Application of large data processing in traffic field

Traffic monitoring Large http://www.aliyun.com/zixun/aggregation/14345.html "> Data processing Program Advantages:

(1) by effectively improving the front-end equipment in all aspects of performance, increase the recognition function, increase the database record function, actually effectively reduce the user's purchasing cost, a device realizes many functions, effectively reduces the number of the platform, reduces a series of purchase, maintenance, operation and subsequent cost.

(2) through improving the transmission efficiency of the existing network equipment, realizing the fast transmission on the existing network and solving the bottleneck of the network, it can bring more rapid application experience and improve the service quality of the whole basic data.

(3) through the use of distributed storage to replace the existing central node storage, decentralized storage pressure, spread the data risk, the advantage is to prolong the data save time, reduce the risk of data loss, improve the access speed of each key data.

(4) Through the use of new database Hbase1 and embedded database SDB, through the distributed database, streaming platform data to improve the performance of the database system, but also improve the service quality of all applications, provide users with a more rapid application experience, improve work efficiency and service standards.

2, Application implementation

(1) To increase the function of front-end equipment to improve the stability of front-end equipment.

In the process of transformation from Pu Qing to HD, the storage of large amount of data is a common problem in the intelligent transportation industry. Boricai new generation of embedded HD smart camera, using integrated design mode, in each camera configuration 1T hard disk, used to store data. The front-end machine is equipped with large hard disk to solve the storage problem, which not only ensures the security of data but also ensures the efficiency of data transfer.

(2) The network transmission algorithm based on DNA packet is used to solve the network bottleneck.

The advantage of the network transmission algorithm based on DNA packet: The problem of low utilization rate based on traditional network bandwidth is solved. Traditional TCP adopts the technology of repeated connection, slow start, dynamic sliding window, timing retransmission and congestion control to ensure reliable data transmission, but it greatly reduces the bandwidth utilization and transmission efficiency. In this paper, based on the DNA packet transmission algorithm, the advanced transmission mechanism is used to improve the bandwidth utilization and transmission efficiency of the network greatly.

3, traffic monitoring large data processing application effect

(1) can give full play to the role of integrated machine, so that one machine can be at the same time high-speed, high-definition video capture, at the same time for high-definition image collection, to achieve rapid speeding, retrograde, red light, illegal turn and other illegal identification, to identify the license plate, vehicle type, vehicle color and other indicators, data can be uploaded at all times, One machine itself to achieve low power consumption, low failure rate, high stability on-line rate.

(2) can make full use of bandwidth to ensure that the normal bandwidth utilization can reach 50%-80%, peak can reach 90%-100%.

(3) The use of Low-cost servers and ordinary storage arrays, you can huff and puff the entire network bandwidth transmission data, do not lose data, data storage does not delay.

(4) database efficient operation, read and write speed significantly accelerated, service response speed significantly accelerated to provide fast and effective service.
