传统风扇存在的功能单一、智能化程度低等问题，为了弥补传统风扇的缺点，基于相关技术设计一款智能调温风扇是大势所趋。该系统采用了模块化设计思路，采用STC89C52单片机作为主控芯片对风扇进行控制，通过单片机与外围电路连接，实现温度、红外光电、距离等信号采集，并将采集到的数据发送至主控制器进行处理分析，实现了风扇自动开启与关闭等功能，并根据实际情况进行不同档次的运转。还增加手动控制功能，使其可在任意时间内随意打开或关闭风扇，同时也可根据需要对相关模块进行修改以满足不同用户需求。测试结果表明，该风扇控制系统能够根据环境温度和人体红外信号实现风扇的自动启停和调速，具有一定的应用价值。

With the improvement of the national economy, the number of taxis is increasing, and the meter provides a basis for the regular maintenance, maintenance and scrapping of vehicles. Aiming at the problems of lack of conditions, interference factors and low reliability, this paper develops an intelligent taxi meter by using single chip microcomputer technology, and achieves intelligent pricing function under the premise of reducing cost.This design uses STC89C52 single chip microcomputer as the main control chip to design a more intelligent taxi meter, which effectively solves the problem that night and day charges are not the same, the design has two modes, day and night, the starting price of 8 yuan during the day, more than 2.5 kilometers for 1.7 yuan/kilometer, when the customer arrives, When the driver presses pause, the fare stops, can be cleared after the customer gets off, and then restarted when the next customer gets on. At night, the starting price is 9 yuan and 1.7 yuan per kilometer after 2.5 kilometers. Through the combination of software and hardware, the design can finally solve the problem of the current taxi charging, and the taxi driver can view the current time, speed, total kilometers, unit price, total amount through the display screen, and the design stability is also strong, the cost of equipment is low, and the reliability is also strong.
