Problems solved by technology

[0003] In the above-mentioned control methods, the light-controlled blinds sense the intensity of indoor light by installing photosensitive sensors indoors, such as the Chinese invention patent "A Smart Blind Control System and Method" (application number: CN201410624059. The sensor senses the light intensity to adjust the shutter blades, but because the light intensity signal output by the sensor must be sent to a controller such as a microcontroller for processing, in order to avoid the connection between the sensor and the microcontroller being too long, the photosensitive sensor will be installed next to the shutter body or even It is the circuit board of the shutter controller. Therefore, the limitation of the installation position and quantity of the photosensitive sensor makes the light intensity data collected by the sensor and the actual light intensity of the environment have errors, so the practicability of the light-controlled blinds is low, and the market share is not high. high
Compared with other control methods, wireless remote control has always been the most commonly used control method. Users can control the opening and closing angle of curtain blades through the remote control, which is easy to operate, flexible and practical. The disadvantage is that the remote control is easy to be damaged or lost, and it is not easy to configure a new remote control. , In addition, the remote control needs to be powered by batteries, which does not use energy saving and environmental protection

Embodiment

[0020] Such as figure 1 Shown, in the embodiment of the present invention, the intelligent shutter control system based on the bluetooth control of the Android mobile phone comprises an Android mobile phone (1), a bluetooth receiving module (2), a single-chip processor (3), a motor drive module (4), a DC power supply ( 5) and DC motor (6). The Android mobile phone (1) has a built-in Bluetooth module (1.1) and Bluetooth APP (1.2), the Bluetooth receiving module (2) is connected to the serial port of the single-chip microcomputer (3), the output port of the single-chip microcomputer (3) is connected to the motor drive module (4), and the motor drive module ( 4) Connect the DC power supply (5) and the DC motor (6) respectively.

[0021] Android mobile phone (1) is a smart phone running Android 4.3.1 and above operating system, the Bluetooth module (1.1) supports 4.1 protocol, and the Bluetooth APP (1.2) is Qpp provided by Zhou Ligong Company, just open and run this application ...

Embodiment approach 1

[0030] Embodiment 1: The blinds are initially open, such as image 3 As shown in (a), open the Android mobile phone and send the character "0" at this time, and the single-chip processor (3) outputs the TTL logic control level "IN1=1, IN2=0, ENA=1" to the motor drive module (4), OUT1 and OUT2 of the module (4) output a large current to drive the DC motor (6) to rotate forward clockwise, and the blinds begin to flip and close. When the mobile phone sends out the character "0" continuously, the curtain will flip continuously until it is fully closed; stop sending the character, and the curtain blades will stop flipping. image 3 (b) shows the curtain blade rotated by 45°.

Embodiment approach 2

[0031] Embodiment 2: The blinds are initially closed, such as image 3 As shown in (c), at this moment, the Android mobile phone is opened and the character "1" is sent, and the single-chip processor (3) outputs the TTL logic control level "IN1=0, IN2=1, ENA=1" to the motor drive module (4), OUT1 and OUT2 of the module (4) output a large current to drive the DC motor (6) to reverse counterclockwise, and the blinds begin to turn and open. When the mobile phone sends out the character "1" continuously, the curtain will continue to flip until it is fully opened; stop sending the character, and the curtain blades will stop turning.

Abstract

The invention discloses an intelligent shutter control system based on Android mobile phone Bluetooth control. The system comprises an Android mobile phone, a Bluetooth receiving module, a single-chipmicrocomputer processor, a motor driving module and a direct current motor. The motor driving module is used for driving a motor to control the rotation angle of a shutter blade. Bluetooth and a Bluetooth APP are arranged in the Android mobile phone. The Bluetooth receiving module is connected to the serial port of a single-chip microcomputer. After mobile phone Bluetooth and the Bluetooth receiving module are successfully paired, control data for adjusting a blade angle is sent to the serial port of the single-chip microcomputer through using wireless communication. After the data is processed by the single-chip microcomputer, a corresponding driving control signal is generated and output to the motor driving module. The direct current motor is driven to rotate forwardly, rotate reversely and brake. The opening and closing rotation angle of a shutter curtain blade is controlled. The system remotely controls the opening and closing of the shutter curtain blade through the mobile phoneBluetooth and the APP so that the limitation of a special remote controller is broken through, and the new method of household intelligent control is provided. A control mode in the invention has high applicability, a low price and simple operation, and is energy-saving and practical.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to an intelligent shutter control system based on Bluetooth control of an Android mobile phone. Background technique [0002] The style of blinds is simple and bright, practical and convenient, and they are very popular curtains. Different from traditional soft curtains, venetian blinds are composed of strip-shaped blades of different materials. These blades are connected in series by pulling ropes. The opening and closing angle of each blade can be adjusted, which can more accurately adjust the degree of natural lighting in the room. At present, electric shutters are widely used in family residences, playgrounds, office buildings and other places. Its drive system consists of a control system, an electric shutter motor, a rope reel and a mechanical limiter. The control method of the system is: Common wire switch control, wireless remote control, timing control, wind, rain, light...
