[0014] A method for monitoring the state of the crossbeam during the construction process of a building, including the following steps:
[0015] Step 1: Preparation for the crossbeam construction. First, inspect and clean the surface of the crossbeam for defects. Then, apply resin coating for fixation to the bottom of the paint suction cup. Next, fix it through the insertion of the side rod of the fixing block into the fixing colloid. Under the limiting action of the metal fixing ring, fix the paint suction cup and the fixing holding plate at the bottom of the fixing colloid. At the same time, fix the target on the top of the fixing colloid using the fixing block. Then, place the protective housing on both sides of the top of the crossbeam, and connect multiple groups of pulsed light sources and detection circuits in series through the strain optical cable. According to the length of the crossbeam, fix multiple groups of fixing components at equal intervals on the strain optical cable. Here, the paint suction cup provides monomer adsorption and fixation, and under the conduction of the conductive wire, the paint suction cup can maintain verticality.
[0016] Step 2: Then, according to the position of the surface defects of the crossbeam, fixedly install the jitter monitoring component at the bottom of the lifting frame. During the lifting construction process, due to the vibration of the crossbeam construction, the moving column on its surface fluctuates up and down inside the detection coil, causing the detection coil to generate magnetic field cutting. Through the change of magnetic field data, the vibration data of multiple groups of fixing holding plates and the strain optical cable outside them can be detected. While detecting the vibration state of the crossbeam during the construction process, it can provide data on external influencing factors for the detection work of the pulsed light source and the detection circuit, and transmit this detection data to the control system through a wireless transmitter. Here, the control monitoring drone performs a sensing action with the target, and combines the detection data of the detection coil to exclude the jitter data of the target due to vibration during the detection of the crossbeam deformation, thereby improving the quality of the deformation monitoring of the crossbeam.
[0017] Step 3: When the pulsed light source propagates in the strain optical cable, the incident pulsed light will undergo backscattering to form different backscattered lights. Then, the detection circuit detects the frequency change of the backscattered light in the strain optical cable to sense the changes in temperature and strain reflected by the strain optical cable, directly obtaining the frequency data of the strain optical cable in each state, and then calculating and analyzing the change of the frequency shift data to obtain the strain.
[0018] Step 4: Then, the micro air pump provides a negative pressure action for the rotating base ball and the negative pressure suction cup, so that the first light sensing component and the reset spring are adsorbed and fixed at the bottom of the rotating base ball. The control system provides electrical energy for the arranged magnetic plates inside the magnetic isolation cylinder, and then the permanent magnetic sphere and the rotating base ball rotate inside the magnetic isolation cylinder due to magnetic field factors, so that the ball at the bottom of the second light sensing component can contact the crack on the surface of the crossbeam. Subsequently, the jitter data of the crossbeam crack during the construction lifting is detected through the light sensing detection function between the first light sensing component and the second light sensing component.
[0019] The present invention has the following advantages: The present invention provides an improved method and system for monitoring the state of the crossbeam during the building construction process. Compared with the same type of equipment, the following improvements are made:
[0020] The monitoring method and system for the state of crossbeams during building construction, through the distributed optical fiber monitoring technology of the comprehensive monitoring component, has the advantages of long distance, large range, high precision, dense measurement, etc. Compared with traditional point sensors, it is more conducive to obtaining a large amount of overall linear monitoring data of the object to be measured. By analyzing the strain and temperature coupling data in the optical fiber, the concrete strain distribution state of the crossbeam at different hoisting stages can be obtained; by setting up the jump monitoring component, the change in the distance between the first light sensing component, the reset spring and the second light sensing component is associated with the amount of deformation, with a large monitoring range, a large amount of data can be obtained, which is conducive to deformation monitoring.

[0040] Based on the above, the working principle of the monitoring method and system for the state of the cross beam during the building construction process is as follows:
[0041] First, when using this device, first place this device in the working area, and then connect the device to an external power source to provide the power required for the operation of this device.
[0042] Second, the staff first checks and cleans the surface of the cross beam; then applies the resin coating for fixation to the bottom of the coating suction cup 355, and then fixes it through the insertion of the insertion rod on the side of the fixing block 353 into the fixing colloid 351. Under the limiting action of the metal fixing ring 352, the coating suction cup 355 and the fixing connecting plate 354 are fixed to the bottom of the fixing colloid 351. At the same time, the target 36 is fixed on the top of the fixing colloid 351 by using the fixing block 353.

Here, the control monitoring drone (5) and the target (36) perform sensing actions, and combined with the detection data of the detection coil (3542), the jump data of the target (36) caused by vibration during the detection of the deformation of the crossbeam is excluded, thereby improving the quality of the deformation monitoring of the crossbeam; Step 3: When the pulsed light source (32) propagates in the strain optical cable (34), the incident pulsed light will undergo backscattering to form different backscattered lights. Then, the detection circuit (33) detects the frequency change of the backscattered light in the strain optical cable (34) to sense the changes in temperature and strain reflected by the strain optical cable (34), directly obtains the frequency data of the strain optical cable (34) in each state, and then calculates and analyzes the change of the frequency shift data to obtain the strain; Step 4: Then, the micro air pump (61) provides negative pressure action for the rotating base ball (65) and the negative pressure suction cup (66), so that the first light sensing element (67) and the return spring (68) are adsorbed and fixed at the bottom of the rotating base ball (65). The control system (4) provides electrical energy for the arranged magnetic plates (63) inside the magnetic isolation cylinder (62), so that the permanent magnet sphere (64) and the rotating base ball (65) rotate inside the magnetic isolation cylinder (62) due to magnetic field factors, enabling the ball (610) at the bottom of the second light sensing element (69) to contact the surface crack of the crossbeam. Subsequently, the jump data of the crossbeam crack during the construction lifting is detected through the light sensing detection function between the first light sensing element (67) and the second light sensing element (69).
