Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a part program automatic diagnosing device which checks a command format of block data of a part program of a numerical control device and diagnoses whether or not there is an error in the block data.

[0002]

2. Description of the Related Art FIG. 7 is a block diagram showing an example of a conventional part program automatic diagnosis apparatus. First, of the part programs stored in the part program storage unit 1, the block data SA for one block of the part program selected for checking the command format is selected.
Is read by the 1-block data reading unit 2 and sent to the 1-block data syntax interpreting unit 3. The block data SA read by the 1-block data syntax interpreting unit 3 is recognized and interpreted as a command group of G code, M code, expression, etc., and is sent to the 1-block data syntax error checking unit 4 as syntax interpretation data SB. It The syntax interpretation data SB is read by the 1-block data syntax error check unit 4 to check each command format such as G code, M code, and expression, and to notify whether or not an error exists in the block data. The error diagnostic signal SC is sent to the syntax error check control unit 5. The error diagnostic signal SC is read by the syntax error check control unit 5, and in the case of an error diagnostic signal indicating that an error exists, the block position of the block data to be read next (hereinafter referred to as a sequence read pointer) is indicated by one block. The data is not sent to the data reading unit 2, and the execution of the part program is stopped. On the other hand, in the case of an error diagnostic signal indicating that there is no error, the instruction SD of the sequence read pointer is sent to the one-block data reading unit 2 and the above-mentioned command format check is performed. The series of command format checks described above are repeated until the program end.

[0003]

In the conventional part program automatic diagnosis apparatus described above, the execution of the part program is stopped at the block position of the block data in which the error exists by checking the command format.
In order to check the command format of the block data after the block data in which an error exists, it is necessary to repeat the operation of command format check and error correction for the number of errors, which is a great waste of labor and time. .. In addition, the operator has to store the block position of the block data in which the error exists and the content of the error or take a memo, which causes a problem that an operation error is likely to occur when the error is corrected. The present invention has been made under the circumstances as described above, and an object of the present invention is to diagnose whether or not there is an error in all block data by one command format check, and to make an error in the block data in which an error exists. It is to provide a part program automatic diagnosis device to which contents can be added.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a part program automatic diagnosis device for checking the command format of block data of a part program of a numerical control device to diagnose the presence or absence of an error in the block data. The above-mentioned object of the present invention comprises storage means for storing information specifying block data having an error and information on the content of the error, and information adding means for adding the content of the error to the corresponding block data of the part program. It is achieved by doing.

[0005]

In the present invention, since the error content is automatically added to all block data having an error, the operator simply calls the stored part program and the block position where the error occurs And the contents of the error can be confirmed quickly and accurately.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing an example of a part program automatic diagnosis apparatus of the present invention in correspondence with FIG. 7, and the same components are designated by the same reference numerals and the description thereof will be omitted. The error diagnostic signal SC sent from the one-block data syntax error check unit 4 is read by the syntax error check control unit 5, and in the case of an error diagnostic signal indicating that an error exists, the sequence read pointer SH indicates the syntax check error information storage unit. 6 is stored. At the same time, the syntax check error information SE such as the sequence name in which the error occurred, the error number, and the error message is stored in the syntax check error information storage unit 6 from the one-block data syntax error check unit 4. Then, the instruction S of the sequence read pointer
D is sent from the syntax error check control unit 5 to the one-block data reading unit 2 to perform the command format check described above, and the series of command format checks described above is repeated until the program end of the part program. When the program end command is read from the one-block data syntax error check unit 4 into the syntax error check control unit 5, the syntax check error information storage unit 6
In the syntax check error information SE stored in, the instruction SF for adding a predetermined error content after the block data at the corresponding block position is sent to the error information addition control unit 7. Then, the syntax check error information storage unit 6
The syntax check error information SE stored in is read into the error information addition control unit 7, and the error contents such as an error number and an error message are added after the block data of the block position corresponding to the sequence read pointer or sequence name in which the error occurred. SG is added.

FIG. 2 is a flow chart showing an operation example of storing syntax check error information in the part program automatic diagnosis apparatus of the present invention. First, when the selected part program is started, the syntax error check control unit 5 stores the value of the sequence read pointer SRP, the value of the variable SYE indicating the presence or absence of an error in the block data, and the error information storage stored in the syntax check error information storage unit 6. The value of the error information storage counter CT that manages the table is initialized (step S101). Then, the 1-block data reading unit 2 reads the block data indicated by the value of the sequence read pointer SRP from the part program storage unit 1 and reads 1
It is sent to the block data syntax interpreter 3 (step S1).
02). The 1-block data syntax interpreting unit 3 interprets the block data and sends the syntax-interpreting data to the 1-block data syntax error checking unit 4. The 1-block data syntax error check unit 4 checks the command format based on the syntax interpretation data and determines whether or not there is an error in the block data (steps S103 and S104).

