  The present invention provides a communication device that can be connected to another device so that they can communicate with each other via a communication line, a management device that manages a device via a network, and a communication between the management device and a managed device. The present invention relates to a management system including an intermediary device.

In a service configuration in which network devices connected to the user environment are managed from a remote location such as a service provider, an intermediary device is installed in the user environment, and the mediator device acquires device information of the devices on the network and provides the service provider There is known a system that effectively transmits data.
The intermediary device as described above is responsible for connecting to multiple network devices connected to the user's private network and periodically acquiring the device information necessary for management, and notifying the acquired information to the service provider. Remotely managed by the service provider.

  In addition, the intermediary device as described above often has a function of an SNMP (Simple Network Management Protocol) manager, and cooperates with various devices to be managed having an SNMP agent function. Since the MIB (Management Information Base) information stored in these devices includes the device information of the device, it is possible to grasp the device information of the devices on the network by acquiring the MIB. is there.

However, conventionally, there have been the following problems as a method for dealing with an increase in the number of managed devices.
The SNMP manager only acquires standard MIBs including public information that does not depend on the vendor of the device manufacturer. And, for private MIBs for which vendors determine their own specifications, generally only customers who use the devices can grasp the private MIBs, and for the devices of other vendors, the specifications of the private MIBs are not disclosed. It has been difficult to incorporate a mechanism for acquiring a private MIB into a product in advance.

  Therefore, conventionally, in a multi-vendor network environment, standard device information that can be commonly acquired from devices of multiple vendors based on acquisition information for acquiring device information and extended device information that can be acquired for each vendor's device There is a communication device (see, for example, Patent Document 1) that acquires device information including, manages the device information in association with each vendor, and transmits the device information to the acquisition device.

However, the device information acquired by the above-described conventional communication device is non-uniform with different data formats and counting units depending on the model of the vendor and model, and such non-uniform device information is There was a problem that it was difficult to use in an integrated manner even if they were compiled.
For example, an example in which the remaining toner value and the total color counter value in the image processing apparatus are different for each vendor device of the image processing apparatus will be described below.

(Toner level)
Company A: Recording from 100 to 0 in increments of 1 B Company: Recording from 1 to 0 in increments of 0.01 Recording company C: Qualitative values in increments of 1/4 (MAX, near end 1, near end 2) , End) (total color counter value)
Company A: There is a standard MIB indicating the total color counter value.
Company B: Records the sum of the standard MIB of the total color printer counter value and the private MIB of the total color scanner counter value.
Company C: Records the value obtained by subtracting the private MIB of the total monochrome counter value from the standard MIB of the total counter value.

In recent years, services that propose optimal placement of managed devices in the MPS business have become active, and more detailed information included in private MIBs can be obtained from other companies' machines in order to compare with information that can be obtained from own machines. In addition, vendor-independent data is required.
The present invention has been made in view of the above points, and device information in which various data formats and counting units are different depending on the manufacturer and model from a plurality of devices having different manufacturers and models connected on a communication line. It is intended to be able to output information in a unified format specified in advance.

  In order to achieve the above object, the present invention achieves the above-mentioned object, in a communication apparatus, model identification information acquisition means for acquiring model identification information of the device from the device on the communication line, model identification information of the device, and device information acquired from the device The first storage means for storing the information in association with the access method to the device, and the device that has acquired the model identification information by the model identification information acquisition means is accessed by the access method corresponding to the model identification information. Refer to device information acquisition means for acquiring device information from the device, and second storage means for storing the model identification information of the device and the rules for converting the device information acquired from the device into a predetermined format in association with each other. Then, the device information acquired by the device information acquisition unit is updated according to the rules corresponding to the device identification information of the device acquired by the model identification information acquisition unit. Is provided with a conversion means for converting into a predetermined format.

When the image processing apparatus 3 is configured as an image processing apparatus other than the image forming apparatus, an engine unit suitable for the function is provided instead of the image forming unit 51.

Next, data stored by the data center 2 and the intermediary device 1 for acquiring and managing device information from the image processing device 3 will be described.
First, FIG. 4 shows an example of the data type registration table.
This data type registration table is a table that defines what data is managed in the data center 2 and is stored in the data center 2 as indicated by reference numeral 70 in FIG. The contents are basically set by an engineer or the like according to the specifications of the management service to be provided by the data center 2. However, automatic generation is not prevented.

