A system and a method for monitoring pressure inside a railway vehicle comprise a carriage pressure detection device, a control device, and an alarm device. The control device is configured to receive and process a pressure signal collected by the carriage pressure detection device, perform calculation on and analyze the collected data, and transmit an alarm signal to the alarm device as an alarm when a preset alarm condition is met. When a pressure protection device fails, pressure changes inside the vehicle are monitored in real time by the carriage pressure detection device functioning independently of the pressure protection device. As a result, overpressure failure can be promptly detected, and personnel can be quickly notified to deal with the malfunctioning component of the pressure protection system. In this way, the failure of the pressure protection system will not lead to excessive pressure changes inside the vehicle when the vehicle is in operation.
