Generally, a battery power supply is provided.
[0003]
An assembled battery in which several to several tens of storage batteries are connected in series is a system that backs up various systems such as communication equipment in terms of power in the event of a power failure (when commercial power supply is cut off) due to damage or other circumstances. is there. The storage battery used here has an aging deterioration inherent to the battery performance, but usually has a life of several years or more as long as the number of power failures is small.Conventionally, it has been considered that periodic replacement should be performed every few years. Was.
[0004]
However, with the rapid advancement of communication systems and information networks and the sharp increase in the frequency of use, malfunctions such as interruption of communication services and computer equipment stoppage due to power supply equipment failures directly lead to social problems. It is in.
[0005]
Accordingly, the present applicant proposes a system (Japanese Patent Application No. 9-369677) for measuring the remaining amount of an auxiliary battery that functions during a power failure, and based on the measurement result, performs maintenance management of power supply equipment supplied to load equipment. (Japanese Patent Application No. 2001-311583).
[0006]
A system (maintenance management method for a storage battery) proposed in Japanese Patent Application No. 2001-311583 for centrally maintaining and managing the state of a battery pack that compensates for power such as a power outage while maintaining and operating power equipment at a plurality of stations is an invention. Can be schematically shown in FIG.
[0007]
That is, data is transferred to the management center 3 via the communication line 2 such as the Internet on the assumption that the states of the assembled batteries 1 of a plurality of stations are monitored. Then, the diagnosis of the assembled battery 1 is performed using the diagnostic device 4 provided in the management center 3, mainly the remaining amount (performance state) of the storage battery is determined, and based on the result, the necessity of maintenance of the assembled battery 1 is determined. .

Such a maintenance management method is less likely to cause a special problem when the number of diagnostic processes to be handled in the management center 3 is relatively small.
[0011]
However, when it is necessary to handle a large number of performance diagnostics relating to the remaining amount of the storage battery simultaneously and in parallel, for example, when a power outage accident occurs in a wide area at the same time, prompt and accurate judgment on the storage battery capacity is required. In such a situation, if the remaining battery level of each facility is individually determined by the management center 3 at a remote location, there may be a case where the speedy diagnostic processing is hindered.
[0012]
In addition, when data relating to the state of the battery pack 1 for power supply compensation of each power supply facility is transmitted to the management center 3 via a general public line such as the Internet provided for public use, it is particularly confidential. There is a danger that the raw data of the storage battery in equipment with a high level of leakage will leak outside.
[0013]
Therefore, an object of the present invention is to realize data collection and processing relating to a battery pack in a large amount, quickly, and under conditions of high confidentiality.

[0021]
In addition, it is not necessary to restrict such use of the client (50) that wants to send the storage battery measurement result (raw data) to the maintenance management device (mobile service center) 20 via the public line P. Collection and management of measurement data via the general Internet public line P can also be performed.
[0022]
However, in order to realize the collection / management of the measurement data using the Internet public line P, it is necessary to ensure high confidentiality regarding a large amount of stored data obtained through the wireless communication line W. This is described below.
[0023]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 illustrates an embodiment of a maintenance management system for an auxiliary power supply battery according to the present invention. First, the overall configuration will be described.
[0024]
Reference numeral 10 denotes a monitoring device for a battery pack (hereinafter, referred to as a battery monitoring device) for compensating for a power failure while maintaining and operating the power equipment at a plurality of stations. And a maintenance management device (hereinafter referred to as a mobile service center) that collectively manages the battery status of each facility.
[0025]
The transfer of the measurement data from the battery monitoring device 10 to the mobile service center 20 is performed via the packet wireless switching network 29 using an appropriate portable wireless terminal such as a mobile phone.
