Description

  The present invention relates to a virus scanning method for an FA machine tool, an FA machine tool using the method, an FA system, an auxiliary storage device, a computer program, and a notification pluggable device.

The FA machine tool incorporates a machine control program including numerical data for machining and an OS (operating system) as basic software for starting up the machine control program. In recent years, as the functions of FA (Factory Automation) such as NC machine tools and industrial robots are diversified and generalized, general purpose embedded OSs such as Windows (registered trademark) XPe are used in computers that control FA machine tools. Operating system) is adopted. In production sites, FA machine tools are normally used without being connected to a network in order to prevent damage from computer virus infection and prevent leakage of confidential information. For example, control programs and data are created on a PC (personal computer) installed at a location different from the production line, and stored in a removable storage device such as a USB memory or compact flash (registered trademark) (a type of memory card). Since then, it has been installed on FA machine tools. In addition, work data and production management data are also stored in these pluggable storage devices, and thereafter managed by a PC in another location.

However, when a pluggable storage device is infected from a PC that has created a machine control program, the machine tool is secondarily infected from the pluggable storage device. If the machine tool OS or the control program is infected with a virus, control will be out of order, and not only will it not be possible to execute the desired work, but there is also a concern that the machine may run away unexpectedly.

In this regard, there has been proposed a device for preventing secondary infection by interposing a device for checking the presence of virus infection between the portable storage medium and the host when installing a program or the like from the portable storage medium to the host. (Japanese Patent Laid-Open No. 2009-212524), it is not possible to check whether a PC that has already been infected is infected with a virus or to remove an infected virus.

Conventionally, due to the need for maintenance and management of consumable parts of machine tools, there has been a usage form in which a user management device for managing a plurality of NC machine tools is connected via an intranet and an Internet mail server is accessed via a router. (JP 2004-295348 A). It is said that it is a method that prevents infection as much as possible because it is a configuration that does not connect to the Internet all the time, but since the configuration is such that the user management device accesses the mail server, the possibility of virus infection is denied. Can not. This method does not provide any means of checking for or eliminating virus infection. If an NC machine tool is infected with a virus, it takes a lot of labor to remove the virus from the machine tool, and the operating rate of the machine tool is greatly reduced, which deteriorates productivity. If the product on the market is collected (recalled), the damage will be immeasurable.

JP2009-2111524 JP 2004-295348 A

Therefore, in the present invention, it is not assumed that FA machine tools such as NC machine tools and robot manipulators are normally infected with viruses, and input means such as a display device and a keyboard are not provided.

(Basic configuration of FA system)
FIG. 1 shows an example of the environment of an FA machine tool according to an embodiment of the present invention. As shown in FIG. 1, a robot manipulator 1 (1-1 to 1-n), which is an FA machine tool, and an NC machine tool (2-1 to 2-2) are connected to a management PC 3 via a LAN for production management. Yes. As shown in FIG. 2, the robot manipulator 1 is provided in parallel with the production line, and simultaneously welds a workpiece, for example, an automobile. The NC machine tool 2-1 is a punching machine for each part (steel plate) of an automobile body, and the NC machine tool 2-2 is a press for forming and processing the punched parts into a three-dimensional curved surface according to the design drawing. Machine. Each NC machine tool (2-1, 2-2) is arranged at a location away from the group of robot manipulators (1-1 to 1-n). Although not shown, there are other robot manipulators that perform body painting operations and other necessary operations. There are also stand-alone FA machine tools that are not connected to the LAN.

The conventional robot manipulator 1 has a control device 11 for controlling the robot manipulator 1 itself, for example, as shown in FIG. 3, and the control device 11 includes a CPU 111 that controls the robot manipulator 1 in an integrated manner, and Ethernet. LAN interface 112 connected to the management PC 3 based on the TCP / IP standard, a machine control program 1142 for the robot manipulator 1, and an OS 1141 for the machine control program 1142 (for example, Windows (registered trademark))

The machine tool 22 includes a drive unit 221 (a motor for driving the cutter) that drives a driven unit 222 (for example, a cutter for cutting an iron plate). The drive unit 221 is controlled by a drive control unit 215 controlled by the CPU 211, and executes a predetermined work. The NC machine tool 2 is generally equipped with an input / output device for an operator to operate the NC machine tool 2 as standard. Examples of the input / output device include a display device 216 such as a plasma display, a transparent touch panel 217 for menu input, and a numeric keypad 218. The transparent touch panel 217 is attached to the surface of the display device 216 in an integrated structure, and is a device that detects the position touched by the operator, and is used for inputting various menus displayed on the display screen. As in the case of the robot manipulator 1, the auxiliary storage device 214 is a hard disk drive (HDD) or a solid state drive (SSD), and the main storage device 213 can also be constituted by a DRAM.

