Description

  The present invention relates to various CPU built-in devices in which a CPU for executing software stored in a storage unit is incorporated and the software is upgraded.

  In the CPU built-in device, for example, when a bug is found in the software executed by the CPU or when a new function needs to be added, an old version is changed to a new version in order to change or add a program. A so-called version upgrade is performed.

  This version upgrade is performed by rewriting the software in a storage unit such as a nonvolatile memory in which software executed by the CPU is written.

  There are cases where a production line is constituted by a plurality of such CPU built-in devices. For example, in a manufacturing factory for packed foods, a series of production lines are configured by connecting a weighing device, a packaging machine, a metal detector, a weight sorter, a boxing device, a conveying device, etc., which are CPU built-in devices. .

  In such a production line, according to the flow timing of the article, by performing appropriate processing so that each device does not contradict each other, efficient production becomes possible, but various causes, for example, There may be a problem in operation due to a contradiction in operation between devices due to software upgrade, a bug existing in the upgraded software, or a conflict between setting items of each device.

  When such a failure occurs, it takes a lot of labor and time to examine various factors one by one and to determine the cause of the failure.

  Therefore, the Applicant acquires the software version information of each device when such an operational failure occurs, determines whether the software is compatible between the devices based on the version information, and operates. Has proposed a technique that makes it possible to ascertain whether or not the above problem is caused by incompatibility of software between apparatuses (see Patent Document 1).

JP2007-276867A

  In the above-mentioned Patent Document 1, when an operation failure occurs, it is possible to grasp whether the cause is caused by incompatibility between software between devices, but the software is upgraded. In such a case, when a malfunction occurs due to a bug of the upgraded software itself, it is not easy to grasp the cause of the malfunction.

  In general, manufacturers of CPU built-in devices, when upgrading software, verify the operation of whether the upgraded software achieves the target function, but the conditions that the programmer does not assume In some cases, there is a bug in the software, and a malfunction may occur when the user actually uses the CPU built-in device.

  In such a case, if information on which items may have bugs in the software related to the items among the plurality of upgraded items can be obtained, the cause of the malfunction in the operation can be easily determined.

  The present invention has been made in view of the above points, and in the case where a malfunction in the CPU built-in device occurs, the software related to which item among a plurality of upgraded items It is an object of the present invention to obtain information on whether there is a possibility of causing the problem.

  In order to solve the above problems, the present invention is configured as follows.

  (1) A CPU built-in device according to the present invention is a CPU built-in device in which a CPU for executing software is built-in and the software is upgraded, and shows an upgrade item and an execution status of software related to the upgrade item. Upgrade information output means for outputting the included upgrade information is provided.

  Here, the CPU built-in device refers to various devices in which the software is upgraded and the software is upgraded, for example, various devices such as a weighing device, a packaging device, an inspection device, and a boxing device. Say.

  The version upgrade item refers to an item upgraded in the new version software with respect to the old version software, for example, a newly added item, an item in which a bug is corrected, or the like. The old version of the software is preferably the previous version of the new version of the software, but may be an earlier version of the software.

  The upgrade information output means may output the upgrade information to an external device such as a display device or a printer, or may include a display unit, a printing unit, etc., and display and print the upgrade information. It may output at least one of output and audio output.

The means may switch the display on the display unit to an identification display that can identify the upgrade item whose operation has been verified and the other upgrade item based on the designation by the designation input unit. .

  The identification display only needs to be a display that can identify a version-up item for which operation verification has been confirmed and other version-up items. For example, the display area of a version-up item for which operation verification has been confirmed and other version-up items The display area may have different gradation levels, hues, brightness, or the like.

  According to this embodiment, when it is determined that the number of executions of the software related to the upgraded item has reached a sufficient number for verifying the operation, the designated version is designated by designating the upgraded item by the designation input unit. Since the display is switched to a display that can identify the upgrade item and other upgrade items, it is possible to identify at a glance the upgrade item that has been verified and the other upgrade item that has not been verified.

