Abstract

PROBLEM TO BE SOLVED: To reduce the probability of the occurrence of a processing waiting state of a control driver.SOLUTION: In a peripheral device control fault avoidance method to be executed by a computer connected to a peripheral device and provided with an OS, the computer executes a detection step (S22) of detecting an error state of a control driver controlling the peripheral device and a recovery processing step (S30) of performing recovery processing in response to detection of the error state. In the recovery processing step, the OS is caused to execute reboot (S16). The error state occurs when a control module (WIA module) activated before the control driver (TWAIN driver) is frozen and the control driver enters into a processing waiting state.

Description

  The present invention relates to a peripheral device control failure avoidance method, a peripheral device control failure avoidance program, a processing apparatus, and a processing system.

  In a financial institution such as a bank or post office, a customer visits the financial institution's branch in order to conduct cash deposits, withdrawals, transfers, etc., and fills in various items according to the purpose of the visit. To do. A sales point counter terminal is provided with a scanner. The scanner reads a form image, and a PC (Personal Computer) recognizes characters.

  Conventionally, there is a technique for dealing with a failure (error) in a device or system such as a scanner or a PC. For example, Patent Document 1 describes a money handling machine that prompts cleaning and replacement of a faulty part when the same error code reaches a set number of times. Japanese Patent Laid-Open No. 2004-268531 monitors the operating state of the main unit operating with the auxiliary power source after supplying AC power to the main unit of the system and before turning on the system power, and when the failure detection means detects a failure of the main unit. A power supply control technique is described in which AC power supply to the main device is temporarily stopped and then AC power supply is started again.

  In addition, the OS (Operations System) used in the PC includes a WIA (Windows (registered trademark) Image Acquisition) module and is resident in memory at startup, so that peripherals such as WIA-compatible digital cameras and scanners can be used. When the device is connected to a personal computer, the personal computer automatically recognizes the peripheral device and can capture images in a predetermined folder. The peripheral device is provided with a TWAIN (Technology Without An Interesting Name) driver dedicated to the device, and can be linked with application software.

JP 2010-257323 A (Claim 11) JP 2010-152421 A (Claim 1)

  By the way, the PC may execute a startup check program for checking the startup status of the peripheral device at the startup. In this case, the TWAIN driver may be executed immediately after the peripheral device is automatically recognized by the WIA module, and the WIA module and the TWAIN driver may be processed in parallel. At this time, the WIA module (control module) may freeze, and as a result, the TWAIN driver (control driver) enters a process waiting state (control failure occurrence state).

  Accordingly, an object of the present invention is to provide a peripheral device control failure avoidance method, a peripheral device control failure avoidance program, a processing device, and a processing system that can reduce the probability of occurrence of a process waiting state of a control driver.

  In order to solve the above-described problems, the present invention provides a peripheral device activation method executed by a computer (100) connected to a peripheral device (for example, the scanner 210) and having an OS, and a control driver for controlling the peripheral device The computer executes a detection process (S22) for detecting an error state (for example, the TWAIN driver 520) and a recovery process (S30) for performing a recovery process when the error state is detected, and the recovery The process is characterized by causing the OS to restart (S16). In addition, the code | symbol etc. in () are illustrations.

  The OS has a control module (for example, a WIA module 514) resident at startup, and the control driver also operates. For this reason, the control module to be activated first grabs the thread, and as a result, the control driver may wait for processing. In this state, the detection unit does not respond even if it asks the control driver to check the status, resulting in a scanner activation error. In order to avoid this failure, a confirmation screen prompting the OS to restart is displayed on the display unit, the OS is restarted, and the error state is resolved by restarting the OS. If the occurrence probability of a scanner activation error is less than 100%, the scanner activation error is resolved by restarting the OS a plurality of times. In addition, since the initial hardware settings may differ between the startup at power-on (Cold-Start) and the OS restart (for example, Warm-Start), even if a scanner startup error occurs at power-on The scanner activation error may be resolved by restarting the OS.

  According to the present invention, it is possible to reduce the probability of occurrence of a processing wait state of a control driver.

The scanner 210 is a non-contact scanner that images a form placed on the mat portion with a CCD camera. The scanner PC 100 includes a monitor 110 as a display unit, and reads an image read by the scanner 210 as an OCR (Optical Character Recognition). This is a client machine in which the user performs a collation operation between the form image and the recognized character subjected to the OCR conversion. In addition, the scanner PC 100 transfers data to the machine room 350 and inquires about data. The image read by the scanner 210 is not only a form image but also an image of an identification card such as a license or an image of a receipt (medical fee description) used in a medical institution.

