中文摘要:
      针对堤坝远程监测有线传输方式信号失真、后期维护不便,以及部分无线通信技术开发难度大、成本高等问题,利用传感器多节点测量,结合RS485有线传输、2.4 G无线组网和GPRS网络,提出一种低成本、低功耗、易于开发的数据远程无线传输方案,实现高精度、大范围、全天候的堤坝边坡自动化监测。经测试,系统精度高、抗干扰性强,保持同一状态倾角传感器测量相对误差小于0.2%,温度传感器满足±3 ℃的精确度,湿度传感器满足±3%RH的测量精度,测试过程中无线组网稳定、远程数据传输可靠,监测界面直观明了。该系统在堤坝边坡稳定性和边坡防护检测方面具有实用价值。
英文摘要:
      Aiming at the problem of signal distortion and late maintenance of wired transmission in remote monitoring of dykes, some problems such as difficulty in developing wireless communication technology and high cost. By using sensor multi node measurement combined with RS485 wired transmission, 2.4 G wireless networking and GPRS network. A low cost, low power, easy to develop data remote radio transmission scheme is put forward,the system can realize high precision , large scale and all weather dam slope automatic monitoring. After testing, the system has high accuracy, strong anti interference, remaining in the same state angle sensor to measure, and the relative error is less than 0.2%. It also has a good linearity between -30° and +30°. The temperature sensor can meet the accuracy of ±5 ℃,and the humidity sensor can meet the precision of +3%.During the testing process, the wireless network is stable and the remote data transmission is reliable, and the monitoring interface is intuitive and clear.The system has practical value in dam slope stability and slope protection detection.
