All hardware in the utility model is existing equipment, does not repeat them here.
Data transmission module of the present utility model comprises primary processor S3C2410, SRAM﹠amp; FLASH module, SIM4100 module, power module, SIM interface module, RS232/485/TTL module.Power circuit provides power supply for total system, because SIM4100 module electric current when carrying out data transmission is bigger, thus require power supply can provide big electric current, and have the fast current changing capability.The physical function that the SIM4100 module provides 3G to insert, interface circuit provide RS232 and RS485 interface and other control auxiliary signal line.3G network can use SIM card to come identification terminal equipment, so 3G data terminal module needs to install SIM card in use, and specifies the unique device id of acquisition, and data monitor center communicates according to the terminal recognition number of SIM4100.The SIM card circuit is the Card Reader part of SIM4100 module.SIM4100 module specific performance is as follows:
SIM4100 is a bimodulus TD-SCDMA module solution, and frequency of operation is 2010-2025MHz under the TD-SCDMA pattern; Under the GSM pattern, frequency of operation is three frequency 900/1800/1900MHz.The SIM4100 module performance is outstanding, is the choosing of the ideal of multiple wireless application.SIM4100 supports AMR voice, note/multimedia message, and upstream rate is up to 128Kbps, and downstream rate is up to 384Kbps.Embedded ppp protocol stack and ICP/IP protocol stack can be finished the conversion between serial data and the IP packet fast among the SIM4l00.
Primary processor is the control core of system, should select the embedded high-performance processor chips for use, and the S3C2410 processor is based on 32 8-digit microcontrollers of ARM920T processor cores, the highest 203MHz that may operate at of S3C2410 processor.Resource on the S3C2410 chip the is integrated quite abundant sheet.
