[0002] The construction industry is a traditional industry. It is an important material production sector and one of the pillar industries. With the continuous development of the construction industry and the continuous advancement of technology, the market demand for tower cranes will continue to grow. Tower cranes have strong lifting capacity and flexible working radius, and can efficiently transport and install heavy construction materials and equipment. They are important equipment in the field of modern construction and engineering. Due to the extensive production management methods and backward management methods of on-site personnel and machines, there are widespread problems. How to strengthen construction site safety management, reduce the frequency of accidents, and eliminate various illegal operations has become an urgent problem to be solved. Therefore, it is particularly important to invent a method and system for all-weather monitoring of construction site equipment.

[0003] The existing all-weather monitoring methods and systems for construction site equipment still have the following defects, which are specifically reflected in: 1. In the existing all-weather monitoring methods and systems for construction site equipment, there is not much attention paid to the early warning of the dangerous area of ​​tower crane tilting. If the early warning of the dangerous area of ​​tower crane tilting is not timely, it will cause casualties and property losses in the dangerous area of ​​tower crane tilting, thereby reducing the overall construction efficiency, damaging the image of the entire construction industry, and reducing the public's trust in construction safety.

[0004] 2. In the existing all-weather monitoring methods and systems for construction site equipment, not much attention is paid to the foundation of the tower crane. The foundation of the tower crane sinks, causing cracks or deformation in the foundation of the tower crane, reducing the overall stability of the tower crane. The tower crane may collapse due to loss of stable support, causing casualties and property losses, and increasing the probability of accidents involving the tower crane. Summary of the invention

[0005] The purpose of the present invention is to provide a method and system for all-weather monitoring of construction site equipment, which solves the problems existing in the background technology.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a method for all-weather monitoring of construction site equipment, including: step one, meteorological safety monitoring and analysis, obtaining real-time meteorological data of the tower crane working area through a meteorological monitoring station, analyzing the real-time meteorological data of the tower crane working area, and judging whether the weather in the tower crane working area is abnormal; if the weather in the tower crane working area is abnormal, generating a weather abnormality strategy for the tower crane working area; if the weather in the tower crane working area is normal, judging whether the operation safety of the tower crane is abnormal, and judging whether the foundation safety of the tower crane is abnormal.

[0007] Step 2: Structural safety monitoring and analysis: Use stress sensors to obtain the stress of key parts of the tower crane and determine whether the structure of the tower crane is abnormal.

[0008] Step 3: Operational safety monitoring and analysis: Use high-definition cameras to obtain the facial features of people climbing the tower crane, obtain the working hours of the tower crane operators, and determine whether the operation of the tower crane is abnormal.

[0009] Step 4: Danger warning: an alarm will be issued when the weather in the tower crane working area is abnormal, the tower crane operation safety is abnormal, the tower crane foundation safety is abnormal, the tower crane structure is abnormal, and the tower crane operation is abnormal.

[0010] Preferably, the specific analysis method for judging whether the weather in the tower crane working area is abnormal is as follows: extracting the wind force level at each time point in the real-time meteorological data of the tower crane working area, and comparing it with the wind force safety level stored in the database; if the wind force level at a certain time point in the meteorological data of the tower crane working area is higher than the wind force safety level stored in the database, then it is determined that the weather in the tower crane working area is abnormal; if the wind force level at each time point in the meteorological data of the tower crane working area is lower than the wind force safety level stored in the database, then it is determined that the weather in the tower crane working area is normal.

[0011] The electric field strength at each time point in the real-time meteorological data of the tower crane working area is extracted. If the electric field strength at a certain time point in the meteorological data of the tower crane working area is higher than the safe electric field strength stored in the database, it is determined that the weather in the tower crane working area is abnormal; otherwise, it is determined that the weather in the tower crane working area is normal.

If the final tilt angle of the tower crane body is greater than the preset tilt angle of the tower crane body, the tower crane safety is determined to be abnormal, and a tower crane tower body tilt danger zone is generated. Otherwise, the tower crane is determined to be safe and normal. Similarly, if the final tilt angle of the tower crane arm is greater than the preset tilt angle of the tower crane arm, the tower crane safety is determined to be abnormal, and a tower crane arm tilt danger zone is generated. If the final tilt angle of the tower crane body is greater than the preset tilt angle of the tower crane body, and the final tilt angle of the tower crane arm is greater than the preset tilt angle of the tower crane arm, a tower crane tilt danger zone is generated.
