Campus classroom test paper information processing system
Technical Field
The invention relates to the technical field of education, in particular to a campus classroom test paper information processing system.
Background
The book reader is also called cursor book reader, which is a kind of light, machine and electricity integrated computer peripheral recording equipment. The special computer input equipment can quickly identify the scribbled content on the information card and transmit the scribbled content to the computer for processing. The basic principle of the book reader is that the light emitted by the light emitting device is irradiated on the information bit of the information card, if the information bit is blackened, part of the light is absorbed, the reflected light is weakened, otherwise, the reflected light is strengthened, the corresponding receiving tube converts the light signals with different strengths into electric signals, and the recognition of the characters in the information card is completed after A/D conversion, digital filtering and mode recognition.
The existing paper reading method can only read the test paper of one plate once, the test paper is too many, the test paper among various shifts is easy to be disordered, and the manual placement is troublesome when the paper is read every time.
Disclosure of Invention

In order to achieve the purpose, the invention adopts the following technical scheme:
a campus classroom test paper information processing system comprises a base, wherein an examination paper marking mechanism is arranged on the outer wall of the top of the base, a control panel is arranged on the outer wall of one side of the base, placing mechanisms are arranged on both sides of the outer wall of the top of the base, each placing mechanism comprises a placing box, sliding rails with annular structures are fixed on the outer walls of both sides of each placing box through bolts, chain wheels are fixed on the inner walls of both sides of each placing box through bearings, the outer walls of the two chain wheels are connected with a same chain, mounting plates distributed at equal intervals are arranged on the outer walls of the chains, a speed reducing motor is fixed on the outer wall of the top of each placing box through bolts, the output shaft of the speed reducing motor is connected to the output shaft of one chain wheel, the inner walls of the two sliding rails in one placing mechanism are connected with a paper receiving mechanism in a sliding mode, and the, the mounting panel is connected with receiver and receipts roll mechanism respectively.
Preferably, receive a roll mechanism including accomodating the board, and the one side outer wall of accomodating the board is provided with the arc.
Preferably, the outer wall of one side of the containing plate is hinged with a mounting frame, and one end of the mounting frame is provided with a pressing wheel.
Preferably, both ends of the mounting rack transmission shaft are sleeved with volute springs.
Preferably, the outer wall of one side of the containing plate is provided with a pressure sensor, and the pressure sensor is connected with a controller through a signal line.
Preferably, the speed reduction motor is connected with a switch through a lead, and the switch is connected with the controller through a lead.
The invention has the beneficial effects that:
this campus classroom paper information processing system sets up through the both sides at base top outer wall and places the mechanism, accomodates the paper of waiting to read through the mechanism of receiving in placing the mechanism, drives the chain action and then drives through gear motor and receive the mechanism and remove to the realization is once placed the paper that can read a plurality of classes, has improved the efficiency of reading.

In the figure: the automatic paper feeding device comprises a base 1, a paper marking mechanism 2, a control panel 3, a storage box 4, a speed reducing motor 5, a storage mechanism 6, a sliding rail 7, a chain wheel 8, a chain 9, a mounting plate 10, a paper storage mechanism 11, a storage box 12, a storage plate 13, an arc plate 14, a pressing wheel 15, a volute spiral spring 16 and a pressure sensor 17.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-4, a campus classroom examination paper information processing system comprises a base 1, a paper marking mechanism 2 is arranged on the outer wall of the top of the base 1, a control panel 3 is arranged on the outer wall of one side of the base 1, placing mechanisms 6 are arranged on both sides of the outer wall of the top of the base 1, each placing mechanism 6 comprises a placing box 4, slide rails 7 with annular structures are fixed on the outer walls of both sides of each placing box 4 through bolts, chain wheels 8 are fixed on the inner walls of both sides of each placing box 4 through bearings, the outer walls of the two chain wheels 8 are connected with a same chain 9, mounting plates 10 distributed equidistantly are arranged on the outer walls of the chains 9, a speed reducing motor 5 is fixed on the outer wall of the top of each placing box 4 through bolts, an output shaft of the speed reducing motor 5 is connected to an output shaft of one of the chain wheels 8, a paper receiving mechanism 11 is, and another both sides inner wall sliding connection who places two slide rails 7 in the mechanism 6 has receiver 12, mounting panel 10 is connected with receiver 12 and receive a roll mechanism 11 respectively, receive a roll mechanism 11 including storage plate 13, and one side outer wall of storage plate 13 is provided with arc 14, one side outer wall of storage plate 13 articulates there is the mounting bracket, and the one end of mounting bracket is provided with pinch roller 15, scroll spring 16 has all been cup jointed at the both ends of mounting bracket transmission shaft, one side outer wall of storage plate 13 is provided with pressure sensor 17, and pressure sensor 17 is connected with the controller through the signal line, gear motor 5 is connected with the switch through the wire, and the switch is connected with the controller through the wire.
The working principle is as follows: when the examination paper marking device is used, a test paper to be marked is placed on the storage plate 13 on the paper storage mechanism 11 and is pressed through the pressing wheel 15, the paper storage mechanism 11 moves to the side of the paper marking mechanism 2 to mark the paper during marking, when one paper storage mechanism 11 marks the paper, the pressure sensor 17 on the storage plate 13 cannot detect pressure, the speed reduction motor 5 is started to drive the next paper storage mechanism 11 to move, so that the side of the paper marking mechanism 11 is caused, and continuous automatic marking is realized.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
