Abstract

PURPOSE:To facilitate addition or alteration of a general purpose program by giving a control program which has a program control table on which plural kinds of the name of an execution program, the start time of the program and termination time are registered and which arbitrarily starts/stops the desired execution program to a general purpose OS-side. CONSTITUTION:The program control table 1 on which plural kinds of data 2 on the name of the execution program, the start time and termination time of the program and sampling time required for the execution of the program are registered is given and update data 2 is taken out from the table 1 if necessary. The control program which arbitrarily starts/ stops the desired execution program in accordance with data is given to the side of the general purpose operating system (OS). When the general-purpose program is added or altered, only the update of the program control table 1 and the preparation of the program to be added and altered are required and only the program to be added is required for the object of design and debug. Thus, required work and time are shortened.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides an execution program in a man-machine interface device that has a general-purpose OS (operating system) and a control OS (operating system) and is capable of starting multitasking. This is related to the management method.

[Conventional technology]

In such conventional man-machine interface devices, management such as starting and stopping of execution programs was mainly performed by the control OS.

For example, when writing data to an external storage device such as a floppy disk, data cannot be written by a command on the control OS side alone, but required parameters are passed to a program on the general-purpose OS side to perform the writing.

[Problem to be solved by the invention]

As mentioned above, in the conventional technology, a general-purpose program (execution program) cannot be started independently and arbitrarily on the general-purpose OS side, so when trying to replace the general-purpose program to be executed with another one, the general-purpose OS side There was a problem in that it was not easy to modify and change both the control OS and the control OS.

An object of the present invention is to solve such problems, to enable a general-purpose OS to select any desired general-purpose program and start it arbitrarily at any time, and to replace the general-purpose program to be executed with another one. An object of the present invention is to provide a program management method that eliminates the need for the complicated work that was conventionally necessary when doing so.

[Means to solve the problem]

In order to achieve the above object, the present invention has a program management table in which multiple types of data are registered, including the name of an execution program (general-purpose program), the start time and end time of the program, and the sampling time necessary for executing the program. The general-purpose OS is provided with a control program that extracts update data from the table as necessary and enables a desired execution program to be started and stopped as desired.

[Effect]

As a result, since the control program on the general-purpose OS side has a program management table, it is possible to calculate the start time (next start-up time) of the general-purpose program registered therein according to the contents of the table. Furthermore, the termination of the program can also be determined by comparing the next activation time and the termination time.

〔Example〕

FIG. 1 shows an execution program (
It has a program management table in which multiple types of data are registered, including the name of a general-purpose program, the start time and end time of the program, and the sampling time required to execute the program, and update data can be updated from the table as necessary. 11 is a flowchart showing a control program that extracts a program and can arbitrarily start and stop a desired execution program (general-purpose program) according to the program.

In step SIO in the same figure, the program management table is a program management table in which a plurality of types of the above-mentioned data are registered.

FIG. 2 is an explanatory diagram of such a program management table. In the figure, the management table includes a program (1
) to program (n), and each management information consists of a program name, a program start time, a program end time, and a sampling time.

Returning to FIG. 1, in step SIO, the program management table update means to select and update one new piece of management information from the management information of program (1) to program (n). means. When the need arises, the update flag may be turned on in the previous step S9.

In "program start" in step S20,
A general-purpose program corresponding to the selected program name will be started.

No further explanation is necessary regarding FIG.

〔Effect of the invention〕

Conventionally, when adding a general-purpose program to be executed, it was necessary to change the programs on two OSes (general-purpose OS and control OS) at the same time, which required a lot of work and time to create the program. According to the present invention, all that is required is to update the program management table and create programs to be added, and only the programs to be added are subject to design and debugging, so the required work and time can be significantly reduced. There are advantages.

Claims (1)

[Claims] 1) Have a program management table in which multiple types of data are registered, including the execution program name, the start time and end time of the program, and the sampling time necessary for executing the program, and update data from the table as necessary. An arbitrarily activated program management method characterized in that a general-purpose operating system has a control program that can be retrieved and arbitrarily started and stopped according to the desired execution program.
