Functions and pu12rposes:
USB (Universal Serial Port, Universal Serial bus) bus is the most widely used in the computer at present and at the most convenient time for the new interface, USB because of its easy to use, high speed, compared to other interface has significant advantages. But the USB interface is not initially designed for industrial application, application in the field of industrial automation control and data acquisition, especially for the high security requirements of the coal mining, chemical, medical industries, there is interference and potential risk of unsafe, even lead to disastrous consequences. And measurement method is to eliminate the potential danger of USB insulation, USB electrical insulation, can effectively eliminate the bus transient voltage or potential difference, avoid circulation, static, power and earth fluctuation when the damage to the computer or device and lead for the data is not correct, and ensure that the dangerous sites in the coal mine safety isolation equipment with the outside world, the safety of the human body in medical applications, etc.
