②The installation of automated professional monitoring equipment is small, and some disaster points that have installed professional geological disaster monitoring equipment are all single-point monitoring, and the effective area of monitoring and control is small, and area disaster warning cannot be carried out;

③The current automatic monitoring equipment (surface displacement, deep displacement, rainfall) lacks on-site early warning function.

④ The currently widely used automatic rainfall collection equipment has a single type of access equipment and cannot complete the function of compound parameter early warning, which has a certain impact on the occurrence of geological disasters and early warning and avoidance work.

⑤The early warning mechanism is not direct. The current early warning process is basically: professionals regularly collect data on site (or automatic monitoring equipment sends data to the data center), and data analysts analyze the data after learning the monitoring data to reach the early warning threshold The early warning information will be sent to the responsible unit of the monitoring point, and then the responsible unit will issue the final early warning. This kind of early warning mechanism has many links and a long cycle, which seriously affects the timeliness of sudden geological disasters. In severe cases, it will miss the best time for emergency avoidance, causing heavy human and economic losses.
