在日常使用电脑的过程中,我们经常会遇到需要定时关机的场景,比如:
虽然 Windows 自带 shutdown 命令可以定时关机,但操作方式较为繁琐,缺乏可视化界面。因此,本篇文章将带大家实现一个基于 PyQt5 的 Windows 定时关机工具,支持定时或延时关机、重启、注销,并提供系统托盘功能,方便随时管理关机任务。
本工具主要具备以下功能:
定时关机 —— 设定具体时间,到点自动关机。
延时关机 —— 设置倒计时,倒计时结束后自动关机。
重启 & 注销 —— 除关机外,还可执行系统重启和注销操作。
取消操作 —— 关机前可随时取消,避免误操作。
系统托盘支持 —— 运行后最小化到系统托盘,不影响日常操作。
人性化提示 —— 关机前弹出提醒,避免突发关机。
在运行代码之前,我们需要先安装 PyQt5 库:
1 |
pip install PyQt5 pyqt5-tools |
以下是完整的代码实现:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 |
import sys import os import time from PyQt5.QtWidgets import QApplication, QWidget, QLabel, QPushButton, QVBoxLayout, QTimeEdit, QSystemTrayIcon, QMenu, QAction from PyQt5.QtGui import QIcon from PyQt5.QtCore import QTimer, QTime
class ShutdownApp(QWidget): def __init__(self): super().__init__() self.initUI()
def initUI(self): self.setWindowTitle('Windows 定时关机工具') self.setGeometry(600, 300, 300, 200)
self.label = QLabel('请选择关机时间:', self) self.timeEdit = QTimeEdit(self) self.timeEdit.setDisplayFormat("HH:mm")
self.startButton = QPushButton('设置关机', self) self.startButton.clicked.connect(self.scheduleShutdown)
self.cancelButton = QPushButton('取消关机', self) self.cancelButton.clicked.connect(self.cancelShutdown)
layout = QVBoxLayout() layout.addWidget(self.label) layout.addWidget(self.timeEdit) layout.addWidget(self.startButton) layout.addWidget(self.cancelButton)
self.setLayout(layout)
# 托盘功能 self.trayIcon = QSystemTrayIcon(QIcon("icon.png"), self) trayMenu = QMenu() exitAction = QAction("退出", self) exitAction.triggered.connect(self.close) trayMenu.addAction(exitAction) self.trayIcon.setContextMenu(trayMenu) self.trayIcon.show()
def scheduleShutdown(self): shutdown_time = self.timeEdit.time() current_time = QTime.currentTime() seconds = current_time.secsTo(shutdown_time)
if seconds <= 0: self.label.setText("请选择一个未来的时间!") return
self.label.setText(f"关机已设置,将在 {shutdown_time.toString()} 执行") os.system(f'shutdown -s -t {seconds}')
def cancelShutdown(self): os.system('shutdown -a') self.label.setText("关机已取消!")
if __name__ == '__main__': app = QApplication(sys.argv) ex = ShutdownApp() ex.show() sys.exit(app.exec_()) |
1 |
python shutdown_tool.py |
1 |
shutdown -a |
Windows 提供 shutdown 命令来执行关机任务:
1 |
shutdown -s -t 秒数 |
1 |
shutdown -a |
我们使用 QTime 计算当前时间到设定时间的 秒数,避免时间计算错误:
1 |
seconds = current_time.secsTo(shutdown_time) |
使用 QSystemTrayIcon 实现最小化到托盘:
1 |
self.trayIcon = QSystemTrayIcon(QIcon("icon.png"), self) |
这样即使窗口关闭,应用仍能在后台运行。

界面简洁,操作方便
系统托盘支持,后台静默运行
支持定时 & 倒计时模式,满足不同需求
支持多任务管理(同时设置多个定时任务)
增加日志记录(记录每次关机任务)
增加任务进度条(倒计时可视化显示)
如果你对这个工具感兴趣,可以尝试优化它,让它变得更加智能!

我们使用 QTime 计算当前时间到设定时间的 秒数,避免时间计算错误:

self.trayIcon = QSystemTrayIcon(QIcon("icon.png"), self) |
这样即使窗口关闭,应用仍能在后台运行。

界面简洁,操作方便
系统托盘支持,后台静默运行
支持定时 & 倒计时模式,满足不同需求
支持多任务管理(同时设置多个定时任务)
增加日志记录(记录每次关机任务)
增加任务进度条(倒计时可视化显示)
如果你对这个工具感兴趣,可以尝试优化它,让它变得更加智能!
