The design of a scanning magnet power-supply used in a 10MeV industrial radiation accelerator is presented in this paper. The consideration of linear magnetic field current and the principle of triangle wave modulator are included. In addition, the control system based on single chip and its anti-jamming scheme in industrial circumstance are also introduced. The scanning magnet power-supply can produce continuous triangle waveform current. The frequency can be adjusted by step length of 1Hz ranged from 20Hz to 50Hz, and the peak-to-peak current is 20A.

Emergency Power

According to the special requirements of power supply for seismic station, a new single-phase emergency power supply control system is proposed in this paper. The principle and structure diagram of the system is illustrated. The control strategies of the system and hardware design of key circuits are discussed in detail. The emergency power supply control system adopts high-property C8051F310 single chip micro-computer. According to the monitoring value of input voltage, the system switches between charging and inverting. Main circuit of inverting uses single-phase full-bridge topology. To correct a power factor, charging system applies boost circuit to make input current follow to a given current reference. Experiments validate the feasibility of the proposed design.

In order to solve the problem of cleaning small and micro pipelines, the control system of the cleaning robot for small and micro pipelines is designed using single-chip technology. Draw the circuit design flow chart, use PROTEUS software to design the display and control circuit of the DC adjustable regulated power supply, stepping motor. Write and debug the program that controls the start and stop of the motor, accelerate and decelerate, and rotate forward and reverse in keil4; import the program into the single-chip microcomputer, and use the PROTEUS software for simulation and simulation. The experimental results show that the designed control system can realize the two actions of the pipeline robot going straight in the pipeline and the cleaning head rotating.

The power supply for the superconducting outsert of Steady High Magnetic Field Facility (SHMFF) in High Magnetic Field Laboratory of Chinese Academy of Sciences requires very high precision and high stability (10 ppm of 13kA). In this paper, a multiple controller has been developed which is in combination with analogue control in the voltage-loop and digital control (RST algorithm) in the current-loop. The system model and the detailed design and evaluation of the method are all presented. And the simulation and experimental results finally manifests that the output current can follow the reference perfectly (no lagging error, no overshoot), and its precision (<10ppm) and the output voltage fluctuation (<1%) both meet the requirements. Therefore, the proposed control system for the superconducting power supply is proved to be feasible.

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.
