Technical Field

The disclosure relates to the technical field of data processing, and in particular relates to a roadbed engineering settlement monitoring method and device and electronic equipment.

Background

The roadbed deformation monitoring system has a lot of researches at home and abroad, but more laboratory states, less projects, mass production of products and less mass application. Usually, a roadbed deformation monitoring system adopts a hydraulic principle, is connected through an air pipe, a liquid pipe and a data line to form an on-site monitoring equipment unit, and is buried in the field of the wasteland. And an industrial control equipment box, a datum point, a liquid box and the like are connected to the outer side of the slope angle of the roadbed. Wireless transmission to the internet is acquired periodically. The network data platform is responsible for receiving the sensing data, recording logs, analyzing the data and displaying the data. As sensor access types increase, the demand on the server will increase.

If the sensor is better produced, the stability and the reliability are rarely improved. The internet data platform is simultaneously accessed to various sensors, the communication protocols of the sensors are not uniform, the data formats are different, and the concurrent processing capability of the server is very important after a large number of sensors are simultaneously accessed.
