  For example, devices such as PCs, printers, and fax machines are connected to an in-house network installed in an office or the like. For example, a printer connected to a network can be used from a plurality of terminals such as PCs. On the other hand, it is common for multiple printers to be connected to the network, and the user can set the printer to be used normally and change the settings of the printer to be used as necessary. Output is done.

  As described above, the devices connected to the network usually have various performances and installed environments. For example, when a printer is considered as an example of a network device, the printer performance includes a print speed and various print functions. The print speed indicates, for example, the print processing capability per unit time, and the print function includes various functions such as a color print function, a facsimile function, a staple function, a paper folding function, and a punch function.

  When network devices having different performances and functions are mixed and connected to the same network as described above, the performance of each device may not be fully utilized. For example, there is a case where only an amount of printing that is much less than the print processing capability of the printer is performed, or the function of the printer is not used effectively and the function is wasted. Alternatively, there may be a case where a large amount of print jobs are requested and the printer is overloaded even though the printing speed of the printer is relatively low.

  In such a case, if the performance and operating status of each printer can be managed and each printer can be operated in an appropriate operating status, printer resources can be used effectively. With regard to multiple devices connected to such a network, the technology that determines the devices to be processed after understanding the device operating status, the latest status, and the processing capability of the device, or the network device operating status As for the system to be managed, there are those described in the above patent documents.

It is not disclosed in prior art documents.

  The present invention has been made in view of the above circumstances, and analyzes whether or not the performance of the device is sufficiently exhibited based on the performance of the device connected to the network and its operating status. Efficient use of network devices by extracting the presence of devices that are in an unreasonable operating state that does not match the device performance and enabling the output of information that prompts the user to replace or add new devices It is an object of the present invention to provide a network device management apparatus and a management program that can be used.

In order to solve the above problem, a first technical means of the present invention is a management device that manages a management target device installed on a network, and the management device is a management target installed on the network. Device information acquisition means for acquiring performance information of the management target device from the device, operation information acquisition means for acquiring operation information of the management target device, and operation of the management target device from the acquired performance and operation information of the management target device Operating status analysis means for analyzing the situation, and the operating status analysis means determines the operating status relative to the performance of the management target device based on the operating rate of the management target device or the number of jobs to be processed by the management target device. Classify according to the conditions, and use the result of the classification as the evaluation result of the operation status of the management target device. To obtain the evaluation results for a plurality of management target device, in accordance with the combination of evaluation results of a plurality of management target device generates and information prompting the additional installation destination change or new management target device manage the target device output It is characterized by doing.

A second technical means is the image processing apparatus according to the first technical means, wherein a device on the network processes image data, and the management device stores the image data of the image processing device as performance information of the management target device. The processing capability information is acquired, and information on the image processing amount requested of the image processing apparatus is acquired as the operation information of the management target device.

According to a third technical means, in a management program for managing a management target device installed on a network, device information acquisition for acquiring performance information of the management target device from a management target device installed on the network in a computer Management program for realizing the operation status analysis function that analyzes the operation status of the management target device from the function, the operation information acquisition function that acquires the operation information of the management target device , and the performance and operation information of the acquired management target device Therefore , the operating status analysis function classifies the operating status relative to the performance of the managed target device according to a predetermined condition based on the operating rate of the managed target device or the number of jobs to be processed by the managed target device. Result management result Evaluation result of target device operation status Then, obtain evaluation results for multiple managed target devices, and generate information that prompts you to change the installation location of the managed target devices or add new managed target devices according to the combination of evaluation results for multiple managed target devices. It is a feature that is output function.

According to a fourth technical means, in the third technical means, the management target device on the network processes the image data, and the management program stores the image of the image processing device as performance information of the management target device. The present invention is characterized in that a function of acquiring data processing capability information and acquiring information related to the image processing amount requested of the image processing apparatus as operation information of the management target device is realized.

  According to the present invention, based on the performance of a device connected to the network and its operating status, it is analyzed whether the performance of the device is fully demonstrated, and the unreasonableness that does not match the performance of the device By extracting the presence of a device in a proper operating status and outputting information that prompts the user to replace the device or add a new device, the network device can be used efficiently.

  FIG. 1 is a diagram showing a system configuration example to which a printer control system according to the present invention can be applied. A plurality of printing apparatuses (printers) A, B, and C, a plurality of host apparatuses, and a print server are connected to the network. The printers A, B, and C may be, for example, a multifunction machine having a print function, a FAX function, a copy function, and the like, and perform print output according to a print job requested from the print server. The print request from the network device is managed by the print server, and the print server selects a printing apparatus that requests printing.

  In this case, any of the host devices can be applied to the network device management device according to the present invention. That is, one of the host devices holds a network device management program according to the present invention, and functions as a network device management device according to the present invention. The management device manages the operating status of the target device for operating status management. In this case, it is assumed that printing apparatuses A, B, and C are applied as target devices of the management apparatus. The printing apparatus corresponds to the image processing apparatus of the present invention.