  Although not shown in FIGS. 3 and 4, both the control devices 11 and 21 are BIOS (not shown) for starting up the OSs 1141 and 2141 when the power is supplied to the robot manipulator 1 and the NC machine tool 2, respectively. Z). As described above, neither the conventional robot manipulator 1 nor the NC machine tool 2 has a configuration for executing virus scanning.

<First embodiment: NC machine tool / notification by display device>
A first embodiment of the present invention (in the case of an NC machine tool / notification by a display device) will be described below with reference to the drawings. First, an auxiliary storage device used in the NC machine tool according to the embodiment of the present invention will be described with reference to FIGS. 5, 6, and 8 (configuration example of the NC machine tool of the present invention). The auxiliary storage device 214 ′ (FIG. 7) of the present invention uses an HDD or SSD as in the conventional case. As shown in FIG. 5, the configuration includes a control unit 214′-1 that controls writing and reading of data in the storage unit 214′-2 and the storage unit 214′-2. In the case of the HDD, the storage unit 214′-2 is formed of a magnetic disk, and in the case of the SSD, the storage unit 214′-2 is configured by a nonvolatile semiconductor memory such as a NAND flash memory. In the case of an HDD, the control unit 214′-1 includes a mechanical mechanism that controls seeking of the magnetic head and reading and writing of data. In the case of an SSD, the controller 214′-1 includes a processor (integrated controller) and a firmware that is a control program. Circuit). The control unit 214′-1 is mechanically and electrically connected to the CPU 211 via an IDE interface and controlled.

  FIG. 6 shows an example of the internal configuration of the auxiliary storage device 214 '. In this embodiment, four partitions (partitions “0” to “3”) are set in the additional auxiliary storage device 214 ′ using the OS storage machine. The partition “0” stores a work control program 2142 and an operating system a 2141 (hereinafter referred to as OSa) for the work control program 2142. The partition “1” stores a virus scan program 2144 and an operating system b2143 (hereinafter referred to as OSb) for the virus scan program 2144. The partition “2” is an area for storing a file 2145 for storing a virus scan LOG, a file 2146 for storing a work LOG, and a virus definition file 2147, which will be described later. The partition “3” is an area for isolating a virus-infected file described later.

When OSa and OSb are respectively stored in the partition “0” and the partition “1”, an MBR (master boot record) is stored in an area starting from the sector “0” of the auxiliary storage device 214 ′ (hereinafter referred to as an MBR storage area). . In the MBR storage area, a partition table in which information of each partition is recorded, a boot loader a used when the BIOS starts OSa, and a boot loader b used when the BIOS starts OSb are written and stored. The Next, the work control program 2142 is stored in the partition “0”, and the virus scan program 2144 of the present invention is stored in the partition “1”. In the partition “2”, a further virus scan LOG file 2145, a further work LOG file 2146, and the latest virus definition file 2147 are stored.

Hereinafter, a virus scanning method in the NC machine tool 2 ′ of the present invention will be described with reference to FIGS. 7 to 9. FIG. 7 shows an example of the internal configuration of the NC machine tool 2 'according to the present invention. When power is turned on to the NC machine tool 2 ′, the BIOS is first activated, and an operator instruction waiting screen is displayed on the display device 216. That is, a screen for selecting which OSa or OSb operating system to start is displayed. When executing virus scanning, the operator inputs the use of the OSb from the numeric keypad 218 or the menu screen (touch panel 217). Then, the BIOS reads the boot loader b in which information necessary for reading the OSb is recorded, determines the location of the OSb from the information of the boot loader b, loads the OSb into the main storage device 213, and starts the OSb. When the OSb is activated, the OSb loads and activates the virus scan program 2144 to the main storage device 213 by its own function (the OSb is set to activate the virus scan program 2144 after activation).

Hereinafter, the contents of the virus scanning program 2144 of the present invention will be described with reference to FIG. As shown in FIG. 8, the virus scan program 2144 used in the NC machine tool 2 ′ includes a file search function, a virus scan function, a virus removal function, an infected file quarantine function, a scan status notification function (that a virus scan is being executed). Notification function), scan result notification function, LOG (scan history) write / issue function, and virus definition file update function. It is a design matter whether it has a virus removal function and an infected file isolation function. You may make it selectable as an option.

