  EMBODIMENT OF THE INVENTION The form (Example) for implementing this invention is demonstrated below using drawing.

  Hereinafter, details of the configuration and method of the computer according to the present invention will be described in detail.

  FIG. 1 shows the configuration of an electronic computer related to this embodiment. The electronic computer 100 includes a central processing unit 110 (hereinafter referred to as a CPU), a main memory 111, an I / O controller 112 (Input Output: input / output control device), a disk device 113, and an expansion bus 121. An I / O controller 112 is connected to the CPU 110, and a disk device 113, a power supply control circuit 119, and an expansion bus 121 are connected via the I / O controller 112. A circuit for expanding the functions of the electronic computer 100 is connected to the expansion bus 121.

  In general, the insertion board 200 on which a circuit is mounted is connected to the expansion bus 121 in a form of being inserted into a connector. This insertion board may be anything, such as a graphic card, a sound card, a network card, a RAID card, a fiber channel card, or the like that exchanges information with the CPU and expands the CPU function.

  Further, an insertion board monitoring device 202 is installed near both ends of the connector of the insertion board. The CPU 110 is connected to the disk device 113, the power supply control circuit 119, and the expansion bus 121 via the I / O controller 112, and is further connected to the insertion board 200 (200a to 200c) via the expansion bus 121. The CPU 110 is also connected to the insertion board monitoring device 202. The CPU 110 operates according to software 117 read from the disk device 113 into the main memory 111. FIG. 2 is an example of the insertion board monitoring apparatus 202. In FIG. 2, a switch (a contact 203) and a switch (b contact 204) are installed near both ends of the connector 201, and the insertion board 200 is informationally connected to the CPU 110 by being physically inserted into the connector 201. In addition, power is supplied from the power supply control circuit 119. Switches 203 and 204 are turned on when the insertion board 200 is completely inserted, and a detection circuit 205 that determines whether the switches 203 and 204 are normal or abnormal. These switches 203 and 204 are provided at such a height that they are turned on by the card portion (projection portion of the insertion board) when the insertion board 200 is completely inserted. Are connected by a logical product circuit. For example, it is assumed that if the card edge has an electrode part of 30 mm and is lifted by 20 mm, the contact is insufficient and a malfunction occurs due to poor contact. If the insertion board floats 15 mm due to force or vibration applied after insertion, the insertion board monitoring device 202 determines that there is an abnormality.

  FIG. 3 shows a power supply control circuit. In the power supply control circuit, there is an FET element, and a high signal is normally input from the CPU 101, so that power is supplied to the insertion board 200. However, when a Lo signal is input from the CPU 101, the power supply is cut off. The

  FIG. 4 shows the configuration of the software 117 stored in the main storage device 111. An OS 130, an application 131, and a configuration control program 132 are read from the disk device 113 and stored in the main memory (main storage device) 111 of the electronic computer 100, and the application 131 and the configuration control program 132 are executed on the OS 130 in the CPU 110. Has been. The configuration control program 132 switches between the active system insertion board 200a and the standby system insertion board 200b, power supply control from the power supply control circuit 119 to the insertion board 200, and access control for permitting / prohibiting access to the insertion board 200. It is a program that performs. The insertion / removal monitoring program 118 is interlocked with the insertion board monitoring device 202 and constantly monitors the mating state of the insertion board 200. The configuration control program 132 is activated when the insertion board monitoring apparatus 202 detects that the mating state of the insertion board 200 is becoming unstable.

  FIG. 5 is a block diagram illustrating a specific operation of the first embodiment of the present invention.

  The insertion board monitoring device 202 determines that the switches 203 and 204 of the a contact 203 and the b contact 204 are both in the on state, and determines that both are in the off state. When the contact of is in the off state, it is judged as a slight minor abnormality. The power supply control circuit 119 controls the power supplied to the insertion board. The configuration control program 132 switches to the standby system insertion board 200b after the insertion board 200a whose mating state is unstable is degenerated.

  The operation will be described with reference to the flowchart shown in FIG.

