Automatic switch device

An automatic switch device, applied to a breeding house, wherein the automatic switch device comprises:

• a door frame, configured to be mounted on an edge of a passageway opening of the breeding house;
• at least one door plate, movably mounted on the door frame;
• a transmission component, mounted on the door frame and being force-transmittingly coupled to the at least one door plate;
• a drive component, mounted on the door frame and being force-transmittingly coupled to the transmission component, wherein the drive component is configured to drive the transmission component, and the transmission component is configured to drive the at least one door plate to move translationally relative to the door frame in a first direction to open or close the passageway opening;
• an in-position detector or a cut-off switch, wherein the in-position detector is provided on the door frame and configured to generate a sensing signal when the in-position detector detects that the at least one door plate is moved to a closed position relative to the door frame;
• the cut-off switch is provided on the door frame and configured to cut off a power supply circuit connected with the drive component when the at least one door plate is moved to a closed position relative to the door frame;
• and
• a main control board, wherein the main control board is connected with the in-position detector or the cut-off switch, the main control board is configured to receive the sensing signal detected by the in-position detector or receive a power cut-off signal sent by the cut-off switch, and configured to stop the drive component working according to the sensing signal or the power cut-off signal.
