From the first industrial revolution, the mechanized production of water and steam as the power, the second industrial revolution opened the electrical era, and the third industrial revolution accompanied the first PLC in the automation era to appear in the factory floor, producing intelligent Continuous improvement. Now in the fourth revolution, Industry 4.0, the continuous communication between the products produced and the machines on the production line not only optimizes the production process itself, but also allows the production process to flexibly adapt to market demands.
The concept of Industry 4.0 first appeared at the Hannover Messe in Germany. Nowadays, this concept and related intelligent manufacturing are popular all over the world, which is a hot spot and difficulty in improving manufacturing power today. In view of this, this issue of the Smart Industry Special Issue invites Suhel Dhanani, a senior technical expert from the Maxim's Industrial and Medical Division, to discuss issues related to the smart industry.

Industry 4.0 sensors will move toward miniaturization
Smart industry means the interconnection between sensors, communication gateways and advanced analytics engines to reduce operating costs, achieve downtime predictions, and optimize resource allocation in production processes. Suhel Dhanani said that the impact of this includes many aspects of the plant or plant equipment (system), which can be field sensors, controllers, PCs and other hardware systems, and the terminal equipment needs to interactively transmit useful data information, usually Connect to communication hubs, gateways, and switches to pass data to the cloud (or intranet) to form big data.
At the same time, once the data is placed in the cloud, the production resources can be optimized through different analysis and optimization software to achieve multiple tasks: system normal working hours, planned maintenance, efficiency, and more efficient use of resources. According to Suhel Dhanani, this is not all. Production data can be integrated into the manufacturer's ERP and CRM software, allowing us to not only schedule production processes and costs more efficiently, but also to modify assembly lines and process parameters in real time based on customer information.
It is worth noting that sensors are constantly being miniaturized and integrated. According to Suhel Dhanani, the picture shows the industry's smallest IO-Link ambient light sensor, which reads color values ​​and sends the information over an IO-Link link. The overall system is about the size of a paper clip.
Not only that, the IO-Link light sensor MAXREFDES23# also integrates six sensors: ambient light, red, green, blue, infrared and temperature. The light sensor uses Maxim IO-Link device transceiver, built-in 3.3V/5V linear regulator, configurable output (push-pull, pnp or npn), reverse polarity / short circuit protection, various fault monitoring. Suhel Dhanani emphasized that all components in this IO-Link optical sensor system have been carefully selected to ensure that the harsh operating conditions of the industrial environment are met.
Provide Corona reference design to optimize industrial sensing channels
Binary/digital sensors and switches are often used in industrial control, industrial automation, motor control and process automation applications. The system usually uses optocouplers to isolate each sensor channel. According to Suhel Dhanani, Maxim's Corona reference design provides front-end interface circuitry that greatly reduces the number of isolated optocouplers for programmable logic controller (PLC) digital input modules.
Corona subsystem design block diagram
The reference design accepts high voltage input (36V, maximum) and provides power and data isolation in a small package. Corona is designed to integrate an eight-channel, digital input level shifter/serializer (MAX31911), a data isolator (MAX14850), and an H-bridge transformer driver (MAX13256) for isolated power. The Corona digital input circuit solution is primarily used for digital input modules in applications such as PLC, industrial automation, process automation and motor control.
Mainly attack industrial video monitoring low-power power supply design
Suhel Dhanani said that the main direction of the company's video surveillance is the power solution. Two mainstream design trends in video surveillance are the continued miniaturization of cameras and the inclusion of major processing steps, so the system requires low power operation. Maxim's power solutions have the industry's smallest package size and power conversion efficiency of over 90%, so power consumption is only half that of competing solutions. (See below)
Overall, the strategic intention of the company's layout of intelligent industry is obvious, and industrial sensors are the top priority. Suhel Dhanani pointed out that research institutions have made different estimates for the size and development of the sensor market, but it is certain that as the level of analyzable data grows, so does the demand for sensors used to collect data. The compound annual growth rate (CAGR) for the entire sensor market is expected to reach double digits, especially for industrial sensors.
Finally, Suhel Dhanani emphasized that the term “universal measurement†(proposed by Emerson) means that sensors are ubiquitous, and that sensors can be implemented or will soon be realized in factories, refineries, chemical plants and other industrial plants. Collecting more process monitoring data can provide customers with a safer, more reliable, and more economical operation.
