            01 查询状态指令	需要主控板定时发送查询指令，解析制冰机自检后回复的状态信息，以判断是否可以出冰。
            02 出冰指令	若制冰机状态为等待出冰，此时主控板可以发送出冰指令，以实现定量冰块输出。
            03 结束出冰指令	制冰机出冰过程中，由主控板按一定的时间发送结束指令折算时间所对应的冰量
            04 待机指令	当制冰机处于工作时，发送该指令使制冰机处于待机状态
            05 开机指令	当制冰机处于待机时，发送该指令使制冰机，制满一桶冰。
            06 抽水请求指令	预留抽水请求指令
            07 版本查询指令	品牌+硬件版本+软件版本
            09 冰量控制	通过定时开关方式控制制冰机出冰量
