System for controlling temperature and humidity in greenhouse

Abstract

The invention relates to a system for controlling temperature and humidity in a greenhouse and belongs to the technical field of agriculture and aims to solve the problem that the temperature and humidity in the greenhouse of the northeastern region of China are hard to well collect and control in cold weather in winter, relieve the economic burden and labor of farmers, overcome the defects that traditional heat supply manners generate environment pollution and the like, and efficiently and intelligently regulate and control the temperature and humidity inside the greenhouse. The system comprises a thermal insulation part, a heating part and an indoor temperature and humidity control part. The indoor temperature and humidity control part comprises an xs128 minimum system, a keyboard module, a 12864 screen display module, a zigbee module, a temperature sensor module, a temperature and humidity sensor module and a pwm output module. The whole system is stable and reliable, simple in principle, and applicable to other related production equipment.

Description

technical field [0001] The invention belongs to the field of agricultural technology. Background technique [0002] With the development of reform and opening up, the degree of modernization in our country has been continuously improved. As a country with a large population in the world, various resources related to agricultural production are relatively small. As of 2009, my country's per capita cultivated land area was 1.39 mu, which was only 37% of the world average (3.75 mu per capita); per capita water resources It is 2,200 cubic meters, less than 1 / 4 of the world average, and is one of the 13 countries with the poorest resources per capita in the world. In the next few decades, my country's population will continue to grow, and how to solve the sharp contradiction of using less resources to feed a larger population is of strategic significance. Therefore, more and more attention is paid to agricultural research and application in our country, and the development of ag...
