  However, because the capacity of power stored in the power storage device of the uninterruptible power supply is limited, when the stored power is depleted, the power supply to the communication device stops and the operation of the connected communication device stops Resulting in. Here, for example, when a plurality of communication devices are connected to the uninterruptible power supply, some communication devices are concentrated by concentrating the power supplied to the plurality of communication devices to some communication devices. The operating time can be extended and the operating state can be maintained. Therefore, there is a demand for a technique for determining a communication device for which it is desirable to keep an operating state among a plurality of communication devices.

  Hereinafter, some embodiments of the present invention will be described in detail with reference to the drawings. In addition, the same code | symbol is attached | subjected to the corresponding element in several drawing.

  FIG. 1 is a diagram illustrating an exemplary power supply system 100. The power supply system 100 includes a SIP (Session Initiation Protocol) server 102 and a base 103. The base 103 may be, for example, a place where a communication facility such as a company office or a military base such as the Self-Defense Force is installed. The base 103 includes, for example, a router 111, a PoE (Power over Ethernet) switch 112, a power supply 113, an uninterruptible power supply 114, and a plurality of communication devices 115. The router 111 is connected to the network 105 outside the base 103 and mediates communication between the network 105 outside the base 103 and the network inside the base 103. The router 111 is connected to the PoE switch 112 via the communication line 120. The power supply 113 supplies power to the uninterruptible power supply 114 via the power supply line 122. For example, the uninterruptible power supply 114 supplies power from the power supply 113 to the router 111 and the PoE switch 112 when power is supplied from the power supply 113. Further, uninterruptible power supply 114 may charge power storage device 125 such as a battery provided in uninterruptible power supply 114 with the electric power from power supply 113. On the other hand, the uninterruptible power supply 114 supplies the power stored in the power storage device 125 to the router 111 and the PoE switch 112 when the supply of power from the power supply 113 is stopped due to, for example, a power failure. .

  The PoE switch 112 is connected to, for example, a plurality of communication devices 115 via an Ethernet (registered trademark) wiring 123, and mediates transmission / reception of data between the router 111 and the communication device 115. The PoE switch 112 supplies the power supplied from the uninterruptible power supply 114 to the plurality of communication devices 115 via, for example, an Ethernet (registered trademark) wiring 123. For example, the PoE switch 112 may stop supplying power to the communication device 115 by switching the switch.

  The communication device 115 may be a telephone, for example. In this case, the communication device 115 may connect to a communication device of a communication partner via a SIP server and execute a call.

  For example, the SIP server 102 may be a server that manages and controls an IP (Internet Protocol) telephone service using SIP (Session Initiation Protocol). The SIP server 102 manages, for example, data that associates user identification information such as a telephone number with information indicating the location on the network such as an IP address, and transmits the communication device 115 and the communication partner receiving the incoming call. The call information is mediated with the communication device 115.

  Here, for example, when a power failure occurs at the base 103 of the power supply system 100, the supply of power from the power supply 113 to the uninterruptible power supply 114 is stopped. In this case, the uninterruptible power supply 114 supplies the power stored in the power storage device 125 to the router 111 and the PoE switch 112. However, since the capacity of the power stored in the power storage device 125 of the uninterruptible power supply 114 is limited, when the power stored in the uninterruptible power supply 114 is depleted, the power to the communication device 115 is stopped and the communication The device 115 will stop.

  Here, for example, when a plurality of communication devices 115 are supplied with power from the uninterruptible power supply 114, the power is concentrated on some communication devices 115 and supplied to other communication devices 115. When the operation is stopped, the operation of some of the communication devices 115 can be maintained for a longer time. Therefore, for example, a priority indicating the degree of priority for continuing the operation is set for each of the plurality of communication devices 115. Then, for example, by stopping the supply of power from the uninterruptible power supply 114 to the communication device 115 having a low device priority, the operation of the communication device 115 having a high device priority can be continued. In the following description, the priority set for this communication device may be referred to as device priority. For example, the device priority may be set to a higher priority as the communication performed by the communication device is more important. For example, in companies and military forces such as the Self-Defense Forces, positions may be assigned to the personnel to which they belong. Higher personnel may have an important role in the armies of the companies or Self-Defense Forces to which they belong. high. Therefore, for example, a higher device priority is assigned to a communication device used by a person having a job title than a person having no job title, and a higher device priority is assigned to a communication device used by a person having a higher job title. Device priority may be set. In another example, the device priority may be set so that a higher device priority is assigned to a communication device as data transmitted through communication performed by the communication device is more important.

