledge directly sets. Therefore,
By using this setting data, it is possible to reduce the power consumption without impairing the reliability of the uninterruptible power supply.

Further, since the setting program is stored in a computer-readable recording medium, it can be distributed to each user together with the uninterruptible power supply, and can be executed on a computer separate from the uninterruptible power supply. Therefore, a better service can be provided at a lower cost than in a case where this is incorporated in the uninterruptible power supply itself.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An uninterruptible power supply system according to an embodiment of the present invention, a setting program and a computer-readable recording medium storing the setting program will be described with reference to the drawings. Note that the setting program and a computer-readable recording medium on which the setting program is recorded will be described assuming that those programs are already installed in the computer.

FIG. 1 is a system configuration diagram showing an example of an uninterruptible power supply system according to Embodiment 1 of the present invention.

This uninterruptible power supply system includes a computer 1 as a load device, an AC commercial power supply 2 as a power supply, and an uninterruptible power supply 3 connected between the commercial AC power supply 2 and the computer 1. Prepare.

The uninterruptible power supply 3 comprises an input terminal 4 to which the commercial AC power supply 2 is connected, an output terminal 5 to which the computer 1 is connected, a relay type switch, and the like. A two-input switch 7, a bypass wiring (first power supply path) 9 connecting one switching contact 8 of the two-input switch 7 to the input terminal 4, and a second switching contact 10 of the two-input switch 7. The state of the connected power supply circuit 11 during power failure and the state of the commercial AC power supply 2 are monitored, and the state of the commercial AC power supply 2 and the like are determined using the setting data stored in the data storage unit 12. 7 and a microcomputer 13 for controlling the operation of the power supply circuit 11 during power failure. Note that a cut-off switch (not shown) may be provided between the two-input switch 7 and the output terminal 5 to completely stop the power supply to the computer 1.

The power supply circuit 11 at the time of a power failure includes a power storage member 14 composed of a battery or a capacitor, and a DC / AC for converting the DC power stored in the power storage member 14 into AC power having the same waveform as that of the commercial AC power supply 2. Inverter 15

The path to the C inverter 15 corresponds to a second power supply path.

In the uninterruptible power supply 3 having such a hardware configuration, the microcomputer 13 selects the bypass wiring 9 at the two-input switch 7, thereby supplying power directly from the commercial AC power supply 2 to the load device 1. Operation in the bypass operation mode and the DC in the two-input switch 7
/ AC inverter 15 is selected, and the on / off switch 18 is set to an on (connected) state. An online operation mode, and the two-input switch 7 selects the DC / AC inverter 15 and sets the on / off switch 18
And a high-efficiency operation mode in which is set to an off (that is, disconnected) state.

Comparing these operation modes, the on-line operation mode allows the earliest switching to the power supply from the power storage member 14 upon detection of a power failure of the commercial AC power supply 2, followed by the high-efficiency operation mode and the last operation mode. Then the bypass mode is set. Conversely, the power consumption of the uninterruptible power supply 3 can be minimized in the bypass operation mode, followed by the high efficiency operation mode, and finally the online operation mode. Therefore, depending on the type of load device, by switching these transmission modes as needed, it is possible to achieve a high level of both reliability and economy (suppression of power consumption).

The computer 1 as a load device includes an interface section (I / F section) 19 connected to a port (not shown) of the microcomputer 13, a control body 21 having a control section 20, a program storage section 22, A storage device 24 having a storage unit 23 and a power supply unit 25 for supplying predetermined power to these devices are provided. The output terminal 5 is connected to the power supply unit 25.

The control unit 20 executes various programs stored in the program storage unit 22 to control data transmission / reception processing with the microcomputer 13 by the I / F unit 19 and the like.

The program storage unit 22 stores a transfer program for an uninterruptible power supply, including a log storage program 26, a log analysis program 27, a transfer program 28, and the like.
Other programs that are executed by the control unit 20 are stored. The data storage unit 23 stores log data 29, setting data 30, and various other data that is used when the control unit 20 executes each program. The transfer program for the uninterruptible power supply is generally provided to each user in a state stored in a computer-readable storage medium (not shown), and the user installs the program on each computer 1. By doing so, it is stored in the program storage unit 22.

The log data 29 is data in which various data appropriately transmitted from the microcomputer 13 are stored for each time.

The setting data 30 is data for storing the data in the data storage unit 12 and operating the microcomputer 13 using the data.

The log storage program 26 is executed by the control unit 20 based on a data transmission request from the microcomputer 13 or a startup request from a timer (not shown). Then, this log storage program 2
The control unit (storage unit) 20 that executes the process 6 performs data communication with the microcomputer 13 and performs a process of additionally registering various data collected by the microcomputer 13 at that time as log data 29 together with time information. Do.

