The fourth industrial revolution takes "intelligent manufacturing, intelligent production" as the core, and uses interconnection as a means to measure and test as an important core technology. The fourth work revolution is also the era of big data. It is the era of information technology. It is the comprehensive collection, comprehensive analysis and comprehensive application of all test information. In the process of application, new collection, new analysis and new applications are carried out.
In this process, timely, accurate and reliable measurement tests are ubiquitous. The challenge of metrology testing technology is comprehensive and omnidirectional.

1. Think about how to further improve the measurement and testing capabilities from higher accuracy, reliability, and consistency.

The accuracy, consistency and reliability of metrology testing techniques are the basis for the fourth industrial revolution. For example, in modern banking systems, to achieve global bank balances and expenditures must be consistent at a certain node, that is, the accounts are not subject to deviation imbalance, and the time accuracy of the bank computer system must be 10-6 or more, and if the world The industry needs to achieve 4.0, real-time docking balance, certainly higher than this precision, because the data is more, the industries, departments, industries, and enterprises involved are more complicated. Although the measurement accuracy of the current time has reached 10-15 or more, but this is only the data in the laboratory, can it be practically applied in the computer system? Can you meet the requirements? This is only the requirement of Industry 4.0 for time. What kind of requirements are there for length, temperature, electromagnetic, wireless transmission, etc? Can we meet? With the advent of the fourth industrial revolution, more precise measurement tests are required to provide test technology assurance.

2, should consider the development of instrumentation industry from the rapid development of sensing technology and the value transmission and traceability of sensors

Whether smart production or smart factories, sensors will be the direct source of data generation. A glass manufacturing company in East Germany installed more than 3,000 measuring sensors on a glass automatic production system to ensure the normal operation of the entire system. These sensors represent traditional instrumentation. So how to ensure that these sensors are accurate and reliable? How to pass them on value and traceability? Can I implement the self-calibration function of the sensor? The measurement sensor plus the software system realizes the function of the original instrument. Will the future detection instrument be replaced by various sensors or sensing systems? Where will the instrumentation industry go?

3. Should consider the verification, calibration or detection of measurement related software from the full application of embedded software and the rapid development of the Internet.

Whether it is Industry 4.0 or the Industrial Internet, “interconnection” is the core element driving this round of industrial revolution. The rapid development of interconnected technologies in recent years has also driven the rapid development of the software industry. System integration, remote transmission, and embedded software will become an important part of the test instrument, and the software and instrument will be inseparable.

Most modern measurement and test instruments can communicate directly with the Internet. Nowadays, more mature power meter reading systems have made the Internet an important part of it. Nowadays, metrological verification and measurement calibration are generally only for instrumentation, or only for the measurement and detection part. It is rarely involved in testing software acquisition performance, safety performance, reliability, and cheating. This management style must change in the future.

At the same time, due to the existence of software and the wide application of sensors, the possibility of simultaneous measurement of multiple parameters and multiple parameters by one system is greatly increased. The reliability of software and the ability to interconnect and interconnect technology will become an important factor affecting the fourth industrial revolution. So do we have software evaluation capabilities now? Can I verify or calibrate the entire system? Can I perform online verification of all parameters simultaneously?
