According to the command of the command response unit, if the data is received, the data is decoded, stored in the logic memory unit and waits to be sent to the application system. If the data is written outwards, the data needs to be encoded and transmitted through an antenna.
The invention discloses a method for supervising campus safety by using a campus safety supervision system based on an RFID (radio frequency identification) technology, which is characterized by comprising a method for recording the attendance of students by using the campus safety and supervision system based on the RFID technology and a method for checking the attendance of the students by taking the attendance of the students by using the campus safety and supervision system based on the RFID technology.
The method for recording the attendance of the students based on the RFID technology campus security and supervision system is characterized by being implemented according to the following steps as shown in FIG. 3:
step 1, use A i Indicating the ith reader, S i Indicates the ith student label information (i)>= 0), n represents the total number of students;
when the student enters the school door, S 1 S 2 S 3 ...S n Two readers A with information arranged by school entrance 1 And A 2 Reading and storing in a database D;
and 5, judging to record the student arrival information if the student arrival information is recorded, and executing the step 2 until all information is judged.
The method for checking the student on behalf of the student by using the campus security and supervision system based on the RFID technology is implemented according to the following steps as shown in FIG. 4,
step 1, with S i Tag information indicating the ith student,
indicating the information recording time of the ith student,
indicating to record the signal strength information received by the reader of the ith student information;
the reader in the classroom will acquire S 1 S 2 S 3 ...S n Transmitting the arrival record information to a database, wherein the record information is adjacently stored in the database table;
and step 6, judging that the test attendance phenomenon does not exist, and enabling the students to normally arrive at the school.
In the system of the invention, two readers are arranged at the school gate simultaneously, as shown in fig. 5, when a student enters the school gate, the two readers are arranged at the school gate in tandem as shown in fig. 2, and because a new problem caused by the collision of the readers is avoided, the reading ranges of the two readers cannot collide, at least once the information of the student is read, but if a manager inquires through the system that the student does not record the information of the student at the school once, the manager needs to contact the student and parents of the student to know the specific conditions of the student,
the system adopts the passive electronic tag, when the tag enters a working area of the system, the antenna receives electromagnetic waves to be determined, the coil generates induced current, the induced current is rectified and combined to charge the capacitor, and the voltage of the capacitor can be used as working voltage after being stabilized. The reader-writer obtains information and then transmits the received data to the management platform through the gateway and the central switch, the management platform carries out necessary processing on the acquired information, the result needs to be displayed to a user and the request of the inside of the system or an operator needs to be processed, and the currently received information needs to be manually processed.
The invention aims to provide a campus safety and supervision system based on an RFID technology, which can prevent unsafe accidents of students in the process of going to a school and timely get in contact with parents of the students. Secondly, the mastering of the student arrival situation and the teacher attendance situation is a double supervision for the safety situation of the students in the school and is also helpful for enhancing the education level of the school. Finally, the distribution situation of the student's break-time in the school can be roughly known, the student can be found through fuzzy positioning within the readable range of the reader, fighting in the school can be prevented in time, the situation of the student in the school can be tracked, and the situation of the student's whole activity in the school can be known.
In the invention, the identification distance is 1-10m, although the data transmission distance of the passive electronic tag is shorter than that of the active electronic tag. However, in this system, too large signal transmission distance is not required, and in this system, tag information needs to be read and written every day, and a large amount of data storage is also required. Through the whole analysis and research, compared with an active electronic tag, the passive electronic tag has the advantages of low power consumption, no need of providing energy, small volume, easy use and low price. For low-frequency and high-frequency tags, the ultrahigh-frequency tags have large storage data volume, high transmission speed and long signal transmission distance. Special packaging of the label appearance is also required, so the smaller the label volume the better. Through analysis and comparison, the radio frequency identification technology in the system selects an ultrahigh frequency passive RFID system with the working frequency of 860MHz-960MHz for research.
In the invention, when a primary and middle school student enters a school gate, in order to prevent the missing of the student information, the later period needs special personnel for processing, the hardware is improved, at least two RFID readers are arranged at the school gate for recording the student information, and the student information can be recorded at least once. To prevent the occurrence of the alternative attendance phenomenon, the strength of the signals received by the reader at substantially the same point in time may be compared. The school condition of students can be tracked in the whole day according to the time sequence.
