The application discloses a livestock and poultry farm gas monitoring system based on multi-point arrangement and relates to the technical field of livestock house gas monitoring.The system comprises an edge computing gateway, which identifies airflow stagnation dead angles and dispatches a track moving calibration robot to arrive above a target fixed sensing node according to the running state of a mechanical environmental control system through a reduced-order flow field proxy model; the robot constructs a local isolation zone and applies air pressure drop by using a concentric double-diffuser assembly, thereby triggering node wake-up; then, by means of a micro-heating assembly, a bypass pressure limiting valve and a pneumatic ultrasonic wave, low-damage peeling and residual gas extraction are implemented on the scabbed air-permeable membrane; subsequently, isogenic backfilling air masses are formed by maintaining outer ring diffuser gas supply, and a reference gas analyzer synchronously samples and updates drift compensation parameters or outputs replacement instructions with the target fixed sensing node; and the application can realize non-contact cleaning, in-situ calibration and long-term continuous recovery of the fixed sensing node in a strong turbulent livestock and poultry house environment.
