PURPOSE:To free a hotel man from trouble by setting a cage to be called back corresponding to the count of passengers going to the elevator hall on lobby floor, and calling back set number of cages upon depression of front button. CONSTITUTION:When a hotel man depresses a front button 1 on lobby floor, a signal is fed from an OR element 2 to an AND element 3. Since a signal has been fed from a comparator 8, a signal 1 is fed from the AND element 3 in order to operate a radar 4, which measures the distribution of passengers going to elevator hall on lobby floor and provides a distribution state signal to a judging unit 5 which then recognizes the amount of the passengers in predetermined stages and provides a signal to a unit 6 for setting the number of elevators. The number of elevator to be called back to the lobby floor is set there and provided to a management unit 7, while simultaneously the set number is preset in the comparator 8 and the management unit 7 calls back elevator cages based on a signal fed from the unit 6 for setting the number of elevator. |
