A 受管设备 is a device with AnyDesk installed that can be accessed through 无人值守访问.
That means no one needs to accept the Session on the remote side; you connect using the configured password instead.
安装了 AnyDesk 的设备，可以通过无人值守访问远程访问，这意味着没有人需要接受远程端的连接。只需密码即可连接。
该功能允许连接到远程设备，而无需另一端手动批准，只需使用密码即可访问。
A session is a screen of a device shared within a concurrent connection. You can create a connection with a remote device, and you can create another session with the same remote device. Each opened window on the connected remote device will be displayed as a separate session. In AnyDesk, session is represented in separate windows on Windows and in tabs on Mac.
