Project Background
At present, in every family, children’s affairs are the most important things, and parents are always concerned about their children, especially the children’s health, safety, education and other issues. Whether the child arrives at school on time, whether he goes home on time after school, the child’s performance at school, etc. are all concerned with the parents’ hearts. Although communication tools such as public telephones and mobile phones are very popular now, due to strict school management, students and parents cannot get in touch in time. At the same time, teachers do not have too much energy to communicate with parents on the phone one by one every day. Therefore, there is still no convenient and practical way of information communication between students, teachers and parents, which can allow parents to fully control their children and track and guide them in a timely manner.
Project Objectives
How to strengthen the information communication between Jingya Primary School and parents more easily, effectively and quickly, so that parents can timely and accurately understand the various situations of their children at school, and let the school and class teacher timely and accurately understand the students’ life and learning after returning home , has always been a problem that Jingya Primary School and families have generally paid attention to and focused on solving. Both schools and parents want to know:
1. The safety of the child (whether to attend school or leave school);
2. Children’s attendance status (whether they arrive at school on time, leave school, whether they are late, leave early, etc.);
3. The child’s school status;
In order to improve the above problems and form a situation in which the society, school and family jointly manage the safety education of students, Shenzhen Zhongke Xunlian Technology Co., Ltd. has adopted long-distance radio frequency identification system products on the basis of summarizing years of experience, and integrated the cutting-edge long-distance The organic combination of radio frequency identification technology, computer network technology, wireless communication technology and automatic control technology can record the time of students entering and leaving the school gate in real time, effectively preventing students from leaving the school at will during class, and realizing a high degree of automation and scientific management of personnel, thereby To form a bridge of communication and co-management between the school and the parents of the students.
Detailed explanation—–School Newsletter
1) Students carry a 2.4G composite electronic student ID card (hereinafter referred to as “electronic student ID card”), which works in an active mode and is powered by a built-in battery in the card. The electronic student ID card continuously and actively sends out radio frequency signals and has a long transmission distance. The radio frequency signal is coded, and the code of each electronic student ID card is unique;
2) It is necessary to install the electronic student ID card reader inside and outside the campus gate, and adjust the installation position;
3) Assign electronic student ID cards to students, and establish a one-to-one correspondence between “electronic student ID cards” and “persons”;
4) The identifier uploads the information of reading the electronic student ID card to the server through the special transmission line, and then judges the entry and exit by time;
5) Xuexintong server, which stores the basic information of students, which can be accessed by Xuexintong platform. Student information is transmitted from the server to the SMS platform;
6) Send short messages to parents through the short message platform, so that parents can understand the situation of students entering and leaving the school;
7) The system administrator can enter the relevant information of students through the school communication management system, and parents and teachers can log in to the school communication platform to communicate through the Internet.
School Newsletter Work Network Diagram
Schematic diagram of the way students enter and exit
As shown in the “schematic diagram of the way students enter and exit”, in order to judge entry and exit, the radio frequency area of the identifier inside and outside the school gate is on the only way for students to enter and exit the school gate, so that the data can be accurately received.
Students must wear a 2.4G electronic student ID card when entering and leaving the school gate, and the identifier will continuously send out card search instructions. When a student passes through the radio frequency coverage area A outside the school gate, the electronic student ID card is recognized by the recognizer. At this time, the electronic student ID card interacts with the recognizer and uploads the card number. When the student passes through the school gate and passes through the radio frequency coverage area B in the school gate, the electronic student ID card is recognized by the identifier again. At this time, the electronic student card interacts with the identifier again and uploads the card number.
The information machine summarizes all the received data and transmits it to the system server through the 3G wireless network. The server judges the students’ entry into the campus according to the time of uploading the data (card number).
The server uses the short message platform to generate a short message to send a short message to the parents of the students.
The process of leaving school is similar to the process of entering school.
Parents rest assured SMS notification (safe SMS)
Student Arrival Notification: Students enter the school gate as usual, without any operation, the system will automatically identify the student’s information, and automatically send a text message to the student’s parents to notify the parents that the child has arrived safely at school;
Student leaving school notification: Students leave the school gate as usual, without any operation, the system automatically recognizes student information and automatically sends a text message to parents to notify parents that their children have left school.
student attendance record
Students entering and leaving the school automatically record the attendance status, and generate attendance reports for the school’s statistical query.
Text messages between teachers and parents
School Notice: Teachers will send parents meeting, fee notice, notice of parents coming to school, etc. to parents;
Student situation notification: Teachers send students’ classroom performance, homework, conduct comments, test scores, recent status, etc. to parents;
Parent Message Box: Parents can send text messages to the student’s head teacher and school leaders to leave a message.
Convenience—–Campus Phone
The electronic student ID card used by students needs to be pre-installed on the campus with a card-type phone. Students only need to insert the electronic student ID card with the SIM card installed (the SIM card needs to be enabled for communication) into the card-mounted phone deployed in the campus to dial any number. telephone.
Easy school management
1) Students are only required to bring their 2.4G composite electronic student ID card to or from school every day;
2) In addition to students who need to wear electronic student ID cards, the long-distance card reading equipment installed at the school gate will completely collect students’ daily entry and exit conditions.
Easy for students to use
When students carry 2.4G composite electronic student ID cards in and out of the school gate, they can easily realize long-distance credit card attendance;
Evaluation—–safe and stable
1) The electronic student ID card reader has the characteristics of waterproof and anti-shock;
2) High anti-interference, no special requirements for the surrounding environment, strong environmental adaptability;
3) The internal circuit is highly integrated, the device failure rate is minimized, and the operation is reliable;
4) Using active identification card, no electromagnetic pollution, maintenance-free, safe to use;
5) Ultra-low power consumption, the power consumption of the electronic student ID card reader and 2.4G composite electronic student ID card is only 1 mW, which is far lower than the power consumption of any mobile phone, which is safer and healthier for the human body.
At present, the 2.4GHz multi-functional school communication system of Jingya Primary School has been installed and debugged by the mobile school communication system and put into normal operation. Some students have received 2.4G electronic student ID cards. Parents are requested to pay attention and report to the school in time if you find any problems!
