技术领域technical field
本发明设计工程管理及电子信息技术领域，具体说涉及一种基于全域变频定位与自识别技术的智慧工地管理系统。The present invention is in the field of design engineering management and electronic information technology, and specifically relates to an intelligent construction site management system based on global frequency conversion positioning and self-identification technology.
背景技术Background technique
智慧工地是指运用信息化手段，通过三维设计平台对工程项目进行精确设计和施工模拟，同时围绕施工过程管理，建立互联协同、智能生产、科学管理的施工项目信息化生态圈，实现工程施工可视化智能管理，以提高工程管理信息化水平和实现绿色建造和生态建造。Smart construction site refers to the use of information technology to carry out precise design and construction simulation of engineering projects through a three-dimensional design platform. At the same time, around the construction process management, an information ecosystem of construction projects that is interconnected, collaborative, intelligent production, and scientific management is established to realize engineering construction visualization. Intelligent management to improve the level of project management informatization and realize green and ecological construction.
现有的工地管理系统在人员和设备的管理、施工进程的管理和环境的监测等方面存在严重的技术缺陷，例如在人员和机械设备定位方面，由于施工队伍和设备流动性大，工人身份难以验证；工人出勤缺乏电子记录，工资核算与支付证据链不清，劳资纠纷频繁发生。目前的定位和识别方法主要依赖于电子标签和GPS定位，由于GPS易受到了遮蔽物的影响而产生较大的定位偏差，由此得到的定位难以用于构建准确的建筑信息模型；而应用RFID、蓝牙或wifi进行室内定位，由于定位距离短，难以应用于大范围的施工环境的人员与设备管理。另外，数据的传输依赖于手机基站或网络系统，在偏远山区或信号盲区难以实现实时有效的信息传输。由此看来，缺乏实时有效的人员与设备定位措施是制约目前智慧工地管理的瓶颈问题。例如中国专利CN201510628958和CN201610173074设计的智慧化工地管理系统中缺失关于施工人员和机械设备的定位信息和状态监测信息，难以实施进度的三维信息重构；中国专利CN201220675601智慧工地管理系统中虽然引入了车辆GPS定位系统，但缺少人员定位和状态信息的监测功能，难以实现人员考勤与施工过程的实时管理；中国专利CN201310324645一种工地数字化管理系统及其应用方法中对于人员或设备的定位采用了RFID无线射频技术，并借助手持式RFID读头来获取相关的人员或设备信息。由于该系统的探测范围非常小，无法实现较大的施工现场的管理，另外需要进行手持式RFID读头来巡回读取，成本较高且无法获得人员的健康状态；专利CN201710032035.7引入GPS和传感器模块来实现定位和状态感知功能，但仅能局限于室外有GPS信号的区域，难以实现遮挡区域的定位信息；中国专利CN201611254619.0引入记录人员信息的RFID铭牌和室内读写器来定位和识别医院病房内的人员，但该方案仅能用于室内定位；中国专利CN201420497173.4采用基于BIM的RFID工地人员自动定位系统装置来实现施工建筑内的定位，但难以实现大范围的准确定位。The existing construction site management system has serious technical defects in the management of personnel and equipment, the management of construction progress and the monitoring of the environment. Verification; lack of electronic records of workers' attendance, unclear chain of evidence between wage accounting and payment, and frequent labor disputes. The current positioning and identification methods mainly rely on electronic tags and GPS positioning. Because GPS is susceptible to the influence of shelters and produces large positioning deviations, the resulting positioning is difficult to use to build accurate building information models; and the application of RFID , Bluetooth or wifi for indoor positioning, due to the short positioning distance, it is difficult to apply to personnel and equipment management in a large-scale construction environment. In addition, data transmission depends on mobile phone base stations or network systems, and it is difficult to achieve real-time and effective information transmission in remote mountainous areas or signal blind areas. From this point of view, the lack of real-time and effective personnel and equipment positioning measures is the bottleneck problem restricting the current smart construction site management. For example, the intelligent construction site management system designed by Chinese patents CN201510628958 and CN201610173074 lacks positioning information and status monitoring information about construction personnel and mechanical equipment, and it is difficult to implement three-dimensional information reconstruction of progress; although the intelligent construction site management system of Chinese patent CN201220675601 introduces vehicles GPS positioning system, but it lacks the monitoring function of personnel positioning and status information, and it is difficult to realize the real-time management of personnel attendance and construction process; Chinese patent CN201310324645 is a kind of site digital management system and its application method, which uses RFID wireless for the positioning of personnel or equipment. Radio frequency technology, and with the help of handheld RFID readers to obtain relevant personnel or equipment information. Since the detection range of this system is very small, it is impossible to realize the management of a large construction site. In addition, a handheld RFID reading head is required for roving reading, which is costly and cannot obtain the health status of personnel; patent CN201710032035.7 introduces GPS and The sensor module is used to realize positioning and state perception functions, but it can only be limited to areas with GPS signals outdoors, and it is difficult to achieve positioning information in blocked areas; Chinese patent CN201611254619.0 introduces RFID nameplates and indoor readers that record personnel information to locate and Identify people in hospital wards, but this solution can only be used for indoor positioning; Chinese patent CN201420497173.4 uses a BIM-based RFID site personnel automatic positioning system device to achieve positioning in construction buildings, but it is difficult to achieve accurate positioning in a wide range.
综上所述，大范围复杂环境下工地施工人员与设备的有效监控是实现智慧工地的重要途径。但现有技术中并没有行之有效的方案来解决人员与设备的准确定位和状态监测问题。To sum up, the effective monitoring of construction personnel and equipment in a large-scale and complex environment is an important way to realize a smart construction site. However, there is no effective solution in the prior art to solve the problems of accurate positioning and status monitoring of personnel and equipment.
