ABSTRACT:
The respective status signals of an existing relay type elevator and an electronic elevator are loaded by a group-supervisory computer, together with hall call signals, and operation commands according to which the elevators are to respond to the hall call signals are generated and sent to the existing relay type elevator and the electronic elevator.
Consequently, even in a case where one or more elevators in a relay type elevator group in operation has/have been replaced with an electronic elevator or electronic elevators, the service of elevator group supervision is prevented from lowering. Moreover, the group supervision service can be enhanced by increasing the use of an electronic elevator already and combining it with relay type elevators in operation.
