Humiture center control instrument

Abstract

The present invention provides a central temperature and humidity control instrument, which respectively connects with an initial value keyboard setting module, an initial value voice setting module, a multifunction digital display module to display operating state of a plurality of paths, a LED temperature digital display module, a LED humidity digital display module, a data information voice broadcasting module, a multi-path data and command conversion and transmission module on each corresponding IO port with a SCM SPCE061A as an inner core. Wherein, the central temperature and humidity control instrument is connected with a plurality of temperature and humidity network node control instruments through a multi-path select electronic switch. In addition, the control instrument compares onsite temperature and humidity data information collected by the temperature and humidity network node control instrument with the set value and emits a control command to a corresponding temperature and humidity network node control instrument. The temperature and humidity network node control instrument controls a multifunction executor through program control to execute heating, refrigerating, humidifying, dehumidifying, air draft, air exchange and other intelligent control and utilize LED to display and broadcast relevant information through voice. The present invention is suitable for intelligent environmental condition management of large-scale agricultural breeding, vinyl house and green house.

Description

Technical field [0001] The invention relates to a control device for regulating temperature and humidity in greenhouses and greenhouses, in particular to a central temperature and humidity controller. Background technique [0002] In the greenhouses of modern agriculture and breeding, the control of heating, cooling, humidification, dehumidification or ventilation is generally controlled by a single-chip microcomputer. Its shortcoming is that the existing automatic control equipment usually can only realize one or several of the above-mentioned functions, and lacks the temperature and humidity central controller and network point controller that are mutually matched and independently produced, as well as a variety of Functionally integrated actuators, therefore, make it impossible for users to flexibly choose appropriate varieties and appropriate quantities of supporting devices for combination according to different control ranges and actual needs of the production environm...
