Description
Technical Field
The invention relates to the technical field of Internet of things teaching, in particular to an experimental teaching method and system based on real-time construction of the Internet of things.
Background
The method is oriented to society to open high-quality experimental education resources in a remote online and virtual simulation mode, and is an important direction of education informatization in China. With the gradual landing of new concepts such as 5G, cloud computing, artificial intelligence, internet of things and the like, the manner and way of people to acquire educational resources are also changing. Under the background, how to fully play the basic role of the education resources by utilizing the information technology and expand the depth and the breadth of coverage of the high-quality education resources is an important direction of education informatization.
The traditional experiment teaching is generally developed based on entity teaching resources and a closed management system, students and instruction teachers operate the entity experiment resources in the experiment teaching process, and the traditional experiment teaching comprises links of preparing software and hardware environments, connecting equipment, safety protection, operating experiment steps, analyzing experiment results and the like, and completing experiment tasks at specified time and place. The defects of the mode include large preparation, organization and maintenance workload of the experimental environment, relatively limited time and place of student experiments, relatively difficult participation of school staff in experimental activities and relatively low utilization rate of laboratory resources. In addition, with the rise of MOOC (large-scale online open course) teaching modes, many laboratories are beginning to provide remote virtual simulation services to the public based on the internet. However, model-based software simulations sometimes do not completely replace the role of physical objects in experiments, such as device non-idealities, delay characteristics, etc. Some universities have built remote experimental systems based on campus networks and infrastructure within the universities. The system mainly aims at the experiment teaching requirements of teachers and students in schools, provides online reservation and remote control service of experiment resources, and effectively improves the resource utilization rate and service quality of laboratories. In consideration of factors such as network safety, site use and management system in a campus, the construction period of a remote experimental system based on the campus network is generally longer, the running and maintenance costs are higher, and the system is difficult to open to the whole society.

In the prior art, the experiment of the Internet of things is limited by devices, the types of direct entity attempts are very few, the experiment by inserting a sensor between each component terminal is a very difficult and complex project, if the experiment is used as an entity experiment only, the time and the labor are very consumed, and students cannot learn various combination modes and the construction of the Internet of things in the process of actually operating the experiment; then with the rise of online teaching, many courses can realize teaching by means of an interactive platform online, but experimental teaching of the Internet of things does not have such a mode; therefore, a system and a method for realizing real-time construction of experimental teaching of the Internet of things on line are needed; meanwhile, because online teaching often needs to participate in an external network, but real-time construction of the Internet of things can be influenced by fluctuation of data transmission, an internal network and an external network need to be separately constructed so as to ensure that experimental data can be modeled in time.
Referring to fig. 1, the experimental teaching method based on real-time construction of the internet of things comprises a plurality of student ends, a teacher end and a cloud server; each student end is connected with the teacher end through an intranet gateway; the teacher end is connected with the cloud server through an external network gateway; the method for implementing construction comprises the following steps:

acquiring a connection protocol of a device terminal simulation object and a sensor simulation object, wherein the connection protocol is a commonly used protocol in an Internet of things gateway, such as a protocol of TCP, UDP, coAP, lwM2M, MQTT; these protocols correspond to the application scenario of the communication, and there may be differences between the sensor and the terminal, and between the terminal and the terminal, so students are required to select appropriate protocols according to the functions that the students need to implement; after the protocol and the connection equipment are selected, generating an agent control node according to the connection link of the equipment terminal simulation object and the sensor simulation object, wherein the sensor corresponds to an environment threshold value or a temperature and humidity threshold value to be detected to respond, so that communication transmission of some columns is initiated to realize the control function of the Internet of things, and after the sensor is accessed, naturally generating the agent control node to indicate that the sensor or the terminal is actually accessed, so as to form a series of data chains which can respond; the expression form is control simulation as in EDA design software, but the terminal animation and the sensor animation are presented at the student end, and the process is a common means in the prior art and is not repeated; after the proxy control node is generated, verifying whether the connecting link is operable according to an operation command issued by a student end, and acquiring state information of the connecting link;
the state information of the connection link is uploaded to the teacher end, the connection link is mapped to the cloud server according to the state information of the connection link, and whether the connection link is successful or not is verified, because only the cloud server is connected with an external network, the computing power and the simulation capability of the connection link are very strong, the connection link established by the student end can be verified based on the existing connection and serial port form on the network, whether the connection link is successful or not is judged, and the connection link verification can be carried out in a data exhaustion mode of all proxy control nodes through the cloud server; and feeding back the result to the student end through the teacher end if the result of the connection link is successful. Through the method, a teaching process for constructing the experiment of the Internet of things on a teaching platform in real time can be established, the whole process is stable and safe to transmit, meanwhile, the experiment can be of various types, and the full utilization of calculation force is ensured; the method saves money for purchasing a large amount of entity terminals, ensures that students can self-try various combinations of the Internet of things, verifies understanding of the students, and has no danger.
In this embodiment, referring to fig. 2, when the experimental component requests to display all the equipment terminal simulation objects and the sensor simulation objects according to the internet of things; the equipment terminal simulation object also displays a first communication serial port and a first function serial port; the sensor simulation object displays a second functional serial port and a second communication serial port; acquiring a serial port type of connection protocol selection connection; and feeds back to the teacher end. The serial port function is calibrated, and the students are required to be assisted to learn the related knowledge of the Internet of things because the platform plays a main role in education.

Because the structure of the Internet of things has high requirements on the placement and assembly of hardware, teaching is performed in an online simulation mode; moreover, the function is realized by an idealized function, so that a teacher is required to add or adjust the function by the student to simulate the condition and phenomenon of mutual interference between the sensors when the sensors are simultaneously connected with the terminal, and the creativity of the student can be stimulated to solve the possible problems in practice, so that a better teaching effect is achieved.
