Abstract

[Challenge] To reliably understand the status of the cage without obtaining information from the control panel. [Solution] A first measuring device 160 is retrofitted to a predetermined location in the machine room or hoistway HW of the elevator 100 to measure the atmospheric pressure at that predetermined location. A second measuring device 170 is retrofitted to the outside of the car 102 moving within the hoistway HW to measure the atmospheric pressure at the location of the car 102. Based on the difference between the first atmospheric pressure value measured by the first measuring device 160 and the second atmospheric pressure value measured by the second measuring device 170, or the amount of change in that difference, the status of the car 102 in the hoistway HW (location of the car, whether it is moving or stopped, etc.) is determined. This allows for easy retrofitting and reliable confirmation of the status of the car 102 without obtaining information from the control panel. [Selection Diagram] Figure 1

Description

This invention relates to an elevator that determines the status of the elevator car in the hoistway. Conventionally, there was a technique for detecting the vertical relative position of the elevator car and the maintenance worker based on the difference between a first atmospheric pressure measured by a first atmospheric pressure measuring unit attached to the elevator car or counterweight, and a second atmospheric pressure measured by a second atmospheric pressure measuring unit installed in a terminal device carried by the maintenance worker (see, for example, Patent Document 1 below).

A preferred embodiment of the elevator according to this invention will be described in detail below with reference to the attached drawings. (Elevator configuration) First, the configuration of the elevator according to the embodiment of this invention will be described. Figure 1 is an explanatory diagram showing the configuration of the elevator according to the embodiment of this invention. In Figure 1, the elevator 100 according to this embodiment of the invention can be realized, for example, by a rope-type (traction-type) elevator 100. The elevator 100 is installed, for example, in a building such as a multi-story building. Each component of the elevator 100 is driven and controlled by the control panel 101. The control panel 101 is connected to each component of the elevator 100 and, for example, outputs signals to each component of the elevator 100, so-called "down signals." The control panel 101 also receives signals from each component of the elevator 100, so-called "up signals." Furthermore, the control panel 101 is connected to the management server computer 150 via a network such as the Internet (the network NW shown in Figure 3, described later). The management server computer 150 is installed in a remote location, different from the location where the elevator 100 to be monitored is installed. The management server computer 150 can be installed, for example, by a maintenance company responsible for the maintenance and management of the elevator 100. The external device may also be this management server computer 150. The control panel 101 transmits an alarm signal to, for example, the management server computer 150. The control panel 101 outputs an alarm signal, for example, when it detects a fault in the elevator 100 or when the operating mode of the elevator 100 changes. Furthermore, the control panel 101 receives various instructions, such as instructions to execute diagnostic operations, transmitted from the management server computer 150, and outputs a downward signal corresponding to the received instructions to each component of the elevator 100. The diagnostic operation is performed by outputting signals from the control panel 101 to each component of the elevator 100, instructing them to operate in a predetermined order, and then outputting signals from the control panel 101 to the management server computer 150 indicating whether each component operated normally according to the output signals. The management server computer 150 outputs instructions to execute the diagnostic operation periodically (for example, at the end of each month). By connecting the control panel 101 and the management server computer 150 via the Internet rather than a public voice network such as a telephone line, delays in
