Data encryption and decryption system for road traffic flow data acquisition project and carrier device

Abstract

The invention discloses a road traffic flow data acquisition project carrier device. The device comprises a data processing device; and a display screen is fixedly mounted on the top surface of the data processing device. The data processing device is provided with a data input module, a cache module, a control signal module and an encryption and decryption module. The invention further discloses a data encryption and decryption system for the road traffic flow data acquisition project. Comprising the steps that road traffic flow data needing to be encrypted and a key are input into a data processing device through a data input module; characters input from the data input module are converted into ASCII codes to be output; and each key directly outputs a scan code. According to the invention, data acquisition can be carried out on road traffic flow, green travel is guided, the purposes of saving energy, improving energy efficiency, reducing pollution, benefiting health and considering efficiency are achieved, data in a transmission process can be encrypted, and meanwhile, the encryption and decryption module has relatively high transportability and configurability, so that the security of the data in the transmission process is improved.

Description

technical field [0001] The invention relates to the technical field of road traffic flow statistics and data encryption and decryption, in particular to a data encryption and decryption system and a carrier device for road traffic flow data collection items. Background technique [0002] With the development of my country's economy, the rationality of urban traffic infrastructure construction has become more and more important to the orderly connection of various social and economic activities in the city. The special planning of urban roads is an important part of urban planning. The basic work of the road system. Therefore, in the stage of road special planning, sufficient basic data is necessary for the determination of the final analysis conclusion of the plan. However, the traffic planning of cities in my country still reveals some big and small problems in different provinces and cities. Because in the collection of basic data, representative data is used for inference, ...

[0002] With the development of my country's economy, the rationality of urban traffic infrastructure construction has become more and more important to the orderly connection of various social and economic activities in the city. The special planning of urban roads is an important part of urban planning. The basic work of the road system. Therefore, in the stage of road special planning, sufficient basic data is necessary for the determination of the final analysis conclusion of the plan. However, the traffic planning of cities in my country still reveals some big and small problems in different provinces and cities. Because in the collection of basic data, representative data is used for inference, and errors are inevitable, which also causes problems such as the width of motor vehicle lanes, the width of non-motor vehicle lanes, and whether special bus lanes are set up in road standards. The determination is not reasonable, which leads to traffic congestion, air pollution and other problems. Carbon monoxide, hydrocarbons, nitrogen oxides, and fine particles emitted by motor vehicles in economically developed cities have become the largest source of air pollution in these cities. The development of the automobile industry has brought quickness and convenience to mankind, but it has also caused energy consumption and air pollution. Pollution damages human health and turns into a burden on the people's economy, causing great negative social impact.