  (4) In the embodiment of the above (3), the upgrade information output means includes a cancellation input unit that inputs the cancellation of the specified upgrade item that has been specified by the specified input unit and whose operation has been verified. May cancel the verification of the operation verification based on the cancellation by the cancellation input unit, and may return the identification display on the display unit to the original display.

  According to this embodiment, since the verification of the operation verification can be canceled, for example, in the manufacturer of the CPU built-in device, after verifying the operation of the upgraded item, the verification check is canceled and again The user of the CPU built-in device can verify the operation.

Based on the signals from the weight sorter 3, the metal detector 4, and the X-ray foreign matter detection device 5, the sorting device 6 is a defective product for packaging that is outside the allowable weight range and that has been detected to contain metal or foreign matter. As described above, while being removed from the production line as described above, a packaged product that is within the allowable weight range and that is free of metal or foreign matter is supplied to the downstream boxing device 7 as a good product.

   FIG. 2 is a block diagram showing a schematic configuration of the combination weigher 1 of FIG.

  The combination scale 1 of this embodiment inputs a scale main body 8, a CPU 9 for controlling each part, a storage part 10, a communication interface part 11 for communicating with an external device such as a packaging machine 2, and operating parameters. An input unit 12 and a display unit 13 for displaying a verification screen, which will be described later, are provided. In this embodiment, the input unit 12 and the display unit 13 are configured by a touch panel 17, which will be described later.

  The scale main body 8 is controlled by the CPU 9, and is a feeder that transports articles to be weighed, a supply hopper that stores articles supplied by the feeder, and a weighing that measures articles supplied via the supply hopper. A structure (not shown) such as a hopper and a collecting chute for discharging the weighed articles to the packaging machine 2 is provided.

  The storage unit 10 stores control software 15 for controlling the balance body 8 and the like, and operation parameters (target weight, operation speed, etc.) required for the weighing operation input via the input unit 12. Is stored. The operating parameters can be displayed on the display unit 13 and checked by the operator.

  The CPU 9 controls each part of the scale body 8 based on the control software 15 and operation parameters stored in the storage unit 10, performs combination weighing of articles, and sends articles within a predetermined weight range via the collective chute. Then, it is discharged intermittently to the packaging machine 2 in FIG. The storage unit 10 stores the control software 15 as described above. The software 15 is an upgrade of the old software, and the storage unit 10 has a later-described version upgrade related to the upgrade. Information 16 is also stored.

  In this embodiment, when an operational problem occurs in the combination weigher 1, it is possible to obtain information on which item of software that has been upgraded is likely to have the cause among the upgraded items. In order to achieve this, it is configured as follows.

  That is, in this embodiment, the upgrade information output means 14 for displaying the upgrade information including the upgrade item and the number of times of execution of the software related to the upgrade item is provided. The CPU 9, the storage unit 10, and the display unit 13 are provided.

  The upgrade information output means 14 displays the upgrade information including the upgrade item and the number of times of execution of the software related to the upgrade item on the display unit 13 as an upgrade verification screen.

  FIG. 3 is an example of an upgrade verification screen displayed on the touch panel 17 constituting the input unit 12 and the display unit 13 described above.

  This verification screen can be called by, for example, selecting from the menu screen. This verification screen includes a date / time display area 18 for displaying the date and time, a version number display area 19 for the new version of software 15 currently being executed, and an old version number display area 20 for the old version of software. When there is a message that cannot be displayed on the screen, the display data movement cursor touch type key switches 21 and 22 for shifting the display data up and down and the upgraded item display area 23 for displaying the upgraded item are displayed. An execution count display area 24 for displaying the number of executions of software related to the upgrade item for each upgrade item, a verification check touch key switch 25 provided for each upgrade item, and a verification check “set” touch key Switch 26 and verification confirmation “clear” touch A key switch 27, and a "return" touch-type key switch 28 for return to the previous screen, calling this verification screen.

