Embodiment
As shown in Figure 1, a kind of three-dimension virtual reality health monitor method of steel structure net rack draws together data acquisition, health evaluating, three-dimension virtual reality and monitoring terminal four steps, and concrete steps are as follows:
Data acquisition: data collection layer is for gathering inherent parameters and environmental parameter, and the information that data collection layer collects by data pretreatment carries out Unified coding.
Health evaluating: pretreated data are transferred to data processing centre (DPC) by internet or LAN (Local Area Network) by data pretreatment, data processing centre (DPC) carries out overall treatment to the information sent, according to frequency and the vibration shape change at a rack position, obtained the degree of impairment at each position of rack by model analysis; Rack health evaluation system passes through the health status that the degree of impairment of rack and the stressing conditions of rod member for grid and the environment comprehensive residing for rack analyze rack, starts warning system after finding danger.
Three-dimension virtual reality: rack health status is intuitively presented on three-dimensional model by three-dimension virtual reality system; The health status of three-dimension virtual reality system display rack directly perceived in rack three-dimensional model, the degree of injury of rack corresponding position is represented with the transparent block of different colours, the stress situation of corresponding rod member is represented with the shade of rod member, if the darker rod member of color is in the heavier position of damage, then this place's health status is poor.
Monitoring terminal: the three-dimensional model of reflection rack health status is uploaded to the webserver, and the webserver can provide access for the network equipment; The network equipment can get information about the health status of rack by client; Obtain the health and fitness information of rack whenever and wherever possible, process rack Problems existing timely and effectively.
As shown in Figure 2, data collection layer is made up of rack inherent parameters pick-up transducers and environmental parameter pick-up transducers, and wherein, rack inherent parameters pick-up transducers comprises strain transducer, acceleration transducer and amount of deflection sensor.Environmental parameter pick-up transducers comprises rain sensor, snowfall sensor, air velocity transducer and temperature sensor; Corresponding being arranged on steel structure net rack of the sensor.Sensor not only gathers the parameter of rack itself, also gathers relevant environmental parameter.By theory calculate, provide sensor optimal placement position.Because grid structure is complicated, and the quantity of sensor is more, and the wiring of conventional wired sensor is very difficult is irrealizable sometimes.Described various sensors in the present invention adopt wireless senser.
Principle of work: the information that different sensors collects by signal pre-processing system carries out Unified coding, and by internet by information transmission to data processing centre (DPC).Data processing centre (DPC) obtains truss damage situation by modal analysis method, is obtained the stressing conditions of rack by finite element method, and combining environmental combined factors analyzes the health status of rack.Comprehensive assessment is carried out to its security and adaptability, searches potential safety hazard.When rack exists potential safety hazard, notify relevant staff with the form of note, and under transferring the warning system notice rack in rack, personnel withdraw.The rack health status that three-dimension virtual reality system obtains according to data analysis, reflects intuitively, as shown in Figure 3 in the three-dimensional model of rack.The damage situations of rack shown with the transparent cake of different color with bulk, the stress situation of rod member reflects with rod member shade.When the larger rod member of stress appears at impaired serious position, namely illustrate that this position needs to carry out reinforcing or more renewing rod member.And varying environment parameter shown in the three-dimensional model in the mode of different background look, and represent the severe degree of environment according to the depth of color.Rack three-dimensional health status is uploaded to the webserver.Computing machine and smart mobile phone etc. can pass through client-access server, understand the health status of rack whenever and wherever possible.And the long-range negotiation of the relevant staff contributing to different location, processes the health problem that rack exists better.When rack exists potential safety hazard, notify relevant staff with the form of note, and under transferring the warning system notice rack in rack, personnel withdraw.
Specific works flow process is as follows:
1, sensor installation.By modal calculation, with allocation optimum, corresponding sensor is installed on rack, comprises strain transducer, amount of deflection sensor and acceleration transducer and rain sensor, snowfall sensor, air velocity transducer and temperature sensor.
2, by 3 d modeling software, the three-dimensional model of steel structure net rack is set up, and the type of mark sensor and installation site in a model.
3, signal pre-processing system, the various signals collected by sensor are converted to digital signal, and by internet, these data are transferred to data processing centre (DPC).
4, data processing centre (DPC).According to frequency and the vibration shape change at a rack position, obtained the degree of impairment at each position of rack by model analysis.
5, Data processing rack health evaluation system in the heart.Environment comprehensive residing for the degree of impairment of rack and the stressing conditions of rod member for grid and rack is analyzed the health status of rack, after finding danger, start warning system.
6, warning system.Warning horn installed by rack, can accept the instruction of health evaluation system, when rack is in the hole, under can notifying rack, personnel withdraw in time.The obvious hidden danger that warning system can also be existed by SMS notification relevant staff rack.
7, three-dimension virtual reality system.Can by health status current for rack, being virtually presented in rack three-dimensional model, is the health problem that staff can get information about rack and exists.
8, the webserver.The three-dimensional model of reflection rack health status can be uploaded to the webserver, for the network equipment provides real time access.Staff can understand the current health status of rack by the computing machine of networking or smart mobile phone, and can the scheme of handling hidden danger long-range with related personnel.