In this case, the management apparatus acquires performance information from each printing apparatus connected to the network. The performance information is information related to the image processing capability of the printing apparatus, for example, information such as performance such as printing speed and the presence or absence of various functions. Specific examples of performance information will be described later.
Further, the management apparatus acquires operation information of each networked printing apparatus. The operation information can be known from, for example, the status of print output required for the printing apparatus. For example, the print server manages print request information (print job log information) for each printer. The print job log information includes information related to the print processing amount requested of the printing apparatus. In this case, the information related to the print processing amount may be information on the number of sheets to be printed out or the number of jobs. The management apparatus acquires the print request information from the print server, uses this information as printer operating information, and analyzes the operating status of the printer.

  A configuration in which each network device sends a print job to an arbitrary printer without having a print server is also common. In this case, the management device acquires the print request information managed by each host device and the performance information of each printing device, and analyzes the operating status of the printing device.

FIG. 2 is a diagram for explaining an example of job management in the print server.
The print server manages the print processing status according to a print job transmitted to a printer connected to the network. These pieces of information correspond to device operation information. As management items in this example, for each print job, for example, print date and time, user information (IP address of the user's device), print size, number of prints, number of copies, and printing apparatus (information that can specify the printing apparatus) Is set.

FIG. 3 is a diagram for explaining an example of job management in each network device. FIG. 3A shows management information by the machine A, and FIG. 3B shows management information by the machine B.
In a configuration in which the print server as shown in FIG. 1 is not used on the network and each network device transfers a print job to the printing apparatus, the management apparatus such as the print server collectively performs the print job as shown in FIG. Job management cannot be performed. Accordingly, in this case, the print job is managed by each device (machine). As in the example of FIG. 2, the management items include print date and time, user information (IP address of the user's device), print size, number of prints, number of copies, and printing device (information that can identify the printing device). is there.

FIG. 4 is a flowchart for explaining an example of information processing by the management system of the present invention. The network device management device first acquires performance information of a target device (for example, a printing device) connected to the network (step S1). As for the performance information of the printing apparatus, the management apparatus acquires the performance information held in the printing apparatus via the network.
Further, the management apparatus acquires operation information of the printing apparatus (step S2). The operation information is managed by the print server and each network device as log information of the print job as described above, and the management apparatus acquires the log information of the print job via the network.

  Next, the management apparatus sets a specific period (step S3). The specific period is a target period for analyzing the operation status of the device, and the analysis target period can be set in the management apparatus. This period can be set, for example, as a past period that goes back one month from the current time, or a specific date and time can be set and the specific date and time to the present can be set. Further, a period from a specific date and time to a date and time when a specific period has elapsed may be set. Alternatively, the period may be set directly such as one month in July of this year, three months in May to July, and so on.

Here, for example, when a new device is introduced into the network, or when a device connected to the network is updated, by setting an analysis target period of a predetermined period (such as one month), the device It is possible to analyze the usage situation within a certain period after it is newly used.
The setting of the specific period in step S3 may be performed before acquiring the performance information and operation information of the target network device. In this case, the operation information is set within the set period. Only the operation information may be acquired.

  Then, the management device analyzes the operation status for a specific period (step S4). Here, based on the acquired performance information and operation information of the network device, information indicating whether the analyzed device is properly used is generated and output. Further, information for changing the installation destination of the device or information for prompting the addition of a new device on the network is output (step S5). An example of generating such analysis information will be described later. The information output destination is a display unit of the management apparatus or a predetermined external device via a network.

  FIG. 5 is a diagram for explaining a configuration example of the management apparatus and the target network device. It is assumed that a management device 10 for managing the operation status of network devices and two network devices serving as management targets by the management device 10, that is, a printing device A and a printing device C, are connected to the network. The management apparatus 10 includes a LAN I / F 16 and can be connected to a LAN. Thereby, connection with the apparatus via a network is implement | achieved.

  In addition, the management apparatus 10 stores an operation unit 13 including a touch panel and hard key groups for inputting user operations, a display unit 11 for displaying various information such as an input menu screen, and various data files and program files. HDD 12 to be used. The display unit 11 can display an analysis result of the operation status of the device by the management program.

The above management program is held in the memory 14, and the CPU 17 uses this management program to acquire device performance information and operation information, and analyze the operation status of the device in the analysis target period. Acquisition of performance information and operation information is executed by the information acquisition unit 15. The information acquisition unit 15 acquires performance information of the device and operation information of the device from a predetermined device connected via the LAN I / F 16. As a network protocol for acquiring information, for example, SNMP (simple network protocol) as described in detail below can be used.
Information on the operating status of the device analyzed by the CPU 17 is displayed and output on the display unit 11 and is also output to a predetermined external device via the network. Both the display output and the output to the external device may be executed, or one of them may be executed.

