However, if a plurality of devices are replaced at the same time, there is a risk that incorrect setting data will be set due to incorrect insertion of the USB memory or the like. For example, if device A and device A' exist as devices to be replaced, and device A is replaced with device B and device A' is replaced with device B', the setting data of device A is mistakenly transferred to device B'. setting, or setting data of device A' to device B by mistake.

In such a case, the device after replacement will be operated with incorrect setting data, and data may be transmitted to an unintended server.

An embodiment of the present invention will be described below. In this embodiment, even if incorrect setting data is set due to device replacement, by notifying the operator, etc., it is possible to prevent a situation in which incorrect setting data is used. A device 10 capable of

[First embodiment]
<Overall composition>
First, the overall configuration of a device 10 according to this embodiment will be described with reference to FIG. FIG. 1 is a diagram showing an example of the overall configuration of a device 10 according to the first embodiment.

As shown in FIG. 1, one or more peripheral devices 20 are wired or wirelessly connected to a device 10 according to the present embodiment. The peripheral device 20 is, for example, various sensors (for example, a pressure sensor, a vibration sensor, a temperature sensor, etc.), a PLC (Programmable Logic Controller) device, a CNC (Computerized Numerical Control) device, and the like.

The device 10 collects data from each peripheral device 20 connected to itself and transmits the data to the server 30 via a communication network such as the Internet. That is, the device 10 is a device or apparatus (for example, an embedded device such as an edge control device) that has at least a data collection function. The server 30 is a so-called cloud server, and provides services such as analysis and display of data collected from the device 10, for example. However, the server 30 does not have to be of the cloud type, and may be of the on-premise type, for example.

A PC 40 used for initial setting is connected to the device 10 by wire or wirelessly. Initial setting means setting setting data for the device 10 before the device 10 is installed and operated.

In addition, hereinafter, when distinguishing each of the plurality of peripheral devices 20, "peripheral device 20A",
They are expressed as “peripheral device 20B”, “peripheral device 20C”, and the like. Also, when distinguishing a plurality of devices 10 (for example, when distinguishing between a device 10 to be replaced and a device 10 after replacement), they are expressed as "device 10A", "device 10B", and the like.

<Overview of device replacement>
A case of replacing the device 10A with the device 10B will be described below.

As shown in FIG. 2, the device 10A according to the present embodiment stores the manufacturing number of each peripheral device 20 connected thereto and setting data as configuration information. When replacing the device 10A with the device 10B, after copying the configuration information stored in the device 10A to the USB memory, the device 10A is replaced with the device 10B, and the device 10B is connected to each peripheral device 20. do.

After that, the configuration information in the USB memory is saved in the device 10B. As a result, the setting data included in the configuration information is set in the device 10B. At this time, the device 10B checks whether or not the manufacturing number included in the configuration information matches the manufacturing number of each peripheral device 20 connected to itself. is incorrect.

As described above, in this embodiment, when the device 10 is replaced, it is checked whether or not the manufacturing numbers of the peripheral devices 20 connected to the device 10 match before and after the replacement. To prevent setting data from being set. This is because the same peripheral device 20 is generally connected to the device 10 before and after replacement.

As a result, for example, if the device 10A and the device 10C exist as the devices 10 to be replaced, and the device 10A is replaced with the device 10B and the device 10C is replaced with the device 10D, the setting data of the device 10A is mistakenly transferred to the device 10D. It is possible to prevent the setting data of the device 10C from being erroneously set to the device 10B. This is because the peripheral devices 20 connected to the device 10A and the peripheral devices 20 connected to the device 10C are different, and naturally have different manufacturing numbers. The manufacturing number is also called a unique manufacturing number, a serial number, or the like, and is information that uniquely identifies the peripheral device 20 .

Note that the use of the manufacturing number is an example, and any information that can uniquely identify the peripheral device 20 can be used instead of the manufacturing number. Such information includes, for example, a MAC (Media Access Control address) address, information determined to be unique within a system in which the device 10 is installed, such as a factory or plant.

