MICROCONTROLLER REVISION DEVICE OF REMOTE LOCAL DEVICES FOR SIMPLY REVISING A PROGRAM WHEN AN ERROR OF THE PROGRAM OCCURS FROM EACH LOCAL DEVICE CONTROLLING AN ELEVATOR

摘要

PURPOSE: A microcontroller revision device of remote local devices is provided to conveniently revise a program of a microcontroller through data communication using a computer from a place where a control board exists and to remarkably reduce working hours and manpower. CONSTITUTION: An elevator operation system comprises an elevator(30) connected to a winch(20); a local device(31) for enabling a passenger riding in the elevator to select a target floor as a car-internal call system; a landing call system(40) arranged to each floor in a state of having local devices(41,42,43); and a control board(10) controlling operation of the elevator through data communication cables(11,12). In a microcontroller revision device of the remote local devices, a revision part(60) connected to the control board by a connection cable(65) comprises a computer terminal(61) wherein a transfer program(62) works, and a communication conversion device(63) connected to the computer terminal by a connection cable(64). Programs of each local device are revised through data communication from the computer terminal.
