Intelligent temperature and humidity control device

Abstract

The invention discloses an intelligent temperature and humidity control device relating to a device capable of precisely controlling the temperature and the humidity of a vegetable greenhouse. The invention provides a device for intelligently controlling the temperature and the humidity of a vegetable greenhouse. The device comprises temperature sensors, a digitron display, an alarm, humidity sensors, a microprocessor and an output control system and has the structural key points that the temperature and the humidity of each position in a greenhouse are collected through the temperature sensors and the humidity sensors (at most 8 temperature and humidity sensors can be connected), the collected real-time temperature and humidity are displayed through a 4-bit digitron so that a vegetable grower knows about the environment situation in the greenhouse, and meanwhile, a control unit of a system determines whether to heat or open an air door according to the change situations of the temperature and the humidity. An alarm circuit alarms to prompt an agrotechnician of randomly inquiring a collection value and alarm information when the collected environment parameter value is larger than the set upper and lower limit values.

Description

Technical field: [0001] The invention relates to a temperature and humidity intelligent control device, in particular to a device capable of precisely controlling the temperature and humidity of vegetable greenhouses. Background technique: [0002] With the development of our country's national economy, people's living standards are improving day by day, and the vegetable market in winter greenhouses is expanding day by day. Especially in the cold winter in the northern region, only relying on the long-distance transportation of vegetables from the south to the north, not only the cost is high, but also the best time for vegetables is delayed. edible period. Therefore, relying on agricultural technology and vigorously promoting the cultivation of vegetables in plastic greenhouses is an inevitable development trend of vegetable cultivation. At present, most farmers still use the method of manual duty to take care of vegetable greenhouses, wasting a lot of manpower and materi...

Problems solved by technology

At present, most farmers still use the method of manual duty to take care of vegetable greenhouses, wasting a lot of manpower and material resources, and the temperature and humidity control of vegetable greenhouses is not ideal, often due to improper temperature and humidity control, crop yields are reduced, which brings vegetable farmers. great loss