  The business center 300 includes an entry PC 310 and a center printer 320, and the entry PC 310 is a client machine that performs data input and inquiry. The machine room 350 includes a DB (Data Base) server, an AP (Application) server, and a GW (Gate Way) server, and is connected to each other via a LAN. The DB server stores read images, transaction data, and the like, and the AP server stores application software, and the client application downloads and uses the stored application software or executes it in the AP server. . The GW server is a server that communicates with the host and the branch offices 200 and 201 via the NW. Hereinafter, the DB server and the AP server communicate with each other via the GW server, but are omitted.

  The business processing scanner system 1000 can, for example, send scanned form image data and its OCR data from the sales offices 200 and 201 to the business center 300, and can total and query the data. Further, the DB server can minimize the storage on the paper medium by storing these data. The scanner PC 100 of the sales office 200 performs only reading using the scanner 210, and the scanner PC 100 transmits the read image data to the DB server of the machine room 350, and the entry PC of the office center 300 is stored in the DB server. The image of the read image data is subjected to OCR conversion, and the user may perform office processing such as verification.

FIG. 2 is a hardware configuration diagram of the processing apparatus (scanner PC) according to the first embodiment of the present invention.
The scanner PC 100 includes a main power source 10 and a sub power source 15 connected to a commercial power source AC, a main CPU (Central Processing Unit) 20, a power management circuit 25, a power switch 26, and a RAM (Random Access Memory) 30. A boot ROM (Read Only Memory) 32, an HDD (Hard Disk Drive) 35 as a nonvolatile storage unit, a USB (Universal Serial Bus) I / F 40, and a monitor I / F 45. It is configured to start up by a temporary short circuit and restart by software control.

  The main power supply 10 and the sub power supply 15 are connected to a commercial power supply AC. When the PS_ON signal is input from the external power management circuit 25, the main power supply 10 generates a DC voltage such as + 5V, and the sub power supply 15 always generates a + 5V voltage (+ 5VSB (Stand By)). Each power supply supplies DC power to each part. The main power supply 10 and the sub power supply 15 are integrated and are generally referred to as “ATX power supply”.

  The main CPU 20 can support multi-threads by multi-core (for example, 4 cores and 4 threads), or create a pseudo core in a core that has only one physically, and two divided threads. It is possible to execute them simultaneously (for example, 2 cores and 4 threads). Here, “thread” means the smallest processing unit in which a series of instructions are processed in order. Multithread means that a single process such as an application has multiple threads. It is divided into parallel processing.

  The power management circuit 25 is always supplied with power from the sub power supply 15, monitors the short circuit / open state of the power switch 26, and performs power control (including power saving control) for the main CPU 20 and the like. CPU. When the power switch 26 is temporarily short-circuited, the power management circuit 25 activates the main CPU 20, the RAM 30, and the boot ROM 32 by starting up the main power supply 10 in response to the PS_ON signal and releasing the reset. Here, the boot ROM 32 stores BIOS (Basic Input Output System) and the like.

  The HDD 35 is a non-volatile storage unit having a head area of MBR (Master Boot Recode) and storing an OS and application programs. The MBR stores a partition table that records the start / end positions of partitions on the hard disk, the file system being used, whether or not active, and an initial program loader (also referred to as a bootstrap loader). The HDD 35 stores a counter used in the second embodiment, and the counter value is not initialized by restarting the OS.

  When the main CPU 20 and the boot ROM 32 are activated, the main CPU 20 performs detection, hardware initialization, and various settings of peripheral device interfaces (USB I / F 40, monitor I / F 45, etc.), reads the initial program loader from the HDD 35, The OS and application programs are expanded in the RAM 30 and processing is executed on the RAM 30. In the case of restarting, a part of the inspection and initialization may be omitted, and reading of the initial program loader may be started or the OS may be started (Warm-Start). That is, the scanner PC 100 may have different hardware settings for startup (Cold-Start) at power-on and restart.

  A USB (Universal Serial Bus) I / F 40 is a USB device controller connected to the store printer 220 and the scanner 210. The monitor I / F 45 is an interface connected to the monitor 110 as a display unit, and includes a VRAM.

