Description

Internet of things transmission communication method based on real-time shared storage and micro device

Technical Field

The invention belongs to the technical field of communication devices, and particularly relates to a real-time shared storage-based Internet of things transmission communication method and a micro device.

Background

With the continuous development of computer technology in recent years, there are various ways and methods for reading device data remotely. Local area network sharing, NAS network storage and the like are typical.

NAS is a representative network data sharing method and technique that provides a common interface on the network for sharing the same storage medium. Computers in the network access a common storage medium in the same manner as a plurality of nodes.

The sharing of data by the local area network allows a user of a computer in the same network to read and modify data stored on another computer.

The two ways are only limited to computers and a few devices with network data sharing function. Instruments, equipment and controllers for many professional purposes do not have network interfaces, but often only provide an external memory interface, and storage media such as a USB flash disk can be inserted into the external memory interface for reading and writing; after use, the storage medium needs to be removed and inserted into a computer or other device to read and write the storage medium. Instruments, equipment and controllers of this type are widely used in factories, hospitals, schools, scientific research institutions, laboratories, rural areas and mobile vehicles. It is only the connection of these devices to obtain or share data that is the true basis of the internet of things,

a device similar to a wireless USB flash disk is available on the market, is similar to a common USB flash disk in shape, and can access data on the USB flash disk by using a wireless network. But the U disk function and the wireless network disk function cannot be used simultaneously.

In practical applications, each instrument, device, controller, and sensor or a group of instruments, devices, controllers, and sensors may be equipped with a computer or a dedicated device to implement the internet of things.

To summarize, the current implementation situation of the internet of things related to the present invention is:

1. the Internet of things environment is severe, and the reliability of data cannot be guaranteed.

2. The cost is high, and the expense of the Internet of things is often several times or even dozens of times higher than the target of the Internet of things.

3. Point of distribution of things

4. The data acquisition of the internet of things target has various protocols and rules, and is hampered by confidential means and industry.

5. The equipment protocol and the rule for realizing the internet of things after networking are various and are kept under the control of secret means and industry.

There is currently no unified, efficient and low cost solution to the above-mentioned situation.
