It is a network structure figure of the present invention. It is explanatory drawing of a structure of the management apparatus of this invention. It is a structure figure of the internal network comprised by the object computer. It is a network structure figure at the time of the initial setting of this invention. FIG. 3 is a structural diagram of a network during remote power management of the present invention. It is a sequence diagram of the present invention. It is a sequence diagram of an embodiment of the present invention to which identification information is applied.

  Hereinafter, the configuration and execution process of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a network structure diagram showing the entire components that are operated step by step in the execution process of the present invention.

  As shown in the figure, the present invention includes a connection device such as a router 10 for connecting an internal network and an external network, a large number of target computers 11 constituting the internal network, a management device 20 directly connected to the internal network, and The setting computer 21, the Internet as an external network, that is, a management server 30 connected to the external Internet, a management database 31 connected to the management server 30, and a control computer 41 connected to the management server 30 via the Internet And executed by.

  In the present invention, the internal network is a communication network constructed by being connected via a network connection device such as a common router 10 and a shared machine. For example, a large number of computers are directly connected to a single router 10, that is, A fixed IP in-house network or the like directly connected is applicable. On the other hand, the external network is the external Internet which is an external communication network connected to the internal network.

  The components of the internal network directly connected to the single router 10 include, in addition to the target computer 11 shown in FIG. 1, a server for internal network management indicated by a virtual line in FIG. 1, a network printer (not shown), etc. Peripheral devices.

  As shown in FIG. 1, when performing remote power management of a computer according to the present invention, a management device 20 directly connected to an internal network includes a central processing unit (CPU), a storage device, and a network as shown in FIG. Consists of an adapter.

  The network adapter attached to each component of the internal network such as the target computer 11 and the management device 20 is hardware including a network interface card or a LAN card, and forms a physical hierarchy of the internal network. In addition, since it is necessary to start the target computer 11 that is turned off or to end the target computer 11 that is turned on based on the management signal, as a network adapter attached to the target computer 11, It is necessary to use one that is compatible with WOL.

  On the other hand, the network adapter attached to the management apparatus 20 does not necessarily have to be compatible with WOL. This is because in the present invention, the management device 20 is always connected to the power source and activated while being directly connected to the router 10, that is, the internal network.

  As is clear from the structure of the management apparatus 20 of the present invention shown in FIG. 2, the management apparatus 20 of the present invention is an information device capable of performing network communication, and includes a storage device, and records and retrieves information. In addition to the main components shown in the figure, the information device includes a power supply unit for operating these components, a board, and the like.

  That is, in the present invention, the management device 20 directly connected to the internal network does not need to have the same functions as a normal computer such as activation of various application programs and execution of input / output, but from the viewpoint of network communication, It does not have its own human interface and has the same functions as a normal computer.

  When the setting computer 21 connects the management device 20 to the internal network for the first time, the setting computer 21 calls, activates, and controls the management device 20, provides a human interface that the management device 20 does not provide, and operates the setting computer 21. The user can access the management device 20 and confirm the required information. As the setting computer 21, a computer with a normal network adapter can be used, and a program for communicating with the management apparatus 20 is installed. Note that the operator of the setting computer 21 may be a user of the control computer 41.

  In the present invention, the setting computer 21 is used only when the management apparatus 20 is first connected to the internal network. Therefore, after the management apparatus 20 is connected to the internal network, the connection between the setting computer 21 and the internal network is performed. May be cut.

  Thus, the internal network constructed by a large number of target computers 11, management devices 20, etc. connected to a single router 10 is connected to the external network. In the present invention, the external network represents the external Internet excluding the internal network. In the broad sense, an internal network is also included in the Internet. Therefore, in the present invention, an internal computer communication network connected to a single router 10 is referred to as an internal network, and an external Internet to which the internal network is connected via the router 10 is referred to. This is called an external network.

  FIG. 3 shows a configuration of the internal network before the remote power management of the computer of the present invention. A large number of target computers 11 are directly connected to a connection device such as the router 10 and connected to the external Internet.

  In the present invention, as shown in FIG. 4, the management device 20 and the setting computer 21 are directly connected to the internal network, and the internal network is connected to the management server 30 via the external Internet. It is connected to the database 31. Note that until the management computer 20 is activated by the setting computer 21, no substantial communication is performed between the management computer 30 and the target computer 11 constituting the internal network.

  The management server 30 connected to the external network receives and manages connection information (identification information in the example of FIG. 7) to be described later, and forwards the connection information to the management device 20 in response to a request from the control computer 41. For this purpose, as shown in FIGS. 1, 4 and 5, connection information is managed by connecting to the management database 31. In FIGS. 1, 4 and 5, the management database 31 and the management server 30 are shown as separate bodies, but the management database 31 can be arranged in the storage device of the management server 30.

