Description

Remote wireless real-time online programming download control system based on Internet and RFID

technical field

The invention relates to the technical field of Internet education programming, in particular to a remote wireless real-time online programming download control system based on the Internet and RFID.

Background technique

In recent years, the government and society have gradually paid more attention to programming education. Children's programming in my country may be undergoing a transformation from "non-needed" to "imposed". It can be seen from this that its development prospects are very promising, so we further analyzed the current pain points in the industry, mainly including the following four aspects:

Pain point 1: The existing children's programming education model has drawbacks

At present, programming education for young children adopts an online teaching mode. From the initial one-on-one teaching, it has gradually become a small class live teaching. Teenagers watch live broadcasts or video tutorials on their mobile phones or computers at home. Problems that arise cannot be solved in time. Online teaching cannot guarantee whether young people are learning programming, the learning effect is not good, and it cannot correctly guide young people to learn programming.

Pain point 2: It is difficult to choose a programming language for teaching

Courses offered by mainstream training institutions include scratch, C and C++, and python. Scratch is an introductory course for almost all programming classes for teenagers. Scratch is not a language. In the software, children can use a method similar to building block stacking to realize fast programming of codes, which does not involve coding. Graphical programming is not real programming, but training the logical thinking of programming, just like the addition, subtraction, multiplication and division of mathematics, it is very basic. Learning algorithm programming requires a certain foundation in English, so designing transitional courses suitable for children across the country is the key to the development of children's programming in China. The C language, C++ and python are the most helpful for young children. The Information Olympiad for primary and secondary school students examines the C++ language. C++ adds new features on the basis of the C language and can easily achieve visual programming. Learning C++ directly will be very difficult, especially for teenagers, it is easy to lose their interest in programming. C language is relatively simple. Learning C language is equivalent to learning half of C++. When switching from C language to C++, there is no need to start from scratch. However, because C language is difficult to achieve visual programming, it needs to be combined with hardware to arouse learning interest and achieve better training results. Because it is linked to hardware, it requires a higher level of teachers, and this kind of teachers is not very good. Mining, so most training institutions do not choose to use it.

Pain point 3: The existing children's programming software and hardware are seriously decoupled, and children know what is happening, but not why

Existing children's programming software is almost independent of hardware. Children don't know anything about hardware components during the learning process, and they don't know why robots have human-like senses, language, and actions. Growth, innovation and creativity to increase and improve the functions of robots, there is a big missing in innovation education.

Pain point 4: The existing online and offline programming for children cannot be effectively combined

Existing children's programming training courses are either online or offline. For example, the famous offline programming training "Lego Robot Programming" has high hardware costs and offline training costs, which are difficult for ordinary families to afford. After the offline training courses are over, children cannot carry out online programming and experiments according to their interests. The effect is limited. For online programming, such as "Coding Cat", children can only learn programming in front of the computer, and the results of programming can only be displayed on the computer. This kind of programming learning greatly reduces children's interest in programming learning. If there is a platform for programming learning, children can not only learn programming, but also play for children, which can greatly improve the teaching effect of programming.

To achieve the combination of children's programming software and hardware and the combination of online and offline, it is necessary to have a remote wireless real-time online programming download control system.

Referring to the Chinese patent application publication number CN107703818A, a wireless programming maker education intelligent controller based on WiFi transmits the graphical programming module and user information of the upper computer running on the remote terminal to the server, and then the server graphically After the programming module is compiled, it is downloaded to its intelligent controller through the WiFi wireless router. This method has the following disadvantages: (1) The program is not directly controlled on the end user's computer for online compilation and download, but is transmitted to the server, which compiles and downloads. The time is prolonged, and the user cannot get timely feedback and experience program compilation in real time. and download process. (2) According to the technology provided by this patent, the server can only compile the graphical programming module of one programming terminal at a time, and can only download the program for one intelligent controller at the same time. If there are multiple programming terminal users Simultaneous operation, the delay for queuing compilation and downloading will be longer.
