Control the design of automatic transformation of ten wind speed

RF cable can be customized for other specifications

As shown in the figure, the control circuit for automatically changing the 10-speed wind speed is shown. The circuit includes a clock signal generator signal generator IC1 and a counter counter. The clock signal generator is a multivibrator oscillator composed of IC1 (555), R2, R3, W1, W2, C3, etc., the signal frequency depends on the charging and discharging time constant, and can be changed by adjusting W1, W2. The frequency of the signal and the duty cycle duty cycle. The low-frequency square wave generated by IC1 is used as the count pulse of IC2 and added to the CP terminal (14-pin). The corresponding decimal counter counter counter is an electronic counter with multiple measurement functions and multiple uses. It can measure frequency, period, time interval, frequency ratio, accumulate count, timing, etc.; with the corresponding plug-in, it can also measure phase, voltage and so on. Generally, we classify all counters with both frequency measurement and measurement week as general purpose counters.
The A, B, C, and D4 binary codes generated by IC2 (C192) are added to the decimal decoder IC3 (CD4028). With the addition of CP, the translated BCD codes are in turn at the output terminals Q0, Q1...Q8, Q9. High level, which provides the basis for automatic transformation for wind speed shifting.
The synchronous phase shifting circuit can change the signal outputted by the IC3 sequentially, thereby changing the thyristor. The thyristor is a high-power semiconductor device of a P1N1P2N2 four-layer three-terminal device made of silicon crystal, generally composed of two thyristors. Connected in reverse. Its function is not only rectification, but also can be used as a non-contact switch to quickly turn on or off the circuit, to convert the direct current into an alternating current, to convert one frequency of alternating current into another frequency of alternating current and so on. Like other semiconductor devices, thyristors have the advantages of small size, high efficiency, good stability, and reliable operation. Its emergence has made semiconductor technology enter the field of strong electricity from the field of weak electricity, and has become a component used in industry, agriculture, transportation, military research, commercial and civil appliances.
The conduction angle of the SCR makes the motor motor of the motor an electromagnetic device that utilizes the law of electromagnetic induction to convert or transfer electrical energy. It relies on rotation to generate drive torque for use as a power source for electrical appliances and various machinery. The terminal voltage changes in order to achieve automatic conversion of the 10 wind speed.
