摘要
开发了一种以计算机为平台的温室滴灌施肥控制系统,以实现对温室内不同地块间滴灌施肥量的控制。系统以计算机为核心,采用ATmega128单片机作为系统数据采集和处理的内核,以及Digmesa FM系列多液流式液体流量传感器对不同量的液体肥料进行控制,并以VC＋＋6.0作为上位软件开发工具,编制了人机交互界面友好的温室滴灌施肥量监视软件。对本系统进行的大量试验测试数据表明：本系统具有较高的控制精度,在0.5~18.00 L/min量程范围内最大误差为1.5%,满足精确施肥和精确灌溉的性能要求。
A computer-platform controlling system of drip irrigation in greenhouse was developed.Control drip irrigation fertilizing run off of the different plot in greenhouse was realized.The system used PC as core,used the ATmega128 single-chip as kernel of the system data acquisition and processing,and used Digmesa FM series liquid flow sensor to control different run off of liquid fertilizer.Greenhouse drip fertilizer surveillance software with interactive interface was developed based on VC＋＋6.0 platform.A higher controlling accuracy was indicated by a large number of experimental test,and the largest error was 1.5%in the range of 0.5-18.00 l/min,which can meet the requirements of the precise fertilization and the precise irrigation.
