PROBLEM TO BE SOLVED: To provide a configuration which does not allow an excessive control voltage to be applied to an elevator control circuit in the case where drop or increase of power supply of a microcomputer for controlling an elevator is detected.SOLUTION: An elevator control power monitoring device is provided which includes: at least two or more independent control power supplies provided at a control board of an elevator; at least two or more monitoring circuits connected to each independent control power supply, for mutually monitoring drop or increase of the voltage of each independent control power supply and for outputting a monitoring result of the independent control power supply; an elevator control circuit in which power is supplied from one independent control power supply out of the independent control power supplies, and which outputs control information for normally operating the elevator based on the monitoring result of the voltage of the independent control power supply; and an elevator power supply control circuit in which the power is supplied from the other independent control power supply out of the independent control power supplies and which turns on or cuts off the power supply of the elevator based on the monitoring result of the voltage of the independent control power supply and the control information from the elevator control circuit.
【課題】エレベータを制御するマイコンの電源の低下または上昇を検出した場合に、エレベータ制御回路に過大な制御電圧を印加させない構成とする。【解決手段】エレベータの制御盤に設けられた少なくとも2つ以上の独立制御電源と、各独立制御電源に接続し、各独立制御電源の電圧の低下または上昇を相互に監視して、前記独立制御電源の監視結果を出力する少なくとも2つ以上の監視回路と、前記独立制御電源のうち一の独立制御電源から電源を供給され、前記独立制御電源の電圧の監視結果に基づいて、前記エレベータを正常運転させるための制御情報を出力するエレベータ制御回路と、前記独立制御電源のうち他の独立制御電源から電源を供給され、前記独立制御電源の電圧の監視結果及び前記エレベータ制御回路からの制御情報に基づいて、前記エレベータの動力電源を投入または遮断するエレベータ動力電源制御回路と、を備えることを特徴とする、エレベータ制御電源監視装置が提供される。【選択図】図1
