摘要
工业控制中 ,需要实时、无差错地传送一些数据 ,但工业生产环境复杂 ,有时无法采用有线方式进行传送 ,而无线数据传输必须考虑恶劣的电磁干扰。本文介绍一种采用直接系列扩频通信技术传送数据的方法 ,有效的抑制了无线干扰 ,在某大型钢铁公司投入使用半年来 。
In industry controlling, it is necessary to transmit data timely and without error. However, the circumstance in factory is complicated, it is difficult to achieve that with cable. One has to think about the electromagnetic interference while using wireless means. It proposes a measure to transmit data by using DSSS technique in this paper. The system has been working well for half an year in a hugeironsteel group.