  In step 202, if the mating state of the insertion board 200 becomes unstable due to force or vibration applied to the insertion board 200 after insertion, the insertion board monitoring device 202 detects an abnormality. That is, when one of the switch 203 and the switch 204 is abnormal (relatively slight abnormality than severe), a control signal is sent from the insertion board monitoring device 202 to the central processing unit (CPU) 110 after detection. The central processing unit (CPU) 110, which is output (110-a) and receives the control signal output from the insertion board monitoring device 202, has all access to the insertion board 200 whose mating state is unstable. It is prohibited (110-b). Thereafter, a control signal is output to the power supply control circuit 119 (110-c), and the access is switched to the insertion board in which the mating state is stable (110-d). The power supply control circuit 119 that has received the control signal output from the central processing unit (CPU) 110 cuts off the power supply to the insertion board 200 whose mating state is unstable (119), and is in the mating state. The insertion substrate 200a that is unstable is degenerated. At the same time, the configuration control program 132 takes over a set value such as an IP address to the insertion board (standby expansion board) 200b and continues the operation.

  Further, it is determined whether the teaming configuration is set (132-a). If the teaming configuration is used, the IP address of the spare LAN card is handed over (132-b), and the processing is continued with the spare LAN card (132-c). On the other hand, if it is not the teaming configuration, it is further determined whether it is a duplex configuration (132-d). If it is a duplex configuration, it is switched to the standby system (132-e), and if it is not the duplex configuration, it continues (132-f).

  The reference numerals 110-a to 110-d indicate the operation of the CPU 110, and 132-a to 132-e indicate the operation of the CPU 110 as the configuration control program 132. Reference numeral 119 indicates the operation of the power supply control circuit 119.

  It is also effective in an electronic computer composed of a plurality of computers.

  FIG. 7 shows the configuration of an electronic computer related to Example 2 of the present invention. The same components as those in the embodiment are denoted by the same reference numerals. As shown in the figure, the multi-system system according to the present embodiment is a dual system composed of two computers. That is, the reference numeral (-0) indicates the main system, and the reference numeral (-1) indicates the secondary system. However, you may comprise three or more computers. In FIG. 7, reference numerals 100 and 101 denote an active computer and a standby computer, respectively. By system switching, the active computer 100 operates as a standby computer, and the standby computer 101 operates as an active computer.

  The components of each electronic computer are the same as those of the electronic computer of the first embodiment.

  The electronic computers 100 and 101 according to the second embodiment include a LAN board 115 (115a-0, 115b-0, 115c-0, 115a-1, 115b-1, 115c-1) as an insertion board.

  The LAN board 115 is connected to the LANs 115c-0 and 115c-1, the LAN boards 115b-0 and 115b-1, and the LAN boards 115a-0 and 115a-1, respectively. Communication is performed with the computer 101 connected to the general-purpose networks 104 and 105. As a general-purpose network, there is Ethernet (registered trademark) (IEEE 802.3) which is widely used.

  FIG. 8 is a block diagram showing Embodiment 2 of the present invention.

  If the mating state of the LAN board 115 becomes unstable due to force or vibration applied to the LAN board 115 after insertion, the insertion board monitoring device 202 detects an abnormality. After the detection, the central processing unit (CPU) 110 that receives the control signal output from the insertion board monitoring device 202 is output a control signal from the insertion board monitoring device 202 to the central processing unit (CPU) 110. All accesses to the LAN board 115a whose mating state is unstable are prohibited. Thereafter, the power supply control circuit 119 outputs a control signal to the power supply control circuit 119 and receives the control signal output from the central processing unit (CPU) 110. The power supply control circuit 119 has a LAN board 115a whose mating state is unstable. In contrast, the supply of power is cut off, and the LAN board 115a whose fitting state is unstable is degenerated. At the same time, the system is continued by switching from the active system / computer 106 to the normal standby system computer 101 by the configuration control program 133.

  This switching is performed by transmitting switching instruction information from the computer 100 to the computer 101 via the Ethernets 103 to 105, whereby the transmitted computer 100 is voluntarily degenerated, and the received computer 101 operates as an active electronic computer. To do.

  The feature points of the embodiment described above will be described repeatedly. An insertion board monitoring device that constantly monitors the mating state of the insertion board, a power supply control circuit that controls the power supplied to the insertion board, and the mating state are inadequate. After a stable insertion board is degenerated, it is constituted by a configuration control program for switching to a standby computer and a standby insertion board. When an inserted board whose mating state is becoming unstable is detected by the inserted board monitoring device, the target inserted board is degenerated by the central processing unit (CPU) and the power supply control circuit, and the system malfunctions due to poor contact. Is prevented. Furthermore, the configuration control program operates simultaneously with the degeneration processing, and the system can be continued by switching to the standby system computer and the standby system insertion board.

  As described above, problems caused by degeneration of the abnormality occurrence site can be prevented, and the system can be safely continued by the configuration control program. This system protection control method is expected to be applied to social infrastructures that require high reliability.
