摘要: 对目前矿用带式输送机输送量的测量方法即电子胶带秤测量法、核子胶带秤测量法、超声波测距测量法、激光CCD图像测量法、激光扫描测量法进行了分析，并从测量精度、响应时间等方面对各种方法进行了对比分析。接触式测量法中，电子胶带秤测量法测量精度高，但响应速度较慢，稳定性较差；非接触式测量法中，激光扫描测量法测量精度较高，响应速度较快，稳定性较好。指出带式输送机输送量测量方法的发展趋势是提高测量精度、抗干扰性和适应性，非接触式测量法或融合多种技术的方法将逐渐成为主流的输送量测量方法。Abstract: Measuring methods of current mine-used belt conveyor were analyzed, which are electronic belt scale measuring method, nuclear belt scale measuring method, ultrasonic ranging measuring method, laser CCD image measuring method and laser scanning measuring method. Various methods were compared and analyzed from aspects of measurement accuracy, response time,etc. In contact measuring methods, electronic belt scale measuring method has high measurement accuracy, but response speed is slow and stability is poor. In non-contact measuring methods, laser scanning measuring method has high measurement precision, high response speed and good stability. It is indicated that development trend of measuring methods of conveying capacity is to improve measurement accuracy, anti-interference and adaptability; non-contact measurement method or a method combining various technologies will gradually become the mainstream measuring methods of conveying capacity.
