Education and practical training integrated platform device based on the internet of things

Abstract

The invention relates to an education and practical training integrated platform device based on the internet of things. The platform device comprises a cabinet, and a center control computer, wireless sensor network nodes and an industrial control analog device are arranged on the cabinet; the center control computer comprises a controller, an operating screen and a communication transmission module, wherein the controller is connected with a computer, and design for a graphical programming module and a program command generation module is performed by the computer and downloaded to the controller; and the wireless sensor network nodes are connected with the controller through a Zigbee communication module in a wireless mode, and the controller is connected with the industrial control analog device through a bus. Due to the technical scheme, the controller automatic control application which is same as the automatic control application of the computer is achieved, the real-time monitoring on data acquisition of the wireless sensor network nodes and the control mechanism of the industrial control analog device are achieved through the graphical programming module and the program command generation module, students can combine key techniques of each node conveniently, application fields of the internet of things are simulated, good teaching effect is maintained, and education overlapping investment and resource waste are reduced.

Description

technical field [0001] The invention relates to an education training platform device, in particular to an education training comprehensive platform device based on the Internet of Things. Background technique [0002] As an emerging industry, the Internet of Things currently has no relevant industry application standards; at the same time, in terms of education, there is no unified specification and standard for the construction of Internet of Things laboratories in schools of various disciplines, which is in a state of disorder. Although there are many companies or schools in the market that have made many plans for the construction of IoT laboratories, most of them are for the purpose of selling products, without considering the teaching environment, and are not very close to teaching. All in all, after the construction of most laboratories, they are in an embarrassing situation such as not being used or rarely used, and students are not interested. [0003] In the proce...

AI Technical Summary

Problems solved by technology

[0004] ① The user (school) invests a lot of money: in the teaching process, it will need to install a variety of application equipment, and the teaching is limited; at the same time, a large amount of money is invested, which brings a lot of expenses to the school. Teaching is difficult to achieve comprehensive

[0005] ② Poor expandability: Application equipment including network, display equipment, and transmission ports need to be installed separately, which brings inconvenience to overall management and regional online operations.

[0006] ③ Narrow application level: the teacher can only use a single device to demonstrate the performance of the device with a single function for teaching, poor teaching application and low efficiency

[0007] ④Complicated installation, commissioning and maintenance: Because there are many types of teaching equipment and distributed in a decentralized manner, it occupies a large classroom area and the connection lines are complicated, requiring various professionals for installation, commissioning, maintenance and repair

[0008] At the same time, the way of using Zigbee in the Internet of Things in the prior art is to make a matching remote controller on the Zigbee device alone, and the remote controller can control some terminal devices fixedly, so that only closed information exchange in the network can be carried out. , did not solve the problem of Zigbee intranet and off-network intercommunication and integration

Some are to build a Zigbee communication module in the Zigbee device to realize the conversion of other commands in the 3G network to the middle of the intranet, but this kind of application is very limited, resulting in frequent modification of the command interface and command protocol. The device is fine, and it is fine as a demonstration or concept, but from a practical point of view, it is not a good way, and it cannot solve the problem of large-scale terminal devices communicating with the external network, and it does not represent the future development trend. Fully solve the problem of intranet and extranet conversion

In the traditional technology, many ways to solve the connection with the external network are through SMS modem, so there is a certain dependence on the telecom operator, and corresponding tariffs will also be generated
