The invention belongs to the field of aircraft environment control systems, and particularly relates to a digital pressurization control system for double airtight cabins of an aircraft. According to the system, a cockpit pressure sensor is arranged in a cockpit, and a cargo hold pressure sensor is arranged in a cargo hold; the cockpit exhaust valve is arranged on the cockpit wall plate, and the cargo compartment exhaust valve is arranged on the cargo compartment wall plate; the inter-cabin balance valve is arranged on the inter-cabin partition plate; the cockpit safety valve is arranged on the cockpit wall plate, and the cargo hold safety valve is arranged on the cargo hold wall plate; the driving cabin negative pressure valve is arranged on the driving cabin wall plate, and the cargo cabin negative pressure valve is arranged on the cargo cabin wall plate; and the cabin pressure regulation control computer is used for collecting a pressure measured value fed back by the pressure sensor and controlling the exhaust valve and the inter-cabin balance valve. The requirement for respective pressurization control of the cockpit and the cargo hold can be met.
