To make it possible to quickly output a high pressure detection information during abnormal rise in gas pressure inside a pressure vessel, by providing means for outputting high pressure alarm data when a pressure corresponding to comparative pressure data is higher than the reference pressure at the high pressure side.
This monitor system 1 comprises a pressure monitor device 6 for alarm based on pressure detection, an analog-based local monitor device 7 connected to a corresponding pressure monitor device 6, a digital-based local monitor device 8 connected to a corresponding pressure monitor device 6, a first central monitor device 10 connected to an analog-based local monitor device 7, a second central monitor device 12 connected to the digital-based local monitor device 8, and a circuit operation section 13 outputting each operation signal. And high pressure alarm output means which received comparative pressure data compares a pressure corresponding to the comparative pressure data for each predetermined time interval to a reference pressure at the predetermined high pressure side, and, if a pressure corresponding to the comparative pressure data is higher than reference pressure at the high pressure side, then a high pressure alarm information is outputted.