Here, the “virus scanning function” refers to a function for checking whether or not a file stored in the auxiliary storage device 214 ′ is infected with a virus. The “virus removal function” is a function for removing a virus program from an infected file. The removal means that the infected virus program itself can be erased or encrypted from the auxiliary storage device 214 ′ and can be operated on the auxiliary storage device 214 ′ and the host machine (NC machine tool 2 ′ in this embodiment) incorporating the auxiliary storage device 214 ′. It means to lose. “Infected file quarantine function” is a function to move an infected file to a predetermined location (partition “3” in this embodiment) in the auxiliary storage device 214 ′ when a virus found as a result of scanning cannot be removed. Say. At this time, the infected file is appropriately processed such as encryption so that it cannot be activated thereafter. The virus scan is executed by vaccine software (strictly, a virus detection engine) included in the virus scan program 2144.

The virus scan program 2144 and the virus definition file 2147 are inseparable from each other in the virus scan function, and both exist as files that can be recognized by the OSb file system.

  When the virus scan program 2144 is loaded into the main storage device 213 and started, the virus definition file 2147 is also loaded. Then, based on the file search function, all files stored in the auxiliary storage device 214 ′ are searched, and a list of file names is created in the main storage device 213. The virus scan program 2144 sequentially scans the created list file, refers to the virus definition file 2147, and scans for the presence or absence of a virus defined in the definition file 2147. Of course, if there are other data files for NC machine tools, they are also scanned.

Next, notification in the NC machine tool 2 'will be described with reference to FIG. When the virus scan program 2144 starts scanning, the display device 216 displays “Scanning in progress”.

When the scan is completed, if the virus scan program 2144 is not provided with a virus removal function and an infected file isolation function, only the scan result (infectious presence / absence) is notified. When no virus is found, the display device 216 displays “No virus found”. When a virus is found, the message “Virus was found” is displayed.

  When the virus scan program 2144 is provided with a virus removal function and an infected file isolation function, the presence / absence of virus infection and the removal of the virus or isolation of the infected file are performed in a series of operations. When a virus is found, it does not simply notify the fact that the virus exists, but disinfects the virus or isolates the infected file and notifies the result. If a virus is found and the virus is removed, the message “The virus has been removed” is displayed. When the infected file is quarantined to the partition “3”, “Infected file is quarantined” is displayed. When quarantining, if a virus-infected file is encrypted, the virus is frozen and can no longer operate.

For the sake of safety, after the infected file is quarantined, if the auxiliary storage device 214 ′ is an SSD, the virus scan program 2144 issues a vendor command for deleting the partition “3” to the SSD control unit 214′-1, and the control unit Designate a physical block that constitutes the partition “3” to the NAND flash memory 214′-1 being the storage unit 214′-2, issue an erase command to remove the charge of the cell of the physical block, and It is a good idea to completely erase all infected files. The designation of the physical block address of the partition “3” by the control unit 214′-1 that is the SSD controller is performed by first calculating the logical block address of the partition “3” from the partition table of the MBR storage area, This can be executed by referring to the block / physical block conversion table. In the case of the HDD, the infected foul can be erased by repeatedly overwriting meaningless data in the entire area of the partition “3”.

The various notifications of the virus scan results described above are executed by the scan result notification function of the virus scan program 2144.

Further, the virus scan program 2144 writes and stores the scan result in the virus scan LOG file 2145 of the partition “2” based on the LOG writing function. The data to be recorded as the history includes the machine tool number (ID), the scan date / time, and the scan result (the presence / absence of infection, the name of the infected file, the name of the infected virus, the presence / absence of removal / quarantine, etc.).

Next, the virus definition file update function will be described. As is well known, the intranet is configured based on Ethernet, which is a physical standard, and TCP / IP protocol, which is a communication standard. The management PC 3 is connected to the Internet network 4, and a new virus definition list is provided from time to time by a virus scan software vendor, which is updated and stored on the PC 3. When the virus scan program 2144 starts up after OSb starts, it accesses by specifying the IP address on the intranet of the management PC 3, downloads the latest definition file on the PC 3, and updates the definition file in the virus scan program file 2144 To do. As a result, the virus scan program 2144 can always execute a virus scan with the latest virus definition file provided by the vendor.

In the NC machine tool 2 ', after completing the virus scan, the operator ends OSb and turns off the power of the NC machine tool 2'. Then, the NC machine tool 2 'displays the BIOS screen again. When it is confirmed that the virus is not infected and the operator starts the work, OSa is selected on the BIOS screen. Then, OSa starts. After the OSa is started, the operator selects and inputs a necessary work control program 2142 from a menu input screen displayed by the OSa. When the OSa loads the work control program 2142 to the main storage device 213, the work work enters a standby state. Thereafter, a work operation is started in accordance with an operation start instruction from the display screen 216 by the operator.

