本系统是针对铁铬盐生产过程中主要技术指标含水量难以控制的实际问题而提出的。该系统采用单片机8097BH作为主控制器，在硬件设计上前后向通道均采用了变压器或光电隔离。在软件设计上采用模糊控制算法，使产品含水量能稳定在设定值范围内。
The system is proposed for the practical problems that the main technical indicators of iron, chromium salt production difficult to control the water content. The system uses single-chip microcomputer 8097BH as the main controller, in the hardware design forward and backward channels are used transformers or optical isolation. In the software design using fuzzy control algorithm, the product moisture content can be stabilized in the set value range.
