Description

  The present invention relates to an elevator apparatus and a floor determination method for determining a car floor.

  At the time of elevator installation work, an operator rides on a car and repeats up-and-down traveling by manual operation to install equipment and perform wiring in the hoistway. Here, since the equipment to be installed in the hoistway is determined for each floor, it is required that the worker can easily know the current car position (floor).

  In a general elevator, in order to detect a car position, a floor sensor is attached to the car, and a floor plate is attached to each floor. Further, when the car travels up and down and the floor sensor detects the floor plate, the floor to which the floor plate is attached can be specified as the current car position (for example, Patent Document 1). reference).

  However, the floor sensor is vulnerable to shocks. If the floor sensor is installed during the elevator installation work, the floor sensor may break down or be damaged due to vibration or welding current sneaking during the installation work. There is a fear. Therefore, the floor sensor is generally attached at the final stage of the installation work.

  Therefore, during the elevator installation process until the floor sensor is installed, there is nothing to inform the car position, so the worker always remembers which floor the car is currently in, or the current car In order to know the location, it is necessary to go to the elevator hall and check the floor.

  Another way to identify the car position is to detect the car floor by detecting the distance (height) from the pit bottom of the elevator using a laser distance meter, or in the hoistway There is one in which a plate (floor display plate) for displaying a floor is installed, and an operator reads the floor display plate to determine the floor of the car.

However, the prior art has the following problems.
That is, if the worker memorizes the car position, there is a possibility that the car position may be mistaken, and if the worker once goes to the elevator landing to know the car position, the efficiency of the elevator installation work is reduced. There's a problem.

  In addition, when using a laser rangefinder, the distance accuracy decreases due to the influence of dust and debris, and when the installation jig or equipment is placed under the hoistway, etc. There is a problem that an error occurs. Furthermore, when installing the floor display plate, it is not economical to install it only for installation work, and when there are many floors, it is a difficult task to install only the floor display plate. There is a problem.

  The present invention has been made to solve the above-described problems, and provides an elevator apparatus and a floor determination method by which an operator can accurately determine the floor of a car in the middle of elevator installation work. The purpose is to obtain.

Elevator apparatus according to the present invention is placed on the elevator car, the car is vertically traveling by a manual operation by an operator on the car, the worker on the car to allow determining floor of the car during the working operation Elevator device that has equipment, the operation equipment corresponds to the pressure measurement unit that measures the ambient pressure, the altitude calculation unit that calculates the altitude from the ambient pressure measured by the pressure measurement unit, and the elevation of the hoistway The floor number stored in advance, the floor conversion unit that converts the altitude calculated by the altitude calculation unit into a floor number by referring to the table, and the floor number converted by the floor conversion unit And a notification unit for notifying the user.

A floor determination method according to the present invention is a floor determination method that enables an operator on an elevator car to determine the floor of a car during work, and includes a barometric pressure measuring step for measuring the atmospheric pressure around the car, A step of calculating an altitude from the measured ambient pressure, and converting the calculated altitude into a floor number with reference to a table in which floor numbers corresponding to the altitude of the hoistway are stored in advance. A conversion step and a notification step of notifying the converted floor number to the outside.

According to the elevator apparatus and the floor determination method according to the present invention, the atmospheric pressure measurement unit (atmospheric pressure measurement step) measures the ambient atmospheric pressure, and the altitude calculation unit (altitude calculation step) calculates the altitude from the measured ambient atmospheric pressure. The floor conversion unit (floor conversion step) converts the calculated altitude into a floor number with reference to a table in which floor numbers corresponding to the altitude of the hoistway are stored in advance, and a notification unit ( The notification step) notifies the converted floor number to the outside.
Therefore, the worker can accurately determine the floor of the car during the elevator installation work.
