Mobile phones: Infrared technology was also used for file transfer and data exchange between early mobile phones.
Digital cameras: Some digital cameras support infrared transmission function, which can quickly transfer photos taken to computers or other devices.
Industrial automation:
Short-range data transmission: Infrared wireless communication is often used between industrial site equipment, such as communication between PLC and sensors and actuators.
Automated control: Infrared sensors can be used to detect objects, measure distances, and realize automated control.
Medical equipment:
Medical data transmission: Data transmission between medical equipment, such as the connection between an electrocardiograph and a computer.
Other fields:
Smart home: Infrared technology can be used to control devices in smart home systems.
Museum: Infrared sensors can be used to trigger explanations in museum exhibit introduction systems.
Limitations of infrared communication
Short transmission distance: Infrared rays are easily absorbed by water vapor, dust, etc. in the air, and the transmission distance is short, generally within ten meters.
Linear propagation: Infrared Canada Telegram Database propagation requires a straight path and is easily blocked by obstacles.
Susceptible to ambient light interference: Strong natural light or artificial light can interfere with infrared communication.
Technical development of infrared communication
Wavelength division multiplexing: By using infrared light of different wavelengths, multiple signals can be transmitted simultaneously on a transmission link to improve spectrum utilization.
Spread spectrum communication: By widening the bandwidth of the signal, the anti-interference ability can be improved and the bit error rate can be reduced.
Modulation technology: Using different modulation methods, such as ASK, FSK, PSK, etc., can improve the transmission rate and anti-interference ability.
