A high-precision GNSS positioning method generally distributes measurement stations evenly in the range of a slope, and then carries out positioning comparison with a base station to obtain the displacement condition of the measurement stations. Because high accuracy GNSS location module belongs to the product that technical content is higher, often becomes the product alone, and supporting serial ports, ethernet or wireless still need in the in-service use upload data to data center.

And (4) rainfall is collected by using a rainfall bucket and then reported to a data center by an RTU. Generally, a relatively open place is selected for installation.

The video is mainly used for on-site confirmation, and when the sensing system gives an alarm, crisis confirmation is carried out through video scheduling. The method is generally implemented by a video camera + DVR or an IP camera + router.
