发送单元 meaning in Chinese

transmitting element

But there has been not correspondingly control system for it by far . ln this thesis a pulse nitrogenous conveying control system based on profibus is designed and achieved on the thinking of modularizing the pulse nitrogenous conveying system , which can be used for different the pulse nitrogenous conveying system and added new control cells . the thesis reviewed systematically the pulse nitrogenous conveying system in practical , and makes the understanding that the system is composed of standard gas storage cell , conveying equipment cell and target container ceil . then a common modularized control system project is designed and achieved by structurized programming orienting process , which consists of four control models , respectively for gas storage cell , for conveying equipment cell and for target container cell
本文综合实际使用的氮保护脉冲气力输送系统，把氮保护脉冲气力输送系统分为标准化的气源设备单元、发送设备单元和目的料仓设备单元，在此基础上，设计了用于氮保护脉冲气力输送系统的通用模块化控制方案，采用面向过程的结构化编程思想，基于profibus现场总线，实现了组成该方案的四类控制模块：气源单元控制模块、发送单元控制模块、目的料仓单元控制模块和通讯处理控制模块。
