Satellite communication high-capacity channel parallel Internet of Things data receiving method

Abstract

The invention provides a satellite communication high-capacity channel parallel internet-of-things data receiving method, and the method comprises the following steps: 1, after a DCS satellite load is started, completing system state initialization; 2, enabling the data acquisition module (1) to perform periodic query; 3, when a data analysis module (5) periodically queries that a message exists in the data receiving memory pool, analyzing message receiving information; 4, enabling the data analysis module (5) to write the idle address into a heap in which the message information is stored; 5, when the data sending module (4) queries that the messages are stacked in the stored messages, reading the message with the highest priority and writing the message into a sending data cache region; 6, enabling a state information processing module (3) to update data storage and data receiving and transmitting states, framing the data storage and data receiving and transmitting state information and sending the framed data storage and data receiving and transmitting state information to a message sending cache region. According to the scheme, polling is carried out through the data acquisition module, temporarily stored acquisition data can be rapidly taken away, memory space is vacated for channels, and therefore the number of parallel access channels is increased.

Description

technical field [0001] The invention relates to a data communication method of the Internet of Things, in particular to a method for receiving data of the Internet of Things in parallel with large-capacity channels of satellite communication. Background technique [0002] According to the definition of the International Telecommunication Union, the Internet of Things is a network that solves the interconnection between items and items, people and items, and people. The space-based Internet of Things is based on the space-based communication network, and integrates space-based navigation, remote sensing and other services to provide a comprehensive information system for barrier-free interaction between objects and objects, people and objects, and people and people. In view of the characteristics of the space-based information system, the space-based Internet of Things has added many unique advantages compared with the traditional Internet of Things: [0003] (1) The communi...

Problems solved by technology

This scheme can improve the accuracy of reception (the satellite load will inform the ground sensor of the signal reception status through the response message or directly allocate the receiving channel), because the communication time of the satellite relative to the ground sensor is relatively short, and it is transmitted through the "handshake" method Data reduces the efficiency of data communication