  In the version number display area 19 and the old version number display area 20 of the verification screen, “Ver 2.30”, which is the version number of the software 15 currently being executed, and the version number of the previous previous version “ Ver2.23 "is displayed. The method of assigning the version number is arbitrary, but in general, it is represented by numbers up to the second decimal place. The first place indicates a large version upgrade, the 0.1 place indicates a small version upgrade, and 0 The place of .01 indicates a very small version upgrade such as bug fixes.

  In this embodiment, there are six items from the first version to the sixth item that have been upgraded from the previous version by the display of the version upgrade item display area 23, and the first to third items that have been upgraded. Is an optional function of the collective chute sorting operations (A) to (C) for sorting and discharging articles according to the type of the packaging machine 2, and the upgraded fourth item is a personal computer (PC) The fifth item that has been upgraded is the addition of an operation state display message, for example, when waiting until a discharge command signal from the packaging machine 2 is input, A display message to that effect is added, and the sixth item that has been upgraded is the addition of a new error message.

  In the execution number display area 24 provided for each version upgrade item, the number of software executions related to the item is displayed for each version upgrade item. In FIG. 3, all “0” s are displayed. This indicates that the software related to is not yet executed.

  In this embodiment, when the above-described CPU 9 executes software related to the upgrade item, the CPU 9 counts the number of executions with a built-in counter as will be described later, and displays it in the execution number display area 24 of the upgrade item.

  The operator looks at the number of executions displayed in the execution number display area 24 for each version upgrade item, determines whether the number of executions sufficient for verifying the operation of the software related to the version upgrade item has been reached, When it is determined that the sufficient number of executions has been reached, the verification check operation can be performed on the version upgrade item, assuming that the verification of the operation has been confirmed. This verification confirmation operation is performed by designating and inputting the upgrade item for which the verification of the operation has been confirmed, touching the verification confirmation touch type key switch 25 of the verified upgrade item, The touch-type key switch 26 is touched. As a result, the verification of the operation is confirmed for the version upgrade item, and the display is switched to the verification confirmation screen. The verification confirmation touch type key switch 25 and the verification confirmation “set” touch type key switch 26 constitute a designation input unit for designating and inputting a version upgrade item whose operation has been verified.

  FIG. 4 shows an example of the verification confirmation screen after the verification confirmation operation is performed, and parts corresponding to those in FIG. FIG. 4 shows an example of a screen on which the verification of the operations of the first to fifth five upgrade items is confirmed. That is, the first to fifth upgrade item display areas 23, the corresponding number of execution display areas 24, and the verification confirmation touch key switch 25 are switched to reverse display or light text display, and the verification of the operation is confirmed. In addition, the first to fifth upgrade items and the sixth upgrade item whose operation has not been verified yet are identified.

  The execution count display area 24 corresponding to each upgrade item display area 23 displays the execution count when the verification check operation is performed, and the first to third upgrade items are respectively shown. When the number of executions is “2341”, “1672”, “852”, a verification check operation is performed. For the fourth and fifth upgrade items, the number of executions is four digits “9999” or more. It can be seen that the verification check operation has been performed when “FFFF” is shown.

  In this embodiment, after an operation for verifying the upgrade item is performed, the verification can be cleared (cancelled) and the operation can be verified again. Accordingly, for example, after the verification check is performed in the manufacturer of the combination weigher 1, the operation can be verified again during actual use by the user.

  In order to clear the verification confirmation, the verification confirmation touch type key switch 25 corresponding to the version upgrade item verified is touched, and further, the verification confirmation “clear” touch type key switch 27 is operated. As a result, for the version upgrade item, the verification confirmation is cleared, and the original display is returned as in the verification screen of FIG. The verification check touch type key switch 25 and the verification check “clear” touch type key switch 27 constitute a cancel input unit for canceling the verification check of the upgrade item whose operation has been verified.

  FIG. 5 is a flowchart showing an example of processing of each execution program constituting the above-described upgraded software 15.

