Design of Plant Growth Cabinet Control System Based on LabVIEW

Abstract

For urban land resources are increasingly strained reality, the use of artificial controllable LED lights and virtual instrument technology, simulation of plant growth in natural environment as possible.This system of artificial plant growth platform controlled environment, focusing on the virtual instrument technology in plant growth cabinet measurement and control system, using virtual instrument software platform LabVIEW, a combination of hardware NI-PCI data acquisition card, using data acquisition (DAQ) technology, serial communication technology (VISA), digital I/O port technology to build software control platform, upload sensor data in real time via the data acquisition to the host computer, the host are displayed in real-time graphical interface to design and control of plant growth cabinet system that can achieve a controlled environment plant growth platform. Introduction With the development of the city, land resources are increasingly scarce, while in traditional plant cultivation, the land is an important integral part of the reality in this case, making it possible to artificial indoor cultivation of plants (such as flowers cultivation). With the rapid development of integrated circuits and computer communication technologies, virtual instrumentation technology emerges. Virtual instrument technology and control technology and computer technology is the product of combining powerful resource that makes use of computer hardware and software, reduce system cost, enhance system flexibility; usually more, in the form of lower machine composed of virtual instrumentation and control automation systems, which PC is usually composed by the PC, to achieve control of the lower machine and complete analysis of the data storage display functions; lower computer from the data acquisition circuit, data communication between the upper and lower machine commonly used RS-232C serial communication [1]. The overall design of the system platform The system is based on NI (National Instruments) company's PCI-6014 data acquisition card and LabVIEW software platform, developed by plant growth control system, along with the rapid development of virtual instrument technology, can well meet the system requirements for achieving collection that plant growth and control system development becomes easy and efficient. LabVIEW as a means of virtual panel user interface and a block diagram of the establishment of a virtual instrument graphics programming, has been widely applied to industry, academia and research laboratories and other areas, it is regarded as a standard data acquisition and instrument control software instruments [2]. The system is based on LabVIEW software platform and PCI data acquisition cards that developed for plant growth cabinet and control system, including data acquisition, serial communication, data storage and other functions, to achieve dynamic monitoring plant growth inside the various environmental parameters.
