The model selection analysis is made on the air brakes for 160 km/h rapid freight cars from such aspects as the operation mode, main control mechanism, materials of key parts and working type.

Design of the active ball handling mechanism of RoboCup MSL robot

This paper introduces the mechanism of the electro-hydraulic control system of the hydraulic support on comprehensive mechanized mining face, probes into the main functions of both subordinate controller and principle controller and the design of CAN node.

This paper introduces the work principle and characteristic of electric hydraulic control system of hydraulic powered support in coal mining face with coal plough,and the hardware structure and function of the principle controller and subordinate controller,the communication of system which is by CAN bus.

Designs the powered supports microcomputer distributed control system and describes the functions of principal controller and subordinate controller,and the working principle of double communication nets and control method.

This paper describes the work principle and function of the powered supports controlled by single-chip-microcomputer distributed control system, presents an solution of the hardware design of principal controller and subordinate controller, the communication between the principal controller and subordinate controller and the communication of master computer and slave computer is based on VC6.