Also, copying the configuration information to the USB memory when replacing the device 10 is an example, and any external recording medium can be used instead of the USB memory. Such an external recording medium includes, for example, an SD memory card.

<Hardware configuration>
Next, the hardware configuration of the device 10 according to this embodiment will be described with reference to FIG. FIG. 3 is a diagram showing an example of the hardware configuration of the device 10 according to the first embodiment.

As shown in FIG. 3, the device 10 according to this embodiment has an input device 101, a display device 102, an external I/F 103, a communication I/F 104, a processor 105, and a memory device . These pieces of hardware are communicably connected via a bus 107 .

The input device 101 is, for example, a physical button, a touch panel, or the like. The display device 102 is, for example, a display panel or the like. Note that the device 10 may not have at least one of the input device 101 and the display device 102 .

The external I/F 103 is an interface with the external recording medium 103a. Note that the external recording medium 103a includes, for example, a USB memory, an SD memory card, and the like.

The communication I/F 104 is an interface for the device 10 to communicate with the peripheral device 20, the server 30, the PC 40, and the like. The processor 105 is, for example, various arithmetic devices such as a CPU (Central Processing Unit) and an MPU (Micro-processing Unit). The memory device 106 is various storage devices such as flash memory. In particular, the memory device 106 includes a secure storage device having tamper resistance and the like.

By having the hardware configuration shown in FIG. 3, the device 10 according to the present embodiment can implement various processes described later. Note that the hardware configuration shown in FIG. 3 is an example, and the device 10 may have other hardware configurations. For example, device 10 may have multiple processors 105 and may have multiple memory devices 106 .

<Functional configuration>
Next, the functional configuration of the device 10 according to this embodiment will be described with reference to FIG. FIG. 4 is a diagram showing an example of the functional configuration of the device 10 according to the first embodiment.

As shown in FIG. 4, the device 10 according to this embodiment includes a setting unit 201, a peripheral device communication unit 202, an external input/output unit 203, a setting error check unit 204, a notification unit 205, and a server communication unit. 206. These units are realized, for example, by processing that one or more programs installed in the device 10 cause the processor 105 to execute.

The device 10 according to this embodiment also has a configuration information storage unit 207 . The configuration information storage unit 207 is realized by the memory device 106, for example.

The setting unit 201 saves configuration information in the configuration information storage unit 207 . For example, during initial setting, the setting unit 201 stores configuration information including setting data input from the PC 40 in the configuration information storage unit 207 . Further, for example, at the time of device replacement, the setting unit 201 stores the configuration information read from the USB memory by the external input/output unit 203 in the configuration information storage unit 207 .

The peripheral device communication unit 202 communicates with each peripheral device 20 connected to the device 10 and acquires the serial number of each peripheral device 20 .

The external input/output unit 203 copies configuration information stored in the configuration information storage unit 207 to the USB memory, and reads configuration information stored in the USB memory. For example, if the device 10 is a replacement target device, the external input/output unit 203 copies the configuration information stored in the configuration information storage unit 207 to the USB memory. On the other hand, for example, if the device 10 is a device after replacement, the external input/output unit 203 reads the configuration information stored in the USB memory.

A setting error check unit 204 checks whether or not the configuration information stored in the configuration information storage unit 207 is correct. That is, the setting error check unit 204 checks whether or not the serial number included in the configuration information stored in the configuration information storage unit 207 matches the serial number acquired by the peripheral device communication unit 202 .

If the result of the check by the setting error checker 204 indicates that the manufacturing numbers do not match, the notification unit 205 notifies that the setting data is incorrect. Any notification method may be used at this time. For example, characters, symbols, or the like indicating that the setting data is incorrect may be displayed on the display panel, or a flashing light, a buzzer sound, or the like may be output. good.

The server communication unit 206 communicates with the server 30 using setting data included in configuration information stored in the configuration information storage unit 207 . That is, the server communication unit 206 transmits data collected from each peripheral device 20 to the server 30 using the setting data.

