| Abstract: | This paper introduces the technology of RS-232 serial bus and the universal serial bus, discusses its anti-jamming, analyzes the reason of serial port producing error code and the USB deadlock phenomenon, proposes a solution of stable communication in data acquisition system under strong interference. Uses the RS-232 sending instruction, the USB sending acquisition data, when the communication deadlocks, initializes USB interface by the instruction, ensures the stability of communication under strong interference. |
