Brief description of the drawings
Fig. 1 is the structural schematic block diagram of Intelligent electric power regulator of the present invention.
Embodiment
A kind of Intelligent electric power regulator, as shown in Figure 1 including controllable silicon, zero cross detection circuit, short-circuit protection circuit, electric current
Detect circuit, controller, sample circuit, compensation amplifying circuit, intelligence instrument, host computer, temperature sampling circuit and resistance furnace；Its
Middle zero cross detection circuit, sample circuit and controllable silicon are connected with controller；Current detection circuit passes through short-circuit protection circuit
It is connected with controllable silicon；Resistance furnace is connected with temperature sampling circuit；Temperature sampling circuit is connected with host computer；Host computer leads to
Serial line interface is crossed with controller to be connected；Resistance furnace is connected with intelligence instrument；Intelligence instrument is by compensating amplifying circuit with adopting
Sample circuit is connected.
A kind of Intelligent electric power regulator of the present invention, the controller use single-chip microcomputer 89C4051 chips.It is described can
Controlling silicon includes ac thyristor, driving controllable silicon and light activated power thyristor.The sample circuit is that digital-to-analogue uses circuit.The digital-to-analogue
Sample circuit uses ADC0832 chips.The controller is made up of processor, expanded circuit and reset circuit, hardware reset electricity
It route MAX813 chips and peripheral circuit element is formed.MAX813 has system reset, " house dog " timing output, power supply electricity
The multiple functions such as pressure detection, reset pulse are 200 ms positive pulse.Contain the twitter circuit that disappears built in electrification reset in circuit,
During M---R- step-downs, RESET pins will produce 200 ms positive pulse, if microcomputer is not triggered and " seen at the appointed time
The input WDI pins of door dog ", and WDI pins are not at vacant state, and " house dog " timer WDO will be changed into low level, make
Obtain M---R- pins and be changed into low level.It is every to send a signal to WDI by P2.1 at regular intervals during system worked well,
So that MAX813 internal counters restart to count.During CPU cisco unity malfunctions, it is impossible to accomplish normal " feeding dog ",
MAX813 internal counters will soon overflow so that RESET terminal potential step-downs, force CPU RESET ends to become low electricity
It is flat so that system reset.Control system hardware circuit by terminal address circuit, zero passage detection, intelligence instrument temperature signal detection,
Host computer temperature sampling, thyristor gating circuit, serial communication circuit and overload protecting circuit etc. form.With 89C4051 monolithics
Machine is core, reads terminal address to internal storage location after electricity on single-chip microcomputer；Data acquisition is believed by the mA electric currents of intelligence instrument 4 ~ 20
A/D conversions are delivered to after number compensated amplification, nickelchromium-nickelsiliconthermocouple delivers to host computer after temperature sampling；Power Regulation part is by light