As shown in FIG. 4, the data type registration table registers the data type ID, the data type name, the data type, and the data of each item of the quantification rule or qualification rule in association with each other.
Among these, the data type ID is identification information of the data type managed in the data center 2. Note that various types of data are not necessarily stored in the image processing apparatus 3 to be managed as they are. Any information obtained by performing some conversion (processing) on the device information stored in the image processing apparatus 3 may be used.
The data type name is the name of data indicated by the data type ID. For example, the data type ID “000001” is data of the data type name “total counter”.

The data type indicates the data type when data is stored. For example, the data type of the data type name “total counter” is “Counter32”.
The quantification rule or the qualification rule indicates the content represented by the data value of the corresponding item. This means what kind of data the device information stored in various shapes and items depending on the model of the image processing apparatus should be finally processed. That is, it is information that defines the format of data to be finally obtained. Note that in the sense of aligning data with a predetermined scale, such data conversion or processing can be referred to as “normalization” of data.

  For example, for the total count value with the data type ID “000001”, the sum of the total number of black-and-white and color prints of the printer and the total number of black-and-white and color readings of the scanner is 1 per print output or scan. It is stipulated that data should be counted as a counted value.

For the total color count value with the data type ID “000002”, the total number of color prints of the printer and the total number of color readings of the scanner are totaled as a value counted as one count in one print output or scan. It is stipulated.
For the toner remaining amount (magenta) with the data type ID “001010”, it is defined that the remaining amount of magenta toner should be tabulated as a ratio (percentage) to the maximum value.

Next, FIG. 5 shows an example of the conversion information table.
The conversion information table may be stored in any location as long as the conversion information table is stored in a location that can be referred to from the mediation apparatus 1. Even if it is stored locally in the intermediary device 1, it may be stored in the data center 2 as shown by reference numeral 71 in FIG. You may memorize | store in the memory | storage means provided in the other apparatus.

  Further, the contents of the conversion information table are basically registered in the table by referring to the data type registration table shown in FIG. 4 by the customer engineer 7 who knows the specifications of the image processing apparatus 3 to be managed. The method of obtaining the parameters being registered is registered. Formulas and conversions that indicate which model information stored in the image processing device can be converted (processed) and how data can be obtained according to the quantification rules or qualification rules registered in the data type registration table You can register the conditions. Note that the contents of the conversion information table can be automatically generated.

In this conversion information table, as shown in FIG. 5, data of each item of data type ID, vendor ID, model ID, and conversion information is registered in association with each other.
Among these, the data type ID is the same as the data type ID in the data type registration table shown in FIG.

The vendor ID is identification information indicating a company that manufactures the image processing apparatus. In order to identify the model, the model ID is basically sufficient, but since the model name may coincide by chance at different manufacturers, the vendor ID is also used here for identifying the model.
The model ID is identification information indicating the model of the image processing apparatus. Even if the hardware is the same model, if the device information storage mode or tabulation mode has changed due to firmware update, a different model ID may be assigned to each firmware version.
The above vendor ID and model ID are model identification information.

  The conversion information is information that defines how to convert the device information to be acquired in order to calculate the data indicated by the data type ID and the acquired device information. In the example of FIG. 5, it is indicated that the device information of the corresponding ID should be acquired using the data ID registered in the access information table shown in FIG. In addition, the rules for how to convert the acquired device information are shown by the formula of the four arithmetic operations.

Since device information stored for each model of the image processing apparatus is different, conversion information suitable for the corresponding model is prepared for each model.
Further, the conversion information provides a conversion rule for the device information and searches the access information table shown in FIG. 6 to obtain an access method to the device information through which device information is necessary. It can be said that it provides key information.

In the example of FIG. 5, for the total counter value with the data type ID “000001”, the device information with the data ID “A000000XXXX” and the device information with the data ID “A000000YYYY” are acquired in the ModelXXX manufactured by company A. It is specified that these should be added. On the other hand, AAA-BBB made by company B
In the case of Model, it is specified that three pieces of device information with data IDs “B003333XXXX”, “B003333YYYY”, and “B003333ZZZZ” should be acquired and added.
In addition to the four arithmetic operations as shown in FIG. 5, it is also possible to define a rule for converting qualitative data such as “full” or “near end” into quantitative data. Conversely, it is possible to define rules for converting quantitative data into qualitative data.

