次に、この実施の形態の動作を図2及び図3を参照して説明する。
(1)戸閉動作開始前(図2)
ステップS1で戸閉開始前に、乗車検出センサが動作しているか、換言すれば障害物の存在を検出しているかを判定する。この乗車検出センサが動作していないと判定すると、ステップS7へ飛んで通常にかご戸3を閉める。
Next, the operation of this embodiment will be described with reference to FIGS.
(1) Before start of door closing operation (Fig. 2)
In step S1, before starting the door closing, it is determined whether the boarding detection sensor is operating, in other words, the presence of an obstacle is detected. If it determines with this boarding detection sensor not operating, it will fly to Step S7 and will close car door 3 normally.
乗車検出センサが動作していると判定すると、ステップS2へ進んで、戸閉動作を阻止するとともに、アナウンス装置7から、例えば、「ドアが閉まります。」「ドアから離れてください。」などのメッセージを発報する。ステップS3でステップS2の戸閉前注意アナウンス終了時、再度乗車検出センサが動作しているかを判定し、動作していないときは、ステップS7で通常戸閉をする。乗車検出センサの動作が継続しているときは、ステップS4へ進み、例えば「ドアが閉まります。」などのメッセージを発報する。   If it is determined that the boarding detection sensor is operating, the process proceeds to step S2 to prevent the door closing operation, and from the announcement device 7, for example, “The door is closed.” “Please leave the door.” Issue a message. In step S3, at the end of the caution announcement before door closing in step S2, it is determined again whether the boarding detection sensor is operating. If not, the door is normally closed in step S7. When the operation of the boarding detection sensor continues, the process proceeds to step S4, and a message such as “door closes” is issued.
ステップS5でステップS4の戸閉警告アナウンスが終了するのを待ち、アナウンスが終了すると、ステップS6へ進み、戸閉警告音、例えば「ブーブーブー…」をアナウンスするとともに、戸閉動作に移行する。このとき、戸閉速度は通常よりも低速度とする。かご戸3が全閉すると、警告音の鳴動は止む。ここで、ステップS1,S2は戸閉阻止手段及び第1の警報手段を、ステップS3〜S7は第1の戸閉制限手段を構成している。   In step S5, the process waits for the door closing warning announcement in step S4 to end. When the announcement ends, the process proceeds to step S6, where a door closing warning sound, for example, “boo boo boo ...” is announced, and the door closing operation is started. At this time, the door closing speed is lower than usual. When the car door 3 is fully closed, the warning sound stops. Here, steps S1 and S2 constitute door closing prevention means and first alarm means, and steps S3 to S7 constitute first door closing restriction means.
このようにして、戸閉開始前に乗車検出センサが動作していると、注意アナウンスを発報するようにしたため、出入口柱1やかご戸3近傍に存在する人体等の障害物に、かご戸3が衝突することを未然に防止することが可能となる。また、乗車検出センサの動作が継続していると、戸閉警告音とともに、戸閉速度を低速度にして戸閉するようにしたため、極力運転効率を低下させないようにすることが可能となる。   In this way, when the boarding detection sensor is operating before the door is closed, a caution announcement is issued, so that an obstacle such as a human body in the vicinity of the doorway pillar 1 or the car door 3 3 can be prevented from colliding with each other. Further, if the operation of the boarding detection sensor is continued, the door closing speed is lowered and the door closing operation is performed together with the door closing warning sound, so that it is possible to prevent the operation efficiency from being lowered as much as possible.
(2)戸閉動作開始後(図3)
ステップS11で停止階で戸閉動作開始後に、乗車検出センサが動作しているかを判定する。この乗車検出センサが動作していないと判定すると、ステップS13で通常にかご戸3を閉める。
乗車検出センサが動作していると判定すると、ステップS12へ進んで、かご戸3を停止させる。これは、エレベーター制御装置8からの戸開指令信号8a及び戸閉指令信号8bの両信号を出力しないことで実現できる。所定時間(この実施の形態では3秒間)経過後、戸閉速度を通常速度から低速度にするとともに、戸閉中警告アナウンス、例えば「ピーピーピー…」を戸全閉まで発報する。
(2) After the door closing operation starts (Fig. 3)
In step S11, it is determined whether the boarding detection sensor is operating after the door closing operation is started on the stop floor. If it is determined that the boarding detection sensor is not operating, the car door 3 is normally closed in step S13.
If it determines with a boarding detection sensor operating, it will progress to Step S12 and will stop the car door 3. This can be realized by not outputting both the door opening command signal 8a and the door closing command signal 8b from the elevator control device 8. After a predetermined time (3 seconds in this embodiment) elapses, the door closing speed is changed from the normal speed to a low speed, and a door closing warning announcement, for example, “PPP ...” is issued until the door is fully closed.
ここで、ステップS11,S12は第2の戸閉制限手段を、ステップS12は第2の警報手段を構成している。
このようにして、戸閉開始後に乗車検出センサが動作すると、戸閉を停止し、所定時間後戸閉警告音とともに、低速度で戸閉動作に移行するようにしたため、駆込み乗車、突然の降車等による不意の戸反転動作が生じて、出入口柱1とかご戸3のすき間に、人体等の障害物が引き込まれることを未然に防止することが可能となる。
Here, steps S11 and S12 constitute second door closing limiting means, and step S12 constitutes second alarm means.
In this way, when the boarding detection sensor operates after the start of door closing, the door closing is stopped, and after a predetermined time, the door closing warning is sounded and the door closing operation is started at a low speed. It is possible to prevent an obstacle such as a human body from being drawn into the gap between the doorway pillar 1 and the car door 3 due to an unexpected door reversal operation caused by the above.
実施の形態2.
この実施の形態は、実施の形態1の構成を乗場出入口に適用したものである。
すなわち、かごの出入口柱1及びかご上板2を乗場出入口に設置される乗場三方枠に置換し、かご戸3を乗場戸に置換することにより実現可能であり、実施の形態1と同等の効果を期待することが可能となる。
Embodiment 2. FIG.
In this embodiment, the configuration of the first embodiment is applied to a landing entrance.
That is, it can be realized by replacing the car doorway pillar 1 and the car upper plate 2 with a landing three-way frame installed at the landing doorway, and replacing the car door 3 with the landing door, and has the same effect as the first embodiment. Can be expected.
