It enables adjustments to the light bulb's switching and brightness through software programming. Intelligent home furnishing refers to the integration of advanced computer technology, network communication, and comprehensive wiring techniques to organically combine all systems related to family life. This holistic management aims to enhance comfort, safety, and efficiency in domestic environments. With the advancement of lifestyle improvements and electronic technology, intelligent home furnishing is increasingly becoming part of daily life. Users are moving beyond traditional manual switches for controlling lights, leading to the development of a telecontrol system that offers high-level illumination control at a low cost, providing high quality, flexibility, and convenience. The infrared remote control command is currently the most widely used means of communication and remote control. This method utilizes infrared rays (also known as infrared light) to transmit control signals, enabling remote operation of various functions. The command signals are emitted by an infrared projector, received by a receiver that processes and identifies the signals, and ultimately executes different functions through a corresponding control chip. The infrared rays projector consists of a key set, a signal generating circuit, a frequency modulator circuit, a driving circuit, and an infrared emitter. When a key is pressed, the command signal generating circuit produces the necessary control command signal. The command signals are distinguished by their frequency characteristics and code block characteristics, with different frequencies or coded telecommunications representing different commands. These command signals undergo frequency modulation, which drives the infrared emitter to transmit the command signal. The infrared receiver consists of a receiving device, an amplifying circuit, a demodulation circuit, and a command detection circuit. When the infrared receiver captures the command signal from the projector, it converts the infrared optical signal into an electrical signal, amplifies it through a pre-amplifier, and processes it through the command signal detection circuit after demodulation. Various operations are then executed based on the detected command signal. To implement the remote control function, it is essential to select the appropriate method for conveying signal instructions. Depending on the remote operation method and user requirements, various characteristics of the control signals can be configured and encoded. These configurations may include combinations of voltage direction, phase relationships of the electrical signal, amplitude, frequency, pulse width, phase relationships, isometric ranges, and pulse code combinations.
This control system employs a single-chip microcontroller, which serves as the central processing unit for managing the lighting control functions. The microcontroller is programmed to interpret the incoming signals from the infrared receiver and execute corresponding commands to adjust the lighting conditions. The system architecture is designed to ensure a seamless interaction between the transmitter and receiver, allowing for real-time adjustments to the lighting environment.
The infrared transmitter is equipped with a user interface, typically consisting of buttons that represent different lighting commands. Each button press triggers the signal generating circuit to produce a specific modulated infrared signal, which is then emitted by the infrared LED. The modulation technique used may include pulse width modulation (PWM) or frequency modulation, ensuring that each command is uniquely identifiable by the receiver.
On the receiving end, the infrared receiver is designed to capture the modulated infrared signals and convert them back into electrical signals. The received signals pass through an amplification stage to enhance their strength, followed by a demodulation stage that extracts the original command signal from the modulated carrier wave. The command detection circuit interprets the demodulated signal, allowing the microcontroller to determine the intended action, such as turning the lights on or off or adjusting their brightness.
In terms of safety and efficiency, the system is designed to minimize power consumption while maintaining high performance. The use of low-power components and efficient coding practices ensures that the system operates reliably without excessive energy use. Additionally, the integration of advanced computer technology allows for future upgrades and expansions of the system, enabling the incorporation of additional features such as scheduling, remote monitoring, and integration with other smart home devices.
