The invention relates to a buried switch machine control system for a tramcar. The buried switch machine control system for the tramcar comprises a control host, a relay, an I/O (Input/Output) board card and a switch machine. The control host is used for receiving a control command of an operation terminal; the I/O board card is used for collecting state information; and the control host is used for performing logical judging processing according to collected information. When a point section is not occupied, the position of the switch machine is inconsistent with the position where the switch machine is to be rotated, a control handle is not available for the switch machine, the point section is not blocked and a point is not singly locked, the I/O board card outputs corresponding control information and drives the relay to rotate the switch machine to a corresponding position; and after the I/O board card collects information that the switch machine has been rotated to the corresponding position, the control host stops driving the corresponding relay and disconnects a driving power supply of the switch machine. According to the buried switch machine control system for the tramcar, provided by the invention, logic processing of the control host of the switch machine and a relay interface control circuit are combined so that the buried switch machine is preferably controlled and safe, reliable and efficient operation of the system is ensured.
