An abnormal pressure real-time monitoring and high speed recording device is disclosed. It operates essentially by first using a pressure sensor to convert various pressures (e.g., liquid pressure, air pressure or oil pressure) to the weak voltage signal within 0.0001 second, and then, through a pressure signal amplifying module, inputting the readable signal respectively to a pressure surge detecting module, a negative pressure detecting module and a pressure alarm upper/lower limit module in order to detect the occurrence of abnormal signals due to high speed surge pressure, negative pressure or exceeding of upper/lower pressure limit and the like. In case the detected signal exceeds the criteria value, it immediately awakes a microprocessor within 0.0001 second to perform continuous signal pressure reading at 0.001 second and save to the memory, and then sends the alarm message to a remote monitoring device by way of a network module or else directly controls the in-field equipment for adequate emergent processes. Upon detecting the disappearance of abnormal signals by the pressure surge detecting module, negative pressure detecting module and pressure alarm upper/lower limit detecting module, it terminates the actions of pressure value reading and signal storage and then controls the microprocessor to enter into a sleeping mode to achieve the purpose of power saving.
