摘　　要：周期检定对电子皮带秤的准确性有很大的作用,但不能从根本上解决皮带秤在检定周期内所产生的失准问题。采用建立数学模型实现简易在线实物校验,可以有效地预防或发现测量设备在周期内所产生的故障,不需另外增加设备投资,可实现实物校验,并可适应各种环境;电子皮带秤有诸多误差源,现场的维护、校准,是减少皮带秤“误差”的有效途径。电子皮带秤的维护性定期校验工作,尤其重要,须长期坚持。为解决皮带秤的在线校验难题,需寻求和采用新的技术和管理方法。Periodic verification plays an important role in the accuracy of electronic belt scale,but it can’t fundamentally solve the problem of inaccuracy in the verification period.Using mathematical model to realize simple on-line physical verification can effectively prevent or find the fault of measuring equipment in the cycle,without additional equipment investment,it can realize physical verification and adapt to various environments.There are many error sources in the electronic belt scale.The maintenance and calibration on site is an effective way to reduce the"error"of the belt scale.The maintenance and regular calibration of electronic belt weigher is particularly important and should be persisted for a long time.In order to solve the problem of on-line calibration of belt scale,new technology and management methods should be sought and adopted.
