A new type of intelligent hanger was designed based on single chip and Pro-E software. 3D entity model of actuator and cover curtain mechanism are established by Pro-E. Wings structure of hanger mechanical part was adopted screw rod and motor combination of the lifting mechanism can make the wings outspread and fold, unique cover curtain structure was adopted. Cover curtain rolls up and down through the motor driving. The control system adopts AT89C52 single chip. According to the information that coming from the rain sensor and the temperature sensor, two stepper motor’s positive and negative rotational motion was controlled. So as to realize automatic adjustment when it rains.

Water Meter

The control system of a new type of intelligent household water meter which can prevent water leakage is designed in this paper. That water drives the rotor-wing rotating can make micro direct-current generator generate and store power used for the system power supply. OMRON EE-SX671 type photoelectric sensor to detect water flow is used in the system. And a new water electromagnetic valve is designed, the type of which is normally open and direct-operated. If closed, it will be self-locking state and not need power supply. But it needs be reset manually. The design program based on AT89C52 single-chip microcomputer not only displays water flow using LED but also controls the automatic shut-off function of electromagnetic valve.

We preliminarily designed a power tracking and control system using single-chip computers and industrial control computer in the electric heating simulated power loop. The system is an innovational design based on the proven simulated nuclear power loop, with increased techniques of step-less power regulation system and modeling nuclear feedback effect correctional programs. We promoted both hardware and software designs of this power tracking and control system in this paper. It used single-chip computers as the core control chips and an industrial control computer as the additional correctional program and record carrier. The process and implementation of the control software are presented, which is designed as a fuzzy theoretical nonlinear system. In order to ensure the subsequent updates, the access interface of the system is open for following correctional programs, including the correctional program of void fraction effect, temperature effect, hysteresis effect and heat power distribution effect. Taken hysteresis effect correctional program as an example, we use an offset tic-tac clock replacing the inherent tic-tac clock in different devices of the system in order to reduce the hysteresis effect of measuring and corresponding errors. We also put out a preliminary analysis of the accurate synchronization for the system at the end of the paper.
