温室环境参数测控仪的设计

Design and Study on Measuring-Controlling Instrument in Conservatory

介绍以AT89C52单片机为核心的温室生态参数测控仪的软硬件设计。该测控仪对测控参数(空气温湿度和土壤水分)采用V/F转换,由单片机实现测控,并通过X25045实现智能化标定与校准,可方便与PC机通讯,使该测控仪具有适应能力强、接口简单、抗干扰性能好以及适合远距离传输等特点,有利于提高测量精度,控制可靠,便于集中管理。

In the paper, the design on the hardware and software of the automatic measuring and colltrolling device for facilities agriculture is presented. Its controlling center is based on the Micro-controller AT89C52. The device measures the air temperature and humidity, the soil temperature and moisture Content by the V/F converter. It can not only realize the automatic and intelligent orientation and calibration by X25045 ,but also be in communication with PC. By selecting the sensors which are credible, cheap and satisfactory to the degree of the accuracy, the device can be applied extensively in the agriculture, thus the device has such features： the stronger adapt ion to the environment, the simpler interface, the stronger noise proof feature, the more distant transmission, the more measurement accuracy and the more controlling crudity. The device can be applied extensively in the facilities agriculture.
