The invention relates to a 51-single-
chip-
microcomputer-based speech temperature dual-
control system for a ventilation
system. The speech temperature dual-
control system comprises a
wireless transmitting host and a
wireless receiving host. The
wireless receiving host is used for receiving a
control signal transmitted by the wireless transmitting host and controlling work of a motor of a ventilation
system based on the
control signal. The wireless transmitting host includes a single-
chip microcomputer unit, a key, a speed identification module, a temperature sensor, a
liquid crystal display unit, a
wireless transmitter circuit, an LED indicator lamp, and a transmitting terminal power supply circuit connected with a power input terminal of the single-
chip microcomputer unit, wherein the key, the speed identification module, and the temperature sensor are connected with a
signal input terminal of the single-chip microcomputer unit and the
liquid crystal display unit, the
wireless transmitter circuit, and the LED indicator lamp are connected with a
signal output terminal of the single-chip microcomputer unit. The wireless receiving host consists of a wireless transmitting-receiving circuit and a
motor speed regulation circuit, wherein the two parts are connected; the wireless transmitting-receiving circuit is used for receiving a
signal transmitted by the wireless transmitting circuit; and a power input terminal of the
motor speed regulation circuit is connected with a receiving terminal power circuit and an output of the
motor speed regulation circuit is connected with the ventilating
system motor. Therefore, convenience of the operation can be improved substantially.
