[0070] In the embodiment of the present invention, the safety monitoring system 500 includes a usage status monitoring module 501, a construction monitoring module and a multi-level safety early warning module 503;

[0071] The state monitoring module 501 uses sensors to monitor the state of the safety operation platform, including pressure, displacement and tilt;

[0072] The construction monitoring module uses a camera to monitor the construction of the operator. The construction monitoring module includes a construction behavior recognition unit 5021. The construction behavior recognition unit 5021 uses human behavior recognition technology to monitor the construction behavior of the construction personnel on the platform and judge the working status of the construction personnel.

[0073] The multi-level security warning module 503 establishes a multi-level security warning mechanism to issue different levels of alarms according to risk levels, so as to facilitate the adoption of corresponding processing methods and response speeds according to different levels of alarms.

[0074] In an embodiment of the present invention, the usage status monitoring module 501 includes a data acquisition unit 5011, a data analysis unit 5012, and a blockchain data storage unit 5013;

[0075] The data acquisition unit 5011 is used to collect sensor data, integrate the data, and provide a data source for subsequent processing;

[0076] The data analysis unit 5012 compares the data from the data acquisition module with a preset threshold value, and analyzes whether the current data exceeds the threshold value and the difference between the current data and the threshold value;

[0077] The blockchain data storage unit 5013 uses blockchain technology to store the data collected by the data collection unit 5011 on the blockchain, and ensures the security and reliability of the data through the decentralization and encryption characteristics of blockchain technology, including:

[0078] Collect platform status and surrounding environment data in real time, such as inclination, load, wind speed, etc., perform preliminary processing on the collected data, such as filtering and denoising, encrypt the pre-processed data, write the encrypted data into the blockchain to form data blocks, and store the blockchain data on multiple nodes. Once the data is written into the blockchain, it cannot be modified, which ensures the integrity and credibility of the data. Encryption technology is used to ensure the security of data during transmission and storage.

[0079] The multi-level security warning module 503 divides the warning levels into:

[0080] Level 1 warning means that the difference between the real-time data and the preset threshold is small and within a reasonable range, indicating that there is a slight risk that does not affect normal use and needs to be processed in time. For example, assuming that the set threshold of the tilt sensor is 1 degree, when the sensor detects that the platform tilt angle is 1.5 degrees, a level 1 warning is triggered;

[0081] Level 2 warning means that the value exceeding the threshold affects the use of the operating platform, but it can still be used and immediate measures need to be taken. For example, assuming that the pressure sensor threshold on the limit plate is aN, when the pressure sensor detects that the pressure value on the limit plate is a+10N, the level 2 warning is triggered;

[0082] Level 3 warning means that the preset threshold is beyond the reasonable range, the operating platform cannot be used, and the operation needs to be stopped immediately and emergency measures need to be taken. For example, assuming that the severe tilt threshold of the tilt sensor is 5 degrees, when the sensor detects that the platform tilt angle is 6 degrees, the level 3 warning is triggered.

[0083] Embodiment 2

[0084] See attached Figure 8 As shown, an embodiment of the present invention further provides a construction method of an external tower crane safety operation platform, comprising the following steps:

[0085] Step S1, determining the installation position of the operating platform according to the position and height of the tower crane;

[0086] Step S2, using the structural parts of the tower crane to firmly fix the platform on the tower crane, fixing one end of the high-strength steel wire rope to the suspension point of the platform body, and fixing the other end to the structural parts of the tower crane, and keeping the platform level by adjusting the length of the steel wire rope;

[0087] Step S3: After the platform is installed, a safety check is performed to ensure that all safety devices are working properly;

[0088] Step S4, select the use of the primary platform 100 and the secondary platform 200 according to the operation requirements, perform normal operations on the primary platform 100, and when using the secondary platform 200, control the operation of the push rod 305 of the lifting base 301 below through the controller 207 on the secondary platform 200, control the lifting and lowering of the X-shaped support rod through the push rod 305, and the other synchronous X-shaped support rods are connected by bolts or screws. The lifting height of the lifting chassis 300 is selected according to the use requirements. When it is necessary to expand the operation area of ​​the secondary platform 200, manually remove the bolts fixed between the moving plate 203 and the bottom of the support plate 201, push the moving plate 203, and the synchronous upper end slide bar 205 and the movable rod 407 of the moving plate 203 move on the fixed bar on the support plate 201 to adjust the operation area of ​​the secondary platform 200. After the adjustment is completed, the position of the moving plate 203 is fixed with bolts to complete the expansion of the secondary platform 200;

[0089] Step S5, the operator performs the hoisting operation of the tower crane through the controller 207 on the secondary platform 200;

[0090] Step S6, a safety rope is tied to the operator, and the other end of the safety rope is installed on the safety rope clamp 400. The safety rope clamp 400 is selected at a reasonable position according to the operating range for connection. The outer hoisting ring 401 of the safety rope clamp 400 is fixed in position by cooperating with the threaded end 403 through the nut 404. After the safety rope passes through the outer hoisting ring 401, it is looped back and passed through the inner hoisting ring 405 to fix the safety rope. When the worker moves, due to the tension of the safety rope, the inner hoisting ring 405 will be pulled, and the movable rod 407 in the connecting tube 406 on the inner hoisting ring 405 will move synchronously and pass through the position The limit block 408 on the movable rod 407 at the bottom of the fixed seat 402 limits the movement of the movable rod 407 to prevent the safety rope from pulling out the inner ring 405. When the limit block 408 is pulled, the pressure data monitored by the pressure sensor can reflect the tension on the safety rope. The pressure applied by the inner ring 405 to the limit block 408 will be transmitted to the safety rope. The pressure sensor can monitor and record these pressure changes in real time, so as to know the tension on the safety rope. The movement data of the limit block 408 monitored by the displacement sensor can reflect the displacement of the safety rope. When the limit block 408 is pulled, the limit block 408 will be displaced. The displacement sensor can monitor and record these displacement changes in real time, so as to know the displacement of the safety rope.

[0091] Step S7, using the security monitoring system 500 to monitor the status of the operating platform and the safety of the operators in real time, by presetting the thresholds of various data in the data analysis unit 5012, and using relevant sensors to transmit real-time data, and comparing it with the threshold, the multi-level security warning module 503 determines the warning level according to the difference between the real-time data and the threshold, and issues a warning in time, performs corresponding processing according to different levels, and processes the data through blockchain, and saves the data to facilitate subsequent processing, such as using deep learning technology for data prediction.

[0092] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