  However, it is assumed that the supply of power to the communication device 115 having a low device priority is stopped as described above. In this case, for example, the communication device 115 with a low device priority stops communication even if the communication device 115 with a high device priority is communicating with the communication device 115 with a high device priority. If the degree is high, the communication may be an important communication. Therefore, in the embodiment described below, communication is performed based on the device priority of the communication device 115 in communication connected to the uninterruptible power supply device 114 and the device priority of the communication device 115 of the communication partner in communication. Determine the priority of. And supply of the electric power from the uninterruptible power supply 114 is controlled based on the priority of communication. Therefore, for example, when a communication device 115 with a low device priority connected to the uninterruptible power supply 114 is communicating with a communication device 115 with a high device priority, the communication device 115 with a high communication priority is high. The priority of communication increases according to the priority. Therefore, for example, it is possible to suppress the power supply to the communication device 115 having a low priority during communication with a communication partner having a high priority from being stopped. In the following description, the communication priority determined based on the device priority of the communication device in communication and the device priority of the communication device 115 of the communication partner may be referred to as a communication priority.

The base 203 may be, for example, a place where communication facilities such as a company office or a military base such as the Self-Defense Force are installed. The base 203 includes, for example, a router 211, a PoE switch 212, a power source 213, an uninterruptible power supply 214, and a plurality of communication devices 215. The router 211 is connected to a network 205 outside the base 203 and mediates communication between the network 205 outside the base 203 and the network inside the base 203. The router 211 is connected to the PoE switch 212 via the communication line 220. The communication line 220 may be, for example, a cable such as RJ-45.

The uninterruptible power supply 214 is a power supply apparatus having a function of storing the power supplied from the power supply 213 in a power storage device 225 such as a battery provided in the uninterruptible power supply 214 and supplying the stored power to other devices. is there. For example, when power is supplied from the power supply 213, the uninterruptible power supply 214 supplies the power from the power supply 213 to the router 211 and the PoE switch 212. Further, uninterruptible power supply 214 may charge power storage device 225 with power from power supply 213. On the other hand, the uninterruptible power supply 214 supplies the power stored in the power storage device 225 to the router 211 and the PoE switch 212 when the supply of power from the power supply 213 is stopped due to, for example, a power failure. In addition, the uninterruptible power supply 214 according to the first embodiment is connected to the PoE switch 212 via the communication line 220. For example, information such as the power supply state from the power supply 213 is transmitted to the power supply control apparatus 201. Notice.

  The PoE switch 212 is connected to, for example, a plurality of communication devices 215 via an Ethernet (registered trademark) wiring 223, and mediates transmission / reception of data between the router 211 and the communication device 215. The PoE switch 212 supplies the power supplied from the uninterruptible power supply 214 to the plurality of communication devices 215 via, for example, the Ethernet (registered trademark) wiring 223. For example, the PoE switch 212 may stop supplying power to the communication device 215 by switching the switch. The Ethernet (registered trademark) wiring 223 may include, for example, a communication line 220 and a power supply line 222.

  In the first embodiment, the communication device 215 may be a device having a function of making a telephone call or the like. However, the embodiment is not limited to this, and the communication device 215 may be an apparatus having other communication functions including a personal computer as exemplified in a second embodiment described later. In the first embodiment, the communication device 215 may connect to the communication partner communication device 215 via the SIP server 202 and execute a call.

  The SIP server 202 may be a server that manages and controls an IP telephone service using SIP, for example. The SIP server 202 manages, for example, data that associates user identification information such as a telephone number with information indicating the location on the network such as an IP address, and transmits the communication device 215 and the communication partner receiving the incoming call. The call information is mediated with the communication device 215.

  The power supply control device 201 controls the PoE switch 212 based on, for example, information on the amount of power stored in the power storage device 225, information on the supply of power from the power source 213, and the communication state of the communication device 215, and performs communication. Power supply to the device 215 may be controlled. In FIG. 2, one base 203 is illustrated, but the power supply control apparatus 201 may control power supply to a plurality of communication devices 215 included in the plurality of bases 203.

  FIG. 3 is a diagram illustrating a functional block configuration of the power supply control apparatus 201 according to the first embodiment. The power supply control device 201 includes, for example, a control unit 300, a storage unit 310, and a communication unit 320. The control unit 300 includes functional units such as a determination unit 301 and a power supply control unit 302, for example. The storage unit 310 of the power supply control apparatus 201 may store information such as base information 500 and 800, power supply device priority information 900, and power supply communication priority information 1000, which will be described later. The communication unit 320 transmits / receives data via the network 205 in accordance with instructions from the control unit 300. Details of these functional units and details of information stored in the storage unit 310 will be described later.

