JPH0286857A - Method for displaying end of working of centrifuge - Google Patents

Abstract

PURPOSE:To make it possible to easily judge whether the working of a centrifuge is finished or not by starting the display of the end of working with a display device at the time of the end and continuing the display until operation is inputted into an inputting device by a user. CONSTITUTION:When the control of a motor with a motor controlling circuit 5 is finished, the display of the end of working with a display device 4 is started and it is continued until input is received from an inputting device 1 directly operated by a user or the opening and shutting of a door is detected with a detector 2. A centrifuge brought into the end of working can easily be discriminated from running centrifuges and even a person other than the user can easily judge whether the working of a stopped centrifuge is finished or not.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for notifying the end of operation of a centrifuge, and particularly to a method for notifying the end of operation of a centrifuge, and in particular, a method for notifying the end of operation of a centrifuge. This relates to a termination notification method.

[Conventional technology]

When a conventional centrifuge finishes operating and stops, it sounds a buzzer for a certain period of time to notify the user that the operation has ended. Users can hear the buzzer to know when the operation is complete, open the centrifuge door, and remove samples.

[Problem to be solved by the invention]

In the conventional notification method described above, when multiple centrifuges are operating in the same room, it is impossible to determine which centrifuge has finished operating even if you hear the buzzer without reading the rotation speed display.
Further, when there are multiple users, there is an inconvenience that only the last user can know whether or not the stopped centrifuge has finished operating.

The purpose of the present invention is to eliminate the drawbacks of the above-mentioned conventional methods,
An object of the present invention is to provide a method for notifying the end of operation of a centrifuge by which it is possible to easily identify whether or not the operation of the centrifuge has ended.

[Means to solve the problem]

The above object is achieved by starting to notify the end of driving using the display device when the driving ends, and continuing the notification until the user's operation is input to the input device that accepts the user's operation.

[Effect]

When the motor control circuit finishes controlling the motor, the display device starts notifying the end of operation, and the input device that the user directly operates (
The operation end notification continues until input is received from the operation panel (operation panel) or the opening/closing of the door is detected, so you can easily identify the centrifuge that has finished operating from among multiple centrifuges, and also make it possible to stop the centrifuge. [Example] An example of the method of the present invention will be described below using Figs. 1 to 3. Explain in detail.

FIG. 1 is a flowchart showing an embodiment of the processing procedure of the method for notifying the end of operation of a centrifuge according to the present invention, and FIG. 2 is a block diagram showing the configuration of the centrifuge.

In FIG. 2, 1 is an operation panel that is directly operated by the user, and 2 is a door opening/closing detector.

3 is a microcomputer that performs processing according to the present invention, 4 is a display device composed of, for example, a light emitting diode, and 5 is a motor control circuit.

Next, the operation of each part shown in FIG. 2 will be explained based on the flowchart shown in FIG. First, when the motor control circuit 5 finishes motor control (operation) (step 100), the display device 4 starts notifying the completion of the operation (step 10).
1). When an input is received from the operation panel 1 (step 102) or when the door opening/closing detector 2 detects the opening/closing of the door (step 103), the operation end notification is canceled (step 104), and the process ends. Lack of key human resources (
Step: LO2), if door opening/closing is not detected, step 103), step 102, and step 103 are repeated, and the operation end notification is continued.

Although the above embodiment uses the microcomputer 3, the present invention can also be implemented by a circuit having the basic block configuration shown in FIG.

In FIG. 3, 6 is an operation panel that is directly operated by the user, and 7 is a door opening/closing detector. A signal is sent to stop the operation end notification.

Reference numeral 8 denotes a motor control circuit, which sends a signal to start an operation completion notification to the flip-flop circuit 9' when the operation is completed. 10 is a display control circuit, and a flip-flop circuit 9
Based on the output, the operation for notifying the end of a-turn is determined, and the display device 11 is controlled. Also in Figure 3, the operation end notification is
It can continue as long as the user does not operate the panel or open/close the door.

In the above explanation, the specific operation of notifying the end of driving is not based on a specific means, but may be by blinking the rotation speed display device or by lighting a revolving light.

This includes using any one or a combination of methods such as operating a sound output device such as a buzzer.

(Effects of the Invention) According to the present invention described above, the centrifuge operation completion notification continues unless the user performs some operation, so that it is possible to easily identify the centrifuge that has completed operation from among a plurality of centrifuges. This also has the effect of allowing anyone other than the user to easily know whether or not a stopped centrifuge has finished operating.
