The application of PLC in electric control system of transmission belt machine is presented in the paper.

Relates to the reason of service life of transmission belt and the factor that affects the life, andprovided the related solving methods eg.

The non-linear dynamic stability and chaotic motion of viscoelastic transmission belt with time-dependent velocities and subjected to a transverse distributed varying external excitation is investigated.

The Design of Intelligent Dectection System on Conveyor s Mechanical Failure;

At the aspect of vision track, this paper studies global nearest neighbor algorithm and multi-hypothesis tracking algorithm, implements the GNN algorithm and kalman filter in the c++ programming language and finally achieves the target track on conveyor.

In view of shortcoming of the control method which the conveyor is widely applied in the logistics conveyer and assembly Line and so on system of such fields as the machinery,light industry,wharf,chemical industry cannot information and network,the conveyor equipment is taken as an example,the network solution is summarized which the use advanced Profinet technology construction conveyor controls.

The basic structure for belt-conveyor system,the functions of the parts of the system and the system of PID control algorithm,and the algorithm for the successful implementation of the conveyor belt are introduced.

Two approaches of resolving the problem of conveyor belt, the traditional method using the theorem of momentum for system, and the method using the work-energy theorem for system, are compared.

Application of Belt Conveyor Teaching Experiment System Based on PLC;

According to the working requirement of the conveying belt on assembly line, a controllable stageless variator was designed, and its suitable parameters were selected.
