Problems solved by technology
Among them, the USB to RS232 serial port can realize the communication between the computer and the serial port of the controlled device, but since there is no strict security inspection or inspection on the legality of the transmitted data, it may cause viruses or Trojan horses to be transmitted to the controlled device through the conversion device. equipment, cannot guarantee the security of the computer
For the RS232 serial port to USB communication method, the application scenario of this method is that in industrial production, the data in the industrial equipment is copied through the RS232 serial port to USB conversion device through the U disk, not for the transmission of keyboard and mouse commands. and conversion, limited application scenarios

The application discloses a method for converting a serial port protocol into a USB protocol for industrial control and related equipment, which are used to improve the security of data transmission of industrial equipment. The method is applied to a protocol conversion device, and the protocol conversion device is respectively connected to industrial equipment and computer equipment, and includes multiple data conversion modes such as blocking mode, white list mode, trust mode and cooperation mode. The method includes: receiving serial port data sent by industrial equipment; judging whether the protocol conversion device is in the target protocol data conversion mode; if so, converting the serial port data into target protocol data, and the target protocol data is USB protocol data; sending the target protocol data to computer equipment. Only when the transmitted data meets the requirements of the set mode can the subsequent conversion and data transmission steps be performed, avoiding the risk of computer equipment data leakage during the process of directly sending data from industrial equipment to computer equipment, and improving data transmission process security.
Description
technical field [0001] The present application relates to the field of industrial equipment control, in particular to a method for converting a serial port protocol to a USB protocol for industrial control and related equipment. Background technique [0002] In industrial remote control, the keyboard and mouse commands will be forwarded by the industrial equipment responsible for on-site communication forwarding to the computer used for production control through its own serial port to complete remote operation or control. [0003] At present, the serial ports of industrial equipment include RS232, RS485, RS422, etc. Taking RS232 as an example, in the actual application process, the serial port and USB communication methods of industrial equipment are generally divided into two types according to the data transmission direction: USB to RS232 serial port and RS232 Serial to USB. Among them, the USB to RS232 serial port can realize the communication between the computer and t...
