Abstract

PURPOSE:To easily and speedily analyze the malfunction of a host system or the errorneous design of the host system by outputting statistical information of incorrect data. CONSTITUTION:An incorrect data identification part 1 identifies whether data 11 received from the host system is incorrect data 12 or not, and a differentiation part 2 differentiates incorrect data 12 into previously decided classification. A counter control part 31 counts the number of reception times for incorrect data 12 for respective differentiated classification. An editing printing part 4 edits and prints the content of a counter group 32 by an instruction from the host system. Since statistical information of incorrect data 12 in reception data 11 from the host system can be obtained at a necessary time, it is easily analyzed the malfunction of the host system or the errorneous design of the host system.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for reporting received data errors in a receive-only printing device.

[Conventional technology]

Conventionally, this type of printing device has only a data receiving means and does not have a means to report the internal state of the device to a higher-level system, and if it receives invalid data, it ignores the data. Otherwise, the printing operation was stopped and a simple failure status display was displayed on the operation panel, etc.

[Problem to be solved by the invention]

Therefore, even if incorrect data is sent due to malfunction of the upper system or incorrect design of the control program, if the incorrect data is ignored, the abnormality may not appear in the print result. System malfunctions or misdesigns may go undetected and ignored, the functionality of the printing device may change, and data that was previously undefined and ignored as invalid data becomes valid. If this happens, the printing results may be adversely affected, and a great deal of effort may be required to correct it.

In addition, even if a simple internal state could be displayed, it took a long time to analyze the cause.

[Means to solve the problem]

In the present invention, the number of receptions of the received data is set to 1 for each classification, and the result can be printed. Depending on the number of times, the incorrect data is an intermittent failure or a fixed failure. Or, it can be determined whether it is a faulty design, and if it is a fixed failure or a faulty design, the part can be repaired immediately.

The present invention includes a fraudulent data identification unit that identifies whether data received from a host system is fraudulent data, a classification unit that separates fraudulent data into predetermined categories, and a system that receives fraudulent data for each classified classification. It consists of a counter that counts the number of times, and a printing section that edits and prints the contents of the counter section according to an operator's operation or a command from a host system.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

In FIG. 1 showing an embodiment of the present invention, a printing device according to an embodiment of the present invention includes a fraudulent data identification unit 1 that identifies whether or not received data 1 received from a binary system is fraudulent data. , a sorting section 2 that sorts the fraudulent data 12 identified by the fraudulent data identification section 1 into predetermined categories;
A counter control unit 31 that controls the counter to display an overflow indication and stop subsequent counting operations when the counter overflows by adding up the contents of the corresponding counter from 2 to 2, and a count value output command 41. If there is, the editing/printing section 4 edits the contents of the counter group 32 and outputs print data 42.

Next, the operation will be explained with reference to this drawing.

Data 1 received from the host system is first input to the fraudulent data identification unit 1 to identify whether it is defined data or not. If the data is defined data, it is treated as normal data and is led to a normal printing section, where normal printing operations are performed.

If the data is fraudulent, it is inputted to the next sorting section 2 as fraudulent data 12. The sorting unit 2 determines which of the pre-classified fraudulent conditions the input fraudulent data corresponds to, and the determined classification result is input to the counter control unit 31.

The counter control section 31 is the sorting section 2 of the counter group 32.
The content of the counter corresponding to the classification result is read out, and if it is in an overflow state, that state is held; if it is not in an overflow state, the value obtained by adding 1 to the content is stored in the counter.

While the above operations are being repeated, a count value output command 41 is outputted by an operation by an operator or by a command from a host system.

When the count value output command 41 is input, the editing printing section 4 reads the contents of each counter in the counter group 32, and
By editing the content according to a certain printing format and outputting the editing result to the printing unit as print data 42, statistical information of the fraudulent data is printed.

By operating as explained above, it is possible to obtain statistical information on invalid data among the received data from the upper system at the necessary time. The output status of the data can be easily analyzed, and the negative effects of fraudulent data that would not normally be apparent can be quickly eliminated.

〔Effect of the invention〕

By adopting the configuration described above, the present invention can output statistical information on fraudulent data, and can easily and quickly analyze malfunctions in the -4 Ni-1 system or incorrect design in the upper system. There is an effect that it can be done.

Claims (1)

[Scope of Claims] An unauthorized data identification unit that identifies whether data received from a host system is data that is not specified for the operation of the device; a sorting section that sorts the data into different categories; a counter section that counts the number of times fraudulent data is received for each category sorted by the sorting section; 1.
