Universal Serial Bus (USB) is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices.
USB was designed to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports, as well as separate power chargers for portable devices.
In the industrial context, "USB" (Universal Serial Bus) is a standard for connecting devices to a computer or other electronic device. Here are a few examples of how USB is used in industry:
-
Data transfer: USB is commonly used to transfer data between devices, such as transferring files from a computer to a USB flash drive. In industrial settings, USB can be used to transfer data from sensors, meters, or other electronic devices to a computer or network.
-
Power supply: USB can also be used to provide power to devices, such as charging a mobile phone or powering a small LED light. In industrial applications, USB can be used to power sensors or other low-power devices.
-
Human-machine interface: USB can be used to connect input devices like keyboards and mice to computers or industrial control systems. It can also be used to connect touchscreens or other input devices to industrial machinery.
Similar technologies to USB that are used in industry might include:
- Ethernet: Ethernet is another standard for connecting devices to a network. Ethernet is typically faster than USB and can be used for more demanding applications like streaming video or controlling industrial equipment.
- Serial communication: Serial communication is a general term for the transfer of data one bit at a time over a communication channel. Serial communication can be used in a wide range of applications, from simple data transfer to complex industrial control systems.
- CAN bus: The CAN bus (Controller Area Network) is a communication protocol used in industrial control systems, especially in the automotive industry. CAN bus allows different devices to communicate with each other over a single connection.
