A control method and device for an open Internet of Things experimental teaching platform

Abstract

The invention relates to the technical field of an embedded system and particularly relates to an open Internet-of-things experiment teaching platform control method and device. According to the method, firstly, verification based on a cloud server is carried out according to an access request of a sensor node, and access verification and safety verification of the sensor node are both realized inreal time according to the attribute information of the sensor node and matching of verification secret keys corresponding to the sensor node; secondly, an access state of the sensor node is monitored by an experiment platform in real time, whether the sensor node is in an effective control distance can be timely discovered, and control failure caused by loss of data sent by the experiment platform to the sensor node can be avoided; lastly, update of the attribute information of the sensor node is guaranteed to be more comprehensive, timely and accurate based on verification of the cloud server maintained by a developer, safety threats caused by invasion of illegal sensor nodes can be further avoided, and safety of the experiment platform is further improved. The method is advantaged in that dynamic sensor node access, withdrawal and high safety are realized.

Description

technical field [0001] The present application relates to the technical field of embedded systems, in particular to a control method and device for an open Internet of Things experimental teaching platform. Background technique [0002] With the development of the Internet and the arrival of the post-PC era, the embedded system has become an important part of computer technology, and its growing application has also made it a new research hotspot in computer information technology, showing a huge market demand. At present, many colleges and universities have set up courses related to embedded systems, so how to reasonably choose an experimental platform for system teaching, and provide colleges and universities with an embedded system with complete functions, low price, popular technology, and meeting the dual needs of teaching and development. System course teaching experiment system is an important subject to be studied and solved. [0003] In the prior art, the document ...

AI Technical Summary

Problems solved by technology

However, although the above method has experimented with connecting sensors to the Internet of Things experimental platform at any time, there are still many disadvantages. For example, first of all, in the above method, the user needs to manually set the attribute information of the sensor every time the sensor is connected. The number of sensors is large, and there is a problem of low sensor access efficiency; secondly, the above method only provides the access method of sensor nodes, and does not propose how the sensor nodes exit the Internet of Things experimental platform, which will cause the data access of sensor nodes to be too high. As a result, the Internet of Things experimental platform takes up a lot of memory, which affects the efficiency of the experimental platform for sending and receiving node data, and even causes the Internet of Things experimental platform and sensor nodes to freeze or even crash; finally, in the Internet of Things experimental platform Connecting new sensor nodes inside the network will have a certain impact on network security. The above-mentioned sensor node access method has great security risks. If criminals access the network, it may affect the Internet of Things experimental platform or even the campus network. safety

[0004] Based on the above analysis, a control method and device for an open Internet of Things experimental teaching platform with dynamic access and exit of sensor nodes and high security has not been proposed in the prior art
