The invention discloses a help-seeking information broadcasting method based on an intelligent door lock, a storage medium and an intelligent door lock. The method comprises the following steps that:whether a door lock opening signal is received within a preset time range or not is monitored; if not, inquiry information is sent out, wherein the inquiry information includes information indicatingwhether a target object is in a safe state or not; whether reply confirmation information is received within preset duration is monitored, wherein the reply confirmation information includes reply information for confirming that the target object is in a safe state; and if not, help seeking signals are sent to other door locks or terminal equipment capable of communicating with the intelligent door lock, so that users of other door locks can receive help seeking information in time. Therefore, dangerous users can be found and rescued in time; and problems of property losses and even personal safety caused by the fact that rescue is not carried out in time due to too late finding time are greatly solved.
