Abstract

The invention proposes a distributed supersonic air flow generating device operating state monitoring and emergency stop method. The method is realized based on a distributed measurement slave computer cluster and a measurement host computer, including: step 1) sampling of state representation parameters; step 2) parameter screening; step 3) each measurement slave unit checks the parameter The screened corresponding characterization parameter data is discriminated; step 4) when certain conditions are met, the measurement slave unit sends an early warning signal of the characterization parameter to the measurement host computer; step 5) the measurement host computer makes an early warning summary; The control host sends an "emergency stop" command to make the supersonic air flow generating device execute an emergency stop procedure. The present invention only needs to set and release the criterion table on the measurement host computer, and the workload is small; it does not occupy too many network resources, avoids data congestion, and reduces the risk of equipment damage due to untimely early warning.

Description

technical field

[0001] The invention belongs to the technical field of ramjet tests, and in particular relates to a method for monitoring the running state of a distributed supersonic air flow generating device and an emergency stop method. Background technique

[0002] The supersonic air flow generation device continuously heats the continuous supersonic air flow through liquid oxygen and alcohol combustion to generate a continuous supersonic high-temperature air flow, providing a supersonic high-temperature air flow simulation environment for the ramjet test. The supersonic air flow generating device has risks such as leakage of three high-pressure component pipeline media (liquid oxygen, alcohol, air) and device damage during operation, and it cannot be found in the supersonic air flow generating device through human visual observation. In the early stage of the risk, timely response confirmation and emergency shutdown of the device.

[0003] At present, the fault diagno...
