Integrated data transparent-transmission device based on script-embedded 3G/4G module

Abstract

The invention relates to an integrated data transparent-transmission device based on a script-embedded 3G / 4G module. The device comprises a power supply module, and the 3G / 4G module. The 3G / 4G module comprises a baseband chip, a radio frequency chip, a FLASH storage chip and an RAM memory. The baseband chip is connected with the radio frequency chip, the FLASH storage chip and the RAM memory; the baseband chip comprises an operating system unit, a data transparent-transmission control unit, a script set unit, a script interpreter unit, an application interface unit and a protocol stack unit. The data transparent-transmission control unit, the script set unit, the script interpreter unit, the application interface unit and the protocol stack unit are sequentially connected and are separately connected to the operating system unit. The device of the invention achieves the function which needs to be finished by an external MCU via an embedded data transparent-transmission script by using the relative strong processing capacity of the baseband chip of the 3G / 4G module, and removes the external MCU and relative circuits so as to save cost and reduce area.

Description

technical field [0001] The invention relates to the communication field, in particular to an integrated data transparent transmission device based on an embedded script 3G / 4G module. technical background [0002] 3G / 4G data transparent transmission unit (DTU) is widely used in industrial control, security monitoring, medical monitoring, agricultural transportation and other fields due to its convenient use, long transmission distance and wide coverage. 3G / 4GDTU is a wireless transparent data transmission device. The external device only needs to pass through the port provided by the DTU, such as a serial port, to transparently transmit the data to the remote end without considering the operation of the DTU itself, that is, the DTU part Treated as a transparent channel. DTU is a plug-and-play device, which shields the complex AT operation instructions and operation process of 3G / 4G modules. Users only need to connect to the port of DTU to realize data transmission. The com...
