The invention provides a remote diagnosis system and a remote diagnosis method. The remote diagnosis system comprises an interaction device, a virtual OBD device, a cloud server, a vehicle end OBD device and a diagnosed device, one end of the virtual OBD device is connected with the interaction device to receive a diagnosis instruction or send a diagnosis response, and the other end of the virtual OBD device is connected with the cloud server to send an OTA instruction packet or receive an OTA response packet; and one end of the vehicle end OBD device is connected with the cloud server to receive the OTA instruction packet or send the OTA response packet, and the other end of the vehicle end OBD device is connected with the diagnosed device to send a diagnosis instruction or receive a diagnosis response. According to the invention, the interaction device sends the diagnosis instruction and obtains the diagnosis response through the cloud server, and carries out corresponding processing on the diagnosed device in time.
Description
technical field [0001] The invention relates to a remote diagnosis system and a remote diagnosis method, belonging to the technical field of automobile remote diagnosis. Background technique [0002] At present, the diagnostic systems of most equipment are based on the site. Such diagnostic systems are relatively closed, and fault diagnosis, maintenance, and calibration will be subject to labor, cost, and geographical constraints. These constraints will directly affect the timeliness of diagnosis and customer satisfaction. satisfaction level. [0003] With the development of computer technology and communication technology, the remote diagnosis system can well solve the problem of the diagnosed object and engineering after-sales personnel in different places, completely break the geographical boundaries, and connect and transmit information through 4G or 5G network. The remote diagnosis system realizes the access to the network server to obtain the diagnosis information and...