The printing apparatus A and the printing apparatus C, which are network devices, are devices having different performance. For example, a peripheral device 40 such as a finisher of a copying apparatus is attached to the printing apparatus C, and has a higher function than the printing apparatus A.
In the printing apparatus A, the document input unit 21 includes an image reading device (scanner) that reads an image of a document by a CCD or the like and outputs an image signal. The image processing unit 22 performs image processing on the image signal output from the document input unit 21 or the image signal transmitted from the outside, and generates print execution data to be printed by the printer unit 24. The printer unit 24 prints the print execution data subjected to image processing.

The printing apparatus A includes a LAN I / F 25 and can be connected to the LAN. Network communication via the LAN is controlled by the network controller 26.
The CPU 28 of the printing apparatus A controls each part of the apparatus. The HDD 23 stores various data files and program files.

  Further, the printing apparatus A is provided with an MIB (Management Information Base) for holding the performance information of the printing apparatus A so that it can be acquired by the management apparatus. MIB refers to a database of information that is disclosed by a network device managed by SNMP (Simple Network Management Protocol) in order to inform the outside of its state.

  As a method for managing devices on a network constituting a large-scale network system, the International Organization for Standardization (ISO) provided a general-purpose reference framework called an open system interconnection (OSI) model. The OSI model of the network management protocol is called a common management information protocol (CMIP). CMIP is a European common network management protocol, and SNMP is a variant protocol related to CMIP.

  The management apparatus 10 can obtain data on the network and change data by communicating with the agent software of the management target printing apparatus using the management program. An agent is software that runs as a background process for a printing apparatus that is a target device. When a user requests management data from a device on the network, the management program puts object identification information in a management packet or frame and sends it to the target agent.

  The agent interprets the object identification information, retrieves data corresponding to the object identification information, puts the data in a packet, and sends it back to the user. Sometimes the corresponding process is invoked to retrieve the data. The MIB is a database for the agent to hold data relating to his / her state in the form of a database.

In this way, with the MIB 27 provided in the printing apparatus A, the management program of the management apparatus 10 can appropriately acquire the management information managed and held in the MIB 27.
It is obvious that the system in which the management apparatus 10 acquires performance information and the like from the target network device is not limited to the configuration using the MIB as in this example, and manages the performance information prepared in advance by the network device. Any system can be applied as long as it can be loaded into the apparatus.

  The printing apparatus C has the same functions as the printing apparatus A, and further includes a peripheral device 40. That is, the printing apparatus C includes a document input unit 31, an image processing unit 32, an HDD 33, a printer unit 34, a LAN I / F 35, a network controller 36, an MIB 37, and a CPU 38 having the same functions as the printing apparatus A. The peripheral device 40 is a device such as a finisher added to the printing apparatus, for example, and a predetermined additional function is given by the peripheral device 40. Peripheral devices are controlled by the controller 41 based on instructions from the CPU 38. The MIB 37 holds performance information of the printing apparatus C including the performance of the peripheral device 40, and the performance information can be acquired from the management apparatus 10.

  FIG. 6 is a diagram illustrating an example of device performance information. The network device that is the target of the management apparatus holds information corresponding to the items shown in FIG. 6 as its own performance information. These pieces of performance information are stored in an MIB as shown in FIG. 5, for example, and can be acquired from the management apparatus.

  In the example of FIG. 6, it is assumed that there are printing apparatuses A, B, and C as network devices that are targets of the management apparatus. The performance information of each device includes the following items: printing speed (sheets / minute), copy, printer, FAX, duplex (double-sided printing), trays 1 to 4, staples, paper folding, punch, color, large capacity tray , Etc. are set. In this case, the specific specifications for the printing speed are stored, and for the other items, the presence / absence of a function corresponding to each item is stored.

  For example, the printing apparatus C has a printing speed of 60 sheets / min and the fastest printing speed of the three printing apparatuses, and includes a staple, paper folding and punching function, and a large capacity tray. Also, trays 1 to 4 are provided, and four types of paper can be fed. On the other hand, the printing apparatus A has a medium processing speed among the three printing apparatuses and can only perform color printing. The printing apparatus B is a low-end model having the slowest processing speed and only having basic functions. As described above, devices having different processing speeds and functions are generally connected to the network.

  FIG. 7 is a diagram for explaining an example (analysis example a) of an operation state analysis process in the management apparatus. As described above, the management apparatus 10 acquires device performance information from the target network device using the management program. Further, the operation information of the target network device is acquired from the above-described print server and each network device. Then, from the performance information and operation information of these devices, it is possible to analyze the operation status of the device and output the analysis result using a predetermined output means.

