Internet of things comprehensive experiment system

Abstract

The invention discloses an Internet of things comprehensive experimental system, which comprises a plurality of function expansion boards, a plurality of function expansion areas and a download debugging functional area, and is characterized in that each of the function expansion boards is provided with an expansion interface; each of the function expansion boards can be connected with any one ofthe function expansion areas through the respective expansion interface; each function expansion area is provided with a serial port debugging interface and an SWD downloading interface; and the download debugging functional area comprises a serial port debugging chip selection module and an SWD downloading chip selection module, each function expansion area is connected with the serial port debugging chip selection module through the respective serial port debugging interface, and each function expansion area is connected with the serial port SWD downloading chip selection module through therespective SWD downloading interface. The Internet of things comprehensive experimental system is clear in system architecture, strong in comprehensiveness, good in openness, convenient for management, user-friendly in development and interaction and high in development efficiency.

Description

technical field [0001] The invention relates to an Internet of Things comprehensive experiment system. Background technique [0002] The Internet of Things technology is to connect all materials and products to the Internet through radio frequency identification, sensors or other embedded devices to realize intelligent management, supervision and control. It is another wave of the information industry after computers, the Internet and mobile communications. [0003] The Internet of Things technology has broad development prospects. Our country pays close attention to and attaches great importance to the research of the Internet of Things, and has begun to focus on the cultivation and reserve of talents in related fields. In order to further adapt to the development of Internet of Things technology and related talent market needs, major colleges and universities and various vocational training schools across the country have successively set up courses related to network comm...

Problems solved by technology

[0004] The IoT test box currently used for IoT technology training and demonstration has the following disadvantages: (1) The input and output modules of the sensor nodes are single and not fixed, which is not conducive to laboratory management; Program download or serial port debugging in the functional area requires plugging and unplugging of the download cable or debugging cable, which is not conducive to development and debugging; (3) The sensor nodes in the experiment box have a single function and a small number, making scene training and demonstration impossible; (4) The power supply of each extended functional area cannot be independently controlled in the test box; (5) The communication between the test box and the computer is carried out in a wired manner, which is not conducive to development, debugging and data transmission; (6) Each extension in the test box There is only one way of communication between the functional area and the coordinator, which is not conducive to the expansion of knowledge and practical operation in the teaching process
