Abstract

The invention discloses a steel structure performance measurement and control circuit system based on a piezoelectric principal element rod piece. An output signal of a sensor is acquired by a controllable silicon control circuit, and the acquiring process is controlled by an AD front end path controller connected with the controllable silicon control circuit; the controllable silicon control circuit is connected with an AD card of a computer, a DA card of the computer is connected with a boost converter, and the computer is connected with a singlechip coding control circuit to process the signal; and the boost converter is connected with one controllable silicon control circuit, and the controllable silicon control circuit is connected to a control motor, and is connected with a DA rear end path controller to control signal output. The system provided by the invention can combine and unify structural steel construction detection and control techniques, can apply forward or backward voltage for control according to the need, can carry out effective on-line monitoring and real-time monitoring, and has high practicability.

Description

technical field [0001] The invention relates to the technical field of steel structure building detection and control, and more specifically relates to a steel structure performance measurement and control circuit system based on piezoelectric principal element rods. Background technique [0002] Steel structure is one of the most widely used forms of engineering structures at present. Because steel has the characteristics of light weight and high strength, and its cross-section is relatively thin, it often causes the structure to be damaged by strange instability and dynamic performance. Once this damage occurs, the structure will follow collapse with catastrophic consequences. Therefore, it is of great significance to social production and life to study the dynamic performance of steel structures, master the characteristics of vibration amplitude, stress and frequency of this type of structure, timely diagnose its safety, and take corresponding technical control measures. ...
