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.

为了在工业生产及过程控制中准确测量温度,设计了一种基于低功耗MSP430单片机的数字温度计。整个系统通过单片机MSP430F1121A控制DS18B20读取温度,采用数码管显示,温度传感器DS18B20与单片机之间通过串口进行数据传输。MSP430系列单片机具有超低功耗,且外围的整合性高,DS18B20只需一个端口即可实现数据通信,连接方便。通过多次实验证明,该系统的测试结果与实际环境温度一致,除了具有接口电路简单、测量精度高、误差小、可靠性高等特点外,其低成本、低功耗的特点使其拥有更广阔的应用前景。 Abstract: In order to obtain accurate measuring temperature in industrial production and process control, a digital thermometer based on MSP430 MCU is designed. The system uses MSP430F1121A MCU to control DS18B20, and gets the temperature data, which is displayed on the LED. The temperature sensor DS18B20 and MCU transmit data through serial communication. MSP430 series has ultra-low power and high integration, DS18B20 only needs one port to achieve data communication. Through many experimental results prove, this system is consistent with actual environment temperature. The system has characteristics of interface circuit simple, high measuring accuracy, minor error, high reliability, besides, the characteristics of low cost and low power make it having vaster application prospect.
