AIOT is comming

The year 2019 is quietly passing by, and 2020, which I once looked forward to in my composition, is coming soon. Time flies by, and everyday life seems to be the same. However, 5G has been quietly laying out, artificial intelligence, cloud computing, big data and Internet of Things, which are no longer high-tech, are now penetrating into our lives:

  • How to deal with the power failure at home? Recharge online can ~
  • Why are there no hairpins at the gate of the community? Now we have license plate recognition
  • What if I forget my phone when I go shopping? What is the face to do
  • …

At the beginning, an iPhone changed our life greatly. Now, AI+IoT is in full layout, ready to welcome the coming era of AIoT. As a practitioner in the field of IoT, today I will unveil the mysterious veil of the Internet of Things Platform, namely IoT Platform.

1. Internet platform

When you use wechat to chat with your friends, notice that it is a point-to-point chat with your friends. It feels like you are whispering to each other, as if there is nothing wrong with you

In fact, this way of chatting is similar to passing notes in class. On the surface, it looks like you are chatting with each other, but in fact, you can chat with each other normally only after the transmission of many students in the middle.

Similarly, the message is not directly sent to your friend’s wechat by you using wechat, but your wechat, friends wechat are connected to the Tencent students this platform, between you all small notes are by Tencent students to help you complete the forwarding!

Tencent students, as an important Internet platform, quietly retire behind the scenes, leaving the stage to the wechat client, living in a secluded cave, forwarding small notes for us day and night, hard work ~

2. Internet of Things platform

Born in the Age of the Internet, wechat connects all of our wechat accounts to Tencent’s platform, so we can easily communicate.

In the era of Internet of Things, every object has a smart brain. They also hope to communicate with people conveniently, and we also hope to know what they are thinking, whether they are sick, whether they are working seriously and so on.

Humans and these intelligent devices, in urgent need of a small slip of classmate, can help them conveniently “pass a small slip of paper”!

This transfer student is what we call the Internet of Things platform.

3. Internet of Things platform, not just transit

The Internet platform connects people and forms a global village. As the core of AIOT era, the Internet of Things platform plays a role that is not only like the Internet platform, but also closely connects people and things.

Equipment on the cloud

Equipment and people, if you are indoors, so the preferred online way must be WIFI, if WIFI can’t use, just choose to use traffic, traffic is, after all, have to pay money, equipment, too, some of the smart home, factory equipment, originally this environment have LAN coverage, so there is no need to run to connect to the base station, Just connect to your own LAN.

In the outdoor equipment, such as smart logistics, trucks transporting goods run hundreds of kilometers every day, at this time, where to connect to WIFI, no matter how expensive the flow, right ~

Of course, there are also some differences between devices and people. For example, smart water meters can only send one data per week, or even one data per month. Can people only send one wechat message per week?

Therefore, at this time, there are some new cloud access methods suitable for these occasions, such as NB-iot to help devices connect to the network. In the future, facing different occasions, there will certainly be a variety of communication methods, there is no best, only better!

Device management, remote device upgrade

The intelligent brain of the device is endowed by our lovely programmers, it is like a good child, very obedient, but not flexible, how to do this?

Don’t worry! If the devices scattered to all corners want to upgrade some functions, you can write the bootloader program in advance. The Internet of Things platform can remotely transfer the bin file to the device to complete the remote upgrade. Isn’t it cool

Data reporting and command delivery

Mentioned before, people need a clear understanding of the working condition of equipment, so the Internet of things devices need every certain period to report back to the Internet of things platform own work status, such as street light/he detects the brightness values of wisdom, wisdom smoke alarm reporting their values detected smoke, vehicle report their own location data and so on…

When the iot platform detects that the iot data exceeds or is lower than the preset threshold, it can automatically send commands to iot devices for device control.

Users on the cloud

All of the features mentioned above can connect a variety of devices to the Internet of Things platform, but what about whether humans need to connect to the Internet of Things platform?

Of course! And that technology has been around since the Internet age.

People can connect to the Internet of Things platform through WIFI/4G network through wechat client, IoT client, small program, etc., so as to form a complete Internet of Things network:

  • Devices can report their own data to the Internet of Things platform, and in turn to users connected to the platform;
  • The user can send the control command to the Internet of Things platform, and then send it to the device;

AI on cloud

After connecting things and people to things, AI will also need to go to the cloud, and in the era of AIOT, AI and IoT will share the world.

IoT is responsible for the communication, connection, will be all over in every corner of the equipment in the world, will spread in various places in the world of human, because of the diversity of intelligent equipment and number, report to the Internet of things platform will be all kinds of data, and is very very very vast amounts of data, then these vast amounts of data by who to deal with?

Don’t worry, let me ask you a question first. When your eyes see a scene in front of you, what is it that makes a judgment, analysis, understanding of the scene? The answer is self-evident

Similarly, IoT feels the world just like our senses, but it also needs a brain to acquire valuable information from these data — AI. AI helps us process data, present data, analyze data, make judgments and make predictions. With AI, the whole IoT network is not wasted. Otherwise, why bother to use such a huge IoT network to feel every corner of the data?

IoT security

This problem I leave to last, because this problem is easy to be ignored, but does not mean that this problem is not important, on the contrary, IoT network can be popularized, just to see whether IoT network security is done!

  • When you buy a door lock, do you trust the Internet door lock? I think people will be more assured of the key ~
  • Does it freak you out when your smart lamp is connected to the Internet and all of a sudden it’s told to start working?

Technology is not guilty, however, should be protected against.

In the whole IoT network, equipment is connected to the Internet of Things platform, users are connected to the Internet of Things platform, so the security of the Internet of Things platform plays a crucial role. At present, the existing identity authentication mainly relies on layer upon layer authentication mechanism, and data transmission security is strengthened by TLS/DTLS. Otherwise, data transmitted on the platform cannot be accessed.

However, the Internet of Things is different from the Internet. After network security is well done, it is very likely to be directly cracked from hardware devices, such as smart locks. Therefore, from my personal point of view, IoT security still has a long way to go

4. Excellent Domestic Internet of Things platform

This part OF me hesitated for a long time to write, write more afraid of advertising suspicion, do not write and feel that this article owes a little heat, so I briefly or say ~

For those who want to learn IoT, congratulations, there is a free menu for you to choose, the platform is similar, but the platform of the big factory will have their own OS adaptation, there will be AI platform for you to use, pick one you look at the eye of the line:

  • Tact cloud
  • China Mobile iot platform Onenet (for OS: RT-Thread)
  • Huawei Cloud Oceanconnect Platform (for OS: LiteOS)
  • Tencent Cloud IoT Explorer platform (for OS: Tencentos-Tiny)
  • Alicloud iot Platform (for OS: AliOS, RT-Thread)

For engineers, if you want to carry out product development, these platforms are to charge, generally according to the number of your equipment and data traffic charge, so: specific situation, specific analysis!

After listening to my introduction, do you understand the role of the Internet of Things platform in the whole ERA of AIoT? In fact, the Internet of Things platform, really very important!
