Ocean Internet of Things general gateway data forwarding method based on Beidou satellite

Abstract

The invention discloses an ocean Internet of Things general gateway data forwarding method based on a Beidou satellite. Beidou satellite communication is taken as a center, research of a heterogeneous network data forwarding protocol is taken as a core, and three network protocols, namely a Beidou satellite short message protocol, an Ethernet and GPRS protocol and a ZigBee network protocol, are involved. In the scheme, data packing and unpacking need to be carried out again by researching a data structure construction and analysis protocol among three different networks; meanwhile, network address judgment between heterogeneous networks also needs to be carried out. According to the scheme, ocean data can be collected according to multiple working modes, and data unpacking, Beidou protocol packaging and Beidou short message transmission are carried out. Meanwhile, developed master station end receiving equipment can complete Beidou short message receiving, data analysis, packing and packet supplementing operations; therefore, data mutual transmission and communication functions which are not limited by address positions among heterogeneous networks are realized.

Description

technical field [0001] The invention relates to a data forwarding method for a general gateway of the marine internet of things based on a Beidou satellite, and belongs to the technical field of communication. Background technique [0002] my country has a vast territory, and its terrain includes plains, mountains, lakes, deserts, and sea areas. Although my country's communication construction ranks among the top in the world, and the construction area basically covers 2 / 3 of the country's land area, but for remote mountainous areas, near the sea, and large lakes And in desert areas, the wireless communication network is powerless. In addition, my country is a country severely affected by natural disasters. Even if there are communication networks in some disaster-prone plains, when disasters occur, the communication network will be damaged or even paralyzed, such as the 2008 Wenchuan Earthquake. How to communicate effectively, accurately, and efficiently has become a critic...

Problems solved by technology

However, marine communication does not have a reliable mobile network base station compared to land, so the offline data transmission method that needs to collect data at sea can only be collected and stored first, and then processed on land. This method has low communication efficiency.

If data forwarding is carried out through maritime satellites, the price is too expensive and the waste of channel resources is not suitable for real-time frequent big data transmission and communication

Beidou short message can carry out data transmission and communication in real time, and it is not restricted by geographical location, but Beidou short message cannot transmit data and communicate with other networks, which greatly affects the communication with the land communication network. Data sharing, thus reducing communication data processing efficiency
