The key point of landslide monitoring is monitoring the change of landslide's incline. According to such re-quirements as high measurement precision,high reliability,high degree of automation,high portability and low power consump-tion of the existing landslide monitoring system,a wireless landslide monitoring system based on SCA100T and CC2530 is pro-posed. The system chooses STM32 as the core MCU;GSM network is realized by using SIM900 module access;based on the 9V dry battery 12 V 40 Ah battery and small solar power systems to complete system for power supply;divided three classes:acqui-sition node,base station and receiving host. Acquisition node use SCA100T to get the angle information and acquisition node and base station constitute a wireless network based on ZigBee protocol. Base station send the information to the receiving host by GSM network. The system upload data actively or timing,using SMS or timer trigger to Drive the sensor and star GSM mod-ule to realize the automatic remote transmission. The system's angle precision reaches to 0. 035°.%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ZigBee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°.
