51-single-chip-microcomputer-based speech temperature dual-control system for ventilation system

Abstract

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.

Description

technical field [0001] The invention relates to a control system for a ventilation system. In particular, it relates to a voice temperature dual control system based on 51 single-chip microcomputer for ventilation system. Background technique [0002] Generally, adjusting the indoor ventilation environment often requires manual adjustment. The staff need to manually adjust the wind speed and start and stop of the ventilation system according to the temperature requirements. This requires the staff to increase their working hours. It will increase the operating cost of the enterprise. At the same time, when manually adjusting the ventilation system, there are often problems such as cumbersome operation, long operation distance, and single operation mode, and the traditional ventilation control system often uses wired control, which also causes unsightly appearance to a certain extent. Contents of the invention [0003] The technical problem to be solved by the present inv...