  As described above, the present invention executed by the target computer 11 and the management device 20 for constructing the internal network and the management server 30 connected to the external network, the management device 20 and the setting computer 21 are directly connected to the internal network. In this state, as shown in FIG. 6, the setting computer 21 starts with a step of sending call information including the network adapter MAC address of itself (setting computer 21) to the internal network using the broadcast method.

  That is, a program installed in the setting computer 21 is activated in a state where the management device 20 and the setting computer 21 connected to the power source are directly connected to a connection device such as the router 10 that constructs the internal network. Call information including the network adapter MAC address is sent to an unspecified number of network adapters in the internal network using a broadcast method.

  Next, the management device 20 receives the call information and transfers the device information including its own network adapter MAC address to the setting computer 21 to respond. At this time, the target computer 11 in the internal network ignores the call information transmitted using the broadcast method, but the storage device of the management device 20 has a program for receiving and processing the call information. The management apparatus 20 extracts the network adapter MAC address of the setting computer 21 from the received call information, and transfers a response signal via the network adapter MAC address.

  That is, after receiving the network adapter MAC address of the setting computer 21 that is first broadcast by the setting computer 21, the management device 20 receives device information including the network adapter MAC address of itself (the management device 20) of the setting computer 21. Transfer to the network adapter MAC address using the unicast method. As a result, a one-to-one communication path is established between the setting computer 21 and the management device 20, and a human interface necessary for an operator to operate the management device 20 is provided by the setting computer 21. The operator of the management device 20 may be a user of the control computer 41.

  Through the process described above, the operator can grasp the connection of the internal network of the management apparatus 20 and the presence or absence of normal operation via an output device such as a monitor of the setting computer 21. Subsequently, when the operator operates the setting computer 21 or the installation program of the setting computer 21 in which the operator confirms the connection and normal operation of the internal network of the management device 20 automatically operates, the management device 20 Is activated in order to acquire connection information of the target computer 11 in the internal network.

  That is, the setting computer 21 receives device information from the management device 20 and transfers an activation signal to the management device 20. At this time, the activation signal transferred to the management device 20 takes a control command format such as a character string that can be processed by a program installed in the management device 20.

  When the activation signal is transferred from the setting computer 21 to the management device 20, a step is performed in which the management device 20 sends search information including its own network adapter MAC address to the internal network using a broadcast method.

  The search information transmitted by the management apparatus 20 to the unspecified target computer 11 in the internal network using the broadcast method includes the network adapter MAC address of the management apparatus 20 and the search information is the received target computer. 11 is sent in expectation of a response from 11. The present invention assumes a situation in which no special function is added to the network adapter of the target computer 11 in addition to the normal WOL function. In the broadcast method used for sending search information, It is preferable to protect an address resolution protocol (ARP) that is a kind of standard protocol.

  When the management apparatus 20 sends search information using the broadcast method, each target computer 11 receives the search information and transfers connection information including its own network adapter MAC address to the management apparatus 20.

  That is, each target computer 11 that has received the search information transfers connection information including the network adapter MAC address of itself (target computer 11) to the network adapter MAC address of the management apparatus 20 using the unicast method. Then, the management apparatus 20 acquires connection information such as the network adapter MAC address necessary for driving the WOL of the network adapter of the target computer 11.

  Thereby, the user of the control computer 41 recognizes each connection information of the target computer 11 and acquires the connection information of the target computer 11 in the internal network without performing an operation such as inputting to the control computer 41. The acquired connection information can be temporarily or permanently recorded in the storage device of the management device 20 and transferred to the management server 30 in the external network, or thereafter in response to a request from the management server 30 It is taken out and used when driving the WOL of the target computer 11.

  Then, the management apparatus 20 that has received the connection information of the target computer 11 through the above-described process, transferred the connection information to the management server 30 via the Internet, which is an external network, and received the connection information. The server 30 records the connection information in the management database 31.

  Here, the management server 30 is operated by a company that manufactures or sells the management apparatus 20, a communication company, an Internet information provider company, or the like, and is installed between the management apparatus 20 and the management server 30 by a program installed in the management apparatus 20. Are established and operated quickly and stably.

  For example, when the management server 30 is operated by a company that manufactures or sells the management device 20, when the management device 20 is manufactured, a program in which items necessary for connection with the management server 30 are set is managed by the management device 20. Therefore, it is possible to stably establish a communication path between the management device 20 and the management server 30 without performing any special operation by the operator. The information can be smoothly transferred to the management server 30 or the control signal can be transferred to the management device 20 by the management server 30 smoothly.