When there is no error in the block data, the one-block data syntax error check unit 4 sends an error diagnostic signal indicating that there is no error to the syntax error check control unit 5 and the process moves to step S109 to write the block data. If there is an error, the one-block data syntax error check unit 4 sends an error diagnostic signal indicating that an error exists to the syntax error check control unit 5. The syntax error check control unit 5, which has read the error diagnostic signal indicating that an error exists, uses the sequence read pointer ETSRP [CT] (hereinafter referred to as an error sequence read pointer) indicating the block position where the error has occurred in the error information storage table. It is determined whether or not the same value as the value of the sequence read pointer SRP exists in the values (step S105), the process proceeds to step S109 if the same value exists, and an error occurs if the same value does not exist. The error sequence read pointer ETSRP [CT] of the information storage table is added to the sequence read pointer S.
The value of RP is set (step S106). at the same time,
The one-block data syntax error check unit 4 stores the syntax check error information in the syntax check error information storage unit 6 (step S107). Then, the syntax error check control unit 5 adds 1 to the value of the error information storage counter CT to prepare for taking in the next error diagnostic signal (step S108), and sets the next sequence read pointer SRP (step S109). ).

Subsequently, the syntax error check control unit 5 outputs 1
It is judged whether or not the program end command MO2 is transmitted from the block data syntax error check unit 4 (step S110), and the program end command MO2 is sent.
Is not yet sent, the process returns to step S102 and the above-described operation is repeated. On the other hand, when the program end command MO2 is sent, the syntax error check control unit 5 checks the value of the error information storage counter CT to determine whether or not there is an error in the block data of the selected part program. If there is no error (when the CT value is 0), all the processing is terminated, and if there is an error (when the CT value is 1 or more), the value of the variable SYE. To 1 (step S1
12) Further, $ FFFFFFFF, which is a value indicating the end, is written in the error sequence read pointer ETSRP [CT] of the error information storage table (step S11).
3), all processing ends.

FIG. 3 is a flow chart showing an operation example of the error information addition control unit 7, which is a main part of the part program automatic diagnosis apparatus of the present invention. First, the error information addition control unit 7 checks the value of the variable SYE (step S201), and if there is no error in the block data (SYE = 0).
Ends all processing, and if there is an error in the block data (SY = 1), the error information storage counter CT
Is initialized (step S202). Next, the error sequence read pointer E of the error information storage table
The value of TSRP [CT] is $ FFFF indicating the end
It is checked whether or not it is FFFF (step S203), and if the value of the error sequence read pointer ETSRP [CT] in the error information storage table is $ FFFFFFFF, all processing is ended.

On the other hand, the value of the error sequence read pointer ETSRP [CT] in the error information storage table is $ F.
If not FFFFFFF, the syntax check error information corresponding to the value of the error information storage counter CT is read from the syntax check error information storage unit 6 (step S20).
4), error sequence pointer ETSRP [C of the error information storage table from the selected part program
The block position of the block data corresponding to the value of [T] is searched (step S205), and the error content of the syntax check error information is added after the block data of the searched block position (step S206). Then, 1 is added to the value of the error information storage counter CT to prepare for fetching the next syntax check error information (step S207),
It returns to step S203 and repeats the above-mentioned operation.

A case in which a part program including an error as shown in FIG. 4, for example, is diagnosed using the apparatus of the present invention will be described. The part program of FIG. 4 is composed of a main program of O0010 and a subprogram of O500, and the main program includes a block of O0010.
There are 01 sequences, and there are 61 sequences in which the subprogram includes a block of O500. Main program is N
The sequence names 001 to N200 are given, and the subprograms are given sequence names N501 to N560. The part program contains an error in five block data of sequence names N030, N056, N150, N501, N530, and the order in which the errors occur is sequence names N030, N056, N501, N530, when executed from the beginning of the part program.
It becomes N150. Therefore, when the sequence read pointer is set to O0010 as the first, it becomes the execution order of each block data, so N030 is 31, N056 is 57, and N5 is
01 becomes 103, N530 becomes 133, and N150 becomes 151. When this part program is executed, each error sequence read pointer ETSRP [CT], sequence name and error content are sequentially stored in the values 0 to 4 of the error information storage counter CT of the error information storage table as shown in FIG. , Value $ FFFFFFF indicating the end to the value 5 of the error information storage counter CT at the program end
F is stored. Then, as shown in FIG. 6, after the block data indicated by the sequence read pointer ETSRP [CT], error contents and parentheses () indicating the error contents are added.

[0013]

As described above, according to the part program automatic diagnosing device of the present invention, the presence / absence of an error in all block data can be diagnosed by a single command format check, and the block position in which the error occurs and the error Since the contents can be easily confirmed, the operator can surely correct the part program in a short time, and the working efficiency can be greatly improved.
