BEST MODE FOR CARRYING OUT THE INVENTION
According to the present invention, a large current that cannot be generated during normal operation due to the effect of lightning strikes flows into each physical line (LAN (local area network), serial cable, private line, etc.) (generally called lightning surge). At the same time, each device that is the target of lightning protection, such as a computer device connected to the network, is protected from the lightning surge, and the propagation range of the lightning surge in the system and the status of the protector are changed by wireless technology (for example, This is to notify a lightning monitoring monitor using a wireless LAN) and the Internet so that the situation of lightning can be visually recognized.
[0008]
FIG. 1 is a block diagram showing a configuration example of an embodiment of a lightning status monitoring system to which the present invention is applied. By using the lightning status monitoring system, it is possible to provide lightning resistance and to immediately determine the influence of a lightning surge on the entire system.
[0009]
FIG. 1 shows an example in which this lightning status monitoring system is applied to a general computer device 10 connected to a LAN. As shown in the figure, the computer device 10 to be protected from lightning receives power from a communication line 51, which is a physical line for communication (LAN, serial, private line, etc.) used for network connection, and a power supply 50. All of the connections to which a lightning surge may flow in the event of a lightning strike, such as the supplied power supply line 52 and the grounding line 53 for Ground, are collectively housed in the station protector 20 at once, It is installed between each line.
[0010]
The station protector 20 has a function of detecting an overcurrent inflow due to lightning, a function of preventing an overcurrent inflow, and a function of wirelessly outputting alarm information such as a lightning situation. That is, the station protector 20 transfers the lightning situation to the lightning monitoring monitor 30 via the wireless LAN 100. The transfer of the alarm information to the remote lightning monitoring monitor 40 is performed using the Internet 200.
[0011]
The lightning monitoring monitor 30 and the remote lightning monitoring monitor 40 have a system configuration stored in advance in a storage device (not shown) based on information from the station protector 20 and the station protector 20 installed in another device (not shown). The lightning situation is reflected in the information, and information enabling visual determination of the lightning point and the lightning situation is output to a display screen (not shown).
[0012]
FIG. 2 shows screen examples of the lightning monitoring monitor 30 and the remote lightning monitoring monitor 40. In this example, terminals 1 to 7 and a router connected by a LAN installed in Building A, a terminal 1, host computers 1, 2 and a router connected by LAN installed in Building B, and a router installed in a factory building Terminals 1 to 7 and a router connected by the connected LAN are displayed. In addition, the display colors of the terminal that has received lightning and the terminal that has not received lightning are changed so that the terminal that has received lightning can be distinguished.
[0013]
The following lightning situation is displayed on the right side of the screen. "03/04/12 12:10:55 Overcurrent has flowed into the power supply system of Terminal 3 in Building A. (ping timeout)", "03/04/12 12:10:55 Terminal 4 in Building A Overcurrent has flowed into the power supply system (ping timeout), "03/04/12 12:10:55 Overcurrent has flowed into the power supply system of terminal 5 in Building A. (ping timeout)", "Ping timeout" 03/4/12/1212: 10: 56 The withstand voltage level of the terminal station connected to the Router in Building A has reached its limit. The arrester needs to be replaced. "
[0014]
From this screen, the system administrator can easily visually confirm the lightning situation of the entire system. In the case of this example, it can be seen that the terminals 3, 4, and 5 in the building A have been hit by lightning. In addition, it can be seen that the withstand voltage level of the terminal station 20 connected to the Router of Building A has reached the limit, and that the arrester 21 (FIG. 4) needs to be replaced.
[0015]
In the present system, it is necessary to install a station protector 20 in advance for each lightning protection target point, and to set up a lightning monitoring monitor 30 for receiving information transmitted wirelessly from the station protector 20.
[0016]
When lightning is actually generated in a state where the present system is incorporated in a user system (in this example, the computer device 10) and a lightning surge flows into the user system, the present system will be described later with reference to FIG. Performs such an operation. FIG. 3 is a flowchart showing the basic operation of the present system.
[0017]
FIG. 4 is a functional block diagram of the station protector 20. As shown in the figure, the present embodiment is functionally characterized by an arrester 21 that guards the computer device 10 inside the system from a lightning surge, an overcurrent passing outside and inside, and a deterioration in resistance of the arrester 21 itself. An alarm detection unit 22 for detecting, an alarm output SW 23 for passing the alarm information to the wireless control unit 24 while insulating the influence of lightning, a wireless control unit 24 for controlling transmission of the alarm information to the wireless LAN 100, and a wireless LAN 100 And a wireless interface unit 25 for sending alarm information to the wireless interface unit. In the case of this example, a predetermined one of the arresters 21 is provided between the ground line 53 and the computer device 10, and another predetermined one of the arresters 21 is a power input unit 61 to which power is input from a power supply line 52. Still another predetermined arrestor 21 is provided between a power supply output unit 62 from which power is output, and an interface unit 63 to which data is input from a communication line 51 and an interface unit 64 to which this data is output. It is provided in.
