Data communication terminal based on dynamic polling protocol

Abstract

The invention discloses a data communication terminal based on a dynamic polling protocol. The data communication terminal comprises a formatting processing module, a data transceiving processing module, a communication protocol module, a parameter setting module and a channel module. The communication protocol module is used for executing a dynamic polling communication protocol and controlling the data transceiving processing module to perform transceiving processing; corresponding operation is executed according to a preset terminal type; if the terminal is set as the master station, the polling levels of the sentinel stations are compared, service time slots are allocated to the sentinel stations according to the polling level sequence, and allocation information of the service time slots of the sentinel stations is sent through the data transceiving processing module; and if the terminal is set as the sentinel station, the data transceiving processing module is controlled to sendservice information according to the service time slot allocated by the master station. According to the invention, the opportunity of sending information by the sentinel station data communication terminal is improved, the real-time performance of sending information by the sentinel station in the network is improved, and the flexible network access of a new platform is realized.

Description

technical field [0001] The invention relates to a data communication terminal in a wireless communication network, in particular to a data communication terminal based on a dynamic polling protocol. Background technique [0002] The data communication terminal used for wireless network communication is a key device for multiple users to complete tasks such as information interaction and collaborative operation. The channel access method adopted by the data communication terminal is the core of the wireless communication network to complete information interaction, which has an important impact on the network performance and topology of the wireless communication network. The core of the problem is to enable users in the network to coordinate and arrange channels. Use of resources to achieve conflict-free information exchange. [0003] Polling is a typical controlled channel access method. Compared with time division multiple access, polling method can dynamically allocate c...

Problems solved by technology

[0005] It is precisely because of the existence of the above two disadvantages that when the quality of the transmission channel is not good, the data communication terminal of the outpost will not be able to send the response information for a long time because it cannot receive the inquiry information from the data communication terminal of the master station. , that is, the outpost data communication terminal cannot send business data for a long time; thus, it is difficult to guarantee the real-time performance of the outpost business data transmission, which seriously affects the information exchange and collaborative operation between users in the network

[0006] Not only that, in the existing polling wireless communication network, new members outside the network cannot realize random access to the network, and the network flexibility is very poor; however, the application scenarios of data communication terminals change in real time. Changes in network members and timely adjustment of the composition and quantity composition, it is difficult to ensure that the scheduled tasks can be successfully completed