When the work is finished, the work control program 2142 writes the result in the work LOG file 2146 of the partition “2” and saves it. This record includes the machine tool number (ID), the date / time of the machine, and the number of machines. Needless to say, the information may be written together when the work for the day is completed.

<Second Example: Robot Manipulator / Sound Notification>
Next, a second embodiment (in the case of a robot manipulator / notification by sound) of the present invention will be described with reference to the drawings. As described above, a robot manipulator usually does not include a display device as an output device, or a keyboard or touch panel as an input device. Therefore, the virus scan in the robot manipulator is executed with a configuration different from that of the NC machine tool. Hereinafter, description will be made with reference to the drawings (FIGS. 10 to 13).

FIG. 10 shows a second internal configuration example of the auxiliary storage device, which uses an SSD (which may be an HDD) and is built in the robot manipulator. As shown in the drawing, the MBR storage area A for OSa and the MBR storage area B for OSb are divided. As shown in FIG. 11 (configuration example of the robot manipulator of the present invention), the auxiliary storage device 114 ′ is provided with a switch 114′-SW for making the MBR storage area A and the partition “0” visible and hidden from the BIOS. Yes. This switch 114′-SW is a physical switch that can be operated by an operator from the outside of the casing of the auxiliary storage device 114 ′. As shown in FIG. 12, the controller 114′-1 of the SSD that is the auxiliary storage device 114 ′. Normally, when the switch 114′-SW is OFF, the MBR storage area A and the partition “0” cannot be seen from the BIOS as shown in FIG.

As a result, when the virus scan is executed, the switch 114'-SW is turned off. In this state, after the robot manipulator 1 'is turned on, the BIOS recognizes the first sector of the MBR storage area B as sector "0". As a result, the BIOS activates the OSb, and the activated OSb activates the virus scan program 1144 to execute virus scan. The virus scan program 1144 to be used may be the same as that described in the first embodiment (NC machine tool 2 ').

On the other hand, when performing normal work, the operator turns on the switch 114'-SW and then turns on the power of the robot manipulator 1 '. Then, the MBR storage area A and the partition “0” can be seen from the BIOS, and the first sector of the MBR storage area A is recognized as the sector “0”. As a result, the BIOS activates OSa when the switch 114'-SW is ON, and the activated OSa activates the machining control program 1142 to execute normal machining control. In the case of the robot manipulator 1 ′, the work can be appropriately started by the action of a sensor (not shown) provided as a standard in the robot manipulator 1 ′. In the case of the robot manipulator 1 ′, the work on the workpiece is followed in advance, and machining numerical data (including the three-dimensional coordinates of the work location) is collected there, and a predetermined work such as welding is performed based on the data. It can be carried out.

The notification by sound in the robot manipulator 1 ′ will be described with reference to FIG. 9 used in the description of the first embodiment. In the robot manipulator 1 ′, a speaker provided as standard on the robot manipulator 1 ′ is used as the notification means 117 (see FIG. 11), and the operator is notified with sound. When the virus scan is started based on the virus scan function of the virus scan program 1144, the robot manipulator 1 ′ indicates that the virus scan program 1144 emits the first type sound from the notification means 117 and that the scan is being performed. Notify the operator. The first type of sound is composed of light melodies.

When the scan is completed, if the virus scan program 1144 is not provided with a virus scan program removal function and an infected file isolation function, only the scan result (infectious presence / absence) is notified. When the defined virus is not found, it is judged that safety is confirmed in terms of security. Therefore, another light melody (second type sound) different from the first type sound is used. To inform. When a virus is found, a high-pitched buzzer is continuously sounded as the third type of sound to inform the operator that work must be stopped and confirmed.

When the virus scan program 1144 is provided with a virus removal function and an infected file isolation function, a virus infection check and virus removal or infected file isolation are performed in a series of operations, as in the first embodiment. When a virus is found, it does not simply notify the fact that the virus exists, but disinfects the virus or isolates the infected file and notifies the result. If a virus is found and removed, a fourth type of sound, for example, a relatively low intermittent buzzer, informs you (the fact that it has been removed and is safe but it has been infected with the virus) ). If a virus is found and the infected file is quarantined in partition “3”, it will be notified by a fifth type of sound, for example, a relatively high intermittent buzzer sound (although it is isolated and safe for the time being, Inform the fact that the virus was infected).

  The deletion of the partition “3” when the infected file is quarantined, the writing of the scan result to the virus scan LOG file 1145, the writing of the work record to the work LOG file 1146, and the update of the virus definition file 1147 are described above. This is executed in the same manner as the NC machine tool 2 ′.

