Embodiment 1

[0040] Such as image 3 As shown, the engineering structure in Embodiment 1 of the present invention is a subway shield tunnel 8, and each ring is composed of six segments.

[0041] Such as figure 1 As shown, a project risk wireless perception and early warning visualization system is constructed on a certain subway shield tunnel 8, including sensor module 1, microprocessor module 2, wireless transceiver module 3, on-site early warning module 4, data storage module 5, and remote early warning module 6 And host computer 7, sensor module 1 is arranged in engineering structure, connects microprocessor module 2, and microprocessor module 2 connects wireless transceiver module 3 and host computer 7 respectively, and wireless transceiver module 3 connects field warning module 4, data storage respectively Module 5 and remote early warning module 6, the on-site early warning module 4 is arranged on the project site, the remote early warning module 6 is arranged in the remote monitori...

Embodiment 2

[0063] Such as Figure 4 As shown, the engineering structure in Embodiment 2 of the present invention is a certain foundation pit engineering 10 .

[0064] In the second embodiment of the present invention, the sensor module 1 adopts a stress sensor, which is arranged outside the lateral support of the foundation pit and can be used to monitor the axial force of the support in the foundation pit. The stress sensor is fixed on the lateral direction, and when the support is stressed, the stress sensor is stressed simultaneously with it, and outputs a corresponding electrical signal. The tilt sensor is set on the building structure affected by the foundation pit and can be used to monitor the safety status of the building structure. The tilt sensor is fixed on the building structure, and when the building structure deforms, the tilt sensor deforms simultaneously with it and outputs a corresponding electrical signal.

[0065] The microprocessor module 2 is connected to the senso...

The system comprises a sensor module, a microprocessor module, a wireless receiving and transmitting module, a site early-warning module, a data storage module, a long-distance early-warning module and an upper computer. The sensor module is arranged in an engineering structure and is connected with the microprocessor module. The microprocessor module is connected with the wireless receiving and transmitting module and the upper computer respectively. The wireless receiving and transmitting module is connected with the site early-warning module, the data storage module and the long-distance early-warning module respectively. The site early-warning module is arranged at an engineering site, the long-distance early-warning module is arranged in a long-distance monitoring room, and the data storage module is connected with the upper computer. Compared with the prior art, the engineering-risk wireless-sensing early-warning visualization system and method are used for safety monitoring and early-warning of the civil engineering, a monitoring theory, an engineering risk theory and an automatic control theory are combined, the limitation of an existing monitoring and early-warning method is broken through, real-time feedback and timely early warning are achieved, and safety in the engineering construction and operation process is guaranteed to the maximum degree.

Description

technical field [0001] The invention relates to a real-time monitoring and early warning system and method, in particular to a project risk wireless perception and early warning visualization system and method. Background technique [0002] With the continuous deepening of reform and opening up and the rapid development of the national economy, my country has ushered in a large-scale construction climax, and a large number of civil engineering projects have been built, including houses, tunnels, bridges, and dams. At the same time of large-scale construction, there are endless accidents in the construction and operation of projects, and more and more attention is paid to the monitoring and early warning of engineering structures. Public housing, urban bridges, tunnels and other facilities are urban lifeline projects. Once an accident occurs, the consequences will be unimaginable. Therefore, safety monitoring and early warning of the project are very important. [0003] At p...
