Wi-Fi智能定时器的设计

The Design Of Wi-Fi intelligent timer

介绍了由脉冲发生电路、逻辑控制电路、数码管显示电路和继电器控制电路结合完成了一种实用Wi-Fi智能定时器的设计。主要实现三大功能:通过按键对Wi-Fi进行定时、显示定时时间和定时关闭Wi-Fi。首先通过脉冲发生电路产生秒脉冲,再经过3600分频电路输入到逻辑控制电路中,在逻辑控制电路中通过按键对Wi-Fi的使用时间进行定时,同时计时时间通过七段数码管显示,由继电器控制电路控制Wi-Fi的开与关,当定时时间到达后,继电器断开,Wi-Fi关闭。

Describes the design and implementation of the wi-fi intelligent timer based on the combination of pulse generator circuit, logic control circuit, digital tube display circuit and relay control circuit. The three main functions： the wi-fi timing, display timing and shut down ofwi-fi by pressing the key. First, the pulse generating circuit generates a second pulse, and then through the 3600 frequency division circuit input to the logic control circuit, the use time of wi-fi in the logic control circuit timing, and the timing time through seven segments of digital tube display, the relay control circuit controls the opening and closing ofwi-fi, when the timing arrival, the relay disconnect, wi-fi to shut down.
