Considering strong disturbance environment in the field area, redundant design in bus cable, CAN controller and driver is involved to assure the reliability of data transmission.
考虑到现场的环境干扰较强，对总线电缆及CAN控制器、驱动器采用了冗余设计，保证数据传输的可靠性。

The stress inspection of steel cable, and the judgment and analysis of health status of steel cable is an unresolved but desiderated problem in engineering field.
Finite element method (FEM) was used to partition the area of buried cables with outer heat sources and calculate the temperature field with given cable load.