The configuration information storage unit 207 stores configuration information. Note that the configuration information storage unit 207 is preferably realized by a secure storage device having tamper resistance and the like.

FIG. 5 shows an example of configuration information stored in the configuration information storage unit 207. As shown in FIG. As shown in FIG. 5, the configuration information consists of setting data and a manufacturing number. The setting data includes the connection destination address of the server 30, the user name and password for logging in to the server 30, the installation location of the device 10, the device name, and the like. On the other hand, the serial number is the serial number of each peripheral device 20 connected to the device 10 . In FIG. 5, a CNC device, a PLC device, a pressure sensor, a vibration sensor, and a temperature sensor are connected to the device 10 as peripheral equipment 20, and the respective serial numbers are "CN111111", "PL111112", "DN111113", Examples are shown that are "SN111114" and "ON111115".

In this way, the configuration information stored in the configuration information storage unit 207 mainly includes setting data including information for connecting to the server 30 and information on the device 10 itself, and information on the configuration data connected to the device 10 . It is configured with the manufacturing number of each peripheral device 20 .

<Flow of processing at initial setting>
The flow of processing when initializing the device 10 will be described below with reference to FIG. FIG. 6 is a flowchart showing an example of the flow of processing during initialization according to the first embodiment. It is assumed that the PC 40 is connected to the device 10 at the time of initial setting. It is also assumed that each peripheral device 20 is connected to the device 10 .

The setting unit 201 of the device 10 determines whether setting data has been input from the PC 40 (step S101). The PC 40 is installed with a program (for example, a program called an installation data generation tool or the like) for generating setting data and outputting it to the device 10 .

If it is determined in step S101 above that the setting data has not been input, the device 10 returns to step S101. That is, in this case, the device 10 waits for input of setting data.

On the other hand, if it is determined in step S101 that the setting data has been input, the peripheral device communication unit 202 of the device 10 acquires the serial number from each peripheral device 20 connected thereto (step S102). Note that, for example, when N peripheral devices 20 are connected to the device 10, the peripheral device communication unit 202 acquires the serial number from each of these N peripheral devices 20, and obtains N serial numbers. .

Then, the setting unit 201 of the device 10 saves information including the setting data input from the PC 40 and the serial number obtained in step S102 as configuration information in the configuration information storage unit 207 (step S103). ). Thereby, the configuration information including the setting data is set in the device 10, and the initial setting is completed.

<Flow of processing at the time of device replacement>
The flow of processing when replacing the device 10A with the device 10B will be described below with reference to FIG. FIG. 7 is a flowchart showing an example of the flow of processing during device replacement according to the first embodiment. The device 10A is the device to be replaced, and the device 10B is the post-replacement device.

First, the external input/output unit 203 of the device 10A copies the configuration information stored in the configuration information storage unit 207 to the USB memory (step S201). For example, the configuration information can be copied to the USB memory by the worker inserting the USB memory into the device 10A and performing a copy start operation. This completes preparations for exchanging the device 10A.

After completing preparations for replacing the device 10A, the operator turns off the power of the device 10A, disconnects it from each peripheral device 20, and then replaces the device 10A with the device 10B. Then, the operator or the like connects each peripheral device 20 to the device 10B, turns on the power of the device 10B, and inserts a USB memory into the device 10B.

The device 10B reads the configuration information stored in the USB memory by the external input/output unit 203, and stores the configuration information in the configuration information storage unit 207 by the setting unit 201 (step S202). As a result, the configuration information including the setting data is saved in the configuration information storage unit 207, and the setting data is set in the device 10B. Note that, for example, the configuration information can be read from the USB memory inserted in the device 10B by the operator performing a read start operation.

Next, the device 10B checks whether or not the setting data set in step S202 is incorrect (setting error check) (step S203).

≪Setting error check≫
Here, the flow of processing during the setting error check in step S203 will be described with reference to FIG. FIG. 8 is a flowchart showing an example of the flow of processing during setting error check according to the first embodiment.

