针对中小型卷烟厂使用的７０年代生产的烟机设备普遍都存在的故障率高、可靠性低、生产效率较低的问题，对ＨＬＰ１翻盖式硬盒小包机电气系统和调速系统进行了改良．用ＰＬＣ控制取代了传统的继电器、接触器逻辑电路，用变频调速取代了原有的励磁调速，变频调速的实现依赖于ＳＰＷＭ技术和大规模集成电路．实践检验，该设备改造后取得了预期的效果．
For the small and medium-sized cigarette factory used in the 70’s production of smoke machine equipment prevalence of high failure rate, low reliability, low productivity problems, HLP1 clamshell hard case packet charter electrical and speed system improvements . With PLC control to replace the traditional relay, contactor logic circuit, with the frequency control to replace the original excitation speed, frequency control depends on the realization of SPWM technology and large scale integrated circuits. Practice test, the equipment has achieved the desired results after transformation.
