Description

Student attendance system {System for alerting commute school}

The present invention relates to a student arrival and departure system, which informs parents of students' arrival and departure in real time and at the same time informs students of their health status at the time of arrival and departure from school.

In the case of elementary schools, parents' interest in and participation in school life of students is growing day by day, such as having meal facilities and parents taking turns in charge of school meals. In the case of couples, indifference and conflicts between parents and children are intensifying despite the need for more attention to students.

In this situation, children are not able to overcome many temptations such as PC cafes on their way to and from school, so they hang out with their friends and engage in deviant behavior. Therefore, at the school level, great efforts are being made to eradicate deviant behavior among teenagers, but despite these efforts, the social problems of teenagers do not decrease and the age group that engages in deviant behavior is getting lower and lower.

In order to solve these problems, mutual cooperation between schools and parents is needed above all else, and a channel for communication between schools and parents is needed. Fortunately, in the case of Korea, mobile communications such as the Internet and mobile phones are developed, and it is not an exaggeration to say that the country is unmatched in wireless communications as described above.

In particular, what parents are most concerned about in relation to students' deviant behavior is whether their children went straight to school, academy, or home without falling into another way on their way to and from school, and this would be their top priority. Moreover, in the case of the lower grades of elementary school, kidnapping is common, so parents' concerns are getting serious day by day.

However, despite the development of computers, mobile communications, and wired/wireless communications in Korea, there is no systematic contact system between parents and schools, and student attendance and absence management is still conducted only on paper. As described above, if student attendance is managed only on paper, the homeroom teacher can see the attendance book and check attendance, but this is after the students have already committed deviant behavior, and parents have been contacted for a long time. get drunk later

Therefore, it is urgent to systematically manage students through the Internet, wired/wireless communication, and mobile phones, and there is an urgent need for a means capable of informing parents of students' school attendance information in real time.

In addition to this attendance management, in the event of a group epidemic such as the recent corona, there is a need to further check and confirm the health status of students performing their studies. In general, since students concentrate on their studies or activities with friends, they may not be aware of their symptoms unless major symptoms are manifested, or even if they are aware of them, they may be overlooked.

At this time, if the student's health condition is detected and checked at an early stage and treated, it will be able to greatly contribute to the prevention and initial treatment of infectious diseases of students contagious to school.

A technical problem of the present invention is to provide a means of notifying parents of school arrivals or departures of students in real time.

Optical images, thermal images, and infrared images captured by the school-to-school camera unit and the school-to-school camera unit are acquired, and through this, a specific region of the captured thermal image and infrared image corresponds to the optical image of the corresponding student. Includes an image processing unit for extracting the body temperature of the corresponding student,
When the tag information read during the school hours is not read within the school hours, the school arrival and departure notification message transmission unit notifies the student's parent's smart phone having the unread tag information that there is a problem with the student's dismissal. A message inquiring whether the student is dismissed from school is sent to the teacher's smart phone of the student whose Tag information read within the dismissal time is not read within the dismissal time, and the teacher's smart phone sends a message asking if the student is dismissed from school. notify you of a problem,
The school arrival and departure notification message transmission unit includes the school attendance video captured at the moment the student's tag information is read during school attendance, the shooting time, and the student's body temperature information in the school attendance notification message, and the parent's smartphone of the student whose tag information has been read. The dismissal video recorded at the moment the student's tag information is read at dismissal time, the shooting time, and the student's body temperature information are included in the dismissal notification message and sent to the smartphone of the student's parents whose tag information has been read. ,
The teacher's smart phone transmits the homework or report card assigned to the student to the student attendance notification server. The homework or report card assigned to the student is superimposed on the dismissal video and transmitted to the student's parent's smartphone as a single image, and the report card is superimposed on the dismissal video to transmit a single image. When a report card confirmation message is received from the smartphone, the teacher's smartphone is notified that the report card has been confirmed by the parent,
The image processing unit includes a memory storing preset matching information to spatially match the photographed optical image, thermal image, and infrared image, and when body temperature information is obtained, the thermal image pixel and the infrared image Obtained using a mapping table that shows the mapping relationship between pixel values and actual body temperature, and is continuously corrected according to the temperature measurement result from the thermal image and infrared image and the body temperature actually measured through the actual thermometer to measure more precise body temperature and set the average value of the values measured by the thermal imaging camera and the infrared camera as the final body temperature value, but if one of the thermal imaging camera and the infrared camera does not recognize the temperature as an error, an error occurs. A student attendance system characterized in that the temperature value of the egg camera is excluded and the temperature value is measured, and when the temperature is measured based on the thermal imaging camera and the infrared camera, the temperature is measured within a range of body temperature that a person can have.
According to claim 1,
The tag information is unique identification information, and may store user identification information (User_UID) information and emergency contact information in addition to Chip Unique Identifier (Chip_UID), and uses NFC (Near Field Communication) communication method, but in some cases A student attendance system characterized in that it can communicate using another wireless communication method such as Bluetooth, Zigbee, and Wi-Fi.
