Multi-parameter sensing urban underground pipe network monitoring method and system and related equipment

The invention discloses a multi-parameter sensing urban underground pipe network monitoring method and system and related equipment, and the method comprises the steps: obtaining a manhole cover state at a current time node, the manhole cover state representing that a mechanical micro displacement switch is in a closed state or an open state; if the mechanical micro displacement switch is in an off state, applying the multi-parameter monitoring instruction in real time, executing the multi-parameter monitoring instruction, and obtaining M underground state parameters; the underground state parameters comprise the well lid opening and closing state, the oxygen content, the carbon monoxide content, the hydrogen sulfide content, the methane content, the temperature and the liquid level; constructing an underground environment state vector by using the preprocessed M underground state parameters; inputting the underground environment state vector of the current time node into an underground pipe network monitorin