Next, FIG. 6 shows an example of the access information table.
This access information table only needs to be held in a location that can be referred to from the mediation apparatus 1. However, since it is a table for registering community names used for purposes such as passwords in SNMP and authentication passwords themselves, it is necessary to prevent access from third parties. In that sense, it is not preferable that the data center 2 aggregates information from each intermediary device 1.

  The contents of the access information table are basically acquired from the image processing apparatus 3 by the user 6 who knows the specifications of the image processing apparatus 3 to be managed and the authentication information for accessing the image processing apparatus 3. The device information that needs to be registered is registered. The acquisition method can be indicated by which OID (object ID) data should be accessed among the data held by the image processing apparatus 3 in the MIB format. In addition, community name and V2.2c. If additional information such as extended information for 3 is required, it is also registered. Further, it is not hindered to automatically generate the contents of the access information table.

As shown in FIG. 6, the access information table includes a data ID, a vendor ID, a model ID, an OID, a community name, and V2.2c. The data of each item of the extended information for 3 is registered correspondingly.
Of these, the data ID is an ID for identifying an item of device information. Even if device information represents the same content or exactly the same content, if the model of the image processing apparatus 3 is different, the storage position may be different. Register.

The vendor ID and model ID are the same as those in the conversion information table of FIG.
The OID is information indicating in which part of the data held in the MIB format in the corresponding model the corresponding device information exists. That is, it is understood that desired device information can be obtained by accessing data having the OID using SNMP.

The community name is a community name used when accessing device information of the corresponding model using SNMP.
V2.2c. The extended information for 3 is extended information such as an authentication password used when accessing device information of the corresponding model using SNMP. If extended information is unnecessary, “None” may be registered.

Based on the above information, for example, when it is desired to acquire device information with the data ID “A000000XXXX”, SNMP is used to access data having an OID of “1.3.6.1.2.1.2.1...” Using “public” as the community name. You can see that The vendor ID and model ID are for reference in this table, and may not be registered.
In addition, even if information on the same device information is registered in duplicate in the access information table by giving a plurality of data IDs, the data ID is indicated from the data ID included in the conversion information of the conversion information table. There is no particular problem if a device information acquisition method is obtained.

Next, FIG. 7 shows an example of the data ID management table.
This data ID management table can be stored in the data center 2 and updated based on information notified from each mediation apparatus 1. This is for facilitating the creation of the access information table in the intermediary device 1 by sharing a portion of the access information table that can be shared.

In this data ID management table, as shown in FIG. 7, data items of data ID, vendor ID, model ID, and OID are registered in association with each other. The significance of these items is the same as in the access information table.
The information in this range is information on the specifications of the image processing apparatus, and is not set individually by the user of the image processing apparatus, so it can be shared. On the other hand, it is useful information for acquiring individual device information.
The usage of this data ID management table will be described later.

Next, FIG. 8 shows an example of the converted device information table.
This converted device information table is a table for managing device information stored in the data center 2 and notified from each intermediary device 1. The device information stored here is, of course, information converted into a predetermined format according to the conversion information registered in the conversion information table.

In the converted device information table, as shown in FIG. 8, a customer ID, a device ID, a data type ID, a data value, and an acquisition date and time are registered.
Among these, the customer ID is identification information for specifying the customer environment shown in FIG. Here, it shows which customer's device information the device information is.

The device ID is identification information for specifying an individual device. Here, the image processing apparatus from which the device information is acquired is shown.
The data type ID is the same as that in the data type registration table of FIG. Here, the type of data acquired is shown.
The data value is a value of the acquired device information after conversion.
The acquisition date / time indicates the date / time when the device information is acquired.

  When the data center 2 is notified of the device information of the image processing device 3 from the mediation device 1, the data center 2 registers the information related to the notification in the converted device information table. In FIG. 2, there is a converted device information table for each customer environment, but FIG. 8 shows an example in which these tables are combined into one table.

Next, a process in which the mediation device 1 acquires device information of the image processing device 3 and transmits it to the data center 2 will be described.
First, a process when the contents of the access information table and the conversion information table are set from the PC 5 by the user 6 or the CE 7 to the mediation apparatus 1 will be described.
FIG. 9 is a sequence diagram illustrating a first example of processing in which the mediation device 1 acquires device information of the image processing device 3 and transmits the device information to the data center 2.

