[Embodiment 1]
FIG. 1 is a diagram schematically illustrating a configuration of an electronic system according to the first embodiment. In FIG. 1, an electronic system 10 is, for example, an information processing device such as a personal computer or a server, various electronic control devices, or the like. The electronic system 10 includes a casing 11 that constitutes the electronic system 10, and the casing 11 includes a configuration unit 12, a lock unit 13, a wireless key receiver 14, a touch sensor 15, a control unit 16, and an alarm transmitter 17. .

  The configuration unit 12 is a maintenance target component such as a blade, a disk, a board, or a memory, and is detachably mounted on the housing 11. Although FIG. 1 shows a case where there is only one component unit 12, it is usual that a plurality of units are actually mounted.

  The lock unit 13 has a function of fixing the corresponding component unit 12 to the housing, and can release the lock mechanism by a control signal from the control unit 16. The lock unit 13 is composed of an actuator such as an air cylinder or a solenoid (electromagnet), for example, so that the lock unit 13 cannot be removed mechanically. A unit that inserts and locks a cylinder or solenoid rod may be used. The lock unit 13 may release (unlock) the lock mechanism with a solenoid (electromagnet) with a built-in spring, for example. For example, it may be locked with a self-returning solenoid having a built-in spring, unlocked, or locked / unlocked by rotating the servo motor or pulse motor forward / reversely.

  The wireless key receiving unit 14 detects that an activated wireless key (not shown) has approached and outputs an access key of the wireless key to the control unit 16. The wireless key generates a predetermined signal using light such as radio waves, near infrared rays, magnetic induction, and sound waves. Since the wireless key requires security, the wireless key transmits a radio wave having a receivable intensity within a predetermined communication area (for example, 70 to 100 cm), and the wireless key and the wireless key receiving unit 14 are transmitted only within the range. A comparison may be made between them.

  The touch sensor 15 is arranged for each corresponding configuration unit 12 and outputs a message to that effect to the control unit 16 when it senses contact or proximity of a human body. The touch sensor 15 may be installed in the configuration unit 12. The touch sensor 15 may be, for example, a capacitance-type proximity sensor, an optical sensor that detects a distance, and the like.

  The control unit 16 authenticates the access key output from the wireless key receiving unit 14, and then, when the touch sensor 15 detects the contact or proximity of a human body such as a maintenance person, the control unit 16 performs the procedure of the electronic system 10 according to a predetermined procedure. The control unit 16 performs control so that the lock unit 13 corresponding to the touch sensor 15 is released. The control unit 16 may realize such a function by causing a built-in computer to execute a program.

  The alarm transmission unit 17 is activated by the control unit 16 when the touch sensor 15 senses the proximity of a human body without the control unit 16 authenticating the access key, and issues an alarm such as sound or light. The alarm transmitter 17 may be a built-in sound board, for example.

  Next, the operation of the electronic system 10 having the above configuration will be described. FIG. 2 is a flowchart showing the operation of the electronic system 10.

  In step S1, if the lock unit 13 is not in the locked state, the process is terminated. If the lock unit 13 is in the locked state, the process proceeds to step S2.

  In step S2, the wireless key transmits a predetermined signal (access key) including an ID (Identification) or authentication key signal.

  In step S3, the wireless key receiving unit 14 receives an ID or authentication key signal issued by the wireless key.

  In step S4, the control unit 16 authenticates the access key output from the wireless key receiver 14 by comparing it with an authentication key registered in advance.

  In step S5, the control unit 16 ends the process if the access key does not match the authentication key, and proceeds to step S6 if the access key matches the authentication key.

  In step S6, the control unit 16 sets the lock unit 13 in a standby state so that the lock unit 13 can be opened.

  In step S7, the touch sensor 15 detects contact or proximity of a human body. That is, when the maintenance person tries to remove the parts of the maintenance target device, the touch sensor 15 detects the maintenance person's hand.

  In step S8, the control unit 16 executes the shutdown of the electronic system 10 according to a predetermined procedure.

  In step S9, the control unit 16 opens the lock unit 13 and ends the series of processes.

  According to the electronic system 10 that operates as described above, access key authentication and touch sensor sensing can be used together to unlock the desired maintenance target component unit. Therefore, the person in charge of maintenance mistakes the device to be maintained and removes the parts of the IT (information technology) device (server device, personal computer, etc.) that is operating, causing a failure in the IT device. There is no such thing.

  In addition, although it is a maintenance target device, it does not cause a failure because a maintenance person removes a part or the like during operation even though it is not shut down.

  Further, the control unit 16 performs shutdown while grasping the operating state of the apparatus to be maintained, and thereafter the maintenance staff can remove the parts and the like, so that the work time does not become longer than necessary.

  Further, in the electronic system 10 according to the present embodiment, the person in charge of maintenance does not have the wireless key or the like, or has the wireless key outside the maintenance target device to unlock the maintenance target device, and The cover or the like cannot be unlocked so that the parts in the device can be exchanged. Therefore, the electronic system 10 according to the present embodiment can prevent parts from being removed or exchanged by outside parties, and parts from being stolen. At this time, the electronic system 10 according to the present embodiment can generate a buzzer sound by the alarm transmission unit 17 such as a built-in sound board, thereby giving a theft prevention warning or notifying the maintenance target device of error prevention.

