Computer control system for selecting a desired control program from a plurality of control programs |
摘要 |
A control device for an elevator system in which an operating program for the elevator can readily be changed by the addition of a read-only memory containing only instructions needed for modifying control signals computed by a standard program. To the standard computerized control device of an elevator system is added a further read-only memory and a further random access memory. The read-only memory stores programs which modify the computational results produced as a result of executing the standard programs. The computational results produced by executing the standard programs are stored in the added random access memory, there modified as a result of executing the special program stored in the added read-only memory, and then transferred to another random access memory for transfer to the devices which perform the direct control of the elevator cage of the system.