  FIG. 4 is a diagram illustrating power supply information 400. The power supply information 400 is information that the uninterruptible power supply 214 notifies the power supply control apparatus 201 in response to a request from the power supply control apparatus 201, for example. The power supply information 400 includes a power input and a remaining power. The power input is information indicating whether power is supplied from the power source 213 to the uninterruptible power supply 214, for example. The remaining power may be information indicating the remaining amount of power stored in the power storage device 225. In the example of FIG. 4, the ratio of the stored power amount to the maximum stored power amount of the power storage device 225. Is shown as a percentage.

  FIG. 5 is a diagram illustrating the base information 500 according to the first embodiment. For example, the storage unit 310 may store base information 500 for each base. For example, FIG. 5A may be the base information 500 of the base 203 shown in FIG. Further, for example, FIG. 5B may be base information 500 of a base 203 different from the base 203 shown in FIG. Each entry included in the base information 500 includes information on the communication device 215 provided in the base 203 corresponding to the base information 500. The entry includes, for example, a telephone number, device priority, IP address, and device connection port, and these pieces of information are associated with each other in the entry. The telephone number is, for example, the telephone number of the communication device 215 corresponding to the entry. The device priority is, for example, the priority of the communication device 215 corresponding to the entry. The IP address is, for example, the IP address of the communication device 215 corresponding to the entry. The device connection port is information indicating the port of the PoE switch to which the communication device 215 corresponding to the entry is connected, for example. For example, the telephone number may be registered in the form of a number, and the IP address may be registered in the form of IPV4 (Internet protocol version 4).

  FIG. 6 is a diagram illustrating an operation flow of power supply control processing according to the first embodiment. For example, when an instruction to start monitoring the base 203 is input to the power supply control apparatus 201, the control unit 300 of the power supply control apparatus 201 may start the power supply control process.

  In step 601 (hereinafter, step is described as “S”, for example, expressed as S601), the control unit 300 of the power supply control device 201 acquires the input state of power from the power supply 213 to the uninterruptible power supply 214. . Note that the power supply control device 201 and the uninterruptible power supply 214 can communicate with each other via a communication line 220 as shown in FIG. And the electric power feeding control apparatus 201 may acquire information from the uninterruptible power supply 214 by TCP (Transmission Control Protocol) / IP (Internet Protocol) communication, for example. For example, the uninterruptible power supply 214 has an extended MIB (Management MIB) that specifies the status of power input from the power supply 213 to the uninterruptible power supply 214 and information indicating the capacity of the power stored in the power storage device 225. information base) may be defined in the MIB information. These extended MIBs may be added by a vendor that provides the uninterruptible power supply 214, for example. In step S <b> 601, the control unit 300 of the power supply control device 201 uses SNMP (Simple Network Management Protocol) to indicate the status of power input from the power source 213 and the capacity of the power stored in the power storage device 225. To the uninterruptible power supply 214. When the uninterruptible power supply 214 receives the request, the uninterruptible power supply 214 includes an input status of power from the power supply 213 specified by the extended MIB and information indicating the capacity of the power stored in the power storage device 225, for example, in FIG. The illustrated power supply information 400 is returned to the power supply control device 201. And the control part 300 may acquire the condition of the input of the electric power from the power supply 213 to the uninterruptible power supply 214 by referring the power supply input of the received electric power feeding information 400, for example.

  In S <b> 602, the control unit 300 determines whether or not the input of power from the power source 213 to the uninterruptible power supply 214 is stopped. For example, the control unit 300 may determine No in S602 when there is a power input of the power supply information 400 returned from the uninterruptible power supply 214. In this case, the flow returns to S601. On the other hand, when there is no power input of the power supply information 400 returned from the uninterruptible power supply 214, the control unit 300 may determine Yes in S602, and in this case, the flow proceeds to S603. The uninterruptible power supply 214 starts supplying power from the power storage device 225 to the router 211 and the PoE switch 212, for example, when input of power from the power supply 213 is stopped.

  In step S <b> 603, the control unit 300 confirms the communication status of the communication device 215. For example, the control unit 300 accesses the SIP server 202, and each of the plurality of communication devices 215 provided in the base 203 where the input of power from the power source 213 to the uninterruptible power supply 214 is stopped is busy. It is specified whether or not. Furthermore, for example, for the communication device 215 that is in a call, the control unit 300 identifies the communication device 215 that is the communication partner of the communication device 215 that is in a call.

  In S604, the control unit 300 determines a communication priority for communication during a call. For example, the control unit 300 identifies the device priority of the communication device 215 determined to be communicating in S603 and the device priority of the communication device 215 of the communication partner with reference to the base information 500. That is, for example, the control unit 300 refers to the base information 500 for the base 203 where the input of power from the power source 213 is stopped, and specifies the device priority of the communication device 215 determined to be communicating in S603. For example, the control unit 300 refers to the base information 500 of the base 203 where the communication device 215 of the communication device 215 determined to be communicating in S603 exists, and the device priority of the communication device 215 of the communication device Is identified. Then, the control unit 300 determines the communication priority from the device priority of the specified communication device 215 in communication and the device priority of the communication device 215 of the communication partner of the communication device 215.

