The paper writes in detail the achievement of the research and development of a new intelligent controller with capacitance level measuring instrument. The first part of this paper introduces the present status of home and abroad development of intelligent level measuring instruments. The second part discusses the general design scheme of intelligent level controller; the control scheme of the main body with a single chip microcomputer is selected in this control system. The third part emphatically analyzes the hardware design of the intelligent controller. The last part particularly introduces the software design of this intelligent controller, in which a modularized programming method is adopted. The remarkable characteristics of design in this controller are the use of a great deal of peripheral chips, which arc in serial connection with the SCM. They greatly simplify the circuit and the structure of the system hardware, thus achieving a high-level system integration.
