Abstract

PURPOSE:To speedily and efficiently call a program by calling subprograms from that different in a storage medium by means of a subprogram instruction. CONSTITUTION:When the designation of an execution program is inputted from a user I/F 10, an NC execution part 1 judges from which one among plural storage mediums 5-9 to execute. An NC program is read in a work storage part 3 for one block from one of the storage mediums. The presence or absence of the reading of the subprogram is judged in the NC program for one block, which has been read into the storage part 3. When it is present, whether a retrieval order has been designated or not is judged. when there is designation, retrieval is executed in the designated retrieval order. When there is no designation on the other hand, retrieval is executed in the order of a short input output time, which has been stored in an I/O processing part 2. In respectively retrieved subprograms, the presence or absence of the reading of the subprograms is judged in the subprograms. When it is present, the subprogram concerned is read into a main storage part 4, and the read subprogram is repeatedly processed again.

The configuration includes a cassette MT (7), an FLD (8), a bubble memory (9), and a user 1/F section (10) for inputting an execution command to the NC execution section (1).

Next, the operation of the conventional device based on the above configuration will be explained based on FIGS. 5 and 6. The human power from the user is read by the user 17F unit (10), and when the read NC program execution command is read, the NG execution unit (1) executes the NG program from the plurality of storage media (6) to (9). is searched to determine whether or not to execute this NG program. For example, when executing a certain NG program from the FLD (8), the NG execution unit (1) activates the I/O processing unit (2) and transfers the executed NG program from the FLD (8) to the work storage unit (3). Read and execute one block at a time (step 1). The NC instruction (1 block) once input from the subprogram call sequence of the conventional NG program is judged whether it is a subprogram instruction (step 2), and other than the subprogram instruction is executed normally ( Step 1). In this subprogram command, an area in the data storage section (5) containing a large number of NC programs is always searched (step 6-1).

If found in this search, the subprogram is further searched. Furthermore, when a subprogram instruction is generated from the subprogram, it is processed in the same way. If the subprogram cannot be found (step 6-1), it is treated as an error (step 8-1).

[Problem to be solved by the invention]

Conventional numerical control program execution devices are configured as described above, so when calling a subprogram from the main program in the NG device, it can only be done from the data storage unit or a specific storage medium, and control between devices is not possible. It was difficult.

This invention was made in order to solve the above-mentioned problems, and provides a numerical control program in which subprograms existing in storage areas of multiple storage media different from the main program or subprograms can be called without being aware of the storage media. The purpose is to obtain an execution device.

[Means for solving the problem] A search means sequentially searches for subprograms with the same name stored in a plurality of storage media, and when the search means searches the plurality of storage media, The time required for input/output is stored sequentially in the input/output processing means, and if the search order of the search means is specified, the time is stored in the specified order, and if the search order is not specified, the time is stored sequentially in the input/output processing means. The numerical program execution means outputs search commands to the search means in order of shortest input/output time, and the numerical control program is executed based on the subprograms searched and output using the search commands.

[Effect]

The search means in this invention searches for a target subprogram from a plurality of different storage areas of a storage medium and calls it up quickly and efficiently without the user being aware of the storage medium.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 is a block diagram of a numerical control program execution device according to the present embodiment, and FIG. 2 is an operational flowchart of the embodiment device shown in FIG.

In each of the above figures, the numerical control program execution device according to the present embodiment has a work storage unit (3),
Main storage unit (4), data storage unit (5), multiple storage media (
6) to (9) and a user I/F section (10), the conventional device, an NC execution section (1), and an I/O processing section (2) are commonly provided.
) has different functions, and an automatic search section (11) and nesting save section (12) are added.

The NC execution unit (1) is configured to include the user I/F unit (10).
), if the search order is specified and the search is performed manually, the specified search order is used, and if the search order is not specified, the input/output time is short and stored sequentially in the I/O processing unit (2) described later. A search command is sequentially outputted to the automatic search section (11), and a numerical control program is executed based on the subprograms searched and output using the search command.

The I/O processing unit (2) performs input/output processing from the corresponding storage medium (5) to (9) among the plurality of storage media (6) to (9) based on the search command from the NG execution unit (1). At the same time, the time required for the input/output processing of the search is sequentially memorized and learned.

