在蔬菜营养液膜栽培中,利用 PC—1500袖珍计算机价格低廉、稳定性好、耗电少、对电源无特殊要求、抗干扰性能好的特点,并自制接口与外围设备构成数据采集、监测、记录和调整的闭环控制系统,完成预定的设计要求。在软件上采用 BASIC 语言与汇编语言混编,操作者很容易掌握和调整,为我国现阶段在营养液膜栽培中推广使用计算机控制,完善实用化的营养液膜栽培技术,探索出一条可行路子。
In the vegetable nutrition liquid film cultivation, the use of PC-1500 pocket computer low cost, good stability, low power consumption, no special requirements on the power supply, anti-jamming performance is good, and self-made interface and peripheral devices constitute data collection, monitoring, Record and adjust the closed-loop control system to complete the predetermined design requirements. In the software using BASIC language and assembly language compilation, the operator is easy to grasp and adjust for the current stage in our country to promote the use of computer-controlled cultivation of liquid nutrition, improve and practical nutrition liquid film cultivation techniques to explore a viable way .
