JPH0273410A - Automatic deciding device for fixed position controller - Google Patents

Abstract

PURPOSE:To obtain an automatic deciding means for an automatic position control APC device with which the same result is always secured regardless of the operators by constituting an automatic deciding device part consisting of a personal computer and an interface and a control object part consisting of an APC device and an APC control object. CONSTITUTION:A program is previously set to a personal computer 1 to automatically decide the normal APC function data on an APC control object 2 and the data that read the process input received from the object 2 through an interface 3 in the form of a knowledge data base. Then the object 2 is set in a control start state and the states of an APC device 4 and the object 2 are inputted to the object 2 via the interface 3 when a control start command is given to the device 4. Then the normal or abnormal state of the APC function is decided based on the program stored in the computer 1. If the APC function is not normal, the defective area and the correcting method are guided.

Description

Detailed Description of the Invention (Objective of the Invention) (Industrial Application Field) The present invention relates to an automatic determination device for a fixed position stop control device that automatically makes a pass/fail judgment when adjusting a fixed position stop control device. It is something.

(Prior art) Conventionally, when adjusting a fixed position stop control device (hereinafter referred to as an APC device), data such as the control amount and operation amount was output to a pen writing oscilloscope, etc., and the operator visually read the data. A human system is used to confirm the results and then make a pass/fail judgment.

Therefore, a measuring device such as a pen-writing oscilloscope is required, and there is a possibility that the judgment results differ depending on the adjuster, and there are problems in that the required time becomes longer.

(Problems to be Solved by the Invention) The present invention uses a portable small computer (hereinafter referred to as a personal computer), a program for operating the computer, and a knowledge database to create an APC that is small in size and has no variation among adjusters. The purpose of this invention is to provide an automatic function determination device.

(Structure of the Invention) (Means and Effects for Solving the Problems) The present invention provides a computer that stores in its memory knowledge data regarding the control function of a fixed position stop control device and rule data regarding a program for automatic determination operation; It is provided between the computer and the fixed position stop control device and the controlled object, and inputs the data of the fixed position stop control device and the controlled object to the computer, and makes a judgment based on the input data, the above knowledge data and rule data. The system is equipped with a process interface that outputs data as to whether or not the adjustment of the fixed position stop control device is normal or not, thereby making it possible to automatically make reliable pass/fail judgments without operator variations with a simple configuration.

(Example) An embodiment of the invention is shown in FIGS. 1 and 2.

FIG. 1 shows the hardware configuration of the automatic determination device according to the present invention, which consists of an automatic determination device section 5, an adjusted target section 6,
Furthermore, the automatic determination device section 5 is composed of a personal computer 1 and a process interface 3, and the adjusted target section 6 is composed of an APC device 4 and an APC controlled target 2.

In FIG. 1, a personal computer 1 has in advance a knowledge database containing data on normal APCI performance of an APC control object 2 and a program (for automatically determining data read from process input from the control object 2 through a process interface 3). (including rules) are set.

When the controlled object 2 is set to the adjustment start state and the APC device 3 is commanded to start control, the states of the APC device 4 and the controlled object 2 are input to the personal computer 1 through the process interface 3, and the program (rules) in the personal computer 1 is inputted to the computer 1 through the process interface 3. ), it is determined whether the APCIFi function is normal or not. If it is not normal, depending on the phenomenon at that time, it may be defective or
Guidance will be provided on how to lower blood pressure.

FIG. 2 is a flowchart showing an example of a program built into the personal computer 1 shown in FIG. 1, in which accurate instructions regarding the quality of the APCPCl4 performance are given based on the knowledge data 7 and rule data.

〔Effect of the invention〕

As explained above, according to the present invention, there is provided an automatic determination device 1q for a ΔPC device which is simple and can be operated by anyone, and which is highly reliable and can provide the same results no matter who operates it.
