The Tire Pressure Monitoring System Design Of Off-road Vehicle

This paper puts forward a kind of suitable for off-road vehicle tire pressure monitoring system design.Paper in the light of the features of the off-road vehicle,the three mainstream of tire pressure monitoring schemes are analyzed and select the most appropriate single direct tire pressure monitoring.Combined with a certain suv models,this topic defines its function and performance requirements of tire pressure monitoring system,as well as project implementation route and scheme.Papers on the design of sensor and the receiver respectively are discussed.Sensor design including sensor selection and the internal working model.The working mode can be for the power consumption under the condition of keeping the sensor battery use time to cover the vehicle warranty period.Receiver scheme including the design of the circuit principle diagram of the receiver and the receiver antenna system.The change value of antenna design can guarantee the monocoque body case of shielding to strengthen the interference of signal transmission will not affect the normal communication.Internal working mode and receiver antenna sensor restructuring is the original design scheme.Due to the selection of the sensor sends the data format of data format and the networking requires a different,must increase in receiver signal conversion,this scheme also defines the message format and the signal classification.Paper vehicle carring and integration solutions are discussed in detail,including the receiver optimization layout position and sensor rim restructuring.After the completion of the design,through the bus system completed the function verification of vehicle,and pick up the vehicle after vehicle system functional testing,strict comprehensive functional verification and vehicle system test,validate the tire pressure system of the matching degree of the suv system.