The peripheral device communication unit 202 of the device 10B acquires the manufacturing number from each peripheral device 20 connected thereto (step S301).

Next, the setting error check unit 204 of the device 10B compares each serial number acquired in step S301 with each serial number included in the configuration information stored in the configuration information storage unit 207 (step S302).

Then, the setting error check unit 204 of the device 10B determines whether or not the comparison result in step S302 indicates that the serial numbers match each other (step S303). Here, the setting error check unit 204 checks that each manufacturing number acquired in step S301 and each manufacturing number included in the configuration information stored in the configuration information storage unit 207 match each other except for the order. If so, it is determined that the serial numbers match each other, and if not, it is determined that the serial numbers do not match each other.

A specific description will be given. Hereafter, each manufacturing number acquired in the above step S301 is referred to as "first manufacturing number group", and each manufacturing number included in the configuration information stored in the configuration information storage unit 207 is referred to as "second manufacturing number group". It says. Although the name "group" is used, the case where there is only one serial number is also included.

For example, assume that the first serial number group is as follows.

ON111115
CN111111
DN111113
SN111114
PL111112
On the other hand, assume that the second serial number group is as follows.

CN111111
PL111112
DN111113
SN111114
ON111115
In this case, since the first group of serial numbers and the second group of serial numbers match except for the order, it is determined that the respective serial numbers match each other.

Another specific example is given.

For example, assume that the first serial number group is as follows.

CN111120
DN111121
SN111122
On the other hand, assume that the second serial number group is the same as above. In this case, since the first group of serial numbers and the second group of serial numbers do not match, it is determined that the respective serial numbers do not match.

If it is determined in step S303 that the manufacturing numbers match each other, the device 10B ends the setting error check. On the other hand, if it is not determined in step S303 that the serial numbers match each other, the notification unit 205 of the device 10B notifies that the setting data is incorrect (step S304).

In this way, in the setting error check, each serial number included in the configuration information read from the USB memory matches each serial number acquired from each peripheral device 20 actually connected to the post-replacement device. If they do not match, it is notified that the setting data is incorrect. As a result, even if incorrect setting data (that is, setting data that should be set in another device 10) is set in the device 10 after replacement, the operator or the like can correct the error before the actual operation. can know. Therefore, it is possible to prevent a situation in which the replaced device 10 is operated with erroneous setting data due to operations such as resetting the setting data.

<Flow of processing when updating configuration information>
Here, for example, the peripheral device 20 connected to the device 10 may need to be replaced due to a failure of the peripheral device 20 or the like. In this case, the manufacturing number included in the configuration information stored in the configuration information storage unit 207 of the device 10 also needs to be updated. Therefore, the flow of processing when updating the configuration information will be described below with reference to FIG. FIG. 9 is a flowchart showing an example of the flow of processing when updating configuration information according to the first embodiment. In the following, it is assumed that a certain peripheral device 20 connected to a certain device 10 has been replaced.

First, the peripheral device communication unit 202 of the device 10 acquires the manufacturing number from each peripheral device 20 connected thereto (step S401). Note that this step is started, for example, when an operator or the like performs an update start operation.

Then, the setting unit 201 of the device 10 updates each manufacturing number included in the configuration information stored in the configuration information storage unit 207 with each manufacturing number acquired in step S401 (step S402). As a result, the manufacturing number included in the configuration information becomes the manufacturing number of each peripheral device 20 currently connected to the device 10 .

<Summary>
As described above, the device 10 according to the present embodiment holds configuration information composed of setting data and the serial number of each peripheral device 20 connected to itself. Then, when the device 10 is replaced, this configuration information is copied to an external recording medium such as a USB memory, and the device 10 after replacement has the serial number included in this configuration information and is connected to itself. It is checked whether or not the serial number of each peripheral device 20 matches except for the order. As a result, even if incorrect setting data is set in the device 10 after replacement, the operator or the like can be notified of the error. Therefore, for example, it is possible to prevent the device 10 from being operated with incorrect setting data.

<Modification>
Some modifications of this embodiment will be described below.

