Monitoring management system for biogas supply system

The utility model discloses a monitoring management system for a biogas supply system. The biogas supply system comprises a biogas supply device for supplying biogas generated by a biogas generation device, a torch device and a first gas supply pipeline for connecting the biogas supply device and the torch device. The monitoring management system comprises a first pressure detection unit which is connected with the biogas supply device and is used for detecting the gas supply pressure of the biogas supply device so as to generate a first pressure detection signal; the controllable valve is installed on the first gas supply pipeline and used for being opened or closed so that the first gas supply pipeline can be connected or disconnected; the controller is electrically connected with the first pressure detection unit and the controllable valve and used for obtaining the first pressure detection signal from the first pressure detection unit and generating a valve opening signal or a valve closing signal accordi
