摘　　要：系统以ARM LPC2378和无线射频模块为核心,分为上位机和下位机两部分。下位机作为数据采集模块,并连接执行装置和各类传感器,通过传感器采集农林环境数据,以一定时间间隔将各数据通过无线射频模块nRF905发送给上位机;上位机负责农林环境的监控,通过nRF905进行农林环境数据采集,并分析数据。当数据异常时,上位机发送执行信号给下位机,控制执行单元工作,从而改善农林环境,利于植物生长。整个系统实现了无线通信在数据采集及控制中的使用,传输距离较远,在生态环境监测领域具有广泛的应用。ARM LPC2378 and wireless radio frequency module are taken as the core of the system,and divided into two parts,master PC and slave PC. The slave PC is used as the data acquisition module and connected with the executive device and various sensors to collect agriculture and forestry environment data through sensors,and send each data to the master PC through radio frequency module nRF905 at a certain time interval. The master PC is responsible for agriculture and forestry envi-ronmental monitoring,execute agriculture and forestry environment data acquisition through the nRF905,and analyze data. When the data is unusual,the master PC sent an executive signal to the slave PC to control execution unit. The system can im-prove agriculture and forestry environment for the growth of plants. The system can realize the application of wireless communica-tion in the data acquisition and control. Its transmission distance is far. It has widely application in the field of ecological envi-ronmental monitoring.
