Abstract

PURPOSE:To improve the performance of interpreter processing by reducing the syntax analysis processing occupying a large proportion of the processing time as much as possible. CONSTITUTION:With respect to an instruction statement executed once, a list of vocabulary generated by a vocabulary analysis means 11 is stored in a vocabulary list storage area 141, and parameters generated by a syntax analysis means 12 are stored in a parameter storage area 142. When a list of vocabulary has the sane value as the list of vocabulary stored in the vocabulary list storage area 141, an instruction management means 15 makes an instruction execution means 13 execute the instruction statement without passing the syntax analysis means 12 by parameters stored in the corresponding parameter storage area 142.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substitute output control system, and particularly when outputting image data, if the output device fails and cannot output, the output destination is changed according to a preset table and output is performed. This is a substitute output control method.

[0002]

2. Description of the Related Art In the conventional proxy output control method, when the output destination is a failure as a result of output, the substitute output destination is obtained from a preset table, and is output as the output destination. .

A newspaper company that transmits photographs as image data will be described below by taking photograph data output control as an example.

First, an image number (for example, M0102) desired to be output and an output destination (for example, printer 1) are input from a keyboard and stored in a data storage unit.

Next, a photographic image is read from the image data file based on the image number stored in the data storage unit, transmitted to the output destination stored in the data storage unit, and printed.

The control of the output process will be described below.

First, the photograph data read from the image data file is output to the output destination held in the data storage unit. The output result is judged, and if it is completed normally, the output process is ended. If it is abnormal, the process moves to the next operation, and it is determined whether or not to perform proxy output.

Next, the destination data section is checked to see if a substitute output destination is set for the output destination held in the data storage section. If a substitute output destination is set, this is stored as an output destination in the data storage unit and output. If not set, output processing ends as an error.

Next, output is performed to the output destination (alternative output destination) currently held in the data storage unit, the result is judged, whether or not to substitute is determined, and the output destination is changed to the data storage unit. Hold and output again. This process is repeated.

[0010]

The above-described conventional proxy output control system has the following drawbacks. 1. When the output destination device is faulty, the proxy output is performed. However, from the output, it cannot be determined whether the output is the proxy output or the address is originally addressed to itself. For this reason, it takes time and effort to look at the image data, estimate the destination, and confirm each one by telephone or the like. 2. If the output concentrates on one output destination, it takes a long time to output even if the surrounding devices are idle.

[0011]

According to the proxy output control method of the present invention, output information data including a destination name and an image number is input, image data corresponding to an image data file and an image number is read, and a list of output destinations is displayed. In the image data transmission system that obtains the output destination and the alternate output destination corresponding to the destination name from the table and outputs the image data, if the output destination device cannot output the image data due to a failure, hold it in the data storage unit. Get a substitute output destination,
The image data and the destination name to be originally output are printed together on the substitute output device.

The processor 3 performs various controls necessary for the proxy output control of the image data. First, the processor 3 receives and holds the destination name and the image number which are instructed to be input. Next, the image data corresponding to the image number is read from the image data file 2 and held. Next, the output destination and the substitute output destination corresponding to the destination name are obtained and held from the preset table. Next, the destination name is imaged and saved. Finally, the imaged destination name and the image data are printed together at the output destination. Such an operation is performed to control the flow of operations.

Therefore, the image data corresponding to the image number stored in the input reception processing unit 6 and the data storage unit 11 which receives the information input from the keyboard 1 and transmits the information to the data storage unit 11 of the main memory 4 and holds it. Is read from the image data file 2, and the image read processing unit 7 to be held in the data storage unit 11 and the output destination and the substitute output destination are determined from the destination name held in the data storage unit 11,
Output destination determination processing unit 9 stored in the data storage unit 11, image processing unit 10 that visualizes the destination name stored in the data storage unit 11, output destination determination and destination name imaging, and output destination device In the case of a failure, the output processing unit 8 that changes the output destination to the alternate output destination and outputs the image data, the data storage unit 11 that holds the information input from the keyboard 1, the information obtained from the destination data unit 12, and the keyboard 1
A destination data section 1 and the like for holding the settings of the output destination and the substitute output destination corresponding to the destination name input from

Next, the operation of the present invention will be described with reference to the flow chart of FIG. 2 by taking a newspaper company that transmits photographs as image data as an example and taking the output control of the photograph data as an example.

