Safety helmet wearing management system based on BIM

Abstract

The invention discloses a safety helmet wearing management system based on a BIM. The safety helmet wearing management system comprises a safety helmet, a pressure sensor, a first positioning chip, asecond positioning chip, an alarm device, an RFID reading receiver, a data storage of BIM integration, a BIM central processing unit and an operation terminal. The pressure sensor is placed on the inner side of a helmet brim of the safety helmet. The alarm device is installed outside a helmet shell of the safety helmet. The alarm device is connected with the pressure sensor through a data line. The first positioning chip and the second positioning chip are arranged on the safety helmet. The RFID reading receiver is connected with the data storage of the BIM integration and then connected withthe BIM central processing unit and the operation terminal through a network transmission device. The operation terminal is provided with a green light positioning indicator lamp and a red light positioning indicator light. It is comprehensively ensured that an on-site constructor correctly wear the safety helmet, the position of a worker is accurately positioned, it is avoided that the worker drops the safety helmet due to objective reasons, and the risks of a construction site are reduced to the minimum.

Description

technical field [0001] The invention relates to the field of safety management in building construction, in particular to a BIM-based helmet wearing management system. Background technique [0002] As China's urban construction has entered a period of comprehensive and rapid development, construction projects have spread all over the land of China. And more and more construction workers are engaged in construction projects, so construction safety has become a very important topic. There are many safety risk factors on construction sites, such as falling objects from heights, workers falling, and there are many sharp objects on the construction site, which may cause injury to workers. Hard hats serve as a protective item that protects workers from some of these injuries. However, although the current construction site workers are forced to wear safety helmets, and punitive measures have been formulated for not wearing safety helmets, there are still people who ignore safety...

Problems solved by technology

However, although the current construction site workers are forced to wear safety helmets, and punitive measures have been formulated for behaviors that do not wear safety helmets, there are still people who ignore safety protection regulations and have a fluke mentality

There is also a safety helmet that falls off accidentally, and the staff only pay attention to the work without wearing it again, which also poses a great safety hazard; if the worker's safety helmet falls off due to other reasons, and the management staff does not find out in time, it will also lead to safety accidents.

[0003] CN201410638339.4 discloses a safety helmet disengagement alarm system, including a cap shell, a cap liner and a chin strap, a cap liner is installed inside the cap shell, a chin strap is symmetrically installed on both sides of the lower end of the cap shell, and the cap shell is composed of a shell, a visor , hat brim, and top ribs to ensure that construction workers wear helmets correctly, which is convenient for safe construction management; however, the specific position of workers wearing helmets cannot be accurately read and understood

CN201610164584.5 discloses a safety helmet with attendance and positioning functions, which includes a monitoring computer, a card reader with an I / O interface and a construction area card reader, and is connected through the Internet to solve the cumbersome and cumbersome management of real-name system attendance management and construction problems. On-site safety management of workers; combined with BIM to accurately locate workers, but cannot manage whether workers wear safety helmets correctly

CN201510985033.0 discloses a safety helmet, which includes a cap shell for accommodating the head space, and also includes a mounting frame, a pressure sensor and a communication unit to solve the problem that staff cannot effectively call for help in an emergency, but it is only suitable for Calling for help in an emergency situation is lacking in the management of whether the helmet is normally worn
