Improve Production Efficiency

During the hydrometallurgical production process, there are many towers working at the same time. In order to improve production efficiency, we need to control the level height of every tower. Takes example for 6 towers, do research on the level control system in metal ions production process. According to the theory of materials balance, the mathematic model of the system are established. Programmed the mathematic model by Matlab. In order to make the level of each tower at the same height, work out how many adjust times needed and how much adsorbate every tower inflow and outflow each time. Then analysis the data results of error and variance, which have confirmed the feasibility and rationality of the level automatic balance system model established in this paper.

Smart Flush is an innovative product in mechanical engineering. All the skilled workers need to      improve the quality of product that would be manufacture. The three objectives of this study are as  follows: (i) to design automatic water level control based on electrical conductivity of the water; (ii) to improve the supply of water into the water tank as well as avoiding any accessing water; and (iii) to provide easy installation and maintenance. 5W + 1H concept are used to solve the problem. The     existing water level for toilet flushing system employs mechanical method, which is commonly expose to mechanical failure. This research introduces the notion of water level controlling within the context of electrical conductivity of the water. System design integrates the electrical and electronic based   water level sensing and couple with solenoids shut off valve in a wired environment. The system equipment is lower power consumption, equipment only work when the water level changes, usually is in a waiting state. Smart Flush approach would help in reducing water overflow and low water pressure in the piping system. Maintaining water level inside the toilet pump system is an essential aspect in order to avoid waste of water due to overflow.

In this paper, a liquid level control system was designed and fabricated. Control of the liquid level was accomplished by adjusting the sup-ply voltage to a centrifugal pump that is delivering the liquid from a reservoir tank to an upper tank. The liquid level control system was implemented on an ATmega328 microcontroller. Three control strategies are implemented, manual mode, ON/OFF controller, and PID controller. Serial communication is used to establish the communication between the ATmega328 and a computer running MATLAB soft-ware. A graphical user interface was constructed to allow users to interact with the system. The system model is obtained using an experi-mental approach. The obtained model is then used for the design of the PID controller. Experimental results are provided to highlight the performance of the implemented controllers.
