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