JPH06286951A - Announcing device for elevator - Google Patents

Abstract

PURPOSE:To reduce the occurrence of mischievous operation of the call button of an interphon by providing a circuit wherein in a case a call button is operated when abnormality of an elevator is not detected by an abnormality detecting device, a door is closed and opening of a door is blocked. CONSTITUTION:When a passenger in a car 2 operates a call button 2A during opening of a door 2C, a normally-opened contact 8a1 is closed since an elevator is normal. A circuit of P-8a1-7a2-9-N is formed and a mischief detecting relay 9 is energized. A circuit of P-9a1-10b1-11-N is formed, a door closing command relay 11 is energized and door closing operation is performed until a normally- closed contact 10b1 is released, i.e., the door 2C is completely closed. Further, a circuit of P-7a3-9a2-Ia-3-N is formed, a communicating device 3 is started, and the telephone set 5A of a monitoring center 5 is called. When a speaking circuit of 2B-3-4-5A is closed, a signal inputted to a terminal Ia, i.e., a signal for a fact that announcement is made by a mischief is transmitted.

Description of the Related Art A telephone such as a telephone or an intercom is usually installed in an elevator car, and is connected to a telephone such as a telephone or an intercom connected to a management room in a building. When the elevator breaks down and the passenger is trapped in the car, the passenger contacts the management room by the above-mentioned telephone and asks for rescue. Recently, an elevator monitoring center has been installed at an elevator maintenance company to monitor elevators for abnormalities in each area and to make calls to passengers trapped in a car via a telephone line. Has become.

あった。However, since the call button of the elevator notification device is arranged at a position where anyone can easily use it, it is sometimes used even when it is not broken due to mischievous passenger mischief, and each time, The staff of the monitoring center must deal with this, and there is a disadvantage that most of the burden on the staff of the monitoring center is spent on this.
As described in Japanese Patent No. 200682, when the communication device of the car is operated only under the condition that the door of the elevator is closed, there is a device connected to the communication device of the monitoring center.

出し釦を有効とするものでは効果がなかった。In the above-mentioned prior art, the call button of the intercom is effective only when the door is closed. However, since a person who plays a trick can call the intercom regardless of whether the door is opened or closed, the effect cannot be expected. The mischief is carried out at night in apartments and condominiums, and a survey of this person revealed that it was limited to several specific drunken people, and this drunken man played mischief regardless of whether the door was opened or closed. The mischief was not effective when the call button was activated only when the door was closed as described in the prior art.

のである。In order to achieve the above object, the present invention provides an abnormality detection device for detecting an abnormality in an elevator, a call button for an intercom installed in a car of an elevator, and this call button. When you press and hold for a predetermined time,
In an elevator notification device connected to a monitoring center for remotely monitoring the abnormality of a plurality of elevators via a communication line, when the abnormality detection device does not detect the abnormality of the elevator, if the call button is operated, the door is opened. It is provided with a door opening prevention circuit that closes and prevents the door from opening.
