由于现代工业生产线越来越精密，分工越来越精细，一个环节的故障或生产速度

由于现代工业生产线越来越精密，分工越来越精细，一个环节的故障或生产速度的下降，将影响其下游工序的进行并造成极大的损失，因此，当故障发生时，如何能迅速找到维修人员，一直困扰着生产管理者。采用的对讲机、电话等手段也由于功能的限制而不能满足需要，电话是点对点通讯，操作复杂，接驳时间长等缺点，而对讲机由于信号和通讯信道的限制，不适合在一个特定场所大量使用。

As a result of modern industry production line more and more sophisticated, division of labor is increasingly sophisticated, a link failure or production rate decline, will affect the downstream process and cause great loss, therefore, when fault occurs, how to quickly find repair personnel, has been plagued by production manager.Using radio, telephone and other means are due to functional constraints can not meet the need, the telephone is the point to point communication, complex operation, the long time, while the interphone because the signal and communication channel restrictions, does not fit in a particular place heavy use.
