基于GPRS通信的地表径流泥沙在线监测系统设计

Design of online monitoring system for surface runoff and sediment based on GPRS communication

基于目前地表径流所产生泥沙的在线监测效率与检测准确率低的情况,基于GPRS通信开发了地表径流泥沙在线监测系统。该系统设计分为硬件与软件两部分环境,硬件环境主要设计了采集器、控制器、传输器和监测器四大模块;软件环境针对GPRS通信技术的特点,设计了系统在线监测流程。通过二者的结合与实际应用场景的分析得出,该系统径流泥沙含量数据值与实际值仅相差0.2 kg/m^(3),且数据较为稳定,由此可知该系统具有更高的时效性与稳定性。

Based on the current situation of low efficiency and poor detection accuracy of online monitoring of sediment generated by surface runoff,an online monitoring system of surface runoff and sediment is developed based on GPRS communication.The design of the system is divided into two parts:hardware and software.The hardware environment mainly includes four modules:collector,controller,transmitter and monitor;According to the characteristics of GPRS communication technology,the software environment designs the system online monitoring process.Through the combination of the two and the analysis of practical application scenarios,it is concluded that the data value of runoff sediment content of the system is only 0.2 kg/m^(3) different from the actual value,and the data is relatively stable.Therefore,it can be seen that the system has higher timeliness and stability.
