The invention relates to a circulation strategy parameter inhibiting method of onsite debugging and test. The method is realized by a valve-based controller (VBC). The method comprises that a debugging parameter is set in a man-machine interface of a host computer of a valve monitoring unit; a light transmitting interface is added to the valve monitoring unit, and a debugging parameter and a fiber communication signal are sent to an arm current control unit; a reception interface is added to the arm current control unit, and condition of reception information is polled and scanned; a parameter correcting and debugging program is added to the arm current control unit, and according to the reception information, the debugging condition and a strategy parameter are changed repeatedly till debugging is optimized; and a debugging result is combined with a parameter setting result, application modules of the VBC are updated in a unified way, interface debugging and parameter correcting programs are removed, and engineering application is completed. According to technical schemes of the invention, a concrete debugging process in which software codes are modified repeatedly in a worksite is avoided, and the hidden risk in complex strategy debugging and parameter setting process are avoided.
