System application background
With the development of society, people’s work is getting busier and busier, while caring for their children is becoming more and more inadequate. In the case that children cannot be transported to and from school, the safety and punctuality of children going to and from school affects the hearts of every student’s parents. If students can report that they are safe when they arrive at school, and they will also inform the parents of leaving school, it will undoubtedly make parents avoid a problem. Worrying all day is also helpful for parents to understand the exact time when their children arrive and leave school, and how to conveniently and regularly understand their children’s learning and living conditions at school has become an urgent need for every parent. At the same time as a modern school, student management and the school’s own informatization development level have also become an important factor in measuring the overall development level of a school, and it is a reflection of the school’s image. Aiming at the current universal application of mobile phones (or PHS) and SMS in the masses and the characteristics of mobile phone (or PHS) SMS, Chuangsiyuan launched the “Home-School Communication” solution, the core concept of which is “advanced technology, mature Application, build a bridge for school parents to communicate”. Compared with similar products, the company’s “Home-School Communication” products have a series of unparalleled advantages. Chuangsiyuan hopes to make contributions to further promote the development of education in my country through its unique product structure, functions and services.
Basic plan
The basic operating principle of this system is roughly that each student only needs to have an RFID or wireless sensor identification card. After reaching the school gate, the sensor near the school gate will read the label and send the information to the calculator. Send a text message to the cell phone of the relevant student’s parents, such as “Dad, I have arrived at school safely”, “Dad, I will go home soon after school”, and the computer will also save all students’ entry and exit information, and Organize it into a report for schools and parents to inquire. Schools can use this platform to post school-related matters or other information on the website, eliminating various communication barriers caused by teachers’ one-by-one notifications or parents’ absence from parent meetings, which is convenient and quick. This similar system has been widely used in developed countries such as the United States and Europe, and has become a bridge between teachers and parents and is very popular.
The system also has the following advantages:
1. Automatic, long-distance (5 meters) and large flow (identify more than 200 students at the same time) automatic identification without manual swiping.
2. Automated, real-time, simple and easy communication method
3. Low cost and maintenance-free
4. Scalability: The use of this SMS platform and sensor identification can regularly communicate with parents the management information of the school and the learning situation of the students in the future.
This solution is the perfect combination of RFID identification technology and mobile phone text messaging technology.
Students enter and exit the school gate as usual, without any operations (no need to swipe their card to check attendance, do not need to do any stay, and even sit in the school bus to directly enter the school gate) The system will automatically identify student information (name, class, student ID, etc.) ), it will automatically recognize whether it is arriving or leaving school, and automatically send a text message to the parents of the students to inform them that the children have safely arrived or left school. This is the brand new experience brought by the long-distance card reader to the “Home-School Communication-Safe SMS” system.
During the peak period of school and school, the number of students is very large. If you want to use ordinary IC cards or induction ID cards to trigger the SMS system for attendance, the efficiency is very low. The school gate needs to install a large number of IC machines. However, the efficiency is still very low. There will be a long line at the school gate, and the order at the school gate becomes very chaotic. At the peak of school and after school, students even have to line up for 20 minutes in order to check in. In this way, “Home-School Link” will not only bring convenience to the school and parents, but will make the students very disgusted and change the management efficiency of the school. Low, school order is disrupted.
What is the most critical factor of “long-distance wireless attendance”? Is the reliability of the entire system operation! The premise of reliability is that the reader must not miss the card. For the school gate, where the flow of people is very large, the requirements for the data collection part, that is, the card reader, are very high. Once the card is missed, the student’s parents will not receive the safe SMS sent by the system. “The system becomes a “Worry SMS” system.
As an important part of the “Safe SMS-Home-School Communication” system, the reliability of the front-end data collection part (RFID radio frequency reader and sensor card worn by students) is the premise of the reliability of the entire system. In order for the system to operate reliably under the harsh conditions where the flow of people is concentrated at the school gate, the card reader must have outstanding anti-collision performance (read multiple electronic cards at the same time and process them in real time) Long-distance radio frequency identification equipment of Chuangsiyuan Company Using the most advanced microwave chip technology today, the performance of RFID has been substantially improved compared to the original microwave technology, and it has completely solved the identification and data of long-distance, large-flow, ultra-low power consumption, and high-speed moving markers. The transmission problem also solves the fatal weakness of low-frequency electromagnetic wave technology with short sensing distance and poor anti-collision ability (200 students per second can be identified). Its technical indicators are in the industry leading position among similar products, creating a “long-distance A new era of recognition technology. Adopting the RFID@家校通 system of Chuangsiyuan Company, completely eliminates the phenomenon of missing card reading.
Chuangsiyuan’s RFID@家校通 program uses the latest fifth-generation RFID long-distance reader and long-distance electronic tags. The fifth-generation RFID long-distance readers and long-distance electronic tags are the crystallization of Chuangsiyuan’s years of research on radio frequency solutions. Its excellent performance and high reliability ensure the reliable implementation of the entire “Home-School Communication” project.
Technology Introduction
RFID identification technology
RFID identification technology has been a cutting-edge technology for a long time, but there are few products that can meet this application and are expensive. With the opening of the microwave ISM band and the maturity of the technology, you can choose to have an effective identification distance of 2-5 meters and a flow of 200 units/ RFID identification products with a speed of 200 kilometers per second, and the cost is within the acceptable range, have considerable advantages in related application fields. We have combined the actual application of this project and used this technology. Dozens of improvements have been made to make it safer, more reliable, and more suitable for localized applications.
SMS technology
With the rapid development of communication technology and the application market, the development and operation of mobile phone text messaging technology is low in cost, safe and reliable, and the popularity of mobile phones is already very high, so the strong connection with telecommunications ensures the smooth implementation of this system .
Mode of operation
The student safety SMS system provides a value-added service. It is not only a commercial application but also a very social application. Achieving this kind of service requires the cooperation of three parties. One is a value-added service provider, which can also be regarded as a system investor or operator; the other is an equipment provider, responsible for the provision, installation and maintenance of the system’s equipment; (the two parties can also be one party Acting) The third is the school, which plays the role of consulting and intermediary in the operation. In actual operation, the school can experience the convenience that modern technology brings to the school and parents without any capital investment, and improve the school’s modernization, education quality and management level and even achieve partial profits. For system integrators and operators, the entire investment can be recovered in the first year, and then substantial value-added returns can be obtained. This is a sustainable investment strategy.
