Abstract

The invention provides an environment-friendly structure deformation early warning device, method and system. The invention relates to the technical field of structural deformation early-warning devices. The problems of long consumed time and inaccuracy of the traditional monitoring measurement are solved; the device comprises a strain gauge, a bridge circuit, an amplifier, a voltage comparator and an alarm. The strain gauge is arranged on a surface of a to-be-monitored structure. The bridge circuit is used for outputting a voltage value according to a received strain signal, the amplifier amplifies the voltage value and then inputs the amplified voltage value into the voltage comparator to be compared with a first preset threshold value, and when the amplified voltage exceeds the preset threshold value, the voltage comparator sends an alarm signal to the alarm, and the alarm gives an alarm; the device is simple in principle, light in structure, capable of saving manpower and materialresources, obvious in an early warning signal, environmentally friendly, free of pollution, capable of being repeatedly used and capable of effectively solving the problems that constructional engineering structure deformation monitoring investment is large and early warning signals are not obvious.

Description

technical field [0001] The present disclosure relates to the technical field of structural deformation early warning devices, in particular to an environment-friendly structural deformation early warning device, method and system. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] In construction engineering, steel structure and concrete structure are the most common structural forms. Under the action of self-weight stress and other additional stresses, steel structures and concrete structures in construction projects will produce strains and even large deformations. The strain generated by the structure is difficult to observe with the naked eye. Once there is a crack visible to the naked eye, a large deformation has already occurred, which has seriously threatened the safety of the entire building structure. Therefore, in order to ensur...
