Design And Implementation Based On Single Chip Microcomputer Greenhouse Temperature And Humidity Remote Monitoring

Temperature and humidity is the industrial and agricultural production in commonand one of the most basic parameters, using modern technology to temperature andhumidity detection, digital display, information storage and real-time control, toimprove the agricultural production efficiency and product quality, energy conservationand so has an important role in. This thesis combines MCU, sensor, communication andcomputer technology to design a set of hardware and software of greenhousetemperature and humidity control system.System using single chip as the core, with a plurality of temperature, humiditysensor as a collection element, through the MCU and digital sensor, sensormeasurement data acquisition and storage. SCM acquisition and processing the datathrough RS-232transmitted to the computer, the computer will chip transmission ofdata storage, record and alarm, for the staff to browse, records and associated processing.Another, but also the realization of monitoring and control system of single-chipdevelopment function, real-time data display, alarm and data storage function.This thesis mainly completed the following aspects: determining the overall designscheme of the system. Including the principle of the system design, complete the designcontent, the proposed technology route and the entire system software and hardwarecomponents. The greenhouse environmental data collected at multiple points in design.Includes digital temperature and humidity sensor monitoring time series, principle ofmonitoring, monitoring circuit and monitoring system software design. The wirelessnetwork communication and alarm design. Including transfinite alarm data transmission,GSM network protocol model, the short message module transmission principle,wireless transmission of TC35hardware and software design. Finally the whole systemfunction testing, to achieve the expected goal.This system will MCU, sensor, communication and computer technology, thesensor point collection and GSM wireless transmission combination method, putforward a kind of feasible greenhouse monitoring system. The system can becomprehensive, real-time, automatically monitoring data storage, processing and recording, and according to the actual situation, timely processing. Implementation oftemperature and humidity in the greenhouse environment monitoring, achievetemperature and humidity monitoring automation and intelligent.
