Elevator control device

Abstract

The elevator control device 10 is provided with an MPU 11 for executing first processing for storing the control program input from the outside in a memory area d of a ROM 13 as a new control program; second processing for reading the control program from a memory area a of a flash ROM 12 and copying it in a memory area b as an old control program; third processing for reading the new control program from the memory area d and copying it in the memory area a; and fourth processing for reading the new control program from the memory area a and copying it in a memory area c. It becomes the new control program in which a predetermined control program executed by a computer for controlling operation of the elevator is copied in the memory area c.

Description

Elevator Control technical field The present invention relates to an elevator device controlled by a computer, and more particularly to an elevator control device in which a control program can be rewritten. Background technique In the case of general elevators, it is enough to simply call the operation mode between floors based on the car call. However, for example, when a plurality of elevators are installed in the same building such as a large building, various operation modes are sometimes required, such as restricting the floors served according to time, or wishing to prohibit car calls on specific floors. In recent years, computer control has become popular in elevators. At this time, the above-mentioned changes in the operation mode can be easily handled by simply rewriting the computer program, but on the other hand, there are also cases where abnormalities occur in the program. Therefore, in such a case, an elevator control device that rewrites the program for ...

Problems solved by technology

For example, in the prior art described in Patent Document 1, when rewriting the control program, it is necessary to temporarily stop the operation of the elevator, so there is a time limit for rewriting the control program.

In addition, for example, in the prior art described in Patent Document 2, it is necessary to prepare a dual control program storage unit and a switching device for the system, so that due to the complexity of the structure, there are problems such as increased malfunctions and higher costs.