For example, in the base information 500 of FIG. 5, the device priority is represented by high or low, and high may indicate that the device priority is high, and low may indicate that the device priority is low. Using these device priorities, the control unit 300 may determine the communication priorities as follows, for example.
Communication priority: High (The device priority of the communication device 215 and the communication device 215 of the communication partner is both high.)
Communication priority: Medium (One of the device priorities of the communication device 215 and the communication device 215 of the communication partner is high and the other is low.)
Communication priority: Low (The device priority of the communication device 215 and the communication device 215 of the communication partner is both low)

  For example, as described above, when the device priority of both of the communication device 215 and the communication device 215 of the communication partner is high, the control unit 300 increases the communication priority so that the device priority of both devices is high. The communication priority may be set so that the communication priority becomes low when the value is low.

  Subsequently, in S605, the control unit 300 determines whether or not communication is being performed for each of the plurality of communication devices 215 included in the base 203. If communication is not being performed (No in S605), the communication device is determined. The power supply to 215 is controlled by executing the process of S606. On the other hand, the control unit 300 determines whether or not communication is being performed for each of the plurality of communication devices 215 included in the base 203, and when communication is being performed (Yes in S605), The power supply is controlled by executing the process of S607.

  For example, the control unit 300 determines the supply of power from the uninterruptible power supply 214 to the communication device 215 determined not to be communicating in S606 based on the device priority of the communication device 215 acquired from the base information 500. You may control. For example, when the device priority of the communication device 215 determined not to be communicating in S606 is higher or higher, the control unit 300 may continue to supply power to the communication device 215. Further, for example, when the device priority of the communication device 215 that is determined not to be communicating in S606 is less than high (for example, low), the control unit 300 stops supplying power to the communication device 215. Good. In this case, for example, the control unit 300 outputs an instruction to the PoE switch 212 so as to shut down a port connected to the communication device 215 to be stopped. For example, the control unit 300 may specify the port to which the communication device 215 to be controlled is connected from the device connection port of the base information 500. When the process of S606 is completed, the flow returns to S601.

  In addition, for example, the control unit 300 controls the supply of power from the uninterruptible power supply 214 to the communication device 215 determined to be communicating in S607 based on the communication priority determined in S604. Good. For example, if the communication priority of the communication device 215 determined to be communicating in S607 is medium or higher, the control unit 300 may continue to supply power to the communication device 215. For example, when the communication priority of the communication device 215 determined to be communicating in S607 is less than medium (for example, low), the control unit 300 stops supplying power to the communication device 215. You may let me. In this case, for example, the control unit 300 outputs an instruction to the PoE switch 212 so as to shut down a port connected to the communication device 215 to be stopped. The control unit 300 may specify the port to which the communication device 215 to be controlled is connected from the device connection port of the base information 500. Note that when the port connected to the communication device 215 to be stopped is shut down, the PoE switch 212 may notify the communication device 215 to be stopped of information indicating that communication is to be interrupted. And the communication apparatus 215 may output the information which shows that communication is interrupted | blocked to a user, if notification is received. For example, the communication device 215 may output a voice such as “communication is cut off” as information indicating that the communication is cut off. Thereby, it is possible to prevent the user of the communication device 215 in communication from being suddenly disconnected and confused. When the process of S607 is completed, the flow returns to S601.

  In the operation flow of FIG. 6, in the processing from S <b> 601 to S <b> 604, the control unit 300 of the power supply control device 201 functions as, for example, the determination unit 301. In the processing from S605 to S607, the control unit 300 of the power supply control device 201 functions as, for example, the power supply control unit 302.

  As described above, for example, when the power supply from the power source 213 to the uninterruptible power supply 214 is stopped, the control unit 300 determines from the device priority of the communication device 215 in communication and the communication device 215 of the communication partner. Based on the determined communication priority, power supply to the communication device 215 is controlled. For example, when the communication device 215 having a low device priority is communicating with the communication device 215 of the communication partner having a high device priority, the communication priority is increased according to the device priority of the communication device 215 of the communication partner. Therefore, for example, when a communication device 215 having a low device priority is communicating with a communication device 215 of a communication partner having a high device priority, the communication that is executing communication having a low communication priority while continuing the communication. By stopping power supply to the device 215, power saving can be achieved. Further, when the communication device 215 having a low device priority is communicating with the communication device 215 of the communication partner having a high device priority, the power supply to the communication device 215 is stopped, and important communication is disconnected. Can be suppressed.

