Abstract

The invention discloses a data transmission method and a data server for a data collection terminal without a fixed IP address, and solves the problem of how to make the data server determine that the received data packets are provided by numerous IP addresses when the data collection terminal has no fixed IP address Which data collection terminal among the data collection terminals sends the technical problem. The method in the present invention includes: receiving a data packet sent by an unknown data collection terminal; parsing the data packet to extract the first identity contained in the data packet; judging whether there is a second identity identical to the first identity in the online terminal list. ID, if so, send the data packet to the application end, and execute the next step, if not, delete the data packet; judge whether the first confirmation signal returned by the application end is received, if so, return the second confirmation signal to the first Register the data collection terminal corresponding to the two identities, if not, resend the data packet to the application side.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data transmission method and a data server for a data collection terminal without a fixed IP. Background technique [0002] In the switch room, there are many monitoring terminals, such as electrical information monitoring terminals, environmental temperature and humidity monitoring terminals, and cameras. The various data collected by the monitoring terminal will be summarized through the data collection terminal, that is, the switch room, and then uploaded to the application side through the data server for processing and application. Due to the large number of data collection terminals, the data server needs to determine which data collection terminal the received data packet belongs to. There are two current methods: [0003] 1. Lease the APN service of the telecom operator, so that each data collection terminal and data server have a unique intranet IP, and the dat...
