| As we all know, in cold winter, especially in north area, the temperature of outdoor is 10 Celsius scales under zero even reach dozens Celsius scale under zero. However many people's car will place out of the door just because they have no carport. To startup the cars in this temperature is not only difficult but also harmful to the car and shorten the life of the car.This item come from Canada llyco automotive provides warm system. The aim of this thesis mainly is to design the telecontrol equipment, which includes a remote control and a receiver. C50 model remote control is a wireless RF launch controller of 600 meters effective distance, which has the LCD and the keyboard interface. The receiver receives the command of remote control and then send the command to ECU (electronic control unit). ECU control mechanical device heat up the engine and the cab under control strategy. And receiver simultaneously launch the room temperature of cab to remote control. In this paper, it includes the wireless RF communication of 600 meters effective range and the RS-232 wire serial communication of 2 to 10 meters range. |