FIG. 3 is a software configuration diagram of the processing apparatus (scanner PC) according to the first embodiment of the present invention.
A program stored in the HDD 35 and expanded in the RAM 30 and executed by the main CPU 20 includes an OS 510, application software 550, a display driver 516, and a printer driver 518, which are installed in advance.

  In particular, the OS 510 includes a restart processing unit 512, and a WIA module 514 is incorporated therein. The restart processing unit 512 is a processing unit that performs restart (Warm-Start) by software. The restart processing unit 512 terminates the activated application software 550, and further uses the boot ROM 32 to perform main processing on the power management circuit 25. The CPU 20 is instructed to start (restart). Note that this restart may be executed after reading out the initial program loader, omitting the hardware check and initial setting by the BIOS.

  The WIA module 514 is a program supported by the OS having a function of recognizing connection of peripheral devices such as the scanner 210 and storing read image data and the like in a predetermined folder. Depending on the version of the OS, WPD (Windows (registered trademark) Portable Devices) may be used instead of WIA.

  The display driver 516 is a program that controls the monitor I / F 45. The printer driver 518 is a dedicated program for controlling the sales office printer 220 via the USB I / F 40 or the like, and is used when printing from the application software 550 (in particular, the OCR program 545).

  The application software 550 includes a scanner activation check program 530, a system activation batch 540 (540a), and an OCR program 545. Here, the system activation batch 540 (540a) is stored in a startup folder defined by the OS 510, and is automatically executed upon activation or restart.

  A TWAIN (Technology Without An Interesting Name) driver 520 is an API (Application Interface) dedicated to the scanner 210. If the OCR program 545 conforms to the TWAIN standard, the TWAIN driver 520 can be read from the OCR program 545. Linkage operation is possible. In addition, both the WIA module 514 and the TWAIN driver 520 are activated by the activation of the OS 510, but the WIA module 514 is activated before the TWAIN driver 520. In FIG. 3, the printer driver 518 and the TWAIN driver 520 are indicated by broken lines, but these broken lines indicate that the programs are dedicated to hardware.

  The scanner activation check program 530 includes a detection unit 532 and a restoration processing unit 534 (534a), and the restoration processing unit 534 (534a) includes a display image generation unit 536 (536a). The detection unit 532 detects an activation error of the scanner 210, and detects a scanner activation error when there is no response even when the status of the scanner 210 is confirmed via the TWAIN driver 520 (when it cannot be detected for a predetermined time or more). To do.

  When the detection unit 532 detects a scanner startup error, the recovery processing unit 534 displays a message screen (OS restart screen (FIG. 4)) prompting the OS to be restarted on the monitor 110 and allows the user to execute the restart. After confirming this, the restart processing unit 512 of the OS 510 executes the restart processing. With this restart, the detection unit 532 detects the scanner start error again. When the detection unit 532 does not detect a scanner activation error, the scanner activation check program 530 (recovery processing unit 534) ends the process and activates the OCR program 545 according to the description of the system activation batch 540a.

  In the case of the OS 510, the system activation batch 540a is a batch file that is executed at the time of activation by being stored in the startup folder. In the system activation batch 540a, the file path of the program is described in the order of execution. In the present embodiment, the file path of the scanner activation check program 530 and the file path of the OCR program 545 are described in this order.

  The OCR program 545 has a reading function that causes the scanner 210 to read a form and the like, a binarized read image (form image, handwritten character image), and a character recognition function that performs OCR conversion on the binary image. It has a transfer function to transfer either or both. The OCR program 545 has a dropout function for recognizing and removing a specific color and a collation function for collating a seal. This specific color is used for the ruled line of the form, and the ruled line can be dropped out.

(Description of operation)
FIG. 5 is a flowchart of a startup process executed by the processing apparatus (scanner PC) according to the first embodiment of the present invention.
First, the user turns on the power switch of the scanner 210 (S10), and turns on the power of the scanner PC 100 (short-circuits the power switch 26 temporarily) (S12). As a result, the OS 510 is activated and the system activation batch 540 stored in the startup folder is executed (S14). By executing the system activation batch 540, the scanner activation check program 530 is executed.

  As the OS 510 is activated, the WIA module 514 is activated as resident software, and the WIA module 514 recognizes the scanner 210. Next, the OS 510 activates the TWAIN driver 520. For this reason, at the time of activation, the OS 510 activates both the WIA module 514 and the TWAIN driver 520, so that both programs may compete (collision). That is, the WIA module 514 that is activated first enters a frozen state in which the thread is grabbed, and as a result, the TWAIN driver 520 enters a process waiting state, which causes a scanner activation error. Note that this thread may mean a multi-thread in which the main CPU 20 performs parallel processing with a plurality of cores.

