物运料场堆取料机无线通讯中断技术攻关

Tackle the key problems of wireless elecommunications of stacker-reclaimer in the stock ground

根据原料场及堆取料机的空间位置关系，采用无线传输代替有线传输，在系统维护成本和修复时间等方面，极好的解决了有线传输方式所面临的问题；在本系统中，采用的是STT900-H-SS20无线通讯系统。

Because of the lang distances between the stacker-relcaimers in the stock ground wireless telecommunications system（STT900-H-SS20） was adopted instead of none wireless equipments, eshalb the maintainess cost and duration reduced.
