Based On The Lin-bus, The Intelligent Home Appliances And Communication Systems,

Modern appliance is growing very fast and becomes smarter and smarter. Touch screen,USB interface,Ethernet interface,high resolution LCD,etc. are not new to families nowadays.People's requirements are growing fast, too.One may want to control his air-condition or range remotely by his cell phone.LIN(Local Interconnect Network) used to be employed in vehicles as a low cost solution.Today,the research and application of LIN is becoming better and better in other countries,but the research in our country is still in the beginning and narrowed in auto area.It will have great benefit both in theory and reality if we design the LIN-bus application in modern smart appliance.Based on the deep research of LIN Spec 2.0,this paper will introduce the concept of LIN and how to build stable LIN interface with cheap components.We will use a smart range as an example to demonstrate how to design a cheap and high reliability LIN-bus for appliance.We will discuss the possibility of mass-production of LIN-bus in modern smart appliance by the circuit simulation,and lab debugging.Also,we will give some advice on the key parameters of the components and EMI.
