Dynamic balance smart city network bandwidth high efficiency data transmission method and system

Abstract

The invention provides a dynamic balance smart city network bandwidth high efficiency data transmission method and system; the method comprises the following steps: using a vehicle terminal to collect vehicle data; sending the vehicle data to a control center through the internet when the network works; storing the vehicle data to a data buffer area when the network fails; transmitting the data in the data buffer area to the control center when the network recovers; using a scheduling transmitter to control each time transmitted data bulk. The scheduling transmitter works in the following steps: obtaining each time data transmission time so as to calculate the average time T; obtaining the previous data transmitting time t and the data bulk n; calculating the next time transmitting best data bulk; determining whether the data in the data buffer area is bigger than m or not, if yes, controlling the next time transmitting data bulk to the internet as m; if not, sending all data in the data buffer area to the internet. The method and system are low in cost, stable in transmission, good in instantaneity, and the network is not easy to be blocked.

Description

technical field [0001] The invention relates to the technical field of energy Internet and smart city big data transmission, in particular to an efficient data transmission method and system for dynamically balancing the network bandwidth of a smart city. Background technique [0002] Nowadays, with the upgrading of Internet technology, people's demand for the Internet is also changing day by day. Urban transportation is the basis for the interconnection of things and things, things and people, and people and people. According to the development of technology, the concept of smart cities has emerged. At present, the construction of smart cities is still in the initial stage of exploration and development. It is mainly to conduct research on big data in the face of information collection and processing of sensing devices, and to discover and excavate effective data and key elements for smart city construction from big data. [0003] Big data plays an indispensable role in th...
