Design of PLC control system for cascading tanks controlling

The article deals with the design of a PLC control system for controlling cascade tanks in the technological process of liquid mixing. The mixing process is carried out automatically according to information from individual sensors. The system also includes elements for manual control of the technological system. A human machine interface system was designed to operate the system. The simulation showed the correctness of the designed system.

PLC Control System Design for PVC Floor Detecting and Conveying Device

Traditional PVC floor detecting is done by workers’ handwork, which is hard and inefficient. So studying and designing a set of control system which is based on PLC for PVC floor detecting conveyor device. The PVC floor detecting conveyor device consists of loading, conveying and unloading and other parts. To make the whole system works in a coordinate and controllable status. Firstly, by using double layer hydraulic scissors lift to realize the lifting and stratified translational control of lifting platform; secondly, with the use of photoelectric switches, counters and other components, station transport algorithm helps the process of PVC floor detecting conveyor; Finally, according cutting control requirements of stacker, the PLC auto-control and speed optimization can be done by layered multiple stacking. Thus automated loading, conveying and unloading process are come true, greatly reducing the labor intensity and improving production efficiency.

The Research of Wire Grinding Machine and Wire Stripping Machine Control System Based On PLC

This paper introduces PLC control technology and discusses its characteristics with relay control circuit, computer, SCM control technology then it talks about the PLC control system design methods. To use the method in reality, the paper introduces wire grinding machine and wire stripping machine. In the wire grinding machine, the module is single and easier, with principle of how it works, PLC obtains the status of sensors, data such as the diameter value to control the operation of the corresponding parts to form a closed loop between PLC control system, the motor and wire diameter grinding detectors to grind the wire into segments with different diameters. Finally, the paper completes the PLC-based control system design of stripping machine. The system requires nine different ways to meet the processing requirements, the papers designs multifunctional modules to realize the requirements. Both of the two PLC systems operates very well in reality.