  In particular, in the present invention, the management apparatus 20 is always started by being connected to a power source, the management apparatus 20 and the management server 30 function as a client and a server, respectively, and the management apparatus 20 accesses the management server 30. However, even if a firewall is constructed between the internal network and the external network, communication can be performed smoothly.

  FIG. 5 shows a state in which the connection information of the target computer 11 is recorded in the management database 31 through the process described above, and the remote control computer 41 performs power management of the target computer 11 via the Internet to the management server 30. The network configuration in the process of performing the step of requesting and receiving the request from the management server 30 that extracts the connection information of the target computer 11 from the management database 31 and transfers it to the management apparatus 20 is shown. As shown in the figure, the connection between the setting computer 21 and the internal network, which were directly connected to the internal network, can be disconnected.

  As described above, the remote power management of the target computer 11 is to terminate the target computer 11 that is turned on or start the target computer 11 that is turned off. As shown, the remote control computer 41 requests the management server 30 for remote power management of the target computer 11 via the Internet, and the management server 30 that receives the request sends the connection information of the target computer 11 to the management database 31. And is transferred to the management apparatus 20 and the management apparatus 20 that has received the connection information transfers a management signal to the target computer 11.

  The management signal is a signal for driving a network adapter capable of supporting WOL, and when the management signal is received, the network adapter capable of supporting WOL activates or terminates the target computer 11.

  As shown in FIG. 5, the communication between the control computer 41 and the management server 30 constructs a web page 35 operated by the management server 30, and a browser mounted on the control computer 41 is added to the web page 35. This is done according to the connection method. Thereby, since it is not necessary to install a special dedicated program in the control computer 41, it is possible not only to efficiently communicate between the management server 30 and the control computer 41, but also in general that does not have a high level of expertise. An interface that can be used by a user can be provided.

  In the process in which the control computer 41 connects to the management server 30 and requests the management server 30 to perform remote power management of the target computer 11, confirmation of the user's eligibility in the control computer 41, that is, user authentication, And a normal authentication method such as inputting a password.

  As described above, when the management server 30 is operated by a company that manufactures or sells the management device 20, the operator (purchaser) gives each management device 20 acquired when the management device 20 is purchased. The unique information such as the ID and the password or the serial number is notified to the user of the control computer 41 in advance, and the user of the control computer 41 is notified when the management apparatus 20 is connected to the management server 30. Is entered into the web page 35 or the like to authenticate the user.

  In the sequence of FIG. 7, the management apparatus 20 transfers identification information corresponding to the connection information to the management server 30 instead of the connection information of the target computer 11. Thereby, it is possible to prevent the connection information including the network adapter MAC address of the target computer 11 from leaking to the external network. As a result, unauthorized access to the target computer 11 via connection information can be prevented, and security can be improved.

  In the embodiment to which the identification information shown in FIG. 7 is applied, the setting computer 21 stores the call information including its own network adapter MAC address as in the embodiment shown in FIG. Each process from the step of sending to the network using the broadcast method to the step of the target computer 11 receiving the search information of the management device 20 and transferring the connection information including its own network adapter MAC address to the management device 20 Done.

  In the embodiment shown in FIG. 6, the connection information sent from the target computer 11 to the management apparatus 20 is transferred to the management server 30 of the external network, whereas in the embodiment shown in FIG. When the connection information is transferred from the target computer 11 to the management device 20, identification information corresponding to the connection information is generated in the management device 20, and the identification information is transferred to the management server 30 of the external network.

  In the embodiment in which the identification information is applied, as shown in FIG. 7, when the target computer 11 performs the step of transferring the connection information to the management device 20, the management device 20 displays the received connection information. Recorded in the storage device of the management device 20, generates identification information corresponding to the connection information, transfers the identification information to the management server 30 via the Internet, which is an external network, and the management server 30 manages the received identification information A step of recording in the database 31 is performed.

  The identification information is generated in a one-to-one correspondence with the connection information of the target computer 11 by a program installed in the management apparatus 20, and then the management server 30 performs remote power management of the target computer 11 from the control computer 41. When the request is received, the information becomes information for identifying the target computer 11.

  The control computer 41 requests remote power management of the target computer 11 via the Internet, and the management server 30 that receives the request extracts the identification information of the target computer 11 from the management database 31 and transfers it to the management device 20. Then, the management device 20 that has received the identification information takes out the connection information corresponding to the identification information from its own storage device and transfers the management signal to the target computer 11 based on the connection information. As a result, the power supply of the target computer 11 can be managed remotely without leakage of connection information to the external network.
