Simulation of wind controller circuit.

Shown for the simulation of natural wind control circuit. The controller consists of step-down circuit, the clock signal, counting distributor, random signal, analog switches, timer selector switch, thyristor control circuit. Buck rectifier circuit which provides DC voltage for the entire controller.
A power by IC1 (555) and R4, R5, R6, C4 and other components of the beginning multivibrator oscillator, the oscillation period T=0.693 (R4 R5 2R6) C4, icons corresponding to the cycle parameters about 5 seconds. The output signal is added to the IC2 of the CP side (14 feet), as a clock signal.
IC2 (CD4017) is a decimal counting / pulse divider. When the count state, IC2 under the control of the CP, the output Q0, Q1, Q2 … … Q7, Q8 followed by high pulse occurs, the corresponding electronic switches SW1, SW2 … … SW7, SW8 opened one by one. Corresponding to the IC3, IC4 … … IC9, ICt0 output of random signal in order to increase the electronic switching audio amplifier BG1, BG2, amplified signal by the capacitor C7 added to the SCR SCR trigger side to make the SCR with the random signal The ups and downs and turn-on or semi-conducting or closed. The corresponding rate of random change motor running, air volume also changed randomly, similar to natural wind. .
Analog electronic switches SW1 ~ SW8 CD4066 by the composition of two four-way switch. Random signal source IC3 ~ IC10 audio integrated circuits using 9300 series. 9300 different pieces of memory can be regarded as random signal generator. IC13 using high-power driver switch assembly circuit Bin TWH8778, drive current up to 1A. When the timer selector switch to a different time K1 gear aside, the regular time, the CD4017 will drive the corresponding bit of the high IC13, so turn the relay pull-J2, J2-1 normally closed contacts disconnect so that loss of electricity due to the release of J1, cut off the power. K2 switch to eliminate switching to natural wind. DL transmission for the reactor, with strong, moderate, weak three-block can be used to select the strength of natural wind.
