随着我国建筑行业的发展以及用地的紧缩，为了缩短项目工期，多建筑密集高效施工已成为土木行业的常态。塔吊作为施工领域的重要角色，其作业环境日益复杂，然而传统吊装作业采用操作员与吊装员相互配合的方式指挥塔吊交叉重叠作业。虽然这些专业人员需要考取相关驾驶证和具备一定文化水平方能上岗，但这种方法总体上智能化较低，信息对接不准确或及时，难以应对某些复杂情况。近年来塔吊机碰撞事故高发也逐渐印证了这一点。传统的依靠人工值守的监测技术逐渐无法满足现代化施工工地上塔吊机群的防碰撞预警需求，急需一类能够实时监控塔吊机吊装运行且能发出预警信号的建筑施工群塔防碰撞预警监控方法。With the development of my country's construction industry and the contraction of land use, in order to shorten the project period, intensive and efficient construction of multiple buildings has become the norm in the civil engineering industry. As an important role in the construction field, tower cranes have an increasingly complex operating environment. However, traditional hoisting operations use the cooperation of operators and hoisting personnel to direct the overlapping operations of the tower cranes. Although these professionals need to obtain a relevant driver's license and have a certain level of education to be able to work, this method is generally less intelligent, and the information is not accurate or timely, and it is difficult to deal with some complex situations. In recent years, the high incidence of tower crane collision accidents has gradually confirmed this. The traditional monitoring technology that relies on manual duty gradually cannot meet the anti-collision warning requirements of the tower crane group on modern construction sites. There is an urgent need for a kind of building construction group tower anti-collision warning monitoring method that can monitor the hoisting operation of the tower crane in real time and can send out warning signals.
