The invention provides an indoor gas safety monitoring intelligent terminal and a safety monitoring method, so as to solve the technical problem that the existing passive detection products can only make emergency treatment after an accident occurs. The terminal is provided with a redundant wireless connection and at least one wireless topology connection, and the indoor gas safety monitoring intelligent terminal establishes an uplink data link with an upper system through the redundant wireless connection and establishes a downlink data link with sensors and actuators through the wireless topology connection, which ensures the requirements for layout orientation and distance of diversity sensors in the living room or the kitchen, and is beneficial to the rapid adjustment of transmission links after the increase and decrease of the sensors and the actuators. At the same time, the use of redundant wireless connections ensures low latency and high availability of data transmission duringdata aggregation uplink and dense command data downlink in a plurality of downlink data links.