  As described above, according to the first embodiment, it is possible to determine a communication device for which it is desirable to keep the operating state from among the plurality of communication devices 215.

<Second Embodiment>
Next, the second embodiment will be described. In the first embodiment, the communication is described as an example of communication, but the embodiment is not limited to this. In the second embodiment, data transfer will be described as an example of communication. Moreover, in 2nd Embodiment, the case where the communication apparatus 215 stopped according to the fall of the electric power residual amount of the electrical storage apparatus 225 is illustrated is illustrated.

  FIG. 7 is a diagram illustrating a power supply system 700 according to the second embodiment. The power supply system 700 includes, for example, a power supply control device 201 and a base 203. In the second embodiment, since data transfer is described as an example of communication, as illustrated in FIG. 7, the power supply system 700 may not include the SIP server 202 that executes processing related to a call. The base 203 includes, for example, a router 211, a switch 712, a power supply 213, an uninterruptible power supply 214, and a plurality of communication devices 215. In the second embodiment, the uninterruptible power supply 214, for example, when power is supplied from the power supply 213, the power from the power supply 213 is supplied to the router 211, the switch 712, and the communication device 215 via the power supply line 222. Supply. Further, the uninterruptible power supply 214 may charge the power storage device 225 such as a battery provided in the uninterruptible power supply 214 with the power from the power supply 213. On the other hand, the uninterruptible power supply 214 supplies the power stored in the power storage device 225 to the router 211, the switch 712, and the communication device 215, for example, when the supply of power from the power supply 213 is stopped. The uninterruptible power supply 214 is connected to the switch 712 via the communication line 220, and notifies the power supply control apparatus 201 of information such as the power supply state from the power supply 213, for example.

  The switch 712 is connected to, for example, a plurality of communication devices 215 via the communication line 220 and mediates data transmission / reception between the router 211 and the communication device 215. For example, the switch 712 may disconnect communication of the communication device 215 by switching the switch.

  In the second embodiment, the communication device 215 may be a device having a communication function such as a personal computer (PC) or a notebook PC. Each of the plurality of communication devices 215 provided in the base 203 is connected to the uninterruptible power supply 214 via the power line 222 and receives power supply from the uninterruptible power supply 214.

  For example, in the second embodiment, the power supply control device 201 is based on the information regarding the amount of power stored in the power storage device 225, the information regarding the supply of power from the power source 213, and the communication state of the communication device 215. You may control the electric power feeding to.

  FIG. 8 is a diagram illustrating base information 800 according to the second embodiment. For example, the storage unit 310 may store base information 800 for each base. For example, FIG. 8A may be the base information 800 of the base 203 shown in FIG. Further, for example, FIG. 8B may be base information 800 for a base 203 different from the base 203 shown in FIG. Each entry included in the base information 800 includes information for the communication device 215 provided in the base 203 corresponding to the base information 800. The entry includes, for example, an IP address, a device priority, and a device connection port, and these pieces of information are associated with each other in the entry. The IP address is, for example, the IP address of the communication device 215 corresponding to the entry. The device priority is, for example, the priority of the communication device 215 corresponding to the entry. The device connection port is information indicating the port of the switch 712 to which the communication device 215 corresponding to the entry is connected, for example. For example, the IP address may be registered in the format of IPV4 (Internet protocol version 4).

  In the example of FIG. 8 according to the second embodiment, three priorities of 1, 2, and 3 are illustrated as device priorities. Here, 3 is the highest priority, and then 2 The priority is high and 1 may indicate that the priority is the lowest. In another embodiment, 3 may be the lowest priority, 2 is the lowest priority, and 1 is the highest priority.

  For example, the device priority may be set to a higher priority as the communication performed by the communication device 215 is more important. For example, in an army such as a company or the Self-Defense Force, a position may be assigned to a member who belongs to it, and a higher-ranking person may play an important role in the army such as a company or the Self-Defense Force to which he belongs. Is expensive. Therefore, for example, a higher device priority is assigned to a communication device 215 used by a member having a job title than a member having no job title, and a higher device priority is assigned to a communication device 215 used by a member having a higher job title. The device priority may be set as described above. In another example, the device priority may be set so that a higher device priority is assigned to a communication device as data transmitted through communication performed by the communication device 215 is more important. For example, an access right to important data may be given to some of the communication devices 215 provided in the base 203. For example, in such a case, the access right A higher device priority may be assigned to the communication device 215 to which is assigned.

