智能农业大棚控制器的设计与实施
摘要 虽然社会经济在越来越快地增长，人民的生活水平也在迅速提升，但是，随之而来的人口剧增、环境恶化与资源紧张之间的矛盾也更显突出。伴随着社会经济的兴旺，科技的力量也越发强大。无线传感技术、计算机通信技术、嵌入式技术的兴起，农业大棚、家居等也在运用这些技术手段，形成了智能农业大棚、智能家居等。国内传统的农业大棚种植过程中，主要依靠人力和一些并不复杂的手工工具。农业种植的科技含量较低，装备水平相当落后，灌溉、光照和施肥等等的控制全都主要依靠人的主观判断，导致农业大棚的生产率并不比其他不用大棚的高，最终阻碍了科技在农业方面的进步，已经农业生产工具方面的创新。
国内研究智能农业大棚技术的步伐要落后于国外的发达国家。从开始研究到现在，肯定获得了一定的研究经验和成果，但是和国外比起来还是有差距的，这些差距主要体现在系统的完整性和稳定性两方面。本文通过研究 ZigBee 无线组网技术，交流对农作物的生长有比较重要影响的环境因素，讨论了基于CC2530单片机芯片的节点控制功能，剖析了农业大棚控制系统在各方面是否是能实现的。然后进行系统设计并且使该系统实现了。最终设备能够实现测量农业大棚内的温度、可燃气体现状，上传收集到的信息并且做出相应的处理。经测试，该系统运行状况良好，而且能够实现其应有的功能。

Intelligent Agriculture Greenhouse Controller
Abstract While the social economy is growing more and more quickly, people's living standard is also rapid ascension, however, the subsequent population, environmental degradation and the contradiction between resource is also more prominent. With the prosperity of social economy, the power of science and technology is also increasingly strong. Wireless sensor technology, computer communication technology, the rise of embedded technology, agricultural greenhouse, also in the use of these techniques such as household, formed the intelligent agricultural greenhouses, smart home, etc. Domestic traditional agricultural greenhouse planting process, rely mainly on human and some hand tools is not complicated. Agricultural science and technology content is low, equipment level is quite backward, irrigation, light and fertilization, and so on all depends largely on the control of man's subjective judgment, lead to the productivity of agriculture greenhouse no higher than the other don't shed, eventually hindered the progress of science and technology in agriculture, has the innovation of agricultural production tools.
The pace of the domestic research intelligent agricultural greenhouses technology to lag behind the developed countries abroad. From began to study now, must obtain a certain research experience and achievements, but compared with abroad still has a gap, the gap is mainly reflected in two aspects of system integrity and stability. This article through studies ZigBee wireless network technology, communication has more important influence on the growth of the crops of environmental factors, based on CC2530 microcontroller chip node control function is discussed, analyzed the agriculture greenhouse control system in all aspects can realize or not. Then carries on the system design and make the system has been realized. Eventually equipment can realize the measurement of temperature in the agricultural greenhouses, combustible gas, upload the collected information and make corresponding processing. After testing, the system is running in good condition, but also can realize its function.
