Description

Apparatus for notifying the occurrence of the failure of the PS by using the SMP using the SMS {APPARATUS FOR SENDING SMS WHEN UPS FAILS}

The present invention relates to a device for notifying a user in real time of a failure or power failure occurring in a UPS (UNINTERRUPTIBLE POWER SUPPLY).

Uninterruptible power supply (UPS) refers to a device that provides uninterrupted alternative power in the event of a power outage of commercial power supplied to general customers by KEPCO. UPS is used when the power supply is unexpectedly interrupted or an excessive voltage drop occurs due to an accident. Normal power is supplied. However, in the conventional uninterruptible power supply, since the administrator cannot know whether the UPS is operating normally, the administrator should always check the switching to the normal line, and when the control failure occurs, the administrator cannot respond immediately if the manager is not in the field. Many.

The present invention has been made in order to overcome the above-mentioned disadvantages to provide a system that connects the UPS to the network using the SNMP protocol to notify the server through the network in the event of a failure and the server to notify by SMS to enable immediate notification. It aims to do it.

In order to achieve the above object, there is provided a UPS failure notification system using SMS, one or more UPS system including a NetAgent (SNMP) using SNMP protocol; Management server connected through the network with the UPS system, The management server includes a TRAP receiver for receiving a TRAP signal transmitted from the net agent; DB processing unit for distinguishing a target to send SMS according to the TRAP;

Management server including an SMS processing unit for requesting the SMS transmission to the SMS server; And may receive a request from the management server may include an SMS server for sending the SMS.

 It may further include a failure determination unit for determining the type of failure according to the TRAP.

The apparatus may further include a test unit for testing the TRAP.

The fault determining unit may distinguish the fault signal from the normal operation start signal from the TRAP signal.

The system as described above has the effect of providing a system that can identify the UPS failure in real time.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention. The present invention relates to an SMS service using SNMP (Simple Network Management Protocol) in a UPS. SNMP refers to a communication protocol for easier management of network devices. Figure 1 shows an embodiment according to the present invention, the UPS is a device for supplying a stable power to the computer room, if there is a problem this can be a fatal situation in the computer room environment, the conventional system is constantly checked by the system administrator Failure to do so could not detect a problem with the UPS and could not identify the problem in real time. The present invention overcomes these shortcomings by allowing the UPS to notify SNMP Trap / Notification, a non-connection type one-way communication, by sending a notification to SMS.

To this end, as shown in FIG. 1, a UPS is connected using a network, which may be a public network such as the Internet or a virtual private network such as a VPN. The UPS communicates with the UPS management server using the SNMP protocol while being connected through a network. For this purpose, the UPS can be connected to the router using an SNMP agent. Since SNMP is a one-way communication service based on TCP / IP, only a UPS connected to the network using TCP / IP can receive the service. When using TCP / IP, the UPS uses an embedded web agent. Can be connected to a network, and NetAgent supports a variety of protocols, including simple contacts, which is very compatible.

In SNMP, TRAP is a one-way one-way communication that notifies the network management system when a device has a problem. In this case, SNMPv2 Notification has the same function as TRAP of SNMPv1. It is recommended to use SNMPv2 as a standard for security reasons.

When TRAP occurs in SNMP, these events are notified to the UPS management server. The UPS management server checks whether the corresponding TRAP is included in the SMS dispatch list and checks the sending address of the corresponding TRAP. In this case, the contents are transmitted to a predetermined telephone number.

In the present invention, there is no change or addition of hardware components when adding an SMS function, and all functions are implemented as s / w in the management server. In addition, even if a network management system is already used (FMS, NMS, etc.), no change or addition of hardware or software is required, and the network function is added to the UPS only when the management system is not used. That is, simply install the SNMP agent on the UPS. In addition, since it uses SNMP, which is a standard protocol, it is not limited to UPS models, and there is no conflict with existing systems depending on the communication method, and existing networks or facility management networks can be used as they are, and no change is required for communication networks. There is no communication restriction for configuring local area network by one-way communication. In general, data is requested first, but in case of TRAP, data is sent from the device to a predetermined server only in special cases where the device has a problem. Equipment in the network can also communicate. It also operates only when an event occurs, so even if the UPS is running, it does not normally cause traffic, and only data is transmitted for a very short time when the event occurs. The general management system is designed to continuously monitor / monitor the normal situation, but such events can occur only once or twice a year on average and even on average due to internal facilities. Because it is only about a few times, it does not cause the problem of increasing traffic.

In addition, since the existing management system is used as it is, no separate management cost is required, and even if a separate management system is not configured, the network manager can monitor the network, thereby eliminating the need to visit the UPS installation site.

Components of the management server according to the present invention includes a TRAP receiver, a DB processing unit for retrieving the DB and bringing data, an SMS processing unit providing a SMS to the SMS server and a test unit for processing TRAP for testing. The element may be implemented s / w. These components are controlled by the control unit and a block diagram related thereto is shown in FIG.

If there is more than one administrator, you can search the DB to send SMS to all administrators, and the administrator who has received the SMS can notify the management server that the management server has been notified of the failure by using the preset SMS receiving number. When the reply comes to the receiving number, the management server does not notify another SMS for a certain time. However, if a failover notice does not come from the UPS after a period of time has elapsed, then all administrators can once again be notified of the failure. Therefore, SMS notification will be continued until failover is over. In addition, the completion of the failover can be completed when the administrator who first notified the SMS reception sends a recovery completion message to the management server.

The SMS can be sent to multiple managers, and if it is sent to multiple managers, it can be decided in advance which manager will handle the case. You can let them know.

In particular, since SMS or SNMP protocols are one-way communication, it is difficult to check whether proper processing has been performed. However, when the UPS is operating normally, the UPS can notify the management server through the network to inform the completion of the treatment. This is handled by the failure judgment part of the management server.

In addition, the DB may be managed by the DBMS and may include a table in which SNMP access points are registered and a table in which Internet accessors are registered.

The management server and the DB can be managed through a web interface. The user can log in and log out to input, search, edit, and delete data of the DB and display management data accordingly.
