GPRS network wireless data transmission system for multi-point communication and method for the same

Abstract

The invention discloses a GPRS network wireless data transmission system for multi-point communication and a method for the same. The method comprises steps of establishing a plurality of services on a connection platform for performing synchronized communication with a plurality of GPRS network main stations, performing initialization on a serial module, an Ethernet module and a GPRS module, determining whether a SIM card is registered and whether the GPRS module accesses the network, determining whether all the services are started up, checking the communication states of all stations every once in a while and performing the corresponding processing, performing polling determination on whether the data cache of each station transmits the data and successively transmitting the data, performing polling determination on whether the data transmitted from stations exist, and transmitting the data to the Ethernet and the serial communication interface. The invention supports the point-to-multipoint transmission mode, can save the cost and space on the occasion where the data transmission is performed among multiple points, and can be applied in various industries in the Internet of Things, like the intelligent power grid, intelligent transportation, the mobile terminal, the supply chain automation, the industrialized automation, the environment protection, the gas phase, the telemetry, etc.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a GPRS network wireless data transmission system and method for multi-site communication. Background technique [0002] GPRS (General Packet Radio Service), is a wireless packet switching technology based on the GSM system, providing end-to-end, wide-area wireless IP connection. Because the GPRS network covers a large area and has good stability, it is widely used in various wireless monitoring systems. [0003] With the increasingly complex and diverse forms of wireless monitoring systems, there are more and more situations where field data is sent to different sites. For example, there are sites and preparations in the data center, and on-site data needs to be sent to the data center and on-site maintenance personnel. Making the data transparent transmission module capable of transmitting with multiple stations will solve this problem. [0004] The previous GPRS data tr...
