Problems solved by technology

[0002] At present, the reversing radar has become the standard auxiliary system of the car, which can provide the driver with a reminder of obstacles in the rear. The reversing radar solution requires at least 4 wires for the radar probe, and the data communication adopts Local Interconnect Network (LIN) communication , therefore, the probe wire harness is more and the chip cost is higher

Abstract

The invention relates to the technical field of Internet of Vehicles, and discloses a communication interface circuit and a host. In the present invention, the communication interface circuit includes a data communication circuit, a modulation and demodulation circuit and a power supply circuit connected in sequence, and the data communication circuit is used to obtain communication data to be output, and output the communication data to the modulation and demodulation circuit. a modulation circuit, so that the modulation and demodulation circuit converts the communication data into a preset signal, and the preset signal is a signal transmitted on a power line; the power supply circuit is used to output a power signal to an external load and output the preset signal to the external load through the power line; the data communication circuit is also used to receive the feedback signal of the external load based on the preset signal, so that the communication interface circuit can provide power The data signal is transmitted at the same time as the signal to achieve the purpose of multiplexing the power signal.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, in particular to a communication interface circuit and a host. Background technique [0002] At present, the reversing radar has become the standard auxiliary system of the car, which can provide the driver with a reminder of obstacles in the rear. The reversing radar solution requires at least 4 wires for the radar probe, and the data communication adopts Local Interconnect Network (LIN) communication , therefore, the probe wire harness is more and the chip cost is higher. Contents of the invention [0003] The main purpose of the present invention is to provide a communication interface circuit and a host, aiming at reusing power lines and realizing simplification of lines. [0004] In order to achieve the above object, the present invention provides a communication interface circuit, the communication interface circuit includes a data communication circuit, a modulation and...
