Automotive Painting Mechanized Converyor Control System Design

Field-bus is connected intelligent field devices and automation systems all-digital, bi-directional, multi-station communication system. With a fully digital communication, openness, inter-operability and interoperability, system architecture and other technical features of a high degree of dispersion in the industrial process control systems more and more widely applied. Auto Body paint coating production line model changing, large production flexibility, on-site complex, using a distributed field-bus architecture, the control signal sent to the device as long as the annex to the control module, and then sent through the bus control center. This will enable the system constitutes a simple, easy to maintain.With the modern factory automation rising, Control systems required to achieve the various components for data exchange. PLC technology, communications technology, inverter technology, the rapid development of our modernization drive control systems to meet the complex requirements of the control system, provides a good technical foundation and theoretical basis. In this paper, the automobile coating production line as the research object in order to build coating production line automatic monitoring system as the target, the relevant control technology research, and design and development of the corresponding control systems, algorithms and software to achieve the right coating production line monitoring and control functions.First, the studies based on field bus painting production line to build automated monitoring system bus technology. The study features including field-bus, the network model, bus protocol, and several other aspects. Secondly, the design of the synchronous operation of the electric drive control system, change the original mechanical drive shaft synchronous operation control method, through the PLC as an algorithm controller, inverter-driven AC induction motor using a low-cost program. Based on the hardware program, and design constraints under the condition of the actual PID control algorithm to achieve reproduced at the synchronous operation control. Second, for how to improve the lift speed regulating device in the smooth running, safety and efficiency issues, analyze the work of the lift characteristics of the process to establish timing relationships between the various operating parameters of PID tuning parameters are, in the scene of motor performance parameters of the test results are analyzed, and hoist system, speed variable frequency vector control performance is analyzed.
