介绍了一种基于微波技术的锅炉燃煤检测装置，详细阐述了采用微波技术进行锅炉燃煤检测的基本原理和装置的设计思路以及装置的硬件构成和软件实现。该装置与现有的该类产品不同，采用了“双参数”测量方法，即同时检测微波多普勒频移信号的强度值和频移值，从而可用于测量流速不恒定的过程物料流量。该装置以８０９８单片机为核心，具有信号采集、数据处理、瞬时／累计流量显示、高／低限报警等功能。
This paper introduces a boiler-burning coal testing device based on microwave technology, and elaborates on the basic principle of using coal-fired boiler technology to detect coal-fired boiler and the design idea of the device as well as the hardware configuration and software implementation of the device. Different from existing products, this device adopts the “two parameters” measurement method, which detects the intensity value and the frequency shift value of the microwave Doppler shift signal at the same time, and can be used to measure the process material flow with a non-constant flow rate. The device to the 8098 microcontroller as the core, with signal acquisition, data processing, instantaneous / total flow display, high / low limit alarm and other functions.
