    Abstract: A monitoring device (100), a monitoring system (200) and a method for acquiring a state parameter. The monitoring device (100) includes: a sensor interface (101), a controller (102), a switch element (103) and a monitoring element (104); the sensor interface (101) is electrically connected to the monitoring element (104) and the switch element (103), and the sensor interface (101) is configured to be accessed by a sensor (203); the controller (102) is connected to the sensor interface (101) via the monitoring element (104) and the switch element (103) that are connected in parallel; the monitoring element (104) is configured to, when the sensor interface (101) is monitored to be accessed by a sensor (203), transmit a monitoring information to the controller (102); and the controller (102) is configured to, control an on-off state of a switch in the switch element (103), to select the specified sensor (203) to be powered.
