The utility model relates to the technical field of teaching-matched experimental (training) equipment, in particular to a model training device which is used for leading students to carry out programming exercise and obtain practical operation situations. The device comprises a machine base; a water supply tank, a drainage tank, a water supply pump, a drainage pump and a control box are mounted on the machine base; a DDC controller, a power supply and a site control system of a relay are mounted in the control box; both input and output control signals are connected with a connecting terminal of the site control system; water supply and drainage are monitored and controlled through downloading a procedure to the programmed DDC controller; a water supply tank liquid level sensor is mounted in the water supply tank; and a drainage tank liquid level sensor is mounted in the water drainage tank. The model training device has the advantages of simple structure and compact volume and is convenient for the students to carry out programming exercise and obtain real dynamic simulation during the control to reach the theory and practice combination teaching purpose, thereby arousing the interest of the students on studying control programming.
