Frequency-modulating electrical control system with reminding protection function

Abstract

The invention discloses a frequency-modulating electrical control system with a reminding protection function. The frequency-modulating electrical control system comprises a front-end processing circuit, a driving circuit, a fine adjustment circuit and a warning circuit, wherein the driving circuit is connected with the output end of the front-end processing circuit, and the warning circuit is connected with the fine adjustment circuit. The frequency-modulating electrical control system is characterized in that a frequency-modulating circuit is further arranged among the driving circuit, the fine adjustment circuit and the warning circuit. The frequency-modulating circuit is composed of a processing chip K1, a resistor R6, a capacitor C4, a capacitor C5 and a capacitor C6, wherein one end of the resistor R6 is connected with a DRC base pin of the processing chip K1, and the other end of the resistor R6 is connected with the driving circuit; the positive electrode of the capacitor C4 is connected with a CII base pin of the processing chip K1, and the negative electrode of the capacitor C4 is connected with the driving circuit after passing through a potentiometer R7; the positive electrode of the capacitor C5 is connected with a TC base pin of the processing chip K1, and the negative electrode of the capacitor C5 is connected with the negative electrode of the capacitor C4; the positive electrode of the capacitor C6 is connected with an SWE base pin of the processing chip K1, and the negative electrode of the capacitor C6 is connected with the negative electrode of the capacitor C4 after passing through a resistor R8. According to the frequency-modulating electrical control system, due to the fact that the frequency-modulating circuit is arranged, the frequency modulation function of the system is achieved, and the system can meet the requirement for different frequencies of the electricity load.
