Abstract

The invention discloses a student examination paper automatic collecting device and method. The device comprises a single-chip microcomputer, photoelectric switches, a nixie tube, motors, conveying belts, iron chains, roller shutters and a control panel. The single-chip microcomputer serves as a main controller. The photoelectric switches are used for counting examination paper. The nixie tube is used for displaying the count. One of the conveying belts is used for conveying the examination paper into the device, and the other is used for operating the device from front to back or from back to front. The device is hoisted by the iron chains. The roller shutters can wind and unwind the iron chains up and down. The motors control the conveying belts and the roller shutters to operate. The control panel is used for controlling the whole device. A release button in the control panel is pressed down to put down the device from a ceiling to be placed beside students, then a start button is pressed down, the students put the examination paper into the conveying belts, the examination paper is automatically taken back into the device and counted, an invigilation teacher presses a stop button when the process is finished, the examination paper is taken out of the device, and the numbers displayed on the nixie tubes of all the devices are accumulated. The device has the advantages of being high in examination paper collecting speed and accurate in examination paper counting.

Description

technical field [0001] The invention belongs to the technical field of sending and receiving test papers, and in particular relates to a student test paper automatic winding device and method thereof.
