This network has some advantages with equipment with mixed protocol communications 这样的网络(单主机协议网络)比起混合协议通讯来说,具有某些优势。
Thirdly , according to the working principles of serial peripheral interface spi , it ' s advanced that the data communication of master - slave can be achieved through the i / o interfaces between modules by way of the software ' s following the spi model , thus solving the problem of integrated system 进而根据同步串行接口spi的工作原理,本文提出了通过模块间的i o口连接,用软件模拟spi模式,实现单主机多从机的数据通信,从而方便地解决了仪表系统的集成问题。
When cooling load is less than ice - melting ability , optimal control strategy is just ice priority , optimal control saves 24 - 45 % operating cost compared with chiller - priority . when cooling load is more than ice - melting ability but still less than ice - melting ability plus half of chiller cooling ability , optimal control is to keep chiller load to half of chiller cooling ability and tune ice - melting to meet load , optimal control consumes 13 - 20 % more power but saves 9 . 2 - 11 % operating cost compared with chiller - priority . when cooling load is more than ice - melting ability plus half of chiller cooling ability , optimal control is just ice - priority again , optimal control is to keep ice - melting to maximum and tune chiller to meet load , optimal control consumes 0 - 13 % more power but saves 0 - 9 . 2 % operating cost compared with chiller - priority 在冷负荷大于融冰供冷最大功率时,又分两种情况:总冷负荷小于融冰供冷最大功率加一半的单主机满负荷时,优化控制是保持主机供冷负荷系数为0 . 5 ,通过调节融冰来改变冷负荷,此时与主机优先比较增加能耗13一20 % ,节约运行费达9 . 2一11 % ;在冷负荷大于融冰供冷最大功率加一半的单主机满负荷时,优化控制就是融冰优先,通过蓄冰槽满负荷运行,调节制冷主机来调节冷负荷,此时比主机优先控制仅增加能耗o一13 % ,但能节约运行费o一9 . 2 % 。