[0026]
R is a router on the mobile service center 20 side. 40 and 50 are client terminal devices that use the mobile service center 20. The terminal device (C-CP1) denoted by reference numeral 40 is a computer device used for browsing various data of the battery status processed and edited in the mobile service center 20 and receiving an emergency alert in some cases. The terminal device (C-CP2) denoted by reference numeral 50 is for realizing a data storage and browsing request to the mobile service center 20 via a public line P using the Internet.
[0027]
The terminal device 50 includes a measuring unit 53 for measuring the remaining amount of the storage battery 51 as an equipment facility, and sends measurement data from the measuring unit 53 to the mobile service center 20 via a public line P using the Internet. . The mobile service center 20 performs appropriate processing and editing on the measurement data transmitted from the terminal device 50, and discloses the processed data in response to a data browsing request from the terminal device 50. An emergency alert is issued to the terminal device 50 using P.
[0028]
The battery monitoring device 10 includes at least an assembled battery (storage battery) 11 and a measuring unit 12 for measuring a state of the assembled battery (storage battery) 11. It is desirable to provide a measurement data storage unit 14 for temporarily storing measurement data in the measurement unit 12. Further, a data transmission unit 15 is provided for transmitting, for example, numerical data and the like accumulated in time series to the mobile service center 20 at predetermined intervals in the measurement data storage unit 14. Reference numeral 17 denotes an emergency alarm monitoring unit.
[0029]
The detection / transmission timing (interval) of the measurement data may be appropriately set, for example, to 15 seconds, 30 seconds, 60 seconds, 5 minutes, or 10 minutes. In a normal case, it is sufficient to detect / transmit the measurement data every 5 minutes. However, when the stop of the main power supply and the rapid consumption of the battery pack (storage battery) 11 due to a lightning strike or the like can be detected, the mobile service such as switching the data detection / transmission timing to 3 minutes or less, preferably every 60 seconds. It is desirable that the processing timing can be automatically switched so that the center 20 can perform optimal data collection and analysis.
[0030]
It is not always necessary to synchronize the measurement timing relating to the life of the assembled battery (storage battery) 11 with the transmission timing (interval) of the measurement result. If the measurement interval for the remaining amount is equal to or longer than the data transmission interval, the processing interval and the like may be appropriately adjusted.
[0031]
The alarm monitoring unit 17 provides a mobile service via the data transmission unit 15 when an urgent warning needs to be issued, for example, when the standard of the battery pack (storage battery) 11 in the measurement unit 12 falls below a predetermined threshold. This is a means for notifying the center 20 of appropriate warning contents. The detection items of the alarm monitoring unit 17 are not limited to the measurement results of the remaining amount measurement unit 12. For example, it is possible to provide a function of monitoring the entire equipment including fluctuations in the voltage and current values of the main power supply, and detection values from various sensors provided in the power supply system and the equipment main body. It is desirable to implement centralized monitoring.
[0032]
The mobile service center 20 includes a measurement data storage unit 21 for storing data of the remaining amount measurement unit 12 received via the packet radio switching network 29, and an edit storage unit 23 for providing various information to clients.
[0033]
The edit storage unit 23 has various functions. The most important function is to store the processing data for releasing the data in the measurement data storage unit 21 in response to a browsing request from the client. Other functions include, for example, technical matters for the client. In some cases, a function of directly sending an alarm to the terminal device 40 (50) based on an email transmission of various messages and an emergency alert from the alert monitoring unit 17 without passing through the edit storage unit 23 may be provided. . A symbol D indicated by a dashed line exemplifies a signal line when an emergency alert is immediately issued to the terminal device 40 (50) of the client. Reference numeral 24 denotes a service providing unit for transmitting data in the editing storage unit 23 to the outside in response to a browsing request from a client.
[0034]
Reference numeral 25 denotes an administrator control unit (an internal terminal device for the administrator) for appropriately processing and editing the data in the measurement data storage unit 21 by operating the editing storage unit 23. Reference numeral 26 denotes an internal server device, which provides necessary information and the like to the administrator control unit 25 as needed.
