Abstract

The invention belongs to the technical field of a structural electrical measuring test method, and provides a sensor fast wiring and fault identifying system for an electrical measuring method. The system consists of junction boxes, a signal light switch control box and a computer. The function of the junction boxes is to realize fast wiring between a sensor and a measuring instrument through standard interfaces of the sensor. The junction boxes are fixedly connected with the measuring instrument and the signal light switch control box to enhance the construction efficiency of an electrical measuring system. An existing thousand-level large-scale electrical measuring channel makes the time cost of debugging and troubleshooting of the electrical measuring system soar, a fault location cannot be found out quickly and accurately, and the efficiency of a large-scale and complex electrical measuring test is seriously affected. According to the sensor fast wiring and fault identifying system, based on the wire number corresponding to the abnormal data collected by a strain meter, signal lights can be lightened, rapid locking of an abnormal connected wire is thus achieved, and the debugging and troubleshooting efficiency of the large-scale and complex electrical measuring test system is greatly improved. In addition, the sensor fast wiring and fault identifying system has the characteristic of reuse, and the construction efficiency of the large-scale electrical measuring test can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of structural electrical testing and relates to a sensor fast connection and fault identification system for electrical testing. Background technique [0002] The electrical measurement method is to measure the linear strain on the surface of the component through the resistance strain gauge, and then determine the stress state of the surface of the component according to the corresponding relationship between the strain and the stress. This method is to paste the resistance strain gauge on the surface of the component to be tested. When the component deforms under the action of force, the resistance value of the resistance strain gauge will change accordingly. The change of the resistance value of the strain gauge can be converted by the measuring instrument It is the change of voltage, and the stress or strain information of the component under the action of external force can be obtained through the measu...