  FIG. 9 is a diagram illustrating power supply device priority information 900 according to the second embodiment. In the power supply device priority information 900, for example, a remaining power level and a power supply device priority are registered in association with each other. For example, the remaining power may be information indicating a range of the remaining amount of power stored in the power storage device 225 of the uninterruptible power supply 214. In the example of FIG. 9, the remaining power range can be stored in the power storage device. Registered as a percentage of the maximum amount of power. In addition, the priority of the power supply device is the device priority for supplying power to the uninterruptible power supply 214 when the remaining power of the power storage device 225 is in the range indicated by the remaining power of the power supply device priority information 900. This is information indicating the degree. In the power supply device priority of the power supply device priority information 900, a device priority equal to or higher than a predetermined priority is registered according to the remaining power.

  FIG. 10 is a diagram illustrating power supply communication priority information 1000 according to the second embodiment. In the power supply communication priority information 1000, for example, the remaining power and the power supply communication priority are registered in association with each other. For example, the remaining power may be information indicating the range of the remaining amount of power stored in the power storage device 225 of the uninterruptible power supply 214. In the example of FIG. The percentage of the large amount is registered in the remaining power. The power supply communication priority is information indicating a communication priority for which the uninterruptible power supply 214 is to be supplied with power when the remaining power of the power storage device 225 is in the range indicated by the remaining power. In the power supply communication priority of the power supply communication priority information 1000, a communication priority equal to or higher than a predetermined priority is registered according to the remaining power.

  FIG. 11 is a diagram illustrating an operation flow of power supply control processing according to the second embodiment. For example, when an instruction to start monitoring the base 203 is input to the power supply control apparatus 201, the power supply control process may be started.

  In step S <b> 1101, the control unit 300 of the power supply control device 201 acquires an input state of power from the power source 213 to the uninterruptible power supply 214. For example, the control unit 300 may acquire the power input state from the power supply 213 to the uninterruptible power supply 214 by executing the same processing as in S601 described above.

  In S1102, the control unit 300 determines whether or not input of power from the power source 213 to the uninterruptible power supply 214 is stopped. For example, as described in S602, the control unit 300 may determine whether or not power input is stopped based on the power supply information 400 received from the uninterruptible power supply 214. When power is input from the power source 213 to the uninterruptible power supply 214 (No in S1102), the flow returns to S1101. On the other hand, when there is no input of power from the power source 213 to the uninterruptible power supply 214 (S1102 is Yes), the flow proceeds to S1103. The uninterruptible power supply 214 starts supplying power from the power storage device 225 to the router 211, the switch 712, and the communication device 215, for example, when input of power from the power supply 213 is stopped.

  In step S1103, the control unit 300 confirms the communication status of the communication device 215. For example, the control unit 300 requests notification of the communication status from the plurality of communication devices 215 included in the base 203 using SNMP. Upon receiving the request, the communication device 215 receives information indicating whether or not communication is being performed, and information indicating the communication partner (for example, the IP address of the communication device 215 of the communication partner) when the communication is in progress. 201 is notified. Then, based on the notified information, the control unit 300 determines whether or not each of the plurality of communication devices 215 in the base 203 where the supply of power from the power source 213 is stopped is in communication. If there is, the communication device 215 of the communication partner is specified. In the second embodiment, for example, the communicating communication device 215 may execute communication for transmitting data to another communication device 215.

  In S1104, the control unit 300 determines the communication priority of communication during communication. For example, the control unit 300 specifies the device priority of the communication device 215 in communication identified in S1103 and the device priority of the communication device 215 of the communication partner with reference to the base information 800. That is, for example, the control unit 300 refers to the base information 800 for the base 203 where the input of power from the power source 213 is stopped, and specifies the device priority of the communication device 215 that is in communication. For example, the control unit 300 refers to the base information 800 of the base 203 where the communication device 215 of the communication partner of the communication device 215 in communication exists, and identifies the device priority of the communication device 215 of the communication partner. Then, the control unit 300 determines the communication priority from the combination of the specified device priority of the communication device 215 in communication and the device priority of the communication device 215 of the communication partner of the communication device 215. For example, in the base information 800 of FIG. 8, the device priority is represented by 1, 2, and 3, with 3 being the highest device priority, 2 being the highest device priority, and 1 being the device priority. May indicate the lowest.

