Data transmission module and method based on GPRS network

Abstract

The invention discloses a data transmission module and method based on the GPRS network. The module comprises a control module, a storage module, a communication module, an external joint module and a power supply module; the control module is of a chip LPC 1768, the storage module is of a ROM connected to the control module, the external joint module is connected to a Uart joint of the control module, the communication module comprises a GPRS module and a plurality of sim card grooves, the sim card grooves are connected to the GPRS module, and the GPRS module is connected to the Uart joint of the control module. The method includes starting a safeguard mechanism, accessing to the GPRS network, and transmitting the data. According to the module and method, the advantages of the GPRS network of wide environment covering range and high cost efficiency, reestablishment or additional network facility purchasing are omitted, and the accurate remote data transmission is implemented by means of the GPRS wireless network efficiently and stably.

Description

technical field [0001] The invention relates to the field of GPRS wireless network, in particular to a data transmission module and method based on the GPRS network. Background technique [0002] Nowadays, in many fields such as smart grid, smart home, remote monitoring, data collection and Internet of Things, a realistic problem is that collection devices are often independent and scattered throughout the system. Teleportation has always been a more complex problem. For a long time, the technology of remote data transmission using optical cable, ultrashort wave, power line carrier, satellite communication, etc. The means are only used in a relatively narrow field and cannot be popularized universally. The problem of remote data communication has become a bottleneck restricting the development of the entire field. [0003] GPRS (General Packet Radio Service) is a packet-switched data bearing and transmission method developed on the basis of GSM, providing end-to-end, wi...
