The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.
Techniques, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
Example one
As shown in fig. 1, which is only one embodiment of the present invention, the present invention provides a safety monitoring and early warning method for a movable stand, including the following steps:
s1: dividing the movable stand into at least one independent stand unit;
in practice, the movable stands are divided according to the installation of the installation beams of the movable stands, preferably, the independent stand units are divided according to the installation beams and the stand surfaces above the installation supporting beams on the installation beams, and the independent stand units correspond to the installation beams supporting the independent movable units one by one.
In addition, in the movable stand, the independent two-layer movable stand must be divided into two or more different independent stand units, and the movably connected two-layer movable stand must also be divided into two or more different independent stand units, so that the influence between the two independent stand units is reduced, and the independence of each independent stand unit is ensured.
S2: generating a predetermined loading threshold for each individual stand unit;
here, the predetermined load threshold value of each individual stand unit may be the same or different, and should be generated by combining the characteristics of the mounting beam corresponding to each individual stand unit and the position where the individual stand unit is located, the predetermined load threshold value of each individual stand unit is small if the individual stand unit of the movable stand having a long moving distance or the individual stand unit having a simple mounting structure, and the predetermined load threshold value of the individual stand unit is large if the individual stand unit having a stable mounting structure is mounted.
If the mounting beam is thin or the independent stand unit is supported by wood, the preset load threshold value of the independent stand unit is small; and on the contrary, if the mounting beam is thicker or the independent stand unit supported by the prefabricated plate is adopted, the preset load threshold value of the independent stand unit is larger.
In any case, the preset load threshold value of the independent stand unit is far smaller than the maximum load of the independent stand unit, and the early warning is timely carried out before the independent stand unit is substantially damaged, so that an early warning space is reserved.
S3: monitoring the deformation of the independent stand unit in real time;
the laser ranging sensors are arranged in a dot matrix mode, the distance of the stage surface of the movable stand is detected, and the deformation of each independent stand unit is monitored in real time.
A plurality of laser ranging sensors are distributed below each independent stand unit, the number of the laser ranging sensors is required to be more than 3, and the laser ranging sensors are used for measuring the deformation of the movable stand surface.
The laser ranging sensor adopts a non-contact measurement principle, does not need to apply external force on a measured object, and has high detection accuracy.
S4: calculating a load value of the current independent stand unit corresponding to the deformation of the current independent stand unit;
in fact, the PC end is preferably adopted for calculation, the PC end is connected with the laser ranging sensor and used for receiving the measurement data of the laser ranging sensor, analyzing and processing the data, and determining the integral reference threshold corresponding to the instant deformation data based on the distribution condition of the instant deformation data.
Before step S4 is executed, objects of different masses are placed on each individual stand unit in advance, deformation quantities of the individual stand units caused by the masses on each individual stand unit are obtained, and the deformation quantities are stored in a storage table one by one. In a word, before actually monitoring the safety of the stand, firstly, the method needs to be calibrated, a load with a specified weight is placed on the movable stand surface, the direct relation between the deformation of the movable stand and the load is tested, and after the data is stored, the step is not needed to be carried out subsequently.
And after the data is stored, the PC terminal acquires the measurement data of the laser ranging sensor, obtains the deformation of the current independent stand unit, calculates the deformation of the current independent stand unit, and reads the corresponding load value of the current independent stand unit from the storage table.
S5: judging whether the load value of the current independent stand unit is smaller than a preset load threshold value of the current independent stand unit; if yes, return to step S3; otherwise, an early warning signal is sent out.
Certainly, when step S5 is executed, each individual stand unit is numbered, and the real-time load value of the individual stand unit is not less than the predetermined load threshold value of the individual stand unit, then the number information of the individual stand unit is added to the warning signal, which is convenient for the staff to maintain or evacuate the crowd in time.
The safety monitoring and early warning method for the movable stand is convenient to execute, stable and reliable, can acquire the load condition of the movable stand without applying external force on a measured object based on the laser ranging principle, is high in identification precision, convenient to install in the later period, strong in practicability and suitable for popularization.