First, in operation step S1, a destination name (for example, M0102) desired to be output is input from the keyboard 1, and the input reception processing unit 6 receives it and informs the data storage unit 11 to hold it. Perform the operation. The data storage unit 11 holds the destination name and the image number with the configuration shown in FIG.

Next, in the operation step S2, the image reading processing unit 7 reads out the photographic data from the image data file 2 based on the image number held in the data storage unit 1.

Next, in the operation step S3, the output destination determination processing unit 9 outputs the output destination (for example, the printer 1) from the destination data unit 12 based on the destination name stored in the data storage unit 11. ) And a substitute output destination (for example, the printer 3) that substitutes the output when a failure occurs, and informs the data storage unit 11 to hold it. Perform such an operation. The destination data unit 12 holds the output destination / alternative output destination corresponding to the destination name with the configuration shown in FIG. Then, the imaging processing unit 10 visualizes the destination name held in the data storage unit 11 into an image, and the data storage unit 11
To be held together with the image data. Next, the operation step S is performed to the output destination stored in the data storage unit 11.
The photographic image read in 2 and the output control unit 8 are transmitted to the printing unit 5 and output.

Next, the control in the analysis / output processing of the operation step S3 will be described with reference to FIG.

First, in operation step S10, based on the destination name stored in the data storage unit 11, the output destination determination processing unit 9 determines whether or not there is a failure with the output destination from which the destination data unit 12 actually outputs. When an occurrence occurs, an alternate output destination for the alternate output is obtained, transmitted to the data storage unit 1, and held therein. At the output destination, the length of each output queue is compared and the shortest output destination is selected.

Next, in an operation step S11, the destination name held in the data storage unit 11 is set to the image processing unit 1
0 is converted into an image from a character code and held in the data holding unit 11 together with the photographic data.

Next, in operation step S12, the imaged destination name and photograph data held in operation step S11 are output together.

The output processing result is judged in the operation step S13, and if the output is normally completed, the output processing is ended. If it is abnormal, the process proceeds to the next operation step S14, and it is determined whether or not to perform the substitution.

Next, in operation step S14, the substitute output destination held in the data storage unit 11 is confirmed. If the substitute output destination is not cut off, the operation proceeds to operation step S17, and failure recovery is provided. If the substitute output destination is set, the operation proceeds to operation step S15 and the substitute output is performed.

Next, in the operation step S15, the output is changed to the substitute output destination held in the data storage unit 11, and the destination name and the photographic data which are to be output in the operation step S12 are output.

The output result is judged in the operation step S16, and if it is normally ended, the output process is ended. If the processing is abnormally terminated, the process proceeds to operation step S17 and waits for failure recovery at the original output destination.

Next, in operation step S17, the output is registered in the output queue and the output is waited until the failure is recovered.
At this time, the output destination stored in the data storage unit 11 is used.

Next, in operation step S18, it is confirmed whether or not the failure is recovered. If the recovery has not been completed, the process returns to operation step S18 to wait for the recovery of the failure. If it has been recovered, the operation proceeds to operation step S19, and the output is performed again.

Next, in the operation step S19, in order to perform the output again, it is once deleted from the output queue, and the process returns to the operation step S12 to perform the operation from the output.

[0033]

As described above, the proxy output control system of the present invention has the following effects. 1. Even when the output destination device outputs a substitute for a failure, the original destination name is retained and the destination name and source are printed together with the image data. For this reason, it is possible to determine at a glance whether the output is a substitute output or it is originally addressed to itself, and it is not necessary to guess and judge the image data and check each one. 2. A plurality of output destinations are treated as one logical destination name. Therefore, the output can be distributed to a plurality of output destinations, and the time required for the output can be significantly reduced even when the output is concentrated on one destination.
