Behind the IoT Internet of Things, prepare for Industry 4.0

The continuous development of the Internet has promoted the Internet of Things and Industry 4.0, and the whole world seems to become interconnected in an instant. Billions of sensors are assembled on billions of controllers and millions of gateways to transmit data to every corner of the globe via the Internet. This trend highlights the portability and inflexibility of traditional industrial systems. It is imperative to increase the efficiency of industrial systems and increase the added value of industrial production through IoT-connected networks and high-efficiency data processing. And this transformation relies on a range of technologies, from low-power wireless protocols to high-performance microcontrollers.

Low power wireless link and microcontroller

In these technologies, low-power wireless links and microcontrollers will play a vital role as the core of the entire link. For example, Silicon Labs recently introduced a Gecko microcontroller that uses this low-power mode—after receiving the signal from the sensor, the controller will start up accordingly, after sending the data. Automatically shut down. These microcontrollers can operate for up to 10 to 20 years using a 3.6V battery and can be applied to smart grid power distribution and sensor networks. Due to the extremely low power consumption, these devices are now able to provide energy through solar cells, even RF or thermal energy in the surrounding environment, eliminating the need for batteries or power cords.

At the same time, these devices also need to rely on the various protocols used in the Internet of Things. The 2.4GHz ZigBee mesh network is now widely used in the M2M (machine to machine) field, making it easy to add network nodes and link to network management equipment. The latest version of ZigBee IP has been upgraded to the IPv6 standard and supports the network. Direct access to the sensor node allows the user to control more devices.

The power of software

Software is another key element of the Internet of Things. Wind River has developed a complete software development environment based on the Intel architecture processor to provide users with out-of-the-box components to ensure the security of the IoT gateway. , interconnected, and managed on a unified platform. The software adds network management security and Lua, Java and OSGi application scenarios to support the development of portability, scalability and reusability of resource-constrained devices and full-featured devices, as well as WiFi, Bluetooth, ZigBee and others. The process wireless protocol provides support.

At the same time, other semiconductor suppliers have partnered with software vendors to provide users with a complete pan-IoT solution: Freescale Semiconductor has developed a secure “one box” platform with ARM and Oracle. The platform combines end-to-end software with a layered intelligent gateway to provide and manage secure IoT services, creating a common open framework. At the same time, the three companies also cooperated to simplify the development of ARM mbed project nodes. This will enable the native hardware abstraction layer (HAL) in ARM mbed to run Oracle Java ME Embedded software on ARM-based Freescale KineTIs microcontrollers.

Cloud computing can also be used to support such sensor nodes. Xively, a subsidiary of remote access software company LogMeIn, has developed the first public cloud platform for the commercial Internet of Things, which is currently working with Linear Technology to accelerate the introduction of ultra-low-power cloud networking products. By integrating Linear's Dust Networks wireless sensor with Xively's cloud services, the company can provide developers and original equipment manufacturers with a cost-effective end-to-end IoT solution through massive commercial deployments and Management can be used for early prototyping and validation.

Developed for IP compatibility, the ARM Cortex-M3 wireless sensor uses 6LoWPAN and 802.15.4e standard protocols to provide more than 99.999% data reliability and more than 10 years of battery life, making it the most extreme environment. It is possible to deploy a wireless sensor network. An introductory kit includes sample application code that Xively registered users can use to connect DC9000 devices to networked computers to help IP sensor networks automatically register as Xively "products"; nodes and sensors can be used as "devices" "Send data securely to the user's Xively cloud.

The rise of new technologies

There are also areas where development is taking place: low-power WiFi is now starting to use low data rates and fast data transmission technology, which greatly extends battery life while reducing costs through mass shipments. At the same time, the Bluetooth Low Energy (LE) application in Bluetooth 4.0's latest standard edition also supports ultra-low-power network connectivity, which has already shown results in increasing consumer electronics sales and reducing costs, while in the application of the Internet of Things, People's interest is also growing.

This strong interest has also driven the birth of many new technologies, such as the Weightless protocol developed specifically for IoT applications. All sensors and controllers need to be connected to the gateway, and large chip companies are ready to face this market. Texas Instruments has simplified the design by integrating MAC and Ethernet physical interfaces into ARM-based microcontrollers. Texas Instruments' latest device is the first ARM Cortex-M4 controller with Ethernet MAC+PHY and core-loaded data protection and LCD controllers, which can significantly save board space and be used for networking applications such as home/building automation gateways, networked people Machine interaction interface (HMI), network sensor gateway, secure access system and programmable logic controller - provide support. CAN provides an integrated high-speed USB and networking performance, such that the solution creates a seamless gateway program becomes possible, through the I2C port 10, two fast and accurate 12-bit analog to digital converter (the ADC), two orthogonal Encoder excuses, three core-load comparators, an external interface, and an advanced Pulse Width Modulation (PWM) output interface facilitate the aggregation of sensors for illumination, sensing, motion, reality, and switching.

In the era of Industry 4.0, electronic component companies must not only seize opportunities, but also anticipate opportunities. The above mentioned aspects highlight some of the trends behind the Internet of Things: sensors and devices that are increasingly compatible and support multiple protocols are being heavily demanded, while software environments, end-to-end deployments, and application development are emerging. A place of your own. This trend will further stimulate growth in R&D and shipments while reducing costs. Companies that want to catch up with Industry 4.0 “torrents” should pay more attention.
