Wall crack comprehensive monitoring and early warning system

Abstract

The invention relates to the field of house wall structure monitoring and early warning, and particularly relates to a wall crack comprehensive monitoring and early warning system. One side of a wallto be tested is provided with a first displacement sensor and a second displacement sensor at a pre-determined distance. The first displacement sensor and the second displacement sensor are both fixedon one side of the wall. A high flexibility metal measuring rope is connected to corresponding sides of two displacement sensors. The middle of the high flexibility metal measuring rope is provided with a semiconductor stress sensor patch. One side of the wall to be tested is provided with a temperature sensor and a buzzer alarm. The system monitors the development trend of crack width of the wall and the temperature changes of different positions in the wall through a data information collecting module composed of a plurality of sensors, monitors in real time through a monitoring center, andsets different early warning levels. If the threshold value is exceeded, the system makes timely early warning, which greatly improves monitoring efficiency.

Description

technical field [0001] The invention relates to the field of monitoring and early warning of house wall structures, in particular to a comprehensive monitoring and early warning system for wall cracks. Background technique [0002] Due to geological disasters, its own structure and disrepair, cracks have a major impact on the safety, applicability and durability of the building structure. In order to avoid accidents and accurately judge the development of cracks in the wall structure, it is necessary to detect the changing trend of the width of the cracks in the wall structure in real time, and deal with them in time when the cracks exceed the safe range; currently there are many crack monitoring methods, However, most of them are manual mechanical monitoring, and the degree of automation is low; therefore, the present invention provides a comprehensive monitoring device for wall cracks, which wirelessly transmits various monitoring data to the monitoring center, and activat...

In order to avoid the occurrence of accidents and accurately judge the development of cracks in the wall structure, it is necessary to detect the change trend of the width of the cracks in the wall structure in real time, and deal with them in time when the cracks exceed the safe range; currently there are many crack monitoring methods, However, most of them are manual mechanical monitoring, and the degree of automation is low; therefore, the present invention provides a comprehensive monitoring device for wall cracks, which wirelessly transmits various monitoring data to the monitoring center, and if any abnormality is found, the buzzer alarm will be activated in time

[0003] The manual monitoring method mostly uses a vernier caliper to measure the distance between the crack mark points arranged on both sides of the crack, and analyze the crack change trend. The crack mark points of this method are prone to loosening, and the crack deformation cannot be found in time;

[0004] At present, some existing real-time dynamic crack detection devices mostly embed the sensor inside the wall. If the sensor is damaged, it is not convenient to replace it in time, and it lacks an early warning device, so it cannot remind the people in the house to evacuate in time; therefore, the present invention provides a A comprehensive monitoring device for wall cracks, which wirelessly transmits a variety of monitoring data to the monitoring center. If any abnormality is found, the buzzer alarm will be activated in time
