摘要
生物大棚环境测控,即根据植物生长发育的需要,调节生物大棚内环境条件的总称。进行环境测控是实现温室生产管理自动化,科学化的基本保证,通过对监控数据的分析,结合作物生长发育规律,控制环境条件,使作物在不适应生长发育的反季节中,可获得比室外生长更优的环境条件,达到作物高产的栽培目的。
我国从国外引进的一些环境监控设备,由于其测控的侧重点与我国气候条件不相匹配,且引进价格昂贵,运行费用高,一次难于在我国大规模推广和应用。目前,国内自行设计,自行建造的智能生物大棚,大部分测控水平较低,现代化管理水平不高,不能够满足作物全年高产栽培的要求。因此改变传统的测控方式,实现计算机测控,建立符合我国国情的智能生物大棚,对加快我国温室生产的现代化水平及提高温室的经济效益均具有重要意义。
因此在分析了生物大棚的环境参数,综合测控特性,以及测控过程的非线性、大滞后的复杂过程后,综合运用传感器技术,gprs技术等,自行研究和设计了一个实用的生物大棚环境测控系统,可以实现对生物大棚中CO2浓度,温度,湿度等的测控。
鉴于上述情况,本文提出的生物大棚环境测控系统采用了多传感器技术和控制系统相结合的测控方案。其中,多传感器的管理和融合系统更能完善、准确的反映环境特征,以获得最高的检测精度和可靠的控制决策,使系统处于最佳运行。控制系统通过检测的环境参数来改变环境参数,使作物生长在最适宜的环境条件下。整个系统效率高且容易扩展,通用性和适用性较强。

ABSTRACT
Environmental monitoring and control of biological shed that, according to the needs of plant growth and development, regulation of biological greenhouse environmental conditions in general. Environmental monitoring is to achieve greenhouse production and management automation, the basic guarantee of the scientific, through the analysis of monitoring data, combined with crop growth and development of, control of environmental conditions in which growth and development of crops suited to the off-season, the availability of growth than the outdoor better environmental conditions, to achieve high yield crops, cultivation purposes.
China imported from abroad, some of the environmental monitoring equipment, because of its focus and the monitoring of climatic conditions do not match, and the introduction of expensive, high running costs, a difficult large-scale promotion and application in China. At present, their own design, the construction of intelligent life greenhouses, most of the low level monitoring and control, modern management level is not high, can not meet the requirements of crop yield cultivation throughout the year.
Therefore, monitoring changes in the traditional way to achieve computer control, and establishing greenhouse intelligent life situation of our country, to accelerate the modernization of the level of greenhouse production and improve the economic benefits of the greenhouse are of great significance.
Therefore, the analysis of biological environmental parameters greenhouses, integrated monitoring and control features, and process measurement and control of nonlinear, large delay in the complex process, the integrated use of sensor technology, gprs technology, self-study and design of a practical environmental monitoring and control of biological greenhouse system, can achieve the CO2 concentration of biological greenhouse, temperature, humidity measurement and control.
Given the above, the proposed bio-greenhouse environment control system using multi-sensor technology and control systems combining monitoring and
