Car information indicating apparatus |
摘要 |
A car information indicating apparatus for elevator cars displays elevator movement information by using signal relaying devices that do not include separate CPUs. Each signal relaying device is capable of receiving/processing data representative of car information from the car controller and of transmitting to a plurality of car position indicators on each floor landing, resulting in an elevator system that has a more simple construction and reduces cost.
