Address) is supplied to the server identification unit 145. In addition, the reception part 144 supplies the information which shows the server which made the report to the server specific | specification part 145, when the information which shows the server which notified is included with the signal which shows having detected the water drop. In addition, when receiving the device group information together with a signal indicating that a water droplet has been detected, the receiving unit 144 also supplies the device group information to the server specifying unit 145 together with information indicating the reported server.

  The storage unit 151 is a storage unit realized by the memory 15. The storage unit 151 stores server installation environment registration information. The server installation environment registration information is information in which information indicating each server is managed for each environment (for example, a device group) in which the server is installed. In the present embodiment, the server installation environment registration information includes, for example, information that the server group A includes servers A1, A2, and A3, and the device group B includes servers B1, B2, and B3.

  When the server specifying unit 145 receives the information indicating the server that has made a report from the receiving unit 144, the server specifying unit 145 refers to the server installation environment registration information stored in the storage unit 151 and has the same area (the same device group) as the server that has received the report. ). The server specifying unit 145 supplies information (for example, an IP address) indicating the specified server to the transmission unit 143.

  In addition, when the device group information is supplied from the receiving unit 144 together with the information indicating the reported server, the server specifying unit 145 includes the area code and IP address included in the device group information, and the server installation environment registration information. It may be configured to confirm whether or not the registered area code and IP address match.

  Further, the server specifying unit 145 checks whether the IP address included in the device group information matches the IP address registered in the server installation environment registration information, and specifies the matching server as a server in the same area. It may be configured to. Thereby, even if there is an error in the device group information, by referring to the IP address, it is possible to specify a server in the same area as the server that made the report.

  The transmission unit 143 transmits a power-off instruction all at once to the servers identified by the server identification unit 145 via the communication I / F 16.

(System operation)
Next, with reference to FIGS. 4 to 6, a processing flow of the system according to the present embodiment will be described. 4 to 6 are flowcharts showing an example of the processing flow of the system according to the present embodiment. In the present embodiment, the case where fire prevention equipment (for example, a sprinkler) in the room A operates in the room in the region A shown in FIG. 1 will be described as an example. FIG. 4 shows the processing flow of the server A1, FIG. 5 shows the processing flow of the management manager 10, and FIG. 6 shows the processing flow of the other servers (servers A2, A3, B1 to B3).

  As shown in FIG. 4, it is confirmed whether or not the detection unit 231 of the server A1 has detected the intrusion of water from the air hole 21 (step S41). The detection unit 231 repeats step S41 until it detects water intrusion.

  When detection unit 231 detects water intrusion (YES in step S41), detection unit 231 notifies opening / closing unit 241 and transmission / reception unit 243 that water intrusion has been detected. When receiving the above notification, the opening / closing unit 241 moves the opening / closing member 221 by unlocking the lock member 222 and shields the air hole 21 (step S42). Then, the opening / closing unit 241 notifies the stop unit 242 that the air hole 21 has been shielded.

  When receiving the notification from the detection unit 231, the transmission unit 243 notifies the management manager 10 that water intrusion has been detected (step S <b> 43). And the transmission part 243 notifies the stop part 242 that it reported. Note that steps S42 and S43 may be executed in reverse order or simultaneously. Further, the transmission unit 243 may be configured to report after receiving a notification indicating that the air hole 21 is shielded from the opening / closing unit 241.

  After step S42 and S43 are complete | finished, the stop part 242 shuts down its own server (in this example, server A1) (power-off) (step S44), and complete | finishes a process.

  Next, a processing flow of the management manager 10 will be described with reference to FIG. As shown in FIG. 5, the receiving unit 144 of the management manager 10 confirms whether or not a notification has been received (step S51). The receiving unit 144 repeats S51 until the notification is received.

  After receiving the notification in step S43 described above, when receiving unit 144 receives the notification (YES in step S51), receiving unit 144 provides information indicating the notified server (for example, the IP address of the server that made the notification). The data is supplied to the server specifying unit 145. When receiving the device group information together with a signal indicating that a water droplet has been detected, the receiving unit 144 also supplies the device group information to the server specifying unit 145 together with information indicating the notified server.

  When the server specifying unit 145 receives information indicating the server that has made a report from the receiving unit 144, the server specifying unit 145 refers to the server installation environment registration information stored in the storage unit 151, and selects a server in the same area as the server that has received the report. It identifies (step S52). Then, the server identification unit 145 supplies the identified server to the transmission unit 143.

  The transmitting unit 143 transmits a power-off instruction to the server specified by the server specifying unit 145 (step S53), and ends the process.

