The invention discloses a fault information transmission method, device and system, equipment and a storage medium. The method comprises the steps of obtaining to-be-transmitted fault information of apower transmission line, encrypting the to-be-transmitted fault information according to a DES encryption algorithm to obtain encrypted fault information, and transmitting the encrypted fault information to a server. After the to-be-transmitted fault information is obtained, the to-be-transmitted fault information is encrypted through the DES encryption algorithm, the encrypted fault informationis obtained, and the encrypted fault information is transmitted to the server. After the to-be-transmitted fault information is obtained, the to-be-transmitted fault information is not directly transmitted to the server, but is encrypted firstly and then transmitted, so that the data security is ensured, malicious tampering is prevented, and the technical problem that potential safety hazards exist in the existing fault information transmission process is solved.
