Summary of the invention
The purpose of the utility model is through the student attendance system of a kind of combination far Distance RFID (RF identification) and human body sensing technology is provided, and solves electronic attendance mode that existing school uses and is prone to cause school gate to block up and delay, the inaccurate problem of work attendance.
For achieving the above object, the utility model adopts following technical scheme:
A kind of student attendance system that combines 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, said RFID reader is connected with the campus information terminal respectively with human body sensing device;
Further, said RFID reader comprises ultrahigh frequency RFID reader or microwave RFID reader;
Further, said human body sensing device comprises infrared inductor or ultrasonic sensing device.
Its principle of work is following:
The RFID reader reads the far Distance RFID card information, and gives the campus information terminal with this information uploading; When human body sensing device is sensed human body through induction region, produce trigger message, and give the campus information terminal this information uploading; The campus information terminal carries out logical process to the information that reports, and generates attendance record accurately.
The utility model reads the information of far Distance RFID card through the RFID reader; And the Card Reader information that the RFID reader is produced through the campus information terminal and the trigger message of human body sensing device generation carry out logical process; Realize remote work attendance and generated accurate attendance record, solved electronic attendance mode that existing school uses and be prone to cause school gate to block up and delay, the inaccurate problem of work attendance.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model content is described further.
Principle of work
As shown in Figure 1, the RFID reader reads the far Distance RFID card information, and gives the campus information terminal with this information uploading; When human body sensing device is sensed human body through induction region, produce trigger message, and give the campus information terminal this information uploading; The campus information terminal carries out logical process to the information that reports, and generates attendance record accurately.The campus information terminal is with work attendance information reporting campus information management platform server, and the campus information management platform carries out business processing to work attendance information, as: work attendance statistics, work attendance information are transmitted business such as the head of a family.
Embodiment 1
As shown in Figure 2, the student wears the radio frequency induction district that the far Distance RFID card gets into the RFID reader, and the RFID reader reads the far Distance RFID card information, and gives the campus information terminal with this information uploading; When human body sensing device is sensed the student through induction region, produce trigger message, and give the campus information terminal this information uploading; The campus information terminal carries out logical process to the information that reports, and generates attendance record accurately; The campus information terminal is with work attendance information reporting campus information management platform server, and the campus information management platform carries out business processing to work attendance information, as: work attendance statistics, work attendance information are transmitted business such as the head of a family.
The logical process mode:
1) enter the school: the campus information terminal is in the unit interval (supposing 3 minutes), and the campus information terminal is received far Distance RFID card information and induction trigger message continuously, then writes down the far Distance RFID card information, and generates the school attendance record;
2) go out the school: the campus information terminal is in the unit interval (supposing 3 minutes), and the campus information terminal is received far Distance RFID card information and induction trigger message continuously, and then the far Distance RFID card information record before the contrast if any identical, then generates the school attendance record.
Embodiment 2
As shown in Figure 3, when the student wore the far Distance RFID cartoon and crosses radio frequency induction district A (calling the A district in the following text), RFID reader A read the far Distance RFID card information and gives the campus information terminal with this information uploading; During through radio frequency induction district B (calling the B district in the following text), RFID reader B reads the far Distance RFID card information and gives the campus information terminal with this information uploading; When human body sensing device is sensed the student through induction region, produce trigger message, and give the campus information terminal this information uploading; The campus information terminal carries out logical process to the reporting information of receiving, generates attendance record accurately; The campus information terminal is with work attendance information reporting campus information management platform server, and the campus information management platform carries out business processing to work attendance information, as: work attendance statistics, work attendance information are transmitted business such as the head of a family.
The logical process mode:
1) enter the school: the campus information terminal is received the far Distance RFID card information earlier and is continued to receive the human body sensing trigger message in the A district; Afterwards; In the unit interval (supposing 2 minutes); The campus information terminal is received the far Distance RFID card information in the B district, then writes down the far Distance RFID card information, and generates the school attendance record;
2) go out the school: the campus information terminal is received the far Distance RFID card information earlier and is continued to receive the human body sensing trigger message in the B district; Afterwards; In the unit interval (supposing 2 minutes); The campus information terminal is received the far Distance RFID card information in the A district, then writes down the far Distance RFID card information, and generates the school attendance record.
Obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those skilled in the art carry out the equivalence change or change the every other embodiment that is obtained according to the utility model, all belong to the scope of the utility model protection.
