【摘要】 中国是世界上最主要的农业大国，为了满足经济发展和人民生活水平的不断提高，必须保持农业的可持续发展；目前解决问题的关键是寻求高效农业，把高科技应用到农业上；采用先进的农业设施，应用先进的科学技术和管理技术。本文介绍了一种实用的农业环境信息采集管理系统，该系统由便携式环境参数测量仪、数据转存器和数据管理系统软件组成，系统以AT89C51单片机为核心，便携式环境参数测量仪应用先进的数字式传感器技术，检测技术和微型计算机技术系统，来实现对农田环境的温度、湿度、光照和雨量(预留)的检测，系统主要通过单片机的I／O口、定时器／计数器和外部中断来实现温度数值、湿度频率值和雨量数值的读取。系统主要由数据采集模块、数据存储模块、键盘扫描模块、输出显示模块和通讯模块组成，能定时完成环境参数的采集、存储、显示浏览等功能；数据转存器能完成将多台数据转存器的数据转存于计算机；数据管理系统软件能实现环境参数的显示、查询、统计和打印等功能。由于系统采用全数字传感器，抗干扰能力强，便于远距离传输，整个系统具有较高的性能价格比，操作简单，性能可靠，具有较强的实用性。更多还原

【Abstract】 China is the largest agriculture country It solves the food problem of twenty-two percent population with seven percent cultivate land of the world, but the contradiction between the increasing of population and decreasing of cultivate land, especially the world economics and social development is in a new period. In order to satisfy the development of economy and improve the level of people’s life, the agriculture must develop persistently. At present, the emphasis is to find efficient agriculture and apply the new technology to agriculture. With the development of computer technology and information, modem agriculture takes the place of tradition agriculture in production fashion. This paper introduces a utility data gathering system of agriculture environment messages. It gets the data of temperature, humidity, illumination and rainfall by I/O interface, timer and external interruption. The system consists of portable measuring instrument of environment parameters, data memory instrument and data management system. It uses AT89C51 single chip processor as the core. Portable measuring instrument uses advanced sensor technology, automatic measurement technology, communication technology and microcomputer technology to gather temperature, humidity, light intensity and rainfall (reserved). It contains such modules as data gathering, data memory, keyboard scanning, displaying output and communication module. It can gather, reserve, display, and scan the data at several time Data memory instrument can transfer the data from several portable measuring instruments to computer. Data management system can output look up statistic and print the data. It has the strong anti-disturbing capability, reliability and convenient for the data transmitting in long distance, because the system has the digital sensors. It is convenient to operate and high in the ratio of performance to price, so it has highly utility.更多还原
