Abstract

PURPOSE:To observe work under normal environment by automatically judging the seating by a seating sensor, processing in time base by a computer and outputting a work sampling graph. CONSTITUTION:The seating sensor 1 has a function judging whether an observed man executes work or not, and the information is transmitted to a personal computer 3 by a connection cable 2. The program which collects and accumulates information transmitted from the plural seating sensors 1 is operated at all times on the personal computer 3 and it outputs the work sampling graph 5 processed in terms of the time base after prescribed time from a printer 4. When the observed man 7 sits to a terminal 6, the seating sensor 1 senses that the observed man 7 is seated and the information is transmitted to the personal computer 3 through the connection cable 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic work measuring system, and more particularly to a system for creating a work sampling graph used for time study of an IE method.

[0002]

2. Description of the Related Art Conventionally, in order to measure work and create a work sampling graph (Gantt chart) based on this type of time research method, several observers each have a decimal minute stopwatch and perform work measurement. The measurement results were entered on the time study form and posted on the work sampling graph form.

[0003]

In the conventional work measurement and work sampling graph creation method using a decimal minute stopwatch by several observers, an observer is required for each model and machine of the object to be analyzed. Therefore, the difference between the individual observer and the individual appears in the measured value. Also, due to human observation, the observed person may move or work differently from usual, or may be in an excessively mental state. That is, there is a problem that normal work observation cannot be performed.

[0004]

The automatic work measuring method of the present invention is provided for each observation object and determines whether or not the observation object is in operation depending on whether or not a worker is seated and generates determination information. And a computer for inputting the determination information from the seating sensor, processing it along the time axis, and outputting it as a work sampling graph showing the work time of the observation target.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention.
In FIG. 1A, the seating sensor 1 has a function of determining whether or not the observed person is working, and the information is transmitted to the personal computer 3 by the connection cable 2. On the personal computer 3, a program for collecting and accumulating information sent from a plurality of seating sensors 1 at any time is running, and after a certain time, the work sampling graph 5 processed on a time axis is output from the printer 4. To do.

FIG. 1 (B) shows that a seating sensor is installed in the terminal 6 in order to observe the work of the terminal 6. When the observed person 7 sits at the terminal 6, the seating sensor 1 detects that the observed person 7 is sitting and transmits the information to the personal computer 3 via the connection cable 2.

FIG. 2 is a diagram showing an example of the work sampling graph 5 output from the printer 4. In the graph, t1 to t10 represent time, and A, B, C, and D represent respective machines to be observed such as terminals. The time axis changes from top to bottom, and the shaded area is the time when the observer is seated on each machine and working. Based on this work sampling graph, the operating rate can be easily calculated by a method such as the WS method.

[0009]

As described above, according to the present invention, the seating sensor automatically determines that the worker is seated on the observation object and is working, and the computer performs time-based processing to perform work sampling graph. By outputting, there is an effect that it is not necessary to have an observer for each machine, the observed worker is also freed from mental pressure, and work observation can be performed in a normal environment.