When there is an input for setting conversion information to be registered in the conversion information table shown in FIG. 5 from the PC 5 (S11), the intermediary device 1 registers this in the conversion information table and transmits a response to the PC 5 (S12).
When there is an input for setting access information to be registered in the access information table shown in FIG. 6 from the PC 5 (S13), this is registered in the access information table and a response is transmitted to the PC 5 (S14).

  These processes can be repeated any number of times in no particular order. Further, the intermediary device 1 transmits the conversion information registered in the conversion information table and the access information registered in the access information table to the data center 2 at an appropriate timing, and registers them in the conversion information table and access information table of the data center 2. (S15). The data to be transmitted here is data excluding customer-specific information such as community names and extended information shown in FIG.

Upon receiving this, the data center 2 registers in the conversion information table and the data ID management table shown in FIG. 7 and returns a receipt response (S16). The information registered here can be referred to from an arbitrary intermediary device 1 in the process of FIG. 10 described later.
In this way, the information set for a certain intermediary device 1 is transmitted to the data center 2 to be registered, and can be referred to from other intermediary devices 1, so that the data ID management table is stored in each intermediary device 1. It is possible to substantially reduce the effort of sharing and creating contents. Of course, such sharing may be performed between the mediation apparatuses 1 in different customer environments.

  Further, the mediation device 1 should acquire device information from the image processing device 3 and transmit it to the data center 2 by operating the input device 24, detecting arrival of a predetermined time by the timer 36, detecting a management command from the data center 2, and the like. When this is detected, the data type ID of the data to be transmitted and the acquisition destination image processing device are specified (S21), and the processing from step S22 onward for data transmission is started. This process can be started at an arbitrary timing as long as necessary data is registered in the conversion information table and the access information table. The image processing apparatus may be specified by specifying the device ID, the address, and the like to such an extent that the image processing apparatus 3 can be accessed.

First, the mediation apparatus 1 requests the specified image processing apparatus 3 to acquire the vendor ID and model ID of the image processing apparatus 3 (S22). Note that the vendor ID and model ID can usually be acquired by the standard MIB, and therefore it is not necessary to refer to the access information table for this request.
On the other hand, the image processing apparatus 3 returns a vendor ID and a model ID, and the mediation apparatus 1 receives this (S23). The received vendor ID and model ID are stored, for example, in the memory device 22 of FIG.

Next, the intermediary device 1 refers to the conversion information table and specifies the data ID of the device information to be acquired in order to obtain the data to be transmitted to the data center 2 based on the vendor ID and model ID acquired in step S23. (S24). Specifically, the conversion information table may be searched using the data type ID specified in step S21 and the vendor ID and model ID acquired in step S23 as keys, and the data ID included in the corresponding conversion information may be acquired.
Next, the intermediary device 1 refers to the access information table and identifies a method for acquiring device information having the data ID identified in step S24 (S25). If multiple pieces of device information are required, the acquisition method is specified for all of them. This can be done by simply searching the access information table using the data ID as a key.

Next, the mediating apparatus 1 accesses the image processing apparatus 3 according to the acquisition method specified in step S25, and requests device information (S26). Upon receiving this access, the image processing device 3 returns device information, and the mediation device 1 receives this (S27).
Next, the intermediary device 1 converts the acquired device information according to the conversion rule registered in the conversion information table (S28). This conversion rule is indicated by the conversion information referred to in step S24.

  Thereafter, the intermediary device 1 notifies the data center 2 of the converted device information (S29). The data center 2 registers this information in the converted device information table shown in FIG. 8, and returns a receipt response (S30). In step S29, the intermediary device 1 may transmit other information to be registered in the converted device information table, such as the customer ID, device ID, data type ID, and acquisition date.

In this way, the data center 2 can acquire and store the device information of the image processing apparatus 3 to be managed in a state converted into a predetermined format. In other words, even when the model of the image processing apparatus 3 to be managed is different and device information in which various data formats and counting units differ depending on the manufacturer or model is stored, a unified format specified in advance is stored. It can be obtained as information.
Therefore, the collected information can be compared based on a unified standard, and efficient management can be performed.