・Modification 1
In step S303 above, it is determined whether or not the first group of serial numbers and the second group of serial numbers match except for the order. It may be determined whether or not This is because, for example, depending on the type of peripheral device 20, it is necessary to connect the peripheral device 20 to the device 10 in a certain order.

・Modification 2
In the present embodiment, the configuration information stored in the USB memory is saved in the device 10 after replacement, but it does not necessarily have to be saved. For example, when a USB memory is inserted into the device 10 after connecting the replaced device 10 and each peripheral device 20, the manufacturing number obtained from each peripheral device 20 and the serial number stored in the USB memory are It may be checked whether or not the manufacturing number contained in the existing configuration information matches. In this case, the configuration information stored in the USB memory may be saved in the device 10 after replacement only when the check matches.

・Modification 3
As described above, execution of step S401 is started by, for example, an update start operation performed by an operator or the like. Therefore, if the operator forgets to start updating, the production number included in the configuration information will not be updated. On the other hand, it is rare that all the peripheral devices 20 connected to the device 10 are updated, and generally, some peripheral devices 20 (for example, about 1 to 2 peripheral devices 20) are replaced. often.

Therefore, even if the first serial number group and the second serial number group do not match in the above step S303, if some of the serial numbers match (for example, half or more If the manufacturing numbers match, etc.), the operator or the like may be notified in step S304 that there is a possibility that the configuration information has not been updated.

[Second embodiment]
Next, a second embodiment will be described. In the first embodiment, replacing one device 10 with another device 10 requires one USB memory. For this reason, for example, if there are N devices to be replaced, N USB memories are required, which complicates the management of the USB memories and may lead to mis-insertion of the USB memory into the device after replacement. .

Therefore, in this embodiment, configuration information of a plurality of devices to be replaced can be copied to one USB memory, and the correct configuration information from among the plurality of configuration information is stored in the device after replacement.

In addition, in this embodiment, differences from the first embodiment will be mainly described, and descriptions of components that are substantially the same as those of the first embodiment will be omitted.

<Functional configuration>
First, the functional configuration of the device 10 according to this embodiment will be described with reference to FIG. FIG. 10 is a diagram showing an example of the functional configuration of the device 10 according to the second embodiment.

As shown in FIG. 10, the device 10 according to this embodiment includes a setting unit 201, a peripheral communication unit 202, an external input/output unit 203, and a setting error check unit 204, as in the first embodiment. , a notification unit 205 , a server communication unit 206 , and a configuration information storage unit 207 .

In this embodiment, the external input/output unit 203 sequentially reads multiple pieces of configuration information stored in the USB memory. Also, the setting error check unit 204 checks whether the configuration information read from the USB memory by the external input/output unit 203 is correct (that is, the serial number included in the configuration information and the serial number acquired by the peripheral device communication unit 202). match). Then, the setting unit 201 saves the configuration information that has been checked to be correct by the setting error check unit 204 in the configuration information storage unit 207 . On the other hand, if it is not checked that the configuration information is correct for all of the plurality of configuration information stored in the USB memory, the notification unit 205 notifies that the setting data is incorrect.

<Flow of processing at the time of device replacement>
The flow of processing at the time of device replacement when there are a plurality of devices to be replaced will be described below with reference to FIG. FIG. 11 is a flowchart showing an example of the flow of processing during device replacement according to the second embodiment.

First, the external input/output unit 203 of each device 10 to be replaced copies the configuration information stored in the configuration information storage unit 207 to the USB memory (step S501). This is realized, for example, by the operator inserting the USB memory into the device to be replaced and then performing a copy start operation, which is repeated for each device to be replaced. For example, if there are three devices to be replaced, namely, "device 10A", "device 10A'", and "device 10A''", the worker or the like inserts a USB memory into the device 10A and performs a copy start operation. After the copy of the configuration information is completed, the USB memory is removed from the device 10A. Next, similarly, the operator or the like inserts the USB memory into the device 10A' and performs a copy start operation, and removes the USB memory from the device 10A' after the copy of the configuration information is completed. Subsequently, similarly, the operator or the like inserts the USB memory into the device 10A'' and performs a copy start operation, and removes the USB memory from the device 10A'' after the copy of the configuration information is completed. As a result, a plurality of pieces of configuration information (that is, configuration information of each of the plurality of devices to be replaced) are stored in the USB memory, and preparations for replacing each device to be replaced are completed.

