Embodiment 1

[0022] A high-speed railway station long-span space steel structure health monitoring sensor system, which is equipped with

[0023] Multiple environmental monitoring devices monitor the physical environment of the long-span steel structure;

[0024] A plurality of network node detection sensors, the plurality of detection sensors are set at the target nodes of the long-span space steel structure, and perform performance monitoring on the target nodes; and

[0025] The data memory is respectively connected with the environmental monitoring device and the network node detection sensor, and reads and stores the data detected by the environmental monitoring device and the sensor.

[0026] Among them, the plurality of environmental monitoring devices at least include monitoring parameters in terms of temperature, humidity, corrosiveness, wind speed, and sunshine. By monitoring the temperature, humidity, corrosion degree, wind speed, and sunshine duration, the service environment ...

Embodiment 2

[0060] A health monitoring sensor system for large-span steel structures in high-speed railway stations, taking the monitoring of grid steel structures in the Haikou East Station of the Hainan Ring Island High-speed Railway as an example for illustration.

[0061] The steel structure health monitoring device is equipped with multiple environmental monitoring devices to monitor the temperature, humidity, corrosion degree, wind speed, sunshine, etc. of the environment where the grid steel structure of the high-speed railway station is located.

[0062] Temperature monitoring uses a temperature monitor with a model number of CTI-155X for temperature detection. Humidity monitoring adopts WKT-R-150ZS of Vecometo for humidity monitoring. PosiTector SST salinity tester is used for environmental salinity measurement, EC450 wind speed detector is used for wind speed detection, and PeopleSoft illuminance transmission is used for sunshine duration monitoring.

[0063] It should be noted...

Abstract

The invention relates to a high-speed railway station large-span spatial steel structure health monitoring sensing system. The system comprises multiple environmental monitoring devices which are usedfor monitoring the physical environment where a large-span spatial steel structure is located, multiple network node detection sensors which are arranged at the target nodes of large-span spatial steel structures to perform performance monitoring on the target nodes and a main processors which is electrically connected with the environmental monitoring devices and performs analysis and processing. Accordingly, the health condition of the high-speed railway station large-span spatial steel structure can be monitored in real time, and the defect location can found in time.

Description

technical field [0001] The invention relates to the technical field of steel structure health monitoring, in particular to a high-speed railway station large-span space steel structure health monitoring sensor system. Background technique [0002] At present, high-speed rail passenger station buildings and platform steel structure canopies mostly adopt the form of large-scale, large-span, and complex structural systems such as grids and trusses. For example, Guangzhou Railway Group has Guangzhou South, Shenzhen North, Haikou East, Sanya and other 70 Each station adopts large-span space steel structure. [0003] The steel structure station buildings and platform canopies of high-speed rail passenger stations are different from ordinary civil buildings. Due to the large passenger flow of high-speed rail stations, the main structure and structural components that cannot be replaced during use are designed for durability according to the service life of 100 years. Stations in c...