  The electronic system 10 according to the present embodiment contributes to preventing a failure caused by removing the constituent unit 12 to be maintained while the electronic system 10 is in operation. In addition, the electronic system 10 according to the present embodiment contributes to reducing the time for confirming the procedure for bringing down the electronic system 10.

[Embodiment 2]
FIG. 3 is a diagram schematically illustrating a configuration of an electronic system according to the second embodiment. In FIG. 3, the electronic system 20 includes a desktop PC 21a, a server device 21b, and a control device 26. The control device 26 and each of the desktop PC 21a and the server device 21b, which are information processing devices, are connected via a network.

  The desktop PC 21a corresponds to the electronic system 10 described in the first embodiment. However, the control unit 16 in FIG. 1 is a device connected as a control device 26 via a network. The desktop PC 21a has a lock unit 23a corresponding to the lock unit 13 in FIG. 1 and a touch sensor 25a corresponding to the touch sensor 15 in FIG. 1, and a wireless key receiving device 24a corresponding to the wireless key receiving unit 14 in FIG. It is arranged near or inside the desktop PC 21a.

  When the wireless key receiving device 24a receives a specific signal transmitted from the wireless key 30, the wireless key receiving device 24a notifies the control device 26 accordingly. In this case, the signal transmitted by the wireless key 30 includes information for specifying the desktop PC 21a.

  The server device 21b corresponds to the electronic system 10 described in the first embodiment, and is connected to the control device 26 via a network. The server device 21b includes a lock unit 23b corresponding to the lock unit 13 in FIG. 1 and a touch sensor 25b corresponding to the touch sensor 15 in FIG. 1, and a wireless key receiving device 24b corresponding to the wireless key receiving unit 14 in FIG. Is arranged near or inside the server device 21b.

  When the wireless key receiving device 24b receives a specific signal transmitted from the wireless key 30, the wireless key receiving device 24b notifies the control device 26 accordingly. In this case, the signal transmitted by the wireless key 30 includes information for specifying the server device 21b.

  In FIG. 3, the lock units 23a and 23b, the touch sensors 25a and 25b, and the wireless key receiving devices 24a and 24b are illustrated as being directly connected to the control device 26 via a network. However, this means only a logical connection, and in practice it is usually physically connected via the desktop PC 21a or the server device 21b.

  Next, the control device 26 will be described. FIG. 4 is a block diagram showing the configuration of the control device 26. The control device 26 includes an authentication unit 27, an information input unit 28, and a lock control unit 29.

  The authentication unit 27 authenticates the access key input from the wireless key receiving devices 24a and 24b.

  The information input unit 28 receives information indicating that the proximity of the human body to the touch sensors 25a and 25b is detected.

  When the information input unit 28 receives information that the proximity of the human body is sensed after the authentication unit 27 authenticates the access key, the lock control unit 29 causes the desktop PC 21a or the server device 21b that is the target of authentication and proximity to fall. Is executed, the lock units 23a and 23b are controlled to be released.

  Here, regarding the shutdown, the control device 26 may perform a shutdown or the like remotely from a maintenance target device or system, or may transmit a shutdown command. Alternatively, the maintenance target device may be a local computer or a remote computer, and a command for instructing shutdown may be transmitted. Further, a tool for performing shutdown may be installed in a personal computer or server device connected to a LAN (Local Area Network).

  In addition, the control device 26 may determine that the maintenance target device has fallen (shut down) from the time when a predetermined time has passed since the shutdown instruction or the shutdown processing instruction. In addition, the control device 26 outputs a signal from a separate device that issues a signal indicating that the signal output from the maintenance target device is no longer output, the voltage is lower than the predetermined voltage, or the shutdown is completed. It may be determined that the maintenance target device has fallen by receiving it.

  When the control device 26 determines that the maintenance target device has fallen, the control device 26 releases the lock that is mechanically locked so that the circuit board, components, and the like in the maintenance target device cannot be removed.

  Also in the electronic system 20 according to the present embodiment, the desktop PC 21a or the server device 21b and the control device 26 operate in the same manner as the electronic system 10 according to the first embodiment, and a failure occurs as in the first embodiment. It is possible to reduce the time required for prevention and procedure confirmation. When a plurality of information processing apparatuses are synchronized in synchronization, the information processing apparatus must be turned off and shut down in a predetermined order. In this case, even if the maintenance person does not know the shutdown method, the control device 26 shuts down each information processing apparatus by a predetermined method, so that a long time is not required for the maintenance person. That is, the control device 26 automatically recognizes the connection of the information processing device and controls the shutdown order of the information processing devices determined in advance according to the connection of the information processing device, thereby enabling the shutdown.

  Furthermore, since the control device 26 centrally controls a plurality of information processing devices (desktop PC 21a and server device 21b) connected via a network, the redundancy in the system configuration is reduced in a large-scale system. The
