The invention discloses a real-time data acquisition system and a power failure data saving circuit and method thereof. When no power failure happens, a system control module saves real-time data acquired by the acquisition module of the real-time data acquisition system into a mobile storage device to conveniently carry out the copying and the backup saving of the real-time data. During power failure, the system control module switches the power supply of the real-time data acquisition system into the power supply of an energy storage module with a built-in energy storage capacitor through a power supply switching module, and the energy storage capacitor is used as backup electric energy so as to bring the advantages of low cost and wide applicable range. In addition, the system control module reads real-time time in a real-time clock module during the power failure, the real-time time is taken as power failure breakpoint time data to be stored in the mobile storage device with the breakpoint data collected by the acquisition module during the power failure, and the power supply of the acquisition module is cut off. Therefore, the power failure saving of the data is realized, the data can be accessed through the mobile storage device without energization, and the stability and the convenience of the data are improved.
