The Design of the Temperature Auto-Monitoring System Based on GPRS

摘要

The system is constituted by the multi-point temperature sensing device in site, the GPRS wireless communication module and the temperature monitoring center. The data acquisition and processing of the temperature is achieved by the low-power and high-performance microcontroller MSP430F149. Based on the GPRS module controlled by the microcontroller serial ports, the temperature data is transmitted to the remote monitoring center through the link consisted by the GPRS network and the Internet. The establishment of the data listening and receiving in the monitoring center is through the Socket. The temperature data is saved in the Access database and database developed using Visual Basic, which enhances the effectiveness of the database management.