FIG. 7 shows an analysis example of the operating status of the printing apparatuses A and C. First, the printing apparatus A has a performance of 40 sheets / minute as a speed (printing speed). The analysis target period is set to one month. Here, based on the operation information of the printing apparatus A during the analysis target period, it is assumed that the total number of prints is 20840.
When the operation status of the above-described device is analyzed by the operation status analysis function by the management program of the management device, the evaluation of the printing device A is, for example, “4” in the evaluation (step 5). The five-stage evaluation can be evaluated by the operation rate with respect to the capability of the device. The evaluation “4” is, for example, an evaluation “I am doing my best”.

On the other hand, the printing apparatus C has a performance of 60 sheets / minute as a speed (printing speed). Then, it is assumed that the analysis target period is set to one month, and the total number of printed sheets is 15260 from the operation information of the printing apparatus C in the analysis target period.
When the operation status of the above-described device is analyzed by the operation status analysis function by the management program of the management device, the evaluation of the printing device C is, for example, “2” in the evaluation (step 5). The evaluation “2” is, for example, an evaluation “not used well”.

Then, the management program of the management apparatus performs display and data output for prompting the switching of the printing apparatus A and the printing apparatus C on the network from the analysis result of the above-described device. Alternatively, a display or data output for appealing to use the marking device C more is performed.
That is, the operation status analysis function of the management program can output information indicating whether or not the analyzed target device is properly used, and can output information that prompts a change in the installation destination of the device.

  The evaluation of the operation status of the target device based on the performance information and the operation information and the analysis based on the evaluation result are executed by a predetermined algorithm that the management program has in advance. For example, the actual operation status for the performance of the target device is classified according to predetermined conditions such as the operation rate and the number of jobs as the evaluation result. An analysis result such as addition can be generated.

FIG. 8 is a diagram for explaining another example (analysis example b) of the operation status analysis process in the management apparatus. Also in the example of FIG. 8, an analysis example of the operating status of the printing apparatuses A and C is shown. The printing apparatus A has a performance of 40 sheets / minute as a speed (printing speed). The analysis target period is set to one month. Here, based on the operation information of the printing apparatus A in the analysis target period, for example, it is assumed that the number of jobs (jobs) for performing print processing of 40 sheets or more is 130 times.
When the operation status of the above-described device is analyzed by the operation status analysis function by the management program of the management device, the evaluation of the printing device A is, for example, “4” in the evaluation (step 5). The five-stage evaluation can be evaluated by the operation rate with respect to the capability of the device. The evaluation “4” is, for example, an evaluation “I am doing my best”.

On the other hand, the printing apparatus C has a performance of 60 sheets / minute as a speed (printing speed). Assume that the analysis target period is set to one month, and the number of jobs (jobs) for performing print processing of 40 sheets or more is 45 from the operation information of the printing apparatus C in the analysis target period.
When the operation status of the above-described device is analyzed by the operation status analysis function by the management program of the management device, the evaluation of the printing device C is, for example, “2” in the evaluation (step 5). The evaluation “2” is, for example, an evaluation “not used well”.

  Then, the management program of the management apparatus performs display and data output for prompting the switching of the printing apparatus A and the printing apparatus C on the network from the analysis result of the above-described device. Alternatively, a display or data output for appealing to use the marking device C more is performed.

  FIG. 9 is a diagram for explaining still another example (analysis example c) of the operation status analysis process in the management apparatus. The example of FIG. 9 shows an analysis example of the operating status of the printing apparatus B. The printing apparatus B has a performance of 25 sheets / minute as a speed (printing speed). The analysis target period is set to one month. Here, based on the operation information of the printing apparatus B during the analysis target period, it is assumed that the total number of prints is 18640.

  When the operation status of the above-described device is analyzed by the operation status analysis function by the management program of the management device, the evaluation of the printing device A is, for example, “5” in the evaluation (step 5). The five-stage evaluation can be evaluated by the operation rate with respect to the capability of the device. Evaluation “5” is an evaluation that “the operation status exceeds the limit of the performance of the device”.

  The management program of the management apparatus performs display and data output for prompting the user to replace the printing apparatus B with a higher-speed machine (high-speed machine) on the network based on the analysis result of the device. At this time, display or data output for prompting to add a new printing apparatus to the position of the printing apparatus B may be performed.

  That is, the operation status analysis function of the management program can output information indicating whether or not the analyzed target device is properly used, and can output information that prompts the addition of a new device.

  As described above, the operation status analysis unit according to the embodiment of the present invention analyzes whether or not the network device that is the target of management sufficiently exhibits its performance, and does not match the performance of the device. It is possible to extract the presence of a device in a reasonable operating condition. For such a device, information for changing the installation location of the device or information for prompting the addition of the device can be generated and output from a predetermined output means.