After the replacement target device is ready to be replaced, the worker or the like turns off the power of the replacement target device and releases the connection with each peripheral device 20, and then replaces the replacement target device with the post-replacement device. . Then, the worker or the like connects each peripheral device 20 to the post-replacement device, turns on the power of the post-replacement device, and inserts the USB memory into the post-replacement device.

Each device 10, which is a post-replacement device, saves correct configuration information from among multiple pieces of configuration information (step S502). As a result, configuration information including setting data is saved in the configuration information storage unit 207 and the setting data is set in the device 10 . Note that this step may be started by, for example, inserting a USB memory into the device 10, or may be started by an operator or the like performing an operation.

<<Save configuration information>>
The flow of processing when the device 10, which is a post-replacement device, saves the correct configuration information from the plurality of configuration information in step S502 will be described below with reference to FIG. FIG. 12 is a flowchart showing an example of the flow of processing when configuration information is saved according to the second embodiment.

The peripheral device communication unit 202 of the device 10 acquires the manufacturing number from each peripheral device 20 connected thereto (step S601).

Next, the external input/output unit 203 of the device 10 reads one piece of configuration information from among multiple configurations stored in the USB memory (step S602).

Next, the setting error check unit 204 of the device 10 compares each serial number acquired in step S601 with each serial number included in the configuration information read in step S602 (step S603). .

Then, the setting error check unit 204 of the device 10 determines whether or not the comparison result in step S603 indicates that the serial numbers match each other (step S604). Note that the determination method in this step is the same as in step S303 in FIG.

If it is determined in step S604 that the manufacturing numbers match, the setting unit 201 of the device 10 stores the configuration information read in step S602 in the configuration information storage unit 207 (step S605). ). As a result, configuration information including setting data is saved in the configuration information storage unit 207 and the setting data is set in the device 10 .

On the other hand, if it is not determined in step S604 that the manufacturing numbers match each other, the external input/output unit 203 of the device 10 selects the following configuration among the plurality of configurations stored in the USB memory. It is determined whether or not there is information (that is, configuration information that has not yet been read) (step S606).

If it is determined in step S606 above that there is next configuration information, the device 10 returns to step S602 above. As a result, in step S602, the next configuration information is read by the external input/output unit 203 of the device 10, and the processes after step S603 are executed again.

On the other hand, if it is not determined in step S606 that there is the following configuration information, the notification unit 205 of the device 10 notifies that the setting data is incorrect (step S607). In this case, none of the configuration information stored in the USB memory is correct configuration information.

In this way, in the process of saving the configuration information, a plurality of pieces of configuration information stored in the USB memory are sequentially read, and the read configuration information is checked for setting errors. If the setting error check determines that the configuration information is correct, the configuration information is stored in the device 10. If the correct configuration information does not exist, it is notified that the setting data is incorrect. As a result, each post-replacement device can store only correct configuration information from among a plurality of pieces of configuration information in itself. It is possible to store a plurality of pieces of configuration information in the USB memory.

<Summary>
As described above, the device 10 according to the present embodiment can store only correct configuration information among multiple pieces of configuration information stored in the USB memory. Therefore, it is possible to store the configuration information of a plurality of devices to be replaced in one USB memory, which facilitates management of the USB memory. It is possible to prevent a situation in which the device 10 is operated with erroneous setting data. Modifications 1 and 3 described in the first embodiment are similarly applicable to this embodiment.

The present invention is not limited to the specifically disclosed embodiments described above, and various modifications, alterations, combinations with known techniques, etc. are possible without departing from the scope of the claims.
