縮退運転

US10175660(TOSHIBA KK [JP])
[0218] Next, when the power electronics device (AC/DC) has executed the fail-safe, the remaining power electronics devices determine the logical configuration (the master and the slave in this context) (C 104 ).
【０１６４】
  次に、電力変換装置（ＡＣ／ＤＣ）がフェールセーフしたら、残りの電力変換装置で論理構成（ここではマスタ・スレーブ）を決定する（Ｃ１０４）。

For the fail-soft (fallback operation), as briefly mentioned in the foregoing, a criterion for priority may be adopted according to which the power electronics device having the highest probability to survive at the time of abnormality is selected as the master.
フェールソフト（縮退運転）のためには、先にも少し述べたが、異常時において生きている確率が一番高い電力変換装置をマスタに選定するという優先基準を採用してもよい。

Specifically, from among the power electronics devices (DC/DC), the power electronics device connected to the power source is preferentially determined as the master over the power electronics device connected to the load.
すなわち、電力変換装置（ＤＣ／ＤＣ）の中でも、電源に接続した電力変換装置を、負荷に接続した電力変換装置よりも優先してマスタに決定する。

Further, among the power sources, the power electronics device (DC/DC) connected to the energy storage may have preference over the power electronics device (DC/DC) connected to a power generation device of renewable energy.
更に電源の中でも、蓄電池に接続した電力変換装置（ＤＣ／ＤＣ）を、自然エネルギの発電装置に接続した電力変換装置（ＤＣ／ＤＣ）よりも優先させてもよい。

 

What is 乗りかごの縮退運転 in the context of elevator control technologies?

ChatGPT:

In the context of elevator control technologies, 乗りかごの縮退運転 (degraded operation of the elevator car) refers to a mode in which the elevator operates with limited functionality due to a fault or emergency condition.

Explanation:

• 乗りかご (のりかご, "car"): Refers to the elevator car where passengers or cargo are carried.
• 縮退運転 (しゅくたいうんてん, "degraded operation" or "fail-safe operation"): Indicates a restricted or emergency operation mode that allows the elevator to function at a reduced capacity when certain failures occur.

When is 縮退運転 (Degraded Operation) Used?

It is activated when:

1. A partial failure occurs (e.g., one of the control systems, sensors, or safety devices malfunctions).
2. Power supply issues arise (e.g., limited power availability).
3. Emergency operations are needed (e.g., after detecting abnormal behavior but allowing passengers to safely exit).

Examples of 縮退運転 Modes:

• Operating at a reduced speed to ensure safety.
• Allowing only one-directional movement (e.g., moving only to the nearest floor to let passengers out).
• Disabling automatic floor selection and requiring manual operation by an elevator technician.

Alternative English Translations:

• Degraded operation of the elevator car
• Fail-safe operation mode of the elevator car
• Reduced-functionality operation of the elevator car
