The invention provides a dangerous goods supervision system and method based on Beidou short messages, and relates to the technical field of dangerous goods supervision. The method comprises the steps of inputting a to-be-identified fingerprint; verifying whether the fingerprint is a fingerprint pre-recorded by an authorizer holding the dangerous goods through a fingerprint identifier so as to carry out identity verification, and carrying out limitation processing on the use of the dangerous goods by utilizing fingerprint identification; carrying out sound code recognition on the sound of the dangerous goods according to a sound code recognition engine device; and uploading local data of the use time, the use place and the sound code identification information of the dangerous goods to a cloud end by using a Beidou short message. Real-time positioning is achieved through Beidou short message communication, modeling and recognition are conducted on sound through fingerprint recognition and introduction of a so
