Abstract

The invention provides a data transmission method, which is applied to a wireless link machine. The wireless link machine sets a plurality of data transmission channels in the system communication link, and stores them in the data transmission channels in sequence for multiplexing. In the periodic table; the method includes: receiving the data transmitted in the system communication link; identifying the data transmission channel for receiving the data; according to the data transmission channel for receiving the data, multiplexing the data transmission channel in the periodic table, the The data transmission channel next to the data transmission channel for receiving the data is set as the data transmission channel for sending the data; and the data is sent through the data transmission channel for sending the data. By adopting the technical solution of the present invention, multiple wireless link machines occupy the channels according to the set order to transmit data without interfering with each other, thereby meeting the requirement of multi-level extended coverage.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a data transmission method and a wireless link machine. Background technique [0002] The Police Digital Trunking (PDT) standard is based on meeting the needs of public security and police, and its application scope has gradually expanded to other industries, and it has gradually become one of the mainstream digital trunking standards in the world. In anti-terrorism, disaster relief, forestry, highway and other scenarios where the geographical environment is relatively complex, and common wireless coverage is prone to various blind spots, it is necessary to use the PDT standard to build an ad hoc link extension coverage system to achieve a complete emergency solution. [0003] At present, the transmission frequency of conventional services and link systems of the PDT standard is fixed. When constructing an ad hoc link extended coverage system, on the fixed transmis...
