Abstract: A control method for a conveyor device, which is applicable to a control system comprising a control terminal and one or more control nodes, each of the control nodes is in communication connection with the control terminal. The method includes controlling, by the control node that receives an operation signal, a movable device associated with the control node to reach a conveyor device to be controlled, in response to the operation signal sent by a control terminal; and determining whether to control the conveyor device to be controlled according to the indication of the operation signal, based on sensed data from a sensing device regarding the condition of an object to be conveyed on the conveyor device to be controlled.

Abstract: A safety system (105) for an elevator system (100) which includes a hoistway (104), an elevator car (102) and a plurality of landing doors (112a-f). The safety system (105) includes a first safety chain (120), a second safety chain (125) and a controller (110). The first safety chain (120) is configured to produce an even landing signal and the second safety chain (125) is configured to produce an odd landing signal. The controller (110) is configured to automatically instruct the elevator system (100) to enter a special operating mode when the production of the even landing signal and the odd landing signal indicates that the elevator car (102) is located at an even landing and an odd landing door is open, or that the elevator car (102) is located at an odd landing and an even landing door is open.

Abstract: A method of calibrating a monitoring device (20) for monitoring movement of a movable component (2, 12, 19) of an elevator system (2) comprises detecting (120) a travel time (Δtk) between a starting time (tk) and a stopping time (t′k) as well as acceleration (a(t)) of at least one movement of the movable component (2, 12, 19); determining (130, 140) a travel distance of the movable component (2, 12, 19) by integrating the detected acceleration (a(t)) twice with respect to the detected travel time (Δtk); correlating (150) the determined travel distance (sk) with the detected travel time (Δtk) to form a pair of travel time and travel distance; and storing (160) the pair of travel time and travel distance (Δtk,sk) as part of a travel profile (34).

Abstract: A device for inputting an elevator calling command and an elevator control system including the device. A device for inputting an elevator calling includes one or more button units, each of the button units including a switching element and a variable resistance circuit coupled with the switching element. The variable resistance circuit includes a button switch and a display element coupled in parallel, and a resistance value of the variable resistance circuit varies with a state of the button switch. The device further includes a control unit configured to determine a state of a corresponding button switch based on the resistance value of the variable resistance circuit within each of the button units, and to apply a pulse width modulation signal having different duty cycles onto a control terminal of a corresponding switching element based on the state as determined.
