Design of wireless tension monitoring system with low-power consumption of scraper conveyors

  • 摘要: 针对现有刮板输送机刮板链张力监测系统存在易损坏、数据无法实时传输、精度较差和功耗过大等问题,设计了一套低功耗刮板输送机张力无线监测系统及适用于该系统的无线通信布置方案。该系统封装于刮板和中板内部,不会受到矿石的冲击和矿水的侵蚀,封装的同时加工出可供电磁波通过的信号溢出口,使张力数据通过无线方式传输。封装在下压板内的张力采集装置通过粘贴在刮板链上的应变片获取张力信息,张力信息通过无线方式发送给封装在中板内的数据接收装置,数据接收装置再将数据上传至上位机或LCD显示器,实现张力的实时监测。实验结果表明,该系统通过与改造过的刮板输送机部件配合,可避免矿石、矿水的冲击、侵蚀和井下电磁的干扰,完成在恶劣环境下刮板链张力的实时监测任务,有效解决了现有刮板链张力监测系统在恶劣环境下易失效、张力数据不能实时上传等问题;引入接近开关和休眠机制的张力采集装置的能耗可降至最低,休眠状态下的功耗约为工作状态的1/40,大大延长了系统使用寿命。
    Abstract: In view of problems that existing tension monitoring system of scraper chain of scraper conveyor is easy to damage, cannot transmit data in real-time, accuracy is poor and power consumption is excessive, a wireless tension monitoring system with low-power consumption of scraper conveyors and wireless communication layout scheme suitable for the system were designed. The system is encapsulated in the scraper and the middle plate, which will not be impacted by ore and eroded by mine water. At the same time, a signal overflow outlet can be processed for electromagnetic wave to pass through, so that the tension data can be transmitted wirelessly. The tension acquisition device encapsulated in the bottom pressing plate obtains tension information through the strain gauge pasted on the scraper chain, tension information is transmitted wirelessly to the data receiving device encapsulated in the middle plate, which then uploads the data to the upper computer or LCD display to realize real-time tension monitoring. The experiment results show that through cooperation with modified parts of the scraper conveyor, the system can avoid impact of mineral,erosion of mineral water and electromagnetic interference, and can complete real-time tension monitoring in harsh environments, and can effectively solve the problem that existing scraper chain tension monitoring system is easy to failure and ca't upload real-time tension data in harsh environments. The energy consumption of the tension acquisition device which introduces proximity switch and dormancy mechanism is reduced to the minimum, and the power consumption in dormancy state is about 1/40 of that in working state, which greatly extends service life of the system.
