[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an image processing system, and is transmitted as a job from a host computer connected via a network as a vector image in a page description language (PDL) format, a document in a PDL format, or a raster image. The present invention relates to an image processing system that develops a job targeted for image output, performs image processing on the job, sends the image to an image output device, and outputs the image.

Description of the Related Art Conventionally, in an image processing system in which a plurality of image processing apparatuses are connected on a network and an output apparatus is connected to each of the image processing apparatuses, a host computer connected via the network outputs each image. The device is recognized as an independent device.

In the case of this processing system, there is one rasterizer, and bitmapping of an actual image sent to each output device by this rasterizer is performed serially.

However, once a job is entered from the host computer into the queue of the image processing apparatus, the printing is completed by the number of jobs in the queue before the job is subjected to bitmap expansion processing. Time is decided. Further, there is a case where the output device has a failure in the previous job and the actual printing operation is not performed, and the subsequent job is kept waiting.

After creating a database of accessories attached to the copying machine 100n,
It is assumed that the image processing apparatus 101n is periodically polled to dynamically monitor the connection status of accessories attached to the copying machine 100n.

In this state, the host computer 1
02 and the monitor server 103, the transfer source,
A process of specifying a transfer destination image processing system and setting transfer conditions will be described.

FIG. 3 is a flowchart showing processing for setting transfer from the image processing system A to another image processing system. First, the host computer 102 transmits a user password to the monitor server 103 (step S301), and the monitor server 103 checks the password and determines whether to permit the setting (step S301).
302). Here, if the password is not correct, the transfer destination and setting are not possible (step S303), and the process ends.
If it is correct, the list of the transfer source image processing systems (in this example, the image processing system A is selected as the transfer source) is stored in the host computer 102 as the network client.
Is notified (step S304).

When the setting is permitted from the monitor server 103, the host computer 102 proceeds to the following setting operation. Note that the setting items here are notified to the host computer 102 via the network as menus.

Display of list of image processing systems of transfer source and transfer destination: Monitor server 103 => host computer 102 Transfer source list, transfer destination list Note that the image processing systems targeted for the transfer source and transfer destination list are as follows.
It is limited to image processing devices existing in the same network. At this time, the transfer condition is that the monitor server 103 also exists in the same network. In addition, job transfer across different networks via a gateway is not performed. Therefore, when configuring the load-distributed image processing system, the image processing apparatus 101
n, monitor server 103, host computer 102
It is assumed that the IP address setting and the subnet mask are set to appropriate numerical values in advance.

The specific same network referred to here is the same network in which each network node constituting the load balancing type image processing system is determined from an IP address and a subnet mask.

The transfer destination is 2 for one transfer source.
Up to one can be set (step S305).

Display of list of transfer conditions: monitor server 103 => host computer 102 Next, conditions for performing job transfer from the image processing apparatus systems A to B and C are set (step S306). here,
It is assumed that the monitor server 103 has notified the host computer 102 of accessory mounting information of the copying machine 100A of the image processing system A together with other transfer condition setting information in advance.

FIG. 4 is a diagram showing a configuration of a job management table of each image processing system to the monitor server.

The setting information menu displayed on the host computer 102 by the monitor server 103 includes the setting of the maximum value per day, week, or month of the copy volume of the copying machine 100A of the image processing apparatus system A. Whether there is a transfer when an operator error has occurred, whether or not there is a transfer when a serviceman error has occurred, and permission to use accessories for executing a job.

For this copy volume, a specific numerical value of the volume is set, and whether or not transfer is permitted when the numerical value is exceeded is set. For an operator error, a code of an error to be detected is input, and whether or not transfer is permitted when the error is detected is set. If the specific error code to be detected is not input, that is, if the code is 0, all operator errors are to be detected and whether or not transfer is permitted when any operator error occurs is set. Becomes Regarding the serviceman error, it is the same as the case of setting the operator error. The use permission of the accessory is subject to the setting conditions, but the monitor server 103 does not notify the host computer 102 of the accessory that is not attached to the target copier 100A. Accordingly, permission to use an accessory that is not mounted on the copying machine 100A does not appear on the setting menu of the host computer 102.

Next, as a setting information menu displayed on the host computer 102 by the monitor server 103,
There are transfer conditions depending on the image processing apparatus 101A. These include the case where an arbitrary job enters an arbitrary queue of the image processing apparatus 101A, the number of pages and the number of copies of the job immediately before the queue, the presence or absence of transfer when the processing time satisfies certain conditions, the presence of an arbitrary job Is in the queue of the image processing apparatus 101A, there is the presence or absence of transfer when a certain number of jobs have been spooled earlier than that.

With respect to the number of pages, the number of copies, and the processing time of the job in this queue, the setting of each maximum value and the case where each actual measurement value notified to the monitor server 103 by the image processing apparatus 101A exceeds the maximum value. Configure settings to enhance transfer. The number of pages and the number of copies of an arbitrary job is detected by a preprocessor in the image processing system A.

Any one of the elements constituting the transfer condition

3 can be set to enter the transfer operation.

