Abstract

Abstract This invention provides a system for recording operation data of a machine, wherein a program for converting sygnals stored through a sensor or measuring means into operation data in conformity with the increase or alteration of the sensor or measuring means due to the operation status of the machine or to the type of the component of the machine is preliminarily stored in one or separate card-type external memory or other transportable external memory. The terminal of the system is designed to allow an connection of various kinds of the sensor or measuring means. Accordingly, it is possible to conduct processing and recording of various kinds of operation data by exchanging the external memory stored with a prescribed operation data-processing program, or by changing the writing of the program. It is also possible to record operation data in the external memory stored with the operation data-processing program after the program is read out to simplify the operation of an operator.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 132 words
An operation data-recording system for a machine, which is characterized to includes; a sensor or measuring means for detecting or measuring an operation status of a machine; a terminal for storing measured signals from said sensor or measuring means; a transportable external memory written with a program for processing the measured signals from said sensor or measuring means to convert them into operation data; a reader for reading said program, which is adapted to be detachably connected with said external memory; an operation data-processing means for processing an operation data according to signals from said sensor or measuring means, which are supplied through said terminal and following a program read by said reader; and a writing means to record the operation data thus obtained through said data-processing means in said external memory.
Claim 2
Dependent Claim 132 words
An operation data-recording system for a machine, which is characterized to includes; a sensor or measuring means for detecting or measuring an operation status of a machine; a terminal for storing measured signals from said sensor or measuring means; a transportable external memory written with a program for processing the measured signals from said sensor or measuring means to convert them into operation data; a reader for reading said program, which is adapted to be detachably connected with said external memory; an operation data-processing means for processing an operation data according to signals from said sensor or measuring means, which are supplied through said terminal and following a program read by said reader; and a writing means to record the operation data thus obtained through said data-processing means in said external memory.
Claim 3
Dependent Claim 29 words
The operation data-recording system according to claim 1, characterized in that the external memory for storing the program is identical with the external memory for storing the operation data.
Claim 4
Dependent Claim 36 words
The operation data-recording system according to claim 1, characterized in that the program stored in the external memory is erased by an erasing means after being stored in the operation data processing means through the reader.
Claim 5
Dependent Claim 44 words
The operation data-recording systerm according to claim 1, characterized in that the operation data-processing means is provided with a malfunction-determining means to determine a malfunction of each of the components of the machine on the basis of the calculation of the stored operation data.
Claim 6
Dependent Claim 46 words
The operation data-recording system according to claim 1, characterized in that the operation data-processing means is provided with an optimum operation-determining means to determine an operation efficiency of each of the components of the machine on the basis of the calculation of the stored operation data.
Claim 7
Dependent Claim 36 words
The operation data-recording system according to claim characterized in that said substance further comprises uH external display output terminal for externally displaying the operation data obtained through the operation data-processing means with or without modification thereto.
Claim 8
Dependent Claim 35 words
The system according to claim 1, characterized in that the data-writer comprises a writing means which is capable of separately storing a time sequence data and a statistically processed data in the external memory-for-output data.
