心地が得られる。 That is, the electric motor 4 is automatically controlled with high precision by the speed command signal V P and the deviation signal V e of the speed signal V t , and the car 8 travels in the upward or downward direction.
The load detection device 10 emits an output corresponding to the load inside the car 8. The load signal generation circuit 12 has a characteristic that the load in the car 8 and the driving direction increase on the positive side when the load is up, and increase on the negative side when the load is down, as shown in FIG. Generates a load signal Vw . The correction signal generation circuit 13 generates a correction signal according to the load signal V w , and adjusts the speed command signal V P1 at startup and acceleration when the load is up to a slightly higher value, as shown by the solid line, when the load is down. The speed command signal V P3 at the time of is corrected to be slightly lower. As a result, smooth riding comfort can be obtained as shown by the accelerations a 1 to a 3 through the uplift load, the balanced load, and the download load.

る。 However, if the output error becomes large due to changes over time in the anti-vibration rubber of the load detection device 10, appropriate correction cannot be provided, and the riding comfort deteriorates as shown by the broken lines of accelerations a 1 and a 3 . . Sometimes, in the case of an uplift load, a correction signal equivalent to a download load is applied, or in the case of a download load, a correction signal equivalent to an uplift load is applied. In such a case, the riding comfort will be worse than when there is no correction signal. On the other hand, in order to check the operation of the load detection device 10, it is necessary to load a weight into the car 8, which requires a great deal of effort on the part of the operator, so it is difficult to frequently check the operation. .

置を提供することを目的とする。 This invention is intended to improve the above-mentioned problem, and when the difference between the speed command signal, the deviation signal of the speed signal after startup, and the load signal is greater than a predetermined value, the correction based on the load and driving direction is blocked, or the car An object of the present invention is to provide an elevator control device that prevents the deterioration of riding comfort due to an abnormal load signal by preventing restart of the elevator.
以下、第４図によりこの発明の一実施例を説明
する。 An embodiment of the present invention will be described below with reference to FIG.
図中、１４は偏差信号Ｖe＝ＶP−Ｖtと負荷信
号Ｖwとを比較し、その差が所定値以上になると
出力を発生する負荷信号異常検出回路、１５は負