Then, the image processing system B is specified as the first transfer destination (step S307), and the image processing system C is specified as the second transfer destination (step S308).

As described above, a series of transfer condition setting processing is performed between the host computer 102 and the monitor server 103.

Next, the operation of actually transferring a job will be described.

FIG. 5 is a flowchart showing job transfer conditions in this embodiment. First, step S50
In step 1, it is determined whether the transfer condition depends on the copying machine or the job processing load of the image processing apparatus. Here, if it depends on the load of the image processing apparatus, step S
Proceeding to 502, the image processing system A notifies the monitor server 103 of the load on the image processing apparatus. Then, in step S503, processing depending on the load of the transfer source image processing apparatus is performed.

On the other hand, if it depends on the state of the copying machine in step S501, the flow advances to step S504, and the image processing system A notifies the monitor server 103 of the state of the copying machine. Then, in step S505, a process depending on the copying machine to be printed is performed, and this process ends.

<Process Dependent on Load of Image Processing Apparatus> Here, processing in which the above-described transfer condition depends on the load of the image processing apparatus will be described with reference to FIG.

First, a determination is made depending on the load of the image processing apparatus (step S601). Image processing device 101A
Saves the received job in the spooler 206, detects the number of pages and the number of copies of the job with the preprocessor,
First, it is determined whether the job is spooled in the queue. If no job has been spooled first, the transfer condition depending on the state of the copying machine 100A is satisfied, and normal processing is performed until the monitor server 103 permits the transfer of the job.

On the other hand, when one or more jobs exist in the queue, the total number of existing jobs is counted by the monitor server 10.
When the polling response is received from the third server, the monitor server 103 is notified. As a result, the monitor server 103
As shown in (1), a new management table for this job is created internally, and the total number of jobs is registered in the total job field of the queue. The number of pages and the number of copies of the job immediately before the queued job are detected in advance by the preprocessor, and are simultaneously registered in the fields of the number of pages and the number of copies of the immediately preceding job in the job management table inside the monitor server 103. You.

The processing time field of the immediately preceding job in the job management table inside the monitor server 103 is as follows:
The image processing apparatus 1 of the job immediately before the job to be managed
01A, the elapsed time from the start of the processing of the immediately preceding job is sent from the monitor server 103 to the image processing apparatus 10.
Each time polling of 1A is performed, the image processing apparatus 101A notifies the monitor server 103 and registers the notification.

The monitor server 103 includes the image processing device 1
The job management table is updated with information depending on the image processing apparatus every time polling is performed on 01A, and when the transfer condition set in the transfer condition setting is satisfied, the fact is notified to the host computer 102 (step S60
2).

When the transfer permission is determined by the host computer 102 (Yes in step S603), the job is transferred from the image processing system A to the image processing system B, and the image processing system A notifies the internal job log 2
11 (step S604).

On the other hand, when the host computer 102 permits the transfer of the job, the monitor server 103 sets the ID of the image processing apparatus B to which the job has been transferred to the ID field of the image processing apparatus in the internal job management table. It is registered (step S605).

<Process Depending on Copying Machine Status> Next, the process in which the above-described transfer conditions depend on the printing machine status to be printed will be described with reference to FIG.

First, when the order of expansion processing of an arbitrary job stored in the queue comes, the image processing unit 204 of the image processing apparatus 101A communicates with the copying machine 100A and performs predetermined determination processing on the expanded job. (Step S701). Also, for a development job for which processing is disabled by the image processing unit 204, the fact is notified to the monitor server 103.

Here, it is assumed that the processing cannot be performed in the following cases. -When the number of prints per unit time in the copier 100A exceeds a preset number of prints-When a specified or unspecified operator error occurs in the copier 100A-When specified in the copier 100A Or when an unspecified serviceman error occurs.-When the management key is not turned on in the copier 100A.-When a management card is not inserted in the copier 100A.-When an ID code is input in the copier 100A. When the above-mentioned processing impossible state occurs in the copying machine 100A, the image processing apparatus 101A
At the time of polling from the server, the fact is notified to the monitor server 103.

The monitor server 103 includes the image processing device 1
The job management table is updated with information depending on the image processing apparatus every time polling is performed on 01A, and when the transfer condition set in the transfer condition setting is satisfied, the fact is notified to the host computer 102 (step S70
2).

When the transfer permission is determined by the host computer 102 (Yes in step S 703), the job is transferred from the image processing system A to the image processing system B, and the image processing system A notifies the internal job log 2.
11 (step S704).

On the other hand, when the host computer 102 permits the transfer of the job, the monitor server 103 sets the ID of the image processing apparatus B to which the job was transferred to the ID field of the image processing apparatus in the internal job management table. It is registered (step S705).