  In this example, a power-off instruction is transmitted to the servers A2 and A3 in the same area A as the server A1. For the servers B1 to B3 arranged in the area B, since it is determined that it is not the same area as the server A1 notified by the server specifying unit 145, the power-off instruction is not transmitted.

  Next, with reference to FIG. 6, the flow of processing of servers other than the notified server (in this embodiment, server A1) will be described. As shown in FIG. 6, the receiving unit 344 (in the case of servers A2, A3, B1, and B2) and the receiving unit 244 (in the case of server B3) other than the server A1 (hereinafter referred to as other servers) are powered off. It is confirmed whether or not an instruction has been received (step S61). Receiving unit 344 and receiving unit 244 repeat step S61 until a power-off instruction is received.

  When receiving unit 344 and receiving unit 244 receive the power-off instruction (YES in step S61), receiving unit 344 and receiving unit 244 confirm whether or not the own server has shielding mechanism 22 (step S62). ). In addition, the confirmation method of whether the own server is equipped with the shielding mechanism 22 is performed by referring to the setting information of the own server. Note that the receiving unit 344 and the receiving unit 244 may confirm whether the sensor 23 is installed instead of the shielding mechanism 22.

  When shielding mechanism 22 is provided (that is, the configuration of server A1 and server B3) (YES in step S62), opening / closing unit 241 releases lock member 221 by unlocking lock member 222. The air hole 21 is shielded (step S63). In the present embodiment, the servers that are instructed to turn off the power are the server A2 and the server A3, and therefore S63 is not performed in this example.

  After step S63, or when shielding mechanism 22 is not provided (that is, servers A2, A3, B1, and B2) (NO in step S62), stop unit 242 or stop unit 342 The power is turned off (step S64). In this example, since the server A2 and the server A3 are targeted, the stop unit 342 of the server A2 and the server A3 respectively powers off its own server.

  As a result, the servers A1 to A3 are shut down, and the servers B1 to B3 that are not notified of the power-off instruction from the management manager 10 are in an operating state.

(effect)
As described above, system 100 according to the present embodiment is arranged in a plurality of areas (areas A and B), and a plurality of servers including stop unit 242 or stop unit 342 for shutting down its own device. (Servers A1 to A3, B1 to B3) and a management manager 10 that manages each of the servers A1 to A3 and B1 to B3.

  Of the plurality of servers arranged in each area, at least one server (in this embodiment, server A1 and server B3) has an air hole 21 in the exterior, and a sensor 23 that detects water droplets, When the sensor 23 detects a water droplet, the transmission unit 243 that transmits a notification indicating that the water droplet has been detected to the management manager 10 and an opening / closing unit 241 that closes the air hole 21 when the sensor 23 detects the water droplet are provided. . When the management manager 10 receives the notification from a server that has detected a water droplet by the sensor 23, the management manager 10 is a server that is arranged in the same area as the server that has transmitted the notification and is different from the server that has transmitted the notification. On the other hand, a transmission unit 143 that transmits an instruction to shut down is provided.

  The server stop unit 242 that has detected the water drop shuts down the server when the sensor 23 detects the water drop, and the server that has detected the water drop among one or a plurality of servers arranged in each region, When the server stop unit 342 disposed in the same area receives the shutdown instruction, the server shutdown unit 342 shuts down the server.

  As a result, the server that detects the water droplets can prevent the water from entering further, and can safely turn off the server power. Further, the server power source that is located in the same area as the server that detected the water droplets can be turned off. It can be safely dropped.

  Therefore, according to system 100 according to the present embodiment, water can be prevented from entering, and the server can be used more safely.

(Modification)
In the system 100 according to the present embodiment, the configuration in which each server has one server having the air hole 21 and the shielding mechanism 22 has been described, but the present invention is not limited to this. All of the servers arranged in each region may have the air holes 21 and the shielding mechanisms 22, or any number of servers may have the air holes 21 and the shielding mechanisms 22.

  Even in such a configuration, since the management manager 10 performs power management of all servers, when a server in a certain area detects a water drop, the management manager 10 A power-off instruction can be transmitted. Thereby, the server arrange | positioned in the room provided with the fire prevention equipment can be utilized more safely.

In the present embodiment, a case will be described as an example in which fire prevention equipment (for example, a sprinkler) in the room A operates in the room in the area A shown in FIG. 7 and the server A1 detects water droplets. FIG. 9 shows the processing flow of the server A1 at this time, and FIG. 10 shows the processing flow of the other servers (servers A2, A3, B1 to B3).

  As shown in FIG. 9, it is confirmed whether or not the detection unit 231 of the server A1 has detected the intrusion of water from the air hole 21 (step S91). The detection unit 231 repeats step S91 until it detects water intrusion.

