The invention provides a safety belt unfastening detection method, device and equipment and a medium, and relates to the technical field of automobile safety. The method comprises the steps that voltages at the two ends of a fixed-value resistor in a detection circuit are monitored, and the detection circuit comprises a safety belt lock catch switch, a seat occupying sensor and the fixed-value resistor which are connected in series; determining whether the safety belt is not fastened according to the value of the voltage; when the safety belt is fastened, the safety belt lock catch switch is in an off state, and otherwise, the safety belt lock catch switch is in an on state. When a passenger sits, the resistance value of the seat occupying sensor is lower than a first resistance value, otherwise, the resistance value is higher than a second resistance value, and the first resistance value is smaller than the second resistance value. Whether the safety belt is not fastened or not can be accurately detected, and the wire harness cost is low.
