Communication circuit, control method thereof and equipment with communication function

Abstract

The invention discloses a communication circuit, a control method thereof and equipment with a communication function. The communication circuit comprises a main control chip, wherein the main control chip comprises a first data port for sending data; a first expansion circuit, wherein the first expansion circuit comprises a second data port and a plurality of third data ports, and the second data port is connected with the first data port through a bus; a plurality of communication modules, wherein each communication module comprises a fourth data port and a fifth data port, the fourth dataport of each communication module is connected with each third data port in a one-to-one correspondence manner, and the fifth data port is used for being connected with a lower computer communicatingwith the main control chip. Thus, the first data port can be expanded into a plurality of third data ports, namely, one bus is expanded into multiple paths, and each path can be connected with a communication module communicating with a lower computer, so that physical isolation of each path of communication module is realized, and the situation of communication disorder is avoided.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication circuit, a control method thereof, and a device with a communication function. Background technique [0002] With the rapid development of the Internet of Things and electronic technology, communication technology has become more and more widely used in life and production. At present, communication technology has become the pulse of devices with communication functions. [0003] Taking the air conditioner as an example, the main control chip of an air conditioning unit is used as the upper computer, which can control the lower computers such as the electronic expansion valve, and can also control the lower computers such as other external air conditioning units. In order to realize the control of the lower computers by the main control chip, the main control The chip needs to communicate with each lower computer to realize data transmission. ...
