An automatic monitoring alarm system is designed to meet the requirements for the maintenance security requirements of a certain type of compressed air station. The automatic monitoring alarm system use signal isolation transmitter to acquire lubricating oil pressure signals oil temperature, water temperature, rotational speed signals, compressed air pressure, etc. The acquired signals is converted into digital signals and transmitted by microcontroller module. The automatic monitoring alarm system use STC12 as microcontroller. An embedded control program is operating in STC12 to implement process of signals display, threshold judgment and alarm. The automatic monitoring alarm system can monitor some key operation parameters of the compressed air station in real-time which is benefit for safe operation of the compressed air station.
