A data transmission method and device

Abstract

The embodiment of the invention provides a data transmission method and device. The method comprises the steps that a networking node receives observation data which has a first preset format and is transmitted by a data acquisition transmitter; the observation data with the first preset format is encapsulated into observation data with a second preset format; the observation data with the second preset format are sent to a gateway node, so that the gateway node encapsulates the observation data with the second preset format into observation data with a third preset format and transmits the data to a data center. The method is applied to a field observation transmission system with the networking node, the gateway node and the data center. The networking node receives the observation data transmitted by the data acquisition transmitter, and uses a wireless self-organizing network to transmit the data to the gateway node. The gateway node uses a public mobile communication network or a local area network to transmit the data to the data center. The field observation data are accurately collected, transmitted and processed in real time.

Description

technical field [0001] The present invention relates to the field of observation, in particular to a data transmission method and device. Background technique [0002] The total area of ​​my country's cold and arid regions accounts for more than two-thirds of the country's land area. The ecological environment in the cold and arid regions is fragile, but they all contain indispensable resources for the national economy and have a prominent strategic position. The field observation system conducts scientific research by observing various ecological and environmental data in cold and arid regions. It plays an important supporting role in solving major national strategic needs, and provides an important basis for scientific research in cold and arid regions. The foundation of major engineering construction and sustainable social and economic development in the alpine and arid regions of western China has provided strong support for the construction and development of the wester...

Problems solved by technology

[0003] Most of the existing field observation systems are distributed in the harsh natural environment areas with high altitude, high cold and inaccessible people in large areas such as the transition zone of agriculture and animal husbandry, semi-arid area, arid area, and alpine area. Most of the observation data are collected using Manual collection is carried out, and data processing and transmission are difficult, resulting in poor real-time and accuracy of data collection, transmission and processing
