摘要
为实现工业现场物料和液位远程实时监控,以STM32单片机为控制核心,采用时差法超声波测距原理结合GPRS技术实现超声波液位监测系统设计,实时采集数据通过互联网传递给监控端,实现远程监控并做实时记录。为降低温度对测距精度的影响,增加了温度补偿电路。上位机采用LabView软件开发,便于管理人员监控。该系统解决了传统现场仪表反馈不及时、布线复杂等问题。经测试表明系统运行正常,具有较好的精确性和稳定性,适合工业现场安装使用。
In order to realize the remote monitoring of material and liquid level in industrial field, the ultrasonic liquid level monitoring system was designed by GPRS technology and combined with the ultrasonic distance measurement technology. The STM32 is used as the core unit, the real-time data aretransmitted to the monitoring terminal through the Internet to realize remote monitoring and real-time recording. In order to reduce the influence of temperature on ranging precision, the temperature compensation circuit is added. LabView software is usedand it is easy monitoring by managers. Test results show that the system is running normally and has good accuracy and stability.