Next, processing when the mediation apparatus 1 acquires access information and conversion information from the data center 2 will be described.
FIG. 10 is a sequence diagram illustrating a second example of processing in which the mediation device 1 acquires device information of the image processing device 3 and transmits the device information to the data center 2.

  In this process, as in the case of step S21 in FIG. 9, when the mediating apparatus 1 detects that the device information is acquired from the image processing apparatus 3 and should be transmitted to the data center 2, the data type ID of the data to be transmitted And the acquisition destination image processing apparatus is specified (S41), and the process after step S42 for data transmission is started.

  First, the mediation apparatus 1 requests the specified image processing apparatus 3 to acquire the vendor ID and model ID of the image processing apparatus 3 (S42). On the other hand, the image processing apparatus 3 returns a vendor ID and a model ID, and the mediation apparatus 1 receives this (S43). This part is also the same as steps S22 and S23 in FIG.

  Next, the intermediary device 1 transmits the data type ID specified in step S41 and the vendor ID and model ID acquired in step S43 to the data center 2, and requests conversion information corresponding to these (S44). . On the other hand, the data center 2 returns conversion information corresponding to each ID received with reference to its own conversion information table, and the mediation apparatus 1 receives this (S45). In the conversion information table of the data center 2, it is assumed that the conversion information set in each mediating apparatus 1 is collected by the processing in step S15 in FIG.

  Next, the intermediary device 1 transmits to the data center 2 the data ID of the device information determined to be acquired based on the conversion information received in step S45, and requests access information corresponding to these (S46). On the other hand, the data center 2 returns the access information corresponding to the received data ID with reference to its own data ID management table, and the mediation apparatus 1 receives this (S47). In the data ID management table of the data center 2, it is assumed that the access information set in each intermediary device 1 is collected by the processing in step S15 in FIG.

  Thereafter, the intermediary device 1 acquires any authentication information necessary for accessing the image processing device 3 in accordance with the acquired access information (S48). This is because the access information acquired from the data center 2 does not include community names or extended information. This authentication information can be acquired from an authentication information management unit (not shown) that manages the authentication information of the image processing apparatus 3 in the mediation apparatus 1.

  Next, according to the authentication information acquisition method specified by the access information acquired in step S47, the mediating apparatus 1 accesses the image processing apparatus 3 using the authentication information acquired in step S48 and requests device information (S49). ). Upon receiving this access, the image processing device 3 returns device information, and the mediation device 1 receives this (S50).

Next, the mediating apparatus 1 converts the acquired device information according to the conversion rule specified by the conversion information acquired in step S45 (S51).
Thereafter, the intermediary device 1 notifies the data center 2 of the converted device information (S52). The data center 2 registers this information in the converted device information table shown in FIG. 8, and returns a receipt response (S53). These processes are the same as steps S29 and S30 in FIG.

In this way, in the data center 2, as in the case of FIG. 9, the device information of the image processing apparatus 3 to be managed can be acquired and stored in a state converted into a predetermined format.
Note that the contents of the conversion information table and the data ID management table provided in the data center 2 are not necessarily created based on the information transmitted from the mediation apparatus 1. You may create based on the information which the operator of the data center 2 input.

Although the description of the embodiment has been completed above, in the present invention, the specific configuration of each unit, the content of processing, the data format, and the like are not limited to those described in the embodiment.
For example, in steps S44 and S46 in FIG. 10, the mediating apparatus 1 does not request conversion information and access information from the data center 2, but requests transmission of the conversion information table and the data ID management table itself. Also good. Then, these tables may be downloaded and stored locally (the data ID management table is changed to an access information table), and thereafter the same processing as in FIG. 9 may be performed.

Further, it is not necessary to directly acquire model identification information such as a vendor ID and model ID from the target image processing apparatus from which device information is acquired. For example, if a vendor ID or model ID is registered in the list of managed devices in association with the device ID, the model identification information of the desired device may be acquired from the list.
Further, in the above-described embodiment, the case where the mediation devices 1a to 1c are image processing devices as devices for acquiring device information has been described. However, in general devices such as communication devices such as facsimile devices and information processing devices such as personal computers. Can be carried out in the same manner as described above.
Moreover, it is needless to say that the configurations of the embodiment and the modified examples described above can be arbitrarily combined and implemented as long as they do not contradict each other.
