Abstract


Landslide is a major disaster, it is due to the slope rock mass affected by the earth's crust along the shear failure surface used to pass a slippage occurred. Frequent geological disasters in recent years due to industrial and agricultural production and even sent all the people's lives and property caused huge damage. Therefore, landslide monitoring and early warning systems to reduce such disasters has become an important technique in the national economy has a very important value. At present, the main methods of landslide monitoring simple observation pile method, simple observation of surface deformation, buildings tilt observation and so on. With the rapid development of technology, how to make use of new technology and methods landslide displacement monitoring more effective, more secure, more real-time, has become a new research focus. Therefore, this paper proposes a landslide based on GPS and GPRS monitoring system that will Global Positioning System with General Packet Radio Service effectively combined, for damage, deformation and obviously has a certain scale, real-time monitoring of landslide, this method improve the monitoring accuracy and achieve automatic collection of data. This study is done in landslide monitoring by understanding the background and development process of the premise, based on GPS and GPRS proposed design and working principle, which mainly include: (1) landslide monitoring subsystems: the first is the use of GPS Test displacement occurs, which uses a multi-point manner relative positioning improves positioning accuracy. Then the GPS satellite information received data transmitted to the main control system using microcontroller, the data processing. (2) Data transmission subsystems: the data transmission is divided into wired and wireless in two ways, given wired with wiring complexity, vulnerable to lightning, installation and maintenance costs are high, vulnerable to sabotage and other shortcomings, this project proposes a kind based on the GPRS network and the wireless transmission module SIM300C landslide monitoring system, basically solved the problem of data transmission. Then focus on the main control system hardware and software design in detail, hardware mainly includes: the main controller design (optional STM32F103 host microcontroller chip), power supply design SIM300C module design, interface design; software include: the use of TCP / IP protocol stack, data transmission, SIM300C and PC connection and computer for data processing and monitoring. Master control system to achieve a valid connection of each module, which make up the system overall program implementation. The system uses a modular design concept, which are relatively independent of each hardware to run, so you can more quickly and easily for system assembly, commissioning, can effectively reduce the actual development cycle. Finally, the full text paper summarizes the work carried out and the prospects for future work; provided in the appendix of the system hardware and circuit design. This article is mainly about in the wild environment monitoring terminal design, the emphasis on landslide monitoring system MCU control, and wireless data transmission.
