摘要
介绍基于通用分组无线业务(GPRS)通信技术在气体传感器检测中的应用,并成功地实现了数据的传输。气体传感器所检测到的信号由单片机AT89C51进行控制,可以由GPRS无线模块MC55输送到远方,终端是普通的可以接收短消息的手机。对测试装置进行了详细的介绍,并对该系统进行测试,结果表明:该系统可以稳定地实现定时或是实时传输数据。该系统成本较低,可以应用于化工、食品行业和毒气检测等领域。
The implementation of the GPRS communication technology in gas sensor is introduced, the data is transmitted successfully. The signal detected by the gas sensor is controlled by MCU AT89C51 and it can be transported to remote place through GPRS wireless module MC55. The terminal receiver can be a cell phone which can receive SMS. The whole test units are well introduced and relative tests are launched. The results show that the system is able to transmit both the real-time and fixed-time data stably. The cost of the unit is relative cheap, so it can be used in fields such as chemical Industry, foodstuff factory and toxic gas detection.