The automatic search unit (11) sequentially searches for subprograms with the same name stored in the plurality of storage media (6) to (9) based on the search command from the NC execution unit (1). The search for subprograms with the same name means subprograms with names specified by the same address, etc., regardless of whether the contents of the subprograms are the same or not. Next, the operation of the apparatus of this embodiment based on the above configuration will be explained based on FIG. 2. First, user 17
When the execution program designation is input from the F section (10), the NG execution section (1) stores multiple storage media (5) to (9).
It is determined which one of these is to be executed, and one block of the NC program is read from any of the storage media (5) to (9) into the work storage unit (3) (step 1). For example, if it is determined that the FLD (8) is the storage medium (5) to (9), the NC execution unit (1) will control the I/O processing unit (
2) is controlled to read the designated NC program in FLD (8).

Furthermore, it is determined whether or not a subprogram is to be read in the one block of NG program read into the work storage unit (3) (step 2). If a subprogram is to be read in step 2, it is determined whether a search order has been specified (step 3). If there is a designation in this judgment, a search is performed in the designated search order.

On the other hand, if there is no designation in the above judgment, I/O! A search is performed in descending order of input/output time stored in A-Riro (2) (step 5).

In each of the subprograms searched in steps 4 and 5 above, it is determined whether there is any further subprogram to be read within this subprogram (step 6).

If a subprogram is to be read in step 6, the corresponding subprogram is read into the main memory (4) (
Step 7) The processes from step 1 onward are repeated again for this read subprogram.

On the other hand, if it is determined in step 6 that no subprogram has been read, error processing is performed (step 8), and the process ends thereafter. Furthermore, if it is determined in step 2 that the subprogram is not read, a determination is made as to whether or not it is an end code (step 9).
), the instruction ends if it is determined to be an end code, and if it is determined not to be an end code, the instruction is executed (step 1G), and the process returns to step 1 again to repeat the process. Next, another embodiment executed according to the operation flowcharts shown in FIGS. 3 and 4 will be described. FIG. 3 is a flowchart of another operation of the apparatus according to the embodiment shown in FIG. 1, and FIG. 4 is a diagram showing the priority table of the automatic search unit.
In this other embodiment, a priority table shown in FIG. 1J4 is stored in the main storage section (4), and the NC execution section (1) controls the search based on this priority table.

In other embodiment devices based on the above configuration, the processes of step 1 and step 2 are executed in the same manner as in the above embodiment. If it is determined in this step 2 that "r subprogram read", the presence or absence of priority designation is determined (step 3-1), and it is determined in step 3-1 that priority designation is "present". If so, search each storage medium (5) to (9) according to the priority order (step 4).
-1), On the other hand, if the priority specification is determined to be "none", it is determined whether the processing time is specified (step 3-1).
2). If there is a designation in this judgment, the search is performed in the order of processing time (step 4-'lk'), and if there is no designation, the search is performed sequentially.
(Step 4-3).

For each of the above searches, a search command is output from the NC execution unit (1) to the automatic search unit (l1), and this automatic search unit (1
1) starts ■/OIA Riro (2) to search each storage medium (5) to (9). Through this search, the presence or absence of a subprogram is determined (step 6), and if the corresponding subprogram is "present", it is read to the main memory (4) (step 7), and the process returns to step 1 again. The process will be repeated. On the other hand, if the subprogram is "none" in step 6, an error is handled (step 8) and the process ends.Since the nesting will be quite complex, the nesting save section is used to clearly understand the nesting state. Store the nested progress state in (12).
The structure of this nesting state is such that 1) the name of the nesting storage medium, 2) the NG program number, 2) the block number to be nested within the NG program, etc. can be stored.

Note that in the other embodiments described above, an I/O priority table is provided to determine the priority order, and the I/O IA process is executed each time an NC program is searched. When the system starts up in the I/O processing unit, the NG program list is scooped up from each I/O (storage medium) and centrally stored in the work storage unit (3) or main storage unit (4). Create a directory and run the subprogram NG
When an instruction is executed, a centralized directory may be referred to and I/O processing may be performed only once.

〔Effect of the invention〕

As described above, according to the present invention, since a subprogram is called from different storage media with one subprogram instruction, it is possible to call a subprogram from a different storage medium without changing the conventional NG program. This has the effect that an NG program stored in an external storage medium can be called quickly and efficiently. Moreover, since it is created in this manner, it is possible to create a NO program using all of many storage media, and it also has the effect of further expanding the storage execution area of the NG program.
