LORA-based deformation monitoring system and method with high precision positioning

Abstract

The invention provides an LORA-based deformation monitoring system with high precision positioning. The system comprises monitoring terminal equipment, an LORA transceiver module, LORA base stations, a server, and a cloud platform. The monitoring terminal equipment is equipped with navigation information units which can receive navigation information and original observation data, LORA transceiver modules, solar panels, and storage batteries. The LORA base stations are deployed in a service range with the need of coverage. The server receives the original observation data uploaded by a plurality of monitoring terminal equipment from the LORA base stations, a double-difference solution mode is used, on the basis of optimizing a carrier phase differential data processing method, the phase data of reference station and monitoring terminal equipment carriers are processed at the same time, and the accurate deformation of a monitoring point relative to the reference station is obtained. The cloud platform comprises data processing, analysis and management units. The LORA-based deformation monitoring system has the advantages of a wide coverage, high expansion ability, a short construction period, safe use and low use cost.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of satellite positioning and navigation, and specifically refers to a deformation monitoring system and method based on LORA-based high-precision positioning. [0003] 【Background technique】 [0004] The satellite navigation industry is not only related to national security, but also a sunrise industry that has a significant impact on the general public. At present, major powers and economic communities in the world attach great importance to satellite navigation technology and industry. The satellite navigation industry has experienced rapid development in the past ten years, but compared with the future, this industry is just in its infancy, and the market prospect is extremely broad. At present, in addition to the GPS system of the United States, Russia is stepping up the recovery of the GLONASS system so that it can be used stably by military and civilian users. In addition, Galileo in Europe an...

Problems solved by technology

The existing solutions are: if in the area covered by public network signals, use GPRS / 3G / 4G to solve it; in areas without signal, use radio stations and wireless AP relays; in field monitoring applications, even It is necessary to dig trenches to bury optical fibers and power supply cables, which brings many problems such as long construction period, high cost of communication hardware, continuous usage costs, data leakage, and difficulty in expanding access terminals
