The on-board host is the core component of the on-board infotainment system, which can be connected and expanded with other devices through a variety of communication interfaces, among which RS232 and USB are two common communication interfaces.
RS232 interface is a serial binary data exchange interface technical standard, in daily life will often come into contact with electronic products, most electronic products will have RS232 interface, is one of the serial communication interface standards, as early as 1970 by the United States demodulator manufacturers jointly developed a unified standard for this interface. On the on-board host, the RS232 interface is often used to connect with GPS, compass and other sensor devices to obtain more accurate on-board positioning and navigation information.
USB interface is a universal serial bus interface, it can connect the mobile device with the vehicle host through the connection cable, to achieve data transmission and charging and other functions. In the car host, the USB interface can be connected with mobile phones, tablets and other mobile devices, providing mobile phone hands-free, Bluetooth connection, audio playback and other functions, but also through the USB interface to charge mobile devices.
In addition to RS232 and USB interfaces, the vehicle host may also support a variety of other communication interfaces, such as CAN bus, LIN bus, Ethernet, etc., to facilitate users to expand and connect according to actual needs. For example, CAN bus is a kind of network protocol used for the internal communication of the vehicle. It CAN connect multiple vehicle devices through CAN bus to realize information sharing and collaborative work. LIN bus is a low-cost single bus communication protocol, which can connect intelligent sensors, actuators and other devices through LIN bus to achieve intelligent control and other functions.
In short, the on-board host that supports a variety of communication interfaces can be easily connected and expanded with other devices, providing a richer on-board function and a more intelligent on-board infotainment system.