In one example, the control unit 300 may determine the communication priority as follows.
Communication priority: 2 (The device priority of the communication device 215 and the communication device 215 of the communication partner are both 1)
Communication priority: 3 (one of the device priorities of the communication device 215 and the communication device 215 of the communication partner is 1 and the other is 2)
Communication priority: 4 (both the device priority of the communication device 215 and the communication device 215 of the communication partner is 2, or one of the device priority of the communication device 215 and the communication device 215 of the communication partner is 1, The other is 3.)
Communication priority: 5 (one of the device priorities of the communication device 215 and the communication device 215 of the communication partner is 2 and the other is 3)
Communication priority: 6 (both the device priority of the communication device 215 and the communication device 215 of the communication partner is 3)

  For example, as described above, when the device priority of both of the communication device 215 and the communication device 215 of the communication partner is high, the control unit 300 increases the communication priority so that the device priority of both devices is high. The communication priority may be determined so that the communication priority becomes low when the value is low. The communication priority may be calculated, for example, by adding one device priority of the communication device 215 in communication and the other device priority. For example, if one device priority of the communication device 215 in communication is 1 and the other device priority is 1, 1 + 1 = 2 and the communication priority may be 2. Similarly, if one device priority of the communication device 215 in communication is 1 and the other device priority is 2, 1 + 2 = 3 and the communication priority may be 3. If one device priority of the communication device 215 in communication is 1 and the other device priority is 3, 1 + 3 = 4 and the communication priority may be 4. If one device priority of the communication device 215 in communication is 2 and the other device priority is 2, 2 + 2 = 4 and the communication priority may be 4. If one device priority of the communication device 215 in communication is 2 and the other device priority is 3, 2 + 3 = 5 and the communication priority may be 5. If one device priority of the communication device 215 in communication is 3 and the other device priority is 3, 3 + 3 = 6 and the communication priority may be 6.

  Here, among communication priorities: 2 to 6, communication priority: 2 is assigned the lowest communication priority, and communication priority: 6 is assigned the highest communication priority. The case is illustrated. However, in another embodiment, for example, the highest communication priority may be assigned to communication priority: 2, and the lowest communication priority may be assigned to communication priority: 6.

  Subsequently, in S1105, the control unit 300 determines whether or not communication is being performed for each of the plurality of communication devices 215 included in the base 203. If communication is not being performed (No in S1105), the control unit 300 determines whether the communication device 215 is connected. The power supply is controlled by executing the process of S1106. On the other hand, the control unit 300 determines whether each of the plurality of communication devices 215 included in the base 203 is communicating, and when the communication is being performed (Yes in S1105), supplies power to the communication device 215. Is controlled by executing the processing of S1107.

  For example, in S1106, the control unit 300 determines the supply of power from the uninterruptible power supply 214 to the communication device 215 that is determined not to be in communication, the device priority of the communication device 215 acquired from the base information 800, and no You may control based on the electric power residual amount of the power failure power supply 214. FIG. For example, the control unit 300 identifies the power supply device priority from the entry of the power supply device priority information 900 corresponding to the remaining power of the uninterruptible power supply 214. That is, for example, it is assumed that the remaining power of the uninterruptible power supply 214 acquired in S1101 is 13%. In this case, the control unit 300 has two or more priorities (for example, 2, 2) included in the power supply device priority of the entry of the power supply device priority information 900 including 13% in the range: 25 to 11%. 3) is specified. Then, when the device priority of the communication device 215 determined not to be in communication is two or more specified priorities, the control unit 300 is uninterrupted so as to continue supplying power to the communication device 215. An instruction is transmitted to the power supply device 214. On the other hand, in S1106, when the device priority of the communication device 215 determined not to be communicating is not a priority of 2 or higher but a priority lower than 2, the control unit 300 proceeds to the communication device 215. An instruction is transmitted to the uninterruptible power supply 214 to stop the supply of power. When the control unit 300 executes control of power supply to the communication device 215 in S1106, the flow returns to S1101.

  In S1107, the control unit 300 determines the supply of power from the uninterruptible power supply 214 to the communication device 215 determined to be in communication, for example, the communication priority determined in S1104, and the uninterruptible power supply. Control may be performed based on the remaining power of 214. For example, the control unit 300 identifies the power supply communication priority from the entry of the power supply communication priority information 1000 corresponding to the remaining power of the uninterruptible power supply 214. That is, for example, it is assumed that the remaining power of the uninterruptible power supply 214 acquired in S1101 is 30%. In this case, the control unit 300 has four or more priorities (for example, 4, 4) included in the power supply communication priority of the entry of power remaining in the power supply communication priority information 1000 including 30% in the range: 50 to 26%. 5 and 6) are specified. In S1107, if the communication priority of the communication device 215 determined to be in communication is 4 or higher, the control unit 300 does not maintain power supply to the communication device 215. An instruction is transmitted to the power failure power supply 214. On the other hand, in step S <b> 1107, the control unit 300 determines that the communication priority of the communication device 215 that is determined to be communicating is not the specified priority of 4 or higher, but is lower than 4, the communication device 215 An instruction is transmitted to the uninterruptible power supply 214 so as to stop the power supply. When the control unit 300 executes control of power supply to the communication device 215 determined to be communicating in S1107, the flow returns to S1101.

