Round Table Forum：Safety problems in the use of construction hoisting machineryVisualization Application and Information Technology Prevention Means
Round Table Forum Dialogue Session，Vice President of Safety Management and Machinery Leasing Service Branch of China Safety Industry Association、Hosted by Zhu Hui, Chief Operating Officer of Dafeng China，Li Xiaosong, General Manager of Wuhan Gangdi Technology Co., Ltd.、Song Shijun, Professor of Shandong Jianzhu University、Peng Shanzhong, Chairman of Chengdu Keda Photoelectric Technology Co., Ltd.、Yang Jing, Technical Director of Xi'an Fengshu Electronic Technology Development Co., Ltd.、Deng Ping, Assistant General Manager of Changsha Haichuan Automation Equipment Co., Ltd.“Visual Application and Information Technology Prevention Means of Safety Problems in the Use of Construction Hoisting Machinery”A round-table forum dialogue was held on this theme.。
Li Xiaosong pointed out the brake failure protection function before lifting.、Development and application of the quick stop function of slewing mechanism in case of sudden power failure，It will essentially improve the safety performance of tower crane.。The anti-swing function of the luffing slewing mechanism and the stable lifting function of the lifting mechanism of the intelligent tower crane are the intelligent tower crane.（Unmanned tower crane）The basic function of，Need to be solved in control。
Song Shijun aims at unmanned tower crane、Current Situation of Tower Crane Visual Accessories Field，Unmanned tower crane is proposed、Safety measures for tower crane structure are required for remote control。The potential safety hazard and structural characteristics of tower crane are analyzed。The team was introduced.，Shandong Fuyou is mainly engaged in the application and development of digital information technology，The tower crane has been completedCT、Structural health status diagnosis and other technologies，Shandong Fuyou's tower crane structure damage warning product can warn the collapse of the tower crane one month in advance.。
Peng Shanzhong pointed out the technology of digital image and communication signal unimpeded of tower crane，The combination of unmanned driving and communication is the trend in the future.，The existing communication carrying mobile phone has the characteristic of delay，It is expected to achieve 6 in five yearsG，Breakthrough communication chip technology is the focus of the future。
Yang Jing proposes to use digital technology to achieve controllable cost.、Increase profits。Devices have the same analysis as people.、Ability to deal with problems，Achieve technological breakthroughs。The existing systems carried by the tower crane are not interoperable，Resulting in higher costs，Safety is an industry-wide affair.，Manufacturers focus on the safety of the tower crane itself.，This is single scene security.，General ConTractor，The leasing unit is not only concerned about the safety of the tower crane itself，And tower cranes are safe to use.，This belongs to multi-scenario security.， The competent government department is responsible for the safety of the whole process of testing.，This is the whole life cycle safety.，Realize the security control of each scene in the above three links，Combining model technology，With technology，Develop new systems，Break the existing dilemma。
Deng Ping believes that both the monitoring system and the visualization system on the market at present，Or driverless in the future?，Can not be separated from the monitoring and measurement of the operation status and command control signals of the tower crane elevator.，If the control system is the brain,，So these sensors are glasses.、Ears and tentacles。At present, there are two main directions in the research of perception technology.，It includes the digital transformation of traditional safety components and control components and the introduction of high-precision measurement methods from other industries into the tower crane industry.，For example, the navigation satellite phase difference technology applied in driverless Vehicles is introduced into the state detection of tower cranes.，0 can be achieved.High precision rotation angle measurement of 02 degrees，And that verticality of the tow crane can be met through a composite algorithm at the same time.、High precision measurement of structural load。
