The World Economic Forum (Davos Forum) Annual Meeting 2016 will be held in Davos from 20 to 23 this month, with the theme of "Mastering the Fourth Industrial Revolution".
In our opinion, the decline of smart production (Industry 4.0) concept stocks (Industry 4.0 Index -28.8%) significantly exceeded that of the ChiNext Index (-22.2%) during the year; In 2015, the fundamentals of some intelligent production and industry 4.0 companies have improved significantly, and intelligent production-related affairs are expected to become the company's main business in 2016, and rapid growth in performance is possible, and intelligent production has risen to the national strategic level. Therefore, the theme of intelligent production is expected to become one of the themes of dedication and excess income in 2016, and the best time to lay out intelligent production has arrived.
Automation and industrial control systems are generally abbreviated as ICS (Industrial Control Systems), which is a special term used to describe industrial facilities and automation systems. In the ISA-99/IEC 62443 standard, an industrial control system refers to "a mobilization that includes personnel, hardware and software that can affect the safety and reliability of industrial processes", and generally has the following four functions:
1. Measurement - take the sensor data and use it as an input or direct output for the next processing;
2. Comparison – Compare the acquired sensor data with the pre-set data;
3. Calculation - Calculate pre-historical errors, current errors and subsequent errors;
4. Correction - Adjust the automation process based on the results of measurement, comparison and calculation.
The above four functions are generally completed by five components in the industrial control system:
Sensors – used to measure the physical parameters of the policy;
Converter – converts the measured electrical/non-electrical measurement into a usable electrical signal;
Transmitter - responsible for the transmission of electrical signals in the control system;
Manipulator - provides control logic and input and output interfaces for the entire control system; Actuator - used to change the manipulation process.

Attention to the solution of heat dissipation in the application of inverter - Xinjie
Assuming that the inverter has a long service life, heat dissipation must be carefully considered. Because the equipment failure rate of the inverter increases exponentially with the increase of temperature, the service life decreases. If the operating temperature rises by 10 degrees, the service life of the inverter will decrease.
