Disclosed in the present invention is a resistance-encountering stop control method for a single-phase asynchronous electric motor. The single-phase asynchronous electric motor comprises a controller and an electric motor, wherein the electric motor comprises two control ends, which are respectively used for controlling forward rotation and reverse rotation; the controller comprises an MCU, and a first relay and a second relay, which are controlled by the MCU; the first relay and the second relay are respectively connected to one of the control ends of the electric motor; and one I/O port of the MCU is connected to one control end of the electric motor and the connection position is a first detection point, and the other I/O port of the MCU is connected to the other control end of the electric motor and the connection position is a second detection point. The resistance-encountering stop control method comprises the following steps: 1) a signal detection module respectively detecting voltages at a first detection point and a second detection point, performing rectification and filtering to obtain square wave voltage signals, and then outputting same to an MCU; and 2) the MCU obtaining, according to the two square wave voltage signals, a value Δt of the time difference between adjacent rising edges of the two signals, and when a change in Δt exceeds a certain range, determining that resistance is encountered.

Disclosed in the present invention is a control method for a curtain driving apparatus, comprising the following modes: 1) when an upward-moving button or a downward-moving button of a first set of buttons or a second set of buttons is pressed for a first time duration, a first motor and a second motor enter a cooperative operating mode: 1.1) if the upward-moving button of the first set of buttons or second set of buttons is pressed, an upper rail moves upward first, and then, a lower rail moves upward after a certain time interval; and 1.2) if the downward-moving button of the first set of buttons or second set of buttons is pressed, the lower rail moves downward first, and then, the upper rail moves downward after a certain time interval; and 2) when the upward-moving button or downward-moving button of the first set of buttons or second set of buttons is pressed for a second time duration, the first motor and the second motor enter an independent operating mode: 2.1) if the upward-moving button or the downward-moving button of the first set of buttons or second set of buttons is pressed individually, the upper rail is caused to move upward or downward, or, the lower rail is caused to move upward or downward, and in this case, the upper rail and the lower rail operate independently.

A manual tubular motor comprises a motor (1), a speed reduction apparatus (2) and a stroke apparatus (5). The motor (1) comprises a rotor (11) and a stator (12). The stroke apparatus (5) comprises a long shaft (51) driven by a manual mechanism (6, 6'). A clutch mechanism (4) is arranged between the motor (1) and the stroke apparatus (5). The clutch mechanism (4) comprises an upper clutch (41) fixed on one end of the rotor (11) and a lower clutch (42) that is driven by the long shaft (51) and can axially move to cooperate with the upper clutch (41). An elastic component (512) is arranged on one part of the long shaft (51) penetrating into the low clutch (42). The manual tubular motor also comprises a brake apparatus (3) arranged between the motor (1) and the speed reduction apparatus (2). The brake apparatus (3) comprises a friction plate (35) and a first brake pad (31) that is close to one side of the friction plate (35) and can be driven by the rotor (11) to separate from the friction plate (35). During a manual operation, the manual tubular motor outputs forces through the speed reduction apparatus, which saves forces.
