Design for Crack Detection System of Wall in Houses Based on SCM

In order to understand the data of crack of wall in houses as much as possible and ensure the safety of life and property of residents, a kind of crack detection system of wall in houses based on SCM was designed to detect the crack of wall in houses. In the system, the main work includes the design for data acquisition module of crack in the wall and data receiving and processing control module. For detailed, the work can be divided into selection of sensor detecting cracks, hardware design and software design of the system. The hardware design consists of the design of data acquisition module and data receiving and processing control module, and the software design consists of the design of data acquisition program and data receiving and processing control program and so on. Finally, the hardware and software of system designed were debugged and it proved that the desired effect was achieved for the design in practice. [PUBLICATION ABSTRACT]
