GPRS-based Remote Temperature Monitoring System

In industry control field, it has the important significance in the remote dataacquisition and transmission system. In many industry cases of our country we need tocollect data at fixed time to know the locale situation in time, especially for somedistributed and no watcher locale. The traditional mode of remote data collection andtransmission system implementations generally require their own construction andmaintenance of wired or wireless communication networks, investment andmaintenance costs are very high. The embedded Internet technology enables electronicinstruments existed in many fields to access Internet, which makes remote detection,remote control, remote maintenance and remote data acquisition easy.The far-distance temperature monitoring system system based on the GPRS ismainly used in holiday peak times, especially in Spring Festival holiday and summervacation period the compartment temperature is always too high or low, so we need tomonitor remotely the temperature in time to avoid the phenomenon. So that passengerscan have a relative comfortable journey. After a lot of literature is proposed, based onthe GPRS wireless technology and other relative advantages of technology, and putforward the remote temperature monitoring system, I have put the overall design of thesystem. Then on the data acquisition terminal of the hardware, software design,realizing remote terminal and the design of monitoring and control system based onGPRS DTU module data transmission. Finally summarizes the design scheme researchachievements and existing problems.
