The invention provides a safety self-check system comprising a first pressure sensor, a second pressure sensor, a first power amplifier, a second power amplifier, a first A/D (analog/digital) converter, a second A/D converter, a controller and an alarm. The first pressure sensor outputs a first pressure signal. The second pressure sensor outputs a second pressure signal. The power amplifier amplifies the power of the first pressure signal. The second power amplifier amplifies the power of the second pressure signal. The first A/D converter converts the first pressure signal from an analog one into a digital one. The second A/D converter converts the second pressure signal from an analog one into a digital one. The controller performs data latching on the first pressure signal and the second pressure signal when an electronic key locking signal is received, and compares the first and second real-time pressure signals to a latch value when an electronic key unlocking signal is received, and outputs a safety pre-judging signal. The alarm sends out an alarm tone according to the safety pre-judging signal.
