Abstract

The invention discloses a wireless data transmission method. The method comprises the following steps: sending a detection data frame to a server via a UDP (User Datagram Protocol) link after a user terminal successfully logins the server; judging whether detection feedback information which corresponds to the detection data frame and is returned by the server is received by the user terminal or not, wherein if received, judging that the detection data frame is successfully transmitted, and if not, judging that the detection data frame is unsuccessfully transmitted; and when N (greater than or equal to 1) detection data frames continuously sent by the user terminal are unsuccessfully transmitted, logining the server again via the user terminal. Meanwhile, the invention further discloses the user terminal capable of implementing the wireless data transmission method. The link detection process is established between the user terminal and the server, so that the data link is detected under the condition that the data communication is not influenced by the data, and thus the reliability of the data link is ensured. Therefore, the reliability of a data transmission process is effectively improved, and the high efficiency of data transmission is ensured.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a wireless data transmission method and a user terminal. Background technique [0002] In industrial applications, distributed wireless communication devices have the characteristics of concurrency, and have high requirements for real-time and reliability of data. The distributed wireless communication equipment adopts the wireless packet service, and realizes the data communication between the equipment and the user center server through the mobile operator network. When the device logs in to the mobile operator's network, the wireless communication device will be considered as online. At this time, if the network or service of the user center server is abnormal, the wireless communication device cannot communicate with the mobile operator because the data communication between the wireless communication device and the mobile operator is normal. If it is judged tha...
