Embodiment
A kind of Intelligent electric power regulator, is characterized in that comprising controllable silicon, zero cross detection circuit, short-circuit protection circuit, current detection circuit, controller, sample circuit, compensation amplifying circuit, intelligent instrument, host computer, temperature sampling circuit and resistance furnace; Wherein zero cross detection circuit, sample circuit are all connected with controller with controllable silicon; Current detection circuit is connected with controllable silicon by short-circuit protection circuit; Resistance furnace is connected with temperature sampling circuit; Temperature sampling circuit is connected with host computer; Host computer is connected with controller by serial line interface; Resistance furnace is connected with intelligent instrument; Intelligent instrument is connected with sample circuit by compensating amplifying circuit.
A kind of Intelligent electric power regulator of the present invention, described controller adopts single-chip microcomputer 89C4051 chip.Described controllable silicon comprises ac thyristor, drives controllable silicon and light activated power thyristor.Described sample circuit is that digital-to-analogue adopts circuit.Described digital-to-analogue sample circuit adopts ADC0832 chip.Described controller is made up of processor, expanded circuit and reset circuit, and hardware reset circuit is made up of MAX813 chip and peripheral circuit element.MAX813 has the several functions such as system reset, " house dog " timing output, supply voltage detection, and reset pulse is the positive pulse of 200 ms.Containing the built-in twitter circuit that disappears of electrification reset in circuit, during M---R-step-down, RESET pin is by the positive pulse of generation 200 ms, the input WDI pin that if microcomputer does not trigger at the appointed time " house dog ", and WDI pin is not in vacant state, " house dog " timer WDO will become low level, make M---R-pin become low level.During system worked well, often send a signal by P2.1 to WDI at regular intervals, make MAX813 internal counter restart counting.During CPU cisco unity malfunction, can not accomplish normal " feeding dog ", MAX813 internal counter will soon overflow, and makes RESET terminal potential step-down, forces the RESET of CPU end to become low level, makes system reset.Control system hardware circuit is made up of terminal address circuit, zero passage detection, the detection of intelligent instrument temperature signal, host computer temperature sampling, thyristor gating circuit, serial communication circuit and overload protecting circuit etc.With 89C4051 single-chip microcomputer for core, after single-chip microcomputer powers on, terminal address is read to internal storage location; Data acquisition delivers to A/D conversion by intelligent instrument 4 ~ 20 mA current signal after compensating and amplifying, nickelchromium-nickelsiliconthermocouple delivers to host computer after temperature sampling; Power Regulation part is heated by light activated power thyristor, driving controllable silicon and two-way exchange SCR control resistance furnace.Intelligent controller both can be used as an independently single-chip computer control system, can coordinate again and form two stage control system, have higher dirigibility and reliability with microcomputer.The main body of controller is single-chip microcomputer, and it and some expanded circuits form processor module.The intelligent instrument output signal of measuring tempeature is generally 4 ~ 20 mA electric currents, and this signal single-chip microcomputer can not directly process, and must carry out pre-service.First current signal is sent into analog to digital conversion circuit after discharge circuit amplifies and send into single-chip microcomputer again, by according to this digital quantity, single-chip microcomputer judges that the interval residing for temperature then takes appropriate measures.Simulating signal, after sample-hold circuit, obtains the sample pulse of continuous analog signal, and they are continuous analog signal instantaneous values on given time, are not digital signal.Also each sample pulse to be converted to the digital quantity be directly proportional to its amplitude., computing machine control, microelectric technique, Power Electronic Technique are combined, achieve networking and intellectuality that electric power controls, meet the requirement of clustered control under mass production environment.
