Based The Fpga Intelligent Greenhouse Monitoring And Control System Cpu Design And Implementation

With the constant breakthrough in greenhouse control technology, Intelligent greenhouse has become a new stage of development of greenhouse control. As a typical representative of agricultural facilities. How to achieve high efficiency of detection and control and operation of low cost is a major problem to be solved. For the current greenhouse Control System for the adjustment of greenhouse environmental factors is not accurate enough, the high cost of control system, and the popularization of rural issues. This text presents a dedicated CPU, It can offer good support for the intelligent control algorithm for hardware integration, therefore, the same expert knowledge can be responded without PC involvement and the support of huge expert database system in the hope of offering the hardware support for developing Intelligent Greenhouse measurement and control system with low costs.The Main Research task of this text is for Environmental Monitoring of Intelligent Greenhouse and needs of Control system, Designing and implementing a dedicatedly embedded CPU. Contents of the study include:1. Researching Controllers and Architecture of Greenhouse control system, and confirmed the System processor design and intelligent control algorithm, According to the demanding of intelligent greenhouse environment control system, meanwhile for Processor design and discuss.2. Research and learning the structure and function on normal CPU, analyze the characteristics of the CISC and RISC, decided to adopt the state machine Control Unit, avoiding complex microprogrammed control unit3.Offered 16-bit dedicated CPU architecture, design the appropriate instruction and using VHDL language Structured and realization of the CPU part of the function module (Comparator, registers and registers group, shift registers, ROMM Read only memory module and comparators) and Operation module (floating-point Adder, multiplier and divider), By QuatrusⅡenvironment with functional simulation validation4. Designing a dedicated CPU for the intelligent control system of greenhouse environments, take taking note of the general and specific features of the CPU and general CPU. For the features of greenhouse environment control, add Scalable the comparator group of environmental values. Each comparator's function is that a single environmental value is compared with the normal value and take measures to adjust in accordance with algorithm. This not only saves space for accessing to data, but also improves the efficiency of the greenhouse environmental monitoring system.5. In order to solve run offline Of Intelligent control methods, FPU is set in ALU Supporting hardware integration of intelligent control algorithm.