  In the operation flow of FIG. 11, in the processing from S <b> 1101 to S <b> 1104, the control unit 300 of the power supply control device 201 functions as the determination unit 301, for example. In the processing from S1105 to S1107, the control unit 300 of the power supply control apparatus 201 functions as, for example, the power supply control unit 302.

  As described above, in the second embodiment, the control unit 300 of the power supply control device 201 has the device priority of the communication device 215 in communication when the power supply from the power source 213 to the uninterruptible power supply 214 is stopped. Then, the communication priority is determined from the device priority of the communication device 215 of the communication partner. Then, power supply to the communication device 215 is controlled based on the determined communication priority and the remaining power level notified from the uninterruptible power supply 214. Therefore, the second embodiment has the same effect as the first embodiment, and controls the power supply to the communication device 215 step by step according to the remaining power stored in the power storage device 225. Is possible. For example, when the remaining amount of power stored in the power storage device 225 is sufficient, the user is less affected by the stop of power supply from the power source 213 by reducing the number of communication devices 215 to be stopped. Thus, the communication device 215 can be used. On the other hand, for example, in a situation where the remaining amount of power stored in the power storage device 225 has decreased, for example, by reducing the number of communication devices 215 operating according to the communication priority, the uninterruptible power supply device Power consumption stored in 214 can be reduced. As a result, for example, the communication device 215 performing important communication with a high communication priority can be maintained for a longer period of time.

  In the above, some embodiments have been illustrated, but the embodiments are not limited thereto. For example, the above-described operation flow is an example, and the embodiment is not limited to this. If possible, the operation flow may be executed by changing the order of processing, may include additional processing, or some processing may be omitted.

  For example, in the above-described embodiment, when power supply from the power source 213 to the uninterruptible power supply 214 is stopped at a certain site 203, the communication device 215 in the site 203 communicates with a plurality of other communication devices 215. May have. In such a case, for example, the control unit 300 of the power supply control apparatus 201 uses the device priority of two communication devices 215 having a higher device priority among the three or more communication devices 215 in communication. The priority may be determined and the power supply to the communication device 215 may be controlled.

  Alternatively, in another embodiment, when power supply from the power source 213 to the uninterruptible power supply 214 is stopped at a certain site 203, the communication device 215 in the site 203 communicates with other communication devices 215. Suppose that In this case, the communication may be an important communication that affects a large number of people. Therefore, the control unit 300 may determine a higher communication priority for communication by three or more communication devices 215 than in the case of one-to-one communication device 215 communication. That is, for example, when power supply from the power supply 213 to the uninterruptible power supply 214 is stopped at a certain base 203, the communication equipment 215 in the base 203 is communicating with a plurality of other communication equipment 215. . In this case, in S1104, the control unit 300 determines the communication priority using the device priority of the two communication devices 215 having the higher device priority among the three or more communication devices 215 in the communication, and further determines The assigned communication priority may be changed to one higher priority. For example, when the communication priority determined using the device priority of two communication devices 215 having a higher device priority among the three or more communication devices 215 that are communicating in S1104 is 3, the control unit 300 The communication priority may be changed to one higher communication priority: 4. Alternatively, in yet another embodiment, the entry of the base information 800 may include a device priority when the communication device 215 is communicating with other communication devices 215. Then, when the communication device 215 communicates with a plurality of other communication devices 215, the control unit 300 performs communication using the device priority when the communication device 215 communicates with the other plurality of communication devices 215. Priorities may be determined. In the base information 800, the device priority when communicating with a plurality of other communication devices 215 is set to a higher value than the device priority when the communication device 215 performs one-to-one communication. May have been.

  Further, for example, in the first embodiment, power is supplied from the PoE switch via the Ethernet (registered trademark) wiring 223. For example, communication and power supply can be implemented with a single wiring by supplying power with PoE as exemplified in the first embodiment. Therefore, it is not necessary to separately install equipment and wiring for supplying power, the cost of the entire power feeding system 200 can be suppressed, and the danger caused by complicated wiring can be avoided. .

  In the above-described embodiment, when the supply of power from the power source 213 to the uninterruptible power supply 214 is stopped, for example, it may be when a power failure occurs. Moreover, in the above-mentioned embodiment, the case where supply of the electric power from the power supply 213 to the uninterruptible power supply 214 is stopped is illustrated as a situation where the electric power stored in the power storage device 225 of the uninterruptible power supply 214 is used. Yes. However, the embodiment is not limited to this. For example, when the power supplied from the power source 213 to the uninterruptible power supply 214 is limited (for example, when a peak cut request is received), the above-mentioned is performed to reduce the power supplied to the communication device 215. The embodiments may be applied.
