[Abstract]:Temperature and humidity is one of the most common and basic parameters in industrial and agricultural production. The use of modern technology for temperature and humidity detection, digital display, information storage and real-time control can improve the efficiency of industrial and agricultural production and the quality of products. Energy conservation plays an important role. This paper designs a hardware and software greenhouse temperature and humidity monitoring system combined with single chip microcomputer, sensor, communication and computer technology. The system takes single chip computer as the core, takes a number of temperature and humidity sensors as the acquisition element, and connects the single chip computer to the digital sensor to collect and store the measurement data of the sensor. The data collected and processed by single chip computer are transmitted to computer through RS-232. The data transmitted by single chip computer are stored, recorded and alerted, which can be browsed, recorded and processed by the staff. In addition, MCU also realizes function expansion of monitoring system, real-time display of data, over-limit alarm and data storage. This paper mainly completes the following aspects of work: 1 to determine the overall design of the system. It includes the system design principle, the completed design content, the technical route to be adopted and the software and hardware of the whole system. 2. The multi-point collection design of greenhouse environmental data is made up of the software and hardware of the whole system. Including digital temperature and humidity sensor monitoring timing, monitoring principle, monitoring circuit and monitoring system software design .3 wireless network communication and alarm design. Including the transmission of over-limit alarm data TC35 network protocol model, short message module transmission principle, wireless transmission module TC35 hardware and software design. Finally, the function of the whole system is tested and the expected purpose is achieved. This system combines single chip microcomputer, sensor, communication and computer technology, adopts the method of sensor multi-point acquisition and GSM wireless transmission, and puts forward a feasible greenhouse monitoring system. The system can store, process and record the monitoring data in a comprehensive, real-time and automatic manner, and deal with the monitoring data in time according to the actual situation in the field. The remote real-time monitoring of temperature and humidity in greenhouse is realized, and the automation and intelligence of temperature and humidity monitoring are realized.
