How To Verify The Reliability Of Electromagnetic Compatibility Of Industrial Panel PC

- May 19, 2020-

In the industrial automation applications, due to the extensive use of various types of radio equipment and related industrial modules, the complexity of the electromagnetic environment at the industrial applications has greatly increased. Industrial equipment can cause machine failures in the presence of impulse noise, radiated electromagnetic fields, static electricity, lightning strikes, voltage fluctuations, etc. The stability of industrial equipment is becoming more and more important for industrial projects. The anti-interference test of industrial projects has been paid more and more attention. The anti-electromagnetic interference of the industrial panel PC is the key to keep stable in industrial project scenarios.

Electromagnetic interference (Electromagnetic Interference, EMI) is the electronic noise that interferes with the cable signal and reduces the signal integrity. EMI is usually generated by electromagnetic radiation sources such as motors and machines. Electromagnetic interference is an electromagnetic phenomenon that people have discovered for a long time. It was discovered almost at the same time as the phenomenon of electromagnetic effects. In 1881, British scientist Siveside published an article on "interference", which marked the beginning of the study of interference. In 1889, the British Posts and Telecommunications Department studied the problem of interference in communications, and began to study the problem of interference toward engineering and industrialization.

Industrial all-in-one computers (industrial panel PC), as human-machine interactive display devices widely used in industrial automation, industrial Internet, artificial intelligence, smart medical treatment, smart city, industry 4.0, smart manufacturing, and CNC machine tools, have more high requirements, especially in the field of industrial applications. The use of a large number of high-power equipment makes the electromagnetic interference of industrial projects stronger.

So, how to ensure good electromagnetic compatibility in industrial applications? First of all, in the R&D stage of the industrial computing platform, the engineering staff must carry out more than ten electromagnetic tests on each system, including the withstand voltage test, which is used to identify the degree of insulation of the product, that is to say, the use of withstand voltage test equipment for industrial integration. The machine is tested to check whether the product's external voltage, electromagnetic field and other changes have an impact on the stable operation of the machine.

At the same time, product R&D department must carry out ESD electrostatic protection inspection, using charge transfer caused by objects with different electrostatic potentials coming close to each other or direct contact, testing the anti-static effect of the product itself. It is also a change in the electromagnetic environment of the product under electrostatic environment Quality inspection. TAICENN industrial Panel PC TPC series can reach the EMC industrial-level standard, which meets many scenarios with strong electromagnetic interference.
For some special industrial projects, TAICENN uses our own design and development capability to do non-standard customized industrial computing hardware and other industrial computers. To further promote the good progress of industrial projects, TAICENN and our cooperated laboratories quickly and accurately test the designed samples for EMC/LVD performance. On the one hand, our pre-made laboratory certification can reduce the complication and cost of customer industrial verification, and improve the progress efficiency for customer industrial projects; once a certain problem occurs under the sample test, we can quickly solve the problem and pass the certification.
