Embodiment Construction

[0017] Compared with the traditional electric curtain control system, the present invention is consistent with it in the power device and the curtain track, and can be used universally, but only adds a motor current detection circuit in the controller. This example introduces a specific implementation of a motor current detection circuit with simple structure and reliable operation. Please refer to figure 2 . There are many forms of current detection circuits, and the specific implementation methods are not limited thereto.

[0018] In this circuit, the mains live wire enters from terminal A and exits from terminal B, and the detected output signal is output from C to the main control circuit. Among them, D1-D4 form a diode current detection circuit, D1, D2, D4 form a forward conduction circuit, and D3 form a reverse conduction circuit; U1 is a photocoupler, which is used to isolate the strong current from the weak current, and to the microprocessor. The module transmits th...

Abstract

The invention relates to a currently-widely-used synchronous motor-based electric curtain device. A curtain position memory function and a curtain opening and closing position automatic positioning function are realized only by adding a simple circuit into a curtain control device and adopting a novel curtain automatic positioning algorithm without changing the structures of a motor power device and tracks. The electric curtain device has the characteristics of simple structure, stable and reliable performance and low cost, and can be widely applied in the fields of window curtain controllers, camera cradle heads, stage lighting, curtain controllers, advertisement signboard controllers, industrial automatic control and the like.

Description

Technical field [0001] The invention belongs to an electric curtain control device, in particular to a curtain control device capable of memorizing and automatically positioning the opening and closing positions of the curtain. Background technique [0002] The traditional electric curtain control system is generally composed of a controller, an electric power device and a curtain track (some electric curtains, such as electric roller blinds, have no track) and other parts. The controller is used to receive external control instructions (manual or remote control) to control the operation of the electric power device; the electric power device is generally composed of AC synchronous motor, deceleration mechanism, opening and closing limit switch and other components; the curtain track is responsible for hanging the curtain and turning the power The mechanical energy of the device is transmitted to the curtain to drive the opening and closing movement of the curtain. There is...
