Abstract

Provided is an agricultural greenhouse temperature and humidity monitoring system based on a single-chip microcomputer and a programmable logic controller (PLC). The agricultural greenhouse temperature and humidity monitoring system based on the single-chip microcomputer and the PLC comprises a temperature and humidity sensor of each site, sub-site single-chip microcomputers, a main-site single-chip microcomputer, a controller PLC and a touch screen. Signals which is collected by the temperature and humidity sensor of each site are transmitted to each sub-site single-chip microcomputer through processing of a waveshaping amplifying circuit, data are optimized and processed through each sub-site single-chip microcomputer and then are input to the main-site single-chip microcomputer, the data are transmitted to the controller PLC through the main-site single-chip microcomputer, an order is issued to a blower controller, a temperature and humidity control device and the touch screen of the greenhouse through the controller PLC. The agricultural greenhouse temperature and humidity monitoring system based on the single-chip microcomputer and the PLC has the advantages that the temperature and humidity inside the agricultural greenhouse can be monitored and controlled, and meanwhile, real-time parameters of the current temperature and humidity can be displayed through a human-computer interface TP177B, so that environment of the agricultural greenhouse can be effectively improved to greatly promote crop growth.

Description

Agricultural greenhouse temperature, humidity control system based on single-chip microcomputer and PLC
