As Figure 1-4, the hangar system 2 that Hanging Basket mainly comprises the main truss system 1 be fixed on case beam 4, is fixed on the installing rack 3 in main truss system 1 and is hung on below installing rack 3, in order to ensure the safety of cradle construction, need carry out Real-Time Monitoring to Hanging Basket each several part data, concrete grammar is as follows:
[1] selected some measuring points in main truss system 1, each measuring point arranges strain gauge, and in order to measure the stress value of main truss system, the measurement category of strain gauge is 0 ~ 700 ton;
Same selected some measuring points on installing rack 3, each measuring point is arranged level gauge sensor, in order to measure the levelness (i.e. deformation quantity) of installing rack 3, the measurement category of level gauge sensor is 0 ° ~ ± 15 °, this external installing rack 3 is also provided with an air velocity transducer, in order to measure the air speed value at installing rack 3 present position place;
Same, selected some measuring points in hangar system 2, the vertical cloth displacement sensor in each point position place, in order to measure the vertical amount of tension of suspension cable in hangar system 2, measurement category is 0 ~ 8mm;
[2] on Hanging Basket, arrange monitoring terminal main frame after, each sensor be arranged on Hanging Basket be connected with monitoring terminal main frame through cable in previous step, this monitoring terminal main frame is by wireless network and the server wireless connections being positioned at ground; Sensor on Hanging Basket each several part by the data that monitor by monitoring terminal main frame real-time Transmission in server;
[3] there is data memory module and data processing module in server, data memory module is connected with display and shows received monitored data over the display in order to the form by chart, data processing module is then in order to carry out Treatment Analysis to received monitored data, to decision making to the state of Hanging Basket each several part, be specifically divided into [normal condition], [doubtful abnormality] and [abnormality] three kinds; Before judging, the threshold a of setting installing rack levelness and b, the stress threshold c of setting main truss system, the amount of tension threshold d of setting hangar system and e, wherein, a < b, d < e, and the value of a-e is determined according to concrete engineering actual state;
[4] as shown in Figure 2, data processing module is real-time calling stress monitoring data from data memory module, to judge the real-time status of main truss system 1;
If during stress≤c that the strain gauge in main truss system 1 monitors, then judge that main truss system 1 is in [normal condition];
If during the stress > c that the strain gauge in main truss system 1 monitors, then judge that main truss system 1 is in [abnormality], main truss system 1 is in dangerous construction, server stops the instruction of construction by sending to Hanging Basket, send a warning message to supervisor of construction's mobile phone simultaneously, data processing module also can show the position that main truss system 1 breaks down over the display, so that supervisor of construction further processes measure;
[5] as shown in Figure 3, data processing module is real-time calling levelness monitored data from data memory module, to judge the real-time status of installing rack 3;
If during levelness≤a that the horizon sensor on installing rack 3 monitors, then judge that installing rack 3 is in [normal condition];
