The invention relates to a safety power panel of a train interlocking and train control system and a safety monitoring method. A key equipment control and polling switching module detects input dynamic waves and other modules; the key equipment control and polling switching module cooperates with the dynamic wave absorption and driving module to convert dynamic waves into driving signals to drive the silicon rapid on-off and mechanical static isolation module; when the digital low-voltage side discrete safety guard module receives the failure signal, the silicon rapid on-off and mechanical static isolation module is irreversibly cut off; and the overcurrent protection and isolation cooperation module controls the input current. Compared with the prior art, the safety power panel has the advantages that the upgrading of the safety power panel is realized, the inherent fault natural gravity falling function of the gravity type relay is covered, the integral quick falling function of the dynamic tuning circuit and the gravity type relay is realized, and the arc adhesion protection performance of a large air gap of the gravity type relay is realized; and the target of reducing the cost is achieved on the premise of meeting the function safety.
