Geological disasters are characterized by complex induction factors, poor predictability, sudden occurrence and the like, and in general, weak deformation is not easy to perceive and collapse time caused by the weak deformation is sudden. Under the condition, the real-time monitoring of the hidden danger points of the geological disasters such as landslides and the like is needed through precise monitoring equipment, and the change trend of the hidden danger points is predicted. At present, the main domestic monitoring method needs to solve the problems of power supply, network, wind prevention and the like, the cost is high, and the real-time monitoring coverage of geological disasters is generally limited by the problems of cost, network, power supply and the like, so that the method cannot be comprehensively spread. With the emerging NB-IoT in many LPWAN technology standards, it has the following advantages: 1. when the ultra-low power consumption equipment is in communication connection with a network, the battery power consumption of the equipment is low due to the fact that the transmission quantity is small, the frequency is low, the equipment is in a sleep state at ordinary times and the like, the battery can be enabled to supply power for more than 10 years continuously, and the long-term maintenance-free requirement is met. 2. The wide coverage and the deep coverage meet the requirements of a network, the connection coverage range of a single base station can reach dozens of kilometers, better signal penetration can be realized in severe environment through coverage enhancement, signals can enter the ground from the top to the bottom, and the problem of signal coverage blind areas can be basically solved. 3. The equipment connection capacity of a single base station with ultra-large connection capacity reaches tens of thousands or even hundreds of thousands, and compared with the traditional cellular network, the connection capacity is greatly improved, and the requirement of interconnection of everything can be effectively supported. 4. The low-cost low bandwidth, on one hand, the simplified design of the terminal device chip, makes the whole cost of the device built-in based on LPWAN standard communication module reduce, on the other hand, the low flow charge paid to the network operator by the application party caused by the small amount and low frequency of data transmission. Therefore, the NB-IOT enables deployment of a large number of geological disaster environment monitoring sensing devices.

If the safety state of the hidden danger points of the geological disaster can be monitored in real time, the hidden danger can be found in time, early warning is carried out in time, and disposal is carried out in time through the sensing monitoring equipment arranged at the key position, so that the situation that the landslide collapses, sinks and collapses and other dangerous situations can be effectively prevented without rain, and the property safety of the whole personnel can be guaranteed.

The monitoring of the safety state of the hidden danger points of the geological disaster has the important reason that the cost is too high, the equipment cost is high, the laying cost is high, and the operation and maintenance cost is high.

It should be technically feasible to apply NB-IoT technology to the security monitoring of geological disaster hazards.