  The CPU 9 executes each execution program (1) to (m) of the combination weigher 1, for example, each execution program such as feeder control, supply hopper control and weighing hopper control (steps S1 to Sm), and further version An execution program that is software related to the first to third upgrade items described above is executed (step Sm + 1), and further, the execution program (n) of the combination weigher 1 is executed (step Sn). Further, among the upgraded items, an execution program, which is a bug correction software related to the above-mentioned fourth upgrade item, is executed (step Sn + 1). Software related to the 5th and 6th upgraded items among the upgraded items To run that execution program.

  In this way, the execution program related to the item not upgraded and the execution program related to the upgraded item are sequentially executed.

  Such an execution program is stored in the storage unit 10 composed of a nonvolatile memory whose stored contents do not disappear even when the power of the ROM or disk is turned off.

  FIG. 6 shows an example of execution processing of an execution program that is software related to the first to third upgrade items in FIG. 5 and a bug correction execution program that is software related to the fourth upgrade item. .

  In step S100, it is determined whether or not the execution program to be executed is an execution program related to the first upgrade item. If the execution program is an execution program related to the first upgrade item, the process proceeds to step S101. The execution program related to the first upgrade item is the execution program of “1. Option set chute distribution operation (A)” in FIG. In step S101, it is determined whether or not the verification completion flag is turned on for the first version upgrade item, and if the verification completion flag is not turned on, the first version upgrade is performed. The count value of the CPU built-in counter for counting the number of executions of the execution program related to the item is incremented by 1 and the process proceeds to step S103 (step S102). When the verification completion flag is ON, the verification check has been completed. The process proceeds to step S103 as it is.

  In step S103, a program related to the first upgrade item is executed. The number of executions which is the count value of the counter built in the CPU is displayed in the execution number display area 24 in FIG. The verification completion flag in step S101 is, for example, a flag that is turned on in step S306 in the flowchart of FIG. 7 described later, and is a flag that indicates that the verification check operation has been completed and set (stored).

  If it is determined in step S100 that the execution program is not related to the first upgrade item, the second upgrade item, that is, the execution program of “2. Option set chute distribution operation (B)” in FIG. (Step S104), if it is an execution program related to the second upgrade item, the same processing as in the case of the first upgrade item described above is performed (steps S105 to S107). If it is determined in S104 that the execution program is not related to the second upgrade item, it is determined whether or not the execution program is related to the third upgrade item (step S108). When it is an execution program involved, For the first version-up items mentioned and treated in the same manner (step S109 to S111). Thereafter, the execution program (n) of the combination weigher shown in FIG. 5 is executed.

  Thereafter, in step S200, whether or not the execution program to be executed is an execution program related to the fourth upgrade item, that is, an execution program of “4. Data transmission data (bug) to PC” in FIG. If it is an execution program related to the fourth upgrade item, it is determined whether or not the verification completion flag is turned on and the verification completion flag is turned on for the fourth upgrade item (step S201). When the verification completion flag is not ON, the count value of the CPU built-in counter for counting the number of executions of the execution program related to the fourth upgrade item is incremented by 1, and the process proceeds to step S203 (step S202). When the completion flag is ON, verification has been confirmed. It proceeds to step S203. In step S203, an execution program related to the fourth upgrade item is executed.

  Thereafter, the execution programs related to the fifth and sixth upgrade items are executed among the execution programs and the upgraded items of the combination weigher 1 (not shown).

  FIG. 7 is a flowchart showing a screen control process such as the verification screen of FIGS. 3 and 4 described above.

  In FIG. 7, steps S300 to S308 indicate screen control processing corresponding to the above-described verification confirmation operation, and steps S309 to S316 indicate screen control processing corresponding to the above-described verification confirmation clear (cancel) operation. ing.

