1. 看到网上有人做硬件显示的COM口。作为资深软件开发人员，觉得这点小事情，还要掏Money来实现，有点太LOW了。 2. 直接用Python代码实现，放在启动里面，插入或者移除USB的串口，都能够正确提示。 3. 闲话少说，直接上代码。 import sys,os from PyQt5.QtWidgets import QApplication, QSystemTrayIcon, QMenu, QAction, QMessageBox from PyQt5.QtGui import QIcon from PyQt5.QtCore import QThread, pyqtSignal from PyQt5.QtCore import QTimer import serial.tools.list_ports class USBMonitorThread(QThread): device_connected = pyqtSignal(str) device_disconnected = pyqtSignal(str) def run(self): prev_ports = set(serial.tools.list_ports.comports()) while True: current_ports = set(serial.tools.list_ports.comports()) new_ports = current_ports - prev_ports removed_ports = prev_ports - current_ports for port in new_ports: self.device_connected.emit(port.device) for port in removed_ports: self.device_disconnected.emit(port.device) prev_ports = current_ports self.msleep(1000) # 每秒检查一次 class SystemTrayIcon(QSystemTrayIcon): def __init__(self, icon, parent=None): super(SystemTrayIcon, self).__init__(icon, parent) self.setToolTip("USB Monitor") self.create_menu() self.USB_thread = USBMonitorThread() self.USB_thread.device_connected.connect(self.show_connected_notification) self.USB_thread.device_disconnected.connect(self.show_disconnected_notification) self.USB_thread.start() def create_menu(self): menu = QMenu() exitAction = QAction("退出", self) exitAction.triggered.connect(sys.exit) menu.addAction(exitAction) self.setContextMenu(menu) def show_connected_notification(self, port_name): message = f"新USB设备已连接: {port_name}" self.show_notification_message(message) def show_disconnected_notification(self, port_name): message = f"USB设备已移除: {port_name}" self.show_notification_message(message) def show_notification_message(self, message, timeout=5000): # 假设5秒后关闭 msg_box = QMessageBox(QMessageBox.Information, "USB设备通知", message) timer = QTimer() timer.singleShot(timeout, msg_box.close) # 在timeout毫秒后关闭消息框 msg_box.exec_() if __name__ == '__main__': app = QApplication(sys.argv) #icon=QIcon(3GP.ico)# 替换为你的ICO文件路径 tray_icon = SystemTrayIcon(QIcon('app3_icon.ico')) tray_icon.show() while True: #添加无限循环app.exec_()\n#技术交流#