  When detection unit 231 detects water intrusion (YES in step S91), detection unit 231 notifies opening / closing unit 241 and transmission / reception unit 243 that water intrusion has been detected. When the opening / closing unit 241 receives the notification, the opening / closing member 221 is moved by releasing the lock of the locking member 222 to block the air hole 21 (step S92). Then, the opening / closing unit 241 notifies the stop unit 242 that the air hole 21 has been shielded.

  When the transmission unit 243 receives the notification from the detection unit 231, the transmission unit 243 broadcasts and searches for a server in the same area as the local server (server A1). Specifically, the transmission unit 243 has information (for example, area) indicating the area where the server is installed for all servers (servers A2, A3, B1 to B3 in this example) connected via the network. Code (IP address) transmission instruction (broadcast). Then, the receiving unit 244 of the server A1 receives the information transmitted from the transmitting unit 243 of each server, and supplies the received information to the server specifying unit 245. Based on the information supplied from the receiving unit 244, the server specifying unit 245 of the server A1 specifies a server in the same area as the own server, and supplies information indicating the specified server to the transmitting unit 243 of the server A1 ( Step S93).

  The transmission unit 243 transmits a power-off instruction to the server specified by the server specifying unit 245 (multicast). Then, the transmission unit 243 of the server A1 notifies the stop unit 242 that the power-off instruction has been multicast transmitted (step S94).

  Step S92 may be performed after step S94, or may be performed simultaneously with step S93 or S94.

  Upon receiving the notifications from the opening / closing unit 242 and the transmission unit 243, the stopping unit 242 of the server A1 shuts down (powers off) its own server (server A1 in this example), and ends the processing (step S95).

  In the present embodiment, the transmission unit 243 broadcasts and searches for a server in the same area as its own server, and the server specifying unit 245 specifies a server in the same area based on the search result. An explanation was given as an example. However, the present invention is not limited to this, and the server specifying unit 245 may specify servers installed in the same area based on the device group information stored in the storage unit 251.

  Further, for example, a case will be described in which each server is connected to a different segment in a different area, and when the transmission unit 243 of each server performs broadcast transmission, an instruction is transmitted only to servers in the same segment. In this case, the transmission unit 243 of the server that has detected the water droplet may perform a process of broadcasting the power-off instruction instead of the above-described steps S93 and S94. In this case, since only the servers arranged in the same area are in the same segment, the power-off instruction is transmitted only to the servers arranged in the same area.

  Thus, in this example, the power-off instruction is transmitted to the server A2 and the server A3 that are in the same area A as the server A1. The power-off instruction is not transmitted to the servers B1 to B3 arranged in the area B.

  Next, with reference to FIG. 10, the flow of processing of servers other than the server that has detected water droplets (server A1 in this embodiment) will be described. As shown in FIG. 10, the receiving units 244 of other servers confirm whether or not a power-off instruction has been received (step S101). The receiving unit 244 repeats step S101 until a power-off instruction is received.

  When receiving unit 244 receives the power-off instruction (YES in step S101), opening / closing unit 241 releases lock member 222 to move opening / closing member 221 and shield air hole 21 (step S102). ).

  After step S102 ends, the stop unit 242 turns off the power of the server itself (step S103). In this example, since the server A2 and the server A3 are targeted, the stop unit 242 of the server A2 and the server A3 respectively powers off its own server.

  As a result, the servers A1 to A3 are shut down, and the servers B1 to B3 that are not notified of the power-off instruction are in an operating state.

(effect)
As described above, system 200 according to the present embodiment is arranged in a plurality of servers (servers A1 to A3) that are arranged in a plurality of regions (regions A and B) and each have a stop unit 242 for shutting down its own device. , B1 to B3). At least one server among the plurality of servers arranged in each region has an air hole 21 in the exterior, and a sensor 23 that detects water droplets that have entered inside through the air hole 21, and a sensor When the water drop is detected, the opening / closing part 241 that closes the air hole 21, and when the sensor 23 detects the water drop, the server specifying part 245 that specifies a server arranged in the same area as the server is specified by the server specifying part 245. A transmission unit 244 that transmits an instruction to shut down the server.

  Then, the server stop unit 242 that has detected a water droplet shuts down the server when the transmission unit 243 transmits the instruction and the opening / closing unit 241 closes the air hole 21, and a plurality of servers arranged in each region Among them, the server stop unit 242 arranged in the same area as the server that detected the water drop shuts down the server when receiving an instruction to shut down.

  As a result, the server that detects the water droplets can prevent the water from entering further, and can safely turn off the server power. Further, the server power source that is located in the same area as the server that detected the water droplets can be turned off. It can be safely dropped.

  Therefore, according to system 200 according to the present embodiment, water can be prevented from entering and the server can be used more safely.
