Remote communication system based on TD-LTE (time division-long term evolution)

Abstract

The invention provides a remote communication system based on TD-LTE (time division-long term evolution). The remote communication system comprises a data control device, a portable mobile intelligent terminal, a data protocol conversion device, a lower computer, an Ethernet network system and a TD-LTE network system, wherein the data control device is connected with the portable mobile intelligent terminal, the data protocol conversion device and the lower computer through the Ethernet network system and the TD-LTE network system; the portable mobile intelligent terminal, the data protocol conversion device and the lower computer are orderly connected. Through the adoption of a small and portable embedded database platform, the remote communication system can support the distributed operation, that is, a client and a server can be located on different hosts, the frequent data processing and interface updating are separately designed, so that the communication efficiency of the system is effectively improved; and meanwhile, the operation that a user remotely accesses lower computer equipment becomes true, the remote data communication in the whole network range can be realized, and the background data center mobile working can be realized in the support of the TD-LTE network.

Description

technical field [0001] The invention relates to the field of long-distance communication systems, in particular to a long-distance communication system based on a TD-LTE network. Background technique [0002] At present, GPRS is a bearer service developed on the existing GSM system. The purpose is to provide GSM users with data services in the form of packets. This service is an efficient and low-cost wireless packet data service, especially suitable for intermittent, burst It is suitable for sporadic and frequent small amount of data transmission, and also suitable for occasional large amount of data transmission. Based on these characteristics, GPRS is widely used. For our country, GPRS network is also widely used to realize long-distance communication, but the technology is relatively immature, and there are some problems: the intelligent data transmission module itself does not have a packaged transmission protocol (complete transparent transmission), although it is easy...

AI Technical Summary

Problems solved by technology

For our country, GPRS network is also widely used to realize long-distance communication, but the technology is relatively immature, and there are some problems: the intelligent data transmission module itself does not have a packaged transmission protocol (complete transparent transmission), although it is easy to use, the communication quality is not good. Reliable; the intelligence of the background data center is not high, and it does not support multi-tasking at the same time; the database platform used is bulky and occupies a lot of space; the mixed design of the client and the server makes the data processing and interface update share the same process, resulting in software failure during communication. The execution speed is relatively slow; serial devices with different protocols cannot be accessed uniformly