  First, in step S300, it is determined whether or not the “SET” touch type key switch 26 on the verification screen in FIG. 3 has been touched and turned ON. n) is set (step S301), and the item number (a) of the upgrade item is set to the initial value (1) (step S302), and the verification confirmation touch key switch corresponding to the upgrade item of the item number is set. It is determined whether or not 25 is touched and turned on (step S303). If it is turned on, whether or not the number of executions of the program related to the upgrade item of the item number is greater than “0” is determined. Judgment is made (step S304). In this embodiment, if the number of executions of the program related to the upgrade item is greater than “0”, that is, once or more, the verification check operation is enabled. In step S304, when the number of executions of the program is greater than “0”, it is assumed that a verification check operation has been performed, and the display of the upgrade item of that item number is reversed, While switching to the above-described identification display of FIG. 4 for identifying other upgrade items, the verification completion flag of the upgrade item is turned ON (steps S305 and S306). Then, the number of item numbers is increased by 1 (step S307), and the above-described processing of steps S303 to S307 is repeated until the item number becomes a value obtained by adding 1 to the number of items of the upgrade item (step S308).

 If it is determined in step S300 that the “set” touch key switch 26 is not turned on, it is determined whether or not the “clear” touch key switch 27 in FIG. 3 is touched and turned on. Judgment is made (step S309). When ON, the number (n) of upgrade items is set (step S310), and the item number (a) of the upgrade item is set to the initial value (1) (step S311). It is determined whether or not the touch-type key switch 25 corresponding to the version upgrade item is touched and turned on (step S312). When the touch key switch 25 is on, the version upgrade item of the item number is verified. Assuming that the confirmation is cleared (cancelled), the inverted display (identification display) of the upgrade item is returned to the original normal display (step S313), and the verification completion flag of the upgrade item is turned OFF (step S314). ). Then, the number of item numbers is increased by 1 (step S315), and the above-described processing of steps S312 to S315 is repeated until the item number becomes a value obtained by adding 1 to the number of items of the upgrade item (step S316), and verification is performed. The verification confirmation of the item for which the confirmation touch type key switch 25 is ON is cleared (cancelled) to restore the verification.

  As described above, in this embodiment, since the upgraded item and the number of times of execution of the program that is the software related to the item are displayed, the version that has already been executed a sufficient number of times without causing any operational problems Upgrade items, upgrade items with insufficient execution count, or upgrade items that have not been executed at all, that is, upgrade items that have been verified for operation, versions that have insufficient verification of operation It is possible to determine an upgrade item or an upgrade item whose operation has not been verified.

  Thereby, in the case where an operation failure caused by a bug or the like occurs in the combination scale 1 after the version upgrade, based on the verification screen of FIG. 3 or the verification confirmation screen of FIG. For example, it is only necessary to investigate whether there is a cause of a malfunction in upgrade items other than the upgrade item that does not cause a malfunction because the upgrade has not been performed at all. Thus, operational defects can be solved efficiently.

  In addition, when an operation failure occurs, the user who uses the combination weigher 1 usually reports only the operation failure to the manufacturer of the combination weigher 1, and it takes time to investigate the cause. However, according to this embodiment, it is possible to report the status of the verification of the operation of the upgraded software, which makes it easier for the manufacturer to investigate the cause and reduce the time required to solve the problem. Is done.

  In the above-described embodiment, items updated with the current version of the software are displayed with respect to the previous version of the software. However, as another embodiment of the present invention, for example, the previous version of the software is displayed. On the other hand, an item upgraded with the current version of the software, or an item upgraded with the previous version of software with respect to the previous version of software may be displayed.

  In the above-described embodiment, when the operator determines that the number of executions sufficient for the verification of the operation has been reached, the verification confirmation touch key switch 25 and the “set” touch key switch 26 are operated to operate the operation. Although the display has been switched to the identification display that can identify the version-up item for which verification has been confirmed and other version-up items, as another embodiment of the present invention, a threshold is set for each version-up item in advance, and the number of executions is set to the threshold When it has been reached, the version upgrade item may be automatically switched to the identification display, assuming that the operation has been verified. Moreover, you may make it vary the said threshold value according to the operation time of a combination scale.

 The present invention is useful for various types of CPU built-in devices that are upgraded.
