Design of Liquid Level Control System for Double capacity

Abstract :In this paper, the use of Beijing Asia control Techonlogy Limited Liability Company Kingview 6.52 version of the configuration of the screen design, which added PID algorithm tuning, so that the dual capacity of the tank level to achieve value control. The host computer software configuration, animation connection, and then with the experimental device on the dual capacity of the water tank to connect, through the serial port connection between the host computer and the next computer data communication between. At the same time can provide liquid level alarm and real-time curve and historical curve of the record. This paper is pided into five parts on the dual capacity of the tank level control system software and hardware to make a detailed discussion of two aspects. The first part of the research on the purpose and significance of tank water level control system, the development history, the present situation and the future development trend of the domestic and foreign.the second part summarizes the

composition of the whole system and the required algorithm to introduce the system to the initial structure of the program integration; the next part of the third part of the system modeling and PID parameters will be outlined; and then the forth part will be introduced The kingview of

6.52 version of the software and double tank water tank level control system for the screen design and operation; the last part of the system will be the host computer and dual-capacity water tank connection debugging, experimental collection of experimental results. To carry out the analysis, and finally to double the capacity of the tank level control system to complete.

KeyWords:Double capacity water tank; configuration king 6.52; PID algorithm; liquid level control
