【摘要】：滑坡监测的重点是对滑坡体倾斜角变化的监测。针对目前滑坡监测仪器高精度、高可靠性、高自动化程度及高便携性的要求,提出了一种基于SCA100T和CC2530的无线滑坡监测系统。系统以STM32单片机作为主控MCU,采用SIM900模块实现GSM网络接入,基于9 V干电池,12 V、40 Ah蓄电池和小型太阳能发电系统完成系统持续供电;分为采集终端、采集站、接收主机3部分。采集站通过SCA100T传感器采集滑坡体倾角信息,各采集站和采集终端之间采用Zig Bee进行通信,采集站基于GSM网络将数据发送至远程的接收主机。系统程序设计采用主动上传与定时上传相结合的机制降低功耗,利用短信触发或定时器定时触发,驱动倾角传感器采集,并启动GSM模块实现远程自动化传输。该系统倾角监测绝对精度高达0.035°。
[Abstract]:The focus of landslide monitoring is to monitor the slope angle of landslide body. Aiming at the requirement of high precision, high reliability, high automation and high portability of landslide monitoring instruments, a wireless landslide monitoring system based on SCA100T and CC2530 is proposed. The system uses STM32 microcontroller as main control MCU, to realize GSM network access using SIM900 module, based on 9 V dry battery, 12 V 40 Ah battery and small solar power generation system to complete the system continuous power supply; It is divided into three parts: collecting terminal, collecting station and receiving host. The acquisition station collects the slope angle information through the SCA100T sensor, and communicates between the collection station and the acquisition terminal using Zig Bee. The acquisition station sends the data to the remote receiving host based on the GSM network. The system uses the mechanism of active upload and timing upload to reduce the power consumption, uses short message trigger or timer timing trigger, drives the obliquity sensor acquisition, and starts the GSM module to realize remote automatic transmission. The absolute accuracy of the system is as high as 0.035 掳.
