Problems solved by technology

[0003] The automatic measurement and reading static level system has the characteristics of simple principle, stable precision, automatic measurement and reading, automatic recording, and automatic monitoring data management and analysis. , communication devices and supporting acquisition and management software can work normally, so the system investment is large, and the system has high requirements for lightning protection and grounding, and the communication control cable distance is long, the probability of system failure is also high. Only the key parts of the project can be used, which limits its scope of use

Embodiment Construction

[0028] in accordance with figure 1 and figure 2 Describe the specific implementation of the mobile measuring and reading type static leveling system.

[0029] The static level tube 1 is processed by steel pipe, the bottom of the tube is sealed and has a base structure, the bottom has a connection structure with the connecting pipe 2, and the top has a matching structure with the probe and a protective cover.

[0030] Connecting pipe 2 selects the flexible pipe that anticorrosion performance is better for use.

[0031] The stylus is composed of a stylus, an encoder, a control module, a communication module and a housing. The upper part of the stylus is threaded and connected to a stepping motor. During operation, the stylus is controlled by the control measuring instrument 6 to go down. When the stylus goes down When reaching the water surface, the stylus and the water surface pass through the metal tube and form a closed circuit with the stylus, the stylus stops, the motor ...

Abstract

The invention discloses a mobile sensing type hydrostatic leveling system and a method for monitoring vertical displacement deformation. In order to improve the reliability and universality of the sensing type hydrostatic leveling system and reduce the cost, the leveling system comprises a reference hydrostatic leveling barrel for containing liquid on a stationary point, multiple measuring point hydrostatic leveling barrels for containing liquid and arranged on deformation points, and a distance measurement device used for measuring the distance between the liquid level in the hydrostatic leveling barrel and the top end of the hydrostatic leveling barrel; the lower parts of adjacent two hydrostatic leveling barrels are connected in series through a corresponding communicating pipe. The system is simple in structure, stable in precision, simple and convenient in range adjustment, semi-automatic in sensing, automatic in recording, low in construction cost and good in effect, and the operating cost is reduced.

Description

technical field [0001] The invention relates to a mobile measuring-reading static leveling system for monitoring engineering deformation and a method for monitoring vertical displacement and deformation, which is suitable for specific situations of vertical displacement and deformation monitoring. Background technique [0002] Under the existing technical conditions, the static leveling system is usually used to monitor the vertical displacement and deformation of engineering buildings. The static level system is composed of a static level and a connecting pipe. The static level system is divided into two forms: manual measurement and automatic measurement and reading. The manual measurement and reading system is rarely used in engineering deformation monitoring due to its low precision. The automatic measurement and reading system It is composed of an automatic reading static level, an acquisition device, a communication device, and corresponding acquisition and management ...
