Abstract

<P>PROBLEM TO BE SOLVED: To provide an elevator door opening/closing control device capable of promptly opening/closing a door without reducing opening/closing speed in a case of the door with which wind pressure is detected last time. <P>SOLUTION: The elevator door opening/closing control device 7 is provided with a sensor 9 attached to a car 2 for detecting the wind pressure from landing 3, 4, 5 sides, and controls the opening/closing of a door 6 according to the operation of the sensor. A memory means memorizing a floor detected by the sensor is provided. When service is generated on the same floor next time, control response upon opening/closing the door is improved so as to promptly respond without reducing door speed. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

The present invention relates to an elevator door open / close control device.

Conventionally, depending on the location of the elevator, there is a problem that when the wind pressure is increased, the door is prevented from traveling and the speed is reduced. As means for solving this problem, there has been proposed one that increases the torque and speed of the door motor only when a predetermined wind pressure is detected, and prevents the door opening and closing performance from being lowered due to the wind pressure (see, for example, cited document 1).
JP-A-6-329376

  In the case of the proposed technique, wind pressure is applied to the door, and even if the door motor torque or speed is increased by the output of the wind pressure sensor that detects the pressure, there is a time delay, so it is not enough to prevent the opening and closing speed from being lowered. There was a thing.

  An object of the present invention is to provide an elevator door opening / closing control device capable of opening and closing a door quickly without causing a decrease in opening and closing speed in the case of a floor where wind pressure has been detected last time.

  In order to achieve the above object, according to claim 1 of the present invention, there is provided a sensor for detecting the wind pressure from the landing side mounted in the car, and the door opening / closing control is performed according to the operation of the sensor. In the door opening / closing control apparatus, a storage means for storing the floor detected by the sensor is provided, and a control response at the time of opening / closing the door is made so that the next time a service is generated on the same floor, the door speed is not lowered and the response is promptly performed. It is characterized by having raised.

  With this configuration, when the wind pressure is detected again at the floor where the wind pressure was detected last time, a high output is generated immediately, so that the door can be opened and closed without reducing the speed.

  Further, the present invention is characterized in that the sensor for detecting the wind pressure is constituted by a sensor for detecting the sound of the wind.

  With this configuration, the sensor can be made inexpensive.

  According to the present invention, in the case of a door whose wind pressure has been detected last time, it is possible to obtain an effect that the door can be quickly opened and closed without causing a decrease in opening and closing speed.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is an overall configuration diagram of an elevator provided with an elevator door opening / closing control device according to an embodiment of the present invention, and FIG. 2 is a flowchart for explaining the operation of the present invention.

  In FIG. 1, a car 2 in the hoistway 1 serves each floor 3, 4, 5. Although not shown in the figure, there is an elevator call button at each floor platform and a car destination button in the car. Further, landing-side doors 31, 41, 51 are installed on each floor, and can be opened by the door control device 7 and the door motor 8 by engaging with the car door 6. A sensor 9 for detecting wind pressure, wind speed, wind noise, and the like is installed in the car 2. Call information in the car, door information, the output signal of the sensor 9 and the like are connected to the elevator control device 11 by a moving cable 10.

  Next, the operation of the control device according to the present invention will be described with reference to FIG.

  During the elevator service, a call is generated by the elevator call button and the car destination button, and it is determined whether or not the call is the storage floor on which the sensor 9 was operated last time (S1). If it is the operation memory floor of the sensor 9, the elevator control device 11 transmits a speed control response change signal to the door control device 7 before the car 2 arrives at the destination floor (S4). Receiving this speed control response change signal, the door control device 7 increases the door speed control response gain in comparison with normal opening and closing (S5). As a result, a speed response gain obtained by increasing the door speed control response gain is set (S6), and a high torque output is generated in the door motor 8 via the door control device 7 (S7). 6 is immediately opened and closed at the same speed as normal, not defeated by the wind pressure (S8).

  On the other hand, if it is not the operation storage floor of the sensor 9, it is determined whether or not the line 9 has been operated after arrival (S2). If the sensor 9 has been operated, it is stored that it is the sensor operation floor (3), Thereafter, the elevator control device 11 transmits a speed control response change signal to the door control device 7 (S4). Receiving this speed control response change signal, the door control device 7 increases the door speed control response gain in comparison with normal opening and closing (S5). As a result, a speed response gain obtained by increasing the door speed control response gain is set (S6), a high torque output is generated in the door motor 8 via the door control device 7 (S7), and the door 6 does not lose the wind pressure. It opens and closes at the same speed (S8).

  On the other hand, when the sensor 9 does not operate and no signal is received, the door speed control response gain is set to a normal value (S9), and the door is opened and closed (S8) with a constant torque output (S10).

  In the present invention, when a call is made to the floor where the previous wind pressure was generated, the gain is set before arrival of the car 2, so that the door can be quickly opened and closed, and the elevator door 6 can be prevented.

It is the whole elevator block diagram provided with the door opening and closing control device of the elevator which becomes one example of the present invention. It is a flowchart explaining the operation | movement of this invention.
