[0161] Please refer to Figures 7 to 9 The fourth embodiment of the present invention further provides a template support safety monitoring system 500, including an integrated sensor device 510, a positioning module 520 and a controller 530, wherein:

[0162] The integrated sensing device 510 integrates an axial force sensor 513 , a displacement sensor 511 and an inclination sensor 512 . There are multiple integrated sensing devices 510 , which are respectively arranged on the monitoring rods 111 of the vertical rods 110 of the formwork support 100 .

[0163] The positioning module 520 is disposed on at least one monitoring rod 111 of the vertical rod 110 of the formwork support 100 .

[0164] The controller 530 is connected to the axial force sensor 513, the displacement sensor 511 and the inclination sensor 512 of the integrated sensing device 510. The controller 530 calculates the global pressure stability coefficient of all vertical rods 110 of the formwork support 100 in the predetermined area through formulas (1) to (3).

[0165] In order to avoid the system being too decentralized, at least the controller 530 can be integrated into the integrated sensing device 510 .

[0166] Please refer to Figure 8 In order to realize local and remote monitoring of the formwork support 100, the formwork support safety monitoring system 500 provided in the fourth embodiment of the present invention may further include:

[0167] The local data display terminal 540 is connected to the controller 530 and is used to display the pressure value, distance, displacement, inclination, global pressure stability coefficient, global displacement stability coefficient and global inclination stability coefficient data and the overall safety monitoring result of the formwork support 100. This allows construction workers to monitor the safety status of the formwork support 100 through the local data display terminal 510.

[0168] The local alarm 550 is connected to the controller 530. When the global pressure stability coefficient, the global displacement stability coefficient and the global inclination stability coefficient exceed the warning value, the local alarm sends out an alarm to remind the construction workers that they are in a dangerous construction environment.

[0169] The server 560 is connected to the controller 530 and is used to receive pressure values, distances, displacements, inclination angles, global pressure stability coefficients, global displacement stability coefficients and global inclination stability coefficient data as well as overall safety monitoring results of the template support 100 .

The remote data display terminal 570 enables the construction management personnel to monitor the situation in time, so as to collect corresponding rescue measures in time according to the monitoring situation and reduce the damage.

[0171] The formwork support safety monitoring method and system 500 provided in the fourth embodiment of the present invention monitors the overall safety of the formwork support 100 by calculating the global pressure stability coefficient, global displacement stability coefficient and global inclination stability coefficient of all vertical rods 110 including the monitoring rod 111 and the conventional rod 112, so as to comprehensively evaluate the overall safety of the formwork support 100 through the three dimensions of global pressure stability coefficient, global displacement stability coefficient and global inclination stability coefficient. Compared with the scheme of monitoring the deformation of the rod 111 without monitoring the deformation of the conventional rod 112 in the prior art, it has the effect of improving the accuracy and comprehensiveness of the overall safety monitoring of the formwork support 100 from multiple dimensions. Correlating the global pressure stability coefficient, the global displacement stability coefficient and the global inclination stability coefficient can improve the reliability of monitoring.

[0172] The formwork support safety monitoring method and system 500 provided in the fourth embodiment of the present invention can automatically determine the overall safety status of the formwork support 100 and give an alarm. A risk judgment index system can be established first, and then the automatic detection data can be constructed into a data matrix, and the stability coefficient index of the three dimensions can be used to judge whether the data is an alarm. The judgment is divided into two levels: single rod and overall rod, to determine whether the type of hazard source in the formwork support is a problem with a single vertical rod or a problem with the integrity of all vertical rods of the formwork support.

Obviously, the above-mentioned embodiments are only some embodiments of the embodiments of the present invention, but not all embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.
