为了实现环境监测数据的有效采集与传输,设计了环境监测数据采集与传输系统。在B/S架构下设计系统总体结构,并在系统硬件部分设计上位机、A/D转换器与FPGA硬件接口电路以及环境监测传感器通信节点硬件。软件部分以上位机内的数据为基础,采用一致度计算的多源数据整合方法对采集的环境监测数据进行整合,并存储整合后的环境监测数据,以用于后续的传输。实验结果表明:该系统在长时间运行过程中自动热启动次数较少,运行较为稳定;通信传输时的频谱效率与理想频谱效率重合度较高,通信性能卓越。

In order to realize the effective collection and transmission of environmental monitoring data, an environmental monitoring data collection and transmission system is designed. The overall structure of the system is designed under the B/S architecture, and the upper computer, the hardware interface circuit between A/D converter and FPGA and the communication node hardware of environmental monitoring sensor are designed in the hardware part of the system. Based on the data in the upper computer, the software adopts the multi-source data integration method of consistency calculation to integrate the collected environmental monitoring data, and stores the integrated environmental monitoring data for subsequent transmission. The experimental results show that the system has less automatic hot start times during long-time operation, and the operation is relatively stable, the coincidence between the spectral efficiency and the ideal spectral efficiency during communication transmission is high, and the communication performance is excellent.
