Diagnostic data transmission method, device, equipment and system

Abstract

The invention discloses a diagnostic data transmission method and device based on a diagnostic server, a diagnostic data transmission method and device based on diagnostic equipment, the diagnostic server, the diagnostic equipment and a diagnostic data transmission system. A data request task received by diagnosis equipment comprises at least two groups of data requests; correspondingly, the diagnosis server does not need to periodically send a data request to the diagnosis equipment; a plurality of groups of data requests are issued to the diagnosis equipment at one time; the diagnosis equipment acquires diagnosis data from a vehicle electronic control unit ECU according to the data request task and reports the diagnosis data to a diagnosis server; occupation of data transmission resources by a diagnosis data transmission mechanism of question-and-answer between the diagnosis equipment and the diagnosis server is avoided; therefore, a large amount of data transmission processes of issuing individual tasks to the diagnosis equipment by the diagnosis server are reduced, the problems of insufficient Bluetooth data transmission capability and the like are effectively solved, and logicimplementation of the diagnosis server is simplified.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a diagnostic data transmission method and device based on diagnostic equipment, a diagnostic server, a diagnostic data transmission method and device based on a diagnostic server, a diagnostic equipment, and a diagnostic data transmission system. Background technique [0002] With the progress of society, cars are becoming more and more popular. With the rapid growth of car ownership, the demand for car repair and maintenance services has also shown rapid growth, and the requirements for car diagnostic equipment are also getting higher and higher. Among them, the ECU (Electronic Control Unit) is used for the electronic control of various electronic equipment in the car, and realizes the real-time status data collection of the vehicle based on each device, laying the foundation for vehicle status diagnosis. Therefore, OBD (On Board Diagnostics) needs to communi...

Problems solved by technology

[0003] At present, the communication with ECU is based on Bluetooth communication, which is basically a question-and-answer diagnostic solution with a small amount of data. As the interaction with ECU becomes more frequent, the amount of interactive data becomes larger and larger. For the increasingly crowded Bluetooth wireless Communication, the communication of diagnostic equipment is slow and easily interrupted, which basically cannot meet the communication of big data, nor can it realize high-concurrency data diagnosis, and the user experience is poor
