The Key Technology Design of the Real-Time Monitoring System Based on FPGA

Abstract

<p class="keywords"><span lang="EN-US">Due to having a direct affect for the growth of crops, the monitor and modification for the indicators of Greenhouse environment play significant roles in improving the yield of crops. The system, which adopts FPGA technology to control and modify the air condition and lighting system by collecting and analyzing the data of the temperature and humidity, has achieved good effects in practice. In our study, the key technology of real-time data acquisition system based on FPGA is proposed. In particular, based on FPGA, the designed ADC0809 and asynchronous FIFO can save the data in real time, which can be analyzed and disposed timely, so that the environment can be corrected in time.</span></p>

Design of an integrated A/D converter for dissolved oxygen sensor interface in aquaculture

“…Therefore, the selection of A/D converter chips needs to be considered in a comprehensive manner to choose the optimal solution. Here are examples of three A/D converter chips (ADC0809, AD7705, HX710A), comparing them in terms of A/D bits, conversion rate, power consumption and price [8][9][10]. Their comparison table is shown in Table 2.…”
