A BIM-Based Prefabricated Building Stress Monitoring System
[0001] The utility model relates to a BIM - based prefabricated building stress monitoring system.
[0002] The technology of prefabricated building is becoming more and more mature. However, most of the prefabricated components are prefabricated in the factory and installed on site, the stress of some key parts of the prefabricated component is unclear and the information of the building model is incomplete.
[0003] In view of the above, the purpose of the utility model is to provide a BIM - based prefabricated building stress monitoring system, which ensures the safety of the prefabricated component and can carry out remote visual real-time monitoring.
[0004] This system includes resistance strain gauges, RFID sensor tags, RFID Reader, database management platform and BIM platform.
[0005] Further, the resistance strain gauges and RFID sensor tag are installed on the surface of the prefabricated component, and RFID sensor tags are used to collect strain data.
[0006] Further, the resistance strain gauge is installed on the weak parts of the beam and column. For prefabricated beams, the resistance strain gauges are installed on the middle of the bottom surface and the top surface. The resistance strain gauges are installed on four sides of the upper, middle and lower parts of the prefabricated column. Each prefabricated component has an RFID sensor tag attached to the angle above the inner sides of the beam or the column.
[0007] Further, the RFID reader is connected to the RFID sensor tag, which is used to collect information in the tag. The database management platform is connected to the RFID reader, which is used to receive and analyze the information sent by the RFID reader.
[0008] Further, in the above system, the ADC module in the RFID tag is used to obtain the strain information of the resistance strain gauge. The MCU inside the RFID sensor tag is used to package the strain information and address coding information (the label number) and transmit them to the RFID reader through radio frequency wireless communication.
[0009] Further, the database management platform is connected with the BIM platform to update the attribute information of the BIM model. The critical stress value of each prefabricated component is set in the BIM platform to give a warning when the stress exceeds the safety stress value.
[0010] FIG. 1 is the structure diagram of a BIM - based stress monitoring system for prefabricated buildings.
[0011] Hereinafter, the embodiments of the present system will be described in detail with reference to the accompanying drawings.
[0012] Referring to FIG.1, a system for monitoring prefabricated building stress based on BIM, including sensor module 1, communication module 2, database management platform and BIM platform. The resistance strain gauges11 and RFID sensors tags2l are installed on the surface of the prefabricated component. RFID sensors tags2l are used to collect strain data of prefabricated components measured by resistance strain gagues11. The RFID reader22 is connected to the RFID sensor tags21, which is used to collect information in the RFID sensor tags21. RFID reader22 is connected to database management platform, data receiving module31 is used to receive signals from RFID reader22, and data analysis module32 is used to analyze data. The database management platform is connected with BIM platform, which is used for information update module4l in BIM platform4. When the stress of the prefabricated component exceeds the safe stress value, the warning module42 is started.
[0013] The resistance strain gauge 1is KFG foil resistance strain gauge. The resistance strain gauge is installed on the weak parts of the beam and column. For prefabricated beams, the resistance strain gauges11 are installed on the middle of the bottom surface and the top surface. The resistance strain gauges11 are installed on four sides of the upper, middle and lower parts of the prefabricated column. Each prefabricated component has an RFID sensor tag21 attached to the angle above the inner sides of the beam or the column.
[0014] RFID sensor tag2l system is composed of main controller MSP430F149, clock module DS1302, wireless communication module nRF905, storage module 24LC256 and power supply module AMSLL17-3.3.MSP430 F149 is characterized by low power consumption, fast processing speed and abundant on-chip resources. It can convert the analog voltage output signal of strain signal conditioning circuit into digital signal by using its internal ADC module. The storage module adopts 24LC256 to store the collected data. DS1302 is adopted in the clock module to record the time value corresponding to the strain signal. The wireless communication module adopts nRF905 to realize the wireless transceiver of data. The power supply module adopts ASMLL17-3.3 to convert the 5V DC power into 3.3V, providing stable working voltage for MCU and other chips.
[0015] The RFID reader22 is composed of main controller MSP430F149, wireless communication module nRF905, storage module 24LC256, serial communication module MAX3232 chip and power supply module AMSLL17-3.3. Different from RFID sensor tag2l, a serial port communication module is added in the hardware design of RFID reader22 to realize the conversion between the computer's RS232 level and the TTL level of the master controller. RFID reader 22 can not only receive control commands of upper computer and send them to RFID sensor tag21 wirelessly through serial port, but also receive monitoring data sent by RFID sensor tag2l wirelessly and send them to upper computer for processing.
[0016] Resistance strain gauges11 are used to start strain measurement after prefabricated component assembly is completed. RFID sensor tags2l are used to obtain strain information of resistance strain gauges11.The MCU inside the RFID sensor tags2l is used to package it with address coding information (label number) and transmit them to RFID reader22 through radio frequency wireless communication. RFID reader 22 is used to demodulate and decode the received signals and send them to the background computer controller. The computer interface is used to transfer the information to the data receiving module 31, and the data analysis module 32 is used to analyze the data.
[0017] Further, information update module 41 not only has the stress information of the prefabricated components, but also includes the location, dimension, reinforcement, date of manufacture and other information of the components.
[0018] The database management platform3 is used to update the information to the graph element of the corresponding prefabricated component in BIM platform4. BIM platform4 sets the critical stress value of each component and starts the warning module 42 when the data exceeds the stress value.
