Abstract

The invention relates to a small card pulling-out prompting system in a campus water room and a using method thereof. The system comprises a voice singlechip main board, a light emitting diode (LED) indicating lamp, a slot-type photoelectric switch and a hall flow sensor, wherein the singlechip main board is sealed in a metal box; the LED indicating lamp is arranged on the metal box and connected to the singlechip main board through a lead; the slot-type photoelectric switch is arranged at the position of an original campus card insertion position and is connected with the singlechip main board through a signal transmission line; and the hall flow sensor is connected in series with a water outlet part of a water tap in the water room and connected with the singlechip main board through a signal transmission line. Due to detection of the slot-type photoelectric switch and the hall flow sensor and the control of the singlechip main board, a student who forgets to pull the card out can hear a voice and receive a prompt from the LED indicating lamp; and such an event that students often forget to pull the cards out can be avoided effectively. The card pulling-out prompting system is lower in cost and convenient to install and can be widely applied to various water supply systems in the campus water rooms.
