【摘要】：随着农业温室大棚迅速推广和使用,适宜的农作物生长环境下的蔬菜、水果等使人们的生活水平有了明显提高。通过合理、适当地控制农业温室大棚环境因子如CO2浓度、温湿度、光照度等,对于农作物的生长至关重要。在众多的因子中,温度对农作物生长发育,新陈代谢、光合作用等都有着至关重要的影响。通过对杨凌示范区及周边和陕西部分地区调研、走访后发现,绝大多数的温室大棚种植户仍以家庭单个作业,依然采用传统温度计人工测温,人工操控设备,实时性差、精度低,费时、费力、效率低、投入成本较高。当前市场上的大棚综合因子测控系统因其价格高、操作维护复杂、性价比低,不易被推广到大范围的单个作业的温室大棚用户使用。为更好地实现对温室大棚环境温度有效测控,以适宜的生长环境提高农作物的产量和质量。本文先基于PROTEUS、Multisim仿真软件平台,设计仿真出了大棚温度测控系统,可自动监测大棚温度,超出预设温度范围时,能发出报警信号,同时能实现控制外接温度调控设备。最后实际制作出了温度测控系统,并进入农业大棚实际测试。通过进一步完善和改进,实现了成本低廉的、功能稳定的,较为高效的,满足家庭单个作业的农业温室大棚温度测控系统。该系统不仅可用于农业温室大棚温度监测,还可用于冷库、畜牧饲养等场合。
[Abstract]:With the rapid popularization and use of agricultural greenhouse, the living standard of people has been improved obviously because of the vegetables and fruits in the suitable crop growing environment. It is very important for the growth of crops to control the environmental factors such as CO2 concentration, temperature and humidity, illumination and so on. Among many factors, temperature plays an important role in crop growth, metabolism and photosynthesis. Through the investigation of Yang Ling demonstration area and its surrounding areas and parts of Shaanxi Province, it is found that most greenhouse growers still work individually at home, still use traditional thermometers to manually measure temperature, manual manipulation of equipment, and poor real time performance. Low precision, time-consuming, laborious, low efficiency, high input cost. Because of its high price, complex operation and maintenance, low performance-price ratio, the current greenhouse comprehensive factor measurement and control system in the market is not easy to be used by a large range of greenhouse users with a single operation. In order to realize the effective measurement and control of greenhouse environment temperature, the yield and quality of crops can be improved by suitable growing environment. In this paper, based on the proteus Multisim simulation software platform, the greenhouse temperature measurement and control system is designed and simulated. The system can automatically monitor the greenhouse temperature. When the temperature is beyond the preset temperature range, the alarm signal can be sent out, and the external temperature control equipment can be controlled at the same time. Finally, the temperature measurement and control system is made and tested in the agricultural greenhouse. Through further improvement and improvement, the temperature measurement and control system of agricultural greenhouse with low cost, stable function and high efficiency is realized. The system can be used not only for temperature monitoring in agricultural greenhouse, but also for cold storage and animal husbandry.
