After sharing the development trend of the Internet of Things in 2017, it will continue to share the development trend of the Internet of Things in 2018. This article is the seventh article on the development trend of the Internet of Things in 2018. Today we will discuss the improvement of the ecosystem on the edge of the Internet of Things!
Simplified version of the Internet of Things application
There is a joke: "A certain programmer decided to practice calligraphy after he retired, so he bought a lot of money in his four treasures. On the 1st, he had a sudden burst of Yaxing after a meal, some research on ink and a good sandalwood. Set a moment, ink, and solemnly, solemnly." Write a line: hello world!"
The general learning of the new computer language has a tutorial Tutorial, and the first lesson of the computer language tutorial is usually displayed on the screen "Hello world!"
When studying Xively in 2013, Xively had a Tutorial tutorial that demonstrated the following features:
1. Set the channel on Xively and associate the information channel with the positioning sensor of the mobile phone.
2. Configure a program on Xively to display the information of this information channel in the form of a web page.
3. Open the configured web page on the mobile phone and move the mobile phone. You can see that the latitude and longitude of the mobile web page on this page are constantly changing with the mobile phone.
The simplified version of the Internet of Things application framework is shown in Figure:
For the first program to get developers started, it is necessary for beginners to use the lowest technology thresholds to understand the functions of IoT applications in the simplest way. This starter program makes the most of the simplification:
1, borrow the sensor on the phone [does not have to prepare, configure the hardware].
2. It is not necessary to configure the network [the sensor and the mobile phone are on one system and do not need to configure the network for the sensor and directly borrow the network connection of the mobile phone].
3. Directly borrow mobile phone browser as the entrance of the application [The actual Internet of Things application can be a mobile phone App, it can also be a computer program, it can also be some special device applications, such as the application of a proprietary device].
This streamlined application allows beginners to experience the IoT functionality most quickly and easily.
However, Xively's more general introduction to the demo needs to include:
Sensor networking methods [directly connected to the cloud, or connected to the sensor network at the edge, and the sensor network is connected to the network through a router]; the operating environment of the sensor; more general-purpose applications.

The simpler the entry-level exercises, the better!
The popularity of Internet of Things applications is also starting from simple applications
From the introductory tutorial on the Internet of Things, the simpler and easier it is to start.
In the early days of the development of the Internet of Things, popular applications began to be popularized with the help of the perfect mobile application ecology [mobile application ecology].
As mentioned in the previous article, the navigation system is actually a very popular IoT application. Although the earliest navigation system was installed in the car, with the further popularization of navigation software, the navigation software of the mobile phone has become increasingly popular. The more popular.
There is a trend here: Proprietary device IoT applications, more integrated into mature, general-purpose application containers.
The generic mature application container here refers to a mobile application.
For example, proprietary car navigation software was replaced by mobile navigation software; the once popular bracelet function (recording movement status) was replaced by mobile phone functionality; the proprietary camera (card machine) was replaced by a mobile phone [includes some image sensing, of course] Function], The image sensing function combined with image and artificial intelligence is widely used (for example, the meter reading function of a water meter, the scanning application of a courier through a mobile phone), the exclusive recording equipment replaced by a mobile phone, and the like.
In real life, many traditional proprietary device tools have gradually been replaced by universal mobile phones [sensors + applications].
The main sources of the replacement of proprietary devices by general application containers (handsets) are the following:
1. The increase of sensors on mobile phones;
2. The perfection of mobile phone software development ecology;
3, equipment communication is not perfect.
The application of the earliest smart bracelet, there are few sensors on the mobile phone, need to transmit data through Bluetooth and mobile communication. After adding more sensors to the mobile phone, the function of the wristband can be replaced by the mobile phone, gradually the user of the smartband begins to decrease, and the users who use the mobile phone to step down begin to gain popularity.
After the ecology of the edge is improved, there will be the trend of equipment peculiarization
As mentioned in the previous section, proprietary devices will use general purpose application containers for functional integration.
In addition to the following: mobile phone development is ecologically sound; equipment communication is imperfect; and mobile phone sensor types have increased beyond these three reasons, and borrowing general-purpose devices can also reduce costs. This is also an important reason.
The special equipment needs to consider the cost and efficiency issues.
In the early stages of application, cost is the main consideration; however, with the popularity of applications, after the application of general-purpose application containers is large, efficiency will be another consideration.
If an application container hosts too many applications, switching between different applications will result in marketing efficiency. Therefore, after the application integration reaches a certain scale, there will be a reverse trend of device specialization.
When the edge of the development of eco-perfect, IoT communication protocol is perfect (Internet of things, high-speed communications 5G, medium-speed communications eMTC, low-speed and low-power communications NB-IOT and other agreements) deployed well; will form the development side of the edge of the ecosystem.
For example, the smart home system, the ecology with the central control system as the core, the ecology of wearable devices mainly based on mobile phone scheduling, and the smart manufacturing ecosystem based on MES scheduling, will be further specialized.
Taking the smart manufacturing ecosystem as an example, there is a relatively successful product maker's smart Newtonian system. (Early function generalization) is mainly a general protocol conversion system. The smart gateway of the craftsmen uses the Newton system to form a universal system. Gateway.
This universal gateway integrates the interfaces of various protocols and inevitably means an increase in hardware costs. When applied in industry, in a specific field, only two protocol conversions are required, so the hardware costs of other protocol interfaces are meaningless. When the demand for proprietary conversions is large, there will be demand for proprietary protocol-converted products.
Therefore, after such an ecological perfection, it will go back to the trend of hardware customization. The proprietary hardware is implemented on the basis of general-purpose software, which not only reduces the cost of hardware, but also makes use of the flexible configuration of common software to reduce the development cost of software.
The current stage
There are more and more Internet of Things applications nowadays, with the help of the mobile development ecology of mobile phones; and with the gradual progress of the Internet of Things's communication protocol, especially the operator's proprietary Internet of Things network, the network bottleneck is solved.
The application of Internet of Things is becoming more and more popular, and sensors are also enriched; now the edge of the ecology has taken shape. In the future, more mature applications will begin using proprietary devices.
For example, the smart home control system may be dominated by voice-controlled devices with large-screen functions instead of mobile phones as the main control terminal.
