Title:
ELEVATOR CONTROL PROGRAM REWRITING SYSTEM AND ELEVATOR CONTROL PROGRAM REWRITING METHOD
Document Type and Number:
Japanese Patent JP2023081454
Kind Code:
A
Abstract:
To provide an elevator control program rewriting system and an elevator control program rewriting method capable of preventing a system failure when control program rewriting fails and facilitating identification of a hall terminal device in which control program rewriting has failed.SOLUTION: A hall terminal device comprises: an input/output unit that receives information from a user and presents information to the user; a communication control unit that controls communication with a serial number control unit; an input/output control unit that controls the input/output unit and receives specific data from the communication control unit at the time of control program rewriting of the communication control unit; and a communication path cutoff unit that cuts off a communication path with the serial number control unit on the basis of the specific data received by the input/output control unit when an abnormality has occurred during the control program rewriting of the communication control unit.SELECTED DRAWING: Figure 1