[0018]
Normally, a portion having a function of transmitting alarm information to the wireless LAN 100 is in a suspended state. Then, when any of the alarm outputs SW23 is turned on due to the inflow of a lightning surge, a portion having a function of transmitting alarm information to the wireless LAN 100 (for example, the wireless control unit 24, the wireless interface unit 25) becomes active, and the alarm is issued. Wireless transmission of information is started. That is, the alarm output SW23 is provided for each arrester.
[0019]
The alarm information transferred to the lightning monitoring monitor 30 is further transferred to the remote lightning monitoring monitor 40 via the Internet 200 as necessary. The lightning monitoring monitor 30 collects the alarm information transmitted from each station protector 20, and reflects the alarm information on the system configuration information stored in advance in a storage device (not shown). As a result, as shown in FIG. 2, information that visually indicates the lightning-receiving point and the lightning-receiving condition is output to the screen.
[0020]
Next, the operation of the present embodiment will be described with reference to the flowchart of FIG. First, in step S1, a lightning strike occurs and a lightning surge flows into the station protector 20, and in step S2, the alarm detection unit 22 detects the lightning surge inflow as a "lightning surge inflow alarm" and outputs a detection signal. Output to the alarm output SW23. Next, in step S3, the incoming lightning surge enters the arrester 21 and is absorbed by the arrester 21.
[0021]
However, if the arrester 21 absorbs a lightning surge, the arrester 21 may be damaged in some cases. Therefore, in step S4, the degree of damage check of the arrester 21 is constantly performed. This damage degree check is realized by incorporating the arrester function deterioration detection mechanism used in the general arrester 21 into the alarm detection unit 22. When the deterioration of the arrester 21 is detected in the damage degree check, the process proceeds to step S5, and a detection signal is output to the alarm output SW 23 as "alester breakage alarm".
[0022]
Also, in step S6, it is checked whether an overvoltage has been detected inside. As a result, when the lightning surge passes through the arrester 21 and reaches the internal interface (the interface unit 62), the process proceeds to step S7, where the alarm detection unit 22 detects the "overvoltage inflow alarm" and outputs the detection signal as an alarm output. Output to SW23.
[0023]
If the process in step S7 is completed, or if it is determined in step S4 that the arrester is not damaged, or if it is determined in step S6 that no overvoltage is detected inside, the process proceeds to step S8. In step S8, as described above, the alarm information (“lightning surge inflow alarm”, “arrestor breakage alarm”, “overvoltage inflow alarm”) output to the alarm output SW23 is immediately supplied to the wireless interface unit 25. Further, in step S9, under the control of the wireless control unit 24, each alarm information is transmitted from the wireless interface unit 25 to the lightning monitoring monitor 30.
[0024]
Next, in step S10, the lightning monitoring monitor 30 reflects the received alarm information on the system configuration information stored in advance in a storage device (not shown), and displays the respective alarm information on a display (not shown). Display the reflected system configuration information. This allows the user to check the lightning situation in the system in real time. Thereafter, the process returns to step S1, and the processes after step S1 are repeatedly executed.
[0025]
Next, the function of the station protector 20 will be described. First, regarding the type of the station protector 20, since there are various types of physical lines for communication (LAN, serial, private line, etc.), it is necessary to select the model of the station protector 20 according to each case. .
[0026]
Although the general station protector 20 has a function of detecting an overcurrent inflow due to lightning and a function of preventing an overcurrent inflow, the station protector 20 used in the present embodiment has, in addition to these functions, The greatest feature is that it has a wireless output function.
[0027]
As described above, by using the present embodiment, the computer devices and the like in the system are protected from the lightning surge, and further, even if the lightning surge passes through the arrester 21, the range affected by the lightning surge is confirmed. It is possible to specify the device in which the failure has occurred. In addition, it is also possible to confirm that the arrester 21 having the finite lightning limit is over the withstand voltage limit. In addition, since the alarm information transmitted from each arrester 21 by radio can be received and displayed by using the lightning monitoring monitor 30, the collective monitoring of the lightning status for the entire system is possible. And maintenance efficiency can be improved. Further, since the alarm information can be transmitted to the remote lightning monitoring monitor 40 via the Internet, it is possible to monitor the lightning situation in various places.
[0028]
It should be noted that the configuration and operation of the above embodiment are examples, and it is needless to say that the configuration and operation can be appropriately changed without departing from the spirit of the present invention.
[0029]
【The invention's effect】
As described above, according to the lightning status monitoring system according to the present invention, the arrester that suppresses the inflow of lightning surge into the equipment in the system includes the fact that the lightning surge has flowed, the deterioration state of the arrester, and the lightning surge , It detects that an overvoltage has flowed into a device inside the system, and wirelessly sends out alarm information, which can be displayed on the screen of a lightning monitoring monitor. As a result, it is possible to suppress the inflow of the lightning surge into the devices in the system, and to specify the location where the failure occurs due to the lightning surge even if the lightning surge passes through the arrester. In addition, it can be confirmed that the arrester has exceeded the resistance limit. In addition, collective monitoring of the lightning status of the entire system becomes possible. Further, since the lightning situation can be transmitted via the Internet, the lightning situation can be monitored at various places.