  The detection unit 532 determines whether or not this scanner activation error has occurred (S22). When a scanner startup error occurs (Yes), the display image generation unit 536a causes the OS restart screen to display “Scanner startup error. Please restart your computer. Do you want to restart now?” (FIG. 4). ) Including a selection button of “Restart now / Restart later”. Then, the recovery processing unit 534 displays the generated OS restart screen (OS restart message) on the monitor 110 (S30).

  When the “restart now” button is pressed (Yes in S24), the restart processing unit 512 of the OS 510 performs the restart process (S16). When the “restart later” button is pressed, the application software 550 itself ends. If a scanner activation error has not occurred in S22, the process ends, and the OS 510 starts activation of the OCR program 545 in accordance with the description of the system activation batch 540.

  According to the present embodiment, the scanner activation check program 530 displays a message prompting the OS 510 to restart, and when the OS 510 is restarted, the WIA module 514 has a dull phenomenon (a state where a thread has been grabbed). (Freeze phenomenon) can be refreshed once. By being refreshed, the processing wait state (control failure occurrence state) of the TWAIN driver 520 is resolved, and the scanner 210 can respond.

  That is, if the probability of occurrence of a scanner activation error is low, the scanner activation error can be resolved by starting the OS when the power is turned on and restarting the OS. Further, when the OS 510 is restarted, the hardware check or initial setting by the BIOS may be omitted, and the reading of the initial boot program may be started or the OS may be restarted (Warm-Start). For this reason, the initial state of the WIA module 514, the TWAIN driver 520, and the like is different between when the power is turned on and when it is restarted, and the WIA module 514 is expected to be refreshed.

(Second Embodiment)
In the first embodiment, when a scanner startup error is detected, the OS 510 is restarted after the OS restart message is displayed. However, a scanner startup error may occur even after a plurality of OS restarts. In this case, the scanner activation error may be resolved by turning OFF / ON the power switch of the scanner 210 as well as restarting the OS.

  The hardware configuration of this embodiment is the same as that of the first embodiment. However, the counter is stored in the HDD 35 as a registry, and the value is not reset even when the OS is restarted. The counter is set to an initial value “1” when no scanner activation error has occurred. The registry is a hierarchical database that stores application settings, user passwords, device driver information, Windows (registered trademark) settings, and all other settings on the PC. The counter value can also be stored in the HDD 35 as a file without being stored as a registry.

FIG. 6 is a software configuration diagram of the processing apparatus (scanner PC) according to the second embodiment of the present invention.
The software configuration diagram of this embodiment is the same as that of the first embodiment, but is different in that it is changed to a scanner activation check program 530b, a restoration processing unit 534b, a display image generation unit 536b, and a system activation batch 540b.
The display image generation unit 536b, which is the difference, generates an instruction message image (FIG. 7) for requesting the user to restart the scanner and the OS, and the recovery processing unit 534b generates a plurality of scanner activation errors. Sometimes, the generated instruction message image is displayed on the monitor 110 to prompt the user to restart the scanner. The system activation batch 540b is described so that the scanner activation check program 530b is activated first, and then the OCR program 545 is activated.

FIG. 8 is a flowchart of the startup process executed by the processing apparatus (scanner PC) according to the second embodiment of the present invention.
First, as in the first embodiment, the user turns on the power switch of the scanner 210 (S10), and turns on the power of the scanner PC 100 (shorts the power switch 26) (S12). As a result, the OS 510 is activated, and the system activation batch 540 is executed from the startup (S14). By executing this system activation batch 540, the scanner activation check program 530b is executed.

  The detection unit 532 determines whether a scanner activation error of the TWAIN driver 520 has occurred (S20). When a scanner activation error occurs (Yes in S20), the recovery processing unit 534b determines whether or not the counter value is equal to or smaller than a predetermined value “5”. When the value of the counter is equal to or smaller than the predetermined value “5” (Yes), the restoration processing unit 534b adds “1” to the counter (S28). That is, the counter value is the initial value “1” + 1 = 2. Then, as in the first embodiment, the display image generation unit 536 displays a message screen (“Scanner is a startup error. Please restart your computer. Do you want to restart now?”) An OS restart screen (FIG. 4) is generated including a selection button of “Restart now / Restart later”. Then, the recovery processing unit 534 displays an OS restart screen (OS restart message) on the monitor 110 (S30).