The log analysis program 27 is repeatedly executed by the control unit 20 based on a start request from a timer or the like (not shown). Then, the control unit (analyzing means) 20 that executes the log analysis program 27 analyzes the log data 29 so that the microcomputer 13 can obtain the optimal operation control, and stores the analysis results as the setting data 30. It is stored in the unit 23.

The transfer program 28 is executed by the control unit 20 based on inter-program communication from the log analysis program 27 or subsequent timer interruption. The control unit (transfer unit) 20 that executes the transfer program 28 performs data communication with the microcomputer 13 and stores the setting data 30 in the data storage unit 23.
A process of storing various data stored in the data storage unit 12 of the microcomputer 13 is performed.

Next, the operation will be described.

The commercial AC power supply 2 is connected to the input terminal 4 of the uninterruptible power device 3, and the computer 1 as a load device is connected to the output terminal 5. In the initial state when the power is turned on, the uninterruptible power device 3 is normally set to the online operation mode so that the maximum performance is exhibited during a power failure.

Thus, the AC power supplied from the commercial AC power supply 2 is supplied to the input terminal 4, the AC / DC converter 16, the online wiring 17, the DC / AC inverter 1
The power is supplied to the power supply unit 25 of the computer 1 via the five-input switch 7 and the output terminal 5. Then, the control body 21 and the storage device 24 start operating by the power supplied from the power supply unit 25. AC / D
The DC output output from C converter 16 is supplied to power storage member 14 via on / off switch 18, and power storage member 14 is charged.

In this state, the microcomputer 13 monitors the voltage and frequency of the AC power input to the input terminal 4, and monitors the voltage and frequency of the AC power supply 2 according to the standard of the commercial AC power supply 2 (for example, a voltage such as "100 v ±10%"). A process for detecting an abnormality in the power quality, such as whether the abnormality satisfies the abnormality detection range) or whether the load is overloaded, is performed at a very short cycle. Note that data such as a voltage abnormality detection range is stored as setting data 30 in the data storage unit.

When a power failure occurs, for example, in which the input voltage becomes lower than the voltage abnormality detection lower limit level (for example, “100 v−10%”), the microcomputer 13 detects this and causes the two-input switch 7 to operate. The switching from one switching contact 8 to the other switching contact 10 is performed.
As a result, the power stored in power storage member 14 is converted to DC / A
The stored power converted into AC power by the C inverter 15 is
The computer 1 is supplied to the computer 1 via the output terminal 5 and can continue to operate normally based on the stored power, even though the commercial AC power supply 2 is abnormal.

After that, when the input voltage is stabilized at a voltage higher than the voltage abnormality detection lower limit level, the microcomputer 13 detects this and switches the two-input switch 7 from the other switching contact 10 to one switching contact 8. Perform return processing. Thus, the computer operates with the AC power from the commercial AC power supply 2 and the power storage member 14 is charged.

The monitoring processing of the input power and the like and the switching processing of the power supply source at the time of a power failure are performed by the microcomputer 1.
3 is performed by the uninterruptible power supply 3 under the control of the log storage program 26 based on a data transmission request from the microcomputer 13 or a start request from a timer (not shown).
Is executed, and various data collected by the microcomputer 13 are stored in the data storage unit 23 as log data 29 together with the time information.

Thus, the log data 29 obtained by sampling the input voltage, the input frequency, the output voltage, the output frequency, and the like at predetermined time intervals is accumulated in the data storage unit 23.

The control unit 20 repeatedly executes the log analysis program 27 based on a start request from a timer or the like. Then, the control unit 20 that executes the log analysis program 27 analyzes the log data so as to obtain the optimum uninterruptible power supply processing according to the user, and uses the analysis result as the setting data 30 in the data storage unit 23. To memorize.

Specifically, first, in the present embodiment, the microcomputer 13 is made to acquire information about the voltage and frequency of the AC power input to the input terminal 4 and information about the voltage and frequency of the output terminal 5. The control unit 20 that executes the log analysis program 27 determines the importance of the load input by the user in advance, that is, the period such as one day or one week, depending on how much instantaneous power failure is allowed. The log is analyzed in units of, and operation schedule data for optimizing the operation mode in units of, for example, one hour is generated based on the log. In this analysis, other environmental information such as the environmental temperature may be appropriately considered.

For example, if the setting is such that power failure is not allowed at all, operation schedule data for operating in the online operation mode is always generated. That is, the setting is not to switch to another mode.

Conversely, as in the case where an instantaneous power failure is allowed and the computer 1 as a load device is used only in the daytime, the power consumption is constant in the nighttime period based on the log data of the power consumption. If it can be determined that power consumption does not occur, set the online operation mode or high-efficiency operation mode during the daytime when power consumption occurs, and set it during the nighttime when power consumption does not occur. Set the bypass operation mode or stop. In FIG. 2, the online operation mode is set from 8:00 am to 10:00 pm, and the stop is set at other times.

