摘要随着农业方面生产规模的提高，对于大规模且数目很多的大棚来说，老旧的温度控制方法就出现了比较大的局限性。所以，在现代化的大棚管理学中，加入了温度自动控制及监测系统，以适应现代化的生产需求。本论文主要叙述的是一种自行规划并设计的基于STC89C52单片机为主控制器的无线大棚温度监测系统的设计原理及软硬件的设计过程。这套设计体系我采用DS18B20温度传感器来采集温度信息、STC89C52单片机作为主机及从机的控制芯片、NRF2401无线通信模块负责主机与从机之间的信息传输、LCD1602液晶显示屏作为显示器来显示当前接收到的数据即大棚的实时温度信息。当大棚室内温度超过预设温度值时，系统会采取蜂鸣报警处理。这样的话就能使用户无需亲临大棚，只需要坐在控制室里，就可以实时知晓各大棚的温度，为管理大棚提供了便利。  31998

The design of wireless temperature monitoring system for greenhouse
ABSTRACT
With the improvement of agricultural production scale, the old temperature control method has been more limitations for the large scale and large amount of greenhouse.. So, in the modern greenhouse management, the temperature automatic control and monitoring system, in order to meet the production needs of the modernization. This paper mainly describes the design principle and the design of the hardware and software of the wireless greenhouse temperature monitoring system which is based on the STC89C52 single chip microcomputer. The design of this system I use temperature sensor DS18B20 to collect temperature information, STC89C52 microcontroller as the host and from the machine control chip, nRF2401 wireless communication module is responsible for the host and from between the machine and the information transmission, the LCD1602 LCD as the display to display the received data greenhouse temperature information in real-time. When the indoor temperature of the greenhouse exceeds the preset temperature, the system will take the alarm processing of the bee. Such words will be able to use the user without the need to visit the greenhouse, just sitting in the control room, you can know the temperature of the greenhouse, to provide a convenient management greenhouse.