  When the “restart now” button is pressed (Yes in S32), the recovery processing unit 534b causes the OS 510 to restart, and the restart processing unit 512 of the OS 510 performs the restart process (S16). That is, the OS 510 terminates the processing of the scanner activation check program 530b, reads the initial boot program from the MBR of the HDD 35, and expands the OS 510 in the RAM 30. As a result, the system activation batch 540b is executed again (S14), and it is determined whether or not a scanner activation error has occurred (S20). When the “restart later” button is pressed, the application software 550 itself ends.

  In S26, when the value of the counter exceeds the predetermined value “5”, the display image generation unit 536 reads “Scanner startup error. Restart the scanner and computer. Restart now. Is generated including a selection button of “Restart now / Restart later”. Then, the restoration processing unit 534b causes the monitor 110 to display the generated instruction message image (scanner, OS restart message image) (S34).

  When the “restart now” button is pressed (Yes in S36), the process leaves the scanner activation check program 530b. Then, the user turns off the power of the scanner 210 and turns it back on (ON) to restart the scanner (S18), and the restart processing unit 512 of the OS 510 performs the restart processing (S18). S16). In FIG. 8, it is described that the scanner restart in S18 is executed before the OS restart in S16, but the OS restart may be executed before the scanner restart.

  If no scanner activation error has occurred in S20 (No), the recovery processing unit 534b initializes the counter value to “1” (S38), and the process ends. Then, the OS 510 starts activation of the OCR program 545 according to the description of the system activation batch 540. That is, the scanner activation check program 530b initializes the counter when no error occurs.

  According to the present embodiment, as in the first embodiment, the restart of the OS 510 is executed, so that the dammar phenomenon of the WIA module 514 (a phenomenon in which some thread is held) is refreshed once. And the TWAIN driver 520 waits for processing. Further, if the occurrence probability of the scanner activation error is less than 100%, the scanner activation error is resolved by restarting a plurality of times.

  Further, even if the OS is restarted a plurality of times, if the scanner does not respond normally and a scanner activation error occurs, there is a possibility of some error in the scanner activation check program 530b itself. To refresh this error, it is necessary to restart the scanner 210 once. For this reason, the scanner activation check program 530b executes the restart of the OS 510, and causes the monitor 110 to display a message to turn off the scanner 210 and turn it on again. As a result, the user turns off / on the power of the scanner 210 and restarts the scanner 210. Thereby, for example, it is possible to eliminate the occurrence of an error other than the process waiting state of the TWAIN driver 520.

(Modification)
The present invention is not limited to the embodiments described above, and various modifications such as the following are possible.
(1) In the first embodiment, the scanner activation check program 530 is executed by the processing device (PC) in which the OS 510 is installed, and the recovery processing unit 534a causes the restart processing unit 512 of the OS 510 to restart. However, another recovery processing unit 534c having the function of the restart processing unit 512 may perform the restart. That is, the new scanner activation check program 530 causes the recovery processing unit 534c to restart when the OS 510 activates the WIA module 514 and the TWAIN driver 520 and the detection unit 532 detects an error in the TWAIN driver 520. May be.

(2) In the second embodiment, the power of the scanner 210 is manually turned OFF / ON. However, the restoration processing unit 534a may be configured to transmit a restart command to the scanner 210. At this time, the restart processing unit 512 may display an instruction message image (FIG. 7) and transmit a restart command after the “Restart Now” button is pressed. Further, the restart command may be transmitted without displaying the instruction message image (FIG. 7).

(3) In each of the above embodiments, the detection unit 532 is activated following the activation of the WIA module 514 and the TWAIN driver 518 by storing the system activation batch 540 in the startup folder. However, after the OS 510 is started, other application software different from the application software 550 may be started, and then the scanner start check program 530b may be started. In this case, other application software does not use the WIA module 514 or the TWAIN driver 518.
(4) In each of the above embodiments, the scanner 210 is used as a peripheral device. However, other peripheral devices such as a digital camera compatible with the WIA module 514 and the TWAIN driver 518 may be used. Further, it may be a peripheral device not supported by the WIA module 514 or the TWAIN driver 518, for example, a printer.