Further, a period during which an instantaneous power failure is allowed and the power consumption of the load device (computer 1) is low and stable, such as during lunch, is repeated in the same time period based on the power consumption log data. If it can be determined that this has occurred, the high efficiency operation mode is set in that time zone. In FIG. 2, the high efficiency operation mode is set from 12:00 am to 1:00 pm.

With these settings, the power consumption of the uninterruptible power supply 3 can be changed according to the use status of the user's load equipment (computer 1).
High reliability and economy.

In this embodiment, the microcomputer 13 also obtains information on the voltage and frequency of the AC power input to the input terminal 4 and information on the voltage and frequency of the output terminal 5 and performs log analysis. Program 27
The control unit 20 executes the log data 29 in units of, for example, one day or one week, and generates detection level schedule data for optimizing the power supply abnormality detection range in, for example, one hour unit based on the analysis result. I do. Note that other environmental information such as the environmental temperature may be appropriately considered.

When AC power is supplied to a load device, the electrical characteristics of the load generally change due to an increase or decrease in the number of load devices, and the voltage level and frequency of the AC power also change. Therefore, the electric power company predicts such a load fluctuation based on past data and performs control so as to keep the quality of commercial electric power constant. However, power plants in factories are often designed on the assumption that the load is operating in a predetermined state.
Therefore, in many cases, control equipment for keeping the voltage level and frequency of such AC power constant is not provided. As a result, the power supplied from the power plant in the factory may fluctuate greatly between the daytime when the load device is operating and the nighttime when the load device is stopped.

For example, when it is determined based on the log data of the input voltage that there is a time period in which the input voltage is constantly higher than the voltage of the general commercial power, the voltage abnormality detection range in that period is determined. Is set higher than other time zones. If it is determined that there is a time zone in which the voltage abnormality is constantly reduced, the voltage abnormality detection range in that period is set lower. In FIG. 3, normally, "100
V ± 10% "
From 8:00 p.m. to 6:00 in the morning, the upper limit level of the voltage abnormality detection is changed to “100 V + 20%”. The center value (100 V in this example) may be adjusted instead of widening the range (plus / minus range).

With these settings, it is possible to appropriately secure a margin between the input voltage and each detection voltage in accordance with a change in the AC power input to the input terminal 4. It is possible to prevent switching to power supply from power storage member 14 based on an instantaneous voltage change or the like. Thus, the number of times the power storage member 14 is wasted can be reduced, and the life of the power storage member 14 can be extended.

The control unit 20 of the computer 1 transmits a transfer program 28 based on inter-program communication of the log analysis program 27 or a subsequent timer interrupt.
Execute The various setting data 30 stored in the data storage unit 23 is transferred to the data storage unit 12 of the microcomputer 13 and stored.

When the setting data 30 is transferred to the data storage unit 12 by the transfer program 28, it is better to ask the user prior to the processing. As a result, the user himself can use the optimized data under his / her responsibility.

Thus, the microcomputer 13
Operates in each operation mode based on the new setting data 30 optimized based on the log data 29, and periodically monitors an input voltage or the like input to the input terminal 4, and If an abnormality occurs, a process of switching the two-input switch 7 to another selection contact 10 is performed.

The above embodiment is a preferred embodiment of the present invention, but can be appropriately modified and implemented without departing from the gist of the invention. For example, in this embodiment,
In the load device (computer 1) connected to the output terminal 5, log data 29 is generated, and various setting data 30 is generated based on the log data 29. The same processing may be performed in the body device, or the same processing may be performed in the uninterruptible power supply 3.

However, as in the present embodiment, as a program that operates on a device different from the uninterruptible power supply 3,
The log accumulation program 26 and the log analysis program 27
By providing a program for setting the uninterruptible power supply 3 including the transfer program 28 and the uninterruptible power supply 3, the above detailed service can be provided at low cost (with high economy) without changing the hardware of the uninterruptible power supply 3 itself. It is possible to provide.

Further, in the uninterruptible power supply 3 generally sold, the power supply must be monitored repeatedly in a short cycle, and the current microcomputer used for such a purpose. Considering the processing capacity of the above, when performing the same processing in the uninterruptible power supply 3, it is better to newly incorporate a microcomputer as a control unit separately from the microcomputer 13. Thereby, optimization can be performed without impairing the original function (monitoring function and the like) of the uninterruptible power supply 3.

Also, in this embodiment, various setting data 30 are obtained based on the information of the AC power input to the input terminal 4 and the load power output from the output terminal 5. Alternatively, these may be obtained using environmental data such as temperature and humidity. In particular, when an absolute value or the like is set based on the log data 29 as in the case where the set value of the voltage detection range is obtained as described above, the log data 29 at each time is corrected using such environmental data. It is good to use above for the arithmetic processing. Although the environmental data used here may be detected by a sensor (not shown) incorporated in the uninterruptible power supply 3,
The information may be obtained from a weather information service on the Internet (not shown) on the side.

A system, a setting program, and a computer-readable recording medium recording the setting program can be obtained.
