A Temperature Controlling System Of Car Seats Based On CAN Bus

In today’s society car utilization rate is higher and higher, especially the use of private cars is morepopular, so people are becoming more and more pursuit on how to improve the vehicle ride comfort.Thissystem discussed in this paper is a temperature controller on car seats.The temperature controllingsystem,which is based on CAN bus,and provides many functions,including data acquisition,data displayingand temperature controlling,for the purpose to raise the comfort of car driving.Under the study of the design of CAN bus nodes and the design of the Single-chip microcomputer,anew generation of temperature controlling system of car seats on CAN bus is developed,which takesadvantage of the technology process in the fields such as electronic sensor and controlling.The system notonly performs the general functions such as the on time detecting of seats’ temperature,but also hasfunction of temperature controlling and temperature displaying.So it makes the high level intelligence ofseats controlling come true.The system is made up of two smallest units,the one is data collecting unit,the other is temperaturecontrolling unit.The data colleting unit is to finishing the collecting s ignal of temperature,send thetemperature date to LED displayer.Then send the date to controlling unit by CAN bus and finish the holefunctions.The temperature controlling unit is to judge the open or close signals and perform A/Dfunction,and to finish the measuring of date by collecting unit,and then perform control.The main discussing of the text is the temperature controlling unit and the data collecting unit,thedesign of the hardware and soft ware of the system and anti-interference design, debugging andsimulation.Then reach the demand of system function.
