Design Of The Economy Energy Device Controller Of Bus

Aiming at the bus in city often applying the brake and starting up ,this thesis brings forward viewpoint which is on equipping the economy energy equipment of bus .this thesis narrates work principle of this economy energy equipment.This task designs the hardware circuit of the controller of the economy energy equipment .this hardware circuit is composed of the modules which are data gather module , data traffic module , control module .The software of the controller of economy energy equipment is made up of the program of SCM , application of PC , device driver of USB . The program of SCM constitutes of ISR and main procedure. The ISR gathers data semaphore and receive correspondence data , the main procedure sends correspondence data and control the economy energy equipment of bus . the application of PC carries out serial communication , USB communication and data processing . the device driver of USB is developed by using DrvierStuio . this device driver can come true the interrupt data transfer of endpoint 1 and the bulk data transfer of endpoint 2 .the whole controller function is as follows :gathering the data of the pressure of compressor , the speed of bus , the location of brake paddle and the location of accelerator pedal . controlling the motion of electromagnetism valve and the motion of electromagnetism clutch .