<Third Example: Notification Using Notification Pluggable Device / Notification by LED>
Next, the notification pluggable device of the present invention will be described with reference to FIG. The robot manipulator 1 ′ has a USB interface 116 ′ connected to the CPU 111 as a host interface, and the USB terminal of the notification pluggable device 5 is attached to a USB port (not shown) of the USB interface 116 ′. Thus, the operator of the robot manipulator 1 ′ is configured so that the scan result can be visually recognized. The auxiliary storage device used is the same as that described in the second embodiment.

FIG. 15 shows an example of the function of the virus scan program 1144 ′ used when notification is made by the pluggable device 5. As shown in the figure, the virus scan program 1144 ′ includes a file search function, a virus scan function, a virus removal function, an infected file quarantine function, a scan status notification command issuance function (a function for notifying that a virus scan is being executed), and a scan result. It has a notification command issuing function, a LOG (scan history) writing function, and a virus definition file updating function.

The notification pluggable device 5 has a USB interface 51 connected to the controller 52 inside. The controller 52 interprets a command issued by the virus scan program 1144 ′ by the firmware 521 and notifies the notification means 53 of the command. It is. As the notification means 53, for example, one red light emitting diode (hereinafter, red LED) and one blue light emitting diode (hereinafter, blue LED) are provided.

  FIG. 16 shows a notification example by the notification pluggable device 5. As shown in the drawing, both the blue LED and the red LED blink while the scan is being executed.

When the scan is completed, if the virus scan program 1144 'is not provided with a virus removal function and an infected file isolation function, only the scan result (the presence or absence of infection) is notified. When no virus is found, the blue LED is turned on and the red LED is turned off. When a virus is found, the blue LED is turned off and the red LED is lit to notify.

  When the virus scan program 1144 ′ is equipped with a virus removal function and an infected file isolation function, a series of operations, such as checking for the presence or absence of virus infection and removal of a virus or isolation of an infected file, as in the first and second embodiments. Done. When a virus is found, it does not simply notify the fact that the virus exists, but disinfects the virus or isolates the infected file and notifies the result. When a virus is found and removed, the blue LED is lit and the red LED is blinking. When the infected file is isolated in the partition “3”, the blue LED turns off and the red LED blinks. Safety can be displayed by turning on the blue LED, and warning can be displayed by turning on the red LED. After the scan is completed, the pluggable device 5 is removed from the main body of the robot manipulator 1 ″. Since the notification pluggable device 5 of the present invention does not require a storage unit such as a NAND flash memory, it may be infected with a virus. There is no.

The notification that the scan is being executed is executed when the virus scan program 1144 ′ issues a scan status notification command interpretable by the firmware 521 to the controller 52 via the OSb based on the scan status notification command issue function. . That is, the firmware 521 interprets the command, and notifies the operator that the scan is being executed by the notification means 53. The notification of the scan result is executed when the virus scan program 1144 issues a scan status notification command interpretable by the firmware 521 to the controller 52 via the OSb based on the scan status notification command issue function. Lighting, blinking, and the like of the LED are controlled by a processor (not shown) of the controller 52. Depending on the severity of the infected virus, the blinking speed of the red LED may be changed.

Note that a speaker may be provided in the pluggable device 5 so that only the sound or the sound is notified as in the second embodiment. In the case of notification by sound, each melody and buzzer sound may be programmed in the firmware 521 in advance. In addition, a small liquid crystal display device may be integrally provided in the housing of the pluggable device 5 instead of the LED, and the display as in the first embodiment may be performed by the liquid crystal display device. In this case, the name of the virus that has been disinfected or infected can be displayed.

Moreover, while notifying by LED of the device 5, similarly to 1st Embodiment (NC machine tool 2 '), notification sound (melody etc.) is programmed into the virus scan program 1144', and notification by sound is performed by the robot manipulator 1. The notification means 117 may be used together. Since the notification insertion / removal device 5 does not have a memory for preventing virus infection, the LOG of the scan result is written in the virus scan LOG file 1145 of the auxiliary storage device 114 ′ as in the above-described embodiment.

(Modification)
The informing means 52 of the informing / removable device 5 for informing may be a digital signal for short-range wireless communication such as infrared rays or Bluetooth in addition to the LED, and may transmit the scan result to an external device. In that case, you may alert | report in combination with LED etc. 11 and 14, the control device 11 ′ of the robot manipulator 1 ′ is shown in the main body of the robot manipulator 1 ′, but is connected to the main body with a cable and is configured as a physically independent box. Needless to say, it may be.
