[Abstract]:With the development of electronic technology and chip manufacturing technology, the electronic processor has the characteristics of high speed, micro volume, micro power consumption and so on. So it embeds the electronic processor into the home appliance and endows the home appliance "brain" with the combination of various kinds of advanced sensors. According to the change of environment, it can make corresponding adjustment on its own without human intervention, so as to improve the living comfort of users significantly. The "smart home", a new technology of convenience and security, emerges as the times require. Focusing on the convenience and intelligence brought by smart home to daily life, the paper redesigns the electric fan that we usually use. The 89C52 single chip microcomputer is used as the main controller, and the DS18B20 temperature sensor is used to measure the ambient temperature. The fuzzy PID speed regulation technology combined with fuzzy control and PID control is studied and applied to the system. It is realized that the fan can automatically adjust the fan speed with high precision by changing the ambient temperature. You can also adjust the speed of the function according to the temperature set by the user. At the same time, the design adds 1602 LCD module, HC-SR501 infrared pyroelectric sensor, ISD4004 voice module, DS1302 real-time clock chip and PT2262/PT2272 wireless remote control module, which can be automatically started when there is someone in front of the fan in the range of 100 擄. It can display the current temperature and time in real time, and users can control the fan by wireless remote control and record audio messages through ISD voice module. It is proved by test that the multi-function automatic temperature regulating fan system based on single chip microcomputer can adjust fan speed independently and accurately by fuzzy PID speed regulation algorithm in the range of 25 鈩