In any of the above cases, if the transfer condition is not satisfied, a match between the job and the image processing system that executes the job is determined. Here, the matching determination between the job and the image processing system that executes the job refers to checking the following inconsistency by checking the job characteristics of the spooled job by the preprocessor inside the image processing apparatus 101A. is there. When double-sided printing is specified, but the copier 100A of the image processing system A does not have the function.- When staple is specified, but the copier 100A of the image processing system A does not have the function. When sorting is specified but the copier 100A of the image processing system A does not have the function.-When paper deck feeding is specified but the copier 100A of the image processing system A does not have the function. -Although the color output is specified, the image processing system A
When the above-described inconsistency state occurs in the image processing system A, the image processing apparatus 101A
At the time of polling from the server, the fact is notified to the monitor server 103.

The monitor server 103 includes the image processing device 1
The job management table is updated with information depending on the image processing apparatus every time polling is performed on 01A, and when the transfer condition set in the transfer condition setting is satisfied, the fact is notified to the host computer 102.

When the transfer permission is determined by the host computer 102, the job is transferred from the image processing system A to the image processing system B, and the image processing system A records the fact in an internal job log 211.

On the other hand, when the host computer 102 permits the transfer of the job, the monitor server 103 sets the ID of the image processing system B to which the job was transferred to the ID field of the image processing apparatus in the internal job management table.
Register

The above-described determination and transfer processing are repeated, and the job is transferred from the image processing system A to the image processing systems B and C. Here, in the case of a job for which transfer is also determined in the image processing system C, the job is returned to the image processing system A to which the job was sent first.

FIG. 8 is a flowchart showing a process in which the transfer condition depends on the load of the image processing apparatus in the image processing system C. FIG. 9 shows a process in which the transfer condition depends on the state of the copying machine to be printed in the image processing system C. It is a flowchart which shows.

When a job is returned from the final transfer destination to the image processing system A to which the job was first transferred,
The monitor server 103 does not request the host computer 102 to determine whether the transfer is permitted.
Automatic transfer is performed according to the judgment of 03.

The job returned to the image processing system A in this manner is moved to a specific queue in the image processing system A, or sent to an arbitrary output device and forcibly copied / printed. Alternatively, the setting of whether or not the image data is transferred to another image processing system may be based on the setting of the load distribution type image processing system administrator.

Further, the processing of a job or an arbitrary transfer destination of a job which has not been a target of the job transfer is sent from the host computer 102 to the inside of the image processing apparatus.
When the processing order comes from the processing waiting state by the spooler 206 of 1A, the image processing apparatus 101A converts the job into bitmap data by the rasterizer / PDL processing unit 203, and the frame buffer 20 in the image processing apparatus 101A.
9 to store the bitmap data. Thereafter, printing is performed from the digital copying machine 100A according to the print parameter information included in the previous job.

Here, the image processing apparatus 101A issues a print request to the digital copying machine 100A. At this time, if the file developed by the image processing apparatus 101A spans a plurality of pages, the image processing apparatus 101 writes the image data for each page in the image storage area of the digital copying machine 100A. When the image data is written in the image storage area, the digital copying machine 100A starts printing. When the printing of the required number of images per page is completed, the digital copying machine 100A notifies the image processing apparatus 101A of the completion. If a paper jam or the like occurs during printing one page, the host computer 102 is notified of the occurrence. continue,
The image processing apparatus 101A sends the next page of image data to the digital copying machine 100A. After that, the above operation is repeated until the last page where the job is developed.

At the same time, the image processing apparatus 101A instructs the start of printing to start measuring the copy / print processing time by the timer 205. Digital copier 1
00A indicates execution of a job, that is, copy / copy in a predetermined mode.
The function instructed to print is executed, and the image processing apparatus 101A is notified of a report indicating completion and a normal end. Upon receiving this notification, the image processing apparatus 101A stops counting the copy / print processing time, confirms that a normal operation has been performed, and records the log in the job log 211. As a log condition, a log is recorded even when a normal operation is not performed.

A series of processing steps for a job for which transfer has not been performed is the same in the image processing systems B and C.

The job management table shown in FIG. 4 created in the monitor server 103 is stored in the monitor server 103 for a certain period after the job is completed. Whether the job is to be left for a certain period of time after the end, to keep a certain number of jobs retroactively from the latest job, or to be deleted immediately upon completion of the job is determined by the load balancing type image processing system administrator to the monitor server 103. Depends on setting conditions.

According to this embodiment, the system is networked, and the client-server system or the Web (Web)
Load distribution can be performed between systems in which distributed processing as in b) is mutually connected.

Further, it is possible to prevent the load on a specific image processing apparatus from increasing or decreasing, and to distribute the load of each image processing system connected to a network and managed by a monitor server comprehensively. .

Therefore, the load amount between the image processing apparatuses is measured mainly by the monitor server, the data is accumulated, the transfer of the job is determined, and the load distribution with the improved system driving ratio is performed. Becomes possible.

Even if the present invention is applied to a system including a plurality of devices (for example, a host computer, an interface device, a reader, a printer, etc.), an apparatus (for example, a copier, a facsimile) comprising one device Device).

Further, an object of the present invention is to supply a storage medium storing a program code of software for realizing the functions of the above-described embodiment to a system or an apparatus, and to provide a computer (CPU or MP) of the system or apparatus.
