摘　　要：目的:解决小量程下电子皮带秤核查方法效率低、精度低、安全性不高等问题。方法:设计一种用于小量程下电子皮带秤在线期间核查的装置,装置由数字化传输控制模块和自动加载模块组成。以标准码块作为输入量,工作时由上位机远程控制机械手,在传输带上实现码块循环取放加载,完成后由上位机对测量结果进行评定,并将核查评定结果上传至云端存储。结果:电子皮带秤在1440,3600 kg/h两个流量节点,能够保证核查加载精度在±0.5%的误差范围内波动,加载过程平稳均匀,远程控制稳定,单次核查试验耗时约3 min,约为传统方式的1/3。结论:该装置核查数据的在线存储、下载与上传稳定,能够对核查结果进行实时监测和预警。Objective:In order to prevent the problem of small range electronic belt scale with inefficient method of traditional intermediate verification,low verification accuracy and security.Methods:A on-line intermediate check device was designed for small range electronic belt scale,which was composed of digital transmission control module and automatic loading module.Taking standard weight as input quantity,the upper computer controlled the manipulator to grab the weight onto the transmission belt to implement cyclic loading,then evaluated the measurement results and upload the evaluation results to the cloud.Results:After verification test and data analysis,for electronic belt weigher,it could ensure that the checking loading accuracy fluctuates within±0.5%of the error range at two flow nodes of 1440 kg/h and 3600 kg/h.The remote control and loading process were stable,single verification test took about 3 minutes which was only one third of that of traditional methods.Conclusion:The download and upload of verification data are stable,cloud can monitor and warn the verification results in real time.
