Description

technical field [0001] The invention relates to the technical field of civil engineering equipment, in particular to a hub for improving the connection mode between signal lines and sensors in civil engineering model tests. Background technique [0002] With the vigorous development of civil engineering in China, in the face of increasingly complex geological conditions and construction conditions, it is imminent to tackle key problems in advanced theories, and geotechnical experiments are an important method to verify existing theories and discover new theories. With the rapid development of information technology and electronic equipment, test data are often collected and analyzed by electrical measurement. The electrical measurement method needs to connect the sensor and the acquisition device through a signal line. At present, there are the following defects in the connection method between the signal line and different types of sensors: (1) The connector is loose, whic...

AI Technical Summary

Problems solved by technology

The current connection methods between signal lines and different types of sensors have the following defects: (1) The connector is loose, which is easy to cause open circuit

Due to the different wiring sequences of different types of sensors such as stress, strain, and displacement sensors, in actual operation, the signal wires need to be manually peeled off for docking and then bonded with adhesive tape, resulting in weak joints and easy to cause open circuits in the test. , resulting in loss of data during the test; (2) There is no uniform identification of the joints

In some large-scale model tests in the field of civil engineering, it is often necessary to connect dozens of sensors. These joints do not have a unified mark, which makes it difficult for the tester to correspond the test data with the corresponding sensors one by one when processing the test data in the later stage. Difficulty in test analysis; (3) Difficulty in troubleshooting when a circuit break occurs

In the past, the one-to-one connection between the sensor and the signal line made the number of lines large and disorderly. When a circuit break occurred, it was impossible to accurately know whether the sensor was damaged or the joint was disconnected, which added uncertainty to the troubleshooting; (4) The connection lines were messy Disorder, resulting in safety hazards in the test process
