Problems solved by technology

[0006] 1. The versatility is not strong enough, and manufacturers mainly focus on sensors, only for their own products;
[0007] 2. Single function, only for a certain type of sensor;
[0008] 3. The scalability is not strong, and the number of channels is fixed;
[0009] 4. No cloud computing, only provide remote reporting and query;
[0010] 5. Not intelligent, unable to learn the impedance characteristics of on-site sensors and diagnose and eliminate faults
[0011] In addition, a sensor collection point on the monitoring site (generally skilled in the art is called a monitoring section) often has multiple sensors (several or even dozens) of different types from different manufacturers, and the difficulty of installation, wiring and communication is relatively high. Big
At the same time, there are often multiple working surfaces and various heavy machinery working on the site, and the scene is complex. During the monitoring process, the sensor body is damaged, and the sensor line is crushed by the excavator, causing open circuit and short circuit faults. This not only affects the monitoring data. Accuracy, but also affect the stability and safety of the acquisition equipment itself, the damage of lines and sensors can easily cause damage to the acquisition equipment, resulting in no data on the entire section

Abstract

The invention discloses an intelligent acquisition system for structural safety of large buildings. The intelligent acquisition system comprises a central operation and processing unit and a power management unit and further comprises a local storage unit, an acquisition unit, a programmable switch array, an open circuit / short circuit diagnostic unit, an RS485 communication unit and a public network communication module which are connected with the central operation and processing unit. The programmable switch array is connected with the acquisition unit through the open circuit / short circuitdiagnostic unit, and meanwhile, the programmable switch array is connected with n sensor interfaces, wherein n is equal to or greater than one. The acquisition unit comprises a vibration string excitation and receiving unit, a resistance acquisition unit, a voltage acquisition unit and a current acquisition unit. The public network communication module is provided with a separate antenna. According to the intelligent acquisition system, primitiveness and authenticity of data at the acquisition end are ensured, calculation and analysis are put into a cloud server, thus field data diddling uploading can be completely eradicated, big data analysis is also facilitated, and safety performance analysis and setting of a threshold value are facilitated.

Description

technical field [0001] The invention relates to the field of large-scale building structure safety monitoring, in particular to an intelligent acquisition system for large-scale building structure safety. Background technique [0002] Since the reform and opening up, China's urbanization and infrastructure development can be described as rapid, especially in recent years, high-speed railways, subways, highways, hydropower dams, super long-span bridges, high-rise buildings and other large buildings have been constructed at a fast speed, the number of As many as the world's attention. The structural safety and stability of these buildings are very important, and various collapse events and dangerous buildings also occur from time to time. Therefore, various high-precision sensors are used to measure and monitor the construction of such buildings and even the use process in real time to provide feedback Its structural health status provides early warning for abnormal condition...
