针对早期的各类矿井深度指示器的不足,为了减小该设备的体积,提高其指示和测量精度,提出了以DSP为核心单元处理的具体系统实现方案,利用DSP电动机速度监测的正交编码脉冲单元和高速信号处理能力实现矿井的数字化深度监测与指示。研究了DSP与主控系统PLC的通信问题,列出了相应的程序流程图。在实验室条件下的测试结果表明,各项试验指标均达到了设计的要求。
In order to reduce the size of the equipment and improve its indication and measurement accuracy, aiming at the shortcomings of all kinds of early mine depth indicators, a specific system implementation scheme with DSP as the core unit processing is proposed. By using quadrature coding of DSP motor speed monitoring Pulse unit and high-speed signal processing capabilities to achieve the mine’s digital depth monitoring and indication. The communication between DSP and PLC is studied, and the corresponding program flow chart is listed. The test results under laboratory conditions show that all the test indicators meet the design requirements.
