Abstract

An apparatus for controlling an elevator according to the present invention has a master microcomputer having a plurality of slave microcomputers and memory means for storing in advance at least one of control data and control program necessary for the slave microcomputers, and transmitting means connected between the master microcomputer and a plurality of slave microcomputers for individually transmitting at least one of the control data and control program from the master microcomputer to the respective slave microcomputers.

Claims

1. An apparatus for controlling an elevator under a distributed control by a plurality of microcomputers comprising:

a master microcomputer and a plurality of slave microcomputers,

said master microcomputer including a microprocessor and memory which stores control data representing regulating and set values and control programs for the slave microcomputers,

each of said slave microcomputers including a slave system memory which can receive and store a control program and the control data received from said master microcomputer,

transmitting means connected between said master microcomputer and each of said plurality of slave microcomputers for transmitting control data and control programs from said master microcomputer memory to said respective slave microcomputers to be stored in said slave system memories.

2. An apparatus for controlling an elevator under a distributed control by a plurality of microcomputers comprising:

a master microcomputer and a plurality of slave microcomputers,

said master microcomputer including a microprocessor and memory which stores control data representing regulating and set values for the slave microcomputers,

each of said slave microcomputers including a slave system memory which can receive and store the control data received from said master microcomputer,

transmitting means connected between said master microcomputer and each of said plurality of slave microcomputers for transmitting the control data from said master microcomputer memory to said respective slave microcomputers to be stored in said slave system memories.

3. An apparatus according to claim 2 wherein said regulating and set value relate to acceleration and deceleration of normal speed command signals, rated speed, number of floors to a building which are not determined until an elevator is installed in a building.

5. An apparatus according to claim 3 wherein said changeable memory is an erasable programmable read-only memory.

4. An apparatus according to 3 wherein said master microcomputer memory is a changeable memory so as to be freely rewritable by an installation technician.
