Embodiment 1

[0041] See figure 1 , Shown is a schematic structural diagram of a mass data storage and retrieval system for a new energy vehicle in Embodiment 1 of the present invention, and a mass data storage and retrieval system for a new energy vehicle, including a vehicle terminal 11, a load balancing server 12, a cache server 13, The timing archiving scheduling module 14, the distributed file manager 15, and the retrieval request module 16, in which,

[0042] The output of the in-vehicle terminal 11 is connected to the input of the load balancing server 12; the output of the load balancing server 12 is connected to the input of the cache server 13; the output of the cache server 13 is connected to the input of the timing archive scheduling module 14 and the retrieval request module 16 respectively; The output of the timed filing scheduling module 14 is connected with the input of the distributed file manager 15; the output of the distributed file manager 15 is connected with the input of ...

Embodiment 2

[0045] See figure 2 , Which is a schematic structural diagram of a mass data storage and retrieval system for a new energy vehicle according to an embodiment of the present invention.

[0046] The cache server 13 includes a memory queue 131, a detection processor 132, an index file library 133, and a data file library 134. The input of the memory queue 131 is connected to the output of the load balancing server 12; the memory queue 131 is connected to the input of the detection processor 132; The output of the processor 132 is connected to the input of the index file library 133, the data file library 134, and the retrieval request module 16 respectively.

[0047] The detection processor 132 determines whether the number of data packets in the memory queue 131 reaches the threshold according to the preset data flushing threshold; and analyzes whether it is real-time data, historical data, and cold data when the retrieval request module 16 issues a data retrieval instruction. If th...

Embodiment 3

[0049] See image 3 , Which is a schematic structural diagram of a mass data storage and retrieval system for a new energy vehicle according to an embodiment of the present invention.

[0050] The distributed file manager 15 includes a cold data file library 151, a Hadoop module 152, and a distributed file cluster 153. The input of the cold data file library 151 is connected to the timing archive scheduling module 14, and the output is connected to the input of the Hadoop module 152; The output is connected with the input of the distributed file cluster 153; the output of the distributed file cluster 153 is connected with the retrieval request module 16.

[0051] When the timing archiving and scheduling module 14 determines that the data file in the data file library 134 is cold data, it will be transmitted to the cold data file library 151, and then the data in the cold data file library 151 will be fragmented by the Hadoop framework of the Hadoop module It is stored in the distri...

Abstract

The invention discloses a massive data storage and retrieval system and massive data storage and retrieval methods for new energy vehicles. The system comprises a vehicle-mounted terminal, a load balance server, a cache server, a regular archiving scheduling module, a distributed file manager and a retrieval request module, wherein the output of the vehicle-mounted terminal is connected with the input of the load balance server; the output of the load balance server is connected with the input of the cache server; the output of the cache server is connected with the inputs of the regular archiving scheduling module and the retrieval request module; the output of the regular archiving scheduling module is connected with the input of the distributed file manager; and the output of the distributed file manager is connected with the input of the retrieval request module. The invention provides a storage system for massive internet-of-vehicles real-time data of the new energy vehicles to solve the problems of finite system capacity, low storage and retrieval speeds and archived data storage and retrieval of a conventional database.

Description

Technical field [0001] The invention belongs to the field of data processing, and particularly relates to a mass data storage and retrieval system and method for new energy vehicles. Background technique [0002] With the development of computer technology and the improvement of automation, many applications that have time constraints on data access and management have emerged, such as power system scheduling, industrial control, securities trading, aerospace and so on. These applications usually require real-time sampling of equipment to understand the latest status of system operation, so the acquisition frequency is very high, reaching 25, 50 or even 100 frames per second; at the same time, all data within a specified period of time must be completely saved, which requires the maintenance of massive amounts of data ; And it is required to collect, process and respond correctly to the data within the specified time or time range, which has obvious timeliness. With such massive...
