+# Ets运行锁
+
+### 简介
+
+本示例展示了阻止系统休眠的运行锁功能，通过黑白色壁纸模拟息屏、亮屏状态，来展示系统的休眠状态，从而对运行锁的功能进行测试，使得该运行锁在打开后可以阻止系统休眠。
+
+### 使用说明
+
+1.先点击**查询支持**按钮，查询系统是否支持该锁。
+
+2.点击**定时息屏**按钮，系统在5秒后可定时灭屏（黑色背景模拟）。
+
+2.打开锁开关，系统被阻止进入休眠状态，5秒后将会一直亮屏（白色背景模拟）。
+
+3.关闭锁开关，系统被禁止休眠状态解除，5秒后将会到点灭屏（黑色背景模拟）。
+
+4.待灭屏后，点击屏幕任意一处即可亮屏（白色背景模拟）
+
+### 约束与限制
+
+本示例仅支持在标准系统上运行。
