温度是工业生产中很重要的参数,它直接影响到产品的质量。本文提出了一种基于ATmegal6单片机的温度监测系统。该系统包括检测电路,数据显示电路、键盘接口电路、通信电路和报警电路五个部分。该系统能够对室温在一定范围内进行监测,当系统所监测到的室温小于最低工作温度或者大于最高工作温度时,报警装置就会发出报警声。此外,该系统测量的温度精度保持在±0.5℃,可以满足工业生产的要求。

为解决输油管道温度压力参数实时监测的问题,设计了以C8051F930单片机作为控制核心的超低功耗输油管道温度压力远程监测系统。现场仪表使用高精度电桥采集数据,通过433 MHz短距离无线通信网络与远程终端RTU进行通信,RTU通过GPRS网络与PC上位机进行远程数据传输,在上位机中实现数据存储和图形化界面显示,从而实现输油管道温度压力参数的实时监测和异常报警。经实验证明,该系统的12位数据采集精度满足设计要求,漏码率小于1%,正常工作时间超过5个月,能实时有效地监测输油管道的温度压力参数,节省大量人工成本,有效预防管道参数异常造成的经济损失和环境污染。 Abstract: In order to solve the problems on real-time monitoring of pipeline temperature and pressure parameters, the ultra-low power remote pipeline temperature and pressure monitoring system was designed by using the single chip processor C8051F930 as the control core. The high-precision electric bridge was used in field instruments for data collection, the 433MHz short-range wireless communication network was used to make communication between field instrument and RTU, the GPRS was used by the RTU to transmit data to the PC host computer, and the data was stored and displayed in the PC host computer, so the real-time monitoring and exception alerts of pipeline temperature and pressure parameters were achieved. The experiment proves that the system of which error rate is less than 1% over five months working with the 12-bit data acquisition accuracy can effectively monitor the pipeline temperature and pressure parameters in real time, it saves a lot of labor costs and effectively prevents environmental pollution and economic losses caused by abnormal channel parameters.