ある。上記以外は第１図と同様である。 In the figure, 14 is a load signal abnormality detection circuit that compares the deviation signal V e =V P -V t and the load signal V w and generates an output when the difference exceeds a predetermined value, and 15 is a load signal abnormality detection circuit. A display device 14 displays the operation, and 16 is a gate circuit that blocks application of the output of the correction signal generation circuit 13 to the speed command generation device 1 when the load signal abnormality detection circuit 14 generates an output. Other than the above, the configuration is the same as in FIG. 1.
次に、この実施例の動作を説明する。 Next, the operation of this embodiment will be explained.
かご８が一定速度で走行中の偏差信号Ｖeは、
負荷信号Ｖwと同様電動機４の負荷に比例する値
となることは周知である。したがつて、負荷信号
Ｖwが正常であれば、偏差信号Ｖeは負荷信号Ｖw
に比例（Ｖe＝kVwただしｋは比例定数）する。 The deviation signal V e when the car 8 is running at a constant speed is:
It is well known that the value is proportional to the load on the motor 4, similar to the load signal Vw . Therefore, if the load signal V w is normal, the deviation signal V e will be equal to the load signal V w
It is proportional to (V e =kV w , where k is a proportionality constant).
さて、荷重検出装置１０の出力の誤差が所定値
以上になると、負荷信号Ｖwのｋ倍と偏差信号Ｖe
との差（Ｖe−kVw）が所定値を越える。これ
で、負荷信号異常検出回路１４は出力を発生し、
ゲート回路１６により、補正信号発生回路１３か
ら速度指令発生装置１への補正信号の印加が阻止
される。その結果、かご８の起動及び加速時の速
度指令信号ＶPは、第３図の速度指令信号ＶP1〜
ＶP3の破線で示されるように、負荷に関係なく一
定となり、乗心地は加速度a1，a3の破線で示すよ
うに悪化するが、少なくとも上げ荷負荷の場合に
下げ荷負荷相当の補正信号が印加されたり、下げ
荷負荷の場合に上げ荷負荷相当の補正信号が印加
されたりして乗心地が極端に悪くなるようなこと
は避けられる。また、表示装置１５は負荷信号異
常検出回路１４の動作を表示するので、この表示
により、荷重検出器１０の再調整，修理等を必要
に応じて行うことができる。 Now, when the error in the output of the load detection device 10 exceeds a predetermined value, k times the load signal V w and the deviation signal V e
(V e −kV w ) exceeds a predetermined value. Now, the load signal abnormality detection circuit 14 generates an output,
The gate circuit 16 prevents the correction signal from being applied from the correction signal generation circuit 13 to the speed command generation device 1 . As a result, the speed command signal V P at the time of starting and accelerating the car 8 is the same as the speed command signal V P1 ~
As shown by the broken line for V P3 , it is constant regardless of the load, and the ride comfort deteriorates as shown by the broken line for accelerations a 1 and a 3 , but at least when the load is up, a correction signal corresponding to the down load is applied. It is possible to avoid situations where riding comfort becomes extremely poor due to the application of a correction signal equivalent to the upload load or the application of a correction signal equivalent to the upload load in the case of a download load. Further, since the display device 15 displays the operation of the load signal abnormality detection circuit 14, readjustment, repair, etc. of the load detector 10 can be performed as necessary based on this display.
実施例では、負荷信号異常検出回路１４が出力
を発生したとき、補正信号発生回路１３から速度
指令発生装置１への補正信号の印加を阻止するよ
うにしたが、負荷信号異常検出回路１４が出力を
発生したとき、かご８の再起動を阻止するように
してもよい。このときは、第３図の加速度a1，a3
の破線で示されるような乗心地の悪い状態での運
転を防止することができる。 In the embodiment, when the load signal abnormality detection circuit 14 generates an output, the correction signal is prevented from being applied from the correction signal generation circuit 13 to the speed command generation device 1, but when the load signal abnormality detection circuit 14 generates an output. When this occurs, the restart of the car 8 may be prevented. In this case, the accelerations a 1 , a 3 in Fig. 3
It is possible to prevent driving in uncomfortable riding conditions as shown by the broken line.
また、負荷信号Ｖwを一定速度走行中の偏差信
号Ｖeと比較して、その異常を検出するようにし
たが、加速又は減速中の偏差信号Ｖeも電動機４
の負荷に比例するので、これらと負荷信号Ｖwを
比較しても負荷信号Ｖwの異常を検出し得ること
は明白である。 In addition, the load signal V w is compared with the deviation signal V e during running at a constant speed to detect an abnormality, but the deviation signal V e during acceleration or deceleration also applies to the electric motor 4.
It is obvious that an abnormality in the load signal V w can be detected by comparing these with the load signal V w .
また、負荷信号Ｖwに応じて速度指令信号ＶP
を補正するものとしたが、かご８の乗心地や着床
の負荷による変動を小さくするために、負荷信号
Ｖwに応じて制御装置３の利得，時定数等の制御
定数を補正する場合もあり、この場合も負荷信号
異常検出回路１４を用いて上記制御定数の補正を
阻止したり、異常を表示したり、かご８の再起動
を阻止したりしてもよい。 In addition, a speed command signal V P is generated according to the load signal V w .
However, in order to reduce fluctuations due to the load on the ride comfort of the car 8 and landing, the control constants such as the gain and time constant of the control device 3 may be corrected in accordance with the load signal Vw . In this case as well, the load signal abnormality detection circuit 14 may be used to prevent correction of the control constant, display an abnormality, or prevent the car 8 from restarting.
以上説明したとおりこの発明では、速度指令信
号とかごの起動後の速度信号との偏差信号と負荷
信号とを比較し、その差が所定値以上のときは、
荷重と運転方向による速度指令信号又は制御装置
の制御定数の補正を阻止するようにしたので、負
荷信号の異常による乗心地の悪化を抑制すること
ができる。 As explained above, in this invention, the deviation signal between the speed command signal and the speed signal after starting the car is compared with the load signal, and when the difference is greater than a predetermined value,
Since the speed command signal or the control constant of the control device is prevented from being corrected depending on the load and driving direction, it is possible to suppress deterioration of riding comfort due to an abnormality in the load signal.
また、負荷信号の異常が検出されると、かごの
再起動を阻止するようにしたので、乗心地の悪い
状態での運転を防止することができる。 Further, when an abnormality in the load signal is detected, the restart of the car is prevented, so that it is possible to prevent the car from operating in a state where the ride is uncomfortable.
