Abstract

PURPOSE: To improve reliability in detecting trouble of elevator, by comparing the actual change of armature current successively with standard change of armature current stored beforehand into memory, and detecting all of troubles collectively during upward and downward operation of the elevator.
CONSTITUTION: A shunt 15 is provided between generator 4 and motor 6 and it is connected to micro computor 17 which always makes communication with signal controlling means 1. When interruption of timer is caused, it is processed by the micro computer 17. For this purpose, top addresses of floor dividing reference pattern areas are set in addresses in terms of floor dividing values, and further, either of eight patterns is selected for use in consideration of operating condition. Subsequently, addresses are set by measuring current with addition of the difference value of the pattern to the address and then subtracting the previous current. Finally, it is compared with the value of reference pattern taken out from memory where address values are stored.
