Elevator maintenance terminal device

Abstract

The invention provides an elevator maintenance terminal device which fully guarantees the safety of operating personnel performing point inspection work. A control part of the maintenance terminal device applied in elevators comprises following functions: when operating personnel select execution buttons(operating with high speed, top-hitting operating, operating with low speed ) displayed in a display image of a display part, obtaining buttons (elevator car call button, start button) selected by an operating plate at the bottom of the elevator car inside the elevator car operated by the operating personnel from the control panel, elevator room buttons in elevator halls of each floor, car ceiling switches in the ceiling outside the elevator car, and the operation status of a pit switch of a pit to determine the position of the operating personnel; determining the result of the selected maintenance point inspection execution in reference to the operation execution of a storage part on the basis of the position information to limit the instruction content to the elevator control device of the control panel.

Description

technical field [0001] The present invention relates to a maintenance terminal device for an elevator that is carried and carried by workers who perform maintenance checks and is used for investigating causes of elevator failures. Background technique [0002] In the past, in the investigation of the cause of the elevator failure, the storage unit included in the elevator control device of the control panel supplemented the operation status of various equipment / devices of the elevator before and after the failure occurred, so through the operator who performed the maintenance check The maintenance terminal device reads the operation state information from the elevator control device and displays it on the display screen of the maintenance terminal device, so that the operator can easily identify the cause of the elevator failure. Therefore, the utilization of the maintenance terminal device is indispensable in the maintenance inspection work of the elevator in recent years. ...

Problems solved by technology

[0004] In the technology described in the above-mentioned Patent Document 1, by connecting the operation device for maintenance and the elevator control device by wireless communication, the operation control of the elevator can be executed by operating the operation device for maintenance at any place near the elevator. When an operation control instruction is performed by a wireless communication-based maintenance operating device, there is a problem that the elevator can be controlled by operating the maintenance operating device at any position as long as it is within the reach of radio waves in the vicinity of the elevator. The operation control is functionally convenient, but on the other hand, for example, during the investigation of the cause of the elevator failure on the beam in the hoistway, if the operator misoperates the operating device for maintenance, unnecessary operation control instructions are executed. In such a case, there is a high possibility that workers will be exposed to danger, so safety cannot be sufficiently ensured

[0005] Specifically, when the operator investigates the cause of the elevator failure, depending on the location of the maintenance spot check, there are operational controls that can be performed to maintain the personal safety of the operator and operational controls that should not be performed. For example, when the operator is standing In the case of the car outer ceiling of the car, if the elevator is driven at high speed, there is a danger of the operator being caught between the upper surface of the car and the ceiling of the hoistway or the possibility of accidentally falling. Therefore, it is customary not to allow high-speed operation control
