The invention discloses a connection detection circuit, an alarm device and a base station. The connection detection device comprises a first connection port, a detection module, a signal processing module and an alarm module which are connected in sequence, the first connection port is used for connecting a first voltage reference plane, and the detection module comprises a first detection part, a second detection part and a detection output end. The first detection part is connected in series between the first connection port and the detection output end, and the second detection part is connected in series between the detection output end and the second reference voltage plane; the detection output end can output a first detection signal related to the potential difference between the first voltage reference plane and the second voltage reference plane, and the signal processing module can generate a second detection signal changing along with the first detection signal; and the alarm module can accurately
