[Abstract]:With the rapid development of agricultural modernization in recent years, there is an urgent need for a kind of agricultural microclimate data acquisition system, which is suitable for low cost, low power consumption, wide popularization, stable performance and easy operation. To improve the understanding of the relationship between microclimate parameters and crop growth. However, the related research in our country started relatively late, and the related products in the market generally have some problems, such as insufficient comprehensive function, high cost, large power consumption, specialized operation, poor general-purpose and expansion ability of sensors, and so on. The purpose of this portable agricultural microclimate data acquisition system is to solve these problems centrally and powerfully. After researching and analyzing the related literature and existing research results, this paper first defines the goal, content and technical route of this research, that is, combining with Internet of things technology, Bluetooth technology on the basis of Android mobile phone. Sensor technology, information acquisition technology and so on, to achieve a set of low-cost, low-power, easy to operate and humanized portable agricultural microclimate data acquisition system; Secondly, this paper studies the Android platform, Bluetooth, sensors and other related technologies, and through the self-developed sensors with the flexible use of energy-saving technology to solve the problem of high cost and high power consumption of the existing products in the market. The hardware circuit of the system is studied and designed again. These hardware is mainly composed of various sensors, MCU, serial port circuit, power supply circuit, system power source detection circuit, energy saving circuit design, external port design, protection circuit and so on. The parameters and characteristics of the sensor are introduced in detail. Finally, the software of the system and the protocol frame used in the system are designed and perfected. The software of the system mainly includes the design and development of the data acquisition terminal software and the mobile phone terminal APP. The communication protocol includes the formulation of protocol format and the design of related instructions. The system has been put into use in Guizhou tea field. The results show that the system is stable in performance, low in power consumption, low in cost, simple in operation and easy to expand.
