The invention relates to the technical field of elevators, in particular to an elevator car gravity sensing intelligent alarm system which comprises an inner light early warning mechanism arranged on the inner wall of a car in a roadway, outer early warning mechanisms arranged on the two sides of a floor entrance and exit of the roadway and a gravity early warning mechanism arranged on the car. The inner light early warning mechanism, the outer early warning mechanism and the gravity early warning mechanism are respectively connected with the control mechanism; the control mechanism is installed on one side of the top face of the lift car. The gravity limit value of the lift car in a static state can be tested through gravity early warning, and real-time early warning is achieved through lamplight. The gravity change of the dynamic lift car is realized through a speedometer and a gravity sensor, so that the dynamic early warning is realized; the safety use of the elevator is greatly improved, the life safety
