Building safety is related to people's life safety and social stability. How to ensure the safe use of buildings is an extremely important work. At present, more and more buildings in China are gradually approaching or have reached the service life, which makes buildings constantly appear various potential safety hazards. If we do not actively take relevant measures, it will hinder the sustainable and healthy development of society; At the same time, we should actively respond to the policy guidance of "energy conservation, environmental protection and low carbon" proposed by the state. It is urgent to study the monitoring, identification and reinforcement of dilapidated building structures.

Architecture design

The overall architecture of the building structure monitoring system is divided into two parts: the sensor network deployed in the field and the online monitoring cloud platform. The realization method is to deploy wireless inclination sensors in key parts of the structure to form a sensor network, and transmit the monitoring data to the cloud platform in real time through 2g/3g/4g network. The cloud platform carries out a variety of intelligent algorithm analysis on the monitoring data. Administrators with various permissions can access monitoring data, view early warning information, download relevant statistical reports and data analysis reports through web pages or mobile app.

Core advantages

① Adopt domestic advanced high-precision wireless inclination sensor products;

② Flexible ad hoc networks and highly integrated sensor functions reduce the types of sensors;

③ The installation can minimize the environmental impact on the site, the intelligent networking of sensors and gateways, and the network connectivity is high;

④ Low power consumption: low power consumption mechanism is embedded, which can be used continuously for many years with low maintenance cost;

⑤ Front end Intelligence: the front-end task system can be flexibly configured as required, embedded with a variety of information extraction and recognition algorithms to reduce the difficulty of using sensors;

⑥ Fine industrial design: small size, light weight, no cable, fast and convenient installation, which can significantly reduce the construction and installation cost;

⑦ Ip67/ip68 packaging standard: excellent dust-proof, waterproof and lightning protection performance.

Wuxi Yangming Street Zhongqiao and Zhonglian new village housing safety monitoring project

Project overview

In May, 2022, Wuxi City launched the reconstruction project of the old residential area in Yangming street, piloting the "epc+o" that is, the design, construction and operation integrated transformation mode. The designer and the constructor are also the future operators. Wireless inclination sensors were installed on the dilapidated houses in Zhongqiao village 2 and village 3 for house safety monitoring.

Solution

● products: more than 1500 sets of fg-wm400 wireless inclination sensors are used;

● data: wireless return with customized frequency. Discover defects and hidden dangers in time through big data and artificial intelligence;

● cloud platform: collect data in real time, combine it with the house map, and give accurate warning.

Customer value

● the manager monitors the safety status of the building all day long;

● improve the efficiency of building structure safety supervision;

● the hidden danger of housing safety was warned once in time and successfully solved.
