Data input method based on OBD equipment

Abstract

The embodiment of the invention discloses a data input method based on OBD equipment, relates to the technical field of high-concurrency data processing, and can ensure timeliness of the real-time monitoring process of the OBD equipment and ease data congestion. The data input method based on the OBD equipment comprises the steps that data transmitted to a server by the OBD equipment according to a UDP / IP protocol are received by the server; the received data are taken out of a memory queue through the multi-service processing thread, the header of the received data is parsed, uplink entities are correspondingly generated according to the key words of the header, and the uplink entities are added to an uplink entity queue; downlink entities are generated according to the processing result of the uplink entity queue and pressed in a downlink entity queue, downlink messages are generated according to the downlink entities, and the downlink messages are added to a downlink information queue; and downlink information is issued to the OBD equipment according to the downlink information queue. The data input method based on the OBD equipment is suitable for data interaction with the OBD equipment.

Description

technical field [0001] The invention relates to the technical field of high concurrent data processing, in particular to an OBD device-based data storage method. Background technique [0002] At present, vehicles are widely equipped with OBD (OnBoardDiagnostic, on-board diagnostic system) terminals, and report data to the server in the form of high frequency. As the number of vehicles equipped with OBD devices continues to increase, the server needs to quickly analyze and store large amounts of data in quasi-real time. However, the traditional method of packet analysis and warehousing needs to be received and analyzed one by one before warehousing, which is difficult to meet the transmission requirements of high concurrency and large data traffic in the real-time monitoring process, so it often leads to data congestion and data loss. [0003] There are currently several compromise solutions, the main design ideas are: the OBD device directly uploads the read data to the mob...

However, the traditional method of packet analysis and warehousing needs to be received and analyzed one by one before warehousing, which is difficult to meet the transmission requirements of high concurrency and large data traffic in the real-time monitoring process, so it often leads to data congestion and data loss problems

[0003] There are currently several compromise solutions, the main design ideas are: the OBD device directly uploads the read data to the mobile terminal such as the user's mobile phone, and does not upload it to the cloud server for storage, but this makes the cloud server unable to process the data. In addition, it is difficult for the user's mobile terminal to effectively process the data reported by the OBD device; in some solutions, in order to ensure the success rate of data upload, the OBD device will also use the TCP / IP protocol for data upload, but The transmission method based on the TCP / IP protocol requires a more complicated handshake process, which consumes more communication traffic for users, and because the transmission process is more complicated, there is a delay in data transmission, and it is difficult to ensure the real-time monitoring process of OBD equipment. Timely nature, and it is easy to cause data congestion
