Method for data exchange between upper and lower platforms of system

Abstract

The invention discloses a method for data exchange between upper and lower platforms of a system, which comprises the following steps: the upper and lower platforms adopt a TCP client-server mode as atransmission mode; each of the upper and lower platforms comprises a packaging component, a sending component, a receiving component, an extracting component, an encrypting and decrypting component,a message analyzing component and a storing component, wherein the packaging component is used for assembling messages; the sending component is used for sending an encrypted message through a network; the receiving component is used for receiving network data; the extracting component is used for extracting the encrypted message from the network data; the encrypting and decrypting component is used for encrypting or decrypting the messages; the message analyzing component is used for analyzing a decrypted message; and the storing component is used for storing the analyzed message to a database. The method for data exchange between upper and lower platforms of the system in the invention solves the problem of no unified data exchange method between the upper and lower platforms of the system and improves the reliability, the stability and the real-time performance of data exchange of the upper and lower platforms of the system.

Description

technical field [0001] The invention belongs to the technical field of Internet data transmission, and in particular relates to a method for exchanging data between upper and lower platforms of a system. Background technique [0002] At present, with the development of the Internet of Things, various vehicles are equipped with GPS satellite positioning devices, and various management platforms collect the positioning data of the managed vehicles, such as the taxi platform collects the location data of the managed taxis, and the bus platform collects the location data Managed bus location data. However, there is no unified method for data exchange between the upper and lower platforms of the system, and data sharing cannot be effectively realized. Moreover, the positioning data has the characteristics of large data volume and strong real-time performance. Usually, the vehicle will report its position every few seconds. Data transmission puts forward higher requirements, and ...
