The invention discloses a methane fermentation intelligent management system, belonging to a methane generating automation device and aiming at providing the system which can automatically manage intensification large-scale methane generation. The system comprises a computer, a field data acquisition device and a sensor; a sensor (3) arranged on all major devices of a fermentation system is connected with the field data acquisition device (2) by a communication cable; the field data acquisition device is connected with the computer (1) by the communication cable. The system not only realizes the conversion of the methane fermentation from the miniaturization production mode to the large-scale concentration efficient mode, but also intuitively displays all major processing equipment and all technological parameters by a configuration device through the sensor in a pattern or digital mode, conveniently realizes the monitoring of the whole production system, increases the working efficiency, has the advantages of low cost, high waste water processing efficiency, high gas generation rate and the like, and is the ideal management system matched with large-scale poultry and livestock farms.