[0035]
The administrator control unit 25 may edit and process the data in the measurement data storage unit 21. This is mainly performed by converting the raw data into an easy-to-view format and processing the meaning of the numerical data more easily. It is the purpose. It is not intended to edit and process inaccurate semantic content. This system handles the remaining data of the auxiliary battery in various facilities, but this raw data is often the data that should be kept confidential, and even if it is a request from the client, the raw data can be viewed as it is It is not preferable to expose the client to an unusual state, and it is difficult to decipher the meaning of the measurement result even if the raw data is browsed and provided.
[0036]
All the configurations of the mobile service center 20 described above are arranged in a protected area of a browsing restricting unit (hereinafter, a firewall) 30 for preventing unauthorized access from the outside. The browsing request of the client 40 (50) is made through the firewall 30. The transfer of the measurement data from the client 50 is also performed through the firewall 30. In this case, in order to protect the data storage unit 21, which is an internal facility of the mobile service center 20, from unauthorized access, for example, a confidentiality confirmation device 31 such as a proxy server is provided according to a standard method of system construction.
[0037]
Further, a service providing unit 33 for responding to a browsing request from the client 50 and a data storage requesting unit 35 for responding to a request for managing and storing measurement data from the client 50 are provided inside the proxy server constituting the confidentiality confirmation device 31. Or separately from the proxy server. In any case, the confidentiality confirmation device 31, the service providing unit 33, and the data storage requesting unit 35 are arranged so as to be separated from the measurement data storage unit 21 via the firewall 30. Completely block unauthorized access to. The service providing unit 33 and the data storage requesting unit 35 constitute a data exchange unit 39 according to the present invention.
[0038]
Therefore, according to this configuration, the state of the storage battery of the power supply equipment can be measured on the power supply equipment side of each station, and the measurement result can be stored in the mobile service center 20 via the wireless communication line W. This makes it possible to quickly process a large amount of data relating to the battery in various emergency situations such as when a power failure occurs.
[0039]
The measurement data (not limited to the remaining amount of the auxiliary battery) sent from each facility is measured via the wireless communication line W and stored in the measurement data storage unit 21 in the mobile service center 20 for storing the measurement data. Is protected from unauthorized access from the outside by the firewall 30, so that the confidentiality of various measurement data can be highly guaranteed.
[0040]
In addition, even in response to a browsing request from an external client (40, 50), data edited and edited into an easy-to-view format without disclosing raw data in the measurement data storage unit 21 via the edit storage unit 23. It is released only to the clients (40, 50). It is desirable to provide a means for necessary security check, such as ID collation, for the browsing request of the client (40, 50). The editing storage unit 23 and the service providing unit 24 are also areas protected by the firewall 30. However, due to the structure of the mobile service center 20, communication with the outside is established in the highly confidential measurement data storage unit 21 area. By completely separating from the edit storage unit 23 and the service providing unit 24, the security of the measurement data storage unit 21 itself can be significantly increased.
[0041]
The mobile service center 20 and the battery monitoring device 10 may perform wired data transmission / reception as long as security can be assured, such as a dedicated line. However, it is desirable to use the wireless communication line W in consideration of the installation introduction cost and the like.
[0042]
In addition, since the data exchange unit 39 allows the storage (storage / management) of the measurement data of the storage battery 51 and the data browsing after the editing and processing through the general public line P, the confidentiality is relatively low. Various data of the client can be handled at the mobile service center 20 at any time. For example, it is a water meter, a gas meter, an electric meter in an apartment, a housing complex, a detached house, or the like, or a measured value of a sensor in various facilities. Of course, these data can also be sent to the mobile service center 20 via the packet radio switching network 29 and stored.
[0043]
【The invention's effect】
As described above, according to the maintenance management system of the present invention, it is possible to realize data collection relating to the state of the assembled battery under a condition of a large amount, quickness, and high confidentiality.
