<\/h2>\n<\/h2>\nAmong the safety hazards on construction sites, tower crane accidents accounted for as many as 34% of casualties. The tower crane overturning accident that occurred in a commercial complex project in a capital city last year directly caused three deaths and economic losses of more than 20 million yuan. The post-mortem investigation found that if a tower crane safety monitoring system was installed, this tragedy could be completely avoided. Data show that after the installation of a professional monitoring system, the tower crane accident rate has dropped by 85%, and the efficiency of identifying major hidden dangers has increased by 90%. The latest "Regulations on the Safety Supervision and Management of Construction Lifting Machinery" issued by the Ministry of Housing and Construction clearly requires that all newly started tower cranes must be equipped with a monitoring system that meets the GB\/T 5031 standard from 2024. Violators will face shutdown and rectification and a fine of up to 500,000 yuan (link to the original text of the Ministry of Housing and Construction).<\/p>\n
This system is like a \u201dhealth wristband\u201d for tower cranes, tracking eight key parameters in real time: the lifting capacity monitoring accuracy reaches \u00b11%, the amplitude measurement error is less than 0.5 degrees, the height limit response time is 0.2 seconds, and the wind speed warning range is adjustable from 4 to 20m\/s. More advanced is the three-dimensional stereoscopic monitoring capability - through the high-definition camera of the hook, the operator can clearly identify the connection parts the size of nuts from a height of 50 meters. The dual-axis tilt sensor can detect a tower body tilt of 0.1 degrees. The intelligent anti-collision module can simultaneously monitor the operation trajectories of three surrounding devices. In a super high-rise project of a certain central state-owned enterprise in Xiongan New Area, the system successfully warned of a 0.3mm settlement deviation of the tower crane foundation, avoiding the potential risk of overturning.<\/p>\n
Through an industrial-grade 5G Internet of Things gateway, the system uploads encrypted data packets to the cloud every three seconds. The project manager can open the \u201dTower Crane Cloud Control\u201d APP on the mobile phone to simultaneously monitor the operation heat maps of all tower cranes within a 20-kilometer radius. When the torque value exceeds the limit of 90%, the platform automatically triggers a three-level response: first, it sends a pulse vibration warning to the operator's cab. If the problem is not corrected within 5 seconds, an alarm text message will be sent to the safety director. When the critical value is reached, the rotary power supply is remotely cut off. This mechanism successfully prevented overloading hoisting at a metro construction site in Zhengzhou. At that time, the operator forcibly lifted an extremely heavy steel structure, and the system automatically cut off the power when the load reached 110%, with the lifted object suspended 10 meters above the ground (case study of the smart construction management platform).<\/p>\n
The current mainstream configuration in the market has a total investment of about 28,000-55,000 yuan (including installation), which mainly includes\uff1a<\/p>\n
Don't panic when you encounter a data transition! The three most common types of faults are dealt with like this\uff1a Look for three certificates and one report: special equipment manufacturing license, explosion-proof certification (EXDCTCT6), measuring instrument type approval certificate, and third-party EMC test report. The three major echelon brands in the market have their own advantages\uff1a<\/p>\n The system adopts a \u201ddouble insurance\u201d storage solution: detailed data for 90 days is stored on a local industrial SD card (with a sampling frequency of 10Hz), and key operation records are permanently saved on the cloud server. In the investigation of a certain accident in Chongqing, it was precisely the data of the black box three minutes before the overturning that was retrieved, clearly restoring the entire process of overloading - wobbling - instability. A more intelligent system now has predictive capabilities - by analyzing the motor current curve of over 100,000 hours, it can issue a warning of reducer faults 300 hours in advance, and the maintenance response time has been shortened by 70% (data report from China Construction Machinery Research Institute).<\/p>\n With the integration of the Internet of Things and BIM technology, a new generation of tower crane safety monitoring system is developing in the direction of digital twins. In the construction of the Hangzhou Asian Games venue, the system maps the operation data of the tower crane to the BIM model in real time to realize the centimeter-level hoisting path planning.<\/p>","protected":false},"excerpt":{"rendered":" 1. \u4e3a\u4ec0\u4e48\u8981\u5b89\u88c5\u5854\u673a\u5b89\u5168\u76d1\u63a7\u7cfb\u7edf\uff1f \u5728\u5efa\u7b51\u5de5\u5730\u7684\u5b89\u5168\u9690\u60a3\u4e2d\uff0c\u5854\u673a\u4e8b\u6545\u9020\u6210\u7684\u4f24\u4ea1\u5360\u6bd4\u9ad8\u8fbe34%\u3002\u53bb\u5e74\u67d0\u7701\u4f1a\u57ce\u5e02 […]<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[97],"tags":[],"class_list":["post-7828","post","type-post","status-publish","format-standard","hentry","category-technical-support"],"_links":{"self":[{"href":"https:\/\/www.wtauserver.com\/en\/wp-json\/wp\/v2\/posts\/7828","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.wtauserver.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.wtauserver.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.wtauserver.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.wtauserver.com\/en\/wp-json\/wp\/v2\/comments?post=7828"}],"version-history":[{"count":1,"href":"https:\/\/www.wtauserver.com\/en\/wp-json\/wp\/v2\/posts\/7828\/revisions"}],"predecessor-version":[{"id":7831,"href":"https:\/\/www.wtauserver.com\/en\/wp-json\/wp\/v2\/posts\/7828\/revisions\/7831"}],"wp:attachment":[{"href":"https:\/\/www.wtauserver.com\/en\/wp-json\/wp\/v2\/media?parent=7828"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.wtauserver.com\/en\/wp-json\/wp\/v2\/categories?post=7828"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.wtauserver.com\/en\/wp-json\/wp\/v2\/tags?post=7828"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
\n\u200b\u200bData drift\u200b<\/strong>\u200b: Mostly due to strong magnetic interference, immediately wrap the sensor with a magnetic shield (the magnetic storm causes abnormal data after a heavy rainstorm in a certain project, and it will be restored within 2 hours after shielding)
\n\u200b\u200bVideo caton\u200b<\/strong>\u200b: Check the 4G signal strength>-85dBm, or switch to the 5GHz frequency band (a construction site in Guangzhou solves it by adjusting the antenna angle)
\n\u200b\u200bFalse alarm\u200b<\/strong>Repeat the normal operation three times under the \u201dLearning Mode\u201d in the system Settings (the false alarm rate of the Beijing project dropped from 15% to 1%).
\nBe sure to be equipped with an emergency bypass switch to maintain basic operating capabilities in the event of a failure. Power-off and restart 3 times a month can prevent 80% of software failures.<\/p>\n6. How to choose a reliable brand?<\/h3>\n
\n
\nIt is recommended to give priority to brands with local spare parts depots. A project in a third-tier city was delayed by 2 weeks due to other core boards, which has a profound lesson.<\/span><\/li>\n<\/ul>\n7. Data storage and in-depth application<\/h3>\n
