In the prevention of geological disasters such as landslides，collapses and debris flows，especially in the soil and water conservation of major national electric power projects and water conservancy projects，various detection technologies have emerged at the historic moment，while traditional methods can not meet the real-time requirements.The development of computer technology and wireless communication technology and 3S technology have provided timely and rapid access to real-time detection data for analysis and treatment of geological disasters.This paper takes the Quaternary overburden slope landslide in Jiangxi province as the research object，designs a geological hazard monitoring and early warning system based on wireless communication，which integrates various innovative detection technologies and realizes its unique monitoring and early warning platform.It has a wide range of practical value.
