Description

Based on network check class attendance system

Technical field

The utility model relates to the school classroom electronic attendance system, specifically refers to a kind of single-chip microcomputer wireless receiving and dispatching that utilizes, the system that complete that the student registers, demographics and network data transmits.

Background technology

Society is an information society, and network is universal is informationalized product.Save the energy and resource, progressively realize that with no paper office is conservation-minded society's trend of the times.The method that the work attendance of most school student adopts is mainly following several, the one, and upper class hour teacher calls the roll, and number of student is more now, and teacher's point once name generally will spend 5 to 10 minutes, affects Students ' Learning, also affects teacher's teaching process.The 2nd, Student Cadre is checked the number of people, and has a strong impact on like this study of Student Cadre, because Student Cadre dare not report strictly according to the facts, makes work attendance inaccurate again.The 3rd, teaching management Departmental organization personnel check number clearly to each bancor duty, and this has spent a large amount of manpower and materials, also cannot be sustained.So some electronic attendance systems or device arise at the historic moment, the retrieval Chinese patent literature, the patent No. 201120420832.0 discloses a kind of Student Attendance System in conjunction with far Distance RFID and human body sensing technology, comprise far Distance RFID card, campus information terminal and campus information management platform server, it is characterized in that, also comprise at least one RFID reader and at least one human body sensing device, described RFID reader is connected with the campus information terminal respectively with human body sensing device; The utility model reads the information of far Distance RFID card by the RFID reader, and the trigger message of the Card Reader information RFID reader produced by the campus information terminal and human body sensing device generation carries out logical process, realize remote work attendance and generated accurate attendance record, having solved electronic attendance mode that existing school uses and easily caused school gate to block up and delay, the inaccurate problem of work attendance.This attendance checking system weak point is that far Distance RFID card and RFID reader and campus information terminal must be arranged.Everyone must be with the RFID identification card student.China Patent No. 201120052772.1 student's electronic attendance and notifying devices, comprise high-frequency radio frequency card, the first card reader, the second card reader, data processing unit and the SMS transmission module of working in coordination, note receiving trap, this high-frequency radio frequency card and the first card reader, the second card reader are suitable, the first card reader and the second card reader are located on student's passage, the distance of the two is greater than the twice of described high-frequency radio frequency card operating distance, and this first card reader, the second card reader and SMS transmission module all are connected with data processing unit.The school gate student that the utility model can be avoided causing because swiping the card blocks up and trapping phenomena and student forget the situation of swiping the card, can avoid because student's school gate that repeatedly shuttles at short notice causes the note situation that even equipment is made mistakes that takes place frequently simultaneously, and help with teacher and find that in time the student asks someone on behalf of the situation of swiping the card.Above-mentioned attendance checking system respectively has advantage, but wide popularization and application is subject to various factor restrictions that certain difficulty is arranged.Student's electronic attendance and notifying device also must everyone be with the RFID identification card, and the RFID identification card very easily loses, and a people also can be with many cards, separately set up the campus information terminal and everyone RFID relative cost is also high.

Summary of the invention

The purpose of this utility model is to provide a kind of based on network check class attendance system with low cost.

The technical solution of the utility model is: based on network check class attendance system directly is connected and forms main circuit with single-chip microcomputer with the USB interface communication module by keyboard input, digital demonstration, wireless receiving; Hardware main circuit is assembled in a capsule, and keyboard input, the digital demonstration are contained in the capsule side; Infrared counting forms classroom demographics hardware auxiliary circuit to pipe and wireless transmit; Utilize wireless receiving and dispatching to communicate by letter with main circuit, single-chip microcomputer and USB interface transfer data to host computer and realize network service.

The capsule that hardware main circuit is housed is placed on dais; The hardware auxiliary circuit that infrared counting forms pipe and wireless transmit integrated package, the frequency adjustment difference is divided into A, B, is arranged on respectively the both sides on doorway, classroom.

Wireless receiving integrated circuit CSJR02A receives the radio signal on the door of classroom, and the number of student statistics is completed by single-chip microcomputer P15,16,17 peripheral key circuits, to the class number, by 74HC164 and three LED, is shown; Single-chip microcomputer 89C51 and PC special communication USB interface integrated circuit adopt USBN9602.

The utility model is compared with other electronic attendance systems, has without identification card: avoiding the student to forget swiping the card, lose card etc. can't work attendance.Error correcting capability is strong: other people number as defeated as student generation, can cause statistical number of person not right.Timeliness is strong: the student Enters Number and enters classroom and can obtain checking-in result immediately.Sharing is high: Adoption Network communication, each classroom checking-in result can be shared by each teaching management department, has reduced various forms, has saved a large amount of paper.Movability is good: native system can carry out separately work attendance, also can insert any computer and form network attendance.This check class attendance thought of design is novel, simple in structure and low in cost, and the raising managerial personnel of efficiency and teacher's work attendance efficiency the check class attendance system is worked to class, to(for) the supervision student have actual meaning.
