针对传统的锚索测力计存在测量精度低、抗干扰能力差、测量结果无法自动上传、分析和处理的问题,本文设计了一种基于工业以太网技术的巷道锚索测力传感器。重点介绍了传感器的原理及软硬件实现方案。系统硬件以STC12C5A单片机为核心,利用精密扭矩测量模块实现锚索受力的精确测量,利用RTL8019AS以太网控制芯片,实现了数据通信和共享。系统可实时、可靠地监测井下锚索受力情况,并对可能发生的安全事故做出提前预警。 Aiming at the problems of low accuracy, poor anti-jamming ability, and unable to automatically upload, analyze and process the measurement results of the traditional dynamometer, this paper designed a roadway cable load cell based on Industrial Ethernet technology. Focus on the sensor principle and hardware and software solutions. System hardware to STC12C5A SCM as the core, the use of precision torque measurement module to achieve accurate measurement of anchor force, the use of RTL8019AS Ethernet control chip to achieve data communication and sharing. System can be real-time, reliable monitoring of underground cable stress situation, and make possible early warning of accidents.
