Claims (5)

1. An acquisition means for acquiring a signal output from a pressure sensor installed in the elevator car, Based on the signal acquired by the acquisition means, a determination means determines the position of the cage and determines whether or not the cage is stopped between floors, If the determination means determines that the elevator car is stopped between floors, the transmission means transmits notification information regarding the determination result of the determination means to a management server computer installed remotely from the elevator. A remote monitoring support device characterized by being equipped with the following features.
2. The remote monitoring support device according to claim 1, characterized in that the pressure sensor is not connected to the control board of the elevator.
3. The device acquires a signal output from a pressure sensor installed in the cage of the device, Based on the acquired signal, the position of the cage and whether or not the cage is stopped between floors are determined. If it is determined that the cage is stopped between floors, the device sends notification information regarding the determination result to a management server computer located remotely . An elevator characterized by the following features.
4. The signal output from the pressure sensor installed in the elevator car is acquired. Based on the acquired signal, the position of the cage and whether or not the cage is stopped between floors are determined. If it is determined that the elevator car is stopped between floors, notification information regarding the determination result is transmitted to a management server computer located remotely from the elevator. A remote monitoring support method characterized by the following features.
5. On the computer, The signal output from the pressure sensor installed in the elevator car is acquired. Based on the acquired signal, the position of the cage and whether or not the cage is stopped between floors are determined. If it is determined that the elevator car is stopped between floors, notification information regarding the determination result is transmitted to a management server computer located remotely from the elevator. A remote monitoring support program characterized by its ability to execute processes.

Description

This invention relates to a remote monitoring support device, a remote monitoring support method, and a remote monitoring support program that assist in the remote monitoring of elevators. Traditionally, for elevators installed in multi-story buildings, maintenance was ensured by periodic inspections involving diagnostics (diagnostic maintenance work) performed by workers when a malfunction occurred. Furthermore, conventionally, there were remote elevator monitoring systems that incorporated communication functions into the control board (control device) that controlled the operation of the elevator, allowing communication between the control board and a management server computer located remotely from the elevator, thereby enabling monitoring of the elevator's status from a remote location. Furthermore, there was a conventional technology that involved connecting a terminal device equipped with communication capabilities to the elevator's control board, allowing the elevator's status to be monitored remotely via this terminal device. This enabled remote monitoring even in older elevators that were not designed for remote monitoring at the time of installation. Specifically, a related technology has existed that, conventionally, involves a system for monitoring elevator operation in which, for example, sensor information from a smart device equipped with sensors, carried by a worker, is transmitted to a central device. The central device then acquires the worker's work schedule, work location, and data acquired by the worker during the initial inspection as model data information. Based on the measurements from the sensors, the system identifies the location where elevator maintenance work should be performed and sends a signal to the smart device to alert the worker in the elevator car to any danger (see, for example, Patent Document 1 below). Japanese Patent Publication No. 2021-80076 This is an explanatory diagram showing the system configuration of the remote monitoring system.This is an explanatory diagram showing the hardware configuration of each component that makes up the remote monitoring system.This is a diagram showing the functional configuration of remote monitoring support devices.This flowchart shows the processing procedure for the remote monitoring support device. A preferred embodiment of a remote monitoring system including a remote monitoring support device according to the present invention will be described in detail below with reference to the attached drawings. (System configuration of the remote monitoring system) First, the system configuration of a remote monitoring system including a remote monitoring support device according to an embodiment of the present invention will be described. Figure 1 is an explanatory diagram showing the system configuration of the remote monitoring system. As shown in Figure 1, the remote monitoring system 100 includes a management server computer 110 and a remote monitoring support device 120. The management server computer 110 is installed, for example, in a remote location different from where the elevator 130 to be monitored is installed. Specifically, the management server computer 110 can be installed, for example, in a maintenance company 140 responsible for the maintenance and management of the elevator 130. The maintenance company 140 is equipped with a management server computer 110, as well as a telephone 142 that enables direct communication between users inside the elevator car 131 of the elevator 130 and the maintenance company 140's operator 141. The telephone 142 may be directly connected to the public voice network 101, or it may be connected to the public voice network 101 via a PBX (Private Branch Exchange: not shown in the diagram). The management server computer 110 can be implemented, for example, by a general-purpose server computer device. A terminal device 143 for operation, implemented by a personal computer or the like, may be connected to the management server computer 110. The management server computer 110 and the terminal device 143 may be installed in the same location or in different locations. The elevator 130, which is monitored by the remote monitoring system 100, is installed in a multi-story building. The elevator 130 comprises a hoistway (not shown) that penetrates each floor of the building vertically, and a car 131 for carrying people and goods. The car 131 is located within the hoistway and moves vertically up and down within the hoistway. One car 131 is provided for each hoistway. The hoistway is equipped with a drive mechanism 132 for the raising and lowering of the elevator car 131. The drive mechanism 132 can be installed, for example, at the top of the hoistway and consists of a hoisting machine 132a, a rope 132b, a counterweight 132c, and the like. Furthermore, the drive mechanism 132 is equipped with an electromagnetic brake and a speed governor (both omitted from the illustration). The elevator car 13
